Na teoria quântica é usual se referir a probabilidade de encontrar uma partícula entre as posições x e x + dx no instante t, embora a teoria não forneça quando ocorre a detecção. Nos primórdios da teoria, Pauli apresentou um argumento refutando a ideia de introduzir um operador que descreva a probabilidade do instante em que ocorre a detecção. Mais tarde, Page e Wootters, motivados pelo fato de não se observar autoestados de superposição de energia, apresentaram um formalismo quântico não-relativista num espaço estendido em que espaço e tempo desempenham papéis equivalentes, sendo consistente com as indagações feitas por Pauli. Isso leva a uma descrição dada pela probabilidade condicional de encontrar uma partícula entre x e x + dx em relação ao tempo [t, t + dt] dado por outra partícula, chamada de partícula relógio. Essa dissertação consiste de uma revisão da proposta de Page e Wootters para abordar o problema do tempo na mecânica quântica bem como de uma análise detalhada desta utilizando de ferramentas recentes introduzidas na área de informação quântica para o tratamento de simetrias em física.
In quantum theory it is usual one refers to the probability of finding a particle between the positions x and x + dx at time t, although the theory does not provide when detection occurs. In the primordies of the theory, Pauli presented an argument refuting the idea of introducing an operator describing the probability of the instant in which the detection occurs. Later, Page and Wootters, motivated by the fact that one is not able to observe energy eigenstates superposition, presented a non-relativistic quantum formalism in an extended space in which space and time play equivalent roles, being consistent with Pauli´s inquiries. This leads to a description given by the conditional probability of finding a particle between x and x + dx in respect to the time [t, t + dt] given by another particle, called the clock particle. This dissertation consists in a review of the Page and Wootters proposal to address the time problem in quantum mechanics as well as a detailed analysis of this using recent tools introduced in the area of quantum information for the treatment of symmetries in physics.

Resumo: Este estudo avaliou a metodologia dos isótopos estáveis de carbono como um método alternativo e mais apurado para determinar o tempo de trânsito gastrointestinal (TTG) em juvenis de pacu (Piaractus mesopotamicus), em comparação ao método convencional com a adição de marcadores de contraste na dieta. Foram utilizados 320 juvenis estocados em 32 tanques, que receberam duas dietas, uma baseada em ingredientes do ciclo fotossintético C3 e outra baseada em ingredientes de origem C4, ambas contendo marcador inerte óxido de titânio (para tornar as fezes esbranquiçadas) e cultivados em duas temperaturas de água, 25 e 29 ºC. Após 40 dias, as dietas foram trocadas: os animais que recebiam a dieta C3 passaram a receber a dieta C4 (C3/C4) e vice-versa (C4/C3). As novas dietas continham marcador inerte óxido de crômio, para determinar o TTG através das duas metodologias: a convencional que utiliza marcadores de contraste e outra, sugerida neste estudo, por meio dos isótopos estáveis de carbono. As fezes foram coletadas por extrusão manual durante um período de 30 horas após a troca das dietas. Na metodologia dos marcadores inertes, as fezes receberam notas de 0; 0,25; 0,50; 0,75 e 1,00 de acordo com a intensidade da mudança de coloração de branco para verde escuro. Na metodologia dos isótopos estáveis, as fezes foram analisadas para determinação da mudança da razão isotópica de carbono-13.

Abstract: This study evaluated the stable carbon isotopes as an alternative and more accurate methodology to determine the gastrointestinal transit time (GTT) in pacu (Piaractus mesopotamicus) compared with the conventional method with addition contrast markers in the diet. 320 juveniles were equally distributed in 32 tanks. These tanks were divided in two feedings groups containing titanium oxide as inert marker in their diets (to induce white feces). One group was fed with diets based on 03 photosynthetic cycle plants, while the other group was fed with diets based on 04 plants. Both feeding treatments were subdivided in two water temperatures cultures, 25 and 29 °C. After 40 days we changed the diets: animals that had been fed with 03 diets were then fed with 04 diets (03/04) and vice versa (04/03). The new diets had chromium oxide as inert marker to determine the GTT through both methodologies: the conventional one which uses contrast markers, and other, suggested in this study, using stable carbon isotopes. Feces were collected by manual extrusion during 30 hours period after diet change. For the inert markers methodology the feces were graded in 0, 0.25, 0.50, 0.75 and 1.00 accordingly to the intensity of the color pattern that ranges from white to dark green. For the stable isotopes methodology the feces were analyzed to determine the change in the isotopic ratio of carbon-13. We conducted a completely randomized experimental design with four treatments and eight replicates. Data obtained from performance were subjected to analysis of variance (ANOVA) followed by Tukey test (a = 0.05), when significant differences were detected. GTT data, of both methodologies, were analyzed accordingly to the Boltzmann sigmoidal regression model. The average of water temperatures... (Complete abstract click electronic access below)

L'accès permanent et sécurisé aux ressources, données et services proposés par une entreprise est devenu au fil des années un point critique dans la stratégie de mise en place de l'infrastructure réseau. Situé à l'entrée du réseau interne et chargé de faire respecter la politique de sécurité mise en place par l'administrateur, le pare-feu est bien souvent l'unique point d'accès par lequel transitent toutes les connexions avec l'extérieur, et représente de ce fait un unique point de défaillance potentiel (« single point-of-failure »). Afin de pallier cette faiblesse, plusieurs solutions de redondances de pare-feux ont vu le jour. Ce document a pour but de présenter, d'évaluer et de comparer deux solutions reconnues du monde du logiciel libre : les conntrack-tools sous Linux, et pfsync/CARP sous OpenBSD. On présente également une nouvelle implémentation de canaux d'échanges d'états de connexions entre les pare-feux sous Linux, basé sur le protocole TIPC.

Mon sujet de thèse en arts plastiques s’appuie sur une pratique personnelle du carnet que j'entretiens depuis la fin de mes études à l'université de Rennes 2. Carnet de voyage, carnet de parcours, carnet de vie, carnet d’expériences où se mêlent et s'entremêlent des langages de différentes natures : écrit, graphique, collagiste, photographique… Je souhaite donner à cette production une dimension réflexive et spéculative qui permette de mieux en saisir les modalités plastiques et iconiques et d'en comprendre les enjeux. Pour ce, j’examinerai les travaux réalisés à la lumière des sciences humaines (sociologie, anthropologie, géographie, etc.) et des sciences de l’art (histoire de l’art, esthétique, poïétique ). De même je les confronterai à un corpus d’œuvres-références historiques, contemporaines et actuelles afin d’en dégager les affinités et spécificités. Qu'est ce que le carnet engage ? La perception du moment, la volonté de comprendre, les liens avec le patrimoine artistique et culturel, le rapport au monde contemporain jusque dans ses éléments les plus ténus ? D'autres choses plus complexes telles la construction de soi, le développement d'une identité graphique ou plastique ? Les tentatives de réponses à ces questions permettront d’envisager une ouverture de cette pratique de carnettiste vers l’univers scolaire. En tant qu'inspecteur pédagogique régional d'arts plastiques (antérieurement j’étais enseignante de collèges et lycées dans cette discipline), je m'interroge sur les modalités pédagogiques de mise en place d'un parcours artistique et culturel de l'élève par le biais du carnet ou du cahier devenu carnet. Ce dernier, dans les mains d'un public jeune, ne serait-il pas un moyen de s'approprier de manière constructive, ludique et imagée l'univers artistique à travers le prisme scolaire ? Au-delà de l'investissement artistique et théorique personnel, cette thèse pourrait avoir une portée pragmatique et connaître des applications expérimentales en milieu scolaire au sens large, c'est-à-dire de l'école à l'université
My subject of thesis in visual arts is based on a personal practice of the notebook that I have been carrying on since the end of my studies at the university of Rennes 2. These sketchbooks trace travel, career and life experiments by mixing and intermingling different languages: writing, graphics, collages and photography. I wish to infuse a reflexive and speculative dimension to this production in order to catch its plastic and iconic methods and to understand its challenges. To achieve this, I will study works in the light of social sciences (sociology, anthropology, geography, etc) and sciences of Arts (art history, aesthetics, poetics). In the same way I will confront them with a corpus of historical, contemporary and current work-references in order to reveal their affinities and specificities. What does the notebook imply? The perception of the present moment, the will to understand, the links with the artistic and cultural heritage, the relationship to the contemporary world down to its thinnest elements? Other more complex things such as self-construction, development of a graphic or plastic identity? The attempt to answer these questions enables a possible opening of this practice of carnettist towards the world of school. As a regional school Inspector for Visual Arts and a former teacher in lower and upper secondary school for that discipline, I wonder about teaching methods to provide pupils with a cultural and artistic background by using notebooks or workbook that became notebooks. Could it be the tool for young people to acquire in a constructive, playful and colourful way to enhance their approach to the artistic universe through the scholar prism? Beyond the artistic and theoretical personal involvement, this thesis could find a pragmatic application and an experimental implementation at school in a broad sense, i.e. from school to university

