Full textAbstract:
L’efficacité d’une enceinte de traitement thermique dépend des conditions thermo-aérauliques de l’écoulement interne des phases en réaction. De ce fait, la détermination de la Distribution des Temps de Séjour (DTS) de phases a été une méthode d’analyse globale longtemps utilisée en Génie des Procédés. Elle est un paramètre essentiel pour une bonne interprétation des processus macroscopiques réactionnels dans les unités de traitement. Elle permet aussi de diagnostiquer et d’optimiser les conditions de fonctionnement des installations thermiques. Les techniques pour la détermination de la DTS des phases solides sont plus complexes à mettre en œuvre que celles des phases gaz. Le choix du traceur dépend alors de la méthode utilisée pour détecter le lot de particules traçantes à l’entrée et à la sortie du réacteur. Certaines techniques ont été développées dans le but d’une détermination simple de la DTS solide, mais la plupart des techniques perturbatrices de l’écoulement principal. Dans ce travail, on développe un nouvel outil pour la détermination de la distribution des temps de séjour de la phase solide, basée sur la luminescence de particules préalablement enrobées de pigments phosphorescents. Cette méthode optique, non intrusive et souple d’emploi, a été d’abord mise en place à l’échelle laboratoire, sur un banc d’essais aéraulique. Elle a ensuite été appliquée sur un Lit Fluidisé Circulant (LFC), en vue d’une validation à l’échelle semi-industrielle. Son couplage avec une technique DTS gaz par traçage à l’hélium, a permis de déduire certains paramètres d’écoulement tels que la vitesse moyenne de glissement solide/gaz et le taux du transport diphasiqueThe efficiency of a heat treatment chamber depends on thermo-aeraulic conditions of the internal flow of phases in reaction. Thus, the determination of the Residence Time Distribution (RTD) was a global method of analysis used a long time in process engineering. It is a key parameter for a good interpretation of the macroscopic reactional processes in the processing units. It permits also to diagnose and to optimize the functioning conditions of thermal installations. The techniques for the determination of the RTD of solid phases remain delicate and complex to implement than those of gas phases. The choice of tracer depends then on the method used to detect the batch of tracer particles at the inlet and outlet of reactor. Some techniques were developped with the goal of as a simple determination of the solid RTD, but most are disruptive methods of the main flow. In this work, we develop a new tool for determining the distribution of residence time of the solid phase, based on the luminescence of the particles previously coated with phosphorent pigments. This optical method, non-intrusive and flexible employment, was first put in place at the laboratory scale, on an aeraulic trial bench. It was then applied on a circulating fluidized bed (CFB), in order of the validation at the semi-industrial scale. Its coupling with a gas RTD technique by tracing with the helium, has permit to deduct flow parameters such as average speed slip solid / gas and the void fraction of the diphasique transport

Le législateur impose la règle des 3T pour un bon fonctionnement des installations de traitement thermique des déchets. Les niveaux minimum de température de traitement et l'excès d'air peuvent être facilement vérifiés. Or, le temps de séjour minimum des fumées souffre d'une absence de possibilité de contrôle sur site. C'est là l'une des avancées du présent travail qui mène à la caractérisation de l'aéraulique interne des enceintes chaudes. Non seulement, grâce à la méthodologie développée, il est désormais possible de mesurer les temps de séjours effectifs des gaz dans une enceinte de traitement thermique en cours de fonctionnement, mais il est également possible d'analyser les pathologies d'écoulement interne des fumées dans une installation donnée, par analyse de la distribution des âges internes des molécules gazeuses constituant les fumées. Ce type de mesure peut être réalisé sur site, grâce à un ensemble métrologique d'injection/détection portable. On étend la méthodologie, à la détermination de la distribution des temps de séjour particulaires (DTSS). Le système de prélèvement/analyse mis en place, a été appliqué dans un premier temps à la caractérisation des écoulements gaz/solide d'une maquette de lit fluidisé circulant. Dans un second temps, ce système a été utilisé pour la procédure de détermination des temps de séjour solide (DTSS). Enfin, le couplage de la méthodologie DTSS avec la méthodologie DTSG, a été appliqué pour la détermination des paramètres aérauliques d'un écoulement gaz/solide (les vitesses : gaz, particule et glissement, porosité. . . )The legislature imposes the implementation of the 3T rule in order to ensure a correct conduct and performance of waste heat treatment installations. However, while the minimum levels of treatment temperature and air excess can be easily checked; the time of least residence of fumes suffers from a possible absence of site control. Our work leads to the characterization of hot enclosures internal aerodynamics. Thanks to our developed methodology, from now on, it is not only possible to measure the actual time of gases residence in a heat treatment enclosure during the course of operation; but it is also possible to analyze the internal flow pathologies of fumes in a given installation, and that's by analysing the internal age's distribution of the gas molecules constituting the fume. This type of measurement can be carried out on site, thanks to a portable injection\detection metrological set. We extended the mentioned methodology, to the determination of the residence time distribution particulate (SRTD). The existing sampling/analyzing system was initially applied to the characterization of solid/gas flows of a circulating fluidized bed model. Then, it was used for the procedure of the determination of solids residence time (SRTD). Finally, the coupling of the SRTD methodology with the GRTD methodology, was applied on the determination of gas/solid flow aeraulic parameters (velocities: gas, particle and slide, porosity. . . )

MBA Professional ReportStudy compares airline tickets purchased through the Defense Travel System (DTS) for Naval Postgraduate School (NPS) travelers to prices for similar tickets available at online travel agent (OTA) and carrier websites. The study's purpose is to determine if prices are significantly different and if savings can be achieved by purchasing tickets from different sources. The study finds that DTS tickets are cheaper than carrier refundable tickets, but more expensive than nonrefundable carrier and OTA tickets. Sensitivity analysis indicates nonrefundable tickets would have to average 1.83 and 2.72 changes per ticket, before itinerary changes offset cost savings for nonrefundable carrier and OTA tickets purchased, respectively. Similarly, 26% and 39% of nonrefundable carrier and OTA tickets would have to be canceled to offset saving. Ultimately, this study can help determine if traveler flexibility achieved by purchasing refundable DTS tickets at negotiated "city-pair" rates from carriers is worth the additional cost. This study shows the flexibility achieved through DTS refundable tickets available in the city-pair program comes with a cost; which is the potential savings that could be achieved by using nonrefundable tickets. Annualized, potential savings at NPS could amount as much as $2 71,007 if there are no itinerary changes or cancellations.

Full textAbstract:
L'expérience DTS (Derviche Tourneur Sodium) permet d'étudier le régime magnétostrophique attendu dans les noyaux planétaires, où les forces de Coriolis et de Lorentz sont en équilibre. Elle consiste en la rotation différentielle de deux sphères concentriques dont l'espace inter-sphère contient du sodium liquide. De plus, un champ magnétique dipolaire est imposé avec une graine aimantée. Cet écoulement magnétohydrodynamique de Couette sphérique est analysé grâce à des mesures de vitesse (Doppler ultrasonore), de potentiel électrique et de champ magnétique induit.Les profils de vitesse angulaire mettent en évidence différentes régions dans le fluide : une zone de super-rotation près de la graine, un plateau, et une décroissance lente à la sphère externe. Ceci est bien expliqué par un modèle basé sur l'état de Taylor modifié où la turbulence dans les couches d'Ekman est prise en compte. Quant à la turbulence dans le volume, elle est faible, et les fluctuations observées sont associées à des ondes.
La dispersion des mesures pour un forçage donné pourrait être due à des variations de couplage électrique entre le sodium liquide et la graine en cuivre. L'utilisation de la différence de potentiels électriques, comme équivalent de la vitesse du fluide, amène la découverte d'un régime particulier quand les sphères sont contra-rotatives. Les fortes amplitudes du champ magnétique induit nous laissent penser que cette situation pourrait être favorable à l'obtention d'un effet dynamo.
Les récentes expériences ont montré un bon couplage électrique, et des mesures innovantes de champ induit, tout le long d'un méridien et à l'intérieur de la sphère, apportent de nouvelles contraintes.

Previous issue date: 2017-02-24O espalhamento Raman espontâneo é um efeito decorrente da interação de um campo eletromagnético com as moléculas do meio no qual o mesmo se propaga. Tal efeito possui forte dependência com a temperatura, encontrando portanto, aplicações em sensoriamento. Neste trabalho a modelagem deste efeito em fibras ópticas para aplicação em sensoriamento distribuído de temperatura é abordada. A princípio foi realizada uma revisão da literatura para levantar os parâmetros fundamentais e posteriormente as equações para gerar o efeito Raman espontâneo foram implementadas em software Matlab. Uma vez definido o modelo sensor proposto, simulações considerando diversos parâmetros e configurações foram analisadas com a finalidade de estudar como tais parâmetros afetam o desempenho do sensor aqui modelado. A partir do perfil de temperatura obtido, o desempenho do sensor foi verificado através do seu alcance, resolução espacial e de temperatura. Dessa forma, este estudo fornece princípios fundamentais de como dimensionar sensores distribuídos de temperatura em fibras ópticas baseados no espalhamento Raman espontâneo. Apresenta-se uma visão otimizada no desenvolvimento de sensores que atendam as necessidades da indústria, principalmente no monitoramento de grandes estruturas, onde o conhecimento de mudanças bruscas de temperatura é fundamental na preservação tanto das áreas monitoradas como principalmente da segurança de pessoas que trabalhem em tais locais.

