Resumo: Neste trabalho, estudamos o crescimento de nanofios planares de InP pelo mecanismo Vapor-Líquido-Sólido (VLS), com o objetivo de entender a dinâmica da nanopartícula metálica catalisadora durante o processo. Para isso utilizamos substratos de GaAs (111)A e o sistema de Epitaxia de Feixe Químico (CBE). O óxido nativo não foi totalmente removido termicamente antes do crescimento, com o objetivo de manter o nanofio isolado eletricamente do substrato. Como um dos objetivos do trabalho, estudamos a possibilidade de controle da direção de crescimento do nanofio planar através de diferentes tratamentos de superfície, e de modo independente da cristalografia do substrato utilizado. As amostras processadas e/ou crescidas foram caracterizadas por técnicas de microscopia eletrônica (varredura e transmissão) e microscopia de força atômica. Investigamos inicialmente como a camada de óxido influencia as direções de crescimento dos nanofios planares no substrato não tratado. Posteriormente, processamos padrões de linhas com rugosidade ligeiramente diferente da mostrada pelo substrato, utilizando técnicas como Litografia por Feixe de Elétrons (EBL), Corrosão por Feixe de Íons Focalizados (FIB) e Ataque por Íons Reativos (RIE). Os padrões gravados eram compostos por linhas perpendiculares com várias micra de comprimento e larguras de dezenas de nm. Observamos que existe uma relação direta do diâmetro do nanofio com a orientação que este assume ao chegar à região onde se encontra a linha (se segue alinhado à linha ou se a ignora; ou se muda sua orientação). Nossos resultados podem ser explicados pelas diferentes energias de superfície presentes no problema, que afetam a dinâmica da nanopartícula catalisadora. Nosso trabalho também mostra que é possível obter maior controle da orientação espacial do nanofio planar crescido, controlando o processamento da superfície e o diâmetro da nanopartícula
Abstract: In this work, we studied the growth of InP planar nanowires by the vapor-liquid-solid (VLS) mechanism, in order to understand the metallic catalyst nanoparticle dynamics during this process. In our studies, we used GaAs (111)A substrates and the Chemical Beam Epitaxy (CBE) system. The native oxide layer was not completely thermally desorbed, in order to keep the nanowire electrically isolated from the substrate. As one of the goals of this work, we study the possibility to control nanowire growth direction via different surface treatments, independently of the substrate crystallography. Our processed and/or grown samples were characterized by electron (scanning and transmission) and atomic force microscopy. We first investigated how the oxide layer influences the growth directions of planar nanowires on unprocessed substrates. Subsequently, patterns of lines with roughness slightly different from those shown by the substrate were patterned using techniques such as Electron-beam Lithography (EBL), Focused Ion-beam Corrosion (FIB) and Reactive Ion Etching (RIE). These patterns were composed of perpendicular lines with several micra in length and tens of nanometers wide. We observed that there is a direct relation between the nanowire diameter and the orientation that the nanowire assumes when it reaches the region where the line is located (if the nanowire aligns with the line or ignores it, or if its orientation changes). Our results can be explained by the different surface energies present in the problem, which affect the dynamics of the catalytic nanoparticle. Our work also shows that it is possible to obtain better control of the spatial orientation of the grown planar nanowire, by controlling the surface processing and the nanoparticle diameter

O controle de velocidade de PIGs instrumentados ? necess?rio, dentro da ind?stria de petr?leo e g?s, para permitir uma inspe??o de dutos de melhor qualidade e maior seguran?a. Isto s? ? poss?vel quando esses PIGs mant?m uma velocidade baixa durante a opera??o de inspe??o de dutos, na procura de defeitos como corros?o, trincas e amassamentos. Este trabalho tem por objetivo propor uma tecnologia para o controle de velocidade de PIGs instrumentados utilizando uma v?lvula by-pass acionada por uma solenoide. Essa v?lvula tem a capacidade de controlar o diferencial de press?o atuante no corpo do PIG. E controlar o diferencial de press?o significa controlar a velocidade desse PIG. Uma bancada de testes foi montada em escala reduzida para simula??o de situa??es de ?tiro? e de acelera??o sofridos pelos PIGs. A bancada permitiu estudar as rea??es das press?es a montante e a jusante da v?lvula by-pass. A l?gica Fuzzy foi utilizada para determinar os tempos de abertura e fechamento dessa v?lvula, com objetivo de controlar o diferencial de press?o. Os testes na bancada mostraram uma redu??o substancial no valor do diferencial de press?o atuante no PIG ap?s a ocorr?ncia do ?tiro?. Tamb?m ocorreu uma redu??o no tempo em que o diferencial de press?o vai ao m?ximo e retorna ao valor de refer?ncia predefinido. Os resultados obtidos permitem concluir que ? poss?vel controlar o diferencial de press?o atuante no PIG, assim tamb?m a velocidade, utilizando a l?gica Fuzzy, atuando na abertura e fechamento da v?lvula by-pass proposta.
The speed control of smart PIGs is necessary, in oil and gas industry, for allow a better and safer pipeline inspection. This is possible when those smart it PIGs maintain a low speed while performs a pipeline inspection, in the search for defects as corrosion, cracks and dents. Our objective propose a technology for speed control of smart pigs using a by-pass valve triggered by a solenoid. This valve is able to control the pressure differential applied in PIG ?s body. Once we control the pressure differential, it is possible to control the speed of this PIG . A experimental benchmark was mounted in reduced scale for simulation of the PIG speed excursion situation and acceleration suffered by the PIGs . The experimental benchmark allowed to studying the reactions of the upstream and downstream pressure over the by-pass valve.The Fuzzy logic was used for determine the opening and closing period this valve to control pressure differential. The experimental tests show substantial reduction in pressure differential value over PIG after happening speed excursion. Also, the time necessary for the pressure differential go to maximum and returns to default reference value. The results obtained allow conclude which is possible to controlling pressure differential applied in PIG , thus also the speed, using Fuzzy logic, acting opening and closing period of proposed by-pass valve

