Повний текст джерелаA major feature of the human eye is the compressed sensitiveness of the retina. An image coder, which makes use of this, can heavily encode the parts of the image which is not close to the focus of our eyes. Existing image coding schemes require that the gaze direction of the viewer is measured. However, a great advantage would be if an estimator predicts the focus of attention (FOA) regions in the image.
This report presents such an implementation, which is based on a model that mimics many of the biological features of the human visual system (HVS). For example, it uses a center-surround mechanism, which is a replica of the receptive fields of the neurons in the HVS.
An extra feature of the implementation is the extension to handle video sequences, and the expansion of the FOA:s. The test results of the system show good results from a large variety of images.

It is important for companies to manage their revenues and -reduce their costs efficiently. These goals can be achieved through effective pricing and inventory control strategies. This thesis studies a joint multi-period pricing and inventory control problem for a make-to-stock manufacturing system. Multiple products are produced under shared production capacity over a finite time horizon. The demand for each product is a function of the prices and no back orders are allowed. Inventory and production costs are linear functions of the levels of inventory and production, respectively. In this thesis, we introduce an iterative gradient-based algorithm. A key idea is that given a demand realization, the cost minimization part of the problem becomes a linear transportation problem. Given this idea, if we knew the optimal demand, we could solve the production problem efficiently. At each iteration of the algorithm, given a demand vector we solve a linear transportation problem and use its dual variables in order to solve a quadratic optimization problem that optimizes the revenue part and generates a new pricing policy. We illustrate computationally that this algorithm obtains the optimal production and pricing policy over the finite time horizon efficiently. The computational experiments in this thesis use a wide range of simulated data. The results show that the algorithm we study in this thesis indeed computes the optimal solution for the joint pricing and inventory control problem and is efficient as compared to solving a reformulation of the problem directly using commercial software. The algorithm proposed in this thesis solves large scale problems and can handle a wide range of nonlinear demand functions.

Повний текст джерелаO desenvolvimento de novos produtos é atualmente uma forte aposta das empresas na busca de envolver novos eixos e nichos de mercado, através da inovação, capaz de promover produtos adequados às necessidades mais eminentes do mercado alvo. O projeto em questão, teve lugar no seio do Grupo Derovo, com o objetivo fundamental de desenvolvimento de um ovoproduto líquido pasteurizado à base de gema de ovo (ingrediente crucial e maioritário) específico para a produção de fios de ovos, cuja adequação pode ser em produtos profissionais industriais, bem como para um consumidor doméstico, pautando-se por ser um produto de fácil utilização e capaz de produzir um resultado de alta qualidade. Tratando-se de um projeto ligado ao desenvolvimento de um novo produto alimentar, este processo contemplou diversas etapas, entre as quais se destacam essencialmente: perceção/compreensão das necessidades inerentes ao mercado; ensaios preliminares; testes de formulação de protótipos e avaliação da sua performance; análise de mercado de protótipos selecionados. Numa primeira fase, realizaram-se alguns ensaios preliminares com o intuito de perceber qual o efeito de diversas etapas do ciclo produtivo da unidade produtiva em questão, acompanhados pela análise de parâmetros físico-químicos (pH; Teor de Sólidos Solúveis (°Brix); Viscosidade (mPa.s); Extrato Seco (%)) e da análise fotográfica. Demonstrou-se efetivamente que a gema de ovo não pasteurizada apresentou resultados notoriamente superiores aos conseguidos com as restantes tipologias estudadas. Após uma procura de agentes tecnológicas no mercado de ingredientes alimentares, iniciou-se a fase de formulação de diversos protótipos, por adição de diversas percentagens (0,1 a 0,03%) e combinações (agentes emulsionantes e/ou agentes texturizantes) tendo posteriormente realizado as análises físico-químicas já referenciadas (incluindo ainda Atividade da água e cor). Seguiu-se a avaliação dos protótipos em desenvolvimento na produção de fios de ovos, através de um controlo de diversos fatores inerentes à sua produção (temperatura da calda de açúcar, entre outros), tendo os resultados finais sido alvo de uma análise fotográfica, análise sensorial (provas de medição do grau de satisfação) e análise microbiológica, com o objetivo de comparar os diversos ensaios e auxiliar na selecção dos protótipos em estudo. Demonstrou-se que a percentagem de 0,03% teve a melhor performance na produção de um fio de ovo com características adequadas, principalmente por aplicação de dois agentes tecnológicos específicos (Jungbunzlauer e DynaVisc), estando igualmente adequada à qualidade exigida pelo mercado.
Development of new food products is currently a strong focus of the companies involved in the search for new ways and niche markets through innovation to promote adequate products to the most eminent needs of our market. This project, developed at the Group Derovo, had as its main objective the development of new egg product mainly constituted by pasteurized liquid egg yolk (crucial and major ingredient) specific for the production of traditional portuguese sweet – “fios de ovos” - to both professionals industrials, and also the household consumer, guided for being a product easy to use and capable of producing a high quality product. Since this is a project linked to the development of a new food product, this process included several steps, among which are important to highlight: understanding of the needs inherent in the market; preliminary tests; formulation testing of prototypes and their evaluation performance; market analysis of selected prototypes. Initially, there were some preliminary tests in order to see what effect various stages of the production cycle of egg production unit in question, followed by analysis of physico-chemical parameters (pH, Total Soluble Solids (°Brix), Viscosity (mPa.s), Dry Matter (%)) and photographic analysis. It was shown that effectively unpasteurized egg yolk was notably greater to the results achieved with other types studied. After a demand on the market of technological agents of food ingredients, several prototypes were formulated by addition of various percentages (0,1 to 0,03%) and combinations (emulsifying agents and/or texturizing agents) and subsequently analyzed from the standpoint of the physicochemical analyses already mentioned (further including Water Activity and color) and the microbiological point of view. This was followed by evaluation of the prototype under development in the production of traditional portuguese sweet – “fios de ovos” - by controlling several factors inherent in their production (temperature sugar syrup, etc.), and the final result was the target of a photographic analysis, sensory analysis (tests measuring the degree of satisfaction) and microbiological analysis in order to compare the different assays as well as aid in the selection of the prototypes in this study. It was demonstrated that the proportion of 0.03% had the better performance in the production of traditional portuguese sweet with suitable characteristics mainly by application of two specific technological agents (Jungbunzlauer e DynaVisc) and is also according to the evaluation made by the market.

