Full textAbstract:
As incubadoras universitárias têm se constituído nas principais universidades brasileiras desde o fim da década de 1990. Elas trabalham dentro da linha de economia solidária, no desenvolvimento de cooperativas populares ou empreendimentos econômicos solidários e, durante esse trabalho, enfrentam diversos desafios. Um deles é conseguir contribuir com tais empreendimentos em suas dimensões empresa - uma gestão atenta à qualidade do produto ou serviço, aos processos e operações para sua maior eficiência, à sua inserção no mercado e à melhor organização dos seus recursos financeiros e não-financeiros; e associativa - uma gestão atenta à importância de sua missão social, à manutenção de sua vitalidade associativa, aos processos para que a democracia prevaleça e ao seu enraizamento na comunidade e no seu setor de atuação de forma cooperativa. Este trabalho avaliou o desenvolvimento de uma incubadora recém-formada, nos seus dois anos iniciais, na USP campus Ribeirão Preto, com a análise voltada para sua estrutura, equipe, metodologia e atuação junto aos empreendimentos incubados, percebendo as condições favorecedoras e desafiadoras de uma incubação que de fato contribua com ambas as dimensões. O método utilizado foi o de sistematização de experiências, considerado apropriado para construir a linha do tempo da incubadora, constituir os principais marcos e eixos do trabalho realizado e promover a reflexão crítica dos fatos e experiências levantados. Os resultados indicam que houve dificuldade na integração entre as dimensões empresa e associativa na atuação junto aos grupos incubados, com destaque ou maior ênfase para uma dimensão ou outra ao longo do tempo, devido principalmente aos acúmulos da equipe com maior participação naquele momento. Além disso, a percepção dos membros da incubadora foi avaliada por meio de entrevistas estruturadas, e indicou que alguns creditam tal enfoque em uma dimensão ou na outra por conta das demandas do grupo naquele momento, outros para qual fosse a constituição e formação da equipe mais próxima do trabalho e ainda porque indivíduos específicos de cada grupo pudessem demandar abordagens distintas. Por fim, concluiu-se que a incubadora produziu efeitos positivos e negativos devido a essa dificuldade no equilíbrio entre ambas as dimensões nos trabalhos realizados e que, com essa informação, as incubadoras universitárias pelo país podem buscar maior integração entre elas e, assim, atingir através de seus trabalhos com os empreendimentos solidários maior eficiência econômica e felicidade humana.The university incubators have been constituted in the main Brazilian universities since the end of the 1990s. They work within the solidarity economy line, in the development of popular cooperatives and solidarity economy enterprises, and during this work, face several challenges. One of them is their capability to achieve contributions to the solidarity enteprises in their company dimension - a careful management to product quality or service, processes and operations to their greater efficiency, its insertion in the market and the best organization of its financial and non-financial resources; and their associative dimension - a management attentive to the importance of its social mission, the maintenance of its associative vitality, processes that makes democracy prevails and its rootedness in the community and its industry, in a cooperative manner. This study evaluated the development of a newly formed incubator in its first two years, at USP campus Ribeirao Preto, with focused analysis of its structure, staff, methodology and performance with the incubated enterprises, realizing that favor and challenging conditions of an incubation that actually contribute to both dimensions. The method used was the systematization of experiences, considered appropriate to construct the time line of the incubator, constitute major milestones and axes of the work and promote critical reflection of the facts and experiences raised. The results indicate that there were difficulties in integration between the company and associative dimensions in performance with the incubated groups, highlighting or with greater emphasis on one dimension or another over time, mainly due to the accumulations of the team with greater participation at that time. Moreover, the perception of the members of the incubator was evaluated through structured interviews, and indicated that some credited an approach focused in one dimension or the other because of the demands of the group at that time, others for which was the establishment and training of staff nearest to the work and because specific individuals of each group might require different approaches. Finally, it was concluded that the incubator has had positive and negative effects due to the difficulty in balancing both dimensions in the performed work, and with this information, the university incubators around the country may seek greater integration between them and thus achieve, through their work with solidarity enterprises, greater economic efficiency and human happiness.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIORA partir de pressupostos teóricos da argumentação (Shiffrin, 1987; Wegman, 1994; Gryner, 2000; Gille, 2001) aliados a estudos que tratam de falas opinativas (Shiffrin 1990; Shi-xu, 2000) e a trabalhos realizados no âmbito da avaliação (Labov, 1972; Linde, 1997; Martin, 1999, 2003), este estudo investiga a dimensão avaliativa da argumentação na fala opinativa de profissionais de uma empresa em processo de mudança. A metodologia de estudo compreende a análise das entrevistas apresentadas por quatro empregados da empresa, acerca de como avaliam a atuação do grupo gestor da organização e de como vêem as suas próprias possibilidades de atuação neste contexto. A análise dos dados permitiu a emergência de padrões que identificam a avaliação como um movimento argumentativo, bem como desvendou marcas avaliativas que incidem pervasivamente na estrutura da argumentação do discurso de opinião dos informantes desta pesquisa. Os resultados também mostram que a avaliação pode marcar a opinião pela modificação dos papéis de autor e animador (Goffman, [1979] 2002, 1981), além de poder ser formatada na sustentação através de silogismo inferencial a partir de narrativas factivas, hipotéticas ou fictivas (Oliveira, Bastos e Pereira, 2007).
From theoretical budgets on argumentation (Shiffrin, 1987; Wegman, 1994; Gryner, 2000; Gille, 2001) allied to studies which deal with opinative speeches (Shiffrin 1990; Shi-xu, 2000) and researches developed in the scope of evaluation (Labov, 1972; Linde, 1997; Martin, 1999, 2003), this study looks into the evaluative dimension of argumentation in opinative speech by professionals at a company in process of change. The study methodology takes into account the analysis of interviews given by four employees of the company towards their evaluation of the organization administrative group and of their own possibilities to act in this context. The data analysis found out the appearance of standards that identify the evaluation as an argumentative move, and unveiled as well the evaluative marks that pervasively occur in the argumentation structure of the opinion discourse by the informers of this research. The results also show that evaluation may assign opinion by the exchange of author and animator roles (Goffman, [1979] 2002, 1981), besides the possibility of being shaped in sustaining through inferential syllogism based on factual, hypothetical or fictive narratives (Oliveira, Bastos e Pereira, 2007).

Full textAbstract:
Personality and brand factors were examined to determine if consumers of certain personality dimensions would be more favorable toward specific brand factors of three major sports media companies: Sports Illustrated, ESPN, and Fox Sports News. College-age sports news followers were tested to ascertain personality, brand evaluation, and media usage. Findings disclosed associations of personality dimension and brand preference, for example, “Agreeable” participants favored ESPN branding. Participants scoring low on “Extroversion” favored the Sports Illustrated brand. Other findings included an association between “Agreeableness” and TV; and frequent digital media users favored ESPN. Findings have implications for integrating personality research in marketing strategies that target college-age consumers.

Full textAbstract:
This thesis is an investigation of the subject of extra dimensions in particle physics. In recent years, there has been a large interest in this subject. In particular, a number of models have been suggested that provide solutions to some of the problem with the current Standard Model of particle physics. These models typically give rise to experimental signatures around the TeV energy scale, which means that they could be tested in the next generation of high-energy experiments, such as the LHC. Among the most important of these models are the universal extra dimensions model, the large extra dimensions model by Arkani-Hamed, Dimopolous, and Dvali, and models where right-handed neutrinos propagate in the extra dimensions. In the thesis, we study phenomenological aspects of these models, or simple modifications of them. In particular, we focus on Kaluza–Klein dark matter in universal extra dimensions models, different aspects of neutrino physics in higher dimensions, and collider phenomenology of extra dimensions. In addition, we consider consequences of the enhanced renormalization group running of physical parameters in higher-dimensional models.QC 20120427

