Full textAbstract:
The ever increasing demand of our information society for reliable Geographic Information (GI) is the moving power for the development and maintenance of Spatial Data Infrastructures (SDI). Consequently, an SDI works to full benefit of its users if the SDI data collection is accessible and can be efficiently used by all users in spatial problem solving and decision-making. Current development and use of SDI focuses on handling geospatial data entirely by means of information technology. Thereby, low awareness seems to be paid to a user-friendly and understandable presentation of geospatial data. Based on the understanding that GI is the result of human geospatial information processing, it is argued that cartography is essential in the SDI context in order to achieve the objectives of SDI. Specifically, the thesis aimed at exploring the concept of user-oriented map design in relation to SDI and elaborating a methodology for creating effective cartographic representations for SDI relevant user types. First of all, the SDI concept, its objectives and principles are explored using the example of the current European SDI initiatives as to the human aspect of an SDI. Secondly, in order to determine the role and task of cartography in the SDI context, the conceptual framework of contemporary cartography is reviewed to provide the theoretical and technological framework for a user-oriented map design. Given this, the SDI environment is assessed in relation to cartography with respect to the services providing access to the SDI data collection. Further, an SDI map production framework is elaborated utilising Spiess’ concept of the graphic filter as a model for the transformation of SDI data into useful cartographic representations. Besides, the map design strategy by Grünreich provides the starting point for developing the process of map production. The main tasks are detailed and justified taking into consideration the semiotic-cognitive and action-related concepts underpinning contemporary cartography. The applied research encompasses a case study which is performed to implement and, thus, evaluate the proposed methodology. It starts from a use case scenario where an international spatial planning team requires getting familiar with the overall geographic characteristics of a European cross-border area. Following the process steps of user-oriented map design in the SDI environment, a map design specification is elaborated and implemented under real world conditions. The elaborated methodology for creating user-friendly and understandable cartographic representations of geospatial data in the SDI environment is based on theoretical and technological foundation of contemporary cartography. Map design in the SDI context, first of all, means to establish a graphic filter that determines the parameters and rules of the cartographic transformation process to be applied. As both an applied art and engineering the design of the graphic filter is a creative process developing a map design solution which enables SDI users to easily produce their map. It requires on the one hand an understanding of map use, map user and map use situation, and on the other hand insight into the data used as the source. The case study proves that the elaborated methodology is practicable and functional. Cartographic reverse engineering provides a systematic and pragmatic approach to the cartographic design task. This way, map design solutions can be built upon existing cartographic experience and common traditions as suggested by the INSPIRE recommendation for portrayal. The resulting design solution constitutes a prototype of a European Reference Map at medium scale built upon existing cartographic experience and common traditions. A user-friendly, understandable and comparable presentation of geospatial data in Europe would support the human and institutional potential for cross-border cooperation and collaboration. Besides that, the test implementation shows that tools are available which make it technically feasible and viable to produce a map from geospatial data in the SDI data collection. The research project raises awareness to the human aspect of SDI inherit in its objective to support end users to derive GI and knowledge from the geospatial data gathered in the SDI data collection. The role and task of cartography in the SDI context is to contribute to the initiation, creation, and maintenance of portrayal services to facilitate a comprehensive access to the underlying geospatial data by means of a user-friendly and understandable graphic interface. For cartography to take effect in the SDI development and use, cartographic design knowledge has to be made explicit and operational. It is the responsibility of cartographic professionals to prepare the map design. The wide range of map use contexts requires a great flexibility of design variants depending on the dimension of human-map interaction. Therefore, the design of the maps needs to be user-driven to enable an efficient map use in the user’s task. Besides their function as a graphic interface, maps facilitate a common understanding of the depicted geographic features and phenomena when sharing GI between SDI users. In other words, map design can be regarded a measure to establish interoperability of geospatial data beyond the technical level. The research work is in the scope of communication cartography, a research domain seeking to deepen the understanding of the role of cartographic expressions when understanding and communication of GI is involvedDer wachsende Bedarf unserer Wissensgesellschaft an zuverlässigen Informationen über räumliche Strukturen und Sachverhalte ist die treibende Kraft bei Aufbau und Einsatz von Geodateninfrastrukturen (GDI). Eine Geodateninfrastruktur wirkt zum vollen Nutzen der Gesellschaft, wenn die Daten in der GDI zugänglich sind und effektiv für Erkenntnis- und Entscheidungsprozesse genutzt werden können. Die gegenwärtige Entwicklung von GDI setzt auf moderne Informationstechnologien bei der Geodatenverarbeitung. Dabei, wird einer bedarfsgerechten und nutzerfreundlichen Präsentation von Geodaten in ansprechender visueller Form wenig Aufmerksamkeit zuteil. Da Geoinformation erst durch die Interaktion des Nutzers mit den Geodaten entsteht, ist es Aufgabe der Kartographie, bedarfsgerechte Kartendarstellungen zu gestalten und an der Schnittstelle zwischen einer Geodateninfrastruktur und ihren Nutzern bereitzustellen. Ziel der vorliegenden Dissertation ist es, eine Methodik für den Kartenherstellungsprozess in einer GDI-Umgebung zu entwickeln und beispielhaft zu erproben. Zunächst, werden Konzept, Ziele und Prinzipien von Geodateninfrastruktur beispielhaft anhand der Europäischen GDI-Initiativen dargestellt und hinsichtlich des Bedarfs an kartographischen Darstellungen untersucht. Danach wird, ausgehend von der Forderung nach verständlichen und gut interpretierbaren Geoinformationen, die Rolle der Kartographie im GDI-Kontext bestimmt. Dabei werden zunächst Funktion und Aufgaben der Kartographie sowie die tragenden Konzepte und Grundlagen einer nutzerorientierten Kartengestaltung dargelegt. Der Vergleich der bestehenden Geodatenzugangsdienste zur Funktion der Kartographie ergibt eine Lücke, die es zu schließen gilt, um den Nutzeranforderungen gerecht zu werden. Dazu wird der Gesamtprozess für die Herstellung von Karten im GDI-Kontext beschrieben. In diesem Prozess kommt dem Graphikfilter von Spiess (2003) besondere Bedeutung als Modell eines wissensbasierten Systems zur Aufstellung und Umsetzung von kartographischen Gestaltungsregeln zu. Den Ausgangspunkt für die Ausarbeitung der Teilprozesse bieten die von Grünreich (2008) vorgeschlagenen Teilaufgaben der Kartographie im Rahmen der GDI. Mittels eines Anwendungsfalls im Europäischen Kontext wird der vorgeschlagene Gesamtprozess erprobt. Dieses Beispiel geht davon aus, dass eine internationale Planungsgruppe im Zuge der Konzeption einer grenzüberschreitenden Verkehrsverbindung eine anschauliche Beschreibung der Landschaft in Form einer einheitlich gestalteten und flächendeckenden Karte benötigt. Durch Anwendung des kartographischen Reverse Engineering anerkannt gut gestalteter Karten werden die Vorgaben für die Kartengestaltung ermittelt. Einschließlich der Anwendung auf konkrete GDI-Daten wird der zuvor entwickelte Herstellungsprozess ausgeführt und diskutiert. Die entwickelte Methodik für den Kartenherstellungsprozess in der GDI-Umgebung basiert auf den semiotisch-kognitiven und handlungstheoretischen Konzepten der modernen Kartographie. Kartengestaltung im Kontext von Geodateninfrastrukturen bedeutet die Entwicklung eines Graphikfilters, der eine optimale bedarfsgerechte Visualisierung der Geodaten mittels nutzerspezifischer Parameter und Gestaltungsregeln ermöglicht. Wie das Fallbeispiel zeigt, ist es die durch die entwickelte Methodik möglich, brauchbare und nützliche Kartendarstellungen zu gestalten. Die Anwendung des kartographischen Reverse Engineering erlaubt es, Kartendarstellungen zu entwickeln, die - wie von INSPIRE empfohlen - bewährten kartographischen Erfahrungen und allgemeinen Traditionen entsprechen. Das Ergebnis des Anwendungsfalls ist ein Prototyp einer Europäischen Referenzkarte im Maßstab 1: 250,000. Die einheitliche und somit vergleichbare Darstellung über Grenzen hinweg unterstützt das Planungsteam in seiner Arbeit. Die praktische Umsetzung der Karte zeigt zudem, dass funktionsfähige Werkzeuge und Technologien für die regelbasierte Kartenherstellung aus GDI-Daten vorhanden sind. Die Dissertation trägt dazu bei, das Bewusstsein für den menschlichen Aspekt der Nutzung einer Geodateninfrastruktur zu schärfen. Der Beitrag der Kartographie zur Nutzung der Geodaten einer GDI besteht in der Initiierung, Gestaltung und Pflege von Darstellungsdiensten, da die Nutzbarkeit der Geodaten am besten gewährleistet ist, wenn die Gestaltungsmethoden der Kartographie angewendet werden. Dabei liegt es in der Verantwortung der Kartographen, die nutzerseitigen Aspekte dieser graphischen Schnittstelle unter Berücksichtigung der modernen kartographischen Konzepte zu betreuen. Gemäß INSPIRE-Richtlinie werden auf Karten gestützte Informationen bei zahlreichen Tätigkeiten verwendet. Für eine effektive visuelle Informationsverarbeitung durch den Nutzer ist daher eine nutzerorientierte Kartengestaltung in Abhängigkeit von der geplanten Interaktion (z.B. Kommunikation oder Analyse) unerlässlich. Neben der Funktion als Schnittstelle machen kartographische Darstellungen räumliche Strukturen verständlich. Daher ist die Kartenherstellung im GDI-Kontext eine Maßnahme, um Interoperabilität von Geodaten über die technische Ebene hinaus auf menschlicher Ebene zu ermöglichen. Die Relevanz dieser Forschungsarbeit liegt im Bereich der Kommunikationskartographie, die die Effektivität und Verbindlichkeit der Kommunikation über räumliche Strukturen und Sachverhalte zu vertiefen sucht

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, CaliforniaAn orbiting sensor module, designed by The Johns Hopkins University Applied Physics Laboratory (JHU/APL), performed a number of significant Strategic Defense Initiative (SDI) Delta 181 program experiments. These experiments required on-orbit command and monitor operations involving a worldwide network of ground facilities. A major component was the sensor module command center (SMCC), which was designed and integrated by JHU/APL. The SMCC, located at Cape Canaveral Air Force Station (CCAFS), connected to a network of Eastern Test Range, Air Force Satellite Control Network (AFSCN), Kennedy Space Center, and Western Test Range assets. The complex nature of the mission presented numerous challenges to the design, integration, and operation of the SMCC. This paper presents a functional overview of SMCC design as well as unique aspects of supporting ground network telemetry and command operation.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, NevadaOne of several methods currently under investigation to increase telemetry efficiency is channel diversity selection. A spatial technique we are exploring exploits a signal quality indicator of phase demodulation to select ‘competing’ telemetry channels sourced by antenna separated by fractional wavelengths. The Advanced Range Telemetry (ARTM) program, a Centralized Test and Evaluation Improvement Program (CTEIP) research project funded by the Office of the Secretary of Defense (OSD), recently investigated three switching criteria for a multiple antenna system. This paper will discuss an algorithm that controls channel selection, or diversity branch selection (DBS), using a combination of the techniques investigated.

