Full textDer 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 textAn 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.

Full textOne 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 textHumanity 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.

Full textIn our first installment, analog and HD video terms were compared. 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.
Jabbour, Chadi. "Essays in the economics of Spatial Data Infrastructures (SDI) : business model, service valuation and impact assessment." Thesis, Montpellier, 2019. http://www.theses.fr/2019MONTD018.
Full textThe 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

Full textThis 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 textEn 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.

Full textResumo: 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 textThe 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.

Full textThe 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

Full textA 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.

Many growers in Arizona are switching from surface to drip irrigation. This change requires many changes in water management. One of the changes that growers are having the most difficulty with is the concept of applying gallons of water instead of inches. This paper helps growers make this conversion from inches to gallons and then back again. An accompanying EXCEL program, available on the web, will help growers determine run times and application amounts.

Full textOptiskt 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 textThis 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. .

Full textObjective: 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).

Full textCoastal 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.