Full textAbstract:
Corporate Social Responsibility, or CSR, is a subject whereby enterprises execute their business with respect and responsibility towards the natural and the social environment, their own and their subcontractor’s labor and towards others whom it may concern. CSR is a phenomenon that is rapidly spreading and every day yet more enterprises and companies are joining the concept. One could claim that by performing CSR related work within the own enterprise the company’s brand could be improved and the consumers more satisfied, which in turn is good for business, and there are yet more long term reasons for an enterprise to perform CSR. For enterprises within the manufacturing industry or a service enterprise the CSR related work is more straightforward than the CSR performed within a public equity company, where CSR is translated into a more complex strategy. Ratos is a public equity company with headquarters in central Stockholm, Sweden. They have a great many holdings where the participation share is 60% or above. In some cases the participation share is 100%. How CSR is implemented in a company like Ratos is not clear, and therefore it is interesting to see how this type of work is performed within this company. Some even consider every single holding to be responsible for their own CSR strategy, and not a part of the investor's responsibility. Therefore CSR could be considered to be a less important subject for public equity companies. It’s a general belief that public equity companies don’t care much about how their holdings are doing business as long as they meet the goals for annual return on invested money. The purpose of this study is map out the CSR related work performed both within the public equity company Ratos, and the impact this have on their holdings CSR strategy. This mapping will be done by comparing the definition of CSR and the five dimensions this definitions holds against the collected data. This includes the economical responsibility, the responsibility towards the natural and the social environment, the stakeholder responsibility and the voluntary work performed. By comparing the five dimensions Dahlsrud, A. (2008) defines and the CSR initiatives by Ratos it could be proved that Ratos is executing a wide range CSR strategy. It could also be established that the CSR related work performed within Ratos is well documented, substantial and influenced by continuous improvement.CSR, Corporate social responsibility är ett begrepp som relateras till hur företag ska jobba med respekt och ta hänsyn till sina arbetare, miljön samt samhället de jobbar i. CSR är ett fenomen som sprider sig snabbt just nu och fler företag hoppar på trenden. Genom att jobba med CSR kan det argumenteras att kunder blir mer nöjda och företaget kan bygga en bättre image för företaget. Det finns många anledningar för företag att jobba mer med CSR vilket gynnar kunden men också företaget i det långa loppet. För företag som producerar varor eller säljer tjänster kan det vara lättare att jobba med CSR än för företag som endast investerar i andra företag. För investerings bolagen kan CSR vara ett mer komplicerat verktyg. Ratos är ett investeringsbolag med säte i Stockholm, Sverige. De har flertal innehav där det har en stor del av ägarskapet. Ratos äger ofta mer än 60 % i flera företag och 100 % i ett antal. Det som är intressant i ett investerings bolag som Ratos är hur de arbetar med CSR. Det är inte lika tydligt som hos andra företag. Det kan också anses vara mindre viktigt för företaget då investerings bolagen inte ses som den skyldige i många lägen, det ska vara innehavets ansvar att se till att jobba med CSR perspektiven. Det är också en generell uppfattning att investeringsbolagen inte bryr sig hur deras innehav arbetar så länge den önskade avkastningen möts. Syftet med detta projekt är att kartlägga arbetet som Ratos gör ur ett CSR perspektiv, både inom Ratos men också hur de influerar sina innehav och vad som krävdes ur ett CSR perspektiv från sina innehav. Denna kartläggning kommer att göras genom att jämföra definitionen av CSR ur fem dimensioner mot empiri. Här inkluderas det ekonomiska, miljö, intressenternas, sociala och volontär perspektivet. Jämförandet mellan de fem dimensionerna som Dahlsrud definierar och det arbete som Ratos gör visade att ett investeringsbolag kan arbete ur ett brett CSR perspektiv. Det kan också konstateras att det arbete som görs på Ratos är väl dokumenterat, påtagligt samt ständigt under utveckling. Fallstudien baseras på intervjuer, artiklar, hemsidor samt teori böcker.

Full textAbstract:
This thesis presents the development of ultrafast near-infrared (NIR) waveguide laser sources, through the fabrication of waveguides in Yb-doped bismuthate glass using ultrafast laser inscription (ULI). An integrated linear cavity waveguide laser is demonstrated in the glass with output powers of 163 mW and a slope efficiency of 79%. The laser performance is comparable to bulk systems while providing additional advantages in terms of low threshold ~35 mW and system compactness. The simultaneous achievement of low propagation losses and preservation of the fluorescence properties of Yb ions after the ULI process is key to the outstanding laser performance. Based on the current interest in ultrafast laser development using graphene as a saturable absorber (SA), a systematic study of nonlinear absorption in graphene is presented. The nonlinear optical characterisation of graphene at the wavelengths of 1 μm and 2 μm contributes to the experimental evidence for the wavelength independent absorption saturation in the material. Ultrashort pulse generation from the Yb-doped bismuthate waveguide laser is investigated using SAs based on semiconductor technology and carbon nanostructures. The quasi-monolithic waveguide laser, employing a graphene SA generated ~485 mW output power with a slope efficiency of 49%. The laser generated ~1 ps pulses in a Q-switched mode-locked regime, with the mode-locked pulses measuring a high repetition rate of 1.5 GHz. Ultrafast laser development is also investigated based on a novel evanescent-wave mode-locker device, fabricated by ULI. The device consists of an orthogonal waveguide with the right-angle positioned along its angled facet. The substrate is converted into a mode-locker by depositing carbon nanotube SA at the angled facet. Mode-locked operation is demonstrated by incorporating the substrate in an Er-doped ring laser, generating ~800 fs pulses at 26 MHz. Some preliminary work is done to replicate the device design in an active gain medium, namely, Yb-doped bismuthate glass, for the development of compact laser sources.

Full textAbstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorO caos determinístico é um dos aspectos mais interessantes no que diz respeito à teoria moderna dos sistemas dinâmicos, e está intrinsecamente associado a pequenas variações nas condições iniciais de um dado modelo. Neste trabalho, é feito um estudo acerca do comportamento caótico em dois casos específicos. Primeiramente, estudam-se modelos préinflacionários não-compactos de Friedmann-Robertson-Walker com campo escalar minimamente acoplado e, em seguida, modelos anisotrópicos de Bianchi IX. Em ambos os casos, o componente material é um fluido perfeito. Tais modelos possuem constante cosmológica e podem ser estudados através de uma descrição unificada, a partir de transformações de variáveis convenientes. Estes sistemas possuem estruturas similares no espaço de fases, denominadas centros-sela, que fazem com que as soluções estejam contidas em hipersuperfícies cuja topologia é cilíndrica. Estas estruturas dominam a relação entre colapso e escape para a inflação, que podem ser tratadas como bacias cuja fronteira pode ser fractal, e que podem ser associadas a uma estrutura denominada repulsor estranho. Utilizando o método de contagem de caixas, são calculadas as dimensões características das fronteiras nos modelos, o que envolve técnicas e algoritmos de computação numérica, e tal método permite estudar o escape caótico para a inflação.
Deterministic chaos is the most interesting aspect with regard to the modern theory of dynamical systems, and is intrinsically associated with small changes in initial conditions of a given model. This paper is a study about the chaotic behavior in two specific cases. First, we study non compact pre-inflationary FRW models with a minimally coupled scalar field, and then anisotropic models of Bianchi IX. In both cases the material component is a perfect fluid. Such models have a cosmological constant and can be studied via a unified description using suitable transformations of variables. These systems have similar structures in phase space, called saddle-centers, which make the solutions to be contained in hypersurfaces whose topology is cylindrical. These structures dominate the relationship between collapse and escape to inflation, which can be treated as basins whose boundary can be fractal, and can be associated with a structure called a strange repeller. Using the boxcounting method, which involves methods and algorithms for numerical computation, we calculate the characteristic dimension of their sets. This method allows to study the chaotic escape to inflation.

Mestrado em Economiae e Gestão de Ciência e TecnologiaA evolução da indústria farmacêutica nas últimas décadas, embora integrando-se no quadro de desenvolvimento global da economia, preserva a sua própria autonomia, devido ao carácter eminentemente social, traduzível nos seus objectivos de combate à doença e à morte, bem como de busca progressiva do bem estar físico e psíquico da humanidade. E porque nesse domínio, nada é imutável, o grau crescente de exigência quanto a níveis de qualidade, de eficácia e de segurança no sector implica uma postura dinâmica e criativa do lado da oferta. Neste contexto, a I&D e a Inovação têm sido importantes motores da indústria farmacêutica, processos em que a dimensão imaterial predomina, influenciando o comportamento dos demais factores das actividades inovadoras. Assim, este estudo tem como âmbito a indústria farmacêutica, num contexto de globalização económica, com incidência nos vectores de l&D e de Inovação e como objectivo responder fundamentalmente a duas questões: i) Num sector em que a Inovação e a l&D são essenciais, como é o caso da indústria farmacêutica, saber qual a influência da procura, e designadamente a do consumidor final, no seu desenvolvimento; ii) na identificação do desempenho das empresas de pequena dimensão e das empresas de grande dimensão, quais as relações, de complementaridade ou de predominância, que se estabelecem entre elas no quadro da l&D e da Inovação farmacêuticas. Para responder a estas questões recorremos à revisão da literatura conhecida, que complementámos com a análise empírica de casos relativos a empresas farmacêuticas, nacionais e estrangeiras, implantadas em território português.
The evolution of the pharmaceutical industry in the last decades, although integrated in the general frame of economical development, preserves its own autonomy, owing to the eminent social nature of its objectives of action against desease and death and of progressivo search for human physical and psychic well-being. Because on this realm nothing is unchangeable, the growing dregree of exigency as to the leveis of quality, efficiency and security in the sector implies a dynamic and creative approach from the supply side. Therefore, Research and Development and Innovation have been important motors of the pharmaceutical industry, as processes where the immaterial dimension prevails and exerts influence upon the behaviour of the other factors related to the innovating activities. Consequently, the scope of the present work is the pharmaceutical industry, in a context of economical globalization, with emphasis on the R&D and Innovation vectors, being its main objective the answer to two fundamental questions: 1) In a sector where Innovation and R&D, are essential, as it is the case of the pharmaceutical industry, to know the influence that the demand, and particularly the final consummer, may exercise on its development; 2) when identifying the performance of small and big companies, what kind of complementary and/or predominance relations are established among them within the ambit of R&D and pharmaceutical innovation. In order to answer these questions, we proceeded to the re- examining of known literature, which we completed with the empirical analisys of cases related to pharmaceutical companies, both national and foreign, operating in Portugal.

