This research investigates wireless intrusion detection techniques for detecting attacks on IEEE 802.11i Robust Secure Networks (RSNs). Despite using a variety of comprehensive preventative security measures, the RSNs remain vulnerable to a number of attacks. Failure of preventative measures to address all RSN vulnerabilities dictates the need for a comprehensive monitoring capability to detect all attacks on RSNs and also to proactively address potential security vulnerabilities by detecting security policy violations in the WLAN. This research proposes novel wireless intrusion detection techniques to address these monitoring requirements and also studies correlation of the generated alarms across wireless intrusion detection system (WIDS) sensors and the detection techniques themselves for greater reliability and robustness. The specific outcomes of this research are: A comprehensive review of the outstanding vulnerabilities and attacks in IEEE 802.11i RSNs. A comprehensive review of the wireless intrusion detection techniques currently available for detecting attacks on RSNs. Identification of the drawbacks and limitations of the currently available wireless intrusion detection techniques in detecting attacks on RSNs. Development of three novel wireless intrusion detection techniques for detecting RSN attacks and security policy violations in RSNs. Development of algorithms for each novel intrusion detection technique to correlate alarms across distributed sensors of a WIDS. Development of an algorithm for automatic attack scenario detection using cross detection technique correlation. Development of an algorithm to automatically assign priority to the detected attack scenario using cross detection technique correlation.

The annual budget cycle in urban road/transport authorities by implication requires transport infrastructure projects to be ranked in terms of their relative value, to enable project selection by starting from the most deserving proposal. This follows from the fact that the total cost of feasible projects practically always exceeds available funds, signalling the need for some kind of selection protocol. Cost benefit analysis (CBA), when applied in a narrow sense, is not suitable for this purpose as it focuses on economic efficiency only. Attempts to broaden it have been criticized by some scholars. Although the diversity of impacts points to a multi-criteria analysis (MCA) approach, this is considered unscientific in certain quarters; at best, its practical value needs to be demonstrated. In the case of the City of Tshwane (CoT), problems with current project appraisal are evident in that different methods – none of which is defensible – are used, sometimes resulting in rankings that are contradictory. This thesis therefore attempts the following: (a) to develop a basic approach that combines the best elements of traditional methods; (b) to customize this approach to the specific context and needs of road authorities in the municipal sphere of government, using CoT as an example; and (c) to demonstrate the application of the resulting appraisal framework, utilizing appropriate decision-support software for this purpose. Recommendations include the following: An appraisal framework should combine CBA and MCA by adopting an overall MCA approach with economic efficiency – focusing on the optimal allocation of scarce resources – as one of the decision criteria. For completeness‟ sake, three additional decision criteria are deemed necessary: equity (focusing on income distribution impacts); sustainability (focusing on environmental impacts); and compatibility (focusing on the alignment of projects with stated goals and objectives). This framework may well apply to road authorities in other spheres of government – the optimum application in each case will depend on the composition of the relevant decision-making team. The inherent nature of project appraisal requires a two-phased approach in all cases: the evaluation of mutually exclusive alternatives, followed by the ranking of independent projects. State-of-the-art decision support software is indispensable for implementing this framework. / Transport Economics / D. Com. (Transport Economics)

Le milieu hospitalier est un monde à la fois sensible et complexe, sensible parce que la vie humaine est en jeu et complexe parce que les équipements médicaux augmentent en nombre et en complexité technique. Ainsi, afin de préserver le bon état de fonctionnement de ces équipements et à un niveau élevé de disponibilité, leur entretien est devenu l'une des préoccupations majeures des responsables de l’hôpital. L’objectif de cette thèse est de proposer, aux responsables de maintenance biomédicale dans les établissements de soins, des outils d’aide à la décision qui permettent une meilleure maitrise des coûts. Ceci en assurant la sécurité des patients et des utilisateurs et en maintenant des performances optimales de l’ensemble des équipements médicaux. Tout d’abord, une heuristique a été proposée pour le choix de l’internalisation ou de l’externalisation de la maintenance et pour la sélection du contrat adéquat. La sélection du contrat est basée sur un ensemble de critères tout en considérant la contrainte du budget disponible. Ensuite, afin d’améliorer la procédure proposée, nous avons proposé des outils d’aide à la décision multicritère pour le choix adéquat d’une stratégie de maintenance. Pour l’étude de la criticité des équipements médicaux et le choix de la maintenance, sept critères ont été