Full textAbstract:
La red vial de Chile cuenta con 80.523 km, de los cuales sólo 17.245 km están pavimentados.
Con el propósito de aumentar la red vial pavimentada a un menor costo, el Ministerio de Obras
Públicas, a través de las Direcciones Regionales de Vialidad, han aplicado el uso de estructuras
económicas de pavimentos granulares con coberturas asfálticas delgadas. Una de estas coberturas
es el Doble Tratamiento Superficial (DTS) que hasta hoy sólo se ha usado en caminos con
tránsito medio a bajo, no superando en la actualidad los 1 - 1,5 Millones de Ejes Equivalentes
(MEE).
El presente estudio se enmarca dentro del convenio suscrito entre el Laboratorio Nacional de
Vialidad (LNV) y el Instituto Chileno del Asfalto (ICHAS) y consistió en verificar si este tipo de
solución, responde de manera satisfactoria en caminos con mayores solicitaciones de tránsito.
Para verificar el resultado de dicha experiencia, se eligió como base el contrato “Reposición
de la Ruta 5 Norte, Sector Chañaral – Límite II Región”, de largo 22,75 km, que se ubica entre
los paralelos 25º 56’ y 26º 20’Latitud Sur y meridiano 70º 30’ Longitud Oeste. Esta obra incluyó
una capa de base granular con superficie de DTS convencional, sobre el pavimento existente.
El desarrollo del trabajo consistió en establecer la condición original de la estructura de
pavimento, para luego determinar y comparar la condición actual mediante mediciones de
resistencia estructural, funcionalidad y durabilidad. Con esto, más una inspección visual, se logró
definir la forma, magnitud y frecuencia del deterioro producido.
En general, la estructura ha respondido satisfactoriamente frente a las solicitaciones de
tránsito desde su puesta en servicio y momento actual, años 2004 y 2008 respectivamente. Los
posibles daños presentados en este tipo de solución, se asocian a las condiciones ambientales, de
drenaje, geometría y diseño estructural del pavimento.
Los resultados en cuanto al comportamiento de la estructura sometida a tránsito medio a alto
son promisorios. No obstante, para el futuro de esta investigación, se sugiere continuar con este
seguimiento mediante una metodología genérica que incluye mediciones periódicas de su
condición estructural y funcional.

Full textAbstract:
Infiltration and inflow (I/I) are common problems in the foul sewer system. A method to detect I/I that is not commonly used in Sweden is DTS, Distributed Temperature Sensing. DTS is based on continuous measurements of temperature over a predetermined distance in the sewer system. The I/I is detected as temperature differences in the temperature data that is registered in the sewer system. The measurements often take place over a couple of weeks or months in the sewer system. The aim of this project was to review previous studies where DTS was used to detect I/I in foul sewers. Data from a wastewater treatment plant in Umeå together with meteorological data were analysed to be able to visualize the problem of I/I and then suggest how DTS can be applied in Sweden. Both automated and visual analyses was performed to find if there were any relationships between wastewater temperature, wastewater flow and precipitation. The outcome was that it is possible to apply DTS in the foul sewages to detect I/I. DTS seemed to be able to detect I/I in all types of sewage material, however it is dependent on that the I/I temperature differs from the temperature of the foul sewage water. It is an expensive technique but if it is meant to be used many times to analyse bigger areas it can be worth the costs. If larger areas are to be investigated, the costs for DTS and current methods are approximately the same. At the wastewater treatment plant in Umeå, a slight relationship between wastewater temperature, wastewater flow and precipitation could be detected. The degree of dilution was calculated to 1,34 which means that about 25% of the sewage water is I/I. The conclusion from this was that I/I exists in the foul sewers in Umeå. The leakage points could not be located with this analysis. DTS could be a possible method to detect the leakage points of I/I in foul sewers. Unlike smoke tests, colouring and video-inspection of the sewers, DTS might be able to detect smaller leakage points.Tillskottsvatten är ett vanligt problem i spillvattenledningsnätet. DTS, Distributed Temperature Sensing är en metod som inte är vanlig i Sverige för kontroll av spillvattenledningar. Tekniken bygger på kontinuerliga temperaturmätningar under en tidsperiod över en förutbestämd sträcka och registrerar temperaturavvikelser som kan uppstå i samband med inläckage av tillskottsvatten. Syftet med projektet var att granska tidigare utförda studier med DTS för att ta reda på hur tekniken kan användas för att lokalisera inläckage i spillvattenledningar. För att vidare illustrera problematiken med tillskottsvatten i spillvattennätet samt föreslå hur DTS kan appliceras i Sverige genomfördes en analys av mätdata på inkommande vatten till reningsverket på Ön, Umeå. Både visuella och automatiserade analyser genomfördes där tolkningar gjordes utifrån mätdata från reningsverket tillsammans med nederbörds- och lufttemperaturdata. En regressionsanalys genomfördes som automatiserad analys för att undersöka eventuella samband mellan spillvattentemperatur, spillvattenflöde och nederbörd. Projektet inleddes med en litteraturstudie där det utreddes hur DTS fungerar teoretiskt och praktiskt. Litteraturstudien visade att DTS är praktiskt möjligt att applicera i spillvattenledningsnätet för att leta inläckagepunkter för tillskottsvatten. Inläckage kan registreras som ökningar eller sänkningar i spillvattentemperaturen beroende på lufttemperaturen. Den är inte beroende av material på ledningarna men däremot är DTS beroende av att tillskottsvattnet är av annan temperatur än spillvattnet. Det är en dyr teknik men kan vara värt investeringskostnaderna om mätningar tänkt ske många gånger under längre perioder. Vid kontroll av större områden med hjälp av röktest kombinerat med färgning av vatten och filmning är kostnaderna ungefär de samma. Utifrån mätdatan från reningsverket och nederbördsdatan från Umeå universitet kunde vissa samband påvisas mellan spillvattentemperatur, spillvattenflöde och nederbörd. Ett visst samband kunde även urskiljas mellan spillvattentemperatur och spillvattenflöde. Utspädningsgraden av spillvattnet beräknades till 1,34 vilket innebär att cirka 25% av vattnet i spillvattenledningarna är tillskottsvatten. Slutsatsen som kunde dras utifrån detta var att tillskottsvatten existerar i spillvattenledningsnätet som leder till reningsverket på Ön i Umeå. Däremot kunde inga slutsatser dras för att säga var inläckage av tillskottsvatten sker. DTS skulle kunna appliceras i ledningsnäten för att undersöka närmare var inläckagepunkterna är och tillskillnad från rökning, färgning av vatten och filmning som används idag kan DTS sannolikt upptäcka fler typer av inläckage.

Magíster en Tecnologías de la InformaciónLa División de Sistemas de Autoservicio de la empresa DTS, ha pasado en los últimos años de ser un fabricante más de hardware de autoservicio a ser el principal proveedor de soluciones integrales en este rubro. Este cambio trajo consigo el surgimiento de diversos problemas en el ámbito del desarrollo de software, debido principalmente a la carencia de un proceso formal. Con el fin de resolverlos, la Gerencia decidió dar inicio a un proyecto de mejora sistemática del proceso de desarrollo de software, cuyo primer paso y objetivo principal de esta Tesis, sería la formalización de dicho proceso, y cuyos objetivos secundarios serían su evaluación, detección de posibles problemas y corrección posterior de ellos. Para la especificación del proceso se decide usar lenguaje SPEM 2.0 en vez de documentos de texto, notación formal que permite algún tipo de procesamiento automatizado posterior. Como herramienta de especificación se determina el uso de EPF Composer, entorno gráfico que facilita la tarea de formalización. Finalmente, para la evaluación del proceso e identificación de anomalías, se establece el uso del método Process Model Blueprints, modelo desarrollado por alumnos de doctorado del DCC de la Universidad de Chile. En principio se procedió a adquirir conocimiento sobre SPEM 2.0 y EPF Composer. Luego, en base a entrevistas efectuadas al personal de la División y al registro documental de proyectos pasados y en ejecución, se identificaron las tareas, roles y artefactos del proceso, los que fueron clasificados en un determinado número de áreas de proceso CMMI. Más tarde, se definieron los subprocesos fundamentales efectuados en la organización, los que finalmente fueron ensamblados en el proceso de desarrollo de software de la División. Este proceso ya formalizado, fue evaluado usando Process Model Blueprints, detectándose una serie de anomalías en cada una de sus tres vistas (roles, tareas y productos), las que fueron analizadas y corregidas cuando correspondía hacerlo. Todos los objetivos planteados en esta Tesis fueron cumplidos de acuerdo a lo establecido, logrando contar al final del trabajo con un proceso especificado formalmente, evaluado según un conjunto de criterios, y mejorado a través de la corrección de las anomalías detectadas. Dentro de las lecciones aprendidas, se detecta entre otras cosas, que un análisis inicial más exhaustivo del problema planteado podría haber evitado el cambio posterior de los objetivos; además, se postergó la creación de guías para ciclos de mejora futuros, cuando éstas entregan tanto o más valor a los usuarios que la formalización del proceso. Como trabajo futuro, entre otras iniciativas, la División ha decidido participar en ADAPTE, proyecto que busca encontrar una nueva estrategia de adaptación de procesos que permita enfrentar proyectos de distinta naturaleza con un proceso especialmente adaptado a cada uno de ellos.

