No. of bitstreams: 1 Ery Clovis Petry Jardim Junior_.pdf: 2380676 bytes, checksum: 3228458de9103b7053a9136b5d67eb55 (MD5) Previous issue date: 2018-02-28 / Nenhuma / Em diferentes subculturas de projeto, arquitetos, engenheiros e designers transitam entre dois caminhos para decidir quais serão os próximos passos a serem dados no design e projeto de produtos: o caminho do raciocínio e o caminho da intuição. Estes dois caminhos são fundamentados na teoria de Epstein (1999, 2003), denominada de teoria do processamento duplo de informações (CEST - Cognitive-Experiential Self-Theory of Personality). O caminho do raciocínio ou da racionalidade é o caminho das decisões baseadas na lógica das metodologias, métodos, ferramentas e processos que o designer utiliza para avançar na projetação na medida em que as informações sobre os problemas de design vão se estruturando. O caminho da intuição ou da experiencialidade é o das decisões baseadas nas experiências ou nas vivências pessoais que o designer acumulou em processos heurísticos, nos quais as metodologias, métodos, ferramentas e processos utilizados para dar um certo próximo passo na projetação não são claras o suficiente, pois não se dispõe de todas as informações sobre o problema de design e necessita-se ‘preencher as lacunas’ para avançar na projetação. Estes dois caminhos trilhados pelos arquitetos, engenheiros e designers no design e projeto de produtos serão analisados nesta dissertação, tendo como base os estudos sobre racionalidade limitada (Simon, 1969, 1996) e intuição limitada (Kahneman 2003), contando com o Inventário Racional- Experiencial (Rational-Experiential - REI, Pacini e Epstein, 1999, 2003) como instrumento de pesquisa. O estudo foi realizado na modalidade online com 156 participantes, revelando que na análise sobre formação os Engenheiros tendem a pensar de forma mais racional e tem mais confiança ao agirem assim, e, arquitetos e designers tendem a pensar de forma mais experiencial com mais capacidade de pensar com sentimentos e intuições. Na análise sobre tempo de experiência em design e projeto de produtos os designers tendem a pensar de forma mais racional e tem mais capacidade e confiança para agirem assim. Na análise sobre nível de formação os designers tendem a pensar tanto de forma racional, como experiencial e tem mais confiança e capacidade para agirem assim. / In different project subcultures, architects, engineers, and designers move between two paths to decide what are the next steps to be taken in product design and design: the path of reasoning and the path of intuition. These two paths are grounded in Epstein's theory (1999, 2003), called the CEST (Cognitive-Experiential Self-Theory of Personality). The path of reasoning or rationality is the path of decisions based on the logic of the methodologies, methods, tools and processes that the designer uses to advance the design as the information about design problems is structured. The path of intuition or experientiality is that of the decisions based on the experiences or personal experiences that the designer accumulated in heuristic processes, in which the methodologies, methods, tools and processes used to take a certain next step in the design are not clear enough, because all the information about the design problem is not available and it is necessary to 'fill in the gaps' to advance the design. These two paths, traced by architects, engineers and designers for the design and design of products, will be analyzed in this dissertation, based on studies of limited rationality (Simon, 1969, 1996) and limited intuition (Kahneman 2003) Rational- Experiential (Rational-Experiential - REI, Pacini and Epstein, 1999, 2003) as a research tool. The study was conducted online with 156 participants, revealing that in training analysis engineers tend to think more rationally and have more confidence in doing so, and, architects and designers tend to think in a more experiential way with more ability to think with feelings and intuition. In the analysis of experience time in product design and design the designers tend to think more rationally and have more ability and confidence to do so. In the analysis of the level of training, designers tend to think in a rational, experiential way and have more confidence and ability to act in this way.