The involvement of Clostridium estertheticum as agents of deterioration of chilled beef packaged under vacuum from slaughterhouse brazilian, has been reported since 2007. Once detected, and presents the main sources of contamination in slaughter establishments, there was the need to advance the search for new knowledge about this Clostridia, however, the classical microbiological methods for their detection are considered difficult to implement because they require hard work and take a long time. PCR can be a quick and efficient detection of clostridia incriminated in the deterioration of beef chilled vacuum packaged and refrigerated environments slaughterhouses, without isolation of pure cultures. The objective of this study was to develop a test for realtime PCR for detection of Clostridium estertheticum in bovine meat and environments of slaughterhouse brazilian, as well as the molecular identification of isolates of Clostridium estertheticum by means of AFLP and RFLP techniques - PCR. The analytical results were compared with conventional PCR and confirmed by isolation. The Real-Time PCR assay for detection of Clostridium estertheticum in bovine meat and environments of slaughterhouse brazilian, was efficient. Evidence for the presence and distribution of C. estertheticum the sources studied and the technique of RT-PCR provided the highest percentage of positive samples from slaughterhouses that refrigerators Conventional PCR, and this is confirmed by isolation, which has become an important alternative for the detection of C. estertheticum in bovine meat and environments of slaughterhouse without isolation. The isolates used showed general similarity of 42.4%, suggesting high genetic diversity. In addition, the isolates obtained from samples of ambient and refrigerated meat tufted not show significant similarity, greater than 80%, used with any typical strain. The similarity found between the isolates may be indicative of possible similarity between those from meats and puffed from between those environments and equipment. The study revealed that additional steps necessary x for the characterization of Brazilian isolates, especially sequencing of other regions of the DNA so as to determine their taxonomic position.
O envolvimento de Clostridium estertheticum como agente de deterioração de carnes bovinas refrigeradas embaladas a vácuo provenientes de ambientes de frigoríficos no Brasil, vem sendo relatado desde 2007. Uma vez detectados, bem como apontadas as principais fontes de contaminação nos estabelecimentos de abate, surgiu à necessidade de avançar na busca de novos conhecimentos sobre esses clostrídios. No entanto, os métodos microbiológicos clássicos para sua detecção são considerados de difícil execução, pois exigem muito trabalho e demandam muito tempo. A PCR pode ser uma alternativa rápida e eficiente para detecção de clostrídios incriminados na deterioração de carnes bovinas refrigeradas embaladas a vácuo e ambientes de matadouros-frigoríficos, sem a necessidade de isolamento em culturas puras. Objetivou-se com o presente estudo desenvolver um ensaio de PCR em Tempo Real para detecção de Clostridium estertheticum em carnes bovinas e superfícies diversas de matadouros-frigoríficos brasileiros, assim como a identificação molecular de isolados de Clostridium estertheticum, por meio das técnicas RFLP e AFLP – PCR. Os resultados analíticos foram comparados com PCR Convencional e confirmados pelo isolamento. O ensaio PCR em Tempo Real desenvolvido para detecção de Clostridium estertheticum em carnes bovinas e superfícies diversas de matadouros-frigoríficos brasileiros, mostrou-se eficiente. Evidencia-se a presença e disseminação de C. estertheticum nas fontes estudadas e a técnica de PCR em Tempo Real proporcionou maior percentual de positividade para amostras de matadouros- frigoríficos que a técnica de PCR Convencional, sendo este confirmado pelo isolamento, o que demonstra ser uma alternativa importante na detecção de C. estertheticum de carnes bovinas e superfícies diversas de matadouros-frigoríficos sem a necessidade de isolamento. Os isolados utilizados revelaram similaridade geral de 42,4%, sugerindo alta diversidade genética. Além viii disso, os isolados obtidos a partir de amostras de ambientes frigoríficos e carnes tufadas não apresentaram similaridade significativa, maior que 80%, com nenhuma cepa padrão utilizada. A similaridade encontrada entre os isolados pode ser indicativa de possível semelhança entre aqueles provenientes de carnes tufadas e entre aqueles provenientes de ambientes e equipamentos. O estudo mostrou serem necessárias etapas complementares de caracterização dos isolados brasileiros, principalmente sequenciamento de outras regiões do DNA para assim determinar sua posição taxonômica.

La germination est un processus clé qui conditionne la régénération des plantes dans leur milieu ainsi que leur distribution. Connaître les conditions thermique et hydrique qui permettent aux plantes de germer est un préalable nécessaire à l’identification des menaces qui pèsent sur elles et tout particulièrement dans un contexte de changement climatique. Les modèles en temps thermique et temps hydrique permettent de prédire la phénologie de germination sur le terrain en fonction des conditions climatiques dans l’environnement de la graine dépassant des valeurs seuil de température et de potentiel hydrique de base, Tb et Ψb (i.e. respectivement la température minimale et le potentiel hydrique minimum permettant la germination).Dans ce travail de thèse, il est donc question d’étudier l’écophysiologie de la germination à l’aide de ces modèles à deux échelles taxonomiques : (i) celle des plantes à graines et (ii) à l’échelle du genre Silene de la région PACA. Dans les deux cas le but est d’évaluer les contraintes évolutives des traits de réponse au climat de la germination ainsi que leurs liens avec les contraintes morphologiques et phénologiques des plantesLes résultats de cette thèse montrent un fort signal phylogénétique des traits de germination de la température de base et une plus grande labilité pour le potentiel hydrique de base quelle que soit l’échelle taxonomique considérée. En revanche, les liens avec les traits des plantes, tels que la masse des graines, sont plus variables et dépendent à la fois de l’origine biogéographique et de la longévité des espèces
Germination is a key process in plant reproduction, a critical and irreversible phase conditioning the regeneration and distribution of plants. Understanding how temperature and water act on germination, is major step prior to identify risks plants may undergo under warming climate. Thermal time and hydrotime modelling of germination are useful tools to predict germination in the field as a function of climatic conditions above threshold value of temperature and water potential (respectively base temperature, Tb, and base water potential, Ψb) in a seed’s environment. This PhD thesis aimed at studying germination ecophysiology at two contrasted taxonomic scales: (i) for all seed plants and (ii) at the restricted level of the genus Silene in the Provence Alpes Côte d’Azur region. In both cases the objective was to evaluate evolutionary implications of the germination traits, Tb and Ψb and their link with plant morphological and phenological constraints. This work is structured in three parts : (I) Temperature but not moisture response of germination shows phylogenetic contraints while both interact with seed mass and life span ; (II) Germination ecophysiology in the Silene genus : thermal time and hydrotime models ; (III) Comparative ecology of Silene germination : relation with plant traits and climate.The mains results of this work show strong evidences of phylogenetic signal in base temperature and greater lability for base water potential at both taxonomic scales. The links with plant traits such as seed mass depend on biogeographical origins and life span

A presente dissertação pretende dar a conhecer os resultados da pesquisa desenvolvida sobre a pluriatividade na agricultura. Neste trabalho fiz a caracterização agrícola concelhia e avaliei no espaço local o fenómeno desta nova forma de ruralidade. Para o efeito pretendi contribuir para o entendimento, num quadro regional, das representações sociais dos atores locais face à pluriatividade na agricultura - o caso particular do concelho de Grândola. Na elaboração da minha dissertação de Mestrado, utilizei as quatro técnicas de recolha de dados mais frequentes na investigação sociológica: a observação direta, a pesquisa documental, o inquérito por questionário e a entrevista. Após o tratamento e análise dos dados obtidos, concluí que: - As receitas das explorações agrícolas são insuficientes para satisfazer as necessidades dos agricultores e suas famílias; - Os agricultores locais, tornaram-se minoritários no universo em estudo, diversificando as suas áreas de atividade; - O espaço rural para além da produção de cereais e outras culturas apresenta-se agora disponível para funções diversificadas (predominantemente no domínio das atividades turísticas); - A pluriatividade na agricultura assume uma importância vital, no desenvolvimento regional; - A PAC, ao ser introduzida, criou nos agricultores um conjunto de expectativas, as quais não se vieram a concretizar na sua globalidade; - O mundo rural neste concelho apresenta-se muito debilitado, tendo os agricultores consciência da necessidade de praticarem outras atividades além da agricultura. ***/Abstract - The current dissertation aims to let know the results of the research developed on multi-activity on agriculture. In this work l has made the district's agricultural characterization and I have locally evaluated the phenomena of a new form of rurality. I have helped for the understanding, in a local basis, of the social representations of the local intervenients respecting the multi-activity in agriculture - on the specific case of Grândola's district. On the making of my Master degree thesis, l has used four common techniques on the data gathering in sociology: direct observation, documental research, the filing of questionnaires and interview. After the analysis of the results, l have concluded that: - The income of agricultural exploitation is not enough to satisfy the needs of farmers and their families - Local farmers have become a minority in society, varying their income source - Besides the production of cereals and other cultivations, the rural space is now available for different functions (mainly touristic activities) - The multi-activity in agriculture assumes a vital importance on local development - By the introduction of the CAP, local farmers have created expectations that have not generally been satisfied - ln this district, the rural world is quite feeble, creating the need to practise other activities besides agriculture.