Esta pesquisa foi motivada por nossa experiência de quartorze anos como psicólogo no CRT Centro de referencia e Treinamento em DST/Aids. Tem como objetivo principal o estudo das relações estabelecidas entre os psicólogos, que estão na assistência, com as instituições que embasam seu trabalho: a Formação universitária e o Programa de DST/Aids. Isso se deve ao fato de que os profissionais se apropriam de formas muito variadas, tanto com relação aos aspectos contidos na formação, quanto frente as estratégias difundidas pelo Programa. Algumas vezes essas relações são produtoras de conflitos para a prática do profissional, uma vez que se estabelecem frágeis diálogos com aquilo que a configuração do Programa destina ao trabalho do psicólogo. Sendo assim, nossas perspectivas nessa pesquisa nos insere como sujeito do processo que descrevemos, na medida em que nossa primeira observação parte da experiência enquanto profissional. Para a realização da presente investigação examinamos a formação da psicologia no Brasil e suas principais características legadas. Em seguida, estudamos os processos em que os psicólogos entram para o serviço público de saúde principalmente o SUS, em seguida descrevemos e analisamos as passagens realizadas pelo profissional de psicologia no Programa de DST/Aids. Realizamos entrevistas com quatro psicólogos da instituição que estão em diferentes setores. Compreendemos nossos entrevistados a partir das posições teóricas de René Kaës sobre o sujeito do inconsciente como sujeito do grupo, juntamente com as formações psíquicas exigidas nesses processos. Vimos ao final, que os psicólogos apresentam uma série de pactos organizados pelas Alianças Inconscientes posição teórica definida por esse autor. Tais pactos surgem para produzir determinados apaziguamentos de conflitos que surgem no exercício das atividades dos psicólogos e para que se estabeleça algum nível de adaptação. Discutimos por fim que os processos que sustentam e constroem os pactos institucionais tendem a tornar, como processos defensivos, o enfrentamento das contradições e tensões de modo mais suportável. No entanto, tem-se perdas e prejuízos significativos nesses processos, na medida em que as possibilidades criativas do trabalho e a execução de atividades sofrem ameaças; há perdas que se deve enfrentar. Tais enfretamentos devem estar no âmbito da universidade, do diálogo entre esta e as demandas que se estabelecem pela área da saúde e finalmente pela formação de profissionais mais investigadoresThis research has been motivated from our fourteen years of experience as psychologist at CRT Centre of Reference and Training on IST/Aids. We have been observed such as different forms of appropriations of the strategies from the programme; sometimes traditionally or others in conflict, by psychologist community. The observation of conflicts related to new needs of approaches in the Aids fields was kept along all our experience in the institution. The forms from which psychologists use the university education in order to give them background are not always steady among them. So, this present work aims to investigate the relations built and kept by psychologists with those responsible institutions for their carrying out work: University Education and the IST/Aids Programme public policies. As first plan, we developed investigation on the origins of psychology in Brazil, considering its main aspects and trends. As following, we studied the formation and organization of public health in Brazil and the belonging process of psychologists to this. After this we studied and analized aspects of the appropriation by psychologists in the IST/Aids Programme and its proposed strategies, in order to verify how psychologists handle with strategies which might be familiar or not to them. We interviewed four psychologists who act out in distinct sectors of CRT. Some of them are much more closed to a sort of clinical work and the two others act out more closed to the Programme strategies. We understood our subjects of research the psychologists from the theoretical position developed by the french psychoanalyst René Kaës, for whom the subject of unconscious as being subject of the group and in the same time there are the particular psychic formation demanded by such processes. In the end, we could observe that the psychologists have been developed an amount of pacts structured by Unconscious Alliances, theory developed by René Kaës. These pacts occur in order to produce such as appeasement of conflicts, present in the institutional activities and still to promote such a kind of adaptation and belonging to the group. We discussed, as last words, that those institutional pacts work as defensive processes, in order to avoid contradictions and tensions and, by other side keeping the life in institution under control. However, one can notice losses and damages during theses processes in that creative potential and the activities work can be threatened. It is important to face all of this in the field of university in dialogue with the strategies proposed by the public health and, as final, one must face that by building investigator professionals, as well

Lambert, Martin. "Use of a Direction Tolerance System (DTS) in Patients with Low Back Pain: Intra-Rater Reliability and Outcome." Thesis, NSUWorks, 2014. https://nsuworks.nova.edu/hpd_pt_stuetd/49.
Full textAbstract:
Problem Statement: Because of the lack of evidence in support of a pathology-based approach to low back pain (LBP), many researchers advocate the use of classification systems that classify patients with LBP based on common clinical characteristics. Treatment based on direction tolerance can improve circulation, diminish pain and inflammation, restore normal motion, and reduce fear-avoidance beliefs. Treatment performed in the standing position can functionally integrate related regions of the body, can replicate normal tissue loading in standing position, replicate normal proprioceptive demands of motion performed in standing position, and address underlying movement impairments in related regions that may contribute to compensatory tissue pathology in the low back. The problem is that none of the existing functional classification systems for evaluation and treatment of LBP are designed for this purpose. The Direction Tolerance System (DTS) is a new functional classification system that is based on direction tolerance and performed entirely in the standing position. Objectives: The purpose of this research was to investigate the reliability, outcome, and prognostic ability of the DTS for evaluation and treatment of LBP. Methods: This exploratory research was a prospective cohort study with 60 patients seeking physical therapy (PT) for treatment of LBP by 5 different therapists. All patients were evaluated and treated for 8 visits using the DTS. Reliability was measured by comparing DTS scores (DTI) on visits 1 and 2. DTS treatment consisted of a scripted flexibility and strengthening exercise program based on motions that were determined to be non-aggravating during the DTS examination. Outcome was assessed using the DTI, modified Oswestry Disability Questionnaire (ODQ), Numeric Pain Rating Scale (NPRS) and Fear-Avoidance Beliefs Questionnaire Physical Activity Subscale (PABQ-PA). Baseline variables were assessed for correlation with successful outcome and ability to predict a successful outcome. Results: (1) Group intra-rater reliability between visits 1 and 2 using ICC (3,1) was good (.80, p<.001); (2) The group success rate was 62%, which exceeded the expected 50% success rate. (3) Baseline variables were not associated with a successful outcome and did not significantly predict a successful outcome. Discussion: The DTS is a simple, reliable and effective method of evaluating and treating LBP, and with proper training, can be used by clinicians.

Full textAbstract:
Wastewater treatment plants (WWTP) involve several complex physical, biological and chemical processes. Often these processes exhibit non-linear behavior that is difficult to describe by classical mathematical models. Safer operation and control of a WWTP can be achieved by developing a modeling tool for predicting the plant performance. In the last decade, many studies were realized in wastewater treatment based on intelligent methods which are related to modeling WWTP. These studies are about predictions of WWTP parameters, process control of WWTP, estimating WWTP output parameters characteristics. In many studies, neural network models were used to model chemical and physical attributes in the flow rate. In this Thesis, a data-driven approach for analyzing water quality is introduced. Improvements in the data collection of information system allow collection of large volumes of data. Although improvements in data collection systems have given researchers sufficient information about various systems, they must be used in conjunction with novel data-mining algorithms to build models and recognize patterns in large data sets. Since the mid 1990's, data mining has been successfully used for model extraction and describing various phenomena of interest.

Full textAbstract:
Les dysfonctionnements observés dans les enceintes de conversion thermochimique tels que les zones mortes et les courts-Circuits conduisent en général à une mauvaise valorisation de la ressource énergétique et à une pollution atmosphérique. Ils trouvent leur origine dans les conditions aérauliques au sein de ces enceintes. Ils pourront alors être évités par une meilleure maîtrise de ces écoulements. Nous proposons dans ce travail d’une part, le développement d’un nouvel outil pour la détermination de la distribution des temps de séjour de la phase solide, basé sur la luminescence de particules préalablement enrobées de pigments phosphorescents. Cette méthode systémique, optique, non intrusive et souple d’emploi a été mise en place à l’échelle laboratoire sur un banc d’essais aéraulique. D’autre part, nous avons développé un modèle numérique permettant de déterminer la distribution des temps de séjour afin de maîtriser les écoulements à la sortie des enceintes en vue de les optimiser et les extrapoler à l’échelle industrielle. Cette approche analytique est basée sur une modélisation par couplage MFN de type volumes finis du comportement d’un fluide à l’aide du Code Saturne et DEM de type éléments discrets du comportement du solide à l’aide du code SIGRAME. Enfin une confrontation de la DTS du modèle numérique avec laDTS expérimentale a été réaliséeDysfunctions observed in thermochemical conversion reactors like dead zones and short circuits generally lead to inaccurate pricing of energy resources and air pollution. They originate in the air flow conditions in these aeraulic reactor. They can then be avoided by a better control of these flows. We propose in this work to develop a new tool for determining the distribution of residence time of the solid phase, based on the luminescence of particles previously coated with phosphorescent pigments. This optical method, non-Intrusive and flexible, has been implemented at a laboratory scale, on an aeraulic test bench.On the other hand, we have developed a numerical model allowing to determine the distribution of the residence time to master the flows at the exit of surrounding walls to optimize them and extrapolate them at the industrial scale. This analytical approach is based on a modelling by coupling MFN by finite volume types via the Code Saturn and DEM by discrete elements of the solid behavior by means of the code SIGRAME. Finally a confrontation of the DTS of the digital model with the experimental DTS has been done

Full textAbstract:
This thesis is based on a research project to monitor the temperature profile along a power cable using the fibre optic Distributed Temperature Sensing (DTS) technology. Based on the temperature measured by a DTS system, real time condition monitoring of power cables can be achieved.
In this thesis, there are three main research themes.
1. Develop a DTS system for industrial applications. The entire hardware system and measuring software are developed to be an industrial product. Multiple functions are provided for the convenience of users to conduct temperature monitoring, temperature history logging and off-line simulation.
2. Enhance the robustness of the DTS system. An algorithm for signal compensation is developed to eliminate the signal fluctuation due to disturbance from the hardware and its working environment. It ensures robustness of the system in industrial environments and applicability to different system configurations.
3. Improve the accuracy of the DTS system. A calibration algorithm based on cubic spline fitting is developed to cope with non-uniform fibre loss in the system, which greatly improved the accuracy of the temperature decoding in real applications with unavoidable nonlinear
characteristics.
The developed DTS system and the algorithms have been verified by continuous experiments for about one year and achieved a temperature resolution of 0.1 degree Celsius, a spatial resolution of 1 meter, and a maximum error of 2 degree Celsius in an optic fibre with the length of 2910 metres.

Full textAbstract:
This thesis presents an approach to modeling Multi Agent Systems (MAS). A framework and its implementation are presented as an extension to .NET. A number of definitions of agents are evaluated for the purpose of a broad understanding of the term software agent. Software agent has been defined in MAS context and its characteristics are identified and implemented. Motivation factors for building framework for MAS have been discussed. A number of existing technologies are discussed and evaluated. A number of agent systems previously developed are also being discussed in the middle part of the thesis. A model software agent has been defined and its characteristics are divided in two basic categories essential and optional. Its implementation has been distributed into different components throughout the MAS framework. Some of these characteristics are jointly implemented by a number of components and others responsibility rest on the individual components. Detail working of the MAS framework (i.e. what to do, when to do) is explained as guide to develop MAS using MAS framework. The protocols followed by the framework components to make communication possible between them are discussed at components level. The required information for developing MAS using MAS framework are also discussed. It answers the why, when and how questions in regards to using MAS framework A case study on Dynamic Truck Scheduling (DTS) system is discussed, designed and implemented using the MAS framework. DTS System has been used as a prototype application to test and evaluate the framework. DTS also represents a model problem that can be answered by using MAS; complete in-depth details about the problem statement are discussed. It also discusses the design and implementation of the solution along with the test results of the framework. Possible future expansion is presented in light of a number of limitations known of the MAS framework. The code working behind the different components of the MAS framework is given in appendices. Some important standards of XML that are used to pass information between agents and MAS framework components are also given in the format of tables.