Na ind?stria do petr?leo s?o comumente empregados oleodutos e gasodutos para executar o transporte dos fluidos de produ??o a grandes distancias. As manuten??es desses dutos passam pela an?lise de diversas ferramentas, dentre as mais empregadas atualmente destaca-se as c?lulas de inspe??o de duto, popularmente conhecida como PIG. Dentre as variantes existentes no mercado, o chamado PIG instrumentado possui relev?ncia significativa, visto que atrav?s dos in?meros sensores existentes nele, o equipamento pode detectar falhas ou potenciais de falha ao longo da linha inspecionada. Apesar de sua versatilidade, o PIG instrumentado sofre com varia??es de velocidade, o que prejudica a leitura dos sensores embutidos nele. Como o PIG desloca-se em fun??o da velocidade do fluido de produ??o, uma forma de controlar a velocidade dele ? controlar a vaz?o deste fluido, atrav?s do controle da press?o, reduzindo a velocidade de escoamento do fluxo produzido, resultando na redu??o da produ??o total do fluido nos pr?prios dutos ou com o emprego de um elemento restritivo (v?lvula) instalado nele. A caracter?stica da raz?o vaz?o/perda de press?o de elementos restritivos do tipo orif?cio ? normalmente deduzida da equa??o ideal de energia (equa??o de Bernoulli) e, em seguida, corrigida para as perdas, normalmente por meio de testes experimentais. Assim, com o objetivo de controlar a vaz?o de um fluido que passa pelo PIG, foi desenvolvido uma v?lvula com obturador acionado por meio de solen?ide. Esta configura??o permite uma maior facilidade de controle e estabiliza??o do ajuste de vaz?o, com consequente resposta na quedas de press?o entre ? montante e ? jusante da restri??o. Para defini??o de coeficientes de vaz?o, foi montada uma bancada para realiza??o de ensaios, composta por um duto de quatro polegadas de di?metro interno, uma conjunto de obturadores dispostos em arranjo em uma placa e medidores de press?o para verifica??o de quedas de press?o no ensaio. A linha foi pressurizada e com base nas coletas de queda de press?o foi poss?vel tra?ar uma curva que caracterize o coeficiente de vaz?o do prot?tipo da v?lvula de controle e simular em bancada o funcionamento dela, resultando em redu??es de velocidade do PIG em aproximadamente 68%.
In the Oil industry, oil and gas pipelines are commonly utilized to perform the transportation of production fluids to longer distances. The maintenance of the pipelines passes through the analysis of several tools, in which the most currently used are the pipelines inspection cells, popularly knowing as PIG. Among the variants existing in the market, the instrumented PIG has a significant relevance; acknowledging that through the numerous sensors existing in the equipment, it can detect faults or potential failure along the inspected line. Despite its versatility, the instrumented PIG suffers from speed variations, impairing the reading of sensors embedded in it. Considering that PIG moves depending on the speed of the production fluid, a way to control his speed is to control the flow of the fluid through the pressure control, reducing the flow rate of the produced flow, resulting in reduction of overall production the fluid in the ducts own or with the use of a restrictive element (valve) installed on it. The characteristic of the flow rate/pressure drop from restrictive elements of the orifice plate is deducted usually from the ideal energy equation (Bernoulli?s equation) and later, the losses are corrected normally through experimental tests. Thus, with the objective of controlling the fluids flow passing through the PIG, a valve shutter actuated by solenoid has been developed. This configuration allows an ease control and stabilization of the flow adjustment, with a consequent response in the pressure drops between upstream and downstream of the restriction. It was assembled a test bench for better definition of flow coefficients; composed by a duct with intern diameter of four inches, one set of shutters arranged in a plate and pressure gauges for checking the pressure drop in the test. The line was pressurized and based on the pressure drop it was possible to draw a curve able to characterize the flow coefficient of the control valve prototype and simulate in mockup the functioning, resulting in PIG speed reduction of approximately 68%.

Resumo: Neste trabalho é apresentada a implementação de uma estratégia de controle escalar V/f que mantém o fluxo de entreferro constante em seu valor nominal a partir do controle da relação entre a tensão de terceira harmônica, do estator, presente devido à saturação magnética, e da freqüência elétrica. No caso das bobinas de estator estarem conectadas em Y, a terceira harmônica de tensão é obtida a partir da soma das tensões de fase do estator. Na. presente proposta não é necessário saber a magnitude do fluxo, mas apenas o valor da terceira harmônica de tensão quando o motor opera na sua condição nominal. O método proposto é simples de ser implementado, computacionalmente leve e insensível aos parâmetros do motor. Esta última característica é especialmente atrativa, pois boa parte cios acionamentos elétricos propostos na literatura com controle escalar tem seu desempenho insatisfatório devido à influência da variação da resistência de estator, principalmente quando o motor opera em baixas velocidades. Resultados experimentais mostram que a técnica implementada tem um excelente desempenho em regime permanente, ainda que com carga mecânica, e bom desempenho nos transitórios
Abstract: In this work it is presented the implementation of scalar control V/f technique. It keeps the air gap flux constant in its rated value by the control of the relation between third harmonic voltage, due to saturation, and electric frequency. When the coils are conected in Y. the third harmonic is obtained by the sum of staler phase voltage. We propose that it is not necessary to know the air gap flux magnitude, but only the third harmonic value when the induction motor operates in rated condition. The proposed method is easy to implement, has a light coputational processing and it is not sensitive to motor parameters. This last caracteristic is attractive, because many electric drivers have low performance due to the influence of stator resistence variation, mainly when, the motor operates in reduced speed. Experimental results show the high performance of system in steady state, with applied load, and good performance in dynamic situation

Abstract:

No mundo todo, o manejo integrado de moscas-das-frutas é feito com associação do controle biológico aplicado e técnica do inseto estéril. Além da boa eficiência no campo, a associação dessas técnicas é também favorecida pelo fato de ambos os organismos, insetos estéreis e parasitoides, poderem ser produzidos massalmente na mesma fábrica com menor custo. Visando à produção massal do parasitoide de moscas-das-frutas Diachasmimorpha longicaudata e de insetos estéreis para atender a programas de manejo integrado de Ceratitis capitata e Anastrepha fraterculus, o presente trabalho foi desenvolvido no Centro de Energia Nuclear na Agricultura (CENA), da Universidade de São Paulo, entre os anos de 2006 a 2012. Durante esse período, metodologias de criação em laboratório foram implementadas e permitiram o desenvolvimento da tecnologia necessária para a produção desses insetos em grande escala no Brasil. Dados de 25 gerações do parasitoide produzido em grande escala em C. capitata tsl-Viena 8 e 51 gerações em A. fraterculus, bem como os efeitos e diferenças desses hospedeiros na qualidade do parasitoide foram analisados. É possível criar o parasitoide D. longicaudata em ambos os hospedeiros, C. capitata linhagem tsl-Viena 8 e A. fraterculus, entretanto essa linhagem de C. capitata não é indicada para produção massal do parasitoide, pois a emergência é muito baixa devido à debilidade do hospedeiro, possivelmente acarretada pelas manipulações genéticas que permitem a sexagem da mosca na fase embrionária. Caso essa seja a linhagem com melhor custo/ benefício disponível, recomenda-se o uso de larvas hospedeiras oriundas de ovos tratados termicamente para a produção do parasitoide. A criação em grande escala de A. fraterculus foi estabelecida com sucesso após o período de domesticação da espécie, obtendo-se larvas de boa qualidade com baixo custo, devido à dieta larval com baixa concentração de ágar e total uso de ingredientes nacionais nas dietas de adultos e larvas, por mais de 50 gerações. O uso de larvas irradiadas de A. fraterculus para a produção de D. longicaudata promove maior emergência do parasitoide, com maior quantidade e melhor qualidade de fêmeas que larvas de C. capitata.
The integrated management of fruit flies is worldwide done with the association of augmentative biological control with parasitoids and the sterile insect technique. Beyond the efficiency in the field, the joint of both techniques is also favored by the easy production of organisms, both parasitoids and sterile insects, in the same facility with low costs. Aiming for the mass production of the fruit fly parasitoid Diachasmimorpha longicaudata and sterile insects to support integrated management programs for Ceratitis capitata and Anastrepha fraterculus, this work was developed at the Center of Nuclear Energy in Agriculture (CENA) of the University of São Paulo, between 2006 and 2012. Along this period, laboratory rearing methods were improved which allowed the development of the required technology for a large scale production of those insects in Brazil. Data of 25 generations of the parasitoid large scale production using C. capitata tsl-Vienna 8 strain and 51 generations using A. fraterculus as hosts are presented. Moreover, the effect and differences between hosts in parasitoid\'s quality were analyzed. The parasitoid D. longicaudata can be large scale produced using both C. capitata tsl- Vienna 8 or A. fraterculus as hosts, but this strain of C. capitata is not recommended for D. longicaudata mass production once the parasitoid emergency is very low due to the host weakness. If this strain is the best cost/benefit available, the use of host larvae originating from heat treated eggs might be considered to parasitoids production. The A. fraterculus large scale rearing was established successfully after the domestication period of the specie, producing a large amount of insects with excellent quality using local ingredients and little agar in the diet composition over 50 generations. A. fraterculus irradiated larvae as host for large scale producing D. longicaudata promotes greater parasitoid emergence with greater female biased sex ratio and better female quality than C.capitata larvae.

Agarramento em v?lvulas ? um problema muito comum em malhas de controle e geralmente ? a principal causa do mau desempenho de sistemas industriais. Os efeitos desta n?o linearidade mais comumente observados s?o oscila??es nas vari?veis de processo. Para contornar os efeitos indesej?veis, compensadores de atrito t?m sido propostos, com o objetivo de reduzir a variabilidade na sa?da. Neste trabalho ? analisada a compensa??o do atrito em v?lvulas de controle pneum?ticas por meio de uma t?cnica de lineariza??o por realimenta??o. O modelo da v?lvula utilizado inclui tanto zona morta quanto salto. Resultados de simula??o mostram que o uso desse modelo mais completo resulta em controladores com desempenho superior.

In control loops valve stiction is a very common problem. Generally, it is one of main causes of poor performance of industrial systems. Its most commonly observed effect is oscillation in the process variables. To circumvent the undesirable effects, friction compensators have been proposed in order to reduce the variability in the output. This work analyzes the friction compensation in pneumatic control valves by using feedback linearization technique. The valve model includes both dead zone and jump. Simulations show that the use of this more complete model results in controllers with superior performance. The method is also compared through simulations with the method known as Constant Reinforcement (CR), widely used in this problem.

Abstract:

L'initiation alternative de la traduction permet la synthese de plusieurs formes proteiques a partir d'un seul messager par l'utilisation alternative de plusieurs codons d'initiation de la traduction sur ce messager. Nous nous sommes interesses aux mecanismes de controle de deux systemes d'initiation alternative de la traduction: un systeme retroviral, le virus de la leucemie murine (mo-mul v), ainsi qu'un gene eucaryote superieur, le facteur de croissance fibroblastique 2 (fgf-2) humain. L'arnm gag-pol du virus mulv possede deux codons d'initiation de la traduction (1 cug, 1 aug) permettant la synthese du precurseur gag des proteines de nucleocapside et d'un antigene de surface essentiel a la dissemination et aux effets pathogenes du virus. Le taux de synthese relatif de ces deux proteines est essentiel au bon deroulement du cycle replicatif. Le travail effectue a permis de montrer que ce retrovirus contient une sequence qui confere a son arnm la capacite d'etre traduit par un mecanisme original d'entree interne des ribosomes, different du mecanisme classique d'entree du ribosome par l'extremite 5' du messager. Cette sequence est la cible du facteur d'epissage ptb qui pourrait donc etre implique dans le mecanisme. Ce processus d'entree interne permet de controler l'initiation alternative de la traduction sur ce messager en selectionnant uniquement le codon aug. L'arnm du fgf-2 humain possede quant a lui quatre codons d'initiation de la traduction (3 cug et 1 aug) permettant la synthese de quatre isoformes fgf-2 ayant des localisations subcellulaires differentes et pouvant modifier les phenotypes cellulaires de facon diverse. On peut donc penser que le controle de l'expression relative des quatre isoformes fgf-2 a un impact important sur la cellule. Les resultats obtenus montrent qu'il existe dans la partie 5' de ce messager differents elements de controle en cis de l'utilisation des quatre codons d'initiation. Un d'entre eux correspond a un site d'entree interne des ribosomes. La presence de ce site peut potentiellement permettre la synthese de fgf-2 dans des conditions de stress ou durant la mitose. Finalement, trois proteines sont capables d'interagir specifiquement avec la partie 5' non traduite de ce messager. De facon interessante, ces proteines sont trouvees dans les types cellulaires transformes analyses qui produisent les quatre isoformes fgf-2 mais pas dans les types cellulaires normaux analyses qui produisent uniquement la petite forme de fgf-2. En conclusion, cette etude laisse penser que le processus d'initiation alternative de la traduction, en plus de contribuer a l'augmentation de la diversite genique, peut reguler l'expression relative de proteines avec des fonctions differentes, mais codees par le meme gene. De plus, la demonstration de l'existence du mecanisme d'entree interne des ribosomes sur deux messagers differents permet d'envisager une generalisation de ce processus pour de nombreux messagers. Le processus d'entree interne des ribosomes semble par ailleurs etre un nouveau mecanisme de regulation traductionnelle de l'expression des genes