Les sociologues s’accordent pour constater l’émergence de nouveaux rapports au temps, mais débattent des marges de manœuvre différenciées dont disposent les individus face à ces phénomènes. L’hypothèse que la vitesse de déplacement puisse être un levier est confortée par les études montrant que nos sociétés ont maîtrisé l’espace-temps grâce à l’amélioration des transports d’information et de marchandises. Cependant, peu de travaux empiriques abordent le sujet à l’échelle de l’individu. Cette thèse, qui repose sur une combinaison de méthodes qualitatives et quantitatives, a pour objectif de compléter ces recherches à travers l’étude des modes de transport utilisés et des pratiques spatiales quotidiennes en Île-de-France. Cette approche micro-sociale montre que l’augmentation du nombre et de la durée des activités hors du domicile n’est pas corrélée à une hausse des vitesses, mais à une diminution des distances parcourues pour se rendre à certaines activités. Ceci s’explique par les logiques de localisation des activités des individus. Pour celles auxquelles ils accordent de la valeur, ils maximisent la qualité de la destination, ce qui passe par l’utilisation de modes motorisés rapides. Pour les activités secondaires, ils minimisent leur temps de trajet en les localisant à proximité d’activités structurantes, ce qui induit l’usage de modes plus lents. Comme l’articulation entre ces deux logiques est plus aisée dans Paris qu’en banlieue, l’adoption d’un rythme de vie plus élevé et d’une planification plus souple y est facilitée. Plus que l’accès à la vitesse, ce sont les territoires de résidence qui induisent des disparités dans les marges de manœuvre face au temps
Times studies agree on the fact that our society is currently undergoing changes in terms of pace of life, but debates arise as to the uniformity of such changes within the population and individuals’ scope of action in the face of said phenomena. Given that society as a whole mastered time and space through the rise of transport speed, one is tempted to assume that it is also the case on the individual level. However, few empirical studies have taken it upon themselves to analyze the impact of speed in daily mobility on individuals’ pace of life. Using a combination of statistical analysis and in-depth interviews, this thesis aims at providing supplementary insight into the topic by analyzing transport modes and mobility patterns of inhabitants of the Greater Paris region. Through this micro-social analysis, we show that the more out-of-home activities people do, the lower their average speed in the course of a day is, whilst the average distance to a destination also decreases. This can be explained by the way they choose their destinations. For activities which are meaningful to them, they maximize the utility of their destination by using fast transport modes. For ancillary activities, they minimize travel time by locating them in the direct vicinity of their high-value activities, which prompts the use of slower modes. Finally, we show that the combination of these two rationales is easier in the center than in the suburbs, thus facilitating a high pace of life and more improvised schedules in the former. Hence, more than access to speed, it is residential location which induces disparities between people in their ability to deal with time demands

Cette thèse se propose d’aborder la question de la causalité dans une perspective formelle inspirée du cadre de la SDRT (Segmented Discourse Representation Theory). Elle prête en particulier attention aux expressions paratactiques de la relation de causalité. Cette approche nous paraît intéressante et féconde par l’approche formaliste qu’elle met en œuvre, son objet étant particulièrement labile. L’analyse, dans ce travail, est notamment centrée sur l’expression linguistique des relations causales. L’approche adoptée, pour mener à bien les traitements, est dans une large mesure de nature sémantico-pragmatique. Bien que le fonctionnement de la causalité marquée linguistiquement, notamment au moyen de parce que, soit particulièrement documenté dans le paysage scientifique (Moeschler 2003, Rossari 2004, Knott 1996, etc), les enchaînements non marqués (paratactiques) semblent être peu étudiés dans les recherches linguistiques. Ce qui constitue en quelque sorte la motivation principale qui a impulsé la mise en œuvre de cette monographie. Cette étude pourrait donc se situer à l’interface entre linguistique théorique et linguistique formelle. Les traitements qui y sont effectués prennent appui dans une large part sur le corpus EXPLICADIS (Explication et Argumentation en Discours). Le choix de cette ressource pourrait se justifier de la sorte : ce corpus permet de rendre compte des relations causales selon une approche sémasiologique consistant à s’appuyer presque exclusivement sur la relation elle-même sans tenir compte de ses marqueurs linguistiques. Par ailleurs, nous aborderons, dans cette recherche, la question de la Causation. Sur ce plan, le traitement argumental (« Le spectre argumental ») des verbes dits causatifs (causer, provoquer, déclencher, etc.) nous permettrait de noter que les arguments de ce type particulier de prédicats admettraient une interprétation propositionnelle. L’hypothèse de départ est que la causation, ainsi conçue, semble représenter une relation inter-propositionnelle implicite ou plus simplement sous-jacente. Bien plus, nous nous intéresserons à la dichotomie causalité / agentivité
This thesis proposes to address the question of causality in a formal perspective inspired by the framework of SDRT (Segmented Discourse Representation Theory). In particular, she pays attention to paratactic expressions of the causal relationship. This approach seems interesting and fruitful to us by the formalistic approach that it implements, its object being particularly labile. The analysis in this work focuses on the linguistic expression of causal relationships. The approach adopted to carry out treatments is to a large extent semantico-pragmatic. Although the functioning of linguistically marked causality, especially by means of because, is particularly documented in the scientific landscape (Moeschler 2003, Rossari 2004, Knott 1996, etc.), untagged sequences (paratactic) seem to be little studied in the linguistic research. This is in a way the main motivation that drove the implementation of this monograph. This study could therefore be situated at the interface between theoretical linguistics and formal linguistics. The treatments that are carried out rely largely on the EXPLICADIS corpus (Explanation and Speech argumentation). The choice of this resource could be justified in this way: this corpus makes it possible to account for causal relations according to a semasiological approach of relying almost exclusively on the relation itself without taking into account its linguistic markers.Moreover, we will address, in this research, the question of the Causation. In this respect, the argumental treatment ("the speculative spectrum") of so-called causative verbs (cause, provoke, trigger, etc.) would allow us to note that the arguments of this particular type of predicate would admit a propositional interpretation. The initial hypothesis is that the causation, thus conceived, seems to represent an implicit or more simply underlying inter-propositional relation. Moreover, we will focus on the causality / agency dichotomy

The placement of an unconformable surface within a stratal succession affects the interpreted thickness of units and sequences in contact with that surface. Unit thickness influences the interpretation of basin subsidence, paleotopography, diagenesis, and depositional style. Accurate placement of an unconformity results in true formational thicknesses for formations associated with that unconformity. True thicknesses aid in producing more precise surface to subsurface correlations, isopach maps, and paleogeographic maps. An unconformity may be difficult to identify in the stratal succession due to similar rocks above and below the unconformity and the presence of multiple candidate surfaces. Using statistical discriminant analysis of XRF data, formations bounding an unconformity can be discriminated by elemental composition which results in delineation of the associated unconformity. This discrimination is possible even for rocks that do not have significant differences in provenance if they have experienced distinct diagenetic histories. Elemental differences can be explained by quantity and type of cement. Three discriminant models were created. These models were tested with samples from three formations of similar facies, appearance, and provenance that are all associated with the same regional unconformity. All data, regardless of location, facies, or tectonic feature were used to create the first model. This model achieved moderate success by correctly classifying 80% of known samples. In a second model, data were grouped by facies trends. Separating the data by facies resulted in 94% of known samples being correctly classified. This model was most useful for delineation of an unconformity and discrimination of formations. A third model based solely on location or local tectonic feature produced the best results statistically. 96% of known samples were classified correctly. This third model does not compare locations to each other, thus making it less robust. This last model contributes by adding detail to interpretations made with the facies trend model.

A pesar de que hi ha més de trenta anys d'investigació sobre els temps d'espera, poc es coneix sobre aquells que estan disposats a pagar més per evitar les esperes i sobre aquells que no ho estan, en el context dels parcs temàtics. La present tesi doctoral examina els factors interns i externs que influeixen en la decisió de compra del passi exprés en un entorn real. Variables com el dia de visita al parc, el mètode a través del qual van conèixer aquest tipus de passi, el nombre de persones del grup, la cultura, l'actitud cap al passi exprés, l'actitud cap als temps d'espera, l'experiència prèvia comprant aquests passis, les expectatives sobre l'espera, les percepcions sobre l'espera i la motivació de la visita al parc apareixen com a variables significatives que permeten caracteritzar els dos grups: els que estan disposats a adquirir el passi i els que no. D'aquesta manera, no tots els consumidors interpreten de la mateixa manera els temps d'espera i els sistemes per evitar-los, i per tant han de ser tractats diferent. Entendre com els consumidors actuen permet a les empreses repensar els sistemes de prioritat i les estratègies de màrqueting per gestionar l'espera.