étudiés en proposant un couplage de l’approche AHP « Analytical Hierarchy Process » à la technique TOPSIS « Technique for Order Performance by Similarity to Ideal Solution ». Comme les experts du service de maintenance présentaient une certaine incertitude dans leurs jugements, nous avons intégré l’évaluation linguistique floue dans l’étude de la criticité des équipements et dans la sélection de la stratégie de maintenance (Fuzzy AHP couplée avec Fuzzy TOPSIS). Un modèle mathématique MILP a été développé pour la définition des limites de la criticité afin de caractériser les trois stratégies de maintenance. Le bon choix de ces limites permet d’optimiser le coût de la maintenance en respectant le budget disponible. Enfin, un deuxième modèle mathématique MILP a été développé en se basant sur l’heuristique proposée. Ce modèle permet de sélectionner pour chaque équipement, la stratégie de maintenance, internaliser ou externaliser la maintenance et le type du contrat tout en considérant le budget disponible et la charge/capacité du service maintenance / The hospital is a world that is both sensitive and complex, sensitive because the human life is involved and complex because medical facilities are growing in number and in technical complexity. Then, the problem of the medical equipment maintenance in order to keep them in safe, reliable and with high level of availability has become a major preoccupation of the hospital. The objective of this thesis is to provide tools to help the biomedical maintenance service of the hospital to make decisions that allow a better control of costs, while ensuring patient and user safety and maintaining optimal performance of medical equipment. First, a heuristic has been proposed for the choice of internalization or outsourcing maintenance and for the selection of the appropriate contract. The selection of the contract is based on a set of criteria while considering the available budget constraint. Then, to improve the proposed procedure, we proposed multi-criteria decision-making tools to select the appropriate maintenance strategies. Seven criteria have been designed to study the criticality of medical equipment and the choice of maintenance by providing a coupling of the AHP approach "Analytical Hierarchy Process" with TOPSIS technique "Technique for Order Performance by Similarity to Ideal Solution." As the expert judgments of the maintenance department presented some uncertainty, we integrated the fuzzy language assessment of the criticality of the equipment and the selection of the maintenance strategy (Fuzzy AHP coupled with Fuzzy TOPSIS). A mixed integer linear programming model (MILP) was developed to define thresholds of criticality to characterize the three maintenance strategies. According to these thresholds, maintenance cost can be optimized within the available budget. Finally, a second mixed integer linear programming model (MILP) was developed based on the proposed heuristic. This model allows selecting for each equipment, the maintenance strategy, the internalization or the outsourcing of the maintenance and the type of contract while considering the available budget and the workload / capacity of the maintenance department

The tool was used in a lower hierarchical level to identify the projects to be executed with better success, aiming to maximize revenue. The model was tested in a electromechanical industry located in northwest of Rio Grande do Sul, where it was randomly selected six projects with engineering and custom manufacturing(ETO and MTO) among twenty projects that are executed in average per month. As a result, it was obtained the projects analyzed according to criteria adopted, which should be prioritized in production without compromising delivery time to the customer and the earnings of the company. Therefore, one can conclude that the tool can assist in prioritization of project execution type (ETO and MTO). / A presente dissertação tem por objetivo desenvolver um modelo de decisão de sequenciamento de atividades de produção para otimizar o tempo de entrega de projetos. A pesquisa classifica-se como aplicada e descritiva com abordagem qualitativa e quantitativa, tendo como procedimento o estudo de caso único. Para o desenvolvimento do modelo de decisão foi utilizado o mapeamento de fluxo do processo para a identificação dos pontos críticos de controle e determinação dos critérios de avaliação e priorização das atividades de projetos para cada subprocesso. Depois, foram mensurados todos os critérios de avaliação identificados através de fórmulas matemáticas e posteriormente foi elaborada uma ferramenta de simulação de priorização e decisão em múltiplos projetos a fim de sequenciar as atividades de produção. A base de construção da ferramenta de simulação foi o software aplicativo Excel®. A ferramenta foi utilizada num nível hierárquico inferior para identificar os projetos a serem executados com melhor êxito, visando maximizar o faturamento. O modelo foi testado numa indústria eletromecânica do Noroeste do Rio Grande do Sul, onde foi selecionado aleatoriamente seis projetos com engenharia e produção sob encomenda (ETO e MTO) de uma média de vinte projetos que são executados por mês. Como resultado, obtevese dos projetos analisados, de acordo com critérios adotados, qual deveria ser priorizado na produção sem comprometer o prazo de entrega ao cliente e o faturamento da empresa. Portanto, pode-se concluir que a ferramenta pode auxiliar na priorização de execução de projetos do tipo (ETO e MTO).