O estudo aborda a participaÃÃo e o exercÃcio do controle social na polÃtica pÃblica (PP) de saÃde implementada em Fortaleza, em sua regiÃo de menor IDH, a SER V, a partir de dois aspectos analÃtico-conceituais: a noÃÃo de controle social como fenÃmeno teÃrico-polÃtico e o Conselho Regional de SaÃde V como campo de pesquisa e objeto empÃrico.

Abstract:

No contexto da prevenção da infecção cruzada na radiologia odontológica, superfícies que entram em contato direto com as mãos dos profissionais, como as superfícies da câmara escura portátil, devem ser descontaminadas. A recomendação clássica da descontaminação com álcool 70% p/v após limpeza prévia, nem sempre é seguida justificada pela não praticidade, acrescida do tempo curto disponível entre um atendimento e outro, limitando-se à aplicação direta do álcool o que, a priori, contraria as Boas Práticas de Controle de Infecção. A presente investigação, de caráter experimental laboratorial, controlado, randomizado e unicegado, teve como objetivo avaliar comparativamente a eficácia desinfetante do álcool 70% (p/v) sob fricção, com e sem limpeza prévia nas superfícies de câmaras escuras portáteis como procedimento de limpeza/desinfecção concorrente em radiologia odontológica. Três grupos de estudo foram constituídos: Grupo controle: superfícies previamente contaminadas com desafio (micro-organismo teste Serratia marcescens ATCC 14756, acrescido de 10% de saliva humana), submetidas à limpeza clássica por meio de água e detergente sob fricção, e posterior enxágue e consecutivamente, desinfecção com aplicação do álcool 70% p/v. Grupo experimental: superfícies previamente contaminadas com desafio, à semelhança do grupo controle, submetidas à aplicação direta do álcool 70% p/v sob fricção, SEM limpeza prévia. Grupo controle positivo: superfícies contaminadas com desafio. O tamanho amostral para os grupos experimental e controle foi de 85 unidades. Os experimentos foram realizados no Laboratório de Ensaios Microbiológicos do Departamento de Enfermagem Médico-Cirúrgica da Escola de Enfermagem da Universidade de São Paulo. Após o procedimento de contaminação, desafio da área superior da câmara escura portátil e sua posterior secagem, no grupo experimental a superfície foi diretamente friccionada com álcool 70% (p/v) durante 30 segundos. No grupo controle, o mesmo procedimento foi realizado, após a limpeza prévia. Imediatamente, após a evaporação do álcool da superfície, foi realizada a coleta microbiológica por meio da fricção com swab. Em seguida, a ponta do swab foi quebrada e mergulhada em um tubo de ensaio esterilizado com 1 mL de SF e agitado em Votex® por 30 segundos, intermitente e todo o conteúdo do tubo de ensaio foi vertido no centro de uma placa de Petri e, sobre ele, derramados 15 a 20 mL do meio Trypticase Soy Agar à temperatura aproximada de 30ºC. As placas foram deixadas na posição invertida, em ambiente à temperatura aproximada de 22ºC por 72 horas, com leitura diária da recuperação das UFC da Serratia marcescens. O controle positivo foi colhido da mesma forma que o dos Grupos Controle e Experimental, porém sem a aplicação de métodos para descontaminação. As médias das UFC foram comparadas entre os grupos experimental e controle, por meio do teste estatístico t de Student. Os resultados permitiram concluir que o álcool 70% p/v, quando aplicado diretamente sobre a superfície contaminada com matéria orgânica sob fricção, é um desinfetante eficaz, comprovado pela redução de seis logaritmos da população microbiana intencionalmente desafiada nos experimentos, não diferindo da redução observada no grupo controle (p=0,440). Estes achados permitiram atestar a segurança desta prática na limpeza/desinfecção concorrente durante as práticas de radiologia odontológica.
Aiming to avoid cross infection in the context of dental radiology, surfaces that get in direct contact with the hands of the professionals involved in dental procedures are ought to be decontaminated, such as the portable darkroom surfaces. The classical recommendation for the alcohol 70% w/v decontamination (which requires previous cleaning process) is not always applied due to its lack of practicality in addition to the short amount of time between dental procedures; so the decontamination is restricted only to the application of alcohol contradicting then, a priori, the good Practices of Infection Control. This investigation, which was conducted following laboratorial and experimental character, controlled, randomized and blinded, has had as its aim: evaluating comparatively the disinfecting efficacy of rubbing the surfaces of portable darkrooms with 70% w/v alcohol, with and without previous cleaning processes, as an alternative procedure for cleaning/disinfection in dental radiology. Three study groups were established: Control Group: previously contaminated surfaces with the worst case contaminant (test microorganism Serratia marcescens ATCC 14756 added to 10% of human saliva) firstly, traditionally cleaned by rubbing with water and detergent, rinsed afterwards then decontaminated using alcohol 70% w/v; Experimental Group: previously contaminated surfaces with the worst case contaminant similarly to Control Groups sample, however submitted straight away to the decontamination by rubbing with alcohol 70% w/v, with NO previous cleaning processes; Positive control Group: surfaces contaminated with the worst case contaminant. The sampling for both, the experimental and control groups, was 85 units. The experiments were conducted at the Microbiology Laboratory of the Medical-Surgical Nursing Department of the University of Sao Paulos Nursing School. After the worst case contamination procedure of the portable darkrooms upper area and drying, at the experimental group: the surface was directly rubbed with alcohol 70% w/v for thirty seconds. At the control group, the same procedure was performed, however, with previous cleaning following the traditional processes. Immediately after the alcohols evaporation from the surface, a microbiological collection was performed by swab friction. Afterwards, the swabs tip was broken and put in a sterile test-tube with 1mL of sterile saline solution and shaken in Vortex® for thirty seconds, and all its content poured into a Petri dish. Fifteen to 20 mL of Trypticase Soy Agar at approximately 30ºC was poured over the Petri dish. The dishes were left inverted, in an acclimatized environment (approximately at 22ºC) for 72 hours, with daily assessment of the Serratia marcescens CFUs (Colony-forming unit) growths. The positive control was collected following the same procedure as the other groups (control and experimental), with no decontamination methods applied. The CFU levels were compared between the Control and Experimental groups, regarding the statistic test of the t test of Student. The results allowed concluding that the alcohol 70% w/v rubbing, when applied straight to the contaminated surface, is an efficient disinfection method, proved by the 6 logs reduction of the worst case bacterial population; no different from the reduction observed at the control group (p=0,440 test t of Student). These results allow attesting and ratifying the safety of this alternative cleaning/disinfection processes in the context of dental radiology.

