The importance of communication is vital in wartime. The capability of having all the position information of the allied and enemy forces in a single Tactical Information Display System (TIDS), maintains a great advantage for deciding what to do before the enemy reacts. A Naval Information Distributing System (NIDS) is developed for building an effective communication infrastructure between the war ships. In the designed network, besides the mobile platforms (ships), some fixed platforms (land stations) are used to transfer the information coming from these mobile platforms to all the other platforms. To demonstrate the performance and effectiveness of the Naval Information Distribution System, a discrete event simulation model is developed on a Geographic Information System. The goal of this thesis is to describe and experimentally evaluate an effective and feasible information sharing and routing system for Navy.

Peer to peer systems have been widely used in the internet. However, most of the peer to peer information systems are still missing some of the important features, for example cross-language IR (Information Retrieval) and collection selection / fusion features. Cross-language IR is the state-of-art research area in IR research community. It has not been used in any real world IR systems yet. Cross-language IR has the ability to issue a query in one language and receive documents in other languages. In typical peer to peer environment, users are from multiple countries. Their collections are definitely in multiple languages. Cross-language IR can help users to find documents more easily. E.g. many Chinese researchers will search research papers in both Chinese and English. With Cross-language IR, they can do one query in Chinese and get documents in two languages. The Out Of Vocabulary (OOV) problem is one of the key research areas in crosslanguage information retrieval. In recent years, web mining was shown to be one of the effective approaches to solving this problem. However, how to extract Multiword Lexical Units (MLUs) from the web content and how to select the correct translations from the extracted candidate MLUs are still two difficult problems in web mining based automated translation approaches. Discovering resource descriptions and merging results obtained from remote search engines are two key issues in distributed information retrieval studies. In uncooperative environments, query-based sampling and normalized-score based merging strategies are well-known approaches to solve such problems. However, such approaches only consider the content of the remote database but do not consider the retrieval performance of the remote search engine. This thesis presents research on building a peer to peer IR system with crosslanguage IR and advance collection profiling technique for fusion features. Particularly, this thesis first presents a new Chinese term measurement and new Chinese MLU extraction process that works well on small corpora. An approach to selection of MLUs in a more accurate manner is also presented. After that, this thesis proposes a collection profiling strategy which can discover not only collection content but also retrieval performance of the remote search engine. Based on collection profiling, a web-based query classification method and two collection fusion approaches are developed and presented in this thesis. Our experiments show that the proposed strategies are effective in merging results in uncooperative peer to peer environments. Here, an uncooperative environment is defined as each peer in the system is autonomous. Peer like to share documents but they do not share collection statistics. This environment is a typical peer to peer IR environment. Finally, all those approaches are grouped together to build up a secure peer to peer multilingual IR system that cooperates through X.509 and email system.

Au delà de la gestion de la qualité, la traçabilité répond à des enjeux stratégiques pour les entreprises. L'évolution technologique propice à une informatisation intensive et la reconfiguration du paysage logistique amènent à considérer la traçabilité, non plus seulement à l'échelle de l'entreprise mais de la supply chain dont le périmètre mouvant ne cesse de s'élargir. Notre recherche s'est ainsi intéressée à la traçabilité totale des supply chains. Définie comme la capacité à assurer le long des supply chains et si possible en temps réel, le suivi des flux physiques couplés aux flux d'informations, des flux financiers, des ressources et des activités, la traçabilité totale apparaît comme un support de pilotage des supply chains. Notre travail découle d'une question de recherche centrale, «quels facteurs expliquent et influencent la concrétisation de la traçabilité totale des supply chains ?», et prend appui sur le secteur agroalimentaire en France. L'analyse est conduite au niveau de l'entreprise (décision) et de la supply chain (mise en oeuvre), elle se base sur une méthodologie qualitative. Ce travail contribue à donner corps au concept de traçabilité totale en identifiant six dimensions fondamentales. Il propose un cadre d'analyse sur les motivations des entreprises à déployer une traçabilité totale et les éléments qui influencent sa mise en oeuvre. Il ressort ainsi que la traçabilité totale est une préoccupation présente dans les entreprises, mais que leurs intérêts sont variés. Des facteurs, favorables (ou non) à sa mise en oeuvre, sont aussi repérés. Ils sont liés aux caractéristiques de l'entreprise, de la supply chain et aux relations inter-organisationnelles. / Traceability is a relevant and up-to-date issue for companies. The main challenges for companies are not only related to quality, they are of concern from a strategic point of view. Changes in technology and the globalization have contributed to develop traceability of supply chains. Indeed, traceability is to be achieved not only at the company level, but also for supply chains, which have been extended. The research focuses of « total traceability of supply chains ». The total traceability can be defined as the ability to monitor, along supply chains and if possible in real time, physical flows and related information and financial flows, as well as resources and activities. The question we tried to answer was: « what are the factors influencing and explaining the implementation of a total traceability of supply chains? ». The research is based on the case of french agri-food sector. We conducted a twofold qualitative analyses; enterprise and supply chain level because the decision is a choice of the company, and the total traceability is organized at the supply chain level. The main contribution is to provide a conceptual framework of the total traceability concept. Six dimensions characterize the concept. Furthermore, we present an analytical framework to identify what are the enablers and which factors explain the implementation of total traceability. It appears that total traceability is a current interest in every interviewed company, but their motivations are diverse. The identified factors that explain the implementation are related to the characteristics of the company, of the supply chain, of the inter-organizational relationships between the actors.