Full textAbstract:
The relevance of the Einstein constraint equations in physics is first presented. They arise in the initial-value formulation of general relativity, and must be satisfied by the metric and the extrinsic curvature of a Cauchy surface. Propagating the resulting tensor fields with the evolution equations is then equivalent to solving Einstein's field equation. The constraint equations consist of a system of two coupled nonlinear second-order PDEs. Well-posedness of the system is addressed, following the work of Y. Choquet-Bruhat. Some brief comments about global solutions are made.The conformal method is introduced. Using this approach, along with York splitting, the constraint equations now consist of a semilinear elliptic equation and a linear elliptic system that have to be solved for the conformal factor and a vector field.The main part of the thesis addresses the questions of existence and uniqueness of solutions to the Einstein constraint equations on three-dimensional compact Cauchy surfaces without boundary. The Yamabe classification turns out to be a key tool, and is presented. Then follows a thorough literature review of the results in the cases where the mean curvature, which is part of the prescribed data, is constant or near-constant. Recent articles on the case where the mean curvature is far-from-constant are discussed qualitatively. We then turn to a specific toy-model investigated by D.Maxwell where a family of three-parameters is used to consider different regimes on a Yamabe-null manifold. A similar approach is then used to explicitly work out some existence and uniqueness results on a Yamabe-positive manifold.Tout d'abord, le rôle des équations de contraintes d'Einstein en physique est présenté. Ces équations font partie de la formulation du problème de Cauchy de la relativité générale, et doivent être satisfaites par la métrique, ainsi que par la courbure extrinsèque moyenne d'une surface de Cauchy. Déterminer la propagation de ces champs tensoriels par les équations d'évolution équivaut à la résolution de l'équation de champ d'Einstein. Les équations de contraintes d'Einstein consistent en un système de deux EDP couplées non-linéaires de deuxième ordre. Le travail d'Y. Choquet-Bruhat démontrant que le problème est bien posé, est résumé. S'ensuivent quelques brefs commentaires concernants les solutions globales. La méthode conforme est exposée. L'utilisation de cette technique combinée à la décomposition de York tranforme les équations de contrainte en une équation semi-linéaire elliptique et un système linéaire elliptique, ayant pour inconnues le facteur conforme et un champ vectoriel.L'essentiel de la présente thèse se concentre sur les questions d'existence et d'unicité des solutions des équations de contraintes d'Einstein sur les variétés compactes tridimensionelles sans frontière. À cet effet, la classification de Yamabe est un outil important. Une revue de la littérature est alors détaillée dans les cas où la courbure moyenne, qui est une donnée prescrite, est constante, ou 'proche-de-constante'. Puis vient une présentation qualitative d'articles récents traitant du cas où la courbure moyenne est 'loin-de-constante'. On s'attarde ensuite sur un cas spécifique étudié par D.Maxwell, dans lequel une famille de trois paramètres est utilisée pour passer d'un régime à l'autre sur une variété Yamabe-nulle. Une approche similaire est ensuite utilisée pour obtenir des résultats d'existence et d'unicité explicites sur une variété Yamabe-positive.

Hogan, Stephen P. "Creating parental trust in children's toy brands : the antecedents and dimensions of trustworthy behaviour of toy companies." Thesis, Brunel University, 2006. http://bura.brunel.ac.uk/handle/2438/5332.
Full textAbstract:
Based around a case study of the traditional toy industry, the research examines how companies create trust with parents, the main toy purchasers, and the importance of ethical behaviour in trust development when a vulnerable community is involved. Previous literature has revealed that trust leads to mutually beneficial company-consumer relationships but scholars have failed to agree on its definition, dimensions or measurement due to its complexity, diversity and intangibility. Few have distinguished between 'trustworthiness' as a moral quality of organisations and 'trust', which is a consumer judgement about companies and brands, made as part of their purchase deliberations. A review of the literature led to the development of a framework of trustworthy behaviour identifying five sets of antecedents (organisational, individual, control, relational and branding factors) and four key dimensions with related variables - 'Integrity' and 'Benevolence', relating to ethical constructs and 'Commitment' and 'Satisfaction', relating to organisational constructs. The model was then substantiated through qualitative research with a sample of senior managers in 12 leading toy companies and other stakeholders including industry body representatives, retailers and parents. The findings revealed that in a challenging economic climate, trust in toy companies is being driven principally by the marketing offer and by external influencers such as legislators, retailers, licensors, and the media. Examples of good ethical practices were identified, although often unnoticed by consumers, and the worthier companies, for whom trustworthiness was important, appeared to be faring less well economically than companies selling third party brands. Consumers' trust was significant in the preschool market but diminished in importance as children matured when their influence overrode parents' more rational purchase considerations. The research revealed a paradox that parents as well as children are vulnerable consumers who are often bypassed in the marketing process. Whatever children's consumer rights, there will always be a lack of trust in the industry whilst young children rather than parents are so blatantly targeted.

This master thesis aims to put an abstract view on culture and leadership in China considering the context of a Chinese society, which is adapting and transforming within the age of globalization and a rapid economic development. The goal of our research is to investigate on influences, trends and manifestations, which help to characterize the foundation and exercise of leadership in China. In order to be able to answers our research questions, we travelled for six weeks to China to conduct in-depth interviews with 15 Chinese leaders in Shanghai and Beijing in order to draw conclusion from the utterances we were able to grasp. Many researchers try to oversimplify the Chinese culture and society as well as its approach to leadership. For this reason we tried to underline the complexity of conducting business in China, and what factors need to be taken into consideration in order to have a successful encounter. The key findings of our thesis are that it is hard to simplify the phenomenon leadership in China, since it highly depends upon the observed company, and also the generation of the leader or follower one is dealing with. Furthermore, it is important to keep in mind the complex and rich culture of China, which goes several hundreds of years and has still a huge impact on behavior of today’s Chinese.

The mixed-mode modelling methodology is essential to extend the benefit of computer-aided design (CAD) techniques to the design of power electronic circuits. The mixed-mode environment can be established in two ways. One is through adopting device circuit models into the two-dimensional device simulator. The other is through introducing finite-element device models into the circuit simulator. In the first method, an effective numerical algorithm has been proposed for adopting advanced compact models for power devices into a general-purpose two-dimensional mixed-mode device/circuit simulator. A suite of compact models for major power devices are implemented into the simulator and validated. In the second method, simplified numerical models for power diodes and insulated gate bipolar transistors (IGBT) for the circuit simulator Saber is proposed. Comparisons of the new models with the other compact model and the experimental result are made and show good agreement. It is also shown that the speed of the numerical models can be increased enormously to be comparable with the speed of other compact models in some cases by using specific numerical techniques. Techniques for measuring fast power devices and extracting the parameters are studied and enhanced, a commercial IGBT device is measured, the parameter extraction procedure applied and device characterised. Two-dimensional device simulation has been used extensively for understanding the devices and to help in the compact model development. Two-dimensional numerical analysis of the quasi-saturation phenomenon in the vertical double-diffused MOS (VDMOS) device is carried out and improved design proposed.