Abstract:

Os processos de fermentação em estado sólido (FES) existem há muitos séculos nas civilizações orientais, onde têm sido amplamente utilizados na produção de gêneros alimentícios. No ocidente, a indústria tem trabalhado preferencialmente com os processos de Fermentação Submersa (FS) porque, devido ao meio ser aquoso, existem facilidades para se controlar esse tipo de processo. No entanto, novas demandas (tais como o tratamento de resíduos sólidos) não são inteiramente contempladas pela FS. Por outro lado, os processos de FES podem ser descritos como o crescimento de microorganismos em substratos sólidos na ausência de água livre, podendo suprir essas demandas. Entretanto, também devido a essa característica, a maior dificuldade encontrada é o controle das variáveis internas do biorreator (como, por exemplo, a remoção do calor produzido pela atividade biológica). As pesquisas nesse campo mostram que essa remoção é mais fácil através das trocas pelo ar, por causa das dificuldades de condução térmica em meio sólido. Portanto, torna-se necessário o desenvolvimento de sistemas de controle da aeração que permitam a avaliação dos processos em escala de bancada, diminuindo assim o número de incertezas na modelagem e simulação do processo. Com melhores modelos do processo em escala de bancada, torna-se mais fácil o controle da temperatura no leito de um biorreator de maior escala. Esse trabalho tem por objetivo aplicar uma técnica de controle robusto que seja capaz de garantir os índices de desempenho do sistema em toda a faixa operacional do fluxo e da temperatura ar do biorreator. A planta do sistema foi modelada em nove diferentes condições de temperatura e aeração através de modelos de primeira ordem sem atraso. Esses índices são: tempo de acomodação inferior a 12000 segundo e sobressinal inferior a 10%. O controlador utilizado foi do tipo Proporcional Integrativo (PI). Esse controlador foi sintonizado utilizando a metodologia LMI (do inglês Linear Matrix Inequalities) ou Desigualdades Matriciais Lineares, através das restrições elaboradas no algoritmo iterativo V-K. Os resultados da implementação mostram que as restrições utilizadas no algoritmo são capazes de sintonizar o controlador, mesmo não se conhecendo todas as dinâmicas do sistema de aeração.
The solid-state fermentation (SSF) processes have existed for centuries in Eastern civilizations and have been widely used in the production of foodstuffs. In Western, the industry has worked preferably with the submerged fermentation (SF) processes, because it occurs in aqueous medium and it facilitates the bioreactor control. However, new demands, such as solid waste management, are not fully covered by FS. On the other hand, the processes of FES can be described as the growth of microorganisms on solid substrates in the absence of free water, which can meet this demand. But because of this characteristic, the greater difficulty is the bioreactors internal variables control and the major one the removal of the heat produced by biological activity. Researches in this field show that removal is easier through air exchange, because of the difficulties of thermal conduction in a solid medium. Therefore, it becomes necessary to develop an aeration control system that allows processes evaluation in bench scale, thereby reducing the number of uncertainties in modeling and simulation process. Thus, facilitating the temperature control of a larger-scale bioreactors bed. The aim of this work is to apply a robust control technique that guarantees the systems performance indexes throughout the air flow and temperature operational range. The plant was modeled on a first-order system without delay, at nine different conditions of temperature and aeration. These indixes are: settling time less than 12000 seconds and overshoot less than 10%. The controller used was a Proportional Integrative (PI) type. This controller was tuned using the LMI methodology (Linear Matrix Inequalities) through the V-K iterative algorithm restrictions. The implementation results show that the restrictions used in the algorithm are able to tune the controller, even not knowing all the dynamics of the aeration system.