Повний текст джерелаIn present manufacturing systems, the current challenge is the development of highly reconfigurable, truly distributed solutions. The tendency is to build manufacturing systems with autonomous, intelligent and distributed components that will support reconfiguration and adaptability. The most promising paradigms for the implementation of such systems are multi-agents and service oriented architectures (SOA), mainly over the DPWS (Device Profile for Web Services) implementation which was aimed at devices. An important limitation of most current multi-agent systems is that the management system is not totally distributed. Failure in the agent responsible for the registry can overthrow the entire system. DPWS does not have this limitation, since the management system is totally distributed. However, DPWS does not support agent autonomy notions as efficiently. The possibility of creating a truly distributed multi-agent system by linking both approaches led to this thesis. A Middleware layer was developed that enables agents to benefit from DPWS functionalities in order to reach the proposed goal. This middleware layer joins agents, databases, hardware, simulators, human interface applications such as production system management, error correction and maintenance, etc. To prove this concept a 3D model of an agent controlled manufacturing system with transporters augmented with DPWS communication interfaces was developed.

In recent years, companies have used Artificial Intelligence (AI) techniques to facilitate the decisionmaking process in manufacturing systems. The use of these techniques allows increased performance of Flexible Manufacturing System (FMS). The automation of the process using computational resources allows a deeper analysis of the system conditions, which sometimes result in a better decision taking. In this sense, the Fuzzy Logic has been engaged to carry out this task, because it has the characteristic of dealing easily with inaccurate information and encoding knowledge specialist in Fuzzy rules. However, as soon as the system complexity increases, the task of generating a Fuzzy Rule Base (FRB) appropriate to the proposed system becomes increasingly difficult. To assist this process of generation of the FRB, several techniques can be used and among them stand out the search technique called Evolutionary Algorithm (EA). The EA is used, for example, for tuning the FRB of the FMS through the reduction of the optimization variables values as Makespan or Tardiness. In the case of variable called Makespan, the tuning occurs when the EA generates an FRB that reduces the makespan values of a FMS. However, the construction of the EA that effectively generates a tuning FRB is not trivial. It is required to be in the process, the construction of various EA with different selection methods and different mutation rates among other settings until an appropriate EA for a given situation appears. Therefore, in this study we aim to build an environment configuration and performance analysis of EAs in order to define the tuning FRB of the Fuzzy Control System of an FMS, i.e., it is intended to investigate how the EA ideal parameter scenario used for tuning the FRB of the said control system. In this study, the used EA was an extension of Genetic Algorithm (GA). For implementing the proposal, an evolutionary system for configuration and analysis of this variant of the GA was created. In this system, entitled "EvolSys - Evolutionary System" parameters of the system as Number of Input Variables of FRB, Number of Output Variables of FRB, Population Size, Mutation Rate and the EA Crossover Rate, among others are configured and then, one FRB is generated. Using this, there is an EA analysis of the possibility for choosing a FRB that will provide the reduction of makespan in FMS. Consequently, through this study, we may conclude that the use of EAs in collaboration with Fuzzy system may become an important tool for turning the system responsibility to the sequences of an FMS operation. Accordingly, the environment created meets the configuration step and analysis of EAs.
Nos últimos anos, empresas tem usado técnicas de Inteligência Artificial (AI) para auxiliar o processo de tomada de decisão em sistemas de manufatura. O uso dessas técnicas possibilita o aumento do desempenho dos Sistemas Flexíveis de Manufatura (FMS), uma vez que a automatização do processo com o uso de recursos computacionais permite uma análise mais profunda das condições do sistema o que, por vezes, resulta em uma melhor tomada de decisão. Neste sentido, a Lógica Fuzzy vem sendo usada para realizar essa tarefa, pois ela tem a característica de lidar facilmente com informações imprecisas, codificando o conhecimento do especialista nas chamadas Regras Fuzzy. Entretanto, à medida que a complexidade do sistema aumenta, a tarefa de gerar uma Base de Regras Fuzzy (FRB) adequada ao sistema proposto se torna cada vez mais difícil. Para auxiliar esse processo de geração da FRB, várias técnicas podem ser usadas e dentre elas destaca-se a técnica de busca denominada Algoritmo Evolutivo (EA). O EA pode ser usado, por exemplo, para a sintonia da Base de Regras Fuzzy do Sistema de Controle de um FMS por intermédio da redução de valores de variáveis de otimização como Makespan ou Tardiness. No caso da variável denominada Makespan, a sintonia ocorre quando o EA gera uma FRB que reduz os valores do makespan do FMS em questão. Entretanto, a construção do EA que efetivamente gera uma FRB sintonizada para um FMS não é trivial, pois é necessário que haja, nesse processo, a construção de vários tipos de EA com métodos de seleção diferentes, taxas de cruzamento e mutação diferentes dentre outras configurações, até que se encontre o EA adequado à uma dada situação. Sendo assim, no presente trabalho, o objetivo é a construção de um ambiente de configuração e análise de desempenho de EAs para sintonia da FRB do Sistema de Controle de um FMS, ou seja, pretende-se investigar qual o cenário de parâmetros ideal do EA usado na sintonia da FRB do referido sistema de controle. No presente trabalho, o EA usado foi uma extensão do Algoritmo Genético (GA). Para implementação da proposta, um Sistema Evolutivo para configuração e análise dessa variante do GA foi criado. Nesse sistema, intitulado “EvolSys - Evolutionary System”, parâmetros dos sistema como Número de Varáveis de Entrada da FRB, Número de Variáveis de Saída da FRB, Tamanho da População, Taxa de Mutação e Taxa de Cruzamento do EA, dentre outros são configurados e, por consequência, uma FRB é gerada. Com isso, há a possiblidade da análise do EA para a escolha de uma FRB que venha propiciar a redução do makespan em FMSs. Portanto, é possível concluir, a partir desse trabalho, que o uso de EAs em colaboração com os sistemas Fuzzy pode vir a se tornar uma importante ferramenta para sintonia da Base de Regras do sistema responsável pelo sequenciamento das operações de um FMS e, nesse sentido, o ambiente criado cumpre a etapa de configuração e análise do desempenho de EAs.