This dissertation aims to analyse the link between companies and the observance of ethical standards. The issue explored in this dissertation wonders if ethics would represent a new value under which would be raising another dimension of human rights, the fourth, and if this value would now be required in business activities. It starts with the theory of dinamogenesis of human rights focusing the analyses of the exercise of power as the trigger of the demands that leads to the establishment of rights of, liberty, equality and fraternity/solidarity, proclaimed at the speech do Karel Vasak (1979). After that, is analysed the raising of a new dimension of human rights, based on ethics to confront the demands stated by economy globalization, revolution in information technology and in biogenetics. This study also explores the analysis of sustainability recommended in the Brundtland Commission Report (1987 – UN) and its dissemination to the corporative scope, through the observance of the 'tripple bottom line' which links the company's perpetuation with respect for the environmenteconomic efficiency and impact of their activities on society. Is still analysed the functionalization of the Law related to the companies, observing the social e solidary function dictated constitutionally, exploring the relation of the company with ethics as a function. After clarifying internal institutes of the brazillian constitution (such as the Bankruptcy Law – Law 11,101/05 and the Law of Solid Waste National Policy – Law 12,305/10), which exemplify the legal guarantee of the social function and solidarity dictated constitutionally, It moves to the analysis of corporate governance in its relation to ethics, approaching the inclusion of prescribed tools in this institute, such as compliance and Code of Ethics in Corporate Law – Law 6,404/76 and Anti-Corruption Law – Law 12,846/13; which confirms the hypothesis raised that the business activity has been suffering demands of ethic nature, which is already justifying the enactment of laws under which such value is present. It started from literature supported by the hypothetical deductive method and literature review for research aiming to analyze and answer the question posed.
A presente dissertação tem por objeto de análise a vinculação das empresas com a observância de parâmetros éticos. A problemática colocada questiona se a ética afigurar-se-ia como um novo valor sob o qual estaria se erigindo uma outra dimensão, a quarta, dos direitos humanos; e se esse valor estaria também sendo exigido nas atividades empresariais. Parte-se da teoria da dinamogenesis dos direitos humanos tendo sob foco a análise do exercício do poder como deflagrador de demandas que culminaram com o estabelecimento de direitos de liberdade, igualdade e fraternidade/solidariedade, proclamados no discurso de Karel Vasak (1979). Em seguida, aborda-se o surgimento de uma dimensão dos direitos humanos fundada na ética para fazer frente às demandas ditadas pela globalização econômica, revolução da área da tecnologia da informação e da biogenética. O estudo contempla, também, a análise da sustentabilidade preconizadas no Relatório da Comissão Brundtland (1987 – ONU) e sua disseminação para o âmbito da empresa, mediante a observância do triple bottom line, que vincula a perenização da empresa com o respeito ao meio ambiente, à eficiência econômica e aos impactos da sua atividade na sociedade. Analisa-se, ainda, a funcionalização do direito em relação à empresa em observância às funções social e solidária, ditadas constitucionalmente, investigando-se a relação da empresa com a função ética. Após trazer a lume institutos infraconstitucionais (como a Lei de Falências – Lei 11.101/05 e a e a Lei da Política Nacional dos Resíduos Sólidos – Lei 12.305/10), que exemplificam a garantia legal da função social e solidária ditadas constitucionalmente, passa-se à análise da governança corporativa em sua vinculação com a ética, abordando-se a inserção de ferramentas prescritas nesse instituto, tais como compliance e Código de Ética na Lei das Sociedades Anônimas – Lei 6.404/76 e na Lei Anticorrupção – Lei 12.846/13, o que confirma a hipótese suscitada de que a atividade empresarial vem sofrendo demandas de natureza ética, o que já vem justificando a edição de leis nas quais tal valor se faz presente. Partiu-se de pesquisa bibliográfica apoiada no método hipotético dedutivo e revisão da literatura para a investigação visando a analisar e responder à questão proposta.

Full textAbstract:
Historical, well developed, procedures for RF design have minimal emphasis on exploring the third dimension due to the difficulty of fabrication. Recent material advancements applicable to 3D printing have brought about low-loss thermoplastics with excellent mechanical properties. Research into depositing conductive inks onto arbitrary 3D shapes has achieved resolutions better than 50 μm with conductivity values approaching that of copper cladding. The advancements in additive manufacturing have improved reliability and repeatability of three dimensional designs while decreasing fabrication time. With this design approach other considerations, such as stability and strength, can be concentrated on during the structure design to realize new shapes. The next step in the future of RF research will encompass designing and further understanding the benefits and consequences of using all three dimensions. This could include meandering an antenna element around other electronic components to make the overall package size smaller or integrating an antenna array into a wing.
The design and analysis of the periodic spiral antenna (PSA) takes a look at a specific case of full volume utilization. In this application meandering in the z-dimension allowed the design to become smaller and more efficient than what is achievable with planar methods. This thesis will go into detail on the characterization of the periodic spiral antenna. To exemplify the benefits of meandering in the z-dimension a loop antenna is presented and benchmarked against other miniaturization techniques. Measured results of two different PSA models are presented and remarks on improving fabrication are given. When an antenna is used as a transmitter incident power will cause thermal generation so a study was conducted to understand how material properties can govern the amount of heat generated.

Within artificial intelligence and robotics there is considerable interest in how a single agent can autonomously make sequential decisions in large, high-dimensional, uncertain domains. This thesis presents decision-making algorithms for maximizing the expected sum of future rewards in two types of large, high-dimensional, uncertain situations: when the agent knows its current state but does not have a model of the world dynamics within a Markov decision process (MDP) framework, and in partially observable Markov decision processes (POMDPs), when the agent knows the dynamics and reward models, but only receives information about its state through its potentially noisy sensors. One of the key challenges in the sequential decision making field is the tradeoff between optimality and tractability. To handle high-dimensional (many variables), large (many potential values per variable) domains, an algorithm must have a computational complexity that scales gracefully with the number of dimensions. However, many prior approaches achieve such scalability through the use of heuristic methods with limited or no guarantees on how close to optimal, and under what circumstances, are the decisions made by the algorithm. Algorithms that do provide rigorous optimality bounds often do so at the expense of tractability. This thesis proposes that the use of parametric models of the world dynamics, rewards and observations can enable efficient, provably close to optimal, decision making in large, high-dimensional uncertain environments.
(cont.) In support of this, we present a reinforcement learning (RL) algorithm where the use of a parametric model allows the algorithm to make close to optimal decisions on all but a number of samples that scales polynomially with the dimension, a significant improvement over most prior RL provably approximately optimal algorithms. We also show that parametric models can be used to reduce the computational complexity from an exponential to polynomial dependence on the state dimension in forward search partially observable MDP planning. Under mild conditions our new forward-search POMDP planner maintains prior optimality guarantees on the resulting decisions. We present experimental results on a robot navigation over varying terrain RL task and a large global driving POMDP planning simulation.

Full textAbstract:
Data mining is an essential part of knowledge discovery, and performs the extraction of useful information from a collection of data, so as to assist human beings in making necessary decisions. This thesis describes research in the field of itemset mining, which performs the extraction of a set of items that occur together in a dataset, based on a user specified threshold. Recent focus of itemset mining has been on the discovery of closed itemsets from high-dimensional datasets, characterised by relatively few rows and a relatively larger number of columns. A closed itemset is the maximal set of items common to a set of rows. By exponentially increasing running time as the average row length increases, mining closed itemsets from such datasets renders most column enumeration-based algorithm impractical. Existing row enumeration-based algorithms also show that they struggle to reach large cardinality closed itemsets. This is due to the implementation of the support constraint, which is based on the frequency of occurrence of the itemset. Frequent closed itemsets are usually smaller in size and larger in numbers, hence taking much of the memory space. Unfortunately, large cardinality closed itemsets are likely to be more informative than small cardinality closed itemsets in this type of dataset. The research investigates the area of large cardinality closed itemset discovery by examining and analysing the literature and identifying both strengths and weaknesses of existing approaches. Based on this synthesis, a new algorithm, termed DisClose, has been designed and developed to discover large cardinality (colossal) closed itemsets from high-dimensional datasets. The algorithm strategy begins by enumerating large cardinality itemsets and from these, builds smaller itemsets. This is done by applying a bottom-up search of the row-enumeration tree. A minimum cardinality threshold has been proposed to identify colossal closed itemsets and to further reduce the search space. A novel closedness-checking method has been proposed which uses a unique generator to immediately discover closed itemsets without the need to check if each new closed itemset has previously been found. These approaches have been combined using a Compact Row-Tree (CR-Tree) data structure designed to assist in the efficient discovery of the colossal closed itemsets. For evaluation purposes four state-of-the-art algorithms have been selected for comparison. Experimental results show that algorithm DisClose is scalable and can efficiently extract colossal closed itemsets in the considered dataset, even for low support thresholds that existing algorithms cannot find.

Full textAbstract:
Purpose: The purpose of this study is to investigate how and to what degree Swedish multinational companies (MNCs) adapt to local conditions when they establish subsidiaries in China, and if cultural differences play an important role in their operations. Background: The major challenge for MNCs establishing abroad is the configuration and integration of their country subsidiaries (Galbraith, 2000). Therefore, it is vital to understand how activities within an organization, such as structures, processes, reward systems, and people practices, should be designed in order for the company to be as efficient as possible (Weiss, 2007; Kesler & Kates, 2011). Swedish direct investments in China have increased significantly in the late 2000s, especially in the eastern regions, where a majority of about 650 Swedish companies in China are located (Swedish Trade Council, 2012a). Establishing across borders is a step towards future growth, but it is important to note that a cross-border expansion comes with many challenges (Galbraith, 2000). Method: This study uses a qualitative research method by investigating the experiences and practices of two Swedish multinational companies with operations in Shanghai, China. Information has been collected from eight respondents in the form of interviews and open-ended questionnaires. Conclusion: Swedish MNCs standardize their organization to a large extent when they establish subsidiaries in China, and culture has a slight influence on the practices of Swedish MNCs but does not play a major role for the business as a whole.