Trata-se de um ambiente dinâmico de informações que reúne características de sistema complexo, convergente, híbrido, e que apresenta grandes desafios para sua implementação e execução. Nesse sentido nos propomos a analisar o SNIIC sob as perspectivas da Ciência da Informação e do Design da Informação, estabelecendo como objetivo geral identificar recursos e subsídios que ampliem as possibilidades de acesso, compartilhamento e apropriação da informação. A pesquisa é classificada como bibliográfica, exploratória, teórico-aplicada, uma vez que se dá a partir de um levantamento bibliográfico com intuito de conhecer e contextualizar os sistemas de informações e indicadores culturais e assim delinear o problema; é exploratória porque tem a própria plataforma como objeto para coleta dos dados, estudo e análise; teórico-aplicada, pois visa estabelecimento de um produto/serviço para melhorar o sistema de busca e recuperação da informação. Os resultados da análise confirmaram o grande potencial da plataforma, mas revelaram algumas dificuldades, tais como: deficiências na produção documental e no sistema de busca e recuperação da informação. O primeiro problema apontado pode ser corrigido com a adoção política arquivística e curadoria digital, com métodos e procedimentos relacionados ao tratamento de documentos arquivísticos eletrônicos que corrijam estas deficiências na produção documental; já com relação ao segundo, indicamos a aplicação prática de um tesauro sobre convertido no modelo Simple Knowledge Organization System (SKOS) em padrão Resouce Description Framework (RDF), com vistas à organização, recuperação e interoperabilidade entre diferentes sistemas de informação e Web Semântica, permitindo que o usuário realize consultas utilizando seu vocabulário de comum uso, provendo assim uma maior acessibilidade às informações mantidas pelo SNIIC. / The National System of Information and Cultural Indicators (SNIIC) is a digital platform created by the federal government as a tool for the National Culture Plan, with the aim to map and aggregate in a single database, information related to Brazilian culture. It is a dynamic environment information that meets complex system characteristics, convergent, hybrid, and that presents great challenges for its implementation and enforcement. In this sense we propose to analyze the SNIIC from the perspectives of Information Science and Information Design establishing the general objective of identifying resources and subsidies that increase the possibilities of access, sharing and appropriation of information. The research is classified as literature, exploratory, theoretical and applied, since it starts from a literature survey in order to understand and contextualize the information systems and cultural indicators and thus outlining the problem; It is exploratory because it has the platform itself as an object for data collection, research and analysis; theoretical and applied, it aims to establish a product / service to improve the system of search and information retrieval. The test results confirmed the great potential of the platform, but had some problems, such as deficiencies in documentary production and search and information retrieval system. The first pointed problem can be fixed with archival policy adoption and digital curation, with methods and procedures related to the processing of electronic archival documents to correct these deficiencies in document production; already with respect to the second, indicate the practical application of a thesaurus on converted the model Simple Knowledge Organization System (SKOS) standard Resouce Description Framework (RDF), with a view to the organization, retrieval and interoperability between different information and Semantic Web systems, allowing the user to perform queries using their vocabulary in common use, thus providing greater accessibility to information maintained by SNIIC.