Full textAbstract:
Visual Topology is used here to describe the spatial relations between objects as they appear in the 2D viewing plane. This thesis sets out the concept, explains why it is needed in Geographic Information Science and suggests how it may be computed through development of prototype software. Section 1 considers the functionality that any Spatial Data Infrastructure would need to encompass in order to support the inclusion of visual analysis into landscape planning and monitoring systems. Section 2 introduces various aspects of visual topology. In particular it sets out how visual intersections of occluding edges may be modelled topologically and formally defines a novel higher level topological structure to the viewing space - the 'Euler Zone' based on the Euler complexity of a graph formed by the occluding horizons in a view. Whether such a graph has meaning to an observer is considered in Section 5, which presents the results of a web based forced choice experiment with significant implications for the role of topology in modelling landscape preference via quantitative metrics derived from 20 maps. Sections 3 and 4 discuss how existing methods for handling perspective models and visualisations need to be improved in order to model visual topology. Section 3 focuses on the limitations of current techniques and design criterion for a new methodology. Section 4 looks at the lessons learnt from developing a prototype implementation (VM-LITE) based on Quad-Edge Delaunay Triangulation, in the VoronoiMagic software package. Some potential applications are highlighted, both within landscape modelling and beyond, before drawing conclusions as to the potential for the concepts and methods respectively. Although important research questions remain, particularly as regards view point dynamics, Visual Topology has the potential to fundamentally change how visual modelling is undertaken in GIS. It allows the analysis of scenes based upon a richer representation of individual experience. It provides the basis for data structures that can support the extraction of generalisable metrics from this rich scene information, taking into account the qualitatively different nature of scene topology as distinct from metrics of shape and colour. In addition new metrics based on attributes only apparent in perspective, such as landform, can be analysed. Finally, it also provides a rationale for reporting units for landscapes with some measure of homogeneity and scale-independence in their scenic properties.

Full textAbstract:
We present the results of a survey of 45 young (<250>Myr), close (<50>pc) stars with the Simultaneous Differential Imager (SDI) implemented at the VLT and the MMT for the direct detection of extrasolar planets. Our SDI devices use a double Wollaston prism and a quad filter to take images simultaneously at three wavelengths surrounding the 1.62 um methane absorption bandhead found in the spectrum of cool brown dwarfs and extrasolar giant planets. By performing a difference of adaptive optics corrected images in these filters, speckle noise from the primary star can be significantly attenuated, resulting in photon (and flat-field) noise limited data. In our VLT data, we achieved H band contrasts > 10 mag (5 sigma) at a separation of 0.5" from the primary star on 45% of our targets and H band contrasts of > 9 mag at a separation of 0.5'' on 80% of our targets. With this degree of attenuation, we should be able to image (5 sigma detection) a 7 MJup planet 15 AU from a 70 Myr K1 star at 15 pc or a 7.8 MJup planet at 2 AU from a 12 Myr M star at 10 pc. Using the capabilities of the unique SDI device, we also discovered a methane-rich substellar companion to SCR 1845-6357 (a recently discovered (Hambly et al., 2004) M8.5 star just 3.85 pc from the Sun (Henry et al., 2006) at a separation of 4.5 AU (1.170''+-0.003'' on the sky) and fainter by 3.57$\pm$0.057 mag in the 1.575 um SDI filter.We also present high resolution (~0.1''), very high Strehl ratio (0.97+-0.03) mid-infrared (IR) adaptive optics (AO) images of the AGB star RV Boo utilizing the MMT adaptive secondary AO system. RV Boo was observed at a number of wavelengths over two epochs and appeared slightly extended at all wavelengths. With such high Strehls we can achieve super-resolutions of 0.1'' by deconvolving RV Boo with a point-spread function (PSF) derived from an unresolved star.SDI on ground based telescopes provides significant speckle attenuations down to star-planet contrasts of ~1-3x10^4. To test the classical SDI technique at contrasts of 10^6-9, we implemented a similar multiwavelength differential imaging scheme for the JPL High Contrast Imaging Testbed.

Full textAbstract:
L'uomo ha sempre avuto uno stretto rapporto con gli ambienti marini e costieri. La zona costiera è una delle aree più complesse da gestire, costituita sia da ambienti marini che terrestri. Gli ecosistemi marini e costieri sono economicamente e culturalmente importanti per molti paesi, soprattutto per le persone che vivono nei pressi della costa (il 40% della popolazione mondiale vive nel raggio di 100 km dal mare). È anche luogo favorevole ad un crescente numero di attività, diritti e interessi. La popolazione lungo la costa è in costante aumento, determinando pressioni antropiche sul fragile ecosistema della zona costiera.
La necessità di una gestione dell'ambiente dinamico e l'incapacità di integrare le informazioni spaziali marittime e terrestri sono un problema crescente in molte regioni. Lo sviluppo sostenibile delle zone costiere è impossibile senza dati spaziali. L'assenza di un approccio olistico impedisce lo sviluppo sostenibile dell’interfaccia tra l’ambiente marino e terrestre dove tanta pressione e sviluppo sono in corso. Attualmente, la maggior parte delle iniziative per la creazione di una SDI (Infrastruttura di Dati Spaziali) si fermano alla frontiera marina o terrestre del litorale, istituzionalmente e/o spazialmente. Il design della SDI è focalizzato principalmente sull’ accesso e sull’uso di dati relativi al territorio o al mare portando così alla loro duplicazione. Di conseguenza, c'è una mancanza di accesso armonizzato e universale ai dati marittimi, costieri e terrestri. Ciò da origine ad incoerenze nelle politiche di informazione territoriale, nella produzione, nell’accesso e nell’integrazione dei dati.
La creazione di una Infrastruttura di Dati Spaziali (SDI – Spatial Data Infrastructure) per la gestione integrata della zona costiera che copra gli ambienti terrestri e marittimi su base olistica dovrebbe facilitare un più ampio accesso ai dati spaziali e informazioni maggiormente interoperabili attraverso l'interfaccia terra-mare consentendo un approccio più integrato alla gestione delle zone costiere. Una SDI per la Gestione Integrata della Zone Costiera e Marina conduce alla promozione della condivisione dei dati e alla comunicazione tra le organizzazioni facilitando e migliorando il processo decisionale che coinvolge informazioni spaziali marine e costiere.
Lo sviluppo di un modello SDI per la Gestione Integrata della Zona Costiera e Marina e l’implementazione di linee guida si basa sulla ricerca di una teoria e di una pratica relativa agli sviluppi della SDI in tutto il mondo. Un caso di studio (Golfo di Gabes in Tunisia) è stato utilizzato per testare il modello e aiutare nella convalida dei risultati. Lo studio ha dimostrato la difficoltà di integrare dati terrestri, costieri e marittimi e la necessità di una SDI per la Gestione Integrata della Zona Costiera.
I risultati sono un modello SDI e linee guida di implementazione che coprono ambienti sia terrestri che marini e che possono essere utilizzati dagli stakeholders nella zona costiera per creare una piattaforma volta all'utilizzo e alla fornitura di servizi e informazioni spaziali e facilitando così il processo decisionale.Humanity has always had a close relationship with marine and coastal environments. The coastal zone is one of the most complex areas of management in the world consisting of both the marine and terrestrial environments. Marine and coastal ecosystems are economically and culturally important for many countries, especially for people living near coastlines (40% of the world’s population living within 100 km of the sea). It is also a home for an increasing number of activities, rights and interests. Population along the coastline is continuously increasing, bringing about anthropogenic pressures on the fragile ecosystem of the coastal zone. The need to manage the dynamic environment, the inability to integrate marine and land based spatial information is an increasing problem in many regions. Sustainable development of the coastal zone is impossible without spatial data. The absence of a holistic approach prevents the sustainable development of land – marine interface where so much pressure and the development is taking place. Currently, the most SDI initiatives stopping at the land-ward or marine-ward boundary of the coastline, institutionally and/or spatially. SDI design is focused mainly on access to and use of land related datasets or marine related datasets thus leading to data duplication. Consequently, there is a lack of harmonised and universal access to datasets from marine, coastal and land-based. This leads to the creation of inconsistencies in spatial information policies, data creation, data access, and data integration. A Spatial Data Infrastructure for Integrated Costal and Marine Management (SDI-ICMM) covering the land and marine environments on a holistic platform would facilitate greater access to more interoperable spatial data and information across the land-marine interface enabling a more integrated to the management of the coastal zone. SDI-ICMM leads to the promotion of data sharing and communication between organisations thus facilitating better decision-making involving marine and coastal spatial information. The development of an SDI-ICMM model and implementation guidelines has built on the investigation of theory and practice in regards to SDI developments throughout the world. A case study (Gulf of Gabes in Tunisia) has been used to test model and to assist in validating the results. The case study demonstrated the difficulties of integrating terrestrial, coastal and marine data and the need for an SDI-ICMM. The results are an SDI-ICMM model and implementation guidelines that covers both land and marine environments and can be used by stakeholders in the coastal zone to create an enabling platform for the use and delivery of services and spatial information and therefore to facilitate decision-making.

It was shown that resolution is three-dimensional in HD. High HD data rates force the use of video compression in order to transport video. Compression compromises video detail and introduces latency. Latency affects the overlay of time critical measurements. It is therefore important to time stamp at the source. In this volume, the focus is on the key regions of the HD video frame and metadata. SMPTE specifications are the foundation on which MISB builds its use of metadata. It will be shown that only two KLV packets can hold all TSPI and calibration data with frame-by-frame updates. This capacity is new in HD. Metadata is permanently merged with images and the time that both were collected. We show how employing the KLV metadata packet can result in a single video record where picture taking are all in lockstep. Using KLV metadata enables one to record clean video while retaining the ability to place crosshairs and data during playback.