Повний текст джерелаIn the modern society, new devices, applications and technologies, with sophisticated capabilities, are converging in the same network infrastructure. Users are also increasingly demanding in personal preferences and expectations, desiring Internet connectivity anytime and everywhere. These aspects have triggered many research efforts, since the current Internet is reaching a breaking point trying to provide enough flexibility for users and profits for operators, while dealing with the complex requirements raised by the recent evolution. Fully aligned with the future Internet research, many solutions have been proposed to enhance the current Internet-based architectures and protocols, in order to become context-aware, that is, to be dynamically adapted to the change of the information characterizing any network entity. In this sense, the presented Thesis proposes a new architecture that allows to create several networks with different characteristics according to their context, on the top of a single Wireless Mesh Network (WMN), which infrastructure and protocols are very flexible and self-adaptable. More specifically, this Thesis models the context of users, which can span from their security, cost and mobility preferences, devices’ capabilities or services’ quality requirements, in order to turn a WMN into a set of logical networks. Each logical network is configured to meet a set of user context needs (for instance, support of high mobility and low security). To implement this user-centric architecture, this Thesis uses the network virtualization, which has often been advocated as a mean to deploy independent network architectures and services towards the future Internet, while allowing a dynamic resource management. This way, network virtualization can allow a flexible and programmable configuration of a WMN, in order to be shared by multiple logical networks (or virtual networks - VNs). Moreover, the high level of isolation introduced by network virtualization can be used to differentiate the protocols and mechanisms of each context-aware VN. This architecture raises several challenges to control and manage the VNs on-demand, in response to user and WMN dynamics. In this context, we target the mechanisms to: (i) discover and select the VN to assign to an user; (ii) create, adapt and remove the VN topologies and routes. We also explore how the rate of variation of the user context requirements can be considered to improve the performance and reduce the complexity of the VN control and management. Finally, due to the scalability limitations of centralized control solutions, we propose a mechanism to distribute the control functionalities along the architectural entities, which can cooperate to control and manage the VNs in a distributed way.
Na sociedade actual, novos dispositivos, aplicações e tecnologias, com capacidades sofisticadas, estão a convergir na mesma infra-estrutura de rede. Os utilizadores são também cada vez mais exigentes nas suas preferências e expectativas pessoais, desejando conetividade `a Internet em qualquer hora e lugar. Estes aspectos têm desencadeado muitos esforços de investigação, dado que a Internet atual está a atingir um ponto de rutura ao tentar promover flexibilidade para os utilizadores e lucros para os operadores, enquanto lida com as exigências complexas associadas `a recente evolução. Em sintonia com a linha de investigação para a Internet do futuro, muitas soluções têm sido propostas para melhorar as arquiteturas e protocolos da Internet atual, de forma a torná-los sensíveis ao contexto, isto é, adaptá-los dinamicamente `a alteração da informação que caracteriza qualquer entidade de rede. Neste sentido, a presente Tese propõe uma nova arquitetura que permite criar várias redes com diferentes características de acordo com o contexto das mesmas, sobre uma única rede em malha sem fios (WMN), cuja infra-estructura e protocolos são muito flexíveis e auto-adaptáveis. Mais especificamente, esta Tese modela o contexto dos utilizadores, que pode abranger as suas preferências de segurança, custo e mobilidade, capacidades dos seus dispositivos ou requisitos de qualidade dos seus serviços, de forma a transformar uma WMN num conjunto de redes lógicas. Cada rede lógica ´e configurada para satisfazer um conjunto de necessidades de contexto do utilizador (como exemplo, suporte de mobilidade elevada e de baixa seguran¸ca). Para implementar esta arquitetura centrada no utilizador, esta Tese utiliza a virtualização de redes, que tem muitas vezes sido defendida como um meio para implementar arquiteturas e serviços de rede de uma forma independente, enquanto permite uma gestão dinâmica dos recursos. Desta forma, a virtualização de redes pode permitir uma configuração flexível e programável de uma WMN, a fim de ser partilhada por várias redes lógicas (ou redes virtuais - VNs). Além disso, o grau de isolamento introduzido pela virtualização de redes pode ser utilizado para diferenciar os protocolos e mecanismos de cada VN baseada em contexto. Esta arquitetura levanta vários desafios para controlar e gerir as VNs em tempo real, e em resposta `a dinâmica dos utilizadores e da WMN. Neste contexto, abordamos os mecanismos para: (i) descobrir e selecionar a VN a atribuir a um utilizador; (ii) criar, adaptar e remover as topologias e rotas das VNs. Também exploramos a possibilidade de considerar a taxa de variação dos requisitos de contexto dos utilizadores de forma a melhorar o desempenho e reduzir a complexidade do controlo e gestão das VNs. Finalmente, devido ´as limitações de escalabilidade das soluções de controlo centralizadas, propomos um mecanismo para distribuir as funcionalidades de controlo ao longo das entidades da arquitectura, que podem cooperar para controlar e gerir as VNs de uma forma distribuída.