Full textAbstract:
Research based on translation expertise, which is also sometimes referred to as translation competence, has been a growing area of investigation in translation studies. These studies have not only focused on how translation expertise may be conceptualised and defined, but also on how this expertise is acquired and developed by translators. One of the key observations that arise from an overview of current research in the field of translation expertise is the prevalence of process-oriented methodologies in the field, with product-oriented methodologies used comparatively infrequently. This study is based on the assumption that product-oriented methodologies, and specifically the corpus-based approach, may provide new insights into translation expertise. The study therefore sets out to address the lack of comprehensive and systematic corpus-based analyses of translation expertise. One of the foremost concerns of corpus-based translation studies has been the investigation of what is known as the features of translated language which are often categorised as: explicitation, simplification, normalisation and levelling-out. The main objective of this study is to investigate the hypothesis that the features of translated language can be taken as an index of translation expertise. The hypothesis is founded on the premise that if the features of translated language are considered to be the textual traces of translation strategies, then the different translation strategies associated with different levels of translation expertise will be reflected in different frequencies and distributions of these features of translated language in the work of experienced and inexperienced translators. The study therefore aimed to determine if there are significant differences in the frequency and distribution of the features of translated language in the work of experienced and inexperienced translators. As background to this main research question, the study also investigated a secondary hypothesis in which translated language demonstrates unique features that are the consequence of various aspects of the translation process. A custom-built comparable English corpus was used for the study, comprising three subcorpora: translations by experienced translators, translations by inexperienced translators, and non-translations. A selection of linguistic operationalization’s was chosen for each of the four features of translated language. The differences in the frequency and distribution of these linguistic operationalization’s in the three sub corpora were analysed by means of parametric or non-parametric ANOVA. The findings of the study provide some support for both hypotheses. In terms of the translation expertise hypothesis, some of the features of translated language demonstrate significantly different frequencies in the work of experienced translators compared to the work of inexperienced translators. It was found that experienced translators are less explicit in terms of: formal completeness, simplify less frequently because they use a more varied vocabulary, use longer sentences and have a lower readability index score on their translations, and use contractions more frequently, which signals that they normalise less than inexperienced translators. However, experienced translators also use neologisms and loanwords less frequently than inexperienced translators, which is suggestive of normalisation occurring more often in the work of experienced translators when it comes to lexical creativity. These linguistic differences are taken as indicative of the different translation strategies used by the two groups of translators. It is believed that the differences are primarily caused by variations in experienced and inexperienced translators‟ sensitivity to translation norms, their awareness of written language conventions, their language competence (which involves syntactic, morphological and vocabulary knowledge), and their sensitivity to register.
Furthermore, it was also found that there are indeed significant differences between translated and non-translated language, which also provides support for the second hypothesis investigated in this study. Translators explicitate more frequently than non-translators in terms of formal completeness, tend to have a less extensive vocabulary, tend to raise the overall formality of their translations, and produce texts that are less creative and more conformist than non-translators‟ texts. However, statistical support is lacking for the hypothesis that translators explicitate more at the propositional level than original text producers do, as well as for the hypothesis that translators are inclined to use a more neutral middle register.MA (Language Practice), North-West University, Vaal Triangle Campus, 2013

The financial requirements between fiber optic sensors and conventional sensors are gradually declining, which, despite many advatages and wide range of applicationas, has slowed down the demand for these sensors. With the demand for fiber optic sensors also grow the requirements for the parameters of these sensors. This thesis deals with distributed temperature fiber optic sensors. Non--linear phenomen in optical fibers, such as Raman scattering is used for measuring with these sensors. This scatterin was used to obtain information about temperature, which effected the optical cable under the test.

Des modèles hydrodynamiques, de complexité croissante construis à partir de réseaux de RPA, et associés à des corrélations, sont proposés pour représenter le mélange interne. Au regard des cinétiques de précipitation trois échelles d'homogénéisation doivent être appréhendées: temps de passage (quelques dizaines de minutes), temps de mélange du vortex (quelques dizaines de secondes), temps de micromélange des alimentations (quelques secondes).

A study of its hydrodynamic behavior has allowed the characterization of the forced vortex axial zone limited in the core of the tank. Several hydrodynamic models of increasing complexity have been proposed built from standard reactors network in association with correlations to represent the specificity of the internai mixing. Ln this way and regarding ail kinetics data involved in precipitation, three mixing scales has to be considered : the residence time (about ten minutes), the vortex mixing time (about ten secondes) and the supplies micromixing time (few seconds).

Full textAbstract:
Au cours de ces dernières années, plusieurs méthodes d’évaluation sensorielle dites « rapides » ont été développées dans le but de recueillir une caractérisation sensorielle d’un produit directement auprès du consommateur. Cette thèse s’inscrit dans cette mouvance en proposant la méthode des Déterminants Temporels du Liking (DTL) qui consiste à coupler la Dominance Temporelle des Sensations (DTS) à un suivi temporel de l’appréciation hédonique. Cette méthode permet d’identifier les déterminants sensoriels des préférences des consommateurs, et surtout dans quelles mesures leur temporalité impacte la dynamique de ces préférences. La méthode introduit le nouveau concept de « Liking While Dominant », consistant à calculer la note moyenne de liking pendant la dominance d’un descripteur dans un produit afin de quantifier son écart à la moyenne du liking de ce produit. La significativité et le signe de cet écart permettent de lister les déterminants sensoriels positifs et négatifs du liking.L’échelle de temporalité étudiée peut aussi bien être la prise (gorgée, bouchée…) que la succession de plusieurs prises du même produit constituant la consommation de tout ou partie de la portion. Dans le second cas, il est possible d’interroger de manière répétée le consommateur sur d’autres aspects que le liking, comme par exemple le wanting, l’état de faim ou de soif… Les déterminants sensoriels temporels de ces autres aspects peuvent alors être étudiés. La méthode DTL a également été déployée hors du laboratoire d’analyse sensorielle afin de se placer en situation naturelle de consommation, par exemple à domicile. Le concept DTL a été adapté à un spectromètre de masse à transfert de proton dans lequel est injectée dynamiquement la fraction aromatique capturée dans la cavité nasale du sujet lors de la mastication d’un aliment. Il est alors possible d’obtenir une dynamique de la perception sensorielle ainsi que les cinétiques de relargage des composés aromatiques ; les secondes devant expliquer la premièreOver the last years, so-called rapid methods for sensory evaluation have been developed to collect sensory description of products from consumers. Moving forward in this direction, this thesis proposes to pair Temporal Dominance of Sensations (TDS) with dynamic liking. This new method, named Temporal Drivers of Liking (TDL), highlights sensory drivers of consumer liking and determines how the dynamic perception can impact the hedonic response. This work proposes to compute the Liking While Dominant (LWD) score as the average liking scores given to a product while a given attribute was perceived as dominant and to look at its deviation from the mean liking score of this product. When significantly higher (resp. smaller) than 0, it denotes a positive (resp. negative) TDL.TDL method can evaluate temporality within intake (bites, sips…) but also between successive intakes in order to study perception along the consumption of the full food. In this case, other parameters can be asked repeatedly to the consumers such as wanting, state of hunger or thirst… Temporal drivers of these other parameters can be computed in the same way than the TDLs. The TDL method has also been deployed outside the sensory lab to place consumers in real-life conditions, for example at home. TDL concept has also been extended where subjects did TDS while the aromas released in their nose during mastication were simultaneously collected by a proton transfer reaction mass spectrometer. It makes it possible to collect simultaneously kinetics of sensory attributes and of active chemical compounds; the latter being expected to explain the former