La presente tesis examina los factores internos y externos que influyen en la decisión de compra del pase exprés en un entorno real. Variables como el día de visita al parque, el método a través del cual conocieron el pase exprés, el número de personas en el grupo, la cultura, la actitud hacia el pase exprés, la actitud hacia los tiempos de espera, la experiencia previa comprando pases exprés, las expectativas sobre la espera, las percepciones sobre la espera y la motivación de visita al parque aparecen como variables significativas que permiten caracterizar a ambos grupos. De esta manera, no todos los consumidores interpretan de la misma manera los tiempos de espera y los sistemas para evitarlas, y por tanto deben ser abordados de diferente manera. El entender cómo los consumidores actúan permite a las empresas repensar los sistemas prioritarios y las estrategias de marketing para gestionar la espera.
In spite of more than thirty years of research on waiting, little is known about those who are willing to pay extra to avoid waits and those who don’t in a theme park context. This thesis examines factors that influence on the purchase decision of an express pass in a natural setting. The logit model with both internal and external factors shows a better explanatory capacity to classify individuals over other models. Variables such as visit day, how customers find out about the express pass, number of people in the party, culture, attitude toward the express pass, attitude toward waiting times, prior experiences purchasing an express pass, prior experience visiting theme parks, expectation of average waiting time, perception of waits shorter than expected and visit motivation (thrill and leisure) appear as significant variables that allow to characterize both groups. In this manner, not all consumers interpret waiting times and the systems to avoid them in the same way and, consequently, they should be addressed in different ways. Understanding how customers act allow companies to rethink priority systems and marketing strategies to manage waits.

L'étude détaillée des paradoxes de la composition d'Henri Matisse, roman constitue le point de départ de la compréhension d'une oeuvre qui multiplie et brouille à la fois les points de repères de toute construction accomplie dans l'acte de lecture. La notion d'identité textuelle, plus ouverte sur le versant de la lecture et les perturbations de la démarche interprétative, sera introduite en remplacement de celle d'unité. Le livre affiche l'ambivalence de toute délimitation rigoureuse de l'objet textuel et de son contenu, et nous conduit à faire l'expérience d'une hétérogénéité dynamique. Le lecteur est alors contraint de s'interroger sur la pertinence des catégories traditionnelles de la poétique, comme celle de genre ou celle de fiction. L'analyse introduit la métaphore heuristique du cadre comme instrument de pensée d'une entreprise d'ouverture sur l'au-delà du texte, c'est-à-dire le visible, le monde, et permet de penser le projet comme une rééducation du regard qui appliquerait à la lecture la "leçon de Matisse". La démarche lène ainsi à une définition du réel en jeu dans le livre, et à l'approfondissement de la conception de la tâche "réaliste" de l'écrivain. Le livre invite à une lecture phénoménologique d'un espace où présentation et représentation sont inséparables. La démarche herméneutique d'Henri Matisse, roman, va alors de pair avec la création d'un espace livresque où s'établit une "relation critique" du lisible et du visible, du peintre et du poète, qui cherche à établir le lieu commun des "producteurs de signes"
The detailed study of the paradoxes in the composition of Henri Matisse, roman is the starting point in the understanding of a work that simultaneously multiplies and mixes the reference marks of the act of reading. The idea of textual identity shall be preferred to that of unity, as it allows a more open access to the reading process and the obstacles to interpretation. The book demonstrates the ambivalence of any rigorous limitation of the textual object and of its contents and leads us to experience its dynamic heterogeneity. The reader is thus obliged to reevaluate the relevance of the traditional categories of poetics, such as genre and fiction. The analysis introduces the frame as a heuristic metaphor for the opening of the text towards what is beyond the textual domain (the visible, the world) in order to consider Aragon'swork as a reeducation of the eye and the application of the " Lesson of Matisse " to reading. This leads to a redefinition ot the " real " within the book and to a deepened understanding of the writer's conception of " realism ". The book calls for a phenomenological reading of a space where presentation and representation are interdependent. The hermeneutic process of Henri Matisse, roman accompanies the creation of a book-space where a " critical relationship " is established (between reading and seeing, between the painter and the poet) that attempts to create the common ground between " sign producers "

O presente trabalho teve como objetivo avaliar a associação da expressão gênica e proteômica com a maciez da carne de bovinos da raça Nelore. A partir de uma população de 90 animais foram selecionados três grupos experimentais por meio da análise de força de cisalhamento (FC) e índice de fragmentação miofibrilar (MFI), sendo: carne moderadamente macia, carne moderadamente dura e carne muito dura. A expressão dos genes foi avaliada por meio da análise de PCR em tempo real e a análise proteômica foi realizada com base na separação de proteínas por meio da eletroforese bidimensional (2D-PAGE) e caracterizção por espectrometria de massas com ionização eletrospray (ESI-MS/MS). A expressão da isoforma da calpastatina (CAST2) mostrou-se up regulated (P<0,05) nos grupos de carne moderadamente dura e muito dura. Os genes HSP90AA1, DNAJA1 e HSPB1, os quais representam as proteínas de choque térmico Hsp90, Hsp40 e Hsp27, respectivamente, mostraram expressão down regulated (P<0,05) no grupo de carne moderadamente macia em relação ao grupo de carne muito dura. Na análise proteômica, a expressão do spot protéico das enzimas metabólicas TPI e PGM1, proteína estrutural PFN1 e aminiopeptidase LAP3 se mostraram up regulated (P<0,05) no grupo de carne moderadamente macia, enquanto que a expressão das proteínas estruturais (ACTA1, ACTB, ACTG1 e MLC1), estresse oxidativo (PRDX6, PRDX2, PRDX1 and PARK7), proteínas de choque térmico (HSP90AA1, HSP90AB1, HSPA1A, HSPA1B, HSPA1L, HSPD1 e HSPB1), e co-chaperonas e regulação celular (CD37, STIP1 e ARHGDIA) se mostraram down regulated (P>0,05) no mesmo grupo experimental. Estes resultados fornecem uma visão importante de novos possíveis marcadores biológicos atuantes no processo de amaciamento da carne, o que pode colaborar para melhor entender e gerar novas estratégias de seleção nos programas de melhoramento genético de bovinos Nelore.
The objective of this study was to evaluate the association of gene expression and proteomics with meat tenderness in Nellore cattle. From population of 90 animals three experimental groups were selected by shear force (SF) and/or myofibrillar fragmentation index (MFI): moderately tender meat, moderately tough meat and very tough meat. Gene expression was evaluated by real-time PCR and proteomics analysis was performed based on protein separation by two-dimensional gel electrophoresis (2D-PAGE) and characterisation by eletrospray ionisation mass spectrometry (ESI-MS/MS). Expression of the calpastatin isoform (CAST2) was up-regulated (P<0.05) in the moderately tough and very tough meat groups. Expression of the HSP90AA1, DNAJA1 and HSPB1 genes, wich represent the heat shock proteins Hsp90, Hsp40 and Hsp27, respectively, were down-regulated (P<0.05) in the moderately tender meat in relation to the very tough group. In the proteomics analysis, the expression of the protein spots of metabolism TPI1 and PGM1, structural protein PFN1, and aminopeptidase LAP3 were up regulated (P<0.05) in the moderately tender meat, while the expression of structural proteins (ACTA1, ACTB, ACTG1 and MLC1), oxidative stress (PRDX6, PRDX2, PRDX1 and PARK7), heat shock protein (HSP90AA1, HSP90AB1, HSPA1A, HSPA1B, HSPA1L, HSPD1 and HSPB1) and co-chaperones and cellular regulatory (CD37, STIP1 and ARHGDIA) were down regulated (P>0.05) in the same experimental group. The present results suggest an important view of possible new biological markers in the meat tenderization process, wich permit to unsderstand and generate new strategies for selection in Nellore cattle breeding programs.

La conception des circuits integres consiste a determiner des valeurs acceptables des parametres afin de satisfaire certains criteres de fonctionnement du circuit donne par sa topologie. Le probleme est reformule en un probleme non lineaire a plusieurs dimensions avec contraisntes. Les fonctions a minimiser et les contraintes dependent implicitement des parametres d'optimisation par les equations du circuit, ce qui exige une simulation complete pour obtenir l'evaluation de la fonction. Les methodes du gradient et hessienne ne conviennent pas. La methode du simplex de nelder et head adjointe a une methode de recherche globale des meilleurs points d'attraction a ete retenue. Toutefois, la dimension n doit rester inferieure a 10. On tente de resoudre le probleme d'un grand nombre de variables en le fractionnant: au lieu d'agir sur la totalite des variables, on effectue des minimisations successives sur des sous-ensembles. Des essais sur des fonctions tests comportant jusqu'a 100 variables sont satisfaisants. On obtient la proportionnalite du temps de calcul et du nombre des variables. Ces methodes ont ete interfacees avec le simulateur electrique spice-pac et appliquees a la caracterisation de modeles de transistors et a l'optimisation de circuits

En lutte sous-marine, des l'acquisition d'un signal en sortie d'une antenne sonar, la premiere question qui se pose est : <<<>le signal comporte-t-il de l'information ou ne s'agit-il que de bruit?<>>> cette question est determinante pour la securite de l'equipage et du batiment. Depuis peu, on s'interesse a la detection des bruits transitoires. Signaux brefs, emis lors de manoeuvres, ils sont souvent moins discrets que les bruits rayonnes classiques mais leur caractere fugitif les avait rendus jusque-la moins remarquables. Les methodes classiques de detection sont souvent mal adaptees a ce type de signaux. C'est pourquoi nous abordons d'autres methodes pour ameliorer cette detection. Des algorithmes utilisant les transformees temps-frequence et les ordres superieurs sont compares. A l'issue de cette etude, nous montrons l'interet d'une methode utilisant le calcul du bispectre. Ce dernier presente des caracteristiques remarquables que nous decrivons precisement. L'utilisation du detecteur bispectral nous amene a etudier en detail l'environnement reel dans lequel nous travaillons. Nous montrons notamment que le bruit de mer presente des caracteristiques proches de celles d'une gaussienne qui le differencie des transitoires a detecter. Enfin, notre souci etant de proposer un detecteur operationnel, nous avons mis au point la detection bispectrale en temps reel. Cela nous a amenes a faire des choix quant a la programmation du detecteur en terme, par exemple, de longueur de fenetres d'analyse lors de l'estimation du bispectre. Nous expliquons les difficultes rencontrees lors de l'implantation. Nous montrons comment elles ont ete resolues et presentons les performances de la methode et du programme.