Full textAbstract:
Cette thèse tente de répondre à plusieurs thématiques liées aux aspects socio-économiques des Infrastructures de Données Géo Spatiales (IDGS). Elle met en particulier l’accent sur plusieurs questions concernant leur évaluation économique et la mesure de leurs impacts. Les objectifs peuvent être résumés autour des cinq points suivants: i) proposer un modèle économique pour ce type d’infrastructure afin d’assurer un financement durable; ii) réaliser une évaluation économique de l'information géo-spatiale issue d’une IDGS et disponible via sa plateforme: les images satellitaires à haute résolution spatiale (HR); iii) examiner le rôle d’une IDGS en tant que structure d’information; iv) identifier les impacts économiques d’une IDGS; v) étudier la stabilité de la demande pour l’imagerie satellitaire à travers les IDGS. Afin de répondre à ces interrogations, un premier défi concernait les modèles économiques (au sens de “business model”) dans la mise en œuvre des IDGS. La pertinence d’une approche des marchés biface a été testée via un processus de gestion de plateforme, pour analyser la dynamique d’une IDGS afin d’assurer une transition de l’IDGS vers un mécanisme de financement durable. Un protocole a été élaboré, décrivant la stratégie à travers laquelle une IDGS via sa plateforme, pourrait interagir en permanence entre les différents composants, représentés par les développeurs d’applications basées sur des données spatiales et les utilisateurs potentiels de ces données.Également, il était important d’affiner les questions relatives à l’évaluation des IDGS, en parallèle avec les réflexions sur le modèle économique de ce type d’infrastructure. Dans notre contexte, nous avons examiné la valeur économique des images satellites à haute résolution spatiale (HRS) perçue par les utilisateurs directs d’une IDGS. Les résultats obtenus pourraient être utilisés pour éclairer la conception d’une future tarification de l’imagerie satellitaire, visant à pérenniser le financement de ces services. Dans un troisième temps, nous avons examiné le rôle d’une IDGS en tant que structure d’information. La méthodologie a été appliquée dans le cas de suivi des coupes rases en France. Sur une base d’informations hétérogènes reçues via une multitude de structures d’information, une méthode de prise de décision a été mise en place, afin de fournir à un décideur un outil pour une meilleure prise de décision. Une approche originale a été introduite, en articulant entre deux théories : la méthode classique de Blackwell et la théorie de l’entropie. Le contexte méthodologique se présente suivant deux niveaux : le choix de la structure d’information ayant le pouvoir le plus informatif et la détection de l’action optimale.De même, pour aller plus en détail dans l’identification et l’analyse des impacts socio-économiques d’une IDGS basée sur l’imagerie satellitaire, nous avons considéré l’exemple des coupes rases. Après une analyse des acquisitions d’images satellites pour qualifier le champ des politiques publiques concernées, nous avons étudié la structure des impacts liés à une IDGS. Dans un deuxième temps nous avons évalué quelques-uns de ces impacts d’une manière plus détaillée.Enfin, ces études d’évaluation nous ont mené à examiner la stabilité de la demande d’images via une IDGS. Les IDGS constituent un lien direct entre les utilisateurs de premier rang et la grande industrie spatiale. Elles jouent également un rôle important dans la création d’opportunités de marché. Bien que les utilisateurs soient considérés comme les principaux moteurs de la technologie des données spatiales, ils contribuent à travers leur demande de données et de services au développement et à la croissance de ce domaine. Nous avons abordé la stabilité de différentes demandes d’images satellitaires, et avons fourni des éléments supplémentaires pour une meilleure compréhension de la gestion de ces données, en se basant sur la théorie des RecordsThe development of spatial data infrastructures (SDIs) is hampered by several barriers: form economical, technical to organizational and financial, the hurdles are numerous. This thesis attempts to answer some issues related to the socio-economic aspects of SDIs. It focuses on several topics concerning the SDI economic valuation and impact measurement. The aim has been fivefold: i) to propose a business model for this particular type of infrastructure in order to meet a sustainable financing scheme; ii) to perform an economic valuation of the geospatial information available through the SDI platform, the high resolution (HR) satellite images; iii) to examine the role of a SDI as an information structure; iv) to identify the economic impacts of a SDI; v) to study the stability of the satellite image markets through a SDI.In this thesis, a challenge consisted of approaching the business models field into the implementation of SDIs. The relevance of a two-sided market approach for analyzing a SDI dynamics was tested through a platform management process, in order for a SDI to transition to a self-sustaining funding mechanism. We explained how a SDI through its platform could ensure continuous interaction between the different components, represented by the developers of spatial data applications and the potential users of such data.It was important that the economic valuation questions concerning the SDI, need to be refined in parallel with the reflections about the business model of this type of infrastructure. In our context, we examined the economic value of the HR satellite images as perceived by the direct users of a SDI platform. The valuation study came to assess the importance of the satellite imagery as a support for the territorial planning and development economics. In a context of open and distributed innovation within the networks, it offered elements allowing to establish pricing scenarios on a next level, in order to sustain the SDI platform business model in the long run.In addition, we examined the role of a SDI as an information structure. We applied our findings to the clear-cut forest control case in France. Based on heterogeneous information received, we elaborated a decision-making policy in order to help a decision maker better model his decision. An original approach was introduced, articulating between two existing theories: the classic method of Blackwell and the Entropy theory. We advanced a two-level methodological context: The choice of the information structure with the most informative power and the detection of the optimal action.Similarly, by considering the clear cut example, we analyzed the socio-economic impacts of a SDI based on satellite imagery. A detailed analysis of the geospatial information acquired through the SDI, allowed to characterize the public policies involved in this field, in order to examine the impacts related the SDI ecosystem. In a second step, some of these impacts have been assessed in more details.Finally, these valuation studies opened a window to examine the market demand stability through the SDI. The spatial data infrastructures, which constitute the direct link between the users and the large Earth Observation (EO) industry, have a leading role in establishing market opportunities. While the users are becoming primary key-drivers for spatial data technology, they contribute through their demand of raw data and services, to its development and growth. We approached the stability of different satellite image markets through two independent French SDIs, by using the Records theory. We implemented an innovative method and provided additional elements for a better comprehension of the EO data management

Metadata is an important part of any Spatial Data Infrastructure (SDI). Without proper and sufficient documentation of spatial data, resources are lost when pre-existing data has to be recreated or if data sets overlap. At the same time, creating and updating metadata can be a resource intensive task. Lantmäteriet seeks to optimize the creation and updating of metadata according to the new INSPIRE directive, as well as the Swedish National Geodata Strategy. INSPIRE (Infrastructure for Spatial Information in Europe) seeks to increase cooperation between nations in Europe through harmonization of certain spatial data themes, increased data and software interoperability, as well as the creation of a European spatial data infrastructure. INSPIRE lays the judicial foundation for this European cooperation. Sweden has been involved with INSPIRE since May 15th 2009. This thesis is aimed at developing the most optimal business process model for how the Swedish Mapping, Cadastral, and Land Registration Authority (Lantmäteriet) can create and update metadata according to the new INSPIRE directive based on best practice case studies and extensive literature review. The European Commission (EC) INSPIRE directive will be fully implemented in 2010. Furthermore, a survey of current metadata practices has been carried out to establish a starting off point for metadata creation at Lantmäteriet as well as a best practice business process model using ArcGIS Desktop.

Cette étude s’intéresse à la participation interactionnelle d’un enfant avec autisme sans déficience intellectuelle (SDI) associée, d’âge préscolaire - l’âge où il bénéficie d’interventions comportementales précoces tout en étant intégré dans un milieu éducatif de la petite enfance. Dans un premier temps, le recours aux méthodologies d’inspiration ethnographique a permis de dresser un portrait de l’ensemble échanges de tutelle qu’il engage avec les adultes qui lui sont proches. Ainsi, l’étude soulève que cet enfant participe lui aussi à une grande variété d’échanges, qui sont réglés par des attentes et conventions conversationnelles parfois opposées. Dans un deuxième temps, l’analyse interactionnelle met en discours les compétences conversationnellesde l’enfant et les efforts d’étayage de ses parents ou intervenantes pour maintenir et poursuivre l’échange. L’analyse débouche sur trois saynètes de participation – ouverte, guidée ou fermée – au sein desquelles varient les étayages de l’adulte, les compétences et conduites autistiques de l’enfant et, plus largement, les objectifs d’apprentissage. Pour conclure, l’étude discute la pertinence des différentes interventions rééducatives dans l’objectif de préparer cet enfant avec autisme à l’intégration en milieu préscolaire régulierThis research study focuses upon the interactional participation of a child with high functioning autism at an age where he is receiving early intensive behavioural interventions and is integrated into an early childhood environment. The study’s adoptionof an ethnographic-influenced methodology has made it possible to capture the full range of exchanges between the child and key adults. This approach furthermore highlights the child’s participation in a wide variety of exchanges that are regulated by various expectations and conversational conventions. At the same time, the study’s interactionist analysis calls attention to the conversational competencies of the child, as well as the scaffolding efforts of his parents and his therapists to maintain and pursue the exchanges. The analysis makes visible three participatory scenes, open, guided and closed, within which the adults’ scaffolding varies, the competencies of the child vary, and, more broadly, the learning objectives vary. In conclusion, the study discusses the appropriateness of different therapeutic interventions aimed at preparing the observed child with autism for integration into a regular preschool setting

Full textAbstract:
En mängd forskning har gjorts kring kvinnors hinder att nå chefspositioner och vilka fördomar kvinnliga chefer möter. Många studier visar att fördomar bottnar i bristande överensstämmelse mellan den kvinnliga könsrollen och ledarskapsrollen. Syftet med studien (n = 683) var att undersöka attityder till ledarskap och jämföra hur män och kvinnor inom två könssegregerade yrkesgrupper, sjuksköterskor och poliser, attribuerar manliga respektive kvinnliga egenskaper till ledaregenskaper. Hypoteserna baserades bland annat
på social identitetsteori. Resultatet visade att bägge yrkesgrupper förknippade framgångsrikt ledarskap med både kvinnliga och manliga egenskaper. Dock var sjuksköterskors skattning av kvinnliga egenskaper kontra ledaregenskaper högre än deras skattning av manliga egenskaper i förhållande till ledaregenskaper. Signifikant högre grad av fördomsbenägenhet gentemot kvinnliga ledare kunde påvisas bland poliserna.
It has been shown that barriers and prejudice’s impede women’s progress to managerial levels. Studies show that prejudice’s derives from perceived sextyping of the managerial role. The aim of the present (n = 683) study was to examine attitudes towards leadership and compare how men and women within two gender segregated occupational groups, nurses and polices, attributes male and female characteristics to successful management. The hypotheses were based on social identity theory. Results revealed that both occupational groups associate successful management with both male and female characteristics. However, nurses’ valuation of female characteristics counter managerial characteristics was higher than their valuation of male characteristics versus managerial characteristics. A significant higher level of prejudice towards female leaders was found among polices.

Orientador: Gilberto Pechoto de MeloResumo: A identificação de trincas ainda é um desafio na área de monitoramento da integridade estrutural em eixos rotativos. Embora muitas técnicas e modelos tenham sido desenvolvidos, encontrar uma técnica eficiente que possa localizar uma única ou múltiplas trincas ao longo do eixo, ainda é um grande desafio. Nesse trabalho, um novo índice para localização de trincas em eixos rotativos é apresentado. A equação do movimento do rotor com trinca utiliza a notação em coordenadas complexas a fim de separar as contribuições dos modos de precessão direta e retrógrada. O índice SDI (shape and directivity index) é calculado para o rotor, cujo modelo matemático considera a variação instantânea da rigidez do elemento finito devido à abertura e o fechamento gradual da trinca, conhecido como efeito breathing. Através da manipulação do SDI no modelo de cores HSV (hue, saturation and value), desenvolve-se uma escala métrica, visualizada em um mapa de cores, que possibilita localizar a anisotropia causada pela trinca ao longo do eixo. Profundidade e posição da trinca, presença de múltiplas trincas, entre outros fatores que afetam a assinatura da trinca em outros métodos de identificação são analisados. Bons resultados demonstram a eficiência e robustez do novo índice para diversos casos de operação do rotor. Essa métrica de dano acrescenta uma contribuição para os métodos de localização de trincas em sistemas rotativos.
Abstract: Crack identification is still a challenge in the area of structural health monitoring dedicated to rotating shafts. Although many techniques and models have been developed, finding an efficient technique capable of locating a single or multiple cracks along the shaft is still a challenge. In this work, a new index for locating cracks in rotating shafts is proposed. The equation of motion of the cracked rotor uses notation in complex coordinates in order to separate the contributions of forward and backward precession modes. The SDI (shape and directivity index) is calculated for the cracked rotor, which mathematical model considers the instantaneous variation of the finite element stiffness due to the gradual opening and closing of the crack, known as the breathing effect. By manipulating the SDI in the HSV (hue, saturation and value) color model, a metric scale is developed to locate the anisotropy caused by cracks along the shaft, visualized on a color map. Depth and position of the crack, presence of multiple cracks, among other factors that affect the signature of the crack in other identification methods are analyzed. Good results demonstrate the efficiency and robustness of the new index for several rotor operation conditions. This damage metric contributes to crack localization methods in rotating systems.