Les microsystèmes ont connu un développement important ces dernières années dans le domaine de la chimie fine où la volonté est de développer des outils toujours plus compétitifs. Les microréacteurs appliqués à la synthèse offrent l’avantage d’un rapport surface sur volume de la zone réactionnelle élevé (> 100 cm-1), ce qui améliore nettement les transferts de masse et d’énergie et permet de traiter de très faibles quantités dans des conditions plus sûres et plus respectueuses de l’environnement. L’élément de base du microréacteur est souvent constitué d’un simple microcanal qu’il est nécessaire de dupliquer pour fournir le débit de production adapté à une application donnée. Ainsi, un microréacteur sera souvent composé d’une série de microcanaux disposés en parallèle et connectant un canal distributeur et un canal collecteur. Cette configuration peut entraîner une faible uniformité de la distribution de l’écoulement dans les différents microcanaux de réaction et il est particulièrement important d’optimiser la géométrie du microréacteur complet pour tendre vers une distribution uniforme des temps de séjour (DTS). Dans le cas de la synthèse électrochimique, les microcanaux sont directement gravés dans deux électrodes placées en vis-à-vis et séparées par une membrane échangeuse d’ions. Une optimisation préliminaire de la DTS au sein d’une électrode composée de microcanaux parallèles de section rectangulaire est réalisée. L’arrivée et la sortie du fluide s’effectue par l’intermédiaire de deux canaux distributeur et collecteur de section également rectangulaire, mais non constante. L’optimisation vise à déterminer une évolution linéaire optimale de la largeur de ces canaux distributeur et collecteur. Un modèle analytique basé sur des hypothèses simplificatrices permet de calculer les différentes pertes de charge ainsi que les débits dans chaque microcanal, dans le cas d’un écoulement laminaire de liquide. Les résultats obtenus sont ensuite confirmés par des simulations numériques 3-D, plus précises. Un modèle hybride combinant les simulations numériques pour les canaux distributeur et collecteur et le modèle analytique pour les microcanaux parallèles est également développé. Il permet d’augmenter la finesse du maillage dans les zones sensibles de l’écoulement, sans nécessité d’accroître les ressources informatiques (mémoire et temps de simulation). Les résultats obtenus montrent un très bon accord entre les simulations numériques 3-D, le modèle hybride et le modèle analytique. Sur un exemple de 10 microcanaux parallèles, il est montré que dans le cas de la géométrie initiale, pour laquelle les canaux collecteur et distributeur sont de section constante, des écarts de l’ordre de 50 % existent entre les débits traversant les microcanaux latéraux et centraux. Après optimisation, cet écart est réduit à moins de 0,1 %. Le modèle analytique est ensuite étendu au cas d’écoulements gazeux en prenant en compte les effets non linéaires et antagonistes de la raréfaction et de la compressibilité de l’écoulement. La raréfaction est ici caractérisée par un nombre de Knudsen compris entre 0 et 0,1 et se traduit pas des sauts de vitesse à la paroi ; les écoulements dans ce régime modérément raréfié sont alors correctement modélisés par les équations compressibles de Navier Stokes associées à des conditions de glissement du second ordre en Knudsen, en prenant en compte la géométrie tridimensionnelle des microcanaux de réaction et des canaux collecteur et distributeurThis study focuses on the optimisation, design and characterization of microreactors, of multichannel type, applied to the organic electrosyntheses of fluorinated compounds of medical interest such as the 2-Fluoro-2-Deoxy-D-Glucose (18FDG). Microsystems have known an important development these last years in the field of fine chemicals where the aim is to develop increasingly competitive tools. The microreactors applied to synthesis offer a reaction zone with high surface to volume ratio (> 100 cm-1), which significantly improves mass and energy transfers and allows treating small quantities in safer conditions and a better respect of environment. The basic element of the microreactor is often composed of a single microchannel, which is necessary to duplicate in order to provide the suitable production rate for a given application. Thus, a microreactor is often composed of a series of microchannels arranged in parallel and connecting a distributing channel to a collecting one. This configuration can result in poor uniformity of flow distribution among the reaction microchannels and it is particularly important to optimize the geometry of the microreactor in order to obtain a uniform residence time distribution (RTD). In the case of electrochemical synthesis, microchannels are directly etched into two electrodes facing each other and separated by an ion exchange membrane. A preliminary optimisation of the RTD in an electrode composed of parallel microchannels with rectangular cross-section is performed. The fluid inlet and outlet are connected to a distributing and a collecting channel with non constant rectangular cross-section. The aim of the optimisation is to determine an optimal linear evolution of the width of the distributing and collecting channels. An analytical model based on simplifying assumptions allows calculating the various pressure drops and the flowrate in each microchannel, in the case of a laminar liquid flow. The obtained results are then confirmed by more accurate 3-D numerical simulations. A hybrid model combining numerical simulations for the distributing and collecting channels and the analytical model for the parallel microchannels is also developed. This model allows a more refined mesh in the sensitive areas of the flow, without requiring additional numerical effort (memory and simulation time). The results show a good agreement between the 3-D numerical simulations, the hybrid model and the analytical model. On an example of 10 parallel microchannels, it is shown that in the case of the initial geometry (with a constant cross-section of collecting and distributing channels), the flowrate difference through the lateral and the central microchannels is in the order of 50%. After optimization, this difference is reduced to less than 0.1%. The analytical model is then extended to the case of gas flows, taking into account nonlinear and antagonist effects of rarefaction and compressibility. Rarefaction is characterized by the value of the Knudsen number which remains lower than 0.1; the flow in this moderately rarefied regime is accurately modelled by the compressible Navier-Stokes equations associated with second-order slip boundary conditions, taking into account the three-dimensional geometry of the reaction microchannels and of the collecting and distributing channels

Full textAbstract:
La pollution odorante est une problématique majeure, deuxième source de plaintes après le bruit. La réduction des émissions d'odeurs est incontournable, contraignant le plus souvent les industriels à la mise en œuvre d'un procédé de traitement performant et économiquement acceptable. Parmi les techniques disponibles, les procédés biologiques en général et la biofiltration en particulier sont les plus utilisés à l'échelle industrielle. Les performances de ce procédé sont étroitement liées aux paramètres opératoires. Le matériau support apparaît comme un élément clé. Du fait des critères qu'il doit satisfaire, son choix est difficile et reste encore empirique. Ces travaux de thèse visent par conséquent à rationaliser le choix d'un matériau en s'intéressant plus particulièrement à la relation entre les caractéristiques physico-chimiques et hydrodynamiques du matériau support et les composantes macroscopique et microscopique du procédé. Trois matériaux modèles ont été sélectionnés : deux granulaires et un fibreux différant par leur propriétés physico-chimiques et hydrodynamiques. Les travaux ont été menés sur des unités pilote alimentées par un effluent gazeux contenant un mélange de trois composants volatils différant par leur solubilité et leur biodégradabilité. Si une influence des caractéristiques physico-chimiques du matériau a bien été observée, il n'a pas été possible de mettre en évidence un effet des propriétés hydrodynamiques. Concernant la composante microbiologique, le niveau de diversité global est similaire, quel que soit le matériau considéré. L'analyse de la structure de la communauté bactérienne totale met en évidence trois communautés distinctes, chacune étant associée à un matériau support. Il est fort probable que la communauté endogène participe largement à l‘établissement de ces communautés, rendant ainsi plus difficile de répondre aux questions posées. La communauté bactérienne totale ne semble donc pas être un indicateur adapté. Par le suivi de la communauté fonctionnelle, des réponses plus précises pourraient être apportées. Par conséquent, la recherche de niches écologiques spécifiques à la dégradation biologique d'un composé soufré (DMS) a fait l'objet d'une attention particulière dans le cadre de cette thèseOdour nuisance is a major issue, second cause of complaints after noise. Reduction of odor emissions is essential, binding the industry to implement a process for an economically acceptable treatment in terms of reduction of odours. Among the available techniques, biological ones and particularly biofiltration are the most used on industrial scale. The performances of this process are closely related to operating conditions. Packing material appears as a key factor, its choice is difficult and remains empirical because of the multiple criteriait must satisfy. This thesis work aimed to streamline the selection of a material with a focus on the relationship between physico-chemical and hydrodynamic caracteristics of the packing material and macroscopic and microscopic components of this process. Three materials were selected as models: two granulars and one fibrous differing in their physico-chemical and hydrodynamic caracteristics. The work was carried out on pilot units fed by an effluent gas containing a mixture of three volatile components differing in their solubility and biodegradability. The influence of physico-chemical characteristics of the packing material on the performances seems to be confirmed. However, the impact of the hydrodynamic characteristics of the material on these criteria has not been demonstrated. Regarding the microbiological component, the overall level of diversity is similar, regardless of the material considered. Analysis of the structure of the total bacterial community reveals the existence of three distinct communities, each associated with a carrier material. It is likely that the endogenous community participates largely to the establishment of these communities, making it difficult to give appropriate answers to the questions adressed. The total bacterial community does not seem to be a suitable indicator. By monitoring the functional community, more precise answers could be given. Therefore, the research for specific ecological niches in the biological degradation of a sulfur compound (DMS) has been the subject of special attention in the context of this thesis

Full textAbstract:
Content:
Different tanning materials endow leather with varying colors observable in undyed leathers. Periodateoxidized starch tanned leathers have a yellow tinge or light brown color and get darker with age. The color change in situ is ascribable to iodate ions that are byproducts of periodate oxidation. Iodate ions undergo reduction to form iodine molecules that are yellow or brown in low or at higher concentrations. This study focuses on the removal of iodate ions from Dialdehyde Tapioca Starch (DTS) using a simple precipitation method. Preparation of DTS is by periodate oxidation and precipitation of iodate ions using an inorganic precipitant. The experiments for manufacturing wet-white leathers used pickled goatskins and DTS (unmodified and modified) tanning agents at various percentages based on pelt weight. Glutaraldehyde (GTA) tanning was the control. The percentage removal of iodate ions in modified DTS was 98%. Both unmodified and modified DTS had an aldehyde content of 70%. FT-IR and 1H-NMR confirmed the aldehyde groups. GTA, unmodified, and modified DTS tanned leathers had shrinkage temperatures of 80, 87, and 89°C, respectively. The physico-mechanical properties of the control and experimental leathers are comparable. GTA tanned leather had the typical brown color associated with GTA tannages. The ‘b’ color value of unmodified DTS tanned leather was high confirming yellowing of leathers upon ageing. Wet-white leather tanned with modified DTS had no discernible color change. Analysis of the spent tan liquor shows a reduction in the BOD, COD, TS, and TDS load when compared to GTA tanning system evincing the biodegradability of DTS. This study has overcome the drawback associated with periodate-oxidized starch tanning agents, viz. leather darkening over time, considering the chemical and physico-mechanical properties of the resultant leathers. The novel iodate free DTS can be scaled-up for commercial availability.
Take-Away:
Removal of iodate ions from periodate-oxidized starch before its use as a tanning agent is imperative to avoid leather color change over time.
This study reports the successful removal of iodate ions from Dialdehyde Tapioca Starch (DTS).
Wet-white leather tanned with the modified DTS had no observable color change upon ageing.