Full textAbstract:
La dimension objective représente l’une des principales théories d’interprétation des droits fondamentaux en Allemagne. Peu connue en dehors de son cadre national, elle se déploie toutefois au niveau européen et en particulier dans la jurisprudence de la Cour européenne, sans être pensée en tant que telle. La présente étude vise à analyser cette conception à l’échelle européenne à travers ses caractéristiques essentielles dégagées à partir du droit allemand, et mettre en évidence l’influence de ce dernier sur le droit européen. La dimension objective se présente ainsi comme une interprétation téléologique et totale, qui indexe la protection des droits sur des valeurs politiques et morales, et assure leur rayonnement au sein mais aussi à travers les ordres juridiques. Si elle constitue un point d’orgue dans la sophistication de la théorie des droits, elle emporte néanmoins le risque de relativiser ces derniers dans leur fonction subjective de protection des libertés individuellesThe objective dimension is one of the main theories of the interpretation of fundamental rights in Germany. Although relatively unknown outside its national context, it exerts an influence at a European level, especially in case-law in the European Court of Human Rights, without being regarded as such. The present study aims to analyze this approach of rights at a European scale through its main characteristics drawn from German law, as well as to highlight the influence of the latter on European law. The objective dimension appears to be a teleological and total interpretation that establishes the protection of rights on certain political and moral values, and ensures their radiating effect within but also through legal systems. If it is a breakthrough in the elaboration of the theory of rights, it also carries the risk of weakening these same rights in their subjective function which is to protect personal freedom

La condensation a reflux intervient dans de nombreuses industries et permet de separer le composant le moins volatil des autres composes dans un melange de vapeur. Dans le but de reduire la consommation energetique, on utilise ce procede que l'on couple a une forte compacite du condenseur. Nous avons donc etudie le phenomene de reflux dans des canaux rectangulaires de faible diametre hydraulique. Ce mode de condensation ainsi que la geometrie presentent des particularites qui rendent delicat le dimensionnement des condenseurs. L'etude experimentale du phenomene d'engorgement en eau-air a contre-courant a montre que la repartition des debits dans un condenseur compact est aleatoire. Ainsi, l'engorgement n'est pas generalise a tous les canaux. Nous avons quantifie ce phenomene par deux correlations dependantes du debit d'eau qui simulent bien nos resultats experimentaux. La confrontation des donnees experimentales de la condensation de l'air humide a un modele fonde sur la theorie du film montre que les choix de nos correlations pour simuler les transferts de chaleur et de masse sont adaptes. Enfin, le reflux se manifeste en distinguant des zones preferentielles de condensation et des zones assechees ou depourvues de condensation.

Frågeställning: Vilka leveransdimensioner är det som påverkar kundlojaliteten mot ett onlineföretag? Syfte: Syftet med studien är att undersöka vilka leveransdimensioner det är som påverkar kundlojaliteten mot ett onlineföretag utifrån ett konsumentperspektiv. Denna studie ämnar att studera vilka leveransdimensioner som i förhållande till förtroende påverkar kundlojaliteten inom e-handeln. Metod: En kvantitativ forskningsstrategi med en deduktiv ansats genom en enkätundersökning med frågor ur tidigare forskning har utförts vid insamling av primärdata. En teorimodell med tillhörande hypoteser utformades utifrån studiens teoretiska referensram. Det totala urvalet inkluderade 255 respondenter varav 14 var bortfall. Resultatet analyserades genom korrelations- och multivariat regressionsanalys i IBM SPSS-Statistics. Slutsats: Studien visade att samtliga leveransdimensioner hade ett signifikant samband med kundlojalitet och förtroende utifrån korrelationsanalysen. I regressionsanalysen påvisades en indikation på ett kausalt samband mellan leveranstrovärdighet och kundlojalitet i förhållande till förtroende. Indikation på kausalitet framfördes även mellan hållbar leverans och kundlojalitet i förhållande till förtroende. Förtroendet visades vara avgörande för kundlojaliteten mot ett onlineföretag inom ett sammanhang med leveransdimensioner. Därmed visade studiens resultat att de leveransdimensioner som påverkar kundlojaliteten mot ett onlineföretag är leveranstrovärdighet och hållbar leverans.Research question: Which of the delivery dimensions affect customer loyalty to an online company? Purpose: The purpose of the study is to examine which delivery dimensions affect customer loyalty to an online company from a consumer perspective. This study aims to study which delivery dimensions in relation to trust affect customer loyalty in e-commerce. Method: A quantitative research strategy with a deductive approach through a survey with questions from previous research has been executed when collecting primary data. A theoretical model with associated hypotheses was designed based on the study's theoretical frame. The total sample included 255 respondents of which 14 were not included. The results were analyzed through correlation and multivariate regression analysis in IBM SPSS-Statistics. Conclusion: The study showed that all delivery dimensions had a significant relationship with customer loyalty and trust based on the correlation analysis. The regression analysis showed an indication of a causal relationship between delivery reliability and customer loyalty in relation to trust. Indication of causality was also presented between green delivery and customer loyalty in relation to trust. Trust was shown to be crucial for customer loyalty to an online company in a context of delivery dimensions. Thus, the results of the study showed that the delivery dimensions that affect customer loyalty to an online company are delivery reliability and green delivery.

Jonnalagadda, Krishna Praveen. "Influence of Graphite type on copper diffusion in P/M copper steels." Thesis, KTH, Materialens processteknologi, 2012. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-98264.
Full textAbstract:
One main reason for the use of Fe-Cu-C system in PM industry is the presence of liquid phase (copper) at the start of sintering (1120oC). The diffusion of liquid copper into iron causes swelling in the structure. This in turn can cause high dimensional change and, if not controlled properly, may cause distortion. So it is of paramount importance to control the copper diffusion. Carbon, added as graphite, reduces the swelling of copper by changing the dihedral angle. The affect of graphite on copper diffusion depends on the graphite type, particle size of graphite and heating rate. The aim of this work was to find the influence of graphite type and particle size of graphite on copper diffusion. Water Atomized iron (ASC100.29) produced in Höganäs AB was taken as the base powder. Two types of graphite were used each with two different particle sizes. Two different graphite quantities (0.2% & 0.8%) for each type was taken. Natural fine graphite (UF4), Natural coarse graphite (PG44), Synthetic fine graphite (F10) and Synthetic coarse graphite (KS44) were the graphites used in this work. Powders were compacted at 600 Mpa and the sintering was done at 1120oC for 30 minutes in 90/10 N2/H2. Dilatometry and metallographic investigation of the samples sintered in the production furnace were used to understand the graphite influence. The investigation showed that at low graphite levels (0.2%), the affect of graphite type or graphite size was not significant on copper diffusion. At high graphite levels (0.8%), synthetic graphites were more effective in reducing the swelling of copper. Influence of particle size of synthetic graphites on Cu diffusion was not significant compared to the influence of particle size of natural graphite. There was also a considerable affect of heating rate on graphite dissolution and copper swelling.

Mestrado em Gestão de Recursos HumanosO presente estudo tem como objetivo principal definir qual o tipo de Contrato Psicológico vigente num grupo de colaboradores de uma empresa multinacional do sector químico, que após um processo de downsizing recorreu ao redeployment como estratégia de reter alguns dos seus talentos possibilitando a sua recolocação em outras suas subsidiárias. Recorreu-se a uma metodologia mista, através de análise qualitativa de duas entrevistas e de análise quantitativa, através de análise de dados, após a sua recolha, através de um questionário online. Analisou-se o Contrato Psicológico em sete dimensões de cumprimento por parte do funcionário, cinco dimensões de cumprimento por parte da organização e três dimensões relativas à relação da organização com o funcionário, as transições no Contrato Psicológico. Estas dimensões agrupam-se em quatro tipos de contrato: Relacional, Transacional, Transitório e Equilibrado. Também se avaliou a quebra e a violação do Contrato Psicológico, através de escalas também já existentes e testadas para esse âmbito. Os resultados indicam a prevalência do contrato Relacional, composto pelas dimensões Estabilidade e Lealdade do funcionário e Lealdade da organização. Revelaram ainda que não existiu quebra ou rutura do Contrato Psicológico e que o tipo Transitório, que poderia ter obtido maiores valores dada a mudança que existiu para estes colaboradores, foi por sua vez, o mais baixo.
This study aimed to analyze the type of Psychological Contract present in a group of workers from a multinational company of the chemical sector which after a downsizing process, resorted redeployment as a retention strategy for some employees, relocating them in some other subsidiaries of the group. A mixed methodology was used, through qualitative analysis of two interviews and quantitative analysis, through data analysis, after collection, across an online questionnaire. The Psychological Contract was analyzed in seven dimensions of compliance by the employee, five dimensions of compliance by the organization and three dimensions on the organization's relationship with the employee, the transitions in the Psychological Contract. These dimensions are grouped into four types of contract: Relational, Transactional, Transitional and Balanced. It was also assessed the breach and violation of the Psychological Contract through scales already tested for this issue. The results revealed a highlight for the Relational Contract, composed of the dimensions? stability and loyalty of the employee and loyalty of the organization. The results revealed that there was no breach or disruption of the Psychological Contract and the Transitional type, which could have obtained higher values, given the change that existed for these employees, was in turn, the lowest.

Full textAbstract:
The continuous miniaturization of electronic systems using the three-dimensional (3D) integration technique has brought in new challenges for the computer-aided design and modeling of 3D integrated circuits (ICs) and systems. The major challenges for the modeling and analysis of 3D integrated systems mainly stem from four aspects: (a) the interaction between the electrical and thermal domains in an integrated system, (b) the increasing modeling complexity arising from 3D systems requires the development of multiscale techniques for the modeling and analysis of DC voltage drop, thermal gradients, and electromagnetic behaviors, (c) efficient modeling of microfluidic cooling, and (d) the demand of performing fast thermal simulation with varying design parameters. Addressing these challenges for the electrical/thermal modeling and analysis of 3D systems necessitates the development of novel numerical modeling methods.
This dissertation mainly focuses on developing efficient electrical and thermal numerical modeling and co-simulation methods for 3D integrated systems. The developed numerical methods can be classified into three categories. The first category aims to investigate the interaction between electrical and thermal characteristics for power delivery networks (PDNs) in steady state and the thermal effect on characteristics of through-silicon via (TSV) arrays at high frequencies. The steady-state electrical-thermal interaction for PDNs is addressed by developing a voltage drop-thermal co-simulation method while the thermal effect on TSV characteristics is studied by proposing a thermal-electrical analysis approach for TSV arrays.
The second category of numerical methods focuses on developing multiscale modeling approaches for the voltage drop and thermal analysis. A multiscale modeling method based on the finite-element non-conformal domain decomposition technique has been developed for the voltage drop and thermal analysis of 3D systems. The proposed method allows the modeling of a 3D multiscale system using independent mesh grids in sub-domains. As a result, the system unknowns can be greatly reduced. In addition, to improve the simulation efficiency, the cascadic multigrid solving approach has been adopted for the voltage drop-thermal co-simulation with a large number of unknowns.
The focus of the last category is to develop fast thermal simulation methods using compact models and model order reduction (MOR). To overcome the computational cost using the computational fluid dynamics simulation, a finite-volume compact thermal model has been developed for the microchannel-based fluidic cooling. This compact thermal model enables the fast thermal simulation of 3D ICs with a large number of microchannels for early-stage design. In addition, a system-level thermal modeling method using domain decomposition and model order reduction is developed for both the steady-state and transient thermal analysis. The proposed approach can efficiently support thermal modeling with varying design parameters without using parameterized MOR techniques.

Full textAbstract:
Various data structures have been proposed for representing the connectivity of manifold triangle meshes. For example, the Extended Corner Table (ECT) stores V+6T references, where V and T respectively denote the vertex and triangle counts. ECT supports Random Access and Traversal (RAT) operators at Constant Amortized Time (CAT) cost. We propose two novel variations of ECT that also support RAT operations at CAT cost, but can be used to represent and process Simplicial 2-Complexes (S2Cs), which may represent star-connecting, non-orientable, and non-manifold triangulations along with dangling edges, which we call sticks. Vlist stores V+3T+3S+3(C+S-N) references, where S denotes the stick count, C denotes the number of edge-connected components and N denotes the number of star-connecting vertices. Ering stores 6T+3S+3(C+S-N) references, but has two advantages over Vlist: the Ering implementation of the operators is faster and is purely topological (i.e., it does not perform geometric queries). Vlist and Ering representations have two principal advantages over previously proposed representations for simplicial complexes: (1) Lower storage cost, at least for meshes with significantly more triangles than sticks, and (2) explicit support of side-respecting traversal operators which each walks from a corner on the face of a triangle t across an edge or a vertex of t, to a corner on a faces of a triangle or to an end of a stick that share a vertex with t, and this without ever piercing through the surface of a triangle.

Après l’illustration des notions découlant du principe de légalité et du principe de sécurité juridique, qui ont été élaborées dans le deux Pays, les cas jurisprudentiels et normatifs plus récents du droit italien et français sont étudiés. Ils concernent notamment le changement normatif qui intervient soit pendant la procédure administrative non contentieuse et qui est finalisée à l’adoption d’un acte favorable, soit pendant le développement de situations en cours, en affectant l’efficacité d’un acte individuel à effet durable. Cette reconstruction permet de catégoriser les hypothèses dans lesquelles la reconnaissance de la confiance légitime du privé soit juridiquement possible, ainsi que de vérifier les moyens de protection de ces positions subjectives, mises à la disposition par l’Italie et la France. Enfin, on analyse les solutions dégagées sur le thème au niveau européen, par la Cour de Justice de l’Union européenne, la Cour Européenne du Droit de l’Homme, ainsi que parle système de droit allemande, qui est devenu un modèle de référence en matière de confiance légitime au niveau européen. La recherche est donc destinée à évaluer l’adéquation de ces deux systèmes de droit aux impulsions de l’Union européenne et à vérifier leur aptitude au respect des standards européens d’effectivité de protectionThe dissertation examines the impact of new legislation that negatively affects the asset of private interests, carried out by administrative action. The comparative analysis focuses on the Italian and French legal systems, as they share a similar legal tradition in the field of administrative law. The work is aimed at verifying, through the study of the most recent case law, the existence of a position of legitimate expectation recognised to the administrated subjects with respect to the modification of laws over time, under two different aspects : within a proceedings, as well as during on-going situation created by provisions of long-lasting bindingness. The work analyses the available means of protection and it verifies the current position on the matter in the aforementioned normative systems. In the last part, the work studies the inputs on the subject matter given by the decisions of the European Court of Justice and the European Court of Human Rights, taking the analysis to a supra-national level; it also highlights the influence exercised by the German law on the issue of legitimate expectation, as the German system represent the principal referring model

Full textAbstract:
This PhD work was motivated by the CEA R&D program to provide solid technological basis for the use of Brayton power conversion system in Sodium-cooled Fast nuclear Reactors (SFRs). Multi-channel compact heat exchangers are necessary for the present application because of the low heat transfer capacity of the gas foreseen. In ASTRID project, a minimum size of Na channels section is required to avoid the plugging risk. However, this induces very low pressure losses in the bundle. Considering an additional inlet flow condition, a real risk of bad flow distribution remains. As a result, the thermal performance and thermal loading of the heat exchanger degrades due to it. The main goal of this work was to overcome the flow maldistribution problem by means of an innovative design of sodium distribution system (PATENT FR1657543), the development of a numerical strategy and the construction of an experimental database to validate all theoretical studies. The innovative sodium distribution system consists on an inlet header which tries to guide the evolution of the impinging jet flow while a system of bifurcating pre-distribution channels increases pressure drops in the bundle. Lateral communications between pre-distribution channels are introduced to further homogenize the flow. Two experimental facilities have been conceived to study the flow behavior in bifurcating channels and in the inlet header, respectively. At the same time, their effect on the flow distribution between channels is evaluated. The acquired PIV aerodynamic database allows to validate the numerical models and to prove the design basis for the proposed distribution system. Once having validated the CFD turbulence models and the strategy to study the flow maldistribution in the SGHE module, a decisive and trustworthy optimization of each component of the sodium distribution system has been performed. Finally, an optimal configuration has been proposed for the actual phase of ASTRID project.