Resumo: A metodologia QFD - Quality Function Deployment, (Desdobramento da Função Qualidade) será apresentada no contexto de um projeto, buscando uma abordagem de desenvolvimento objetiva e seqüencial através de estágios de desenvolvimento de projetos. Algumas teorias sobre as culturas organizacionais e uma forma de analisá-las serão também apresentadas. Baseado nelas, os pressupostos culturais implícitos da metodologia QFD serão identificados, bem como sua relação provável com outros pressupostos compartilhados das organizações brasileiras, revelados por elementos de cultura típicos, inseridos neste mesmo contexto. Como resultado da análise crítica destas relações, pretende-se definir Fatores Críticos de Sucesso (FCS) para que as organizações que utilizam ou desejam utilizar a metodologia QFD, considerem de forma mais ampla as influências das culturas organizacionais e usem os FCS para ajudá-las a ter maior probabilidade de sucesso na implementação de seus projetos de QFD
Abstract: The QFD - Quality Function Deployment methodology will be presented within a project context, using an objective development approach through sequential stages. Some theories about organizational cultures and a method for analyzing them are also presented. Based on these concepts, QFD implicit cultural assumptions will be identified as well as their probable relationship with other shared assumptions of the Brazilian organizations revealed by typical cultural elements, within the same context. As a result of a critical analysis of those relationships, Critical Success Factors (CSF) will be defined so that the organizations that practice or intend to practice QFD, take higher considerations of the influences of the organizational cultures, and use the CSF to help them increase their probability of success on the implementation of QFD projects

In the developed system, by using web pages, one can give work orders to the flexible manufacturing cell in METUCIM. The manufacturing capabilities of the cell are limited by the capabilities of CNC Lathe and CNC Milling machine that exist in the system. By the developed agent based dynamic scheduling method, it is prevented to be only an experimental system for the manufacturing cell.

Повний текст джерелаOne of the best known forms of feeding back a system is through a three-term control law called PID (Proportional-Integral-Derivative) controller. PID controllers are sufficient for many control problems, particularly when process dynamics are not highly nonlinear and the performance requirements are modest. Besides, because of its simple structure, the PID controller is the most adopted control scheme by industry and practitioners, beeing the PI the form mostly employed. Since the PI tuning methods are based on the linearization, commissioning a PI to operate around a single operating point is relatively easy, however, the performance will be below par in wide operating regimes. To overcome this drawback the current practice is to re-tune the gains of the PI controllers based on a linear model of the plant evaluated at various operating points, a procedure known as gain-scheduling. There are several disadvantages of gain-scheduling including the need to switch (or interpolate) the controller gains and the non-trivial definition of the regions in the plants state space where the switching takes place - both problems are exacerbated if the dynamics of the plant is highly nonlinear. In other common scenarios, a little information about the process dynamics or only a "good" linear approximation is taken into account when designing the control design. This impedes to analyse the global stability of the system. In this context, the current thesis work is aimed at the designing of PI controllers, based on the passivity theory, such that the stability of the closed-loop system is guarantied. One of the main advantages of passivity concepts is that they offer a physical and intuitive appeal. The primary idea in passive systems is that the power flowing into the system is not less that the increase of storage. Thus, they cannot store more energy than is supplied to it from the outside, with the difference being the dissipated energy. Thus, introducing the concept of energy, this methodology allows to recast the control problem as finding a dynamical system such that system energy function takes the desired form. Also, with this formulation, the communication between practitioners and control theorists is facilitated, incorporating prior knowledge of the system and providing physical interpretations of the control action. In this thesis, a constructive methodology for deriving PI passivity-based controllers is presented and motivated by the application to physical systems