Full textAbstract:
L’appréciation par le consommateur d’un produit alimentaire comme le chocolat est en grande partie due à sa composante aromatique. La perception de cette composante est étroitement liée à la libération des composés d’arômes lors de la consommation du produit. Une étude sensorielle systématiquement menée par la société Valrhona dans une démarche de qualification de ses chocolats noirs de pures origines, fabriqués selon un procédé standard à partir de lots de cacao différents, permet de classer ces chocolats, selon leur profil, en quatre grands pôles sensoriels. Le travail entrepris avait pour but la compréhension de l’origine de cette classification sensorielle par la mise en œuvre de techniques de caractérisation des molécules volatiles responsables de l’arôme des chocolats.Dans un premier temps, l’empreinte globale en composés volatils d’un lot de 206 chocolats représentatifs des quatre pôles sensoriels a été obtenue via une méthode d’analyse couplant un headspace dynamique à la spectrométrie de masse en injection directe, utilisant l’ionisation par transfert de protons (PTR-ToF-MS). Des analyses multivariées des données, et notamment une analyse discriminante de type PLS-DA, ont permis d’élaborer un modèle de prédiction de la classification sensorielle des chocolats basé sur leur composition en molécules volatiles. Différentes méthodes de sélection de variables ont permis de souligner l’existence de composés volatils particuliers capables de discriminer les quatre pôles sensoriels de chocolats.Le potentiel aromatique de 12 chocolats parmi les 206 (trois de chaque pôle) a ensuite été déterminé suite à l’extraction des arômes par une méthode de distillation sous vide dans une analyse par chromatographie en phase gazeuse couplée, d’une part, à l’olfactométrie (GC-O) basée sur la fréquence de détection obtenue par 12 juges, et d’autre part, à un spectromètre de masse (GC-MS) pour l’identification des composés odorants. Ainsi, des composés d’arômes permettant de discriminer les différents pôles sensoriels ont pu être caractérisés au moyen d’une analyse factorielle des correspondances.Enfin, l’analyse « nosespace » d’un jury de 12 personnes dégustant 8 chocolats (deux de chaque pôle parmi les 12 précédents) a été réalisé en PTR-MS. Cette étude, couplée à une analyse sensorielle temporelle (Dominance Temporelle des Sensations, DTS), a permis d’obtenir des données temporelles instrumentales et sensorielles de manière simultanée. L’analyse DTS révèle dans une analyse en composantes principales (ACP) une bonne discrimination des pôles sensoriels, avec des descripteurs dominants similaires dans les pôles 1 et 4, d’une part, et dans les pôles 2 et 3, d’autre part. L’analyse nosespace a permis le suivi de la libération en temps réel de 26 composés d’arômes. La relation entre les deux jeux de données (instrumentales et sensorielles) a été étudiée au moyen de l’indice AWD (Abundance While Dominance) qui représente l’abondance de chaque ion pendant qu’une sensation est dominante. Des analyses factorielles des correspondances menées sur les AWD ont permis pour chaque échantillon de déceler des relations entre composés d’arômes libérés et sensations dominantesConsumers’ appreciation of chocolate is mostly due to its aromatic composition. Perception of this component is clearly linked to the release of aroma compounds during chocolate consumption. A systematic sensory evaluation is conducted by the Valrhona Company in order to qualify their pure origin dark chocolates manufactured according to a standard process from differing cocoa batches. The obtained sensory profiles allow classifying the chocolates into four sensory categories, named poles. The objective of the present work was to understand the molecular origin of this sensory classification by using techniques aimed at characterizing volatile organic compounds (VOC) responsible for chocolate flavour.Firstly, global VOC profiles of a set of 206 chocolate samples classified in the four sensory poles were analysed by a direct injection mass spectrometry method using proton transfer reaction as ionisation process (PTR-ToF-MS). A supervised multivariate data analysis based on discriminant analysis of the PLS-DA type allowed the construction of a classification model that showed excellent prediction capability based on VOC composition of the chocolates. Variable selection using dedicated methods pinpointed some volatile compounds important for the chocolates sensory discrimination.Then, the aroma potential of 12 chocolate samples (chosen among the 206 ones with three samples representative of each pole) was investigated on aroma extracts obtained by distillation under vacuum. Gas chromatography coupled to olfactometry (GC-O) and to mass spectrometry (GC-MS) was used to detect and identify the odorous compounds. GC-O data were obtained by 12 assessors using the detection frequency method. Aroma compounds allowing the discrimination of the sensory poles were determined thanks to a correspondence analysis.Finally, a nosespace analysis conducted by 12 assessors on 8 chocolates (two in each pole among the preceding 12) was realised using PTR-MS. This analysis was conducted simultaneously with a temporal sensory analysis (Temporal Dominance of Sensations, TDS), allowing temporal instrumental and sensorial data to be obtained. A principal component analysis (PCA) conducted on the TDS data revealed a good discrimination of the sensory poles, with similar dominant attributes in poles 1 and 4, on the one hand, and in poles 2 and 3, on the other hand. The nosespace data displayed real time release curves of 26 aroma compounds. The relationships between instrumental and sensory data were investigated thanks to the AWD (Abundance While Dominance) index that measures the abundance (area under the curve) of each ion during the dominance of a given sensation. Correspondence analyses of the AWD indices conducted for each chocolate sample allowed to define some relationships between dominant sensations and some released aroma compounds

Ce travail porte sur l'étude de fours tournants équipés de releveurs. Ce sont des contacteurs gaz/solide largement répandus dans de nombreux secteurs industriels mettant en oeuvre des solides divisés. Cependant en raison d'une faible connaissance du fonctionnement de ces équipements notamment en matière d'écoulement ou de transfert thermique, leur utilisation repose encore beaucoup sur le savoir faire des opérateurs acquis avec le temps. Ainsi ce travail vise à fournir aux ingénieurs des outils de connaissance et d'extrapolation pour les accompagner dans les phases de dimensionnement, mais aussi d'optimisation de procédés existants, en particulier pour des fours tournants en chauffage indirect et équipés de releveurs. La première partie de cette étude porte sur l'influence des conditions opératoires sur l'hydrodynamique des solides divisés de forme et taille différentes. Pour ce faire, des procédures expérimentales pour la mesure de distribution des temps de séjours des particules solides ont été mises en oeuvres. Deux pilotes de four tournant ont été utilisés. Ces derniers ont un ratio longueur sur diamètre équivalent mais un ratio de taille de 2. L'hydrodynamique des fours a été caractérisée quantitativement à partir des résultats expérimentaux en terme de temps de séjour des solides, taux de remplissage du four ainsi que de la dispersion axiale des particules. Ces derniers ont été modélisés par analyse dimensionnelle dans un souci de généralité en prenant en compte la présence d'éléments internes (releveurs, grille) ou diaphragmes en sortie, mais aussi des paramètres opératoires tels que la vitesse de rotation du tube, son inclinaison ou le débit des particules solides. La seconde partie de cette étude s'intéresse aux processus de transfert thermique dans les fours tournants en chauffage indirect et équipés de releveurs. Cette étude repose sur la mesure des profils de température à la paroi, dans la phase gazeuse et le lit de particules solides. L'analyse de ces profils de température se focalise sur la détermination des coefficients de transfert de chaleur entre la paroi et le lit de solides d'une part, et entre la paroi et le gaz d'autre part. Une méthode d'analyse globale de système mince et un bilan global intégrant la puissance fournie pour la chauffe sont utilisés pour la détermination de ces coefficients de transfert. Les résultats obtenus permettent d'une part de mettre en évidence l'effet des releveurs ainsi que l'influence des paramètres opératoires sur ces coefficients de transfert de chaleur et d'autre part d'établir par analyse dimensionnelle des modèles pour ces derniers. Enfin, ce travail se termine par la mise en place d'un modèle dynamique simplifié de four tournant en chauffage indirect permettant la détermination des profils de température le long du four et pouvant être facilement adapté à divers procédésThe present work addresses a fundamental study on flighted rotary kilns. They are gas-solid reactors, used in a variety of industries to process heterogeneous media. However, operating these kilns mainly relies on the know-how of operators due to insufficient fundamental understanding. The aim of this work is to provide engineers with relevant tools and models to assist in the design stage and the performance improvement of existing operating process units, in particular indirectly heated rotary kilns, inclined and equipped with lifters. In the first part, we studied the effects of operating parameters on the flow of materials of differing properties and shape. For this purpose, residence time distribution measurements were performed through experimental stimulus response tests. Two pilot-scale rotary kilns with similar length-to-diameter ratios, but a dimension ratio of about two were used in this study. We focused on the effects of lifter shape and configurations. The effects of the rotational speed, the kiln slope, the mass flow rate and the exit dam height were also analyzed. The flow of solids was quantitatively characterized primarily by the experimental mean residence time, hold-up, and axial dispersion coefficient. Using a dimensional analysis, models were established to predict the mean residence time, the filling degree and the axial dispersion coefficient, providing basic information on the kiln design, solid particle properties and operating conditions. In the second part, we studied the heat transfer mechanisms occurring in the flighted rotary kiln by measuring temperature profiles at the wall, the freeboard gas and the bulk of solids. Analysis of the temperature profiles focused on two main issues: assessment of the heat transfer coefficient between wall and gas, and assessment of the heat transfer coefficient between wall and solid particles. The lumped system analysis and a heat balance using the power supplied for the heating were applied to determine the experimental heat transfer coefficients. The effects of operating conditions and lifting flights were analyzed. Both heat transfer coefficients were then correlated through dimensional considerations. Lastly a global dynamic model mainly based on the models developed in this study can be used to determine wall, gas and bulk solids axial temperature profiles in an indirectly heated flighted rotary kiln. This global model needs to be completed with specific models related to a reaction so as to be used as a framework for the simulation of specific industrial rotary kilns

Full textAbstract:
L'objectif principal de ce travail de thèse concerne l'étude de l' élimination de la DCO et de la nitrification dans une nouveau lit bactérien Multi-Section ( MSB ) . Après une caractérisation de l’hydrodynamique et du transfert d’oxygène de ce lit bactérien, les expériences biologiques menées sous des conditions opératoires contrastées (fortes et faibles charges organiques eteaux usées contenant ou pas des matières particulairs) ont été menées. En parallèle, des simulations avec le logiciel Biowin® ont été réalisées. Les principaux résultats sont résumés en suivant :- La rétention de liquide statique est majoritaire par rapport à la rétention dynamique que ce soit en présence ou en absence de biofilm. Le biofilm joue le rôle d’une "éponge" permettant un maintien de l’humidité du lit même à faible débit. Les expériences de DTS ont montré que le biofilm accroit le temps de séjour du liquide et conduit à une diminution de l’épaisseur du film liquide permettant ainsi de promouvoir le transfert de l'oxygène.- Le réacteur MSB montre une élimination efficace de la DCO (> 95 % ) et de la nitrification ( > 60 % de l’azote entrant), mais une accumulation de DCO particulaire a lieu dans le filtre ce qui conduira à un colmatage à terme. La nitrification cohabite avecl’élimination de la DCO même dans la première section et pour une charge organique élevée ce qui implique une bonne capacité d’oxygénation du MSB par l’aération naturelle.- Un modèle dynamique de MSB a été utilisé implémenté sur le simulateur - BioWin , afin d'obtenir la répartition des biomasses au sein du réacteur et d'évaluer le processus limitant dans chaque section. Le modèle partiellement calibré peut aider à estimer les besoins minimum d'oxygène pour la nitrification et peut rendre compte de la compétition entre la croissance hétérotrophe et la nitrificationThe main objective of this PhD work focused on the study of the COD removal and nitrification in a new designed Multi-Section Bioreactor (MSB). Hydrodynamic characterization of the reactor, biological experiments under contrasted conditions and simulations by Biowin® software were carried out:- Firstly, it was found that static liquid retention is the predominant part both without and with the presence of biofilm. Biofilm acts like a "sponge". RTD experiments showed that biofilm can promote liquid residence time, decrease the liquid film andpromote the oxygen transfer consequently.- Secondly, the MSB operated at contrasted organic loading rate (OLRs) and nitrogen loading rate (NLRs) showed that COD can be effectively removed (removal efficiency > 95%) and nitrification (> 60% of the N removal) occurred in this biofilter.Nitrification is efficient even in the first section implying no drastic oxygen limitation though only natural aeration is occurring.- Thirdly, a TF dynamic model has been used from a simulator - BioWin, in order to get more insights on the biomass distribution in the pilot and to assess the limiting process in each section of the bioreactor. Calibration of the model can help us to estimate theminimum oxygen requirement for nitrification for each zone inside the pilot and it can well represent the competition between heterotrophic growth and nitrification