A necessidade de investimento em saneamento no Brasil é essencial, pois está vinculada à melhoria da qualidade de vida da sociedade. Os projetos de saneamento exigem altos investimentos e, para garantir a prestação dos serviços, é necessário um sistema complexo de infraestrutura. Os elevados custos envolvidos e a limitação de recursos financeiros fazem com que seja preciso estabelecer prioridades para execução de projetos de saneamento. Com efeito, o objetivo desta pesquisa é propor um modelo multicritério de decisão para apoiar decisões de hierarquia de projetos de abastecimento de água e esgotamento sanitário. A pesquisa abordada tem enfoque qualitativo, sendo também vista como metodológica, pois sua finalidade é envolver métodos e procedimentos adotados como científicos. Assim, traz como escopo apoiar e estruturar o processo de decisão em que são definidos: os elementos (intervenientes, alternativas potenciais, critérios, problemática); tipos de decisão em grupo; escolha dos métodos multicritérios (PROMETHEE II & GAIA e ELECTRE IV); modelagem de preferência; sistemas de apoio à decisão (D-SIGHT e ELECTRE III-IV); avaliação de resultados e análise de sensibilidade. Procura-se garantir que a pesquisa tenha caráter prático, razão por que foi realizada a aplicação numérica do modelo no contexto da bacia dos rios Piracicaba, Capivari e Jundiaí, região sudeste do Brasil. / The need of investment in water supply and sewage projects in Brazil is substantial to improve the quality of life.

In the face of these threats, the development of systematic planning which indicates the most important biodiversity conservation areas has become widely accepted. The establishment of protected areas is the main strategy for the protection of biodiversity and maintenance of ecosystem processes due to its feasibility and economic cost. However, species distribution can be altered by global climate change and, possibly, the current network of protected areas may not be sufficient for species representation in future scenarios. The impact of climate change on biodiversity can be anticipated by spatial prioritization for conservation through the development of dynamic conservation plans. However, it is clear that some species have a more important ecological role than others (due to their biological and life history characteristics) which includes the unique challenge of taking an integrated view of biodiversity in conservation planning into account. The Atlantic Forest is a lush biome which holds 7.7% of the world's known species of amphibians and high concentration of endemic species. However, the Atlantic Forest is also one of the most threatened tropical biomes of the world, mainly due to the loss and fragmentation of natural habitats. This thesis provides proposals for conservation efforts, considering the possible effects of climate change and also the wider aspects of biodiversity. For this, I used the available amphibian data from the Red List of Threatened Species of the International Union for Conservation of Nature, available climate models, information on protected areas by the World Database on Protected Areas, and attributes of species and the phylogenetic tree consistent with specific literature. Chapter 1 highlights a discussion on the impact of climate change and priorities for biodiversity conservation and the importance of including the functional and phylogenetic diversity in conservation efforts. Chapter 2 brings a discussion about available data for conservation studies, as well as the advantages and disadvantages of using maps of extent of occurrence in systematic planning for conservation. Chapter 3 shows the effectiveness of protected areas in maintaining species richness under climate change from consensual projections of species distribution models for amphibians inhabiting of the Atlantic Forest. In this chapter, we identified that protected areas may gain or lose species due to climate change according to the location of the current network of protected areas. Chapter 4 presents an alternative approach to complement the existence of protected areas and incorporates possible changes in species distribution. The prioritization is based mainly on the distribution of species in both present and future scenarios. This chapter outlines a conservation plan that minimizes the effects of climate change on species dispersion. Besides these effects on species dispersion, this solution also minimizes the uncertainty associated with distribution models and prioritizing areas of low uncertainty. Chapter 5 explains the spatial prioritization of conservation, including different aspects of biodiversity, such as: phylogenetic & functional diversity measures and their influence on evolutionary history and underlying ecological processes. The main objective is to identify and compare the places that contain the most information on the taxonomic, phylogenetic and functional diversity, while also indicating the conservation priorities for each biogeographical region of the Atlantic Forest. In conclusion, we present our new and original ideas for conservation and discuss the future prospects and predictions in this area. / Processos globais como a perda de habitat, a superexploração, a invasão de espécies exóticas e as mudanças climáticas estão conduzindo muitas espécies à extinção. Nesse contexto, o desenvolvimento de um planejamento sistemático que indique as áreas mais importantes para a conservação da biodiversidade tem sido amplamente aceito. O estabelecimento de áreas protegidas é a principal estratégia para proteção da biodiversidade e a manutenção dos processos ecossistêmicos devido à viabilidade e ao custo econômico. Todavia, a distribuição das espécies pode ser alterada pelas mudanças climáticas global e, possivelmente, a atual rede de áreas