Interference mitigation techniques for 4G networks / Techniques de lutte contre l’interférence intercellulaire dans les réseaux de 4ème génération

Jaramillo Ramirez, Daniel 27 January 2014 (has links)
Les communications sans fils sont devenues un outil fondamental pour les sociétés modernes. Les réseaux cellulaires sont le moyen préféré pour l’accès à Internet. L’augmentation de la capacité du réseau est étroitement liée au problème des interférences. Les réseaux coopératifs ont été largement étudiés dans les années récentes. Cette thèse porte sur deux techniques de coopération dans la voie descendante :La première partie étudie les effets de quantification et délais sur les informations de retour nécessaires pour la mise en opération des différentes techniques d’émission coordonnée, connues sous le nom de CoMP (Coordinated Multipoint Transmission). Cette technique qui promet des augmentations importantes sur la capacité du réseau en conditions idéales, or ses vrais résultats sous le feedback limité doivent être encore décrits de manière analytique. En particulier, pour les modes d’émission connus comme JT (Joint Transmission) et CBF (Coordinated Beamforming), des expressions analytiques ont été déduites pour calculer la capacité du réseau et la probabilité de succès de transmission.Finalement une nouvelle technique de coopération de réseau pour les récepteurs avancés du type SIC (Successive Interference Cancellation) est présentée. La condition mathématique qui garantit des gains de capacité grâce à l’utilisation des récepteurs SIC est obtenue. Pour en profiter, une méthode de coopération est nécessaire pour assurer une adaptation de lien adéquate pour que l’interférence soit décodable et le débit somme soit supérieur à celui atteint avec des récepteurs traditionnels. Cette technique montre des gains importants de capacité pour des utilisateurs en bordure de cellule. / Wireless communications have become a fundamental feature of any modern society. In particular, cellular networks are essential for societal welfare but the increasing demand for data traffic set enormous scientific challenges. Increasing the network capacity is closely related to the problem of interference mitigation. In this regard, network cooperation has been studied in recent years and several different techniques have been proposed. In the first part, different transmission techniques commonly referred to as Coordinated Multi-Point Transmission (CoMP), are studied under the effect of feedback quantization and delay, unequal pathloss and other-cell interference (OCI). An analytical framework is provided, which yields closed-form expressions to calculate the ergodic throughput and outage probabilities of Coordinated Beamforming (CBF) and Joint Transmission (JT). The results indicate the optimal configuration for a system using CoMP and provide guidelines and answers to key questions, such as how many transmitters to coordinate, how many antennas to use, how many users to serve, which SNR regime is more convenient, whether to apply CBF or prefer a more complex JT, etc. Second, a new coordination technique at the receiver side is proposed to obtain sum-rate gains by means of Successive Interference Cancellation (SIC). The conditions that guarantee network capacity gains by means of SIC at the receiver are provided. To take advantage of these conditions, network coordination is needed to adapt the rates to be properly decoded at the different users involved. This technique is named Cooperative SIC and is shown to provide significant throughput gains for cell-edge users.

Transport sédimentaire sur rugosités immobiles : de l'hydrodynamique locale à la morphodynamique / Transport of sediment over coarse roughness elements : from local hydrodynamics to morphodynamics