Uppsatsen redogör för översättningen av en novell skriven av Stephen King. Förutsättningar för vald översättningsprincip är polysystemteori, deskriptiv översättningsvetenskap, tänkt målgrupp och resultatet av en stilanalys av källtexten där en riklig förekomst av bildspråk tydliggjordes. En analys av bildspråk i måltexten visade på en övervägande adekvansinriktad översättningsstrategi och på Stephen Kings status i målkulturen som hög snarare än låg. Problem under översättningsprocessen var främst översättningen av bildspråk.This study deals with the translation of a short story written by Stephen King. Prerequisites for the selected translation principle were polysystem theory, descriptive translation studies, intended audience, and the result of a style analysis of the source text in which an abundance of imagery was clear. An analysis of the imagery in the target text found that a predominantly adequacy-oriented translation strategy was used and that Stephen King's status in the target culture can be viewed as high rather than low. Problems during the translation process were mainly associated with the translation of imagery.

Full textAbstract:
This thesis examines the trans-border circulation and production of feminist knowledge through translation. More specifically, my research focuses the translation of the U.S. women’s health book, Our Bodies, Ourselves, by a Chinese feminist NGO in 1998. My dissertation studies the social, cultural and political aspects of feminist translation, and examines the relation between translation and feminist praxis. Through the lens of gender and (feminist) health politics in 1990s China, I examine how the 1998 Chinese translation conveys the book’s message about how women should relate to their bodies.
Set in the context of Chinese society opening up during the late 1970s, my research outlines the emergence of gender awareness in China with the influx of translated feminist texts, especially in the realm of women’s health research. Medical discourses were then assigned a privileged position in the studies of women’s sexual and reproductive health. However, with increased communications between Chinese and foreign feminists, Chinese women scholars developed new ideas around women’s sexual and reproductive health. The Chinese translation of OBOS addresses the lack of gender awareness in local discussions about women’s health.
With a multi-method study, I emphasize the social and linguistic dimensions of translating a feminist health project into post-reform China. This study is based on both interview and comparative textual analysis data. Using feminist translation theories, I examine how the Chinese translators handled the book’s presentation of women’s sexuality and reproductive health. This thesis also highlights the constraints on translating feminism from the local context. This raises questions about the power of (feminist) translation, and emphasizes the need to examine the social-political context of translation practices.

Full textAbstract:
This thesis aims to elucidate the translation process by devising a way of retrieving evidence of this process from its output. It further aims to assess the claims made by some scholars concerning the possible existence of Translation Universals. In order to isolate the interaction of texts and contexts, a corpus of American short stories was created, with their translations into Persian published after the 1979 Revolution. Three complementary methodologies gave a rounded picture: (1) Corpus-based Descriptive Translation Studies; (2) The pragmatic and rhetorically-based approach of Thinking Translation devised at St Andrews; and (3) The analytical framework mostly established by Halliday in his Systemic Functional Grammar. Approaching the process of translation in the specific order devised in this thesis provided four vantage points to analyse the data in a systematic way from linguistic, discourse, cultural and literary views before reaching what are at once the most personal and most characteristic aspects of a translator's work. The research begins with a literature review of the field and an account of linguistic constraints and of all Translation Universals hypothesised so far, followed by an extensive analysis of data in two consecutive chapters. With reference to the choices made in this corpus, it is discussed in the Conclusions chapter that most of the Translation Universals so far claimed are not in fact universal. It is the role of the translator which has emerged as the determining factor in producing a translated text, and thus as the key to resolving the issues explored in this thesis. It seems there are no constraints beyond the translator's reach, and there are no parameters which do not involve the translator, who introduces his or her own choices, or manipulates certain parameters. Only when they have done so, will the translation, as both process and product, be accomplished.

Full textAbstract:
Ce travail de thèse a pour ambition d’apporter des solutions et des perspectives innovantes aux travaux de recherche actuels sur la méthanisation en voie solide, en s’appuyant sur les outils numériques. Les livrables de cette thèse s’organisent en « boîte à outils numériques » pour l’ingénieur, le chercheur et l’exploitant d’installation. Tout comme la boîte à outils de l’ouvrier, ils se structurent en plusieurs parties représentant les trois principales applications du numérique pour la méthanisation : l’optimisation, la caractérisation hydrodynamique et la modélisation. Le lien entre ces parties s’articule naturellement autour d’une approche systémique identifiant les échanges entre chacune de ces parties afin d’en former une solution complète dépassant leur somme. Ce travail a été réalisé autour de deux substrats : le fumier bovin pailleux et la tonte d’herbe, mais a été réalisé dans un esprit de transposition à tout autre substrat. La première étape de ce travail a été la conception des réacteurs et compteurs de gaz permettant de réaliser chacune des parties ultérieures à moindre coût. Ce matériel a été conçu par ordinateur après avoir déterminé les caractéristiques nécessaires par le calcul. La seconde étape a été d’utiliser une approche différente des plans d’expériences afin d’accroître l’efficacité des optimisations réalisées à l’aide de cet outil. Cette approche permet d’optimiser à la fois la composition de chaque substrat et la valeur de différents paramètres opératoires en un seul plan d’expériences combinant plans factoriels et plans de mélanges. L’outil du Bootstrapping a été également utilisé afin de minimiser les expériences réalisées en conservant la même significativité des résultats obtenus. Dans cette étude, la composition de deux substrats et deux paramètres opératoires ont été étudiés pour maximiser la production de méthane : la composition en fumier bovin et en tonte d’herbe, l’immersion du massif solide et la fréquence de recirculation de la phase liquide. La problématique de percolation est également un sujet d’étude : à quoi cela sert-il d’optimiser les paramètres opératoires si la phase liquide ne peut percoler au sein du massif solide ? La troisième étape de ce travail réside dans l’étude de l’écoulement de la phase liquide au sein d’un massif en conditions de codigestion en fonction de sa composition et de sa stratification. Cette étape permet de fournir des paramètres caractéristiques de l’écoulement, de proposer une nouvelle approche de la stratification et de mettre en évidence l’effet de la codigestion sur l’évolution des microporosités et macroporosités. Enfin, l’impact de l’évolution des microporosités et macroporosités sur la biologie a été injecté dans un modèle à un seul substrat afin de fournir un outil de compréhension du phénomène et un premier pas vers la prédiction du phénomène. L’ensemble de cette démarche permet donc d’optimiser les paramètres opératoires, de s’assurer de l’aspect fonctionnel d’une expérience et de proposer un modèle de compréhension globalisant les connaissances. Ce n’est pas une solution définitive mais une solution à étayer, tout comme la boîte à outils se renouvelle en outils toujours plus performantsThis work aims to provide innovative solutions and perspectives to the current research work on solid state anaerobic digestion, using digital tools. The deliverables of this study are organized into a “digital toolbox” for engineers and researchers. Like the worker’s toolbox, this solution consists of several sections representing the three main digital applications for anaerobic digestion: optimization, hydrodynamics and modeling. Each part is linked with others to build a systemic approach identifying exchanges between them in order to form a complete solution exceeding the sum of its parts. This work was carried out around two substrates: straw cattle manure and damp grass. It was however designed to be transposed to any substrates. The first step in this work was the reactors and gas counters conception to perform each of these steps at lower cost. This equipment was computer-aided designed after the characteristics were determined by calculation. The second step was to determine a different approach from experimental designs to increase the optimization efficiency using this tool. This method allows tooptimize both the composition of each substrate and the different operating parameters values in a single experimental design combining factor design and mix design. The bootstrapping tool is also used to minimize the number of experiments while maintaining the results significance. In this study, the two substrates composition and two operating parameters were studied to maximize methane yield. The two substrates were cattle manure and damp grass, and the two studied parameters were immersion of the substrates and recirculation frequency of the liquid phase. The percolation is also a study subject: what is the purpose of optimizing the operating parameters if the liquid phase cannot percolate within the solid part? Therefore, the third step of this work is to study the liquid phase flow within the solid part under codigestion conditions according to its composition and stratification. This step allows to provide the flow characteristic parameter to propose a new stratification approach and to highlight the codigestion effect on the microporosity and macroporosity evolution. Finally, the microporosity and macroporosity evolution impact on biology was modeled in a single substrate model to provide an understanding tool and a first work step on a prediction tool integrating these phenomena. The whole study allows to optimize the operating parameters, to ensure the functional aspect of an experiment and bring forward an understanding model of porosities evolution. It is not a definitive solution but a solution to substantiate, just as the toolbox is continuously renewed in innovative and more efficient tools

Full textAbstract:
I denna magisteruppsats undersöks Julia Donaldsons engelska bilderböcker i svensk översättning av barnboksförfattaren Lennart Hellsing. Huvudsyftet med denna studie är att avgöra om de svenska måltexterna även bär drag av Hellsings egen författarstil. För att kunna undersöka detta har Kårelands tidigare forskning (2002) om Hellsings litterära produktion använts för att ta fram stilvariabler. Dessa stilvariabler har sedan applicerats på måltexterna i denna fallstudie. Det teoretiska ramverket orienterar sig inom deskriptiv översättningsvetenskap och Tourys (1995) modell för rekonstruktion av översättningsnormer används. Detta möjliggör placerandet av källtexter (KT) och måltexter (MT) i en sociokulturell kontext. I den deskriptiva analysen jämförs KT med MT och översättning som begrepp förstås som något som omgärdas av översättningsnormer vid en viss tidpunkt och inom en viss kultur. Resultaten visar att Hellsings stil som författare återfanns i de översatta texterna och resultaten pekar även mot att översättningen av dessa texter kan ses som en acceptansinriktad praktik.This master’s thesis looks at the translation of Julia Donaldson’s English picture books into Swedish by the Swedish children’s author Lennart Hellsing. The main aim of the study is to determine whether the translation of the original (source) texts involves the transference of Hellsing’s writing style into the translated (target) texts. Earlier research, carried out by Kåreland (2002), is employed in order to pinpoint Hellsing’s distinctive style as a writer. The style variables apparent in Hellsing’s own writing were thereby identified and these are applied to the analysed target texts in this case study. The theoretical framework is based on descriptive translation studies (DTS) and the use of Toury’s model (1995) for reconstructing translational norms allows the source texts (ST) and target texts (TT) to be put into a sociocultural context. By working within this framework a descriptive analysis is used to describe and compare the ST and TT and the concept of translation as a practice governed by certain translational norms at a certain moment in time and within a certain culture is applied. The findings show that Hellsing’s style as a writer can also be detected in his translations of Donaldson’s picture books. The results of this case study also indicate that the translation of these texts can be considered to be a target culture oriented practice.

Full textAbstract:
Detta arbete behandlar en specifik typ av överbelastningsattack som blir allt mer populär. Dessa attacker utförs genom öppna reläer med syftet att få ut en avsevärt mycket högre effekt än den som annars är uppnåbar. Granskning av attacker utförda genom tjänsterna DNS och NTP har utförts med syftet att ge en klar bild av hur allvarligt hotet är och även klargöra hur en systemadministratör kan säkra tjänsterna för att skydda både sina egna och andras resurser. Resultaten av undersökningar visar att en attack utförd genom en DNS-tjänst ger under optimala förhållanden en amplifikationsfaktor av "102.4" och en attack genom en NTP-tjänst ger under optimala förhållanden en amplifikationsfaktor av "229.16". Resultaten visar även att problemet kan lösas helt eller delvis genom att begränsa tillåtna nätverk eller stänga av rekursion i DNS och kommandon i NTP.This work concerns a specific type of Denial of Service attack which is becoming increasingly popular. These attacks are carried out through open relays with the purpose of getting a significantly higher effect than otherwise achievable. Examination of attacks carried out through the services DNS and NTP have been conducted with the purpose of providing a clear picture of how serious the threat is and also clarify how a system administrator can secure the services to protect both their own and others resources. The results of our studies show that an attack performed through a DNS service gives under optimal conditions a amplification factor of "102.4" and an attack through a NTP service gives under optimal conditions a amplification factor of "229.16". The results also show that the problem can be solved in whole or in part by limiting the allowed network or disable recursion in DNS and commands in NTP.

Essa pesquisa é fruto do diálogo entre os campos de saberes da Sexualidade e da Saúde Mental. Nosso objetivo foi compreender a interface entre loucura e sexualidade nos discursos dos profissionais dos SRTs da cidade do Recife. A partir do referencial epistemológico do construcionismo social que nega as versões naturalizadas e universalizadas de realidade, compreendemos loucura e sexualidade como contructos sociais. Para analisar os dados coletados, utilizamos a Análise Crítica do Discurso, cujo foco de atenção recai sobre as dinâmicas das relações de poder que engendram os discursos. Como procedimentos de coleta, recorremos à entrevista semi-estruturada com 09 profissionais dos SRTs - analisamos apenas 06 -, ao diário de campo e à observação no SRT feminino no momento da coleta. Observamos avanços na política de desinstitucionalização no que se refere à implantação dos SRTs, uma vez que as casas localizadas na própria comunidade possibilitam a esses moradores, antes hospitalizados, um acesso a condições mínimas de dignidade. No eixo clínico, as ações de reabilitação psicossocial parecem focalizar os cuidados básicos com o corpo e com a casa, por meio de condutas pautadas pela palavra, pela escuta, pelo afeto e pelo acompanhamento direto a essas atividades da vida diária, promovendo uma mudança significativa na conformação desses corpos. No entanto, identificamos que o cuidado precisa ser ampliado na direção da acolhida da história desses corpos que trazem profundo sofrimento por terem suas sexualidades interrompidas e violentadas pela institucionalização psiquiátrica. Percebemos que os discursos sobre as expressões de sexualidade desses moradores e moradoras ora apresentam características da institucionalização, como infantilização, silenciamentos e condutas de tutela, assentados em padrões de gênero pautados na moral sexual cristã; ora, são discursos de reconhecimento dessa sexualidade como uma dimensão importante da vida desses sujeitos e que, portanto, precisa ser pensada pela equipe. Identificamos fragilidades no campo da conscientização dos direitos sexuais e dos direitos reprodutivos como elementos importantes no modelamento da atenção e dos modos de cuidar da equipe e, ainda, na compreensão da sexualidade desses moradores e dessas moradoras como um direito a ser garantido. Ainda nesse campo, encontram-se dificuldades de acesso à rede de serviços voltados para saúde do homem e da mulher. Diante disso, pensamos que a Reforma psiquiátrica precisa contemplar, em seu processo de inversão do modelo de atenção em saúde mental, uma pauta de ação que contemple o lugar de sentido da questão da sexualidade dos moradores e das moradoras dos SRTs, a fim de cuidar de uma dimensão de suas vidas há muito negligenciada pelas políticas públicas de saúde, promovendo, com isso, a autonomia e a cidadania.
This research emerges from the dialogue between Sexuality and Mental Health. We aimed at understanding the interface between madness and sexuality in the discourse of RTSs (Residential Therapeutic Servants) from Recife. Based on the epistemological grounds of social constructionism which denies naturalized and universal versions of reality, we understand madness and sexuality as social constructions. To analyze the collected data, Critical Discourse Analysis was used, focusing on the dynamics of power relations that articulate discourses. We discussed issues regarding the psychiatrization of madness, reviewing devices of body control and sexuality of mad individuals leading to the Psychiatric Reform in its Deinstitutionalization. Next, we explained some aspects of human sexuality from Foucault to Sexual and Reproductive Rights in its articulation to Mental Health. Research was conducted in the field of RTSs on qualitative approach. Data collection consisted of semi-structured interview with 09 RTS professionals – but only 06 were analyzed – field diary and observation of female RTS during data collection. We noticed advances in deinstitutionalization policies where the installation of RTSs is concerned, once the facilities located in the very community allow residents, previously committed, access to condition of minimal dignity. Clinically, actions of psychosocial rehabilitation seem to concentrate basic care on body and housing, by means of behavior modeled by speaking, listening, affection and direct support to daily activities, thus promoting significant change in the conformity of those bodies. However, we identified the necessity of extending such care towards embracing biographically the history of those bodies that carry deep suffering for having their sexualities interrupted and violated by psychiatric institutionalization. We noted that discourses on expression of sexuality from male and female residents either present characteristics of institutionalization, such as infantilization, silencing and guardianship, consolidated in patterns of gender shaped by Christian sexual moral; or are discourses of recognition of sexuality as an important dimension of these subjects’ lives and should, therefore, be taken into account by the staff. We identified fragilities in the field of awareness raising for sexual and reproductive rights as relevant elements in the modeling of attention and staff care’s attitude as well as in the comprehension of female and male residents’ sexuality as a right to be guaranteed. Also on this matter, difficulties were found in accessing healthcare service network for men and women. Bearing this in mind, Psychiatric Reform needs to embrace in the process of inverting the model of attention in mental health, a plan of action that includes the place of meaning of RTS male and female residents’ sexuality, in order to support a dimension of their lives long neglected by public health policies, therefore promoting autonomy and citizenship.

Full textAbstract:
Les échanges entre les rivières et les nappes d’eau souterraine jouent un rôle essentiel dans le maintien des écosystèmes aquatiques. Or, leur caractérisation demeure difficile du fait de leur forte variabilité dans l’espace et dans le temps. Dans ce contexte, l’objectif de ce travail de thèse est de développer des méthodes actives de mesures distribuées de température pour quantifier la dynamique des interactions nappe/rivière. Après avoir établi une nouvelle approche pour évaluer la résolution spatiale des mesures de température, nous avons validé deux nouvelles méthodes d’interprétation permettant d’estimer de manière distribuée les flux d’eau et la conductivité thermique du milieu poreux. Les travaux, associant modélisations numériques et mesures expérimentales en laboratoire, montrent que les méthodes d’interprétation développées permettent d’estimer avec une excellente précision les écoulements et que la gamme de flux pouvant être investiguée est particulièrement large. Pour tester cette approche prometteuse, des expériences actives ont ensuite été réalisées sur le terrain dans deux environnements différents : d’abord dans un petit cours d’eau d’ordre 1 de tête de bassin versant, puis dans un fleuve s’écoulant le long d’une plaine alluviale. Ces applications ont démontré le fort potentiel des méthodes actives pour quantifier les écoulements à l’interface nappe/rivière et décrire leur variabilité spatiale et temporelle. La comparaison des résultats obtenus sur les deux sites a permis finalement de discuter la faisabilité, les apports mais aussi les limites de la méthode dans différents contextes hydrologiquesGroundwater/surface water interactions play a fundamental role in the functioning of aquatic ecosystems. However, their quantification is challenging because exchange processes vary both in time and space. Here, we propose an active distributed heat transport experiment in order to quantify the spatial and temporal variability of groundwater/surface water interactions. As a first step, we proposed a new approach to evaluate the spatial resolution of temperature measurements. Then, two interpretation methods of active-DTS experiments were developed and fully validated to estimate the distribution of porous media thermal conductivity and the groundwater fluxes in sediments. Based on numerical simulations and sandbox experiments, results demonstrated the potentiality of these methods for quantifying distributed groundwater fluxes with high accuracy. The large range of groundwater fluxes that can be investigated with the method makes specially promising the application of active experiments for many subsurface applications. Secondly, we conducted heat transport experiments within the streambed sediments of two different streams: in a first-order stream, then in a large flow-system located along an alluvial plain. These applications demonstrated the relevance of using active experiments to characterize the spatial complexity of stream exchanges. Finally, the comparison of results obtained for each experimental site allowed discussing the capabilities and limitations of using active-DTS field experiments to characterize groundwater/surface water interactions in different hydrological contexts