Full textAbstract:
The ever increasing demand of our information society for reliable Geographic Information (GI) is the moving power for the development and maintenance of Spatial Data Infrastructures (SDI). Consequently, an SDI works to full benefit of its users if the SDI data collection is accessible and can be efficiently used by all users in spatial problem solving and decision-making. Current development and use of SDI focuses on handling geospatial data entirely by means of information technology. Thereby, low awareness seems to be paid to a user-friendly and understandable presentation of geospatial data.
Based on the understanding that GI is the result of human geospatial information processing, it is argued that cartography is essential in the SDI context in order to achieve the objectives of SDI. Specifically, the thesis aimed at exploring the concept of user-oriented map design in relation to SDI and elaborating a methodology for creating effective cartographic representations for SDI relevant user types.
First of all, the SDI concept, its objectives and principles are explored using the example of the current European SDI initiatives as to the human aspect of an SDI. Secondly, in order to determine the role and task of cartography in the SDI context, the conceptual framework of contemporary cartography is reviewed to provide the theoretical and technological framework for a user-oriented map design. Given this, the SDI environment is assessed in relation to cartography with respect to the services providing access to the SDI data collection. Further, an SDI map production framework is elaborated utilising Spiess’ concept of the graphic filter as a model for the transformation of SDI data into useful cartographic representations. Besides, the map design strategy by Grünreich provides the starting point for developing the process of map production. The main tasks are detailed and justified taking into consideration the semiotic-cognitive and action-related concepts underpinning contemporary cartography. The applied research encompasses a case study which is performed to implement and, thus, evaluate the proposed methodology. It starts from a use case scenario where an international spatial planning team requires getting familiar with the overall geographic characteristics of a European cross-border area. Following the process steps of user-oriented map design in the SDI environment, a map design specification is elaborated and implemented under real world conditions.
The elaborated methodology for creating user-friendly and understandable cartographic representations of geospatial data in the SDI environment is based on theoretical and technological foundation of contemporary cartography. Map design in the SDI context, first of all, means to establish a graphic filter that determines the parameters and rules of the cartographic transformation process to be applied. As both an applied art and engineering the design of the graphic filter is a creative process developing a map design solution which enables SDI users to easily produce their map. It requires on the one hand an understanding of map use, map user and map use situation, and on the other hand insight into the data used as the source. The case study proves that the elaborated methodology is practicable and functional. Cartographic reverse engineering provides a systematic and pragmatic approach to the cartographic design task. This way, map design solutions can be built upon existing cartographic experience and common traditions as suggested by the INSPIRE recommendation for portrayal. The resulting design solution constitutes a prototype of a European Reference Map at medium scale built upon existing cartographic experience and common traditions. A user-friendly, understandable and comparable presentation of geospatial data in Europe would support the human and institutional potential for cross-border cooperation and collaboration. Besides that, the test implementation shows that tools are available which make it technically feasible and viable to produce a map from geospatial data in the SDI data collection.
The research project raises awareness to the human aspect of SDI inherit in its objective to support end users to derive GI and knowledge from the geospatial data gathered in the SDI data collection. The role and task of cartography in the SDI context is to contribute to the initiation, creation, and maintenance of portrayal services to facilitate a comprehensive access to the underlying geospatial data by means of a user-friendly and understandable graphic interface. For cartography to take effect in the SDI development and use, cartographic design knowledge has to be made explicit and operational. It is the responsibility of cartographic professionals to prepare the map design. The wide range of map use contexts requires a great flexibility of design variants depending on the dimension of human-map interaction. Therefore, the design of the maps needs to be user-driven to enable an efficient map use in the user’s task. Besides their function as a graphic interface, maps facilitate a common understanding of the depicted geographic features and phenomena when sharing GI between SDI users. In other words, map design can be regarded a measure to establish interoperability of geospatial data beyond the technical level. The research work is in the scope of communication cartography, a research domain seeking to deepen the understanding of the role of cartographic expressions when understanding and communication of GI is involved.Der wachsende Bedarf unserer Wissensgesellschaft an zuverlässigen Informationen über räumliche Strukturen und Sachverhalte ist die treibende Kraft bei Aufbau und Einsatz von Geodateninfrastrukturen (GDI). Eine Geodateninfrastruktur wirkt zum vollen Nutzen der Gesellschaft, wenn die Daten in der GDI zugänglich sind und effektiv für Erkenntnis- und Entscheidungsprozesse genutzt werden können. Die gegenwärtige Entwicklung von GDI setzt auf moderne Informationstechnologien bei der Geodatenverarbeitung. Dabei, wird einer bedarfsgerechten und nutzerfreundlichen Präsentation von Geodaten in ansprechender visueller Form wenig Aufmerksamkeit zuteil. Da Geoinformation erst durch die Interaktion des Nutzers mit den Geodaten entsteht, ist es Aufgabe der Kartographie, bedarfsgerechte Kartendarstellungen zu gestalten und an der Schnittstelle zwischen einer Geodateninfrastruktur und ihren Nutzern bereitzustellen. Ziel der vorliegenden Dissertation ist es, eine Methodik für den Kartenherstellungsprozess in einer GDI-Umgebung zu entwickeln und beispielhaft zu erproben. Zunächst, werden Konzept, Ziele und Prinzipien von Geodateninfrastruktur beispielhaft anhand der Europäischen GDI-Initiativen dargestellt und hinsichtlich des Bedarfs an kartographischen Darstellungen untersucht. Danach wird, ausgehend von der Forderung nach verständlichen und gut interpretierbaren Geoinformationen, die Rolle der Kartographie im GDI-Kontext bestimmt. Dabei werden zunächst Funktion und Aufgaben der Kartographie sowie die tragenden Konzepte und Grundlagen einer nutzerorientierten Kartengestaltung dargelegt. Der Vergleich der bestehenden Geodatenzugangsdienste zur Funktion der Kartographie ergibt eine Lücke, die es zu schließen gilt, um den Nutzeranforderungen gerecht zu werden. Dazu wird der Gesamtprozess für die Herstellung von Karten im GDI-Kontext beschrieben. In diesem Prozess kommt dem Graphikfilter von Spiess (2003) besondere Bedeutung als Modell eines wissensbasierten Systems zur Aufstellung und Umsetzung von kartographischen Gestaltungsregeln zu. Den Ausgangspunkt für die Ausarbeitung der Teilprozesse bieten die von Grünreich (2008) vorgeschlagenen Teilaufgaben der Kartographie im Rahmen der GDI. Mittels eines Anwendungsfalls im Europäischen Kontext wird der vorgeschlagene Gesamtprozess erprobt. Dieses Beispiel geht davon aus, dass eine internationale Planungsgruppe im Zuge der Konzeption einer grenzüberschreitenden Verkehrsverbindung eine anschauliche Beschreibung der Landschaft in Form einer einheitlich gestalteten und flächendeckenden Karte benötigt. Durch Anwendung des kartographischen Reverse Engineering anerkannt gut gestalteter Karten werden die Vorgaben für die Kartengestaltung ermittelt. Einschließlich der Anwendung auf konkrete GDI-Daten wird der zuvor entwickelte Herstellungsprozess ausgeführt und diskutiert. Die entwickelte Methodik für den Kartenherstellungsprozess in der GDI-Umgebung basiert auf den semiotisch-kognitiven und handlungstheoretischen Konzepten der modernen Kartographie. Kartengestaltung im Kontext von Geodateninfrastrukturen bedeutet die Entwicklung eines Graphikfilters, der eine optimale bedarfsgerechte Visualisierung der Geodaten mittels nutzerspezifischer Parameter und Gestaltungsregeln ermöglicht. Wie das Fallbeispiel zeigt, ist es die durch die entwickelte Methodik möglich, brauchbare und nützliche Kartendarstellungen zu gestalten. Die Anwendung des kartographischen Reverse Engineering erlaubt es, Kartendarstellungen zu entwickeln, die - wie von INSPIRE empfohlen - bewährten kartographischen Erfahrungen und allgemeinen Traditionen entsprechen. Das Ergebnis des Anwendungsfalls ist ein Prototyp einer Europäischen Referenzkarte im Maßstab 1: 250,000. Die einheitliche und somit vergleichbare Darstellung über Grenzen hinweg unterstützt das Planungsteam in seiner Arbeit. Die praktische Umsetzung der Karte zeigt zudem, dass funktionsfähige Werkzeuge und Technologien für die regelbasierte Kartenherstellung aus GDI-Daten vorhanden sind. Die Dissertation trägt dazu bei, das Bewusstsein für den menschlichen Aspekt der Nutzung einer Geodateninfrastruktur zu schärfen. Der Beitrag der Kartographie zur Nutzung der Geodaten einer GDI besteht in der Initiierung, Gestaltung und Pflege von Darstellungsdiensten, da die Nutzbarkeit der Geodaten am besten gewährleistet ist, wenn die Gestaltungsmethoden der Kartographie angewendet werden. Dabei liegt es in der Verantwortung der Kartographen, die nutzerseitigen Aspekte dieser graphischen Schnittstelle unter Berücksichtigung der modernen kartographischen Konzepte zu betreuen. Gemäß INSPIRE-Richtlinie werden auf Karten gestützte Informationen bei zahlreichen Tätigkeiten verwendet. Für eine effektive visuelle Informationsverarbeitung durch den Nutzer ist daher eine nutzerorientierte Kartengestaltung in Abhängigkeit von der geplanten Interaktion (z.B. Kommunikation oder Analyse) unerlässlich. Neben der Funktion als Schnittstelle machen kartographische Darstellungen räumliche Strukturen verständlich. Daher ist die Kartenherstellung im GDI-Kontext eine Maßnahme, um Interoperabilität von Geodaten über die technische Ebene hinaus auf menschlicher Ebene zu ermöglichen. Die Relevanz dieser Forschungsarbeit liegt im Bereich der Kommunikationskartographie, die die Effektivität und Verbindlichkeit der Kommunikation über räumliche Strukturen und Sachverhalte zu vertiefen sucht.