Raus, David 19 June 2018 (has links)
Cette étude, en partenariat avec l'AFB (Agence Française pour la Biodiversité), a pour objectif de comprendre le devenir des sédiments qui ont été bloqués dans des barrages hydrauliques. Lors des « chasses » (lâchers massifs d’eau) réalisées pour assurer la continuité écologique des cours d'eau avec retenues, une certaine quantité de sédiments est relarguée en aval de la retenue, cessédiments sont ensuite transportés sur un fond de rugosités immobiles à différentes échelles(gravier, galets, rochers). L'objectif de cette thèse est donc d'étudier comment la présence de grains grossiers et immobiles peut avoir un effet sur les différentes échelles du transport de sédiment. Au travers de trois études expérimentales en canaux hydrauliques à surface libre, dans lesquelles les grains grossiers immobiles sont modélisés par une canopée d'hémisphères régulièrement espacés, différents impacts de la présence des rugosités immobiles sont mis en exergue. Une étude préliminaire a tout d'abord pour objectif de comprendre comment l'apparition d'une rugosité isolée dans du sédiment a pour effet de modifier les conditions d’hydrodynamique locale à l’amont de cette rugosité, en particulier par la mise en place d'un système de tourbillon(tourbillon en fer à cheval) pouvant accentuer le taux d'érosion locale. Ce tourbillon, très documenté pour des rugosités à géométrie simple, demeure très peu étudié dans le cas d'obstacle aux parois courbées de type grains de rivière. Cette étude montre alors que les dimensions et l'intensité du tourbillon en fer à cheval sont plus faibles dans le cas d'un obstacle aux parois inclinées et courbées que dans le cas d'un obstacle aux parois normales au fond, cephénomène étant expliqué par la facilité du fluide à contourner et l'obstacle, et donc la diminution du gradient de pression adverse à l'amont de l'obstacle, responsable du décollement de la couche limite incidente et de la formation du tourbillon en fer à cheval. Dans une seconde étude,l'hydrodynamique locale proche de sédiment placé dans un patch d'hémisphères est mesuré, pour différents niveaux de découvrement du patch et pour du sédiment collé au fond du canal. Il apparaît qu'en fonction du découvrement ($P = k/R$ avec $k$ la hauteur découverte d'une rugosité et $R$ sa hauteur totale), de forte variations locales de contrainte et de niveaux de turbulence au fond se mettent en place, le sédiment étant soumis à des sur-contraintesimportantes à l'arrière des rugosités pour $P = 20\%$, mais protégés pour des découvrements plus importants. Une analyse par quadrants montre alors que ce phénomène peut être expliqué par la capacité des événements turbulents instantanés de forte intensité à pénétrer entre les hémisphères pour atteindre le sédiment. Une troisième étude dans un canal aux dimensions plus importantes consiste à analyser la déstabilisation d’un lit sédimentaire initialement plat être couvrant totalement une canopée d’hémisphères immobiles. En début de la déstabilisation du lit,des dunes se forment et croissent, jusqu'à ce que leur volume devienne limité par l'apport initial de sédiment. Des zones érodées apparaissent alors entre ces dunes, dans lesquelles on observe du sédiment protégé entre les hémisphères immobiles. Il apparaît alors que cette protection est dépendante de la dimension des zones érodées. Sur les temps longs et après évacuation des dunes en aval du canal, l'effet de protection des hémisphères immobiles sur le sédiment est mis en avant, avec en particulier l'obtention d'une forte dépendance du taux d'érosion des grains en fonction du niveau de découvrement des hémisphères, un ralentissement soudain de l'érosionétant obtenu pour $P \sim 50 %. Ce changement de régime est expliqué en lien avec les résultats de l’étude précédente sur les groupes d’hémisphères. / This study is part of a project with the AFB (French Agency for Biodiversity), that aims to have abetter understanding of the remobilization of the sediment previously trapped in dams. After dambreaks, an amount of sediment is deposited downstream of the dam, this sediment being then setin motion on a bed of multi-scale immobile grains (gravels, rocks, boulders). The aim of this thesiswork is to study how coarse immobile grains can have an effect on the different scales of sedimenttransport. Thanks to three experimental studies in laboratory flumes, in which immobile coarsegrains are represented by a canopy of hemispheres, several effects of the roughness elements onsediment transport are emphasised. A preliminary study first aims to understand how theprotrusion of an isolated hemisphere impacts the local hydrodynamics upstream of thishemisphere, specifically through the horseshoe vortex developping near the roughness elementwall that can increases local grain entrainment rate. The horseshoe vortex, although deeplydocumented for simple roughness elements (cube, cylinder), remains poorly studied for roughnesselements with tilted or curved front wall like river coarse grains. This study shows that thedimensions and intensity of the horseshoe vortex are weaker for an obstacle with tilted wall thanfor an obstacle with bottom normal wall. This phenomenon is explained by the weaker adversepressure gradient developping upstream of the titlted wall, responsible for the boundary layerseparation and the horseshoe vortex formation. In a second study, the local hydrodynamics near aglued sediment bed placed in a patch of hemispherical roughness elements is studied, for severalprotrusion levels $P$ of the hemispheres (where $P = k/R$, with $k$ the height of the hemisphereprotruding over the sediment, and $R$ the total height of the hemisphere). It is shown that,depending on the protrusion of the hemispheres, strong local modifications of the near bedhydrodynamics can develop. For P = 20 %, zones of enhanced shear stress appear downstreamof the roughness elements, while for P \ge 20 %, this enhanced shear stress zones vanishes andthe sediment bed is sheltered. A quadrant analysis then shows that this phenomenon is explainedby the abality of intense instantaneous events to reach the sediment bed. A third experimentalstudy aims to analyze the erosion of a flat sediment bed initially uniformely covering a canopy ofstaggered hemispheres. In the beginning of the experiment, dunes are forming on the sedimentbed, until their volume is limited by the supply-limited sediment condition. Eroded areas thenappear between dunes, in which sediment is protected between the immobile hemispheres. Theanalyze shows that this protection is strongly dependant on the dimensions of the eroded areas.After dunes migrated downstream of the canal, the sheltering effect of the hemispheres isemphasised by measuring the erosion rate of the bed. It appears that the erosion rate is heavilydependant on the level of protrusion of the hemispheres, the erosion suddenly getting weaker forP \sim 50 %. This abrupt change of erosion regime is explained using the results of the previousstudy on local hydrodynamics in a patch of hemispheres.