Deux nouveaux dispositifs en optique integree ont ete developpes grace a la technologie de l'echange d'ions sur verre. Les dispositifs, bases sur le principe de detection par onde evanescente, ont ete utilises comme capteurs chimiques (detection de gaz explosifs et vapeurs de solvants) et comme capteurs biologiques (detection de certains antigenes). Nous avons developpe deux systemes de traitement electronique et numerique du signal qui exploitent les atouts du premier dispositif, l'interferometre a champ de mesure elargi. Un de ces systemes permet a l'experimentateur (qu'il soit opticien, chimiste ou biologiste) d'acceder, en temps reel, non seulement au dephasage optique dans les zones d'interaction, mais egalement au bilan d'intensite dans le systeme de mesure (absorption de la lumiere et perturbations de la source optique). L'autre systeme, base sur l'acquisition du signal optique par une barrette de photodetecteurs, permet d'elaborer un capteur compact, de haute precision, et adapte pour la production en serie. Ainsi nous avons par exemple mesure des concentrations de vapeur d'heptane jusqu'a 0,05%. La limite de detection peut potentiellement atteindre quelques ppm. Ces resultats correspondent a une precision de detection de l'indice optique de l'ordre de 10#-#6. Le second dispositif est un interferometre non resonant a ondes multiples, dispositif propose et elabore pour la premiere fois. La fonction de transfert phase - intensite de cet interferometre peut etre choisie selon l'application visee. Nous avons analyse theoriquement quatre configurations de l'interferometre, et nos modeles ont ete verifies experimentalement pour deux configurations

Le projet comprend la realisation d'un systeme de detection de rayons x pour des experiences de diffraction aupres d'une source de lumiere synchrotron. Deux cellules de detection ont ete realisees: la premiere est un detecteur 1d ayant une largeur utile de 200 mm. La localisation de la position est faite par une ligne a retard lc de 500 ns. En ce qui concerne la deuxieme, la fenetre de detection utile est de 100 mm 10 mm. La determination de la position sur la grande dimension se fait grace a une ligne a retard mixte rlc combinant la structure d'une ligne a retard classique et celle d'une division de charges. Cette ligne est issue de l'etude d'une methode de ponderation par retard realisee dans le cadre de ce travail. La localisation de la deuxieme coordonnee est realisee par une lecture parallele des fils d'anode. L'electronique de traitement du signal est commune aux deux detecteurs. En effet, les deux methodes de localisation utilisees requierent une mesure de temps rapide et precise. Aussi, un convertisseur de temps numerique a ete realise specialement pour ces systemes. Les performances de ce convertisseur permettent des acquisitions rapides (au dela du mhz) bien adaptees aux demandes des utilisateurs. Le systeme d'acquisition est base sur une carte au standard pc pilotee par un logiciel sous l'environnement windows

Le theme dominant de ce travail de these, est l'analyse du comportement des ouvrages sous sollicitations dynamiques par la methode des elements finis. Sur le plan rheologique, on presente deux nouvelles lois de comportement basees sur le formalisme des lois incrimentales non lineaires du second ordre dont la specificite est de n'utiliser qu'un nombre reduit de parametres constitutifs. La reponse de ces lois est etudiee pour differents chemins de sollicitation. L'une de ces deux lois appelee loi duale, presente l'originalite d'etre ecrite sous une forme directe, bien adaptee aux analyses par elements finis. Sur le plan numerique on presente de facon detaillee les avantages et inconvenients lies a l'utilisation d'elements lagrangiens de haute precision. On propose notamment une technique d'optimisation permettant de diagonaliser la matrice de masse de ce type d'element ainsi qu'une formulation analytique de la pulsation maximale afin de definir pour un maillage donne le pas de temps critique correspondant. On aborde egalement la modelisation des milieux semi-infinis a partir de deux approches distinctes : la methode des frontieres absorbantes et les techniques de superposition. L'ensemble de ces developpements est accompagne de nombreuses validations largement detaillees.

Cette these contribue a l'etude du controle actif de l'acoustique d'une salle en utilisant des systemes electroacoustiques. L'idee essentielle est de constituer des murs actifs par un assemblage de cellules elementaires afin de changer la repartition energetique d'une salle. Chaque cellule doit permettre de regler le niveau de retour du haut-parleur a une valeur desiree tout en controlant la stabilite du systeme. Un ensemble des cellules convenablement couplees pourra alors controler le coefficient de reflexion globale d'un mur actif. Par consequent, le temps de reverberation et les premieres reflexions d'une salle seront controles. Une structure d'une cellule elementaire du systeme de mur actif est proposee. Deux filtres adaptatifs sont introduits pour controler respectivement la stabilite et le niveau de retour d'une cellule du systeme. Les algorithmes de calcul des deux filtres adaptatifs sont presentes. Les principaux resultats theoriques sont illustres sur des simulations. Le probleme de l'organisation des cellules d'un systeme de mur actif en vue de reconstituer un champ sonore le plus naturel possible a ete aborde. Les resultats de simulation de deux types de murs (un mur actif et un vrai mur de meme dimension) ont ete compares. La faisabilite pratique est discutee. Une realisation temps reel d'une cellule a ete implantee sur une carte specialisee (tms 320c30). Les performances du prototype d'une cellule sont testees notamment en ce qui concerne la stabilite d'un couple microphone haut-parleur. Un calcul acoustique theorique sous des hypotheses simplificatrices est donne. Nous pouvons donc evaluer en fonction du nombre de cellules le temps de reverberation d'une salle a partir de caracteristiques mesurees dans cette salle. Enfin un premier prototype simplifie d'un mur actif est presente

Il existe plusieurs technologies pour les capteurs de position. Par exemple, les potentiomètres résistifs sont bon marché, mais leur durée de vie est limitée par l'usure du contact électrique. Quand la durée de vie est un paramètre important, l'utilisation de capteurs magnétiques sans contact est une alternative intéressante. Dans la première partie de la thèse, une étude des principaux capteurs magnétiques de position est faite. Leur principe de fonctionnement et leurs principales caractéristiques (avantages et défauts) sont analysés. La seconde partie de la thèse est consacrée à la recherche de nouvelles structures de capteurs. Après s'être imposé les contraintes nécessaires, pour le bon fonctionnement d'un capteur, une étude systématique a permis de trouver une nouvelle famille de capteurs. Celle-ci se caractérise par une réponse linéaire et une faible sensualité à la température et aux défauts de réalisation des pièces du circuit magnétique (aimants permanents, pièces polaires). La dernière partie de la thèse porte sur l'étude d'un nouveau capteur. Les résultats d'une modélisation par éléments finis et d'une modélisation analytique sont comparés à des résultats expérimentaux

Les travaux presentes dans ce memoire concernent l'etude de l'amplification parametrique en regime femtoseconde. Ils visent surtout son application au developpement de sources femtosecondes accordables dans le visible. Ils touchent egalement a l'utilisation d'un amplificateur parametrique optique en tant que porte ultrarapide amplificatrice pour realiser de l'imagerie en milieu diffusant. Lors de cette etude, nous avons construit une chaine laser femtoseconde basee sur des cristaux de saphir dope au titane. Cette chaine produisait des impulsions a 780 nm de 100 fs de duree et de plus de 1 mj d'energie a un taux de repetition de 20 hz. Elle nous a ainsi permis d'effectuer des etudes sur l'emission conique qui accompagne la generation d'un continuum de lumiere blanche en milieu solide. Une analyse de nos observations experimentales dans le contexte de theories physiques connues telles la generation raman, le melange a quatre ondes et l'effet cerenkov nous a amenes a conclure qu'aucune theorie ne permet actuellement de decrire ce phenomene. Nous avons ensuite construit un amplificateur parametrique optique afin de realiser une source coherente femtoseconde accordable dans le visible. Cette source delivre des impulsions subpicosecondes de plus de 4j et accordables de 470 nm a 700 nm. Nous avons compare ses performances a celles d'un amplificateur parametrique injecte par un continuum spectral. Cette deuxieme source avait l'avantage de produire des impulsions plus courtes (200 fs). En revanche, l'energie de ces impulsions etait moins elevee (1 j), moins stable, et leurs profils spatiaux etaient moins beaux. Enfin, en se servant d'un amplificateur parametrique, nous avons reussi a detecter une mire a travers 20 libres parcours moyens d'une solution aqueuse de microspheres de latex avec une resolution spatiale de l'ordre de 200 m. Nous avons ainsi demontre la possibilite d'utiliser l'amplification parametrique pour realiser de l'imagerie en milieu diffusant.