protegidas pode não ser suficiente para representar as espécies no futuro. A priorização espacial para a conservação pode antecipar os impactos das mudanças climáticas sobre a biodiversidade, além de mitigar tais impactos por meio do desenvolvimento de planos dinâmicos de conservação. No entanto, é evidente que algumas espécies têm um papel ecológico mais importante que outras devido às suas características biológicas e à história de vida, portanto, um novo desafio é adotar uma visão integrada da biodiversidade no planejamento da conservação. A Mata Atlântica é um exuberante bioma que detém 7,7% das espécies de anfíbios conhecidas do mundo e grande concentração de espécies endêmicas. Contudo, a Mata Atlântica é também um dos biomas tropicais mais ameaçados do mundo, sobretudo devido à perda e fragmentação dos hábitats naturais. Esta tese fornece propostas para os esforços de conservação, considerando os possíveis efeitos das mudanças climáticas e também os amplos aspectos da biodiversidade. Para tanto, utilizei os dados de anfíbios disponíveis na Lista Vermelha de Espécies Ameaçadas da União Internacional para a Conservação da Natureza para toda a Mata Atlântica,modelos climáticos disponíveis e informações sobre áreas protegidas oferecidas pelo World Database on Protected Areas. Os atributos das espécies e a árvore filogenética estão de acordo coma literatura específica. O capítulo 1 apresenta uma discussão sobre os impactos das mudanças climáticas e as prioridades para a conservação da biodiversidade. Ainda, é discutida a importância de incluir a diversidade funcional e filogenética nos esforços de conservação. O capítulo 2 apresenta os tipos de dados disponíveis para estudos de conservação, além das vantagens e das desvantagens do uso de mapas de extensão de ocorrência no planejamento sistemático para a conservação. O capítulo 3 apresenta a avaliação da eficiência das áreas protegidas em manter a riqueza de espécies no contexto de mudanças climáticas a partir de projeções consensuais dos modelos de distribuição das espécies para anfíbios da Mata Atlântica. Essa avaliação identifica se uma área protegida poderá ganhar ou perder espécies devido às mudanças climáticas considerando a localização da rede atual das áreas protegidas. O capítulo 4 apresenta uma abordagem alternativa para complementar a atual rede de áreas protegidas e incorpora as possíveis mudanças na distribuição das espécies. A priorização baseia-se, principalmente, na distribuição das espécies tanto no presente quanto no futuro e busca minimizar os efeitos dessa mudança na distribuição das espécies a partir de uma medida de dispersão no contexto de mudanças climáticas. Além da medida de dispersão, a solução também minimiza a incerteza associada aos modelos de distribuição, priorizando locais de baixa incerteza. O capítulo 5 apresenta a priorização espacial da conservação, incluindo diferentes aspectos da biodiversidade tal como a diversidade filogenética e funcional cujas medidas inferem tanto a história evolutiva quanto os processos ecológicos subjacentes. O principal objetivo é identificar e comparar os locais que conservam a maior informação sobre a diversidade taxonômica, filogenética e funcional quanto possível. Além disso, são indicadas as prioridades para a conservação para cada região biogeográfica da Mata Atlântica. Finalmente, em sua conclusão, são apresentadas as principais novidades da tese e discutidos os rumos para futuros trabalhos.

Para isso, esta pesquisa tem como objetivos específicos registrar qual a percepção dos gestores quanto à importância e o desempenho dos seus papéis, registrar quais tipos de atividades de inovação são promovidos pelos gestores sob a ótica de cada um dos seus papéis, analisar todas as variáveis de forma cruzada e criar um índice de coerência na promoção das atividades de inovação. A metodologia utilizada é um estudo de caso, com levantamento de informação feito por meio de questionário com perguntas fechadas. Foram feitas análises quanto aos tipos de atividades mais frequentes, aos tipos de atividades por cada papel do gestor, à importância de cada responsabilidade dos gestores, ao desempenho de cada responsabilidade dos gestores e ao desempenho em conjunto com a importância. Por fim, conclui-se que os gestores desta empresa não se comportam exatamente como esperado pela literatura. Este comportamento cria a oportunidade de se propor uma metodologia para que os gestores avaliem periodicamente suas responsabilidades e promovam as atividades de inovação necessárias de modo a maximizar sua coerência. / The aim of this study is to analyze how the performance of leadership and the importance of their roles can influence the promotion of organizational innovation activities. To do this, this research has the following specific objectives: registering the perception of managers on the importance and performance of their roles, record which types of innovation activities are promoted by managers from the perspective of each of their roles, analyze all the variables crosswise and create a consistency index in the promotion of innovation activities. The methodology used is a case study with information from survey through a questionnaire made of closed questions. Analyses were made for the most frequent types of activities, types of activities for each role of the manager, the importance of each one of manager’s responsibilities, the performance of each manager’s responsibilities and the performance together with the importance. Finally, it is concluded that managers of this company do not behave exactly as expected by literature. This behavior creates the opportunity to propose a methodology for managers periodically evaluate their responsibilities and promote the necessary innovation activities in order to maximize their coherence.

El desarrollo de la presente tesis forma parte de un estudio realizado en una empresa que brinda servicios de mantenimiento y reparación de motores eléctricos para minería, industria y generación de electricidad. La tesis tiene como finalidad proponer un modelo de gestión que permita agilizar el tiempo de reparación de motores eléctricos de corriente continua, debido a que los clientes se vienen quejando por incumplimientos en la fecha de entrega del servicio, esto genera pérdida de credibilidad, imagen de la empresa y futuros negocios. Para remediar la problemática se utilizaron herramientas de mejora continua tales como análisis de Pareto, espina pescado, 5 por qué y matriz de priorización para determinar el estado actual del servicio de reparación de motores y determinar cuál será nuestro foco para la investigación, basado en este diagnóstico se ha establecido un estándar en la nomenclatura de actividades de un servicio completo de reparación de motor y se implementó un análisis de muestreo de trabajo para determinar el tiempo de estas actividades sin cabida a los tiempos improductivos. Una vez determinado los tiempos se implementó la Hoja de Ruta la cual sirve de fuente para el seguimiento y supervisión más exacta de las actividades durante la ejecución del servicio y de esta manera cumplir con el tiempo de entrega prometido al cliente. El modelo propuesto logra disminuir el tiempo de ejecución de un servicio completo de motor eléctrico del tipo CC en un 17%, así mismo se obtuvo un incremento significativo en nuestro indicador de cumplimiento con la fecha de entrega pactada y una disminución de quejas de los clientes. The development of this thesis is about of a company that provides maintenance and repair services of electric motors for mining, industry and electricity generation. The thesis aims to propose a management model that allows speed up the repair time DC electric motors, because customers have been complaining about violations on the date of delivery of the service, which entails loss of credibility, image of the company and future business. To remedy the problems we used quality tools such as Pareto analysis, fishbone, 5 why’s and prioritization matrix to determine the current state of the service engine repair and determine what will be our focus for research, based on this diagnosis it has set a standard in the nomenclature of activities of a full-service repair, also Work sampling was used to determine the time to accommodate these activities without downtime. Once determined the times we set the Roadmap which serves as a source for more accurate monitoring and supervision of the activities during the execution of the service and thus meet the promised delivery time to the customer was implemented. It managed to reduce the execution time of a full service type DC electric motor by 17%, also a significant increase was obtained in our indicator of compliance with agreed delivery date and a decrease in customer complaints.

Face à l’érosion globale de la biodiversité des écosystèmes aquatiques continentaux, l’identification des mesures de gestion les plus urgentes à mettre en place est cruciale. En s’appuyant sur une approche innovante et multi-facettes de la diversité, les priorités de conservation pour les assemblages de poissons de rivière ont pu être déterminées à l’échelle de la France. La durabilité de ces priorités de conservation face aux principales composantes des changements globaux a ensuite été évaluée afin d’identifier les zones qui protégeront efficacement la biodiversité actuelle dans le futur. La méthodologie développée a finalement été appliquée au réseau hydrographique du département du Pas-de-Calais dans le but d’identifier précisément les priorités locales de conservation et de restauration. Ces outils pourront par la suite être utilisés comme support d’aide à la décision et adaptés selon les besoins des gestionnaires des milieux aquatiques. / The global loss of biodiversity affects freshwater ecosystems, making it crucial to identify the priority management actions in order to protect freshwater biodiversity in an effective and sustainable way. Based on an innovative multi-faceted framework of diversity, the spatial priorities for the conservation of stream fish assemblages have been identified at the scale of France. Their robustness to several drivers of global changes has then been assessed to identify the areas that are likely to efficiently protect the present-day biodiversity in the future. The methodological framework proposed herein has finally been applied to the river network of the Pas-de-Calais department located in northern France to accurately identify the local conservation and restoration priorities. These management tools can be used to support the establishment of management actions in accordance with the needs of the local environmental decision-makers.