Full textAbstract:
This thesis investigates the problems associated with the development of Spatial Data Infrastructures (SDIs). The results of this investigation are used as input for the development of new spatial data policy strategies for individual organisations to enable an improved better facilitation of SDIs. Policy issues that need to be considered by an organisation when developing spatial data policies, were identified as being: SDI requirements; organisational issues; technical issues; Governmental/organisational duties; ownership/custodianship; privacy and confidentiality; legal liability, contracts and licences; Intellectual Property Law; economic analysis; data management; outreach, cooperation and political mandate; and users' choices, rights and obligations. In order to gain an understanding of current spatial data policy practices and to device new policy strategies a spatial data survey was conducted. This survey addressed the identified SDI problem areas. Some 6630 questionnaires were mailed out with more than 400 responses returned. These were reduced to 379 useful responses. Once analysed, the results were compared with the findings of the SDI investigation and used throughout the thesis. The results of the analysis to the spatial data survey are displayed in tables and graphs throughout Chapters 3, 4, 5 and 6 and in Appendix 2. The tables and graphs show the answers to the questions asked in the questionnaire as a percentage of the total number of respondents. The survey discovered that many organisations had no spatial data policies, nor individual policies on spatial data pricing and/or intellectual property protection. This thesis established that SDI requirements are not being met by many spatial data policies used by individual organisations. Hence, the thesis studied the spatial data policy issues that are involved when an organisation develops new policies with the aim to aid the development of SDIs. It uniquely established current Australian spatial data policy practices in the areas of spatial data quality, access, pricing, and legal issues to form the basis for future strategies. It reviewed the current knowledge of intellectual property law applied to spatial data and devised new approaches to deal with all the identified policy issues. Finally, the thesis defines spatial data policies that facilitate SDI development.

Full textAbstract:
This thesis seeks to understand collective practices of urban grassroots, rationalities behind the practices and their potential role in urban politics. The study used insurgent planning and co-production frameworks to highlight practices of the studied organization and adopted theories about relationship between the local and the global. The thesis addressed questions about collective practices for building self-reliance, practices that aim to directly engage the state and how being part of an international network of slum dwellers shapes the collective practices of the local organization. The research is based upon a case study of Zambian Homeless and Poor People’s Federation. The empirical data was collected during two months of fieldwork in Zambia using observations and semi-structured interviews. The results indicate that the studied organization uses elements of both insurgent planning and co-production in its practices. The federation starts with self-help and building financial assets to continue with practices aimed at engaging the state. The results suggest that, as an affiliate of an international network, the federation is influenced by the flow of ideas in the network and that the international cooperation has potential implications for the local urban politics.

there is still low availability of georreferenced data about the Amazon. The goal of the present
work is the development of a spatial data infrastructure (SDI), that is, an environment of
sharing and use of georreferenced data based on the technology of web services, metadata and
interfaces that allow the user easy access to these data. The present work discussess the OGC
patterns, the most relevant georeferrenced data servers, the main web clients, and the
revolution in the dissemination of georeferrenced data which geobrowsers and web clients
offered to regular users. Data to be released for the case study come from the project
Exploitation of Non-wooden Forest Products-PFNM-in progress at the National Institute of
Research in the Amazon-INPA-as well as from inventories of NGOs and other government
bodies. Besides contributing to the enhancement of PFNM, this project aims at encouraging
the use of GIS in the state of Amazonas offering tech support for the deployment of
geographic databases and sharing between agencies, optimizing the resources applied in this
area through the use of free software and integration of diffuse information currently
available.

L’obiettivo del progetto di ricerca è creare una metodologia per ricercare, archiviare e diffondere dati glaciologici partendo dallo sviluppo di una infrastruttura di dati spaziali (SDI) che possa essere utile allo studio dell’evoluzione glaciale in relazione ai cambiamenti climatici. Questa ricerca è parte del progetto di interesse nazionale NextData (www.nextdataproject.it). Nei primi due anni è stato sviluppato un geodatabase contenente dati riguardanti la caratterizzazione chimico-fisica di carote di ghiaccio. La prima versione del geodb presentava delle criticità che sono state superate con l’implementazione della seconda versione dove sono stati applicati i seguenti miglioramenti: Sviluppata e applicata una metodologia di riposizionamento, aggiunta di differenti entità con informazioni riguardanti il progetto di perforazione, il sito di perforazione, le references dei dati e tutte le informazioni aggiuntive utili per la classificazione e la caratterizzazione delle ice cores. Durante il terzo anno di ricerca alla nuova struttura creata e chiamata IDB2 sono stati uniti diversi database glaciologici contenenti dati spaziali, geomorfometrici e informazioni su ghiacciai. E’ stata sviluppata una nuova parte dell’infrastruttura capace di accogliere dati derivanti da analisi geomorfologiche, nello specifico sono state aggiunte due entità chiamate rispettivamente Glacier_code_tab e Glacier_data_tab. La prima archivia l’unione tra differenti banche dati glaciologiche. Nello specifico gli ID del GLIMS, RGI, WGI, WGMS sono stati aggiunti e collegati ad ogni ghiacciaio perforato. La seconda contiene dati geomorfologici calcolati tramite un algoritmo GIS sviluppato durante il terzo anno. L’algoritmo sviluppato in ambiente GIS è stato chiamato GLACIER DATA MODULE (GDM). L’algoritmo è stato sviluppato per poter ricavare informazioni dettagliate per la calibrazione dei Minimal glacier model (MGM), una famiglia di modelli glaciologici per la predizione dell’andamento dei ghiacciai in risposta alle fluttuazioni climatiche. La procedura richiede per ogni ghiacciaio come input DTM, poligoni riportanti il confine glaciale e le linee di flusso del ghiaccio. Queste ultime sono state calcolate partendo dal risultato dell’algoritmo r.flow e dopo un attenta analisi geomorfologica è stata individuata la flow line principale del ghiacciaio analizzato. L’algoritmo è stato applicato a 34 ghiacciai della catena alpina con le più lunghe misurazione di bilanci di massa, parametro fondamentale per la calibrazione dei MGM. I dati di input per l’algoritmo sono stati ricavati dalla SDI IDB2 e come DTM è stato usato ASTER GDEMv2. I risultati del GDM sono stati usati per popolare IDB2 chiudendo così l’iteratività della SDI creata e sono stati usati per calibrare i MGM utili a valutare la risposta dei ghiacciai ai cambiamenti climatici. I dati geomorfologici ricavati dall’analisi spaziale sui ghiacciai sono anche stati usati per definire degli andamenti utili a definire la distribuzione dei ghiacci alpini lungo la catena montuosa.
Per concludere la creazione della SDI, un geoportale è stato sviluppato ed è disponibile al sito: http://geomatic.disat.unimib.it/home/geomatic/idb2/.
Concludendo, durante il mio dottorato ho sviluppato una SDI contenente dati glaciologici. La struttura ha permesso fino ad oggi di modellare la suscettibilità di ghiacciai non polari alla perforazione e di calibrare modelli glaciologici semplici come i MGM utilizzati per valutare la risposta dei ghiacciai ai cambiamenti climatici. La struttura verrà usata in futuro come base per lo sviluppo di banca dati riguardate tutti i proxy paleoclimatici utili alla ricostruzione del clima nella penisola italiana degli ultimi 2k anni.The aim of my Ph.D. research is to create a methodology for recovery, storage, access and disseminate glaciological data, starting from the development of a spatial data infrastructure (SDI) and use it to study the evolution of the glaciers in relation with climate change. My research is part of the project of interest Nextdata (www.nextdataproject.it). In the first two years a geodatabase for glaciological data was built. A new structure that can contain data about world non polar ice core characterization (IDB1) was implemented. To overlap IDB1 critical issues a new structure was set-up with this improvements: A repositioning methodology was set-up to increase the accuracy of coordinates of the ice cores, different entities with information about project of perforation, drilling-site, references of data and additional information about ice core were added to the structure. During the third year of research the new geodatabase IDB2 was linked with glaciological databases of glaciers containing spatial, geomorphometric and other information. A new part was developed to store data coming from geomorphological analysis. In particular two entities about glaciers were added: the first, Glacier_Code_tab stores the union between the different glaciers databases such as GLIMS, RGI, WGI, WGMS id for each perforated or not perforated glaciers. The second one, Glacier_Data_Tab contains the geomorphological parameters such as Flow line length, min and max elevation, averaged slope and aspect calculate using a GIS algorithm developed. A GIS module called GlacierDataModule (GDM) was developed also during the third year to provide detailed information to calibrate minimal glacier model (MGM) to assess glaciers response to climatic fluctuations and to linkage the geomorphological parameters with climate variability. The procedure requires for each glacier, as inputs DTMs, POLYGONs and FLOW LINEs. The flow lines was calculated starting from the results of r.flow algorithms and after a subjective evaluation based on morphological parameters the most important flow lines were digitalized. The algorithm was applied at 34 glaciers of great alpine region (GAR) that are the glaciers with the longest measurements of mass balance, the primary data needed to run the minimal model. Input data required to GDM were recovered from IDB2 and ASTER GDEMv2 was used as DEM input source. Results of GDM on GAR was used to populate IDB2 in an iterative way and used to calibrate the MGM to assess glaciers response to climatic fluctuations. Geomorphological data coming from the spatial analysis on glaciers was also used to compare the glaciers and find some behaviour useful to evaluate the glacier distribution along the GAR. The results of this analysis shows a clear climatic characteristic of the glaciers of GAR. Only 34 glaciers was evaluated but the results was comparable to the results presents by Evans in his study where 6561 glaciers on GAR were taken in account (Evans, I.S., 2006). A geoportal with a webgis available at: http://geomatic.disat.unimib.it/home/geomatic/idb2/ was developed to share this data. In conclusion during my Ph.D. a SDI contain glaciological data was set-up, drawn and implemented. SDI allowed until now at the scientific community to modelling the suitability for ice core drilling of mountains glaciers and provide a input parameters to run a GIS module developed. GIS Module is used to obtain geomorphological parameters to calibrate minimal model, evaluate the glaciers response at climatic fluctuations through the glacier distribution along the GAR. The IDB2 will be also used in the future to identify paleo-climatic proxy that could be useful, within the interaction of other paleo-climatic proxies (lake sediments; marine sediments; pollen and corals), to reconstruct the last 2K years of climate variability in Italy.

Spatial information is increasingly acknowledged as a national resource essential for sustainable development. Spatial Data Infrastructure (SDI) is part of the basic infrastructure that needs to be efficiently coordinated and managed in the interests of the nation. However, there is no framework or adequate knowledge available for users, providers and administrators of SDI to collaborate effectively to build National SDI. In countries that are a federation of states, administration is dispersed across multiple tiers of government.

Full textAbstract:
This Master thesis is written in the field of collaborative planning aiming to challenge the collaborative approach on it applicability, especially in the context of the Global South. As a case study it looks on the urban poor community participatory practice, the so called 're-blocking' in Cape Town – an example of insitu informal settlement upgrading. It questions not only to what extent re-blocking displays a successful approach of collaborative planing but also whether it can lead to more inclusive cities in South Africa. The field data was gained through qualitative semi-structured interviews, observations and an analysis of national housing policy documents. The findings evaluate re-blocking as a successful example of collaborative planning in the sense that local communities are truly involved in the process and have a lot of decision making power. Also, re- blocking can be replicable to other cities in South Africa. Yet it faces several risks in community mobilisation and communication and can only be operated on a small scale. Therefore, the thesis concludes that re-blocking itself may not lead to inclusive cities, however as an example of community participation it may change the mindset of the South African society and (local) government towards informal community inclusion.