Esse trabalho apresenta estudos, modelagem e análises de um sistema de bombeio centrífugo submerso (BCS), considerando as características dos principais componentes presentes neste sistema. As contribuições do trabalho estão na partida do BCS, como no desenvolvimento de soluções para mitigar alguns dos problemas observados, como por exemplo, os relacionados à qualidade de energia elétrica nos terminais do BCS. A modelagem de cada equipamento elétrico que compõe o BCS é apresentada no trabalho, destacando-se alguns dos aspectos operacionais relevantes que são considerados na operação. Foi feito um projeto para dimensionamento dos filtros passivos utilizados na atenuação das componentes harmônicas das tensões e correntes produzidas pelo sistema, além de auxiliar na regulação da tensão no ponto em que o BCS está conectado. Nas simulações realizadas, considerou-se um sistema de média tensão com um motor de indução trifásico em gaiola de esquilo de 3835HP que acoplado a uma bomba centrífuga possui um alto coeficiente de inércia. Com a inserção de modelos de atritos rotacionais para o torque do conjunto motor-bomba, pôde-se representar os efeitos que acontecem nos instantes iniciais da partida do sistema e avaliar o desempenho da estratégia de controle utilizada para o acionamento. Assim como ocorre nos sistemas reais que são alimentados por cabos submarinos de longo comprimento, utilizou-se um sistema de controle do sistema em malha aberta com uma metodologia para estimar e compensar a queda de tensão que ocorre entre os terminais do conversor e o terminal de entrada do motor elétrico. O trabalho apresenta ainda uma breve comparação entre o conversor fonte de tensão (VSC) de 2 níveis e o conversor de 3 níveis com neutro grampeado (NPC). Por fim, é analisada a situação onde a alimentação do BCS é desequilibrada devido à diferença de valores entre os parâmetros do cabo submarino.
This work shows studies, modelling and analyses of an electrical submersible pump system (ESP), considering the characteristics of key elements in this system. The contributions are in its start-up, as also in the development of solutions for mitigation of some observed problems, e.g., those related to power quality at the equipment terminals. The model for each electrical equipment inside the ESP is presented in this work and highlighted some of the pertinent operational aspects that is commonly considered on practical operation. A project is settled for sizing the passive filters to attenuate the harmonic components of the voltages and currents supplied by the grid, in addition to helping voltage regulation at ESP connection point. In the study cases, it was considered a medium voltage power system with a 3835HP three phase squirrel cage induction motor which is connected with a centrifugal pump that results in a high inertia coefficient. Rotational friction model is considered in the studies to characterize the effects that occur at the initial seconds of the start-up of the system and also to evaluate the performance of the implemented control strategy. In the same way that occurs in real systems that are supplied by downhole electric cables, it was considered an open-loop V/f control with a methodology to estimate and compensate the voltage drop that exists between the terminals of the converter and the motor input. This work also establishes a short comparison between a 2-level voltage source converter (VSC) and a 3-level neutral-point clamped (NPC) VSC. Finally, the system is analyzed through the occurrence of an unbalance of downhole electric cable parameters.

Este estudo teve por objetivo avaliar a sensibilidade pós-operatória e o desempenho clínico de restaurações de resina composta em lesões cervicais não-cariosas (LCNC), com ou sem o uso de agente dessensibilizante à base de oxalato de potássio, por 18 meses. Foram restauradas 144 lesões em 42 pacientes selecionados de acordo com os critérios de inclusão e exclusão estabelecidos, sendo divididos aleatoriamente em quatro grupos: no grupo 1 (G1) as lesões foram restauradas utilizando-se o agente dessensibilizante à base de oxalato de potássio (BisBlock, Bisco, EUA) após o condicionamento ácido e previamente à aplicação do sistema adesivo Adper Single Bond 2 (3M ESPE, EUA). O grupo 2 (G2) foi restaurado com o mesmo sistema adesivo do G1, porém sem a aplicação do agente dessensibilizante. O grupo 3 (G3) foi restaurado utilizando-se o agente dessensibilizante (BisBlock, Bisco, EUA) após o condicionamento ácido e previamente à aplicação do sistema adesivo One-Step (Bisco, EUA). O grupo 4 (G4) foi restaurado com o mesmo sistema adesivo do G3, porém sem a aplicação do agente dessensibilizante. As resinas compostas utilizadas foram: Filtek Supreme (3M ESPE, EUA) no G1 e no G2; e Aelite (Bisco, EUA) no G3 e no G4. As 140 restaurações foram avaliadas por dois examinadores em cinco períodos distintos: inicial, 2, 6, 12 e 18 meses, seguindo os critérios USPHS modificados. Os dados foram submetidos ao teste estatístico de McNemar para verificar possíveis alterações do índice Alfa dentro dos grupos ao longo do tempo. Para analisar a associação entre os grupos em cada momento, utilizou-se o teste Qui-quadrado. Para todos os critérios estudados adotou-se o nível de 5% de significância. Os resultados revelam que não há diferença estatística entre os grupos restaurados com o agente dessensibilizante em comparação aos grupos controle nos critérios sensibilidade relatada, sensibilidade estimulada e retenção das restaurações ao longo do tempo.

Abstract:

Introdução: Na prática clínica odontológica, justificada pela praticidade, tempo curto disponível entre os atendimentos, associados à insuficiente previsão e provisão das Canetas de Alta Rotação (CAR), a descontaminação destas por meio de aplicação direta do álcool 70% p/v, sem limpeza prévia, é uma realidade. Este procedimento contraria, a priori, os protocolos de processamento que recomendam, no mínimo, limpeza seguida de desinfecção de alto nível para prevenção de infecção cruzada. Objetivo: avaliar a desinfecção das CAR com álcool 70% p/v, sem limpeza prévia com vistas ao risco de causar infecção cruzada. Método: caracterizou-se como uma pesquisa pragmática em um Estabelecimento Odontológico, onde rotineiramente as práticas de interesse para o estudo estavam presentes. O grupo experimental foi composto por 100 amostras de CAR utilizadas em tratamentos diversos, após a fricção do desinfetante por 90 segundos em sua superfície externa. Para avaliação dos resultados, uma gaze umedecida com soro fisiológico foi utilizada como carreador para o arraste dos possíveis micro-organismos nas superfícies desinfetadas. Metade do número das amostras (50) foi analisada pelo método de filtração por membrana (Método I - quantitativo), sendo cada gaze imersa em 300 mL de solução fisiológica. Sequencialmente, as amostras foram expostas a sonicação e agitação. Em seguida, o lavado foi filtrado em três partes iguais para diferentes análises (micro-organismos aeróbios, anaeróbios e específicos da microbiota oral humana), por meio da membrana com porosidade de 0,45 m. As outras 50 amostras foram analisadas pelo método de imersão direta da gaze em meio de cultura Fluid Thioglycollate Medium (Método II qualitativo). O tubo contendo a gaze foi agitado e incubado a 37ºC por 21 dias. Resultados: as amostras analisadas pelo Método I apresentaram crescimento positivo em 27/50 (54%) das amostras na faixa de 100 a 102 UFC/amostra. Deste total, foram identificados sete micro-organismos distintos, representados por 37,1% do Staphylococcus coagulase negativa, 28,5% dos Bacillus spp, 17,1% dos Bacilo Gram positivos não esporulados, 5,7% dos Micrococcus spp, 5,7% dos Penicillium spp, 2,8% Acinetobacter baumannii e 2,8% da Candida spp. No grupo analisado pelo Método II, o total de tubos com crescimento positivo foi de 12/50 (24%) amostras. Deste total, foram identificados três micro-organismos distintos, sendo 38,4% de Bacilos Gram positivos inespecíficos, seguidos dos Staphylococcus spp e Peptococcus spp com a mesma porcentagem de positividade de 30,7% cada. O grupo controle negativo, composto por amostras submetidas à limpeza e esterilização consecutiva, apresentaram resultados satisfatórios de ausência microbiana na totalidade das amostras. O crescimento médio encontrado no grupo controle positivo foi de 17,5 UFC/placa, com exceção de uma amostra que apresentou crescimento incontável. Conclusão: os resultados da presente investigação reprovam a prática da descontaminação das CAR com álcool 70% p/v, sem limpeza prévia, substanciada pela sobrevivência de micro-organismos que não corresponderam à ação fungicida e bactericida esperada do álcool 70% p/v na condição de desinfetante de nível intermediário. Outro aspecto que reforça a reprovação da prática analisada é a consideração de que os micro-organismos recuperados, mesmo sendo de baixo potencial patogênico, podem comportar-se como anfibiontes, isto é, são capazes de agredir o hospedeiro quando as condições ambientais e imunológicas são favoráveis aos micro-organismos, causando infecção.
Introduction: In dental clinical practice, decontamination of high-speed dental equipment (HSDE) by direct use of 70% ethanol without previous cleaning, justified by practicality, the short-time available between appointments, together with inadequate predicting and provision of HSDE, is a reality. This procedure, a priori, contradicts the processing protocols recommended to prevent cross-infection. Objective: to evaluate the disinfection of HSDE with 70% ethanol without previous cleaning, with views of cross-infection risk. Method: the present study was characterized as a pragmatic research in a Dental Office, which practices of interest to the study were routinely performed. The experimental group consisted of 100 samples of HSDE used in different treatments after rubbing the disinfectant for 90 seconds on its outer surface. To evaluate the results, gauze moistened with saline solution was used as a carrier for obtaining microorganisms from the disinfected surfaces. Half of the samples (50) were analyzed by membrane filtration (Method I - quantitative), with the gauze being immersed in 300 mL of saline solution. Sequentially, the sample was exposed to sonication and agitation. After that, the lavage was filtered in three equal parts for different analyses, through a membrane with 0.45 m porosity and seeded on blood agar culture medium, for recovery of aerobic and anaerobic microorganisms, as well as those specifically found in the human oral microbiota. The other 50 samples were analyzed by direct immersion of the gauze in culture medium (Method II - Qualitative): after rubbing the wet gauze on the outer surface of the HSDE, it was placed directly in Fluid Thioglycollate culture medium. The tube containing the gauze was shaken in a vortex mixer and then incubated at 37 ° C for 21 days. Results: samples analyzed by Method I, showed positive growth in 27/50 (54%) of the samples within the range of 100 to 102 CFU/sample. Of this total, 7 different microorganisms were identified, represented by 37.1% of coagulase-negative Staphylococcus, 28.5% of Bacillus spp, 17.1% of non-sporulating Gram-positive bacillus, 5.7% of Micrococcus spp, 5.7 % of Penicillium spp, 2.8% of Acinetobacter baumannii and 2.8% of Candida spp. In the group analyzed by Method II, the total number of tubes with positive growth was 12/50 (24%) samples. Of this total, we identified 2 different microorganisms, being 38.4% of Gram-positive bacillus nonspecific, followed by Staphylococcus spp and Peptococcus spp with the same percentage of positivity of 30.7% each. The negative control group, composed of samples subjected to cleaning and sterilization consecutive showed satisfactory results. The average growth found in the positive control group was 17.5 CFU/sample, except for one sample that showed growth uncountable. Conclusion: the results of the present study do not support the practice of decontamination of HSDE with 70% ethanol without previous cleaning, based on the evidence of microorganism survival that did not meet the expected bactericidal and fungicidal action of alcohol as an intermediate level disinfectant. Another aspect that reinforces the disapproval this practice, it is the consideration that the micro-organisms recovered, even being low pathogenic potential, may behave as anfibionte, which are capable of harming the host when the environmental and immune conditions are favorable to micro-organisms, causing infection.

This dissertation discusses the practical results of the Program called Servico de Convivencia e Fortalecimento de Vinclulos (SCFV) currently under the responsibility of the Ministry of Social Development and Fight against Hunger (MDS). This Program takes place in all six units of the Social Assistance Reference Center (CRAS ) that actlined form in specific territories from urban to rural ?reas in the municipality of Itaguai (RJ), Brazil. This municipality has recently experienced a series of socio-economic and environmental changes that directly impacted it territory. The purpose of this research is to evaluate the practical applicability of the social dimension of this particular public policy, created from dialogical process and a hierarchical design of their socialization premises. This will be possible by comparative analysis between the normative theories and methodologies proposed by the federal government, practices presented in SCFV at the municipal level and analysis based on the survey results conducted with local stakeholders (users - civil society, professional service and local public administration). The methodology focused in the qualitative research saturation model feature. It was held a total of one hundred and four interviews, besides visits and field research in the six existing units in Itaguai (RJ). For a better analysis of theory and practical results we have also used the terms social management, social control and deliberative citizenship as basic tools for delineation of proposing the research, as each of these terms bring a deep discussion about rationality and the communicative and cooperative processes between the state and civil society. In other words, this research seeks to understand how ave being arrived out the guiding proposals and methodological aspects of the SCFV public policies by MDS national scale and compare it with the practical applicability in the local level