Full textAbstract:
Face à la nature inconnue de l'énergie noire et de la matière noire, des modèles à champ scalaire léger ont été proposés pour expliquer l'accélération tardive de l'expansion de l'Univers et l'apparente abondance de matière non baryonique dans l'Univers. Dans une première partie, cette thèse confronte de la façon la plus précise possible les données de cosmologie les plus récentes au modèle du Galiléon, une théorie de gravité modifiée possédant des propriétés théoriques particulièrement intéressantes. Des contraintes observationnelles sur les paramètres du modèle sont dérivées en utilisant les dernières mesures liées aux distances cosmologiques et à la croissance des grandes structures de l'Univers. Un bon accord est observé entre les données et les prédictions théoriques, faisant du Galiléon un modèle alternatif compétitif avec celui de la constante cosmologique. Dans une seconde partie, la production de Branons, particules scalaires candidates au statut de matière noire venant d'une théorie de dimensions supplémentaires, est recherchée dans les collisions proton-proton enregistrées en 2012 par l'expérience Compact Muon Solenoid auprès du Grand Collisionneur de Hadrons. Des événements présentant un photon et de l'énergie transverse manquante dans l'état final sont sélectionnés dans les données et comparés aux estimations des bruits de fonds attendus. Aucun excès d'événements n'étant observé, des limites expérimentales sur les paramètres de la théorie du Branon sont calculées. Elles sont les plus contraignantes à ce jour. Cette thèse se conclut par des arguments pour une description unifiée des deux modèles étudiés, dans le cadre des théories de dimensions supplémentairesThe nature of dark energy and dark matter is still unknown today. Light scalar field models have been proposed to explain the late-time accelerated expansion of the Universe and the apparent abundance of non-baryonic matter. In the first part of this thesis, the Galileon theory, a well-posed modified gravity theory preserving the local gravitation thanks to the Vainshtein screening effect, is accurately tested against recent cosmological data. Observational constraints are derived on the model parameters using cosmological distance and growth rate of structure measurements. A good agreement is observed between data and theory predictions. The Galileon theory appears therefore as a promising alternative to the cosmological constant scenario. In the second part, the dark matter question is explored through an extra-dimension theory containing massive and stable scalar fields called Branons. Branon production is searched for in the proton-proton collisions that were collected by the Compact Muon Solenoid experiment in 2012 at the Large Hadron Collider. Events with a single photon and transverse missing energy are selected in this data set and compared to the Standard Model and instrumental background estimates. No signature of new physics is observed, so experimental limits on the Branon model parameters are derived. This thesis concludes with some ideas to reach an unified description of both models in the frame of extra-dimension theories

In the fisrt part of this work we investigate the modified Yamabe problem on four-dimensional manifolds whose the modifiers invariants depending on the eigenvalues of the Weyl curvature tensor and they are described in terms of maximum and minimum of the biorthogonal (sectional) curvature. We provide some geometrical and topological properties on four-dimensional manifolds in terms of these invariants. In the second part we investigate the critical points of the total scalar curvature functional restricted to space of metrics with constant scalar curvature of unitary volume, for simplicity CPE metrics. It was conjectured in the 1980’s that every CPE metric must be Einstein. We prove that such a conjecture is true under a second-order vanishing condition on the Weyl tensor.
Na primeira parte deste trabalho investigamos o problema de Yamabe modificado em variedades de dimensão quatro cujos invariantes modificadores dependem dos autovalores do tensor de Weyl e são descritos em termos do máximo e mínimo da curvatura biortogonal (seccional). Fornecemos algumas propriedades geométricas e topológicas para tais variedades em termos destes invariantes. Na segunda parte investigamos os pontos críticos do funcional curvatura escalar total restrito ao espaço de métricas com curvatura escalar constante e volume unitário, abreviadamente chamamos de métricas CPE. Conjecturou-se na década de 1980 que toda métrica CPE deve ser Einstein. Provamos que tal conjectura é verdadeira sob uma condição de nulidade sobre o divergente de segunda ordem do tensor de Weyl.

Cities are becoming bigger, and questions about accessibility to the urban areas is a concern. Difficulties in finding affordable accommodation is one, and another one is wellbeing in homes. With the recent interests in the increasing tiny house movement, living solutions that are affordable, simple, and small are gaining in popularity. This is happening partly as a reaction to that the average home size in many parts of the western world have been increasing dramatically in the last decades. Both building regulation institutions and research are often connecting small space living with negative effects on wellbeing. But the tiny house movement seem to show that people can live well also in small dwellings outside of such regulations. The question of what brings wellbeing to a homes has never been more relevant, and the area of small and unconventional housing is lacking research. Research question: What is wellbeing living in small and unconventional homes? Purpose: The purpose of this study is to increase the understanding of wellbeing in small and unconventional homes. The objective of this research is to provide a holistic understanding of wellbeing in such homes, by going beyond firstspace and secondspace dimensions, into a thirdspace perspective. Method: Semi-structured, face-to-face interviews and observations of people chosing to live in small and unconventional dwellings. A thematical analysis strategy suitable for new concept development was adopted. An abductive approach was applied in order to frame the study being multi disciplinary, and in order to obtain increased understandings of the study phenomenon. However, the study focused heavily on the empirical data from my study. Conclusion: This study found that the wellbeing is experienced as a totality of different dimensions: not only does the physical dwelling in itself provide for wellbeing, but also dimensions relating to thoughts, meanings and lived experiences they associate to their dwellings. A holistic perspective is what best can provide an understanding of their experienced wellbeing, where physical, mental and lived dimensions are combined. Furthermore was found that the dwellings can work as facilitators to achieve wellbeing on several levels both relating to their inner space in their dwellings, bringing in other spatialities, and for their lives as a whole. Keywords: Small space living, tiny house movement, experienced wellbeing at home, housing beyond traditions and conventions, influences of spatialities, spatial theory

La première est définie par la interaction électrostatique provenant de la loi de Gauss. La deuxième est la structure déterminantale disponible que pour des valeurs précises de la température. La troisième est le principe de minimisation de l'énergie libre en physique, qui permet étudier des modèles plus généraux. Ces travaux conduisent à des nombreux questions ouvertes et à une famille de modèles d'intérêtWe explore probabilistic models usually called Coulomb gases. They arise naturally in mathematics and physics. We can mention random matrix theory, the Laughlin fractional quantum Hall effect and the Ginzburg-Landau systems of superconductivity. In order to better understand the role of the ambient space, we study geometric versions of such systems. We exploit three structures. The first one comes from the electrostatic nature of the interaction given by Gauss's law. The second one is the determinantal structure which appears only for a specific temperature. The third one is the minimization of the free energy principle, coming from physics which gives us a tool to understand more general models. This work leads to many open questions on a whole family of models which can be of independent interest.)