Full textAbstract:
Notre sujet de thèse s’inscrit dans un projet de recherche dont le promoteur est le CHU de Montpellier, sous la responsabilité du Pr. BAGHDADLI : la validation de la version française de l’échelle RAADS-R (Ritvo Autism Asperger Diagnostic Scale-Revised), outil d’aide au diagnostic pour les formes légères de trouble du spectre autistique chez l’adulte (autiste de haut niveau, sans déficience intellectuelle). Dans ses recommandations de Juin 2011 sur les Troubles du Spectre Autistique (TSA), la Haute Autorité en Santé (la HAS) demande qu’un effort particulier soit mené sur le dépistage et la prise en charge des patients adultes, avec pour objectif d'améliorer le repérage des troubles. Il existe actuellement plusieurs échelles en langue anglaise utilisables pour le repérage diagnostic des patients autistes de haut niveau. L’une d’elle, la Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R), est un questionnaire d’auto-évaluation conçu pour être rapide et facile à administrer, particulièrement pratique. Déjà validée en langue anglaise (Ritvo et al., 2010), elle vise à identifier les formes légères de TSA chez les personnes adultes et constitue une aide au diagnostic. L’objectif de la recherche est la validation de la version de cette échelle déjà traduite en français : validation complète, psychométrique et diagnostique, via la comparaison entre trois types de population (groupes de personnes porteuses de TSA, groupes avec d’autres troubles, et groupe sans trouble). L’intérêt clinique de cette validation est la diffusion d’un nouvel outil permettant aux services accueillant des patients jeunes adultes et adultes de repérer plus efficacement ceux porteurs d’un TSA de forme légère et de leur offrir par conséquent les prises en charge adéquates. Plusieurs études ont en effet identifié chez l’adulte des chevauchements importants concernant la symptomatologie des TSA de forme légère (autisme de haut niveau) et celle d’autres troubles faisant partie des comorbidités (Barneveld et al., 2011; Cath & al., 2008), ce qui rend le dépistage plus difficile et montre la nécessité d’un outil correctement discriminant. Par ailleurs, cette échelle permettra de venir enrichir les quelques outils disponibles permettant d’aider au diagnostic chez l’adulte, la HAS en retenant seulement trois pour l’instant : l’Autism Diagnostic Observation Schedule-Generic (ADOS-G module 4), l’ADI-R (Autism Diagnostic Interview- Revised) et l’EC2R (Echelle des Comportements Restreints et Répétitifs). La RAADS-R validée en Français sera en outre la seule échelle francophone permettant une aide au diagnostic des personnes adultes avec autisme de haut niveau. Enfin, cet outil validé devrait permettre aussi d’aider à constituer des échantillons de population et d’aider ainsi à développer la recherche sur les TSA chez l’adulte, domaine encore peu exploréThe body of knowledge regarding autism spectrum adults with no Intellectual Disability (ASD No ID) is still limited. Therefore, the clinical profile and the socio-demographic (SD) profile of a French study sample are explored here, according to the following variables: sex, age and nonverbal cognitive level (NVIQ) in adulthood; as well as for the SD profile, age of diagnosis and intensity of ASD symptoms in adulthood. The frequency of clinical difficulties and SD data are also compared to those of a non-clinical group (NC) and a group with other disorders. The results have implications in terms of diagnostic identification and care

Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2006.A Synchronous Digital Hierarchy (SDH) point-to-point bi-directional link was implemented at a base Synchronous Transfer Mode level 1 (STM 1) signal rate. The full STM-1 multiplexer was implemented and the functional code developed to Virtual Container level 4 (VC4) level. The implementation was realized using a Software Defined Radio (SDR) architecture that managed and linked the SDH atomic units into a STM-1 SDH multiplexing structure. These atomic units have been well defined in recommendation G.707 [1]. The functional description of each unit was based on the G.783 [8] recommendation which specifies a library of basic building blocks and set of rules by which these atomic functions should be combined into various functional layers. These layers interconnect to ultimately form a bi-directional path in the SDH network. A SDH Management Sub network (SMS) was implemented using a graphical user interface to perform a monitoring function for the bi-directional link.

Full textAbstract:
Questo lavoro ha avuto come obiettivo quello di indagare, tramite lo studio di articoli della letteratura, il ruolo funzionale che riveste il ritmo cerebrale alpha (8-13 Hz) nei processi cognitivi quali attenzione, memoria ed elaborazione di emozioni, ed analizzare come anomalie nell’attività di questo ritmo possano essere associate a diverse patologie neurologiche. Il ritmo alpha sembra avere un ruolo inibitorio: la sincronizzazione delle oscillazioni (ERS) in questo range di frequenze equivale ad una diminuzione dell’attivazione corticale, mentre una desincronizzazione delle oscillazioni (ERD) corrisponde ad una maggiore attivazione corticale. Nello svolgimento di task attentivi e mnemonici, una buona performance è legata alla presenza di ERD in banda alpha nelle regioni corticali rilevanti per il compito, mentre si ha ERS nelle regioni non rilevanti e potenzialmente interferenti, in modo da bloccare l’elaborazione e l’afflusso di informazioni distraenti. In aggiunta, l’asimmetria frontale alpha (FAA) è un parametro analizzato nello studio dell’elaborazione delle emozioni, in quanto uno sbilanciamento nell’attivazione dei due emisferi è responsabile delle differenze interindividuali nella reazione a stimoli emotivi, essendo la corteccia prefrontale sinistra più coinvolta nell’elaborazione di stimoli positivi mentre la destra di stimoli negativi. Anomalie nel ritmo alpha si ritrovano in diverse malattie neurologiche; questo elaborato tratta del disturbo depressivo maggiore, disturbo bipolare e morbo di Alzheimer. Il disturbo depressivo comporta un’attività maggiore in banda alpha nella corteccia frontale sinistra rispetto alla destra, mentre nella zona posteriore si riscontra un’asimmetria opposta. Nel caso del disturbo bipolare poi, i pazienti hanno una notevole riduzione di potenza alpha rispetto a soggetti sani. Infine, individui affetti da morbo di Alzheimer mostrano un decremento dell’attività in banda alpha, insieme ad una diminuzione della coerenza.

La tesi è suddivisa in tre parti. Nella prima parte si descrive il sistema dei canali bolognesi che derivano acqua dal bacino montano del Fiume Reno e dal Torrente Savena, e il sistema di gestione e di monitoraggio utilizzato dal Consorzio dei canali di Reno e Savena. Nella seconda parte si illustra una proposta di sistema di visualizzazione dei dati idro-pluviometrici che si sta valutando, assieme al Presidente del Consorzio e ad Arpa, per il monitor che il Consorzio intende installare al fine di illustrare al pubblico il monitoraggio e l’evoluzione degli eventi di piena e di scarsità idrica/siccità. Nella terza parte, infine, si effettuano la stima e un’analisi della correlazione tra due diversi indici di siccità, meteorologica ed idrologica, per il bacino del Reno chiuso a Casalecchio.
Il sistema dell’intero bacino del Reno e della rete dei canali cittadini risulta molto complesso. Vista tale complessità del sistema, si è proposto di distinguere uno scenario di piena e uno scenario di magra. Tra le diverse informazioni da visualizzare nel monitor si intendono anche visualizzare informazioni relative alla disponibilità idrica alla scala del bacino in esame. Per questo è stata svolta l’analisi sugli indici di siccità Standard Precipitation Index (SPI) e Streamflow Drought Index per il bacino del Reno chiuso a Casalecchio . Tali indici hanno portato a dei risultati consistenti con le condizioni idro-metereologiche e con le informazioni sugli impatti al suolo disponibili per alcuni degli eventi più significativi presi in esame. In base ai risultati ottenuti è possibile affermare che gli indici SPI e SDI a scala di bacino hanno una buona correlazione che permette di poter considerare anche la sola caratterizzazione pluviometrica per identificare la situazione della disponibilità idrica del fiume a monte dell’opera di presa del Canale di Reno.

Full textAbstract:
Optical networking has been developing for decades and wavelength-division multiplexing (WDM) is the main technology used to carry signals in fiber-optical communication systems. However, its development has slowed because it is approaching the Shannon limit of nonlinear fiber transmission. Researchers are looking for multi dimensional multiplexing. Space-division multiplexing (SDM) is an ideal way to scale network capacities. The capacity of WDM/SDM network could be expanded to several times the capacity of WDM network but the active hardware devices may also increase by several times. This project aims to answer a practical question: How to construct a WDM/SDM network with less hardware resource? There is no mature research about WDM/SDM network yet. Therefore, the problem can be divided into two parts: (1) how to build a WDM/SDM network and (2) how to allocate resource and compute routes in such a network to minimize hardware resources. First, this thesis proposes a WDM/SDM node which has bypass connections between different fibers and architecture on demand (AoD) to effectively decrease the number of active hardware devices within the node. Then, two types of networks were constructed: one with bypass connections in each node and another one without any bypass connections. These networks were under the control of a software defined network (SDN) controller. The controller knew the wavelength resources within the networks. Several algorithms were applied to these networks to evaluate the effect of a bypass network and to identify the desired characteristics (to find short length path and decrease the probability of spectrum fragmentation) of an algorithm suitable for a network with bypass connections. The results of applying the proposed algorithms in two networks proved that the bypass connections increased the blocking probability in small topology but did not affect the results in large topology. The results in a large-scale network with bypass network were almost the same as the results in a network without bypass connections. Thus, bypass connections are suitable for large-scale network.Optiskt nätverk har utvecklats i årtionden och våglängdsdelningsmultiplexering (WDM) är den viktigaste tekniken som används för att bära signaler i fiberoptiska kommunikationssystem. Utvecklingen har dock minskat eftersom den närmar sig Shannon-gränsen för olinjär fiberöverföring. Forskare letar efter flerdimensionell multiplexering. Space-division multiplexing (SDM) är ett idealiskt sätt att skala nätverkskapacitet. Kapaciteten för WDM / SDM-nätverk kan utökas till flera gånger WDM-nätverkets kapacitet, men de aktiva hårdvaraenheterna kan också öka med flera gånger. Projektet syftar till att svara på en praktisk fråga: Hur konstruerar jag ett WDM / SDM-nätverk med mindre hårdvara? Det finns ingen mogen forskning om WDM / SDM-nätverk än. Därför kan problemet delas in i två delar: (1) hur man bygger ett WDM / SDM-nätverk och (2) hur man fördelar resurser och beräknar rutter i ett sådant nätverk för att minimera hårdvaruressurser. Först föreslår denna avhandling en WDM / SDM-nod som har förbikopplingsanslutningar mellan olika fibrer och arkitektur på begäran (AoD) för att effektivt minska antalet aktiva hårdvaraenheter inom noden. Sedan konstruerades två typer av nätverk: en med bypass-anslutningar i varje nod och en annan utan några bypass-anslutningar. Dessa nätverk kontrollerades av en mjukvarudefinierad nätverkskontroller (SDN). Styrenheten visste våglängdsresurserna i nätverket. Flera algoritmer applicerades på dessa nätverk för att utvärdera effekten av ett förbikopplingsnätverk och för att identifiera de önskade egenskaperna (för att hitta en kort längdväg och minska sannolikheten för spektrumfragmentering) av en algoritm som är lämplig för ett nätverk med bypass-anslutningar. Resultaten av att tillämpa de föreslagna algoritmerna i två nät visade att förbikopplingsförbindelserna ökade blockeringssannolikheten i liten topologi men inte påverkade resultaten i stor topologi. Resultaten i ett storskaligt nätverk med bypass-nätverk var nästan samma som resultaten i ett nätverk utan bypass-anslutningar. Bypassanslutningar är således lämpliga för storskaliga nätverk.

Full textAbstract:
Address data within geographic information systems (GIS) is used as reference data to link personal and administrative information, thus making it possible to locate and deliver goods and services to eligible persons. Preferably, every country must develop and maintain a single national address database (NAD) to eliminate data redundancy and provide a common point of reference across the board. In South Africa, the challenge is that there are separate address databases, which are developed and maintained by various public and private organizations – with little or no cooperation on data sharing. Currently, the establishment of a Committee for Spatial Information (CSI) which is tasked with the implementation of the South African Spatial Data Infrastructure (SASDI) and the publication of the South African Address Standard (SANS 1883) offer organizations an opportunity to collaborate towards the creation of a single address dataset. This research posits that the implementation of a successful data sharing initiative depends on the understanding of motivators and barriers of organizations participating in it. The research applied the case study method – with a semi-structured questionnaire – to assess the issues that motivate or obstruct GIS data sharing among three address organizations in South Africa. The results identified significant motivators that underlie the data sharing activities, e.g. reduced cost of data collection, improved data quality; and equally identified significant barriers that make organizations reluctant to enter into a data sharing initiative, e.g. data copyright and ownership, high staff-turnover, and lack of financial and technical resources. Although the case studies focused on address data in South Africa, the research findings can equally apply to other spatial datasets and are relevant for the successful implementation of the South African Spatial Data Infrastructure (SASDI).Dissertation (MIT)--University of Pretoria, 2012.

Full textAbstract:
This thesis seeks to review Urban Sustainability in cities of the Developing South within the broader spectrum of Sustainable Development. Notably, the Developing South has for many years struggled to embrace Sustainability in its general terms: in part, because of the fragile institutions that cannot be counted on to uphold sustainability in the truest sense of the word; and in part because of the numerous challenges that often distract any attempt to prioritize Sustainable Development. Sustainability then becomes an option in the midst of other options, rather than an option that should affect all other options. Narrowing it down further to matters urban makes it even stranger in a host of cities across the Developing South. It is against this backdrop that this study seeks to examine in depth the contextual challenges that have invariably stood in the way of Sustainable Development across the Developing South. While it may not be practically possible in a four-month study to offer outright solutions or recommendations that could address these challenges in entirety, this study nevertheless has endeavoured to stay true to the realities that are often ignored whenever challenges of Sustainable Development are mentioned on global platforms. Among these realities is the reality of slum presence in most cities of the Developing South that existentially complicates any equation for urban sustainability ever formulated to provide a way out or forward for these cities. State governments understand this too well, and so do Civil Society Organizations (CSOs) and international organizations alike involved in the crusade for improved living conditions for city resident, and in particular slum residents. Yet the State governments have never been as resolute in their quest for slum free cities. The question then remains: exactly what are the sustainable approaches for this noble cause? While the State governments have over the years insisted on enforcing conventional approaches (that include forced evictions, relocations and/ or redevelopment); one international network, however, thinks and responds differently to slum situations. The network is Shack/Slum Dwellers International (SDI). It is considerably this network of slum dwellers and their undeniably innovative approach to urban sustainability and inclusivity that largely frames the direction and general content of this study. Specifically, the methodology adopted in the study is one of a Case study - which in this case is SDI; and two separate Cases, namely Railway Relocation Action Plan (RAP) in Nairobi, Kenya and slum Re-blocking project in Joe Slovo, Cape Town, South Africa, respectively - as typical cases that captures in large part the enormous contribution that SDI is making towards inclusive and sustainable cities in the Developing South. In the discussion part, however, the study introduces Soft Systems Methodology (SSM) as a comparative methodology to SDI’s approach. SSM particularly benefits from LUMAS model and Social Learning – both key components that potentially reserve a dynamic capacity to enriching SDI’s approach as a future reference methodology for urban sustainability and inclusivity.

Full textAbstract:
Cette thèse vise à contribuer à l'amélioration des méthodes d'évaluation des systèmes de détection d'intrusions (en anglais, Intrusion Detection Systems ou IDS). Ce travail est motivé par deux problèmes actuels : tout d'abord, l'augmentation du nombre et de la complexité des attaques que l'on observe aujourd'hui nécessite de faire évoluer les IDS pour leur permettre de les détecter. Deuxièmement, les IDS actuels génèrent de trop fréquentes fausses alertes, ce qui les rend inefficaces, voir inutiles. Des moyens de test et d'évaluation sont donc nécessaires pour déterminer la qualité de détection des IDS et de leurs algorithmes de détection. Malheureusement, aucune méthode d'évaluation satisfaisante n'existe de nos jours. En effet, les méthodes employées jusqu'ici présentent trois défauts majeurs : 1) une absence de méthodologie rigoureuse d'évaluation, 2) l'utilisation de données de test non représentatives, et 3) l'utilisation de métriques incorrectes. Partant de ce constat, nous proposons une démarche rigoureuse couvrant l'ensemble des étapes de l'évaluation des IDS. Premièrement, nous proposons une méthodologie d'évaluation qui permet d'organiser l'ensemble du processus d'évaluation. Deuxièmement, afin d'obtenir des données de test représentatives, nous avons défini une classification des types d'attaques en fonction des moyens de détection utilisés par les IDS. Cela permet non seulement de choisir les attaques à inclure dans les données de test, mais aussi d'analyser les résultats de l'évaluation selon les types d'attaques plutôt que pour chaque attaque individuellement. Troisièmement, nous avons analysé un grand nombre d'attaques réelles et de programmes malveillants (communément appelés maliciels) connus, tels que les virus et les vers. Grâce à cette analyse, nous avons pu construire un modèle générique de processus d'attaques qui met en évidence la dynamique des activités d'attaque. Ce modèle permet de générer un nombre important de scénarios d'attaques, qui soient le plus possible représentatifs et variés. Pour montrer la faisabilité de notre approche, nous avons appliqué expérimentalement les étapes de notre démarche à deux systèmes différents de détection d'intrusions. .This thesis contributes to the improvement of intrusion detection system (IDS) evaluation. The work is motivated by two problems. First, the observed increase in the number and the complexity of attacks requires that IDSes evolve to stay capable of detecting new attack variations efficiently. Second, the large number of false alarms that are generated by current IDSes renders them ineffective or even useless. Test and evaluation mechanisms are necessary to determine the quality of detection of IDSes or of their detection algorithms. Unfortunately, there is currently no IDS evaluation method that would be unbiased and scientifically rigorous. During our study, we have noticed that current IDS evaluations suffer from three major weaknesses: 1) the lack of a rigorous methodology; 2) the use of non-representative test datasets; and 3) the use of incorrect metrics. From this perspective, we have introduced a rigorous approach covering most aspects of IDS evaluation. In the first place, we propose an evaluation methodology that allows carrying out the evaluation process in a systematic way. Secondly, in order to create representative test datasets, we have characterized attacks by classifying attack activities with respect to IDS-relevant manifestations or features. This allows not only to select attacks that will be included in the evaluation dataset but also to analyze the evaluation result with respect to attack classes rather than individual attack instances. Third, we have analyzed a large number of attack incidents and malware samples, such as viruses and worms. Thanks to this analysis, we built a model for the attack process that exhibits the dynamics of attack activities. This model allows us to generate a large number of realistic and diverse attack scenarios. The proposed methods have been experimented on two very different IDSes to show how general is our approach. The results show that the proposed approach allows overcoming the two main weaknesses of existing evaluations, i. E. , the lack of a rigorous methodology and the use of non-representative datasets. .

Los grupos 1, 2 y 3 se realizaron con la resina Aura® (SDI) y los grupos 4, 5 y 6 con la resina Tetric-N-Ceram®. Los grupos 1 y 4 fueron sumergidos en la bebida energizantes Red Bull® y los grupos 2 y 5 en la bebida Volt por 10 min/ 1 vez al día durante 7 días; por otro lado, los grupos 3 y 6 fueron grupos control, solo sumergidos en agua destilada/7 días. Se evaluó la resistencia a la tensión diametral a través de la máquina de ensayo universal Instron® (velocidad de 0.5mm/min - carga 100 KN), medida en MPa. Para evaluar los resultados de cada una de las variables y realizar el análisis univariado se procedió a obtener medidas de tendencia central y medidas de dispersión. Para evaluar el análisis bivariado se procedió a realizar la prueba de Kruskal Wallis. Resultados: El grupo control de la resina Aura® presentó una media y una D.E de 46.51 + 3.14, mientras que el grupo control de la resina Tetric-N-Ceram® presentó 46.04 + 3.22. Se encontró que la resina Aura® al ser sumergida en la bebida Red Bull®, presentó una media y una D.E de 35.58 + 7.63, mientras que al ser sumergida en la bebida Volt, presentó 35.24 + 5.13. Por otro lado, la resina Tetric-N-Ceram® luego de ser sumergida en la bebida Red Bull® presentó una media y una D.E de 37.46 + 6.18, mientras que al ser sumergida en Volt presentó 36.15 + 6.74. Conclusiones: No existen diferencias estadísticamente significativas al evaluar la resistencia a la tención diametral de las resinas tipo Bulk Fill, sometidas a la bebida energizante Red Bull® (p= 0.796), ni a Volt (p= 0.496).Objective: Compare in vitro diametral tensile strength of two Bulk Fill Aura® (SDI) and Tetric-N-Ceram® type resins subjected to two Red Bull® and Volt energy drinks. Materials and methods: The study was experimental in vitro. 132 Bulk Fill type resin bodies were evaluated, which were divided into six groups of 22 resin bodies each. Groups 1, 2 and 3 were made with Aura® resin (SDI) and groups 4, 5 and 6 with Tetric-N-Ceram® resin. Groups 1 and 4 were submerged in the Red Bull® energy drink and groups 2 and 5 in the Volt energy drink for 10 min / 1 time a day for 7 days. On the other hand, groups 3 and 6 were control groups, only immersed in distilled water for 7 days. The diametral tensile strength was evaluated through the Instron® universal test machine (speed 0.5mm / min - load 100 KN), measured in MPa. To evaluate the results of each of the variables and perform the univariate analysis, we proceeded to obtain measures of central tendency and measures of dispersion. To evaluate the bivariate analysis, the Kruskal Wallis test was carried out. Results: The control group of the Aura® resin presented a mean and a S.D of 46.51 + 3.14, while the control group of the Tetric-N-Ceram® resin presented 46.04 + 3.22. It was found that the Aura® resin when submerged in Red Bull® presented an average and a S.D of 35.58 + 7.63, while when submerged in Volt, it presented 35.24 + 5.13. On the other hand, the Tetric-N-Ceram® resin after being submerged in the Red Bull® presented a mean and a S.D of 37.46 + 6.18, while when submerged in Volt it presented 36.15 + 6.74. Conclusions: There are no statistically significant differences when evaluating the resistance to the diametral tension strength of the Bulk Fill type resins, submitted to the Red Bull® energy drink (p = 0.796), or to Volt (p = 0.496).

Fundamentale Voraussetzung für alle professionellen Kartendienste ist die Möglichkeit zur Kontrolle der grafischen Präsentation. Aus diesem Grund besteht ein starker Bedarf an der visuellen Darstellung von Geodaten. Diese transformiert rohe Informationen in wichtige und entscheidungstragende Werkzeuge. Der Feature Portrayal Service (FPS) hat die Aufgabe, diese Anforderungen umzusetzen und damit wesentlich zur kartographischen Interoperabilität in Geodateninfrastrukturen beizutragen.
Der Dienst entstammt dem internationalen Standard SLD 1.1.0 (Styled Layer Descriptor). Es handelt sich um einen Darstellungsdienst, der die interoperable Nutzung von Vektor-Daten, also von so genannten Features, ermöglicht. Dieser spezielle Web Map Service hat die Aufgabe, Geodaten von beliebigen Web Feature Services sowie rohe GML-Daten in einer gewünschten grafischen Ausprägung zu präsentieren. Dabei ist der jeweilige Nutzer in der Lage, eigene Darstellungen zu definieren und auf einen beliebigen Datenbestand anzuwenden.
Datenquellen, Darstellungsvorschriften und der Feature Portrayal Service selbst sind insofern unabhängig voneinander, dass diese drei Komponenten auf verschiedenen und voneinander unabhängigen Servern liegen können. Diese Art der Implementierung bezeichnet man als Component WMS.

Full textAbstract:
As zonas costeiras são áreas complexas que contemplam ambientes terrestres e marinhos que, além de possuírem enorme riqueza ambiental, também são áreas atrativas aos seres humanos por oferecer alimentos, lazer, negócios, transporte, entre outros. Algumas dificuldades de gerenciamento ocorrem pela complexidade, conflito de interesses e pelo fato de não haver padronização no levantamento de dados e disponibilização para a comunidade científica, órgãos públicos, etc. O uso de geotecnologias pode auxiliar na organização, padronização e compartilhamento destas informações em Atlas Web além de apoiar no planejamento e tomada de decisão pois agregam, em um único ambiente, diversos dados provenientes de fontes distintas. A construção de um modelo de dados espacial voltado à área ambiental, para ser utilizada em Infraestrutura de Dados Espaciais (IDE) é exemplificada a partir da modelagem de um bioindicador, Macrobentos, de qualidade de sedimentos. Este trabalho apresenta as etapas necessárias para a construção de modelo de dados espacial de Macrobentos e emprega a Região Metropolitana da Baixada Santista como referência, além de ilustrar e discutir as principais dificuldades para organizar os dados não padronizados. Conclui-se que a estruturação do conhecimento quando se trabalha com dados ambientais em um modelo é essencial para sua posterior integração em IDE. Constatou-se no processo de modelagem que questões metodológicas relativas ao processo de coleta podem dificultar ou até mesmo inviabilizar a integração de dados provenientes de diferentes estudos. A construção de um modelo de dados espacial e sua posterior publicação via Geoportal, como o apresentado neste estudo, poderá ser utilizado como referência para novas pesquisas com objetivos semelhantes.Coastal zones are complex areas that include marine and terrestrial environments. Besides its huge environmental importance, they also attract humans because they provide food, recreation, business, transportation, among others. Some difficulties to manage these areas are related with their complexity, diversity of interests and the absence of standardization to collect and share data to scientific community, public agencies, among others. The use of geo-technologies can be used in the organization, standardization and sharing of this information through Atlas Web and assists planning and decision making issues because it aggregates different files from distinct sources. The construction of a spatial database integrating the environmental business, to be used on Spatial Data Infrastructure (SDI) is illustrated by a bioindicator, Macrobenthos, that indicates the quality of the sediments. This research shows the required steps to build Macrobenthos spatial database based on Santos Metropolitan Region as a reference. Besides, it tries to illustrate the problems related to organize non standardized data. It can be concluded, when working with environmental data, that the structuring of knowledge in a conceptual model is essential for their subsequent integration into the SDI. During the modeling process it can be noticed that methodological issues related to the collection process may obstruct or make impracticable the data integration from different studies of the same area. The development of a database model and its subsequent publication in a Geoportal can be used as a reference for further research with similar goals.

Soussana, Myriam. "Adolescents avec Troubles Envahissants du Développement Sans Déficience Intellectuelle : quels liens entre les troubles anxieux et la reconnaissance des expressions faciales émotionnelles ?" Thesis, Montpellier 3, 2012. http://www.theses.fr/2012MON30074.
Full textAbstract:
Le taux de prévalence des troubles anxieux est très élevé chez les adolescents avec un Trouble Envahissant du Développement Sans Déficience Intellectuelle (TED-SDI). Hypothèse : Les troubles anxieux sont liés à la reconnaissance des expressions faciales émotionnelles dans les TED-SDI. Objectifs : 1) Etudier les liens entre la présence de troubles anxieux et la reconnaissance des expressions faciales émotionnelles auprès d’adolescents avec TED-SDI, en comparant leurs performances de reconnaissance des expressions faciales émotionnelles selon qu’ils aient ou non des troubles anxieux. 2) Vérifier si ces liens sont spécifiques aux TED-SDI, en comparant les performances à un groupe contrôle anxieux sans TED. 3) Caractériser les troubles anxieux dans les TED-SDI. Méthode : Il s'agit d'une étude transversale, descriptive et comparative d'une population de 46 adolescents avec TED-SDI âgés de 11 à 18 ans dont 20 ont des troubles anxieux. Ces derniers ont été comparés à 20 sujets contrôle du même âge ayant des troubles anxieux sans TED. Résultats : Dans la population avec TED, des liens sont mis en évidence entre la présence de troubles anxieux et l'altération de la reconnaissance des expressions de Colère et Tristesse. Il existe une corrélation spécifique aux TED-SDI entre l'augmentation du niveau d’anxiété sociale et l'amélioration de la reconnaissance de la Peur. Conclusion : Cette étude confirme l’existence de liens entre les troubles anxieux et la reconnaissance des expressions faciales émotionnelles dans les TED-SDI. Des pistes de réflexion sur l’évaluation et le développement de nouvelles prises en charge des troubles anxieux dans cette population sont proposéesPrevious studies reported a high prevalence of anxiety in adolescents with Autism Spectrum Disorders (ASD) without intellectual disability. Hypothesis: There is an association between anxiety disorders and facial emotional expressionrecognition in this population. Objectives: 1) to explore the relationship between anxiety disorders and facial emotional expression recognition in adolescents with ASD without intellectual disability and in a control group of adolescents without ASD. 2) to examine the specificity of this relation to ASD in comparing their performance in facial emotion recognition to that of a control group with anxiety disorder without ASD. 3) to characterize anxiety disorders in ASD without intellectual disability.Methods: Our study is cross-sectional, descriptive and comparative. Forty-six adolescents with ASD without intellectual disability aged between 11 and 18 years participated in the study. Among them, 20 had an anxiety disorder and were compared with 20 controls of the same age, with anxiety disorder without ASD. Results: In adolescents with ASD, anxiety disorders were related to impairments in recognition of the emotions like Anger and Sadness. Moreover, we found a significant correlation between the level ofsocial anxiety and improvement in Fear recognition that was specific to ASD.Conclusion and future directions: This study supports the hypothesis that anxiety disorders are relatedto facial emotion recognition in adolescents with ASD without intellectual disability. Clinicalimplications concerning the assessment of anxiety comorbidities in this population and the lack ofadapted treatments are discussed

Full textAbstract:
De nos jours, l'information géographique constitue une ressource incontournable dans un contexte de prise de décision et les données numériques spatiales sont de plus en plus fréquemment exploitées comme support et aide à la décision par de nombreuses organisations.L'institution militaire utilise elle aussi les données spatiales comme soutien et aide à la décision. A chaque étape d'une mission, des informations géographiques de tous types sont employées (données numériques, cartes papiers, photographies aériennes...) pour aider les unités dans leurs choix stratégiques. Par ailleurs, l'utilisation de réseaux de communication favorise le partage et l'échange des données spatiales entre producteurs et utilisateurs situés à des endroits différents. L'information n'est pas centralisée, les données sont répliquées sur chaque site et les utilisateurs peuvent ponctuellement être déconnectés du réseau, par exemple lorsqu'une unité mobile va faire des mesures sur le terrain.
La problématique principale concerne donc la gestion dans un contexte militaire, d'une application collaborative permettant la mise à jour asynchrone et symétrique de données géographiques répliquées selon un protocole à cohérence faible optimiste. Cela nécessite de définir un modèle de cohérence approprié au contexte militaire, un mécanisme de détection des mises à jour conflictuelles lié au type de données manipulées et des procédures de réconciliation des écritures divergentes adaptées aux besoins des unités participant à la mission.
L'analyse des travaux montre que plusieurs protocoles ont été définis dans les communautés systèmes (Cederqvist :2001 ; Kermarrec :2001) et bases de données (Oracle :2003 ; Seshadri :2000) pour gérer la réplication des données. Cependant, les solutions apportées sont souvent fonctions du besoin spécifique de l'application et ne sont donc pas réutilisables dans un contexte différent, ou supposent l'existence d'un serveur de référence centralisant les données. Les mécanismes employés en information géographique pour gérer les données et les mises à jour ne sont pas non plus appropriés à notre étude car ils supposent que les données soient verrouillées aux autres utilisateurs jusqu'à ce que les mises à jour aient été intégrée (approche check in-check out (ESRI :2004), ou utilisent un serveur centralisé contenant les données de référence (versionnement : Cellary :1990).
Notre objectif est donc de proposer des solutions permettant l'intégration cohérente et autant que possible automatique, des mises à jour de données spatiales dans un environnement de réplication optimiste, multimaître et asynchrone.
Nous proposons une stratégie globale d'intégration des mises à jour spatiales basée sur une vérification de la cohérence couplé à des sessions de mises à jour. L'originalité de cette stratégie réside dans le fait qu'elle s'appuie sur des métadonnées pour fournir des solutions de réconciliation adaptées au contexte particulier d'une mission militaire.
La contribution de cette thèse est double. Premièrement, elle s'inscrit dans le domaine de la gestion de la mise à jour des données spatiales, domaine toujours très actif du fait de la complexité et de l'hétérogénéité des données (Nous limitons néanmoins notre étude aux données géographiques vectorielles) et de la relative «jeunesse » des travaux sur le sujet. Deuxièmement, elle s'inscrit dans le domaine de la gestion de la cohérence des données répliquées selon un protocole optimiste, en spécifiant en particulier, de nouveaux algorithmes pour la détection et la réconciliation de données conflictuelles, dans le domaine applicatif de l'information géographique.