Ce travail concerne la caracterisation structurale et l'etude de l'interdiffusion dans les superreseaux contraints cdte/cdznte et cdte/hgte, elabores par epitaxie par jets moleculaires, au moyen de la double diffraction de rayons x. Les parametres structuraux (composition, epaisseur, etat de deformation) sont obtenus de facon precise en utilisant conjointement l'experience et la simulation en theorie cinematique. Les coefficients d'interdiffusion des couples cd/zn (400c) et cd/hg (200c) sont mesures par diffraction x. Ils permettent de calculer les profils de concentration des superreseaux en fonction de la temperature et du temps de recuit. Par extrapolation, nous precisons les conditions de croissance pour obtenir des interfaces raides, qui sont necessaires pour des dispositifs optoelectroniques performants

L'objectif des travaux décrits dans ce mémoire est de rechercher le lien entre les propriétés de recombinaisons dans les hétérostructures de type GaAs/AlAs et la structure de l'interface. L'observation de variations des énergies de confinement dans les puits quantiques directs GaAs/(al,ga)as lies aux choix des températures de croissance amène une interrogation sur la nature des processus qui entrainent l'introduction d'un désordre aux interfaces (ségrégation verticale ou démixtion d'alliage) et conduise à approfondir l'étude de puits quantiques à double barrière GaAs/AlAs/(al,ga)as ou les épaisseurs de couches d'AlAs et de GaAs sont réduites à quelques monocouches. Les études expérimentales (excitation de photoluminescence, photoluminescence résolue en temps, photoluminescence sous pression hydrostatique) associées à une modélisation en fonction enveloppe démontre la diversité des alignements des niveaux confines et apporte des informations sur la localisation des électrons dans une ou deux monocouches d'AlAs. Ces expériences expliquent les processus de transferts entre les niveaux associes aux minima xxy et xz ou de capture sur les donneurs ainsi que le phénomène de couplage entre les états de GaAs et x d'AlAs. L'existence d'un confinement latéral est démontrée lorsque ces mêmes structures sont élaborées sur surfaces vicinales. Dans ces conditions l'analyse des recombinaisons de structures ou la couche d'AlAs est réduite à une monocouche révèle l'action des fluctuations des largeurs de terrasse sur les propriétés de recombinaisons

Le but de cette these est d'etudier la stabilite d'un agregat de sodium vis-a-vis d'un exces de charge positive. Dans un premier temps, nous avons procede a la construction de l'experience. La source utilisee pour la formation des agregats est du type thermalisation gazeuse. Avec cette source, nous avons obtenu des agregats froids de quelques atomes jusqu'a environ un millier. Le spectrometre de masse a temps de vol construit pour l'experience utilise un systeme d'acceleration a deux etages type wiley-mclaren, mais avec une focalisation amelioree. Une resolution en masse superieure a 2000 est obtenue vers la masse 1100 uma, et les agregats de sodium monocharges ayant jusqu'a 700 atomes peuvent etre separes. Dans un deuxieme temps, nous avons etudie la production et la stabilite d'agregats de sodium multicharges. L'ionisation sequentielle d'agregats neutres par une impulsion laser permet d'obtenir des agregats multicharges chauds, c'est-a-dire evaporant des atomes. La charge maximale des agregats est limitee par l'energie des photons. L'interaction d'agregats neutres avec des ions montre la coexistence de deux processus d'ionisation: la capture a distance d'electrons par le champ coulombien de l'ion et l'emission statistique d'electrons suite a l'excitation electronique de l'agregat quand un ion le traverse. Lorsque la charge de l'ion augmente, le premier processus devient predominant. Ceci implique une diminution de la temperature des agregats multicharges obtenus qui se traduit experimentalement par une diminution de la taille critique. En conclusion, l'interaction d'agregats neutres avec des ions permet de produire des agregats multicharges, de charge, de taille et de temperature variables. Elle apparait comme une methode de choix pour l'etude de la fragmentation lorsque ces edifices sont instables

Dans une grande variété d'applications, les capteurs de position sont requéris pour contrôler un processus. Pour ce type de capteurs, il existe plusieurs, technologies: codeurs optiques, -potentiomètres électriques et capteurs magnétiques. Toutes ces technologies ont leur champs d'applications et aussi leur prix. Quand un faible prix et une production en très grande série sont requéris beaucoup de ces technologies de capteurs ne respectent ces conditions. Par exemple, le potentiomètre donne un signal bruité par le contact électrique glissant et a une faible durée de vie. Par contre, les capteurs magnétiques sont intéressants par leur fonctionnement sans contact. On commence par exposer les principes des capteurs magnétiques. Les principales structures de capteurs magnétiques sont présentées. Une nouvelle structure de capteur à aimants permanents et à sondé de Hall est proposée. Ces nouveaux capteurs ont une faible sensiblité aux défauts de réalisation des pièces du circuit magnétique (aimant, pièces ferromagnétiques) et une faible sensibilité à la température. Dans la dernière partie de la thèse, nous comparons les résultats d'une modélisation numérique (éléments finis) et analytique avec ceux mesurés sur un prototype.

Nous avons etudie les proprietes electroniques des agregats d alcalins dans diverses approximations theoriques et dans le cadre du modele du jellium spherique. Pour l'etat fondamental de ces agregats nous avons decrit les electrons delocalises dans l'approximation de hf (hartree fock) et dans la lda (approximation de la densite locale). Nous avons compare les calculs de la lda aux calculs hf obtenus pour la densite et les energies electroniques totales. C'est ce qui nous a permis de confirmer la validite de la theorie de la fonctionnelle densite pour la description de l'etat fondamental d'un systeme fini de fermions. Pour l'etude des modes dipolaires collectives, nous avons considere une excitation electromagnetique. Nous avons aborde la description de ces modes avec les approximations suivantes: l'approximation des phases aleatoires (rpa), l'approximation de la densite locale dependant du temps (tdl-da) et l'approche des regles de somme. En comparant les resultats obtenus par les deux premieres methodes pour les proprietes statiques et dynamiques nous avons pu montrer la validite de la discretisation du continuum dans la rpa. L'etude comparative, que nous avons menee sur l'effet de l'echange et des correlations sur les proprietes electroniques et optiques, a montre que le desaccord observe entre experience et theorie est du essentiellement a l'approximation du jellium faite pour le fond ionique

Le sujet de ce mémoire concerne l'étude de systèmes laser utilisant un cristal de cr#3#+:lisaf comme milieu amplificateur. Ce cristal, découvert en 1989, possède une bande d'absorption, entre 600 et 700 nm, qui encadre la longueur d'onde d'émission des diodes laser rouges en gaalinp (670 nm) et une large bande d'émission dans l'infrarouge proche, entre 800 et 1000 nm. C'est l'un des meilleurs candidats a la realisation de lasers solides accordables pompes par diodes. En prevision de la commercialisation des premieres diodes laser rouges de puissance, nous avons tout d'abord utilise comme source de pompage un laser a krypton ionise emettant a 647 nm et 676 nm. Ce laser nous a permis de tester le cristal de cr#3#+:lisaf dans differentes configurations de fonctionnement. D'une part, en regime continu, nous avons obtenu des performances comparables a celles des lasers a saphir dope au titane; la seule grande difference se situant au niveau des problemes thermiques, beaucoup plus importants dans le cr#3#+:lisaf. D'autre part, en regime impulsionnel, nos systemes laser prouvent que le cr#3#+:lisaf est bien adapte a la production d'impulsions de quelques microjoules, accordables, a un taux de repetition eleve, sur une gamme temporelle s'etalant de la nanoseconde a la femtoseconde. Nous avons, ensuite, defini et realise un laser cr#3#+:lisaf pompe par une diode laser de 500 mw fonctionnant en regime quasi continu. Aujourd'hui (janvier 1994), ce laser est le plus puissant des lasers cr#3#+:lisaf pompes par diode laser rouge mentionnes dans la litterature. Nous avons repris, par la suite, les memes composants optiques pour realiser l'un des premiers lasers cr#3#+:lisaf a modes bloques, pompes par diode, delivrant des impulsions picosecondes accordables sur plus de 70 nm

Nous presentons la construction et l'utilisation d'une experience de spectroscopie terahertz pour la caracterisation de materiaux dans le domaine sub-millimetrique, les mesures etant realisees dans le domaine temporel. Dans une premiere partie, nous decrivons tout d'abord l'experience dediee a la generation et a la mesure d'impulsions electromagnetiques (em) ultracourtes. Nous employons des photocommutateurs sur substrat de lt-gaas excites par une impulsion laser de 100 fs de duree, et utilises comme dipole de hertz. Nous obtenons ainsi des impulsions em de durees voisines de la picoseconde et dont les spectres s'etendent de quelques dizaines de ghz a plus de 2 thz. Pour caracteriser un materiau, ce dernier est positionne entre les antennes emettrice et receptrice. On mesure ainsi sa fonction de transfert temporelle. Par transformee de fourier numerique, on calcule son coefficient de transmission frequentiel, dont on deduit l'indice de refraction et l'absorption intrinseque du materiau. Nous presentons des resultats de caracterisation pour differents cas rencontres en pratique : echantillons optiquement epais, fins (dont les films minces sur un substrat), materiaux anisotropes. Pour traiter tous ces cas, nous proposons une methode originale d'extraction des parametres materiaux. Nous montrons aussi que l'epaisseur precise des echantillons peut etre simultanement deduite de ces mesures. Cette technique peut aussi etre utilisee pour une etude dynamique de materiaux. Nous avons construit une experience pompe (optique) - sonde (thz). Nous avons teste plusieurs materiaux semi-conducteurs, et compare les resultats avec ceux obtenus avec une experience pompe - sonde tout optique. Nous analysons ces resultats, en particulier pour des echantillons de semi-conducteurs iii-v.

La tematica dell'intelligence collection in tempo di pace rappresenta un argomento complesso e al tempo stesso insolito per uno studio di diritto internazionale; tale problematica, infatti, è quasi completamente non regolamentata a livello internazionale e, con la sola eccezione del diritto di guerra, il diritto internazionale pubblico non affronta direttamente la questione della legittimità (o della illegittimità) di tali operazioni. L'intelligence collection è, del resto, storicamente e logicamente connessa alle tradizionali attività di spionaggio il quale, secondo un classico adagio, è il secondo più antico mestiere del mondo. In verità, il diritto internazionale generale si è evoluto in maniera tale per cui le attività di intelligence collection sono divenute una “longstanding practice” diffusa tra tutti gli Stati e se la penetrazione nel territorio di un altro Stato al fine di raccogliere informazioni in tempo di pace confligge potenzialmente con il principio consuetudinario dell'integrità territoriale, tuttavia il diritto internazionale non proibisce specificamente le attività in parola. Di contro, la raccolta di informazioni senza il consenso dello Stato-target nel suo spazio territoriale viola la sua domestic jurisdiction ma il fatto che tale attività sia proibita dal diritto nazionale non comporta necessariamente la possibilità di affermare che questa sia di per sé illegittima da un punto di vista internazionale. Questo lavoro parte dunque dal problema fondamentale se ottenere informazioni senza il consenso dello Stato che le controlla sia di per sé consentito, proibito, o per lo meno regolato dal diritto internazionale, e con quali restrizioni.

O presente estudo propõe um novo modelo de análise que relaciona os conceitos de comportamentos de gestão do tempo (Macan, 1994, 1996), ritmo de distribuição do esforço (Gevers et al., 2015), liderança temporal (Mohammed and Nadkarni, 2011), tempo disponível e autonomia no trabalho (Hornsby et al., 1999) com o objetivo de analisar as relações existentes entre si. A partir da análise de 176 respostas de chefias de equipas a um questionário, os resultados indicam a importância de comportamentos ligados ao estabelecimento de objetivos seguidos pelos comportamentos relacionados com a preferência pela organização no contexto dos comportamentos de gestão do tempo, demonstrando como ambos promovem um estilo constante de distribuição do esforço na execução de tarefas dentro de prazos préestabelecidos. Por sua vez verificou-se uma associação positiva entre este estilo de distribuição de esforço e a liderança temporal. Em relação à perceção subjetiva de falta de tempo não foi encontrada nenhuma associação significativa com os estilos de distribuição de esforço (steady e deadline pacing style) o que sugere que essa sensação não está relacionada com a forma como distribuímos o nosso esforço na execução das tarefas mas, com comportamentos de gestão de tempo deficientes.
This study suggests a new model of analysis that relates the concepts of time management behaviors (Macan, 1994, 1996), pacing style (Gevers et al., 2015), team temporal leadership (Mohammed and Nadkarni, 2011), time availability and work discretion (Hornsby et al., 1999) in order to analyze the interplay between them. Departing from 176 team leaders responses to a survey, results show the importance of behaviors linked to the establishment of goals followed by behaviors related to the preference for organization in the context of time management behavior, demonstrating how both promote a steady pacing style of effort distribution in performing tasks within the deadlines. In turn there was a positive association between the effort distribution and the temporal leadership. Regarding the subjective lack of time perception there was no significant association with the distribution of effort (steady and deadline pacing style) which suggests that this perception is not related to how we distribute our efforts in performing the tasks but with poor time management behaviors.

Also we want to compare the pace of the opening and closing games, similarly we want to compare the pace of the game in rally in matches with the participation of the selected player. Method: The basic method, which has been used in this thesis, is the notational system analysis. The subject of this method was the indirect observing of video recordings 11 women's singles matches at the US Open 2018. The variables monitored were the replacement time and the number of beats in rally. There was a condition for the minimum number of strokes played in rally, which was four or more strokes between players. Based on the recorded data, the pace of the game was calculated by dividing the rally time and beats. Results: The average pace of the game is 1,48 ± 0,06 seconds. The average number of strokes in rally is 6,68 ± 0,9, the average rally time is 9,86 ± 1,35. The average pace of rally in the post-filing session was 0,11 seconds slower than the pace of rally in the second post. The...

With the rise of user-centered design in design practice, the designed image for the homepage of a website influences users’ impression on that website. Therefore, incorporating warm, interactive, and humanized experience into image design can evoke users’ emotions and facilitate forming satisfactory user experience. However, the value of design has been challenged by the convenient function of copying provided by digital technology in the current market where the pursuit of rapid, economical, and convenient services has been a trend. Accordingly, this study explored the creative thinking of webpage design and expected that the research implications can be a reference for webpage designers. Folk beliefs are expressions of the collective consciousness of a society, and the image of Taiwan can be represented by the culture of Mazu. Temples have the function of consolidating ethnic emotions and serve as a crucial intangible cultural asset symbolizing Taiwanese people’s folk culture and cultural identity. This study clarified whether the design content and aesthetic value in a digitalized field of folk belief can be enhanced toward the goal of connecting Mazu worship and social implications. By embedding cultural consciousness in webpage design, this study expected to develop a design with symbolic meanings and identification images and further establish an interactive and emotional image experience model. The objective of this study was to investigate users’ visual perceptions of images on the basis of users’ aesthetic experience of the website homepage design, thereby understanding the relationship between design image and cultural consciousness. Finally, a user experience-based model of creative design thinking was constructed. This study adopted content analysis, the KJ method, and in-depth interview to conduct a comprehensive analysis. The results showed that the words that were used most by the users to describe the design image of the homepage of the Mazu Temple website were related to solemn, traditional, and festive images, and the categories of image perceptions identified by the users were style, graphics, color, and emotion. From the visual and emotional aspects, a cross matrix image model was constructed. It was employed to determine that the design representations of the website homepage were mostly traditional and involved textual interpretations as well as to clarify the historical context of Mazu worship. Moreover, the interview results revealed that in design practice, visual languages can be extracted from local development and phenomena and can then be used as the design representations of cultural consciousness of the Mazu temple. Based on the research results, this study suggested that designers’ reflections on cultural consciousness and their development of in-depth creative design thinking is indispensable. In other words, the interpretation of design image depends on individual designers’ awareness of cultural phenomena. Design representations with emotional images can help enhance the competitiveness of the webpage design for the Mazu temple.

O presente trabalho surge no âmbito da unidade curricular Relatório, incluída no Mestrado de Biotecnologia e Inovação Alimentar da Universidade Católica Portuguesa (UCP) Porto. O estudo do desenvolvimento do produto “Healthy snack of cheese cubes & a dried fruit mix in a convenient pack” teve várias motivações, nomeadamente as alterações nos hábitos alimentares dos consumidores que cada vez mais procuram por refeições saudáveis em forma de snacks fáceis de transportar, de consumo rápido e higiénico, de acordo com um estilo de vida ativo, apressado e sem pausas. O principal objetivo deste projeto foi o estudo do tempo de vida útil e a especificação de quais as características de produto mais adequadas para suportar esse mesmo tempo. Para isso, preparam-se amostras das diferentes referências de queijo, N e M, com vários tempos de maturação e para o caso do queijo M com distintos valores de extrato seco e ainda com anti-aglomerante. Para o queijo N foi estudada uma combinação de Frutos Secos (Mix 1) e para o queijo M outra combinação (Mix 2) que ocupam outro alvéolo na mesma embalagem que o queijo. As amostras foram embaladas em duas combinações diferentes de materiais de embalagem. Foi feito um acompanhamento das mesmas amostras através de analises sensoriais, físico-químicas e microbiológicas. Além disso, foram feitas medições da composição da mistura gasosa utilizada nas embalagens para entender qual a evolução da mesma com o tempo de armazenamento. Realizou-se também um estudo complementar com o objetivo de perceber o comportamento do produto em condições adversas de altas temperaturas. Os resultados das análises realizadas mostraram que, para o queijo N não existiu um tempo de maturação que se tivesse evidenciado, concluindo-se apenas que dentro do intervalo de 28 a 42 dias de maturação dois dos lotes estudados conseguiram manter as suas características durante os 125 dias de vida útil. No caso do queijo M, houve uma amostra que se evidenciou. A mesma amostra apresentava um valor de extrato seco maior que as restantes e foi a única que não demonstrou problemas de colagem do queijo. A utilização de anti-aglomerante no queijo M com menor valor de extrato seco não solucionou os problemas de colagem. As duas combinações de embalagem testadas mostraram ser eficazes na sua função sendo que as diferenças em termos sensoriais, físico-químicos, microbiológicos e na composição da mistura foram praticamente nulas.
The present work is part of the curricular unit Final Report, included in the master’s in biotechnology and Food Innovation at the Catholic University of Portugal (UCP) Porto. The study of the development of the product Healthy snack of cheese cubes & a dried fruit mix in a sustainable pack had several motivations, namely the changes in the eating habits of consumers who increasingly look for healthy meals in the form of easy to-carry snacks, of fast and hygienic consume, in line with an active, hurried lifestyle with no breaks. In addition to this trend, the theme of sustainability is also increasingly prominent in society and the demand for sustainable packaging has also motivated the company for this concept. The main objective of this project was the study of the shelf life and the specification of which product characteristics are most suitable to withstand that same time. For this, samples of the different cheese references, N and M were prepared, with different maturation times and for the case of M cheese with different dry matter values and also with anti-caking agent. Two mix of dried fruits were studied, for N cheese one combination (Mix 1) and for M cheese another combination (Mix 2). The samples were packaged in two different combinations of packaging materials. The same samples were monitored through sensory, physical-chemical and microbiological analyzes. In addition, measurements of the composition of the gaseous mixture used in the packaging were made to understand its evolution with the storage time. A complementary study was also carried out in order to understand the behavior of the product in adverse conditions of high temperatures. The results of the analyzes carried out showed that, for N cheese, there was no maturation time that was evident by differences in the parameters assessed, concluding that within the interval of 28 to 42 days of maturation two of the studied batches managed to maintain their characteristics during the 125 days of shelf life. In the case of M cheese, there was a sample that showed differences. This sample had a higher dry matter value than the others and was the only one that did not show cheese sticking problems. The use of an anti-caking agent in M cheese with a lower dry matter value did not solve the gluing problems. The two packaging combinations tested proved to be effective in their function and the differences in sensory, physicochemical, microbiological and composition mixes were practically zero.

Methods: The methods used in this thesis are indirect observation and system notation analysis. When evaluating the overall average of all variables from 10 matches at Maia Open 2019, the number of players was N = 17, with an average placement of ATP M = 442,8 ± 272,0. When evaluating the overall average of all variables from 10 matches at RPM Prague Open 2019, the number of players was N = 13, thereof players N = 8 with an average placement of ATP M = 529,0 ± 77,6 and players N = 5 with an average placement of ITF M = 832,6 ± 578,6. The monitored variables were rally time, time out length and the number of hits. The game pace was calculated from the rally time and the number of hits. The relationship load was evaluated from the time out lenght and the rally time. Results: The average game pace is 1,36 s at Maia Open 2019....

O presente estudo pretende reflectir sobre a gestão do tempo na sala de aula e a sua eficaz distribuição pelas tarefas da lesson plan, para que as mesmas sejam integralmente lecionadas em cada aula. Para isso, procedeu-se ao planeamento de 18 aulas, à sua concretização em sala e à medição dos tempos de cada tarefa, com o objetivo da melhoria contínua da gestão do tempo em cada aula. O professor é um administrador do tempo e ritmo na sala de aula e a sua gestão eficaz resulta numa aprendizagem mais consistente por parte dos alunos. Nesse sentido, para maximizar o tempo das aprendizagens, o professor deverá ter em conta uma gestão do tempo das atividades em contexto de aula, assim como utilizar um ritmo continuo durante a execução das mesmas. As conclusões do estudo permitem considerar que a prática e a experiência de várias aulas contribuíram para uma efetiva melhoria, quer na planificação das aulas, quer na sua gestão do tempo. As aulas foram gravadas, os tempos atribuídos a cada atividade foram aferidos e constatou-se, assim, que a estagiária conseguiu gerir melhor o tempo e o ritmo, de modo a cumprir a planificação conforme estava estipulad
This study intends to reflect on time management in the classroom and the effective distribution of tasks so that lesson plans are fully taught in each class. In order to do this, eighteen lessons were carefully planned, taking into account their implementation in the classroom and the time dedicated to each task, aiming to continuously improve my time management in each lesson. The teacher is the manager of time and pace in the classroom and effective management enables more consistent student learning. Therefore, in order to maximize the students’ learning process, the teacher must thoroughly consider the amount of time dedicated to each activity in the classroom, as well as the need to provide an appropriate pace of each given task. Conclusions of this study show that the experience and practice of several classes contributed to an effective improvement in both lesson planning and time management. The classes were recorded, the times assigned to each activity were checked and it was verified that the trainee was able to better manage the time and pace in order to fulfill the plan as stipulated.

Title: Analysis of squash rally pace in male and women matches Objectives: This paper aims to evaluate the game pace of squash from the perspective of various factors, such as: gender of players, difference between winners and losers, number of strikes within different height levels of front wall, average duration of a rally, and types of strikes. Methods: The main method used to achieve the objectives of this thesis is the notational analysis. This method is based on observing the available video recordings - there were 25 of these, obtained from different PSA tournaments in years 2017 - 2020. We were sampling data about the duration of a rally, number and type of strikes and a duration of each type. Subsequently, we deducted information about the pace of the game and used it to further analyze and interpret the pace in relation to possible variables.. Results: The objective of the paper has been completed, as we have answered all the research questions. The average pace of the serve is 1.345 seconds for men and 1.388 seconds for women, while the average duration of rally is 25.06 seconds for male players and 17.22 seconds for female players. The results suggest that the game pace, its relevant variables, game development and final results are different for male and female squash players....

Il presente lavoro nasce con l’obiettivo primario dello studio organico del teatro romano della città di Pollentia-Urbs Salvia. Sebbene infatti sulla città e sui suoi principali monumenti esista un’ampia letteratura e rilevanti contributi recenti, ancora sostanzialmente inedito sin dalle prime indagini scientifiche condottevi a partire dalla metà del secolo scorso, rimaneva proprio l’edificio teatrale. Questo, quale monumento chiave nell’ambito dell’urbanistica della città tardo-repubblicana e augustea ed è oggetto infatti, nel corso degli anni, di brevi cenni e di contributi parziali ma mai esclusivi. Un nuovo rilievo del monumento ha consentito di chiarirne la genesi e l’esistenza di diverse fasi architettoniche giungendo alla precisazione cronologica di quattro diverse fasi edilizie. Una prima fase relativa all’impianto dell’edificio originario inquadrabile tra la fine dell’età tardo-repubblicana, contestualmente alla fondazione della colonia e il 23 d.C., anno entro il quale, come documentata dall’epigrafe di C. Fufius Geminus, il primo teatro dovette essere completato. Una seconda fase inquadrabile orientativamente tra l’età tiberiana e l’età claudia che, in concomitanza con la costruzione dell’imponente complesso del tempio-criptoportico - conclusione monumentale della risistemazione urbanistica della città avviatasi in età augustea -, vede il massiccio intervento di ampliamento strutturale e planimetrico dell’edificio; una terza ed ultima fase in età domizianea che, come documentato anche dall’epigrafe di C. Salvius Liberalis e C. Salvius Vitellianus, è contrassegnata da una serie di interventi di ornamento e restauro e, soprattutto, dalla costruzione del piazzale porticato restrospiciente l’edificio stesso. Sulla base dell’inquadramento cronologico di una parte delle sculture provenienti dal teatro a tale fase pare verosimile ipotizzare sia seguita, in età adrianea-antonina, un’ulteriore fase forse dedita all’abbellimento della ornamentazione dell’edificio. Con l’obiettivo di una comprensione organica del monumento si è infine proceduto all’esame dei materiali architettonici, scultorei ed epigrafici da esso provenienti. Il lavoro di raccolta e censimento svolto sui materiali provenienti dai vecchi scavi effettuati ha messo in evidenza la dispersione, per alterne vicende, di gran parte del materiale e l’inevitabile decontestualizzazione del restante e reso necessaria un’analisi di tipo essenzialmente archivistico e bibliografico, focalizzata soprattutto sul consistente apparato scultoreo ritenuto appartenente all’edificio, finalizzata ad istituire nuovamente la connessione tra contesto di provenienza e documentazione d’archivio. Sebbene solo in casi isolati, ed esclusivamente per le sculture, sia stato possibile giungere ad ipotizzare la collocazione precisa di taluni elementi nell’ambito dell’edificio stesso, l’indagine effettuata sugli elementi ornamentali ed epigrafici è risultata di fondamentale importanza per meglio definire e sostanziare le diverse fasi edilizie e di ristrutturazione individuate ed all’interno delle quali gli stessi materiali sembrano trovare oggi una più adeguata collocazione cronologica e stilistica