Abstract:

Vertical/Short Take-Off arid Landing (V/STOL) fighter aircraft are characterised by increased control complexity caused by the extra degree ol freedom. This can result in a high pilot workload which may be alleviated with the careful application of active flight control. However, the advent of control configured vehicles demands that the controller design must be part of a fully integrated and iterative aircraft design; hence it must allow the two-way flow of design information. In this thesis a suitable controller design method is developed to solve this two-fold problem. The method is based upon a singular perturbation analysis which is used to expose the underlying dynamics of a closed-loop state-space system. developments are described which allow high-order, dynamically complex parasitics, such as actuators, to be included in the design. Furthermore, the method gives the designer insight into the problem allowing tuning and engineering trade-offs to be performed intelligently with a two-way flow of design information. The end result is a robust high-gain multivariable controller. In order fully to develop arid analyse the method it has been applied to a representative non-linear time-varying aircraft simulation model. This LS supplied by the Royal Aerospace Establishment, Bedford. The necessary slate-space matrices are otitairted by lirLearisirig the model at several different flight cases. This occurs over a wide flight envelope, from hover to 300 Kts, and consequently the multivariable control laws are implemented using gain scheduling. Finally, task tailored control and handling qualities requirements are derived for a V/STOL aircraft in the form of a design brief. This design brief is then fulfilled by designing a controller which alleviates pilot workload during transitions from jet-borne to fully wing-borne flight (and vice versa).

Abstract:

Regime recognition is an important tool used in creation of usage spectra and fatigue loads analysis. While a variety of regime recognition algorithms have been developed and deployed to date, verification and validation (V&V) of such algorithms is still a labor intensive process that is largely subjective. The current V&V process for regime recognition codes involves a comparison of scripted flight test data to regime recognition algorithm outputs. This is problematic because scripted flight test data is expensive to obtain, may not accurately match the maneuver script, and is often used to train the regime recognition algorithms and thus is not appropriate for V&V purposes. In this paper, a simulation-based virtual pilot algorithm is proposed as an alternative to physical testing for generating V&V flight test data. A “virtual pilot” is an algorithm that replicates a human’s piloting and guidance role in simulation by translating high level maneuver instructions into parameterized control laws. Each maneuver regime is associated with a feedback control law, and a control architecture is defined which provides for seamless transitions between maneuvers and allows for execution of an arbitrary maneuver script in simulation. The proposed algorithm does not require training data, iterative learning, or optimization, but rather utilizes a tuned model and feedback control laws defined for each maneuver. As a result, synthetic HUMS data may be generated and used in a highly automated regime recognition V&V process. In this thesis, the virtual pilot algorithm is formulated and the component feedback control laws and maneuver transition schemes are defined. Example synthetic HUMS data is generated using a simulation model of the SH-60B, and virtual pilot fidelity is demonstrated through both conformance to the ADS-33 standards for selected Mission Task Elements and comparison to actual HUMS data.

A matriz energética mundial é bastante dependente das fontes não renováveis de energia, assim, a adoção de novas tecnologias e estratégias que visem à eficiência energética são ações fundamentais, face às mudanças climáticas, escassez dos recursos naturais e demanda crescente de energia. Nesse sentido, o progresso autônomo da tecnologia dos LEDs, do inglês “Light-Emitting Diode”, e o progresso induzido, praticado pelo governo brasileiro, em eficiência energética são alavancas propulsoras para o crescimento das medidas de conservação de energia em todos os setores da economia. Nesse contexto, o presente trabalho vem propor uma metodologia que busca reduzir o consumo de energia elétrica na Administração Pública. O método proposto é aplicado em um estudo de caso na Superintendência do Desenvolvimento da Amazônia (SUDAM), uma Autarquia Federal, utilizando-se, em um primeiro momento, de um pré-diagnóstico energético capaz de embasar a implementação de Ações de Eficiência Energética (AEE) por meio de medidas técnico-administrativas e, em um segundo momento, amparado por um diagnóstico energético aprofundado no sistema de iluminação artificial, sugere e emprega o LED na iluminação artificial de alguns ambientes da SUDAM. Para subsidiar a metodologia proposta é utilizado o software RETScreen® e a metodologia do Guia de M&V (Medição e Verificação) da Agência Nacional de Energia Elétrica (ANEEL) tendo como premissas, respectivamente, analisar a oportunidade percebida no diagnóstico energético e quantificar os resultados obtidos admitindo a substituição de todas as lâmpadas antigas por lâmpadas LED. O trabalho apresenta os resultados, satisfatórios, provenientes das Ações de Eficiência Energética e conclui também que a utilização do LED na iluminação artificial da SUDAM possui viabilidade de aplicação com recursos próprios da Instituição, configura-se como uma proposta de projeto válida para Chamadas Públicas, que devem ser ofertadas pela concessionária de energia local, no âmbito do Programa de Eficiência Energética (PEE) regulado pela ANEEL, possibilidade de obter a Etiqueta Nacional de Conservação de Energia (ENCE) parcial para o sistema de iluminação e ainda servir como parâmetro e motivação para os demais Órgãos do Setor Público.
The world energy matrix is a lot dependent of non-renewable energy source, thus, the adoption of new technologies and strategies that aim the Energy Efficiency are actions fundamental, against climate changes, scarcity of natural resources and increase energy demand. This form, an autonomous progress of Lights-Emitting Diodes (LED) technology and an induction progress, practiced for Brasilian Government, in Energy Efficiency are levers to growth action energy conservation in all sectors of the economy. With that intent, this work comes to propose an methodology that search reduce the energy consumption in Public Administration. The method proposed is applied in case study in Amazon Development Superintendence (SUDAM), an Autarchy the Federal, using, in a first moment, of a pre-diagