Miller, Stuart R. "Scandium bearing open framework materials." Thesis, University of St Andrews, 2007. http://hdl.handle.net/10023/570.
Full textAbstract:
Here I report the hydrothermal chemistry of scandium, examining the behavior of the Sc³⁺ cation in various systems, including phosphates, phosphites, phosphonates and carboxylates. In total, 27 different materials, 23 of which are novel, have been synthesised and their structures solved. Seven different scandium phosphate-based materials have been successfully synthesised using amines and alkali hydroxides as structure directing agents, producing chain, layer and framework materials. Thermal analysis of these materials indicated that they were not stable upon removal of the template, because there are hydrogen bonding networks between the template and free OH groups on the phosphate groups. Certain conditions lead to the crystallization of either kolbeckite, Sc(PO₄).2H₂O, or a langbeinite-type structure, (NH₄)₂Sc₂(HPO₄)(PO₄)₂, which are dense frameworks. Investigation of scandium phosphites leads to the formation of more thermally stable frameworks. Investigation of scandium phosphite-based materials using different structure directing agents yielded three framework phosphite materials and one layered phosphite / phosphate. The use of lithium hydroxide and ethylenediamine within scandium phosphite systems resulted in the crystallization of a gainesite type framework, (LiSc(HPO₃)₂)and (H₃N(CH₂)₂NH₃)₂Sc₄(HPO₃)₈, which distorts in order to accommodate the amine, but not the lithium cation. Decreasing the potential for the formation of hydrogen bonding networks in the phosphite systems led to the formation of framework structures, however these structures did not retain their crystalline integrity upon removal of the template. In order to impart structure directing properties upon scandium-based materials but avoid the formation of hydrogen bonding networks upon which the crystalline integrity is dependent, scandium phosphonates were investigated. Seven different scandium phosphonate materials have been synthesised, two of which have been solved from powder diffraction data, and one from a combination of powder diffraction data, molecular modeling and single crystal data. Synthesis of scandium phosphonate materials yielded two thermally stable, porous materials with reversible water adsorption properties, NaSc(CH₃PO₃)₂•H₂O and Sc₂(O₃PCH₂(NHC₅H₁₀NH)₋CH₂PO₃)₃4H₂O. The success of this approach led to the examination of scandium carboxylate metal organic framework materials. The incorporation of Sc³⁺ into microporous carboxylate frameworks yielded three aliphatic scandium carboxylates and six aromatic scandium carboxylates. The scandium analogue of MIL-53 shows potential for gas adsorption studies, as well as illustrating that scandium carboxylates can be isostructural to metal carboxylate materials already published. The scandium terephthalate, Sc₂(O₂CC₆H₄CO₂)₃, is a small pore framework material with an unprecedented structure type, the adsorption properties of which have been examined using a variety of different small gas molecules and hydrocarbons, including X-ray analysis of the structures whilst adsorbing different molecules. ⁴⁵Sc MAS NMR has been performed on the materials prepared pure and characterized in this thesis, in order to establish a library of chemical shifts for scandium in different framework environments.

The agent technology is used to develop systems that perform several complex tasks. This thesis presents the MAS-School method for modeling and implementing intelligent agent-based systems. The method presents a systematic approach to support a disciplined introduction of machine learning techniques in multi-agent systems from an early stage of design. The proposed approach encompasses guidelines to both the design and implementation phases of an agent-based system. It is based on an incremental development strategy that largely relies on simulation and testing techniques. This thesis also presents the ASYNC framework that is composed of software engineering tools for building agent based system for asynchronous, cooperative and intelligent agents. This thesis presents four complex applications that used the proposed method and framework in the design and implementation phase. The first case study presents an application that discovers the most appealing offerings for consumers in a retail market. The second case study presents a virtual marketplace for buying and selling goods with automatic negotiation. The third case study is a multi-agent system for a complex procurement scenario with interdependent and simultaneous auctions. This system achieved the third place in the 2004 TAC Classic competition. The fourth case study is a multi-agent system for a PC manufacturer scenario based on sourcing of components, manufacturing of PC's and sales to customers.

Full textAbstract:
This thesis presents an approach to modeling Multi Agent Systems (MAS). A framework and its implementation are presented as an extension to .NET. A number of definitions of agents are evaluated for the purpose of a broad understanding of the term software agent. Software agent has been defined in MAS context and its characteristics are identified and implemented. Motivation factors for building framework for MAS have been discussed. A number of existing technologies are discussed and evaluated. A number of agent systems previously developed are also being discussed in the middle part of the thesis. A model software agent has been defined and its characteristics are divided in two basic categories essential and optional. Its implementation has been distributed into different components throughout the MAS framework. Some of these characteristics are jointly implemented by a number of components and others responsibility rest on the individual components. Detail working of the MAS framework (i.e. what to do, when to do) is explained as guide to develop MAS using MAS framework. The protocols followed by the framework components to make communication possible between them are discussed at components level. The required information for developing MAS using MAS framework are also discussed. It answers the why, when and how questions in regards to using MAS framework A case study on Dynamic Truck Scheduling (DTS) system is discussed, designed and implemented using the MAS framework. DTS System has been used as a prototype application to test and evaluate the framework. DTS also represents a model problem that can be answered by using MAS; complete in-depth details about the problem statement are discussed. It also discusses the design and implementation of the solution along with the test results of the framework. Possible future expansion is presented in light of a number of limitations known of the MAS framework. The code working behind the different components of the MAS framework is given in appendices. Some important standards of XML that are used to pass information between agents and MAS framework components are also given in the format of tables.

Full textAbstract:
Multi-agent Systems (MAS) provide an increasingly relevant field of research due to their many applications to modelling real world situations where the behaviour of many individual, self-motivated, agents must be reasoned about and controlled. The problem of agent social reasoning is central to MAS, where an agent reasons about its actions and interactions with other agents. This is the most important component of MAS, as it is the interactions, cooperation and competition between agents that make MAS a powerful approach suited for tackling many complex problems. Existing work focuses either on specific types of social reasoning or general purpose agent practical reasoning - reasoning directed toward actions. This thesis argues that social reasoning should be considered separately from practical reasoning. There are many possible benefits to this separation compared to existing approaches. Principally, it can allow general algorithms for agent implementation, analysis and bounded reasoning. This viewpoint is motivated by the desire to implement social reasoning agents and allow for a more general theory of social reasoning in agents. This thesis presents the novel Expectation- Strategy-Behaviour (ESB) framework for social reasoning, which provides a generic way to specify and execute agent reasoning approaches. ESB is a powerful tool, allowing an agent designer to write expressive social reasoning specifications and have a computational model generated automatically. Through a formalism and description of an implemented reasoner based on this theory it is shown that it is possible and beneficial to implement a social reasoning engine as a complementary component to practical reasoning. By using ESB to specify, and then implement, existing social reasoning schemes for joint commitment and normative reasoning, the framework is shown to be a suitable general reasoner. Examples are provided of how reasoning can be bounded in an ESB agent and the mechanism to allow analysis of agent designs is discussed. Finally, there is discussion on the merits of the ESB solution and possible future work.

Full textAbstract:
Negli ultimi anni le tecnologie informatiche sono state al centro di uno sviluppo esponenziale.
Fra le incalcolabili innovazioni presentate, ha preso sempre più campo il paradigma per la programmazione ad agenti, che permette la realizzazione di sistemi software complessi, i quali, nell'informatica moderna, ricoprono un ruolo di fondamentale importanza.
Questi sistemi, denominati autonomi, mostrano caratteristiche interessanti per scenari dinamici; essi infatti devono essere robusti e resistenti, in grado di adattarsi al contesto ambientale e quindi reagire a determinate modifiche che si verificano nell'ambiente, comportandosi di conseguenza. Indicano perciò la pro-attività dell'entità presa in considerazione. In questa tesi saranno spiegate queste tipologie di sistemi, introdotte le loro caratteristiche e mostrate le loro potenzialità. Tali caratteristiche permettono di responsabilizzare i soggetti, rendendo il sistema auto-organizzato, con una migliore scalabilità e modularità, riducendo quindi le elevate esigenze di calcolo.
L'organizzazione di questo documento prevede i primi capitoli atti a introdurre il mondo dei sistemi autonomi, partendo dalle definizioni di autonomia e di agenti software, concludendo con i sistemi multi-agenti, allo scopo di permettere al lettore una comprensione adatta ed esaustiva.
I successivi capitoli riguardano le fasi di progettazione delle entità prese in esame, le loro forme di standardizzazione e i modelli che possono adottare, tra i quali il più conosciuto, il modello BDI.
Ne seguono due diverse metodologie per l'ingegneria del software orientata agli agenti.
Si conclude con la presentazione dello stato dell'arte degli ambienti di sviluppo conosciuti, contenente un'esauriente introduzione ad ognuno di essi ed una visione nel mondo del lavoro del loro apporto negli applicativi in commercio.
Infine la tesi terminerà con un capitolo di conclusioni e di riflessioni sui possibili aspetti futuri.

Full textAbstract:
Recent developments in embedded systems give robots access to the Internet and make them more flexible and capable of performing more complex applications. However, these robots are still limited in terms of size, CPU power, storage resources and memory. Consequently, these robots have only been manufactured for certain specific applications and cannot be re-used for other applications. This presents us with a challenge to design a software framework - Robot Colony. The Robot Colony enables robots to be suitable for a wide range of applications, not originally received from manufacturers, to achieve greater functionality, flexibility and utility. This research outlines the architecture and functionality of the Robot Colony to support the collaboration between devices in the P2P community and also analyse the JXTA platform, which was the framework originally proposed. Lastly we present a customized P2P architecture that specifically addresses the interaction betweensoftware components across the network. We further discuss the following technologies applied in theframework: * XML-based Directory Service Provider * HTTP-based publish/describe control commands * Remote Process Invoke To fully complete the project, a thorough evaluation of the framework based on either the JXTAplatform or the customized P2P channel has been conducted. This evaluation provides basic statistics data for the proposed framework design and implementation. Further more, we have presented a realtime Demo at the Smart Device lab of the Queensland University of Technology.

Full textAbstract:
This work focuses on the need for new knowledge to allow hierarchical multi-project management to be conducted in the construction industry, which is characterised by high uncertainty, fragmentation, complex decisions, dynamic changes and long-distance communication. A dynamic integrated project management approach is required at strategic, tactical and operational levels in order to achieve adaptability. The work sees the multi-project planning and control problem in the context of supply chain management at main contractor companies. A portfolio manager must select and prioritise the projects, bid and negotiate with a wide range of clients, while project managers are dealing with subcontractors, suppliers, etc whose relationships and collaborations are critical to the optimisation of schedules in which time, cost and safety (etc) criteria must be achieved. Literature review and case studies were used to investigate existing approaches to hierarchical multi-project management, to identify the relationships and interactions between the parties concerned, and to investigate the possibilities for integration. A system framework was developed using a multi-agent-system architecture and utilising procedures adapted from literature to deal with short, medium and long-term planning. The framework is based on in-depth case study and integrates time-cost trade-off for project optimisation with multi-attribute utility theory to facilitate project scheduling, subcontractor selection and bid negotiation at the single project level. In addition, at the enterprise level, key performance indicator rule models are devised to align enterprise supply chain configuration (strategic decision) with bid selection and bid preparation/negotiation (tactical decision) and project supply chain selection (operational decision). Across the hierarchical framework the required quantitative and qualitative methods are integrated for project scheduling, risk assessment and subcontractor evaluation. Thus, experience sharing and knowledge management facilitate project planning across the scattered construction sites. The mathematical aspects were verified using real data from in-depth case study and a test case. The correctness, usefulness and applicability of the framework for users was assessed by creating a prototype Multi Agent System-Decision Support System (MAS-DSS) which was evaluated empirically with four case studies in national, international, large and small companies. The positive feedback from these cases indicates strong acceptance of the framework by experienced practitioners. It provides an original contribution to the literature on planning and supply chain management by integrating a practical solution for the dynamic and uncertain complex multi-project environment of the construction industry.

Full textAbstract:
Dans la recherche de performance de chaînes logistiques, la modélisation et la simulation de ces chaînes prenant en compte des aspects organisationnels s‘avèrent nécessaire. Dans cette perspective, nous proposons tout d‘abord un nouveau cadre méthodologique de modélisation et simulation orienté agents de chaînes logistiques, prenant en compte explicitement les aspects organisationnels, tant structurels que dynamiques, ainsi que des observables et indicateurs dans la modélisation de ces chaînes. Ce cadre méthodologique est structuré selon deux niveaux d'abstraction principale qui sont : un niveau conceptuel et un niveau opérationnel. Pour chacun de ces niveaux nous avons différents modèles qui sont proposés et décrit en détail. Ensuite, afin de simuler les modèles de simulation de ces chaines logistiques obtenus par ce cadre méthodologique, nous proposons une architecture logicielle multi-paradigmes spécifique. Cette architecture qui supporte l‘intégration de différentes plates-formes de simulation, est basée sur un médiateur, constituant un système multi-agents, et assurant l‘interaction entre les simulateurs. Les agents de ce médiateur sont chargés de collecter les informations permettant de produire les observables, maintenir la structure organisationnelle lorsque des entités organisationnelles (groupes) sont distribués sur différents simulateurs, l‘interopérabilité entre ces simulateurs, et enfin garantir la validité de la simulation d‘un point de vue temporel. Enfin, la mise en œuvre du cadre méthodologique et de l‘architecture logicielle proposés sont illustrées sur un cas industriel réaliste de chaîne logistique. La présentation des phases de conception est détaillée ainsi que la spécification et l‘implémentation du cas industriel au sein de l‘environnement de modélisation et de simulation proposéIn the search for performance of supply chains, modeling and simulation of these chains, taking into account the organizational aspects are needed. In this perspective, firstly we propose a new methodology for modeling and simulation of supply chains oriented agents, taking into account explicitly the organizational aspects, both structural and dynamic as well as observable indicators in the modeling of these chains. This methodological framework is structured along two main levels of abstraction, conceptual and operational levels. For each level we have models that are proposed and described in details. Then, to simulate the simulation models of supply chains obtained by this methodological framework, we propose a multi-paradigm software architecture specific. This architecture supports the integration of different platforms simulation is based on a mediator, providing a multi-agent system, and ensuring the interaction between the simulators. The agents of this mediator is responsible for collecting required information to produce observables and maintaining the organizational structure while the organizational entities (groups) are distributed over different simulators and interoperability between these simulators, and finally ensuring the validity of the simulation for a temporal point of view. Finally, the implementation of the methodological framework and the proposed software architecture are shown in a realistic industrial case supply chain. The presentation of the design phase is detailed and the specification and implementation of industrial case in environmental modeling and simulation proposed

Full textAbstract:
Cognitive Maps (CMs) have shown promise as tools for modelling and simulation of knowledge in computers as representation of real objects, concepts, perceptions or events and their relations. This thesis examines the application of fuzzy theory to the expression of these relations, and investigates the development of a framework to better manage the operations of these relations.
The Fuzzy Cognitive Map (FCM) was introduced in 1986 but little progress has been made since. This is because of the difficulty of modifying or extending its reasoning mechanism from causality to relations other than causality, such as associative and deductive reasoning. The ability to express the complex relations between objects and concepts determines the usefulness of the maps. Structuring these concepts and relations in a model so that they can be consistently represented and quickly accessed and anipulated by a computer is the goal of knowledge representation. This forms the main motivation of this research.
In this thesis, a novel framework is proposed whereby single-antecedent fuzzy rules can be applied to a directed graph, and reasoning ability is extended to include noncausality. The framework provides a hierarchical structure where a graph in a higher layer represents knowledge at a high level of abstraction, and graphs in a lower layer represent the knowledge in more detail. The framework allows a modular design of knowledge representation and facilitates the creation of a more complex structure for modelling and reasoning.
The experiments conducted in this thesis show that the proposed framework is effective and useful for deriving inferences from input data, solving certain classification problems, and for prediction and decision-making.

Full textAbstract:
Throughout history floods have been part of the human experience. They are recurring phenomena that form a necessary and enduring feature of all river basin and lowland coastal systems. In an average year, they benefit millions of people who depend on them. In the more developed countries, major floods can be the largest cause of economic losses from natural disasters, and are also a major cause of disaster-related deaths in the less developed countries. Flood disaster mitigation research was conducted to determine how remotely sensed data can effectively be used to produce accurate flood plain maps (FPMs), and to identify/quantify the sources of error associated with such data. Differences were analyzed between flood maps produced by an automated remote sensing analysis tailored to the available satellite remote sensing datasets (rFPM), the 100-year flooded areas "predicted" by the Flood Insurance Rate Maps, and FPMs based on DEM and hydrological data (aFPM). Landuse/landcover was also examined to determine its influence on rFPM errors. These errors were identified and the results were integrated in a GIS to minimize landuse / landcover effects. Two substantial flood events were analyzed. These events were selected because of their similar characteristics (i.e., the existence of FIRM or Q3 data; flood data which included flood peaks, rating curves, and flood profiles; and DEM and remote sensing imagery.) Automatic feature extraction was determined to be an important component for successful flood analysis. A process network, in conjunction with domain specific information, was used to map raw remotely sensed data onto a representation that is more compatible with a GIS data model. From a practical point of view, rFPM provides a way to automatically match existing data models to the type of remote sensing data available for each event under investigation. Overall, results showed how remote sensing could contribute to the complex problem of flood management by providing an efficient way to revise the National Flood Insurance Program maps.

Parmar, Minaz. "MAC-REALM : a video content feature extraction and modelling framework." Thesis, Brunel University, 2013. http://bura.brunel.ac.uk/handle/2438/8161.
Full textAbstract:
A consequence of the ‘data deluge’ is the exponential increase in digital video footage, while the ability to find relevant video clips diminishes. Traditional text based search engines are no longer optimal for searching, as they cannot provide a granular search of the content inside video footage. To be able to search the video in a content based manner, the content features of the video need to be extracted and modelled into a content model, which can then act as a searchable proxy for the video content. This thesis focuses on the extraction of syntactic and semantic content features and content modelling, using machine driven processes, with either little or no user interaction. Our abstract framework design extracts syntactic and semantic content features and compiles them into an integrated content model. The framework integrates a four plane strategy that consists of a pre-processing plane that removes redundant data and filters the media to improve the feature extraction properties of the media; a syntactic feature extraction plane that extracts low level syntactic feature and mid-level syntactic features that have semantic attributes; a semantic relationship analysis and linkage plane, where the spatial and temporal relationships of all the content features are defined, and finally a content modelling stage where the syntactic and semantic content features are integrated into a content model. Each of the four planes can be split into three layers namely, the content layer, where the content to be processed is stored; the application layer, where the content is converted into content descriptions, and the MPEG-7 layer, where content descriptions are serialised. Using MPEG-7 standards to produce the content model will provide wide-ranging interoperability, while facilitating granular multi-content type searches. The framework is aiming to ‘bridge’ the semantic gap, by integrating the syntactic and semantic content features from extraction through to modelling. The design of the framework has been implemented into a prototype called MAC-REALM, which has been tested and evaluated for its effectiveness to extract and model content features. Conclusions are drawn about the research output as a whole and whether they have met the objectives. Finally, future work is presented on how concept detection and crowd sourcing can be used with MAC-REALM.

Full textAbstract:
Dans cette thèse, nous présentons MAKS-MAQAO (Multi-Architecture Knowledge-based System-Modular Assembly Quality Analyzer and Analysis). Cet outil nous permet d'avoir une combinaison d'analyses statique et dynamique des performances du code assembleur pour trouver les points chauds du code ou cette différence entre performances prédites et mesurées est la plus grande, cela traduisant certainement un code pouvant être mieux compilé. Sur ces portions de code, MAQAO identifie les optimisations réalisées(ou non-réalisées) par le compilateur. En effet, la compréhension du compilateur permet l'expression d'un code source propre à mieux satisfaire les conditions de déclenchement d'optimisations. Cet outil permet: - L'interprétation des optimisations proposés par le compilateur. A ce niveau, le système expert doit classifier les connaissances (toute information utile) et les nouvelles observations (nouveaux kernels). C'est une interprétation prédictive à partir d'observation pré-stockées. - La reconnaissance des kernels. A ce niveau, le but est que MAQAO devient intelligent. Pour une application donnée, il modélise ses kernels pour voir s'il y a des similitudes au modèle de kernels stockés dans la base de connaissance. - La proposition de nouvelles optimisation pour avoir des meilleures performancesIn this thesis, we advocate for a new approach in code optimization domain, a finer granularity in code analysis and optimization and a richer feed-back to the user. With the original iterative compilation approach, we have only the execution time or a few hardware counter for the whole code. We propose an intelligent system called MAKS-MAQAO (Multi-Architecture Knowledge based System-Modular Quality Analyzer and Optimizer), which is mainly based on post-compilation to provide more detailed information from an inner-view perspective. Furthermore, the feedback provided to the compiler is richer than simple raw cycle counts. This feed-back contains a set of recommendations and hypothesis to guide the user to apply pre-selected transformations that the intelligent system deems to be relevant. Therefore, not all the optimizations are chosen within the traditional iterative compilation process. Instead, a subset (which will grow with the system learning) is managed by the intelligent system

Ao longo dos anos, os computadores cresceram em importância no suporte à colaboração. Anteriormente, utilizados apenas como ferramentas em processos já consolidados de colaboração, hoje eles também têm um papel de propulsor. Como objetivo fundamental, sistemas colaborativos visam atender totalmente uma colaboração, sob o ponto de vista do modelo 3C (comunicação, coordenação e cooperação), disponibilizando ferramentas e funcionalidades que auxiliam estas etapas. Contudo, novas tecnologias estão possibilitando cada vez mais que os domínios destes tipos de sistemas se expandam, atuando não somente nas três divisões clássicas da colaboração, mas também em etapas preliminares deste processo, como busca de usuários e recursos. Isto é possível quando estamos imergidos em um cenário de computação ubíqua, por exemplo. Fazendo uso das características que este ambiente provê, como mobilidade e ciência do contexto, é possível incrementar os processos de colaboração. Etapa primordial de uma colaboração, a busca e definiçã
Over the years, computers have grown in importance in supporting collaboration. Previously used solely as tools in already established processes, today, beyond that purpose, they also have a hole of fostering new and unforeseen forms of collaboration. As a fundamental objective, collaborative systems intended to meet the whole set of demands of a collaboration, what means, under the terms of the 3C Model, to provide tools and features that address communication, coordination and cooperation between parts. Nevertheless, new technologies are allowing to further increase the workspace of these systems, bringing collaboration support beyond the three traditional divisions stated at the 3C Model and towards acting in preliminary stages, such as the search for users and resources. This is possible, for instance, as we are immersed in a scenario of ubiquitous computing. Using the characteristics that this environment provides, such as mobility and context-awareness, it is possible to improve the processes of collab

Ambitious goals for exploring Mars in the coming decades will push human spaceflight into new territory in duration, distance and isolation. In this regime, loss of system integrity due to some failure becomes especially dire. To that end, much meaningful work has centered on designing highly reliable space systems with low tolerance to failure. However, this thesis identifies a gap in space mission safety engineering within the realm of "survivability". Survivability is the ability of a system to address failure via contingency operations and to place the system in a state in which Loss of Mission, Vehicle or Crew are prevented. Manned space mission survivability is investigated in the context of decades-out missions - such as a Martian voyage in the late 2030's - which at the present time exhibit significant technological uncertainty. An abstracted functional breakdown beginning from assumed mission/campaign objectives and logically required architectural elements is proposed. Such a "generalized architecture" allows for a function-based failure and response analysis applicable across many possible futures. The Failure-Survivability Analysis Framework for Early Concepts (Fail-SAFE) is developed which 1) defines a generalized architecture, 2) injects a functional failure and assesses its impact, 3) enumerates and evaluates failure response options and 4) synthesizes these findings into design recommendations to promote system survivability. Particular emphasis is placed on those response options which leverage "functional multiplicity", or a redundancy in high-level functions across major architectural elements that can be substituted in case of failure. The framework is applied to two Case Studies. The first investigates a decompression failure during the outbound phases of a Mars transit mission. A Failure Effect Metric is defined which evaluates the impact and severity of the failure and Object Process Methodology is employed to determine its downstream effects. Contingency strategies (i.e. sets of response options) are generated and evaluated for their potential effectiveness. The analysis yielded a 108 contingency strategies, when limiting a strategy to a maximum of 4 individual responses. Recommendations to promote survivability to the failure are derived from these findings. The second Case Study validates the framework by applying it to a historical scenario - the Apollo 13 failure. The framework reproduces and highly appraises the successful course of action taken to save the crew. This validated framework may allow mission planners to design for survivability from the earliest stages of the architecting process, trading a narrowly optimal design for one robust to failure.

Full textAbstract:
This thesis presents a generalized Bayesian framework for a mobile robot to localize itself and a target, while building a map of the environment. The proposed technique builds upon the Bayesian Simultaneous Robot Localization and Mapping (SLAM) method, to allow the robot to localize itself and the environment using map features or landmarks in close proximity. The target feature is distinguished from the rest of features since the robot has to navigate to its location and thus needs to be observed from a long distance. The contribution of the proposed approach is on enabling the robot to track a target object or region, using a multi-stage technique. In the first stage, the target state is corrected sequentially to the robot correction in the Recursive Bayesian Estimation. In the second stage, with the target being closer, the target state is corrected simultaneously with the robot and the landmarks. The process allows the robot's state uncertainty to be propagated into the estimated target's state, bridging the gap between tracking only methods where the target is estimated assuming known observer state and SLAM methods where only landmarks are considered. When the robot is located far, the sequential stage is efficient in tracking the target position while maintaining an accurate robot state using close only features. Also, target belief is always maintained in comparison to temporary tracking methods such as image-tracking. When the robot is closer to the target and most of its field of view is covered by the target, it is shown that simultaneous correction needs to be used in order to minimize robot, target and map entropies in the absence of other landmarks.M.S.
This thesis presents a generalized framework with the goal of allowing a robot to localize itself and a static target, while building a map of the environment. This map is used as in the Simultaneous Localization and Mapping (SLAM) framework to enhance robot accuracy and with close features. Target, here, is distinguished from the rest of features since the robot has to navigate to its location and thus needs to be continuously observed from a long distance. The contribution of the proposed approach is on enabling the robot to track a target object or region, using a multi-stage technique. In the first stage, the robot and close landmarks are estimated simultaneously and they are both corrected. Using the robot's uncertainty in its estimate, the target state is then estimated sequentially, considering known robot state. That decouples the target estimation from the rest of the process. In the second stage, with the target being closer, target, robot and landmarks are estimated simultaneously. When the robot is located far, the sequential stage is efficient in tracking the target position while maintaining an accurate robot state using close only features. When the robot is closer to the target and most of its field of view is covered by the target, it is shown that simultaneous correction needs to be used in order to minimize robot, target and map uncertainties in the absence of other landmarks.

Redes de sensores sem fio são altamente dependentes de protocolos de controle de acesso ao meio para fazer uso efetivo dos poucos recursos disponíveis em seus nós sensores. Entretanto a maioria das otimizações propostas nos protocolos existentes focam em segmentos específicos do espaço de projeto. O que é considerado como uma otimização por uma classe de aplicações pode representar uma forte limitação para outras. Um protocolo com o objetivo de cobrir uma ampla fração do universo de aplicações de redes sensores deve apresentar algum mecanismo de configurabilidade ou adaptabilidade. Nesse sentido surgiu o Configurable Medium Access Control (C-MAC) (WANNER; OLIVEIRA; FROHLICH, 2007). O C-MAC funciona como um framework de estratégias de controle de acesso ao meio, as quais podem ser combinadas para produzir protocolos específicos de aplicação. Através desse paradigma, programadores de aplicações podem criar novos serviços de comunicação sob demanda e experimentar diferentes parâmetros de comunicação, coletando métricas para identificar e ajustar o protocolo às suas necessidades. Contudo, a arquitetura original do C-MAC fornece um baixo reuso de seus componentes em software, dificultando e reduzindo sua configurabilidade. Esta dissertação apresenta a proposta, implementação e avaliação de uma nova arquitetura para o framework C-MAC. Através de uma análise das diferentes categorias de protocolos MAC para redes de sensores, foram identificadas características comuns e especificidades desses protocolos que foram consideradas no desenvolvimento do novo C-MAC. Além disso, o que era um único grande componente na arquitetura original, foi separado em diferentes microcomponentes e novos microcomponentes foram incluídos de forma a suportar mais funcionalidades. Dessa forma, a arquitetura proposta possibilita um maior reuso de seus componentes em software, fornecendo maior configurabilidade e, consequentemente, suportando mais aplicações.
Abstract : Wireless sensor networks are highly dependent on medium access controlprotocols to make effective use of the few resources available on sensor nodes.Nevertheless, most of the optimizations proposed by existing protocols focuson specific segments of the design space. What is considered an optimizationby one class of applications can represent a strong limitation for others.A protocol aiming at covering a large fraction of the application universefor sensor networks must feature configuration or adaptation mechanisms.Therefore, the Configurable Medium Access Control (C-MAC) wascreated (WANNER; OLIVEIRA; FROHLICH, 2007). C-MAC is realized asa framework of medium access control strategies that can be combined toproduce application-specific protocols. Through this paradigm, applicationprogrammers can create new communication services on demand and experimentwith different communication parameters, collecting metrics to identifyand adjust the protocol to match their applications? requirements. Nonetheless,C-MAC original architecture provides low reuse of software components,hindering its configurability.This dissertation presents the proposal, implementation, and evaluation ofa new architecture for the framework C-MAC. Through the analysis of thedifferent categories of MAC protocols for sensor networks, common characteristicsand specificities of these protocols were identified and used in thedevelopment of the new C-MAC. Thus, the proposed architecture enables agreater reuse of its software components, providing greater configurabilityand, consequently, supporting a wider range of applications.

Full textAbstract:
In this dissertation, the central objective is to achieve fairness in bandwidth sharing amongst selfish users in a distributed system. Because of the inherent contention-based nature of the distributed medium access and the selfishness of the users, the distributed medium access is modeled as a non-cooperative game; designated as the Access Game. A p-CSMA type medium access scenario is proposed for all the users. Therefore, in the Access Game, each user has two actions to choose from: "transmit" and "wait". The outcome of the Access Game and payoffs to each user depends on the actions taken by all the users. Further, the utility function of each user is constructed as a function of both Quality of Service (QoS) and Battery Power (BP). Various scenarios involving the relative importance of QoS and BP are considered. It is observed that, in general the Nash Equilibrium of the Access Game does not result into fairness. Therefore, Constrained Nash Equilibrium is proposed as a solution. The advantage of Constrained Nash Equilibrium is that it can be predicated on the fairness conditions and the solution will be guaranteed to result in fair sharing of bandwidth. However, Constrained Nash Equilibrium is that it is not self-enforcing. Therefore, two mechanisms are proposed to design the Access Game in such a way that in each case the Nash Equilibrium of the Access Game satisfies fairness and maximizes throughput. Hence, with any of these mechanisms the solution of the Access Game becomes self-enforcing.Ph.D.

Full textAbstract:
A pesquisa sobre observância tributária floresceu no campo econômico, tendo como estudos seminais as obras de Allingham e Sandmo (1972) e Srinivasan (1973). Esses artigos basearam-se na teoria de Becker (1968) sobre crime e punição, aceitando o paradigma econômico clássico, que parte do pressuposto de que os indivíduos adotam comportamentos racionais. Nas últimas décadas, contudo, muitos pesquisadores notaram que esse paradigma, do qual derivou aquilo que veio a ser chamado pela academia de \"paradigma do crime\", explicava apenas parcialmente o comportamento do contribuinte. Surge, então, toda uma linha de pesquisa contrapondo esse paradigma racional, partindo da constatação de que o comportamento do contribuinte é muito mais complexo do que inicialmente se supunha, merecendo uma análise multidisciplinar, ou seja, que não se restrinja ao campo econômico, mas que também abarque outras disciplinas. Esse novo paradigma foi denominado pela academia de \"paradigma do serviço\" que, em linhas gerais, contempla outros fatores envolvidos no ato de pagar tributos, inclusive psicológicos, pressupondo, de tal modo, que o contribuinte não é um indivíduo racional unicamente preocupado em maximizar sua utilidade, devendo ser visto pela administração pública como uma espécie de cliente, e recebendo tratamento adequado e serviços públicos de qualidade em contrapartida ao cumprimento de suas obrigações tributárias. O presente estudo faz uma apreciação dos dois paradigmas, introduzindo nessa avaliação conceitos da ciência denominada Análise do Comportamento, cujos ensinamentos sobre a aprendizagem e o comportamento humano têm o potencial de contribuir de forma significativa para o entendimento do assunto. Testando os pressupostos teóricos apresentados no decorrer do trabalho, foram realizados dois estudos empíricos, tomando-se como base o modelo criado pelo pesquisador e psicólogo Erich Kirchler, denominado Slippery Slope Framework, que confirma estudos anteriores e demonstra que tanto punições quanto recompensas são instrumentos eficazes no combate à evasão fiscal, sugerindo que a integração dos paradigmas \"do crime\" e \"do serviço\", bem como a inserção dos princípios da Análise do Comportamento nesta análise é um caminho promissor no combate à evasão fiscal.Research on tax compliance has arisen in the economic field with seminal studies based upon the works of Allingham and Sandmo (1972) and Srinivasan (1973). Such articles were based on Becker\'s theory (1968) on crime and punishment, accepting the classic economic paradigm, which presupposes that individuals show rational behaviors. Nevertheless, in the past decades, many researchers have noticed that such paradigm, which gave rise to what is referred to, by the academy, as \"crime paradigm\", explained the behavior of taxpayers solely in part, and an entire line of research opposing such rational paradigm arose, based upon the verification that the behavior of taxpayers is much more complex than what was originally presumed, deserving a multidisciplinary analysis, i.e., not restricted to the economic field, but that, further, encompasses other subjects. Such new paradigm was designated by the academy as \"service paradigm\" that, in general, contemplates other factors involved in the act of paying taxes, including psychological factors, thus presupposing that taxpayers are not rational individuals solely concerned about maximizing the function thereof, they should be deemed, by the public administration, to be clients, and should receive appropriate treatment and quality public services in return for complying with their tax obligations. This study analyzes two paradigms, introducing in such analysis concepts of the science called Behavior Analysis, the teachings on learning and human behavior of which have potential to significantly contribute to better understanding the subject. Testing the theoretical assumptions presented throughout the study, two empirical analyses were conducted, based upon the model created by researcher and psychologist Erich Kirchler, referred to as Slippery Slope Model, which confirms previous studies and indicates that both punishment and reward are effective tools to fight against tax evasion, suggesting that integrating \"crime\" and \"service\" paradigms and inserting concepts of the Behavior Analysis Science in this analysis is highly promising to fight against tax evasion.

Full textAbstract:
Dynamic selection and composition of autonomous and loosely-coupled Web services is increasingly used to automate business processes. The typical long-running characteristic of business processes imposes new management challenges such as dynamic adaptation of running process instances. However, current process orchestration engines provide limited flexibility to dynamically adapt to changing runtime conditions (e.g., presence of faults). Additionally, current process specification languages exhibit some limitations regarding modularity of crosscutting management concerns. In particular, monitoring and adaptation logic is often scattered across several process definitions and intertwined with the business logic. This leads to monolithic and complex processes that are hard to understand, reuse, maintain, and evolve. To address these limitations, we developed a policy-based change management framework, named Manageable and Adaptable Service Compositions (MASC), to declaratively express crosscutting monitoring and process adaptation concerns in a separate and modular way. MASC policies use a set of simple, but flexible and relatively powerful, constructs to declaratively specify policies that govern: (1) discovery and selection of services to be used, (2) monitoring to detect the need for adaptation, (3) reconfiguration and adaptation of the process to handle special cases (e.g., context-dependant behaviour) and recover from typical faults in service-based processes. The identified constructs are executed by a lightweight service-oriented management middleware named MASC middleware. The adaptation is transparent because it preserves the original functional behaviour of the business process and does not tangle the adaptation logic with that of the business process. Additionally, policies do not have to be necessarily defined when designing the process; they can also be introduced later during deployment or at runtime. We implemented a MASC proof-of-concept prototype and evaluated it on Stock Trading case study scenarios. We conducted extensive studies to demonstrate the feasibility of the proposed techniques and illustrate the benefits of our approach in providing adaptive composite services using the policy-based approach. Our performance and scalability studies indicate that MASC middleware is scalable and the introduced overhead are acceptable.

Full textAbstract:
Background: The prevalence of mental disorder in children and young people in the UK is estimated at 10-20% (Meltzer et al. 2003). The World Health Organisation advocates urgent preventive measures to reduce the impact of a predicted steep rise in global rates of depression (World Health Organization 2008 ). The mental health of young people is therefore a public health issue, nationally and globally. The UK children's policy agenda proposes that promoting emotional wellbeing is a shared responsibility between children's agencies at the Tier 1 level of Child and Adolescent Mental Health Services (DCSF 2008), but further research is required to develop low intensity, evidence based interventions to promote emotional and mental health. Schools have a remit to address emotional problems in students and evidence exists to support school based interventions to promote emotional wellbeing. However young people encounter barriers to help-seeking in primary care, which need to be understood in order to deliver appropriate support. There is an emerging evidence base for using guided self-help (GSH) to deliver cognitive behaviour therapy-based interventions to adults in primary mental health care (Gellatly et al. 2007). It is not known whether using GSH in high schools to deliver emotional wellbeing interventions to young people would be feasible or acceptable. Aims: To develop an emotional wellbeing intervention for high schools using GSH, and evaluate it for feasibility and acceptability. Methods: The Medical Research Council (MRC) Framework for complex interventions (MRC 2000) provided the conceptual structure of the research. The methodological approach was also strongly influenced by standards for qualitative research proposed by Popay et al (1998), particularly the need to be responsive to the research context. There were three stages: Consultation, Development and Implementation. In the Consultation stage 54 young people aged 11-15 were consulted in 6 focus groups in 3 inner city high schools in the UK. The outcomes supported the development of a GSH intervention, named the 'Change Project', which was the focus of the Development Stage. Pastoral and Special Educational Needs staff in schools received brief training to deliver the intervention, followed by weekly supervision for the duration of the Project. In the Implementation Stage the Change Project was piloted in the same 3 high schools. The Project was evaluated for acceptability and feasibility using qualitative interview methods and a survey of students. Two instruments were incorporated: the PHQ-2 (Kroenke et al. 2003) was included to identify students who would benefit from a referral to the school nurse and the Rosenberg Self Esteem Scale (Rosenberg 1965) was used to explore its suitability as an outcome measure with the target population. Results: Eight Project workers delivered the Change Project. Twenty one students used it. They were aged 11-17 years and included male, female, white and non-white students. Self reported personal outcomes for students were generally positive. Nine sets of baseline and post-intervention RSES scores were collected. There was a general trend for improvement in scores. Presenting difficulties included potentially clinical disorders which were successfully addressed with support from school nurses. Interviews were conducted with 23 students, and 27 school staff and questionnaire data were collected from 140 students. Project worker reports of the Change Project's acceptability and feasibility were mixed, though also generally positive. The acceptability and feasibility of the RSES is discussed. The ethos of pastoral care, support of senior figures and other contextual factors affected implementation quality in each school. Help-seeking in the young people was driven by peer norms of hiding signs of vulnerability. Conclusions: The Change Project intervention was generally felt to be useful and relevant and overall it was welcomed by staff and students. The intervention has potential for further development. Its acceptability and feasibility were co-dependent and strongly influenced the implementation processes, indicating the value of investing time in understanding social and cultural factors in the research context. Understanding organisational and individual barriers and facilitators of help-seeking in young people may encourage use of emotional support in school.

[Truncated abstract] Developing wireless sensor network communication protocols for industrial environments is a challenging task. The wireless channel conditions in industrial environments are harsher as a result of multipath propagation of radio signals within an environment where the mechanics of the surrounding industrial activities often lead to severe small-scale fading effects. The design of network protocols to function in such an environment needs to provide a robust communication platform for the wireless sensor nodes, while optimizing the utilization of the limited node resources available. As existing general MAC protocols for wireless sensor networks do not work well under harsh channel conditions, we address this problem in this thesis by proposing a medium access control (MAC) protocol framework for wireless sensor networks in industrial environments. To describe the impact of an automated industrial site on small-scale fading effects in an industrial indoor wireless network, we use a site-specific ray-tracer for predicting signal propagation based on building blue prints to simulate the signal propagation paths through an industrial site with periodically moving objects. We found that in a fully automated industrial site, the periodic movements of objects with constant velocities result in an approximately periodic distribution of fading periods in the channel. Based on this finding, we propose a link state dependent TDMA-based MAC protocol for wireless sensor networks designed for automated industrial applications. ... This technique also conserves energy and maximizes packet integrity as the sensor nodes avoid performing network activities when the channel is sampled to be affected by fading. As a measure for fault-tolerance, we also propose a dynamic link reconstruction technique that allows sensor nodes to reconstruct new parent links when their present links are severely affected by fading. MAC protocols that adopt active buffering in fading-affected channels suffer bufferoverflow and latency issues as a result of the postponement of scheduled transmissions during periods when the channel is in a fade. Consequently, time-sensitive data packets that may contain critical information may miss their deadlines in a severely affected fading channel. Hence, we propose a general fading-aware data management (FADE) MAC protocol extension that uses buffer nodes to offload the memory buffer off sensor nodes in the network and prioritizes traffic based on a simple proposed priority scheme. The FADE extension provides a balance balance between minimum end-to-end latency for critical event reporting, high packet delivery guarantee, low energy consumption, and minimum buffer requirements on the sensor nodes. In summary, this thesis presents the design, implementation, and evaluation of all our proposed network protocols that are combined as a framework for wireless sensor networks in industrial environments.

En particulier, nous nous focalisons sur la conception de nouveaux protocoles distribués pour une utilisation optimale/améliorée des ressources radio disponibles. Par ailleurs, nous caractérisons les performances des réseaux ad hoc à accès aléatoire au canal en utilisant des paramètres de plusieurs couches avec aptitude de transfert d'information (data forwarding). La majeure partie de nos analyses se base sur le concept d'interaction entre les couches OSI (cross-layer). En effet, cette nouvelle et attractive approche est devenue en peu de temps omniprésente dans le domaine de recherche et développement et dans le domaine industriel. Les métriques de performances qui nous intéressent sont la stabilité des files d'attentes de transfert, le débit, le délai et la consommation d'énergie. Principalement, la compréhension de l'interaction entre les couches MAC/PHY et routage du standard IEEE 802.11e DCF/EDCF, d'une part, et l'interaction entre noeuds en terme d'interférences, d'autre part, constituent le coeur central de notre travail

Es wurden verschiedene NMR-spektrokopische Messungen an flexiblen und chiralen MOFs durchgeführt. Zur Untersuchung der Porensysteme kamen 129Xe-NMR und 13C-NMR an adsorbiertem CO2 zum Einsatz, während die MOF-Gitter und ihre Wechselwirkungen mit adsorbierten Gastmolekülen mittels 13C- und 1H-MAS-NMR-Spektroskopie studiert wurden. Während DUT-8(Ni) Flexibilität zeigt, weist DUT-8(Cu) ein starres Gitter auf. Die Flexibilität der sogenannten Solid-Solutions hängt in ausgeprägter Weise vom Verhältnis der funktionalisierten bdc-Linker 2,5-bme-bdc und db-bdc ab. Dieses Verhältnis hat zudem einen großen Einfluss auf die Orientierung der adsorbierten CO2-Moleküle. Es wurde erstmals eine Methode vorgestellt, die den Festkörper-NMR-spektroskopischen Nachweis chiraler Seitengruppen in chiralen MOFs erlaubt, wie anhand des chiral modifizierten UMCM-1 (ChirUMCM-1) demonstriert wurde. Die Chiralität kann einen NMR-spektroskopisch messbaren Einfluss auf die intrinsische Dynamik des MOF-Gitters ausüben, wie am chiral modifizierten DUT-32 deutlich wurde, dessen chirale Seitengruppe selektiv 15N- und 13C-isotopenmarkiert wurde.

The support of multimedia traffic over IEEE 802.11 wireless local area networks (WLANs) has recently received considerable attention. This dissertation has proposed a new framework that provides efficient channel access, service differentiation and statistical QoS guarantees in the enhanced distributed channel access (EDCA) protocol of IEEE 802.11e. In the first part of the dissertation, the new framework to provide QoS support in IEEE 802.11e is presented. The framework uses three independent components, namely, a core MAC layer, a scheduler, and an admission control. The core MAC layer concentrates on the channel access mechanism to improve the overall system efficiency. The scheduler provides service differentiation according to the weights assigned to each Access Category (AC). The admission control provides statistical QoS guarantees. The core MAC layer developed in this dissertation employs a P-Persistent based MAC protocol. A weight-based fair scheduler to obtain throughput service differentiation at each node has been used. In wireless LANs (WLANs), the MAC protocol is the main element that determines the efficiency of sharing the limited communication bandwidth of the wireless channel. In the second part of the dissertation, analytical Markov chain models for the P-Persistent 802.11 MAC protocol under unsaturated load conditions with heterogeneous loads are developed. The Markov models provide closed-form formulas for calculating the packet service time, the packet end-to-end delay, and the channel capacity in the unsaturated load conditions. The accuracy of the models has been validated by extensive NS2 simulation tests and the models are shown to give accurate results. In the final part of the dissertation, the admission control mechanism is developed and evaluated. The analytical model for P-Persistent 802.11 is used to develop a measurement-assisted model-based admission control. The proposed admission control mechanism uses delay as an admission criterion. Both distributed and centralized admission control schemes are developed and the performance results show that both schemes perform very efficiently in providing the QoS guarantees. Since the distributed admission scheme control does not have a complete state information of the WLAN, its performance is generally inferior to the centralized admission control scheme. The detailed performance results using the NS2 simulator have demonstrated the effectiveness of the proposed framework. Compared to 802.11e EDCA, the scheduler consistently achieved the desired throughput differentiation and easy tuning. The core MAC layer achieved better delays in terms of channel access, average packet service time and end-to-end delay. It also achieved higher system throughput than EDCA for any given service differentiation ratio. The admission control provided the desired statistical QoS guarantees.Ph.D.

Full textAbstract:
Approved for public release; distribution is unlimitedOpaque communities confound homeland security situational awareness and integration efforts, which generates pervasive threat perceptions that have often escalated into governmental interventions and violent confrontations. Governmental failures to effectively communicate with, and judiciously address past incidents involving opaque communities, have led to tactical response disasters; future inabilities to foster contact with such groups could present grave, unforeseen challenges to homeland security and surrounding community resiliency efforts. Utilizing a structured focused method, this thesis explores whether governmental entities adopt a common set of operational assumptions regarding threats emanating from opaque communities and, if so, whether alternative interactional frameworks for integrating such communities into homeland security efforts are available. This thesis presents case study analysis of interventions involving the opaque communities of the Branch Davidians at Waco, MOVE in Philadelphia, and FLDS YFZ Ranch in Eldorado and finds that ingrained default oppositional frameworks influenced governmental deliberations throughout each event. This inquiry concludes that targeted constructive communication strategies utilizing dedicated interlocutors knowledgeable about a given community will assist in preventing future unnecessary and costly official interventions.

Em um contexto atual de busca pelo desenvolvimento sustentável, surge a necessidade de alteração de mentalidades e práticas. A Produção mais Limpa figura como um dos exemplos de iniciativa compatível com essa demanda. Seu objetivo é que sejam considerados previamente os efeitos negativos dos processos produtivos, fazendo com que seja reduzido o desperdício e a geração de poluentes. Mesmo estando de acordo com as aspirações atuais de busca por uma produção industrial mais sustentável, sua disseminação não ocorreu de forma satisfatória. Esta dissertação visa contribuir para a compreensão das barreiras para a aplicação da Produção mais Limpa, bem como identificar quais fatores devem estar presentes para que se atinja o sucesso na sua adoção, possibilitando a geração de uma proposta de framework. Para atingir os objetivos propostos um instrumento de pesquisa foi criado com base na literatura e entrevistas com profissionais. Com esse instrumento foi executada uma survey com profissionais que possuem envolvimento com a temática de Produção mais Limpa, atingindo-se um total de 185 respondentes. A partir dos resultados da análise de componentes principais, ficou evidenciado que os fatores mais cruciais dizem respeito à organização, estando relacionados com a visão, a cultura, o planejamento estratégico e os subsídios para a implantação da Produção mais Limpa, que constituíram na primeira e segunda componentes da análise. No caso das barreiras, destaca-se a existência de uma visão e cultura organizacional inadequadas (primeira componente), seguido da falta de apoio externo (segunda componente). Também foram encontrados indícios de que pode haver uma má compreensão do conceito de Produção mais Limpa, além de uma educação ambiental inadequada. Ao analisarem-se as medidas que podem ser tomadas para que a Produção mais Limpa tenha sua aplicação de forma mais efetiva, percebe-se que o principal é o reposicionamento do ambiente externo como um forte incentivador da aplicação da Produção mais Limpa, abandonando a posição de destaque ao serem observadas as barreiras.In t In the present context of pursuit for sustainable development, the need to alter mentalities and practices arises. Cleaner Production is an example of initiative compatible with this demand. Cleaner Production aims at considering beforehand negative effects of the productive process, reducing wastes and pollutant generation. This concept is aligned with current aspirations of pursuing for a more sustainable industrial production, but its dissemination did not occur in a satisfactory way. This dissertation seeks to contribute for comprehension of barriers to Cleaner Production application, as well as identify critical success factors that exist to achieve success in its adoption, making possible the conception of a framework proposal. To reach the proposed objectives a research instrument was created based on literature and interviews with professionals. With this instrument a survey was performed with professionals that work with Cleaner Production; a total of 185 responses were obtained. Results of the Principal Component Analysis made evident that critical factors are related with organization aspects, such as vision, culture, strategic planning and subsides for Cleaner Production implementation, that composed the first and second components. Regarding the barriers, it was emphasized the existence of an inadequate organizational vision and culture (first component), followed by lack of external support (second component). It was also found evidences that a mistaken comprehension of the Cleaner Production concept might exist, as well as an inappropriate environmental education. Considering measures that might be taken in order to disseminate Cleaner Production more effectively, it was noticed that is important to repositioning the external environment, making it a strong support in Cleaner Production applications, leaving behind a position of highlight when barriers are observed.

Full textAbstract:
This research is based on real issues that have been recognised within the global organisation, Rolls-Royce. The first aim concerned an issue that many companies face, the difficulty that employees face in locating the knowledge and information they require, especially in larger organisations. The developed solution of an Information Map proved to be a success in providing people within the Submarines business with the location of' Configuration Management information. The concept of the Information Map is one that can be adopted by any business as the stages in the tools development have been well documented within Chapters Four, Five and Six. Analysis of the success of the Information Map led to the derivation of 10 lessons learned. These were then verified in a second case study of an intranet development. The second aim of the research was to create a Knowledge Management framework that could be adapted by companies looking to invest in Knowledge Management and provide them with a guide to use. This framework was built from the lessons learned from the Information Map and from other best practice derived from available literature and within Rolls-Royce. The work conducted within the Support business tries to fill in gaps in current research by offering companies a new approach to Knowledge Management, which was based upon the way that industries work today. The creation of the Knowledge Management framework simplifies the work conducted and offers practitioners an easy, high-level approach to the adoption of Knowledge Management by grouping the process into ten steps. This is presented in a fashion that is easy to follow and ultimately offers a guide to make the best use of the resources and budget available to Knowledge Management practitioners. Overall the research addresses the 'real' issues faced by Knowledge Management practitioners. The main contributions to the Knowledge Management domain are the Information Map, action research approach, implementation of Knowledge Management tools for the users needs and a Framework as a guide for industry.

In der vorliegenden Publikation wird ein Verfahren beschrieben, dass eine infrastrukturlose Positionierung im Inneren von Gebäuden ermöglicht. Unter infrastrukturlos wird in diesem Zusammenhang die autarke Positionierung eines Systems auf Basis seiner Inertialsensorik ohne den Einsatz von im Gebäude installierter Zusatzlösungen, wie Funksysteme, verstanden. Aufgrund der insbesondere über die Zeit erhöhten Fehlerbehaftung solcher Sensoren werden bei diesem Verfahren Innenraumkarten in den Lokalisierungsprozess einbezogen. Diese Kartendaten erlauben den Ausschluss invalider Positionen und Bewegungen, wie das Durchqueren von Wänden, und ermöglichen somit eine wesentliche Verbesserung der Ortungsgenauigkeit.

Map projections lie at the core of geographic information systems and numerous projections are used today. The reprojection between different map projections is recurring in a geographic information system and it can be parallelized with multi-core CPUs and GPUs. This thesis implements a parallel analytic reprojection algorithm of raster data in C/C++ with the parallel programming frameworks Pthreads, C++11 STL threads, OpenMP, Intel TBB, CUDA and OpenCL. The thesis compares the execution times from the different implementations on small, medium and large raster data sets, where OpenMP had the best speedup of 6, 6.2 and 5.5, respectively. Meanwhile, the GPU implementations were 293 % faster than the fastest CPU implementations, where profiling shows that the CPU implementations spend most time on trigonometry functions. The results show that reprojection algorithm is well suited for the GPU, while OpenMP and Intel TBB are the fastest of the CPU frameworks.Kartprojektioner är en central del av geografiska informationssystem och en otalig mängd av kartprojektioner används idag. Omprojiceringen mellan olika kartprojektioner sker regelbundet i ett geografiskt informationssystem och den kan parallelliseras med flerkärniga CPU:er och GPU:er. Denna masteruppsats implementerar en parallel och analytisk omprojicering av rasterdata i C/C++ med ramverken Pthreads, C++11 STL threads, OpenMP, Intel TBB, CUDA och OpenCL. Uppsatsen jämför de olika implementationernas exekveringstider på tre rasterdata av varierande storlek, där OpenMP hade bäst speedup på 6, 6.2 och 5.5. GPU-implementationerna var 293 % snabbare än de snabbaste CPU-implementationerna, där profileringen visar att de senare spenderade mest tid på trigonometriska funktioner. Resultaten visar att GPU:n är bäst lämpad för omprojicering av rasterdata, medan OpenMP är den snabbaste inom CPU ramverken.

Full textAbstract:
Bakgrund: Relationsvåld riktat mot kvinnor är ett globalt folkhälsoproblem med många negativa hälsokonsekvenser. Våld i nära relationer sägs vara vanligt och kulturellt accepterat i Ghana trots införandet av Domestic Violence Act år 2007 som gör relationsvåld illegalt. Forskning har visat att sjuksköterskor besitter en nyckelposition för att arbeta mot relationsvåld men att många sjuksköterskor saknar beredskap. Sjuksköterskeutbildningen har visat sig vara otillräcklig vad gäller relationsvåld. Syfte: Att beskriva Ghananska sjuksköterskestudenters attityder till relationsvåld och hur ämnet berörs i utbildningen. Metod: En deskriptiv kvalitativ studie som baseras på data från sex semistrukturerade intervjuer med Ghananska sjuksköterskestudenter. Intervjuerna spelades in, transkriberades och analyserades därefter med hjälp av innehållsanalys. Resultat: Sjuksköterskestudenterna kände sig förberedda för att möta kvinnor utsatta för relationsvåld och ansåg att sjuksköterskan hade en viktig roll. Studenterna tyckte att relationsvåld var ett problem som skulle lösas inom familjen och sjuksköterskan beskrevs ha en roll som rådgivare. Ingen av studenterna tyckte att relationsvåld var acceptabelt. De pratade om könsroller, mannens överordnade position i familjen och att våld uppstod när rollerna inte upprätthölls. Låg utbildningsnivå sågs som en orsak till att relationsvåld uppstår och utbildning föreslogs vara en nyckel till att eliminera relationsvåld. Slutsats: En förbättrad sjuksköterskeutbildning som problematiserar relationsvåld ur ett genusperspektiv behövs för att påverka blivande sjuksköterskors attityder och möjliggöra en professionell vård av utsatta patienter världen över. Klinisk betydelse: För att förbättra sjuksköterskeutbildningar borde relationsvåld och dess samband med den könsbestämda maktstrukturen uppmärksammas i större utsträckning.Background: Intimate partner violence (IPV) is a global public health problem with many negative health consequences. IPV is said to be common and culturally accepted in Ghana despite the introduction of The Domestic Violence Act 2007 that prohibits IPV. Research has shown that nurses are in a key position to handle IPV though many nurses are unprepared. A lack of IPV education for nursing students has been identified. Aim: To describe Ghanaian nursing students’ attitudes toward IPV and how it is addressed in their education. Method: A descriptive qualitative study based on data from six semi-structured interviews with Ghanaian nursing students. Interviews were recorded, transcribed and analysed with content analysis. Results: Ghanaian nursing students felt prepared to meet IPV and they thought that nurse’s role was of importance. Students advocated for a domestic handling of IPV and described the nurse’s role as a counsellor. None of the students found IPV acceptable. Students spoke about the gender roles and illuminated the view of the man as superior and that lack of role performance might lead to IPV. Low educational level was spoken of as a reason for the prevalence of IPV and suggested as a key to the elimination of IPV. Conclusion: To affect nurses’ attitudes and enable professional handling of IPV we suggest more IPV education that problematizes IPV from a gender perspective in nursing programmes globally. Clinical significance: To improve nursing educations concerning IPV more attention needs to be given IPV and the correlation between IPV and the gendered power structure.

Previous issue date: 2013-01-10The core competencies approach is a tool of business strategic management, constantly being object of study in business administration. However, the operationalization of the concepts which allow its identification, evaluation, classification and practical deployment to the business world keep as challenges to be overcome. Through a qualitative case study with a descriptive and exploratory approach and the analysis of Wilson Sons Shipping Agency, this study sought to contribute to theoretical and practical development of the theme. Therefore, a Framework was developed to evaluate the organizational competencies, containing an identification method, an analysis about the Performance, Sustainability and Organization (P.S.O) of the competence, a competence classification (non strategic, embryonic, basic, differentiated or essential), as well as the elaboration of a systemic map of the competence. As result obtained from the application of the Framework, it is highlighted the identification of the competence differentiated in provide information and solutions in WSAM. The analysis of the main parameters of evaluation reveals the evolutionary history of the company competence and the present context experienced, a development proposal of to broaden its classification to an essential level, as well as the interaction of its components through systemic architecture

Se propone un framework utilizando un componente de pre-procesamiento y MARS para obtener una predicción de ventas de forma precisa y confiable reduciendo el tiempo y costos. Para ello lo primero que se realizo fue obtener las ventas mensuales de los productos “Resorte Toy Corolla” y “Resorte Toy Corolla Gasol” de una empresa llamada “Franco” dedicada a la venta de autopartes, luego se procesó esta información con un componente de pre-procesamiento en donde se detectó y elimino valores atípicos. Posteriormente se seleccionó las variables de predicción y la variable objetivo, por último se construyó los modelos de predicción y se calculó las medidas de error con la ayuda del software "Salford Predictive Modeler 8.0". Luego de realizar las pruebas se llegó a la conclusión que el framework propuesto se ajusta mejor a las necesidades de una pyme ya que se obtiene predicciones de ventas más precisas. Por otro lado no es necesario que el usuario sea un experto ni que tenga conocimientos muy avanzados con respecto a las técnicas o métodos de predicción, porque cuando usamos el software “Salford Predictive Modeler 8.0”, esta misma selecciona las variables de predicción más importantes y crea el modelo de predicción con sus respectivas funciones base además también se encarga del cálculo de las medidas de error.Tesis