Les procédés bipolaires semi-conducteurs complémentaires à oxyde de métal (BiCMOS) peuvent être considérés comme étant la solution la plus généralepour les produits RF car ils combinent la fabrication sophistiquée du CMOSavec la vitesse et les capacités de conduction des transistors bipolaires silicium germanium(SiGe) à hétérojonction (HBT). Les HBTs, réciproquement, sontles principaux concurrents pour combler partiellement l'écart de térahertzqui décrit la plage dans laquelle les fréquences générées par les transistors etles lasers ne se chevauchent pas (environ 0.3 THz à 30 THz). A_n d'évaluerles capacités de ces dispositifs futurs, une méthodologie de prévision fiable estsouhaitable. L'utilisation d'un ensemble hétérogène d'outils et de méthodes desimulations permet d'atteindre successivement cet objectif et est avantageusepour la résolution des problèmes. Plusieurs domaines scientifiques sont combinés, tel que la technologie de conception assistée par ordinateur (TCAO),la modélisation compacte et l'extraction des paramètres.Afin de créer une base pour l'environnement de simulation et d'améliorerla confirmabilité pour les lecteurs, les modèles de matériaux utilisés pour lesapproches hydrodynamiques et de diffusion par conduction sont introduits dèsle début de la thèse. Les modèles physiques sont principalement fondés surdes données de la littérature basées sur simulations Monte Carlo (MC) ou dessimulations déterministes de l'équation de transport de Boltzmann (BTE).Néanmoins, le module de TCAO doit être aussi étalonné sur les données demesure pour une prévision fiable des performances des HBTs. L'approchecorrespondante d'étalonnage est basée sur les mesures d'une technologie depointe de HBT SiGe pour laquelle un ensemble de paramètres spécifiques àla technologie du modèle compact HICUM/L2 est extrait pour les versionsdu transistor à haute vitesse, moyenne et haute tension. En s'aidant de cesrésultats, les caractéristiques du transistor unidimensionnel qui sont généréesservent de référence pour le profil de dopage et l'étalonnage du modèle. Enélaborant des comparaisons entre les données de références basées sur les mesureset les simulations, la thèse fait progresser l'état actuel des prévisionsbasées sur la technologie CAO et démontre la faisabilité de l'approche.Enfin, une technologie future de 28nm performante est prédite en appliquantla méthodologie hétérogène. Sur la base des résultats de TCAO, leslimites de la technologie sont soulignéesBipolar complementary metal-oxide-semiconductor (BiCMOS) processescan be considered as the most general solution for RF products, as theycombine the mature manufacturing tools of CMOS with the speed and drivecapabilities of silicon-germanium (SiGe) heterojunction bipolar transistors(HBTs). HBTs in turn are major contenders for partially filling the terahertzgap, which describes the range in which the frequencies generated bytransistors and lasers do not overlap (approximately 0.3THz to 30 THz). Toevaluate the capabilities of such future devices, a reliable prediction methodologyis desirable. Using a heterogeneous set of simulation tools and approachesallows to achieve this goal successively and is beneficial for troubleshooting.Various scientific fields are combined, such as technology computer-aided design(TCAD), compact modeling and parameter extraction.To create a foundation for the simulation environment and to ensure reproducibility,the used material models of the hydrodynamic and drift-diffusionapproaches are introduced in the beginning of this thesis. The physical modelsare mainly based on literature data of Monte Carlo (MC) or deterministicsimulations of the Boltzmann transport equation (BTE). However, the TCADdeck must be calibrated on measurement data too for a reliable performanceprediction of HBTs. The corresponding calibration approach is based onmeasurements of an advanced SiGe HBT technology for which a technology specific parameter set of the HICUM/L2 compact model is extracted for thehigh-speed, medium-voltage and high-voltage transistor versions. With thehelp of the results, one-dimensional transistor characteristics are generatedthat serve as reference for the doping profile and model calibration. By performingelaborate comparisons between measurement-based reference dataand simulations, the thesis advances the state-of-the-art of TCAD-based predictionsand proofs the feasibility of the approach.Finally, the performance of a future technology in 28nm is predicted byapplying the heterogeneous methodology. On the basis of the TCAD results,bottlenecks of the technology are identified
Bipolare komplementäre Metall-Oxid-Halbleiter (BiCMOS) Prozesse bietenhervorragende Rahmenbedingungen um Hochfrequenzanwendungen zurealisieren, da sie die fortschrittliche Fertigungstechnik von CMOS mit derGeschwindigkeit und Treiberleistung von Silizium-Germanium (SiGe) Heterostruktur-Bipolartransistoren (HBTs) verknüpfen. Zudem sind HBTs bedeutendeWettbewerber für die teilweise Überbrückung der Terahertz-Lücke, derFrequenzbereich zwischen Transistoren (< 0.3 THz) und Lasern (> 30 THz).Um die Leistungsfähigkeit solcher zukünftigen Bauelemente zu bewerten, isteine zuverlässige Methodologie zur Vorhersage notwendig. Die Verwendungeiner heterogenen Zusammenstellung von Simulationstools und Lösungsansätzenerlaubt es dieses Ziel schrittweise zu erreichen und erleichtert die Fehler-_ndung. Verschiedene wissenschaftliche Bereiche werden kombiniert, wie zumBeispiel der rechnergestützte Entwurf für Technologie (TCAD), die Kompaktmodellierungund Parameterextraktion.Die verwendeten Modelle des hydrodynamischen Simulationsansatzes werdenzu Beginn der Arbeit vorgestellt, um die Simulationseinstellung zu erläuternund somit die Nachvollziehbarkeit für den Leser zu verbessern. Die physikalischenModelle basieren hauptsächlich auf Literaturdaten von Monte Carlo(MC) oder deterministischen Simulationen der Boltzmann-Transportgleichung(BTE). Für eine zuverlässige Vorhersage der Eigenschaften von HBTs muss dieTCAD Kon_guration jedoch zusätzlich auf der Grundlage von Messdaten kalibriertwerden. Der zugehörige Ansatz zur Kalibrierung beruht auf Messungeneiner fortschrittlichen SiGe HBT Technologie, für welche ein technologiespezifischer HICUM/L2 Parametersatz für die high-speed, medium-voltage undhigh-voltage Transistoren extrahiert wird. Mit diesen Ergebnissen werden eindimensionaleTransistorcharakteristiken generiert, die als Referenzdaten fürdie Kalibrierung von Dotierungspro_len und physikalischer Modelle genutztwerden. Der ausführliche Vergleich dieser Referenz- und Messdaten mit Simulationengeht über den Stand der Technik TCAD-basierender Vorhersagenhinaus und weist die Machbarkeit des heterogenen Ansatzes nach.Schlieÿlich wird die Leistungsfähigkeit einer zukünftigen Technologie in28nm unter Anwendung der heterogenen Methodik vorhergesagt. Anhand derTCAD Ergebnisse wird auf Engpässe der Technologie hingewiesen

“The squeaky wheel gets the grease” is an American proverb used to convey the notion that only those who speak up tend to be heard. This was believed to be the case at the telecom company I interned at – they believed that while those who complain about an issue (in particular, an issue of no access to the service) get their problem resolved, there are others who have an issue but do not complain about it. The latter are likely to be dissatisfied customers, and must be identified. This report describes the approach taken to address this problem using machine learning. Unsupervised learning was used to segment the customer base into user profiles based on their viewing behaviour, to better understand their needs; and supervised learning was used to develop a predictive model to identify customers who have no access to the TV service, and to explore what factors (or combination of factors) are indicative of this issue.

In recent years, the price of steam coal has risen substantially, thus causing a large increase in the cost of purchasing coal. How risks can be distributed and costs be reduced are issues viewed with great importance by the Taiwan Power Company. However, purchasing contracts of the Taiwan Power Company are trade secrets, and data on prices is difficult to obtain. Thus, related studies mainly analyze the storing and transportation of coal. This study utilizes the contracts and commodity prices of the “Bidding Announcement” of the “Government Electronic Purchasing Network” combined with concepts of portfolio theory to analyze how the Taiwan Power Company distributes risks associated with purchasing coal. With regard to the supply of coal, the Taiwan Power Company mainly imports coal from Indonesia, Australia, and China. Factors affecting the supply of coal mainly lie in weather conditions and internal demand problems of exporting countries, including 1.Indonesia promoting domestic coal supplying obligations in order to sufficiently meet domestic demand, 2. Australia setting export quotas because of severe harbor blockages at Newcastle harbor, and 3. China’s coal supply not meeting its demand due to economic development and being a net import country since 2007. The coal purchasing methods of the Taiwan Power Company are mainly through contracts and the purchase of preexisting goods. Purchases completed through contracts are stipulated to be between 60%~85% of the total, while the purchases of preexisting coal is set to be 15%~40% of the total. Also, due to policy, the imported volume from China (whether through contracts or purchasing preexisting coal) cannot exceed 30% of the total. This study uses the coal purchasing strategy of the Taiwan Power Company as an example and constructs a coal purchasing strategy that takes into account coal price risks. This study applies concepts of portfolio theory in conjunction with mathematical planning with minimizing the “current value of coal purchasing costs after risk adjustment” as the goal. Three limitations are considered , including 1. the coal supply limitation, 2. the coal import source country limitation, and 3. the power plant coal use limitation. Also, situational analysis through the use of models is performed on coal purchasing combinations affected by various risks and external factors. Recommendations for power companies are then provided for their reference. The results of the model show that, considering the minimization of costs, the import ratio difference of this study does not exceed 5.5% of the Taiwan Power Company’s import ratio. Thus, the model used in this study can be trusted. Considering risk factors and variations in external factors, using Australian contracts and Chinese contracts can spread out import sources to avoid risks associated with relying on Indonesian preexisting coal. However, the proposals of using Chinese preexisting coal and Australian preexisting coal are not used in the combination due to higher prices or relevance. The theoretical model constructed by this study combines portfolio theory and Taiwan Power Company strategy into risk concepts of portfolio theory, and brings related supply and demand limitations, Taiwan Power Company coal purchasing strategy, and the coal burning machine coal use limitation into consideration. However, as the price data is not the actual price data of the Taiwan Power Company, a considerable error may exist in the results.

This study takes the steel wires manufacturer as the object and explores the customer’s view and evaluation of the service quality of the product providers. Varying from regularly seen methods for the quality evaluation of customer services, this study applies mainly the Kano Two-Dimension Model and is supported with Importance-Performance Analysis(IPA) to explore the overall service quality of steel wires. This study takes the quality service phase of PZB as the foundation to design 20 items on the questionnaires which includes the basic steel wire physical properties and the wire services. To proceed the investigation by questionnaires, this study explores customer’s view about the current state of steel wires and analyses by IPA to find the key quality factor which should be improved immediately, and then categorizes the service items for steel wires by the feature of Kano Two-Dimension Model to find the property of each service item, and at the same time to calculate both the customer’s satisfaction index and dissatisfaction index for the quality of steel wire services, and further transfer both the customer’s satisfaction index and dissatisfaction index to weight-scale factor which will be applied to the Quality Function Deployment (QFD). After the quality engineering technology being established, the relationship between the technology and the service items will be explored. The manufacturer of steel wires must integrate each relative quality engineering technology to build the priority items for the improvement, look for the target of improvements, make adequate plans for the limited enterprise resources, apply the improvement method and administration strategy for appropriate production businesses to proceed efficient quality improvements and the promotions, gradually achieve higher customer satisfaction step by step.