A (des)naturalização da pessoa jurídica: subjetividade, titularidade e atividade / The (de)naturalization of legal entity: subjectivity, legal capacity and activity

Sergio Marcos Carvalho de Ávila Negri 03 May 2011 (has links)
O presente trabalho, a partir da revisão do conceito de personificação, pretende investigar como se desenvolve o processo de naturalização da pessoa jurídica e os eventuais prejuízos decorrentes para a tutela do ser humano nas organizações sociais e para a descrição do fenômeno empresarial. Sob o prisma da filosofia da linguagem, realiza-se uma revisão bibliográfica sobre a utilização do termo pessoa jurídica no discurso do Direito, destacando, principalmente, a desconstrução promovida pelo chamado nominalismo. São, ainda, propostos critérios para a identificação da naturalização, a partir de uma gradação que procura segregar os diversos grupos de casos que lhe são correlatos. A tese foi estruturada em três etapas: subjetividade, titularidade e atividade. Ao cotejar a pessoa natural com a pessoa jurídica, em cada um desses planos, espera-se revelar a assimetria de razões que separam a personificação do ser humano daquela presente nas sociedades, associações e fundações. Do questionamento do individualismo metodológico presente na noção de pessoa jurídica resulta a reconstrução do próprio sistema analítico de conceitos do discurso jurídico, com a revisão das ideias de imputação, relação jurídica, titularidade e autonomia patrimonial. / This work, from a review of the concept of incorporation, aims to investigate how the naturalization process of legal entity develops and any losses incurred for the protection of human being in organizations and for description the phenomenon of the Firm. From the perspective of philosophy of language, this thesis reviews the literature concerning to the use of the term legal person in the discourse of corporate law, especially highlighting the deconstruction promoted by so-called nominalism. They are also proposed criteria for the identification of naturalization, with a gradation that seeks to segregate the different groups of cases that are related to this process.The thesis was structured in three stages: subjectivity, legal capacity and activity. By confronting the human being with legal entity, in each of these plans, it expects to demonstrate the specificity of the process of incorporation, which prevents any comparison with real person. The revision of methodological individualism in this idea of legal personality results in the reconstruction of the concepts of imputation, legal relationship, legal capacity and limited liability.

Přechod léčiv s obsahem pseudoefedrinu do skupiny OTC s omezením. / Switching medicines containing pseudoephedrine in OTC group limited

Koníčková, Veronika January 2011 (has links)
Goals: Prepare a case study on the transition to the new OTC medicines groups with restrictions. To evaluate the positives and negatives, which brought the introduction of the group - with OTC restrictions. Pick up generally applicable principles and specify non-functional parts of the system. Method: For data processing method was applied theoretical research. Literature was searched in the database of the Czech National Library - Klementinum, WHO database, TRIBUNE and interfaces of News portals. The instrumental case study was processed for a detailed insight into the issues. The case study is also based on the analysis of the legal framework of the Czech Republic. The documents provided by SÚKL are used for financial analysis. As another method the stakeholder analysis was used - analysis of opinions of people involved in the drug policy. Results: The case study shows that switching medicines containing PSE to the limited group of OTC to prevent producers of drugs buing drugs in Czech pharmacies, but it did not reduce the amount of drugs produced in the country. Producers started to import precursors from abroad. The whole new system established in 2009 was correct in principle, but failed in practice. State Institute for Drug Control or other stakeholders in drug policy have not been able to resolve the ensuing complications.