Moreover, Product Development Process (PDP) is one of the activities in which knowledge management manifests in the most critical form once it had the intense application of the knowledge. As a consequence, this thesis analyzes the knowledge management aiming to improve the PDP and it also proposes a theoretical model of knowledge management. This model uses five steps (creation, maintenance, dissemination, utilization and discard) through the verification of the occurrence of four types of knowledge conversion (socialization, externalization, combination and internalization) that it will improve the knowledge management in this process. The intellectual capital in Small and Medium Enterprises (SMEs) managed efficiently and with the participation of all employees has become the mechanism of the creation and transference processes of knowledge, supporting and, consequently, improving the PDP. The expected results are an effective and efficient application of the proposed model for the creation of the knowledge base within an organization (organizational memory) aiming a better performance of the PDP. In this way, it was carried out an extensive analysis of the knowledge management (instrument of qualitative and subjective evaluation) within the Design department of a Brazilian company (SEBRAE/RN). This analysis aimed to know the state-of-the-art of the Design department regarding the use of knowledge management. This step was important in order to evaluate in the level of the evolution of the department related to the practical use of knowledge management before implementing the proposed theoretical model and its methodology. At the end of this work, based on the results of the diagnosis, a knowledge management system is suggested to facilitate the knowledge sharing within the organization, in order words, the Design department / A gest?o do conhecimento tem recebido grande aten??o dos profissionais que atuam no Processo de Desenvolvimento de Produtos (PDP), pois muitas das atividades deste processo t?m um car?ter criativo e, portanto, dependem fundamentalmente do conhecimento das pessoas que o realizam. Al?m disso, o PDP ? um dos processos onde a necessidade da gest?o do conhecimento se manifesta de forma mais cr?tica devido a intensa aplica??o do conhecimento. Assim, esta disserta??o analisa a gest?o do conhecimento com o objetivo da melhoria do PDP e prop?e um modelo te?rico de gest?o do conhecimento. Este modelo utiliza-se de cinco passos (cria??o, manuten??o, dissemina??o, utiliza??o e exclus?o) atrav?s da verifica??o da ocorr?ncia de quatro tipos de convers?es do conhecimento (socializa??o, externaliza??o, combina??o e internaliza??o) que poder? potencializar a gest?o do conhecimento nesse processo. O capital intelectual nas pequenas e m?dias empresas gerenciado eficientemente e com a participa??o de todos que a comp?e vem se tornando o mecanismo fomentador dos processos de cria??o e transfer?ncia de conhecimento, auxiliando e, conseq?entemente, melhorando o PDP. Os resultados esperados s?o uma efetiva e eficaz aplica??o do modelo proposto para a cria??o da base de conhecimento numa organiza??o (mem?ria organizacional) atingindo, assim, um desempenho no PDP superior ao diagnosticado anteriormente. Desse modo, foi realizado um diagn?stico de gest?o do conhecimento (instrumento de avalia??o qualitativa e subjetiva) no setor de Design do SEBRAE/RN na tentativa de saber o estado da arte do setor com rela??o ? gest?o do conhecimento. Esta etapa ? imprescind?vel para avaliar em que n?vel o setor se encontra com rela??o ?s pr?ticas de gest?o do conhecimento antes de implementar o modelo e sua metodologia. Ao final do trabalho, mediante os resultados do diagn?stico, sugere-se uma ferramenta de gest?o do conhecimento para facilitar o compartilhamento do conhecimento dentro da organiza??o, no caso, do setor

Para essa investigação, realizou-se uma pesquisa quantitativa com dados coletados de 173 extensionistas através de questionário estruturado (online), buscando averiguar os diferentes níveis de apropriação do SIGProj, suas implicações e impactos individuais e institucionais, descrevendo elementos envolvidos nos resultados. A fundamentação teórica abordou três grandes temas: Mudanças Organizacionais, Tecnologias nas Organizações e Universidades Públicas Brasileiras, detalhando sobre Inovação tecnológica, Sistemas de informação, Extensão Universitária e sua Sistematização. O presente trabalho evidenciou a relevância em estudar fenômenos que envolvem a interação entre tecnologias e organizações, em diferentes níveis de análises, verificando como essas tecnologias, recorrentemente reforçam e transformam configurações estruturais da organização, fazendo destaque à Hipercultura como viabilizadora da incorporação e domínio das tecnologias digitais. Com respeito ao tratamento dos dados, realizaram-se análises estatísticas descritivas e inferenciais auxiliadas pela Teoria das Facetas. Os objetivos foram atendidos e as hipóteses foram adequadamente confirmadas, onde características hiperculturais dos extensionistas mostram-se relevantes para a apropriação de uma ferramenta tecnológica, bem como, diferentes formas de apropriação, determinam diferentes práticas na microdinâmica estudada. Dois importantes achados indicaram que a delegação pode apresentar tanto efeito positivo, quanto negativo, a depender do nível de apropriação do indivíduo e que, o uso da ferramenta em situação cumulativa de papeis