No. of bitstreams: 0 / Este trabalho apresenta a contribuição obtida no desenvolvimento de um Gerador de Eletricidade Híbrido (HYBRIDGEN), com tecnologia nacional, focado nos sistemas de terceira geração de energia elétrica híbrido, composto por um módulo de células a combustível tipo PEMFC, associado a um acumulador chumbo ácido. Mostra-se também a sua capacidade de operar em modo contínuo, carga com demanda variável e fator de carga inferior a 50%. Foram abordados quatro temas principais. O primeiro refere-se a um estudo para a melhoria da eficácia na conversão de energia em corrente contínua (cc), ao regular o potencial de saída do conversor cc-cc. A energia é proveniente do módulo de célula a combustível de 1 kWe, equipado com sistema térmico de refrigeração e sistema de alimentação de gases, aqui denominados MCC1. Para tal, foi construído o modelo matemático do sistema conversor de corrente contínua (sistema conversor cc-cc), com solução suportada em equações diferenciais algébricas, ensaios no MCC1, bem como em simulação computacional no programa MATLAB7®. O segundo tema refere-se ao desenvolvimento do projeto e montagem do protótipo do HYBRIDGEN devido à inexistência no mercado brasileiro de um equipamento com as características necessárias tanto para a pesquisa, quanto para uso comercial. Desenvolveu-se uma placa controladora para o acumulador (PCC), os esquemas elétricos, os barramentos e o sistema de relés. Também foi utilizado o MCC1 em desenvolvimento pelo IPEN e ELECTROCELL® com tecnologia 100% nacional. O HYBRIDGEN foi instalado em um sistema móvel. O terceiro tema refere-se à análise de estabilidade do modelo matemático do sistema conversor cc-cc. Utilizou-se de quatro testes de estabilidade, sendo: 1 - pela Resposta em Frequência ao utilizar o Teorema do Mapeamento, de Nyquist; 2 - Lugar das Raízes, de Nyquist; 3 - função de teste Degrau, em pontos de operação e, 4 - função de teste Impulso, em pontos de operação. Por fim, apresentaram-se os resultados dos ensaios de potencial e corrente de uma célula a combustível unitária de 25 cm2, do MCC1, e do HYBRIDGEN. No desenvolvimento dos primeiros testes o MCC1 atingiu 704,55 We, (potência considerada condição predominante de operação). A seguir, demonstrou-se a capacidade do HYBRIDGEN para simultaneamente: alimentar cargas em corrente contínua; carregar o acumulador de 45 Ah; alimentar o inversor de 2 kWe e o autotransformador, para fornecer energia a equipamentos em 12Vcc, 127 Vac e 220Vac, 60 Hz, todos num total de 819,52 We. Esses resultados foram obtidos mesmo com limitações na refrigeração ventilada do MCC1, observadas no decorrer dos testes. Assim, o HYBRIDGEN se mostrou viável tecnicamente, e com grande potencial de uso. / Tese (Doutoramento) / IPEN/T / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP

A elaboração de Planos Tecnológicos (PT) pode representar um desafio significativo de esforço e planejamento para essas organizações. Os problemas mais comuns são falhas nas previsões dos projetos sejam eles de novos produtos, serviços ou processos. Esse estudo tem por objetivo desenvolver uma metodologia para identificar, classificar e quantificar os fatores denominados alavancadores e desafiadores que possam estar presentes na elaboração do PT. Desenvolveu-se um protocolo para entrevista e coleta de dados em duas fases, aplicado aos envolvidos na elaboração do PT. Na Fase 1 considerou-se a metodologia de construção do PT vigente na unidade de análise. Para Fase 2, considerou-se a metodologia T-Plan na construção do Mapa Tecnológico. Os fatores investigados foram organizados em dimensões (planejamento, desenvolvimento e aplicação) que foram segmentados em variáveis de pesquisa (viabilidade, compromissos, comunicação, direcionadores, priorização, monitoramento, aprendizado, revalidação, aplicação e replicação) e, dependendo dos resultados, eles foram classificados em alavancadores ou desafiadores. O processo de elaboração do PT foi também avaliado com base em dois atributos: qualidade e satisfação. Nas duas fases, ambos foram avaliados segundo a percepção dos entrevistados. Para a Qualidade, a representação foi em 4 quadrantes, para indicar a presença e a formalidade evidenciando a existência da variável da pesquisa. Para a Satisfação foram avaliados estatisticamente considerando o valor médio e desvio padrão entre a condição atual e a desejada. Essa distancia caracterizou as oportunidades das mudanças. A unidade de análise foi o Centro de Célula a Combustível de Hidrogênio - CCCH, um departamento do Instituto de Pesquisa Energéticas e Nucleares do Brasil. A análise da Fase 1 considerou um PT elaborado anteriormente e da Fase 2 foi aplicado a metodologia T-Plan. Nessa segunda fase foi construído o Mapa Tecnológico para os próximos dez anos considerando direcionadores estratégicos, produtos, tecnologias e recursos necessários para realização do protótipo comercial até 2024 e assim viabilizar a inclusão da Célula a Combustível na Matriz Energética Nacional. Com as análises dos resultados das duas fases verificou-se: Fase 1: foram identificados como fatores Desafiadores: Direcionadores e Aplicação; como Fatores Potencial Desafiador: Viabilidade, Priorização, Monitoramento, Aprendizado e Revalidação; como fatores Potencial Alavancador: Replicação e como fatores Alavancadores: Compromisso e Comunicação. Fase 2: todos fatores foram classificados como Alavancadores: Viabilidade, Compromisso, Comunicação, Direcionadores, Priorização, Monitoramento, Aprendizado, Revalidação, Aplicação e Replicação. Concluiu-se que na metodologia T-Plan há uma sensível alteração da avaliação dos fatores Alavancadores e Desafiadores. O Mapa de Rotas Tecnológicas do CCCH, construído na Fase 2 indicou as seguintes rotas tecnológicas: 1) preparação de materiais e principais componentes do módulo; 2) partir da demanda do mercado para chegar aos novos produtos; 3) partir do desenvolvimento das tecnologias para chegar aos novos produtos; 4) desenvolvimento dos materiais para chegar aos produtos e atender aos drivers. Tais resultados sugerem concluir que a aplicação da metodologia do T-Plan não é só viável, mas até recomendável, no âmbito da elaboração de Planos Tecnológicos das Instituições de Pesquisa Pública. / Dissertação (Mestrado em Tecnologia Nuclear) / IPEN/D / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP

Este trabalho apresenta resultados de estudos e caracterizações de Conjuntos Eletrodo/Membrana (MEAs) de Células a Combustível a Membrana Polimérica (PEMFC). Algumas condições de operação de células e diferentes processos de produção de MEA foram investigados. A técnica de Espectroscopia de Impedância Eletroquímica (EIE) (em situ - 0 a 16 A) foi usada \"on-line\" como uma ferramenta de diagnóstico, relativa ao desempenho de célula. As medidas de EIE foram feitas através do Sistema de EIE para células a combustível FC350 (GAMRY), junto a um PC4 Potentiostato/Galvanostato e conectado à carga dinâmica (TDI) para experimentos de EIE \"on-line\" (100 mHz - 10 kHz, dU = 5 mV). MEAs com 25 cm2 de área ativa, usando eletrocatalisadores PtM/C 20 % (M = Ru, Sn ou Ni) fabricados usando o Método de Redução por Álcool (MRA). A tinta catalítica foi diretamente aplicada no Tecido de Carbono (GDL) e este prensado na membrana de Nafion® (105). MEAs usando eletrocatalisadores Pt/C e PtRu/C 20 % da E-TEK foram fabricados para comparação. Todos os cátodos foram confeccionados com Pt/C 20% da E-TEK. Foram fixadas as concentrações de metal nobre em 0,4 mg Pt.cm-2 no anodo e 0,6 mg Pt.cm-2 no catodo (E-TEK). Diagramas de Nyquist dos MEAs com Pt/C e PtRu/C da E-TEK ou PtM/C MRA apresentaram as mesmas resistências de ôhmicas para os MEAs. Este fato pode ser explicado por supressão de aglomerados durante o processo de preparação do MEA ou pela homogeneidade do eletrocatalisador ancorado ao carbono. Também pôde ser observado, a baixas densidades atuais que há uma diferença de desempenho significante entre o eletrocatalisadores da ETEK e os preparados pelo MRA. Os resultados das curvas de polarização confirmaram que PtM/C MRA apresentara um aumento de atividade para as células alimentadas com metanol e etanol. A técnica de EIE se mostrou eficiente para a avaliação do método de preparação dos MEAs e do desempenho da célula, os resultados de EIE mostraram uma coerência na escolha do modelo do circuito elétrico para os MEAs utilizando hidrogênio, metanol e etanol. Esta coerência indica que outras resistências não consideradas no modelo não são relevantes na resistência total dos MEAs. / This work reports results of studies and characterization on Membrane Electrode Assemblies (MEAs) for Proton Exchange Membrane Fuel Cell (PEMFC). Some cell operation conditions and different processes of MEA production were investigated. The Electrochemical Impedance Spectroscopy Technique (EIS) (in situ - 0 to 16 A) was used \"on-line\" as a tool for diagnosis, concerning the cell performance. The EIS measurements were carried out with a FC350 Fuel Cell EIS System (GAMRY), coupled to a PC4 Potentiostat/Galvanostat and connected to the electronic load (TDI) for \"on-line\" EIS experiments (100 mHz - 10 kHz, dU = 5 mV). MEAs with 25 cm2 surface area, using PtM/C 20% (M = Ru, Sn or Ni) electrocatalysts were manufactured using the Alcohol Reduction Process (ARP). The catalytic ink was applied directly into the Carbon Cloth (GDL) and pressed in the NafionR membrane (105). MEAs using Pt/C and PtRu/C 20% from E-TEK electrocatalysts were manufactured by comparison. All the cathodes were sprayed with Pt/C 20% from E-TEK. The noble metal concentrations used were set to 0.4 mg Pt.cm-2 at the anode and 0.6 mg Pt.cm-2 at the cathode (E-TEK). Nyquist diagrams of the MEAs with Pt/C and PtRu/C from E-TEK or PtM/C (M = Ru, Sn or Ni) ARP showed essentially the same ohmic resistances for the MEAs. This fact can be explained by suppression of agglomerates during the MEA preparation process or by the homogeneity of the anchored electrocatalysts at the carbon surface. It could also be observed, at low current densities, that there was a significant performance difference between the electrocatalysts from E-TEK and those prepared with the Alcohol Reduction Process. The polarization curves results confirmed that the PtM/C (M = Ru, Sn or Ni) ARP showed an activity increase for the methanol and ethanol fed cells. The technique of EIE was shown efficient for the evaluation of the method preparation of MEAs and the acting of the cell, the results of EIE showed coherence in the choice of the model the electric circuit for MEAs using hydrogen, methanol and ethanol. This coherence indicates that other resistances no considered in the model are not relevant in the total resistance of MEAs.

Over the past few years and up to date, many companies around the globe have implemented Enterprise Resource Planning (ERP) systems. Implementing ERP system in an organisation is considered as an irresistible challenge, with the typical ERP system implementation approach. In correspondent, management in an organisation are facing critical challenges' to make decision on a specific ERP system implementation strategy, however, any considered decision would influence development, testing and ultimately the success of the implementation. Therefore, this thesis aims to examine solution to how organisation can decide or choose the best ERP system implementation strategy and explore the one that could be highly recommended by considering enterprise and consultant perspectives.   In order to accomplish the purpose of this thesis, qualitative and quantitative method of collecting and analysing data were adopted. Quantitative and qualitative data were collected through the mean of questionnaire and structure interview. This is one of the reasons why this thesis can be viewed in an inductive and deductive approaches. To this end, exploratory and descriptive knowledge should be derived from this study. Analysis of this thesis has discovered that, there are many influencing factors in which organisation needed to be considered when making choice of a particular ERP system implementation strategy. These factors include: (i) Size and Complexity of an organisation (ii) Degree of internationalisation (iii) Number of requirements (iv) Nature of integration and (v) Skills and Experience of people within an organisation. In order to choose appropriate strategy for ERP system implementation, organisation should considered to implement a skeleton system in which other application can be added to the systems when it is in operation. Clarification of a business vision that would call for the legacy system replacement or re-modification, is also essential for an organisation to consider. Considering the above statements, organisation should be able to choose appropriate strategy that would fit their business processes. Nevertheless, Phased strategy is considered as the best or appropriate implementation strategy in which organisation can rely upon. Exploring Phased strategy simply means that, the problem of making choice of a particular implementation strategy will be minimal. That is; organisations that are willing to implement ERP system can easily consider phased strategy as their best alternative in order to attain success implementation.

La présente thèse a pour objet d’identifier le préjudice financier par la distinction entre le dommage et le préjudice et de prévoir des règles d’indemnisation adaptées au fonctionnement des marchés financiers. Le préjudice financier a été défini comme celui qui résulte de la variation d’une valeur ou du cours d’un titre financier. Il ressort de cette définition que le préjudice financier « pur » doit être distingué d’autres types de préjudices et notamment de la perte de chance. Cette distinction s’impose parce que ces deux types préjudices ne sont pas indemnisés de la même manière. Il était donc primordial de souligner l’inadéquation de l’application systématique de la notion de perte de chance en matière financière. En effet, dans ses dernières décisions la Cour de cassation applique constamment la perte de chance. Cependant, cette jurisprudence amène à une limitation de l’indemnisation, car la perte de chance est indemnisée en fonction de la chance d’éviter le préjudice final et elle ne correspond jamais à la totalité du préjudice subi. Afin d’indemniser intégralement le préjudice de l’investisseur, il fallait essayer de démontrer que l’incertitude concernant le comportement de la victime en l’absence de la faute peut être levée en matière financière. Or, en principe, l’interposition de la décision de la victime entre la faute et le préjudice modifie les rapports de causalité. Toutefois, si on prend en compte l’impact de la faute sur le cours d’un titre, il sera possible d’établir le lien causal entre la prise de la décision d’investissement et la faute. Tel est notamment le cas lorsque la décision d’investissement est prise après une manipulation de marché. La perte de chance ne permet pas de prendre en compte la variation du cours causée par l’acte dommageable. Or, cette spécificité doit être prise en compte non seulement pour identifier le préjudice financier et mais aussi pour l’évaluer. L’identification du préjudice est possible par le recours à la distinction entre le dommage et le préjudice. Cette démarche permet d’établir le lien de causalité plus facilement. En effet, le préjudice a été analysé comme l’aboutissement d’un processus dommageable dans lequel il y a plusieurs événements qui interviennent. Dans la chaîne des événements, le préjudice financier apparaît comme une suite du dommage, lui-même causé par la faute. Ces éléments, à savoir la faute, le dommage et le préjudice, se relient entre eux par des liens causals. Or, s’il s’avère particulièrement difficile de prouver le lien de causalité entre la faute et le préjudice directement et notamment lorsque la décision d’investissement s’interpose entre la faute et le préjudice lui-même, il sera possible d’établir deux liens de causalité : le premier qui relie la faute au dommage et le deuxième qui relie le dommage au préjudice. Enfin, nous avons constaté que l’absence de règles spéciales en matière d’indemnisation et l’efficacité réduite des règles existantes nécessitent l’introduction des règles spécifiques adaptées au contexte financier. Deux séries de mesures ont été proposées afin d’améliorer le système existant. En premier lieu, on peut accroître l’efficacité du système par l’introduction de règles de procédure adaptées au contexte financier. En deuxième lieu, on peut prévoir un régime spécifique applicable au fond. S’agissant des règles de procédure, la présente étude a examiné plusieurs solutions possibles : la création d’in tribunal des marchés financiers, l’extension de l’action de groupe aux abus de marché, amélioration des modes alternatifs de règlement des conflits et la création de fonds d’indemnisation. S’agissant des règles de fond, le droit financier peut se doter d’un régime spécial de responsabilité afin d’assurer une meilleure lisibilité du droit français. / -This thesis aims to identify and solve some significant problems related to investor’s financial harm. The thesis proposes a method to establish the proof of the financial harm and discusses various measures of calculating damages. The thesis begins with a definition of the term financial harm and therefore attempts to identify the financial loss resulting from some harmful activities. The context in which the investor is harmed involves the distinction between “damnum”, i.e. the origin of the harm and its consequence, the “praejudicium “. The introduction of the distinction permits a new method for reliance’s proof between harmful activity and financial loss. In particular the distinction permits to observe that the proof of the loss is different when the investor’s decision is made but for the harmful activity and when the harmful activity intervenes after the investor’s decision. Therefore, proof of the loss and evaluation of damages are established in accordance with the origin of the harm. The thesis examines a possible change to the rules of causation and loss evaluation in order to improve investor’s compensation. In an attempt to remedy the gaps perceived in law Part II discusses the adoption of appropriate compensation schemes.

Teachers’ beliefs are central to determining children’s optimal educational experiences. However, some studies related to teachers’ beliefs yielded findings that rendered beliefs and practices incongruous. Although the principles of developmentally appropriate practices that synthesize theoretical and empirical research on child development have been adapted to various contexts other than its original United States of America (USA) context, developmentally appropriate practices remain contentious as to its relevance in these contexts. What is appropriate for children’s education seems debatable, largely determined by social expectations of childhood and children. Cultural diversity seems to be the new dispensation in this discourse. Fundamentally, research on preschool teachers’ beliefs about developmentally appropriate educational practices, adds to literature about cultural context variables in preschool provision from different contexts. Purpose: This study examined how teachers’ practical experiences framed their beliefs and understanding of children’s educational experiences within a developmentally appropriate framework and a bioecological systems theory. Paradigm/Design/Methods: A constructivist paradigm within the qualitative approach guided this study. Video and photographs became the basis to elicit teachers’ beliefs about children’s educational experiences. Children’s educational experiences were analysed along five constructs related to the concept of DAP; teaching strategy, use of materials, scheduling of children’s learning, assessment, and consideration of children’s individuality. Findings: Teachers’ beliefs corroborated the DAP framework, but their practices that were more teacher-directed, contrasted the DAP principles. They used formally structured teaching approaches, as materials in three-out-of-four classes observed remained ‘silenced’. The schedules were formally structured, subject-based, with limited flexibility, as assessment for children’s learning focused on limited aspects of the cognitive domain. Conclusion: Teachers’ beliefs seemed to support educational practices that embrace the principles of DAP. However, some context-related factors, which include pressure from parents, competitive school environments, preparation for the interview, different transition requirements, peer pressure, and perceived lack of time limited their use of DAP. I extrapolate these factors to the bioecological systems theory, to understand the dynamics of early childhood education provision in Kenya. Practical implications/Originality/Value: This study adds to literature on teachers’ beliefs about children’s educational experiences from a developing country context, as well as adding to studies that have used visually elicited interviews. It also provides the details of children’s educational experiences, in part, to appreciate the current conversation on the status and the nature of focus on standards or skills-based dynamics in preschool provision. Besides, it might be the first study in Kenya to embrace the DAP framework and the bioecological systems theory. The seesaw model advanced in this study synthesizes the originality of the study by conceptualizing the theoretical as well as empirical literature on developmentally appropriate educational practices, as a valuable framework to understand and interpret competing priorities that might affect preschool provision. The seesaw model is also valuable in locating and extending the conversation about different stakeholders’ priorities, not only in Kenya, but also in other societies. / Thesis (PhD)--University of Pretoria, 2010. / Educational Psychology / unrestricted

South Africa is a heterogeneous society. It is a multilingual, multicultural country with more than eleven official languages. It is a country that also has big educational and economic inequalities. These differences are pertinent barriers that often obstruct communication, also and especially in health communication. This study addresses such a problem, by first exploring the effectiveness and/or appropriateness of existing schizophrenia information material The Alliance Programme which was produced in the USA for universal consumption and is currently used in the South African context. In the study the externally produced schizophrenia information material is adapted to fulfil in the specific needs and preferences of the audience targeted in this study. The study was conducted based on the assumption that people need to access information that is relevant, easy to understand and appropriate to them in order to make informed decisions about their health. This study was conducted at the Weskoppies hospital in Pretoria (South Africa) among Tshwana-speaking patients suffering from schizophrenia. The specific aim of this study was to communicate the information in such a way that this group could use it optimally. Since this empirical study’s main aim was to evaluate and adapt the Alliance Programme to make it more suitable for the South African context, a formative research design was implemented. Usability testing was chosen as the research method. Literature review, individual semi-structured interviews, focus group interviews and participant observation were employed as data collection methods. The data was analysed by means of qualitative content analysis. The findings of this study indicated that the adapted messages or information about schizophrenia did improve the patients’ reception of the information. It was then concluded in this study that messages or information should either be adapted or created to suit the needs of a specific audience. This study also recommended that in order to make sure information (about schizophrenia) is communicated effectively and/or appropriately to any group (of patients suffering from schizophrenia), a participatory communication design should be used. / Dissertation (MIS)--University of Pretoria, 2009. / Information Science / unrestricted

Advances in neonatology have led to increased numbers of high-risk neonates surviving and intensified interest in the developmental outcomes of this population. In the South African context prematurity and low birth weight are the most common causes of death in the perinatal period and the same risk factors that contribute to infant mortality also contribute to the surviving infants’ increased risk for developmental delays. As a result of the interacting biological and environmental risk factors of prematurity, low birth weight, poverty and HIV and AIDS in the South African context Kangaroo Mother Care (KMC) has been developed as best practice to promote infant survival and to facilitate mother-infant attachment. Mother-infant attachment may lead to synchronous interaction patterns between the mother and infant which forms the basis of early communication development. Early communication intervention (ECI) services are recommended as early as possible as high-risk infants are especially at risk for feeding difficulties and communication developmental delays. It is, however, not clear what the content of an ECI programme should be and how it should be implemented according to the changing communication and feeding developmental needs of the infant while receiving KMC. There appears to be a dearth of research on the earliest stages of communication development in high-risk neonates, which should form the foundation of such a programme. A descriptive survey was conducted to describe the development of 25 high-risk infants and their mothers’ changing needs from admission to discharge from a KMC unit. Each participant and mother dyad was followed up over an average of 11 days of data collection with three to four data collection sessions. Data was collected by means of direct observation during routine care-giving activities. The different developmental subsystems of the participants’ feeding, communication, neuro-behavioural organization and mother-neonate interaction were described. The results demonstrated that subtle, but definite changes could be observed in the participants’ development. Development in all the different areas occurred over time as the participants progressed through the three developmental states of the in-turned state, coming-out state and reciprocity state. As the participants progressed during the 11 days of data collection and were increasingly able to attend to their environment, they also developed the ability to regulate and organize their own behaviour in order to develop more complex communication, feeding and interaction skills with their mothers. The functioning of the participants’ sensory systems developed in a specific order namely tactile, auditory and then visual. Although the participants developed consistently throughout their stay in the KMC unit, mother-neonate interaction never reached optimal levels. The importance of an individualized training programme for each mother is reflected in the finding that the neonate’s developmental level and progress needs to be considered when implementing the ECI programme. The need for speech-language therapy involvement in KMC is emphasized in the light of a shortage of practicing speech-language therapists in South Africa. It is therefore imperative that the prevention of communication delays and feeding difficulties in high-risk neonates as well as parent training assume priority. / Dissertation (MCommunication Pathology)--University of Pretoria, 2008. / Speech-Language Pathology and Audiology / unrestricted

Identifying factors associated with appropriate and inappropriate therapies in patients with implantable cardioverter-defibrillator (ICD) could help to identify those at risk and reduce the incidence of this emergency situation which has detrimental effect on mortality and morbidity in patients with ICD. These studies were designed to find the prevalence and factors associated with appropriate and inappropriate therapies in patients with ICD.

An increasingly number of people are using the internet in Sweden, but many of the elderly still do not use the internet. At the same time, the global population is aging. To counteract the digital exclusion that exists for the elderly, the purpose of this study is to find out how a website should be made more user-friendly for senior Internet users. This by focusing on text formats, fonts, and colors that seniors prefer to have on websites to increase the readability. To find out, a literature study has been done together with a questionnaire and an interview study. From this, a result is presented that shows which adaptations that are good to make to people where functions such as sight, hearing, memory, and coordination have deteriorated. The result mainly shows that there must be high contrasts between text and background, larger text is preferred that is not italicized or only consists of capital letters and that there should not be much text on a front page.