Повний текст джерелаThese last years, we are witnessing a real digital revolution of Internet where many innovative applications such as Internet of Things, autonomous cars, etc., have emerged. Consequently, adopting externalization technologies such as cloud and fog computing to handle this technological expansion seems to be an inevitable outcome. However, using the cloud or fog computing as a data repository opens many challenges in prospect. This thesis addresses security issues in cloud and fog computing which is a major challenge that need to be appropriately overcomed. Indeed, adopting these technologies means that the users lose control over their own data, which exposes it to several security threats. Therefore, we first investigated the main security issues facing the adoption of cloud and fog computing technologies. As one of the main challenges pointed in our investigation, access control is indeed a cornerstone of data security. An efficient access control mechanism must provide enforced and flexible access policies that ensure data protection, even from the service provider. Hence, we proposed a novel secure and efficient attribute based access control scheme for cloud data-storage applications. Our solution ensures flexible and fine-grained access control and prevents security degradations. Moreover, it performs immediate users and attributes revocation without any key regeneration. Authentication service in fog computing architecture is another issue that we have addressed in this thesis. Some traditional authentication schemes endure latency issues while others do not satisfy fog computing requirements such as mutual authentication between end-devices and fog servers. Thus, we have proposed a new, secure and efficient authentication scheme that ensures mutual authentication at the edge of the network and remedies to fog servers' misbehaviors.Finally, we tackled accountability and privacy-preserving challenges in information-sharing applications for which several proposals in the literature have treated privacy issues, but few of them have considered accountability service. Therefore, we have proposed a novel accountable privacy preserving solution for public information sharing in data externalization platforms. Externalization servers in our scheme authenticate any user in the system without violating its privacy. In case of misbehavior, our solution allows to trace malicious users thanks to an authority

This paper proposes a procedure to control on-line processes for attributes, using an Shewhart control chart with two control limits (warning limit and control limit) and will be based on a sequence of inspection (h). The inspection procedure is based on Taguchi et al. (1989), in which to inspect the item, if the number of non-conformities is higher than an upper control limit, the process needs to be stopped and some adjustment is required; and, if the last inspection h, from all items inspected present a number of non-conformities between the control limit and warning limit. The items inspected will suffer destructive inspection, being discarded after inspection. Properties of an ergodic Markov chain are used to get the expression of average cost per item and the aim was the determination of four optimized parameters: the sampling interval of the inspections (m); the constant W to draw the warning limit (W); the constant C to draw the control limit (C), where W ? C, and the length of sequence of inspections (h). Numerical examples illustrate the proposed procedure

Повний текст джерелаA tecnologia Radio-Frequency Identification (RFID) tem vindo a ser a aposta de muitas empresas para a rastreabilidade industrial devido à sua capacidade de identificação de objetos sem contacto, permitindo que se pratiquem leituras a alguma distância. A sua alta velocidade, comparativamente com outros sistemas, e a sua precisão de aquisição de dados são também características interessantes nestes sistemas. No entanto, verificam-se alguns problemas, tais como: a elevada diversidade de sistemas RFID, as várias frequências de funcionamento (com diferentes aceitações pelo mundo), os vários tipos de acoplamento entre o leitor e a TAG, as várias Normas existentes e a constante atualização da tecnologia que levam a incompatibilidades entre sistemas. A integração de novos sistemas de rastreabilidade de certa forma ajudaria à resolução do problema de incompatibilidade de sistemas, no entanto, verifica-se também uma dificuldade neste ponto. Por isso, nesta dissertação, no âmbito da rastreabilidade industrial conjuntamente com a tecnologia RFID pretende-se criar uma camada intermédia (Middleware) que permita interligar todos os dispositivos presentes no chão da fábrica e que através de uma estrutura de mensagem proposta se possibilite uma comunicação entre camadas superiores e os vários dispositivos da camada inferior. Foi implementada uma camada intermédia numa unidade de processamento que permitiu integrar duas marcas diferentes de dispositivos RFID. Foi desenvolvida uma aplicação de rastreabilidade onde, inclusivamente, se faz o controlo dos dispositivos, direta (Modo Manual) ou indiretamente (Modo Automático) e onde relativamente à incompatibilidade entre sistemas foi desenvolvida uma janela em especial que permite a associação de TAGs internas a produtos que chegam à empresa e que não são compatíveis com o sistema de rastreabilidade (RFID) presente na empresa. Todas as ações efetuadas com esta aplicação (ações de rastreabilidade) são registadas numa Base de Dados (BD) que foi elaborada com base em modelos de rastreabilidade e onde se efetuaram as devidas modificações, procedendo-se à sua normalização. A solução proposta cumpriu com os objetivos. Relativamente à implementação, apesar de ter sido elaborada com base em duas marcas específicas de sistemas RFID, a estrutura do código e a estrutura da mensagem proposta permitem que sejam adicionadas novas secções de código na camada intermédia para novos dispositivos a integrar, continuando com a correta gestão de mensagens entre as camadas superior e inferior.
RFID technology has been affixed to many industrial companies for traceability due to its ability to identify objects without contact, allowing readings with some distance. The high speed and accuracy of data acquisition is also interesting features of this system. However there are some problems such as the high diversity of RFID systems, the various operating frequencies (with different acceptances for the world), the various coupling types between the reader and the TAG, the various existing standards and the constant updating of technology, that lead to incompatibilities between systems. The integration of new traceability systems helps to solve the problem of incompatibility between systems, however there is also a difficulty here. For this reason, in the framework of the industrial traceability along with RFID technology, it is intended, in this dissertation, create an intermediate layer (Middleware), allowing to link all devices present on the factory floor, and through a message structure proposed it allows communication between the upper and lower layer of multiple devices. It was implemented an intermediate layer in a processing unit (microcontroller) that allowed to integrate two different brands of RFID devices. It was developed a traceability application, where it controls the devices directly (Manual Mode) or indirectly (Auto Mode), where on the incompatibility between systems, we developed a special window that allows the combination of internal TAGs to products arriving to the company not compatible with the traceability system (RFID) in this company. All actions taken with this application (traceability actions) are recorded in Data Base, which was developed based on models of traceability and where it was made the necessary changes, proceeding to its standardization. The proposed solution met its goals, and despite the implementation have been developed based on two specific brands of RFID systems, the code structure and message structure proposed to be added to allow new sections of code in the intermediate layer to integrate new devices continuing with the correct management messages between the upper and lower layers.