aumenta o nível dessa apropriação. Considerações finais e recomendações enfatizam a necessidade de melhores interações com a tecnologia digital, a fim de propiciar melhoria nos resultados. / The present work has proposed to research aspects as result of the adoption of a Management Information System, namely SIGProj in the context of The University Extension at UFPE, having as basis the premises of Theory of Cognitive Mediation and the Sociomateriality perspective. In order to conduct the investigation, a quantitative survey was performed by gathering data from 173 members of The Department of Extensão through an online-based structured questionnaire, aiming to explore the different appropriation levels of the SIGProj, its implications, as well as the individual and institutional impacts, thus describing the elements involved in the results. The theoretical foundation addressed three major themes: Organizational Change, Technologies in Organizations and Brazilian Public Universities, while providing details related to the Technological Innovation, Information Systems, University Extension and its Systematization. The present work evidenced the relevance of studying phenomena that encompass the interaction between technologies and organizations at different levels of analyses, by verifying how these technologies recurrently reinforce and transform structural configurations of the organization, with particular emphasis on the Hyperculture as enabler of the assimilation and know-how of the digital technologies. With regard to data processing, descriptive and inferential statistics analysessupported by the Teoria das Facetas were performed. The objectives were accomplished, as well as the hypotheses were properly ratified. Hypercultural characteristics of Extension members evidenced their relevance for the appropriation of a technological tool, as well as different forms of ownership determine different practices in the micro-dynamics covered in the study. Two important findings indicated that the delegation may have positive effects, or negative, depending on the individual mastery level and that the use of the tool in cumulative situation of roles increases the level of this mastery. Conclusions and recommendations emphasize the need for better interaction with digital technology in order to provide improved results.

Diante da escassez quantitativa e qualitativa da água para atender aos múltiplos usos, pressões legais e institucionais têm exigido que os municípios aí localizados tratem os esgotos municipais, com intuito de preservar e recuperar a qualidade da água dos principais mananciais superficiais utilizados para abastecimento público. Nesse contexto, o reúso mostrase como uma alternativa para atender as demandas menos restritivas quanto à qualidade da água, permitindo que o efluente tratado proveniente de novas estações e atuais de tratamento de esgoto (ETE) possa ser aplicado para fins não-potáveis. O escopo deste trabalho avaliou a viabilidade do reúso do efluente tratado da ETE Piçarrão. De acordo com dados disponibilizados pela estação, foi possível avaliar as características qualitativas do efluente tratado, delimitando as possíveis aplicações, de acordo com normas e padrões internacionais. Com o auxilio de um sistema de informações geográficas (SIG) e dos métodos multicriteriais: Compromise Programming (CP) e o Cooperative Game Theory (CGT) foi definida uma hierarquia entre as alternativas localizadas na bacia de esgotamento da ETE, baseada nos aspectos ambientais, técnicos, econômicos e legais. Trata-se de um suporte à tomada de decisão para o gerenciamento dos recursos hídricos no espaço urbano, aplicável às outras estações de tratamento de esgoto existentes ou previstas no município de Campinas, São Paulo / Abstract: The city of Campinas, which is inserted in one of the most developed areas of the state of São Paulo, faces crises due to use of the water - One of the well-known conflicts of the metropolitan area of São Paulo. Due to the quantitative and qualitative shortage of water assisting to multiple uses, legal and institutional pressures have been demanding that the municipal districts located there treat the city sewers, intending to preserve and to recover the quality of the main superficial spring waters used for public provisioning. In that context, the reuse is shown as an alternative to assist the less restrictive demands related to the quality of the water, allowing the treated effluent originated from new and current stations of sewer treatment (ETE) be applied for no-drinkable ends. The mark of this work evaluated the viability of the reuse of ETE Piçarrão's treated effluent. According to data provided by the station, it was possible to evaluate the qualitative characteristics of the treated efluente, delimiting the possible applications, according to international norms and patterns. With the aid of a system of geographical information (SIG) and of the multi-criteria methods: Compromise Programming (CP) and Cooperative Game Theory (CGT) was classified among the options located in the basin of exhaustion of ETE based on the environmental, technical, economical and legal aspects. This is about a support to thedecision-making for the administration of water resources in the urban space applicable to the other stations of sewer treatment existent or predictable in the city of Campinas, São Paulo / Doutorado / Saneamento e Ambiente / Doutor em Engenharia Civil