Повний текст джерелаFunctional electrical stimulation (FES) has the potential to provide active improvement to spinal cord injured (SCI) patients in terms of mobility, stability and side-effect prevention. In the domain of lower limb FES system, elicited muscle force must be provided appropriately to perform intended movement and the torque generation by FES should be accurate not to lose the posture balance. However, muscle state changes such as muscle fatigue is a major cause which degrades its performance. In addition, most of the complete SCI patients don't have sensory feedback to detect the fatigue and in-vivo joint torque sensor is not available yet. Conventional FES control systems are either in open-loop or not robust to muscle state changes. This thesis aims at a development of joint torque prediction and feedback control in order to enhance the FES performance in terms of accuracy, robustness, and safety to the patients.In order to predict FES-induced joint torque, evoked-Electromyography (eEMG) has been applied to correlate muscle electrical activity and mechanical activity. Although muscle fatigue represents time-variant, subject-specific and protocol-specific characteristics, the proposed Kalman filter-based adaptive identification was able to predict the time-variant torque systematically. The robustness of the torque prediction has been investigated in a fatigue tracking task in experiment with SCI subjects. The results demonstrated good tracking performance for muscle variations and against some disturbances.Based on accurate predictive performance of the proposed method, a new control strategy, EMG-Feedback Predictive Control (EFPC), was proposed to adaptively control stimulation pattern compensating to time-varying muscle state changes. In addition, this control strategy was able to explicitly avoid overstimulation to the patients, and conveniently generate appropriate stimulation pattern for desired torque trajectory

Повний текст джерелаTo begin, filling a knowledge gap (Russell 2004), we have performed microeconomic research on the households’ costs-and-consequences-of-tuberculosis in Burkina Faso and Benin. The two case studies have been conducted both in rural and urban resource-poor settings between 2007 and 2009. This thesis provides new empirical findings on the remaining financial, social and ‘healthcare delivery related organizational’ barriers to access diagnosis and treatment services that are delivered free-of-charge to the population. The direct costs associated with illness incurred by the tuberculosis pulmonary smear-positive patients have constituted a severe economic burden for these households living in permanent budget constraints. Most of these people have spent catastrophic health expenditure to cure tuberculosis and, at the same time, have faced income loss caused by the care-seeking. To cope with the substantial direct and indirect costs of tuberculosis, the patients have shipped their families in impoverishing strategies to mobilize funds for health such as depleting savings, being indebted and even selling livestock and property. Damaging asset portfolios of the disease-affected households on the long run, the coping strategies result in a public health threat. In resource-poor settings, the lack of financial protection for health may impose inability to meet basic needs such as the rights to education, housing, food, social capital and access to primary healthcare. Special feature of our work lies in the breakdown of the information gathered. We have been able to demonstrate significant differences in the volume and nature of the amounts spent across the successive stages of the care-seeking pathway. Notably, pre-diagnosis spending has been proved critical both in the rural and urban contexts. Moreover, disaggregated cost data across income quintiles have highlighted inequities in relation to the direct costs and to the risk of incurring catastrophic health expenditure because of tuberculosis. As part of the case studies, the tuberculosis control strategies have failed to protect the most vulnerable care users from delayed diagnosis and treatment, from important spending even during treatment – including significant medical costs, and from hidden costs that might have been exacerbated by poor health systems. To such devastating situations, the tuberculosis patients have had to endure other difficulties; we mean intangible costs such as pain and suffering including stigmatization and social exclusion as a result of being ill or attending tuberculosis care facilities. The analysis of all the social and economic consequences for tuberculosis-affected households over the entire care-seeking pathway has been identified as an essential element of future cost-of-illness evaluations, as well as the need to conduct benefit incidence assessment to measure equity.
This work has allowed identifying a series of policy weaknesses related to the three dimensions of the universal health coverage for tuberculosis (healthcare services, population and financial protection coverage). The findings have highlighted a gap between the standard costs foreseen by the national programs and the costs in real life. This has suggested that the current strategies lack of patient-centered care, context-oriented approaches and systemic vision resulting in a quality issue in healthcare delivery system (e.g. hidden healthcare related costs). Besides, various adverse effects on households have been raised as potential consequences of illness; such as illness poverty trap, social stigma, possible exclusion from services and participation, and overburdened individuals. These effects have disclosed the lack of social protection at the country level and call for the inclusion of tuberculosis patients in national social schemes. A last policy gap refers to the lack of financial protection and remaining inequities with regards to catastrophic health expenditure still occurring under use fee exemptions strategies. Thereby, one year before 2015 – the deadline set for the Millennium Development Goals – it is a matter of priority for Benin and Burkina Faso and many other countries to tackle adverse effects of the remaining social, economic and health policy and system related barriers to tuberculosis control. These factors have led us to emphasize the need for countries to develop sustainable knowledge.
National decision-makers urgently need to document the failures and bottlenecks. Drawing on the findings, we have considered different ways to strengthen local capacity and generate bottom-up decision-making. To get there, we have shaped a decision framework intended to produce local evidence on the root causes of the lack of policy responsiveness, synthesize available evidence, develop data-driven policies, and translate them into actions.
Beyond this, we have demonstrated that controlling tuberculosis was much more complex than providing free services. The socio-economic context in which people affected by this disease live cannot be dissociated from health policy. The implications of microeconomic research on the households’ costs and responses to tuberculosis may have a larger scope than informing implementation and adaptation of national disease-specific strategies. They can be of great interest to support the definition of guiding principles for further research on social protection schemes, and to produce evidence-based targets and indicators for the reduction and the monitoring of economic burden of illness. In this thesis, we have build on prevailing debates in the field and formulated different assumptions and proposals to inform the WHO Global Strategy and Targets for Tuberculosis Prevention, Care and Control After 2015. For us, to reflect poor populations’ needs and experiences, global stakeholders should endorse bottom-up and systemic policy-making approaches towards sustainable people-centered health systems.
The findings of the thesis and the various global and national challenges that have emerged from case studies are crucial as the problems we have seen for tuberculosis in West Africa are not limited to this illness, and far outweigh the geographical context of developing countries.

Повний текст джерелаThe Internet of things (IoT) is a new technology that aims to connect billions of physical devices to the Internet. The components of IoT communicate and collaborate between each other in distributed and dynamic environments, which are facing several security challenges. In addition, the huge number of connected objects and the limitation of their resources make the security in IoT very difficult to achieve. In this thesis, we focus on the application of lightweight cryptographic approaches and blockchain technology to address security problems in IoT, namely : authentication and trust management. First, we were interested on some kind of IoT applications where we need to control remotely the execution of smart actuators using IoT devices. To solve this problem, we proposed an efficient and fine-grained access controlsolution, based on the Attribute Based Encryption (ABE) mechanism and oneway hash chains. Using formal security tools, we demonstrated the security of our scheme against malicious attacks. Second, we tackled the problem of authentication in IoT based fog computing environments. Existing authentication techniques do not consider latency constraints introduced in the context of fog computing architecture. In addition, some of them do not provide mutual authentication between devices and fog servers. To overcome these challenges, we proposed a novel, efficient and lightweight mutual authentication scheme based on blockchain technologyand secret sharing technique. We demonstrated the efficiency of our authentication scheme through extensive simulations. The third problem treated in this work is the trust management in IoT. Existing trust management protocols do not meet the new requirements introduced in IoT such as heterogeneity, mobility and scalability. To address these challenges, we proposed a new scalable trust management protocol based on consortium blockchain technology and fog computing paradigm, with mobility support. Our solution allows IoT devices to accurately assess and share trust recommendations about other devices in a scalable way without referring to any pre-trusted entity. We confirmed the efficiency of our proposal through theoretical analysis and extensive simulations. Finally, we showed that our protocol outperforms existing solutions especially in terms of scalability, mobility support, communication and computation

The adoption of a results-oriented governance in the public service has emerged as an organizational management approach as part o f a broad movement o f the new public management (NPM). In Brazil, public companies have been concerned in the search for better management contrai mechanisms to achieve good results in the delivery of public services for customers and users. The term 'Organizational Performance Management' refers to any integrated and systematic approach to improving performance to achieve strategic aims and pro mote the mission and values ofthe organization. Thus, this research studies practices related to the organizational performance management, enabling the targeting of efforts on improving key processes, taking into account the specific characteristics o f the public nature. Another relevant aspect o f this work comes from studies by Management Objectives and Managing for Results, adopting understanding Manage by Objectives to achieve the results. Thus, a literature search was performed to identify the main frameworks of organizational performance. After this stage, it was established a criticai analysis of frameworks by watching the main contributions and strengths. Finally, it was built an assessment model in arder to make a diagnosis of managerial processes and qualify at what stage the company, which is the object of this study, is focusing on the governance for results. The assessment result reflected the perceptions of employees and managers on performance and its determinants.
A adoção de uma governança voltada para resultados na administração pública surgiu como uma abordagem de gestão organizacional, fazendo parte de um amplo movimento da nova gestão pública (NGP). No Brasil, as empresas públicas têm se preocupado em buscar melhores mecanismos de controle da gestão no sentido de lograr bons resultados na prestação dos serviços públicos para os clientes e à sociedade usuária dos serviços. O termo 'Gestão de Desempenho Organizacional' refere-se a qualquer abordagem integrada e sistemática que vise melhorar o desempenho para alcançar objetivos estratégicos e promover a missão e os valores da organização. Assim, esta pesquisa estuda práticas relacionadas à gestão de desempenho organizacional, que possibilitem o direcionamento dos esforços na melhoria dos processos chaves, levando em consideração as particularidades inerentes à natureza pública. Outro aspecto de relevância deste trabalho advém dos estudos da Gestão por Objetivos e da Gestão para Resultados, adotando a compreensão de Gerenciar por Objetivos para se conquistar os Resultados. Deste modo, foi realizada uma pesquisa bibliográfica para identificar os principais frameworks sobre desempenho organizacional. Após esta etapa, foi estabelecida uma análise crítica dos frameworks, observando as principais contribuições e pontos fortes. E por último, foi construído um modelo de avaliação com o propósito de fazer um diagnóstico dos processos gerenciais, e qualificar em qual estágio a empresa objeto deste estudo se encontra, sob o enfoque da governança para resultados. O resultado desta avaliação refletiu as percepções dos funcionários e gestores sobre o desempenho e seus determinantes.

Повний текст джерелаThe healthcare systems are paying a great interest to the patients’ perspective for the organization of health care provision. Healthcare system which is accountable and responsive of patients’ needs and preferences is a major issue for the quality and efficiency of care. In this thesis, we analyze the views of patients for the supply of GP care in using different complementary methods about patients’ experience, satisfaction, importance or preferences. These methods are applied to a sample of patients in GP and to a sample of chronically ill patients in order to identify current and future major issues for the reorganization of GP care from the patients’ perspective. The results show the main role of the doctor-patient relationship and especially of the information exchange between doctor and patient and between patient and doctor. However the quality of the doctor-patient relationship is not enough. The technical quality of care (i.e. thoroughness) and the coordination are of high importance for patients. This work highlights that it is necessary to take into account the patients’ experiences in the analysis of their perspective (e.g. preferences) to fully and appropriately understand the results, especially in terms of willingness to change. The systematic and regular screening of patient preferences in daily GP practice can improve the doctor-patient communication and the content of the provision of care from the perspective of patients

Повний текст джерелаEste trabalho propõe analisar o fenômeno da terceirização desenvolvido ao longo das duas últimas décadas em Bio-Manguinhos. Trata-se de um estudo de caso realizado na unidade de produção de vacinas e reagentes para diagnóstico da Fundação Oswaldo Cruz. Inicialmente foi realizado um estudo de cenário, analisando a política de gestão do trabalho desenvolvida pelo Estado brasileiro para as instituições públicas. A seguir, a análise passou a verificar a inserção da Fiocruz nessas políticas, desde a sua criação e no decorrer de vigência de diferentes formas de contratação, alternando da extrema rigidez para a total flexibilidade sempre com foco na gestão do trabalho, e, como essas políticas se refletiram no desempenho de Bio-Manguinhos. Baseado no contexto da conformação do Estado e na análise do desempenho da unidade, o trabalho critica a falta de planejamento e de prospecção dessas políticas, que favoreça a inovação de processos, produtos e procedimentos e o desempenho pleno de uma unidade de produção de insumos para a saúde, tão necessários ao atendimento das necessidades da população brasileira. Critica também, a ausência de um modelo de Estado consolidado que sirva de arcabouço à formulação dessas políticas. Devido às fortes críticas dos órgãos de controle acerca da extrapolação dos limites da terceirização praticada nas últimas duas décadas e à falta de definição clara desses marcos legais, o trabalho apresenta uma metodologia baseada nas atribuições dos cargos do plano de carreiras da Fiocruz e culmina com a apresentação de uma matriz de atribuições passíveis de serem realizadas por contratação indireta. Conclui pela necessidade de convivência de dois quadros de trabalhadores: um permanente formado por servidores, estáveis e de carreira e outro flexível, executado por contratação indireta, de caráter eventual, temporário ou de apoio às atividades relacionadas à missão de Bio-Manguinhos. O trabalho ainda sugere a aplicação da mesma metodologia às demais unidades da Fiocruz e que a instituição afirme, frente aos órgãos de controle, quais atividades que ela precisa manter no quadro de servidores permanente e quais ela quer delegar a terceiros sem contudo, ferir a legislação vigente. Por fim, constata-se que a metodologia apresentada ameniza, mas não resolve o problema, dessa forma, recomenda-se à Fiocruz buscar mecanismos que altere o modelo de gestão pelo qual está submetida a fim de viabilizar as duas formas de incorporação de mão-de-obra.

With the proliferation of online multimedia content, the popularity of multimedia streaming technology, and the establishment of video coding standards, people can ubiquitously access and retrieve various multimedia contents via the Internet. However, with the current non-gauranteed QoS Internet infrastructure, compressed multimedia transport may suffer from insufficient bandwidth, packet loss, transmission delay due to network congestion, especially for an increasing number of users and increasing multimedia sizes. Such network errors may lead to serious video quality degradation annoying to human perception. Muticasting is consider an efficient solution to improving network utilization efficiency. However, heterogeneity in multicasting will make application-level error control over network even more complicated, thereby making it still an open problem. We will investigate technical issues on error resilience coding for MPEG-4 FGS-based video streaming in heterogeneous multicasting environment. In heterogeneous multicasting, there could be a large degree of heterogeneity on network bandwidth, transmission quality, type of codecs, and computing resources and display capability, etc. among client terminals. FGS video coding has the outstanding features of low complexity, supporting a wide range of user bandwidths rather than some specific bandwidths, and packet-loss resilience, which make it especially suitable for video streaming applications. Besides, in order to serve the lower bandwidth users, we provide two bit-rates bit-streams in the base layer. Clients can switch from high bit-rate to lower one, or else. However, switching directly will cause the drift error. Therefore, we propose a “switch bit-stream” to reduce the impact of drift. Combination of multicasting and switching scheme has better performance. Finally, we will establish a server/client prototype platform with one PC serving as the video sever and several others serving as the clients to demonstrate real-time video streaming services with our proposed approaches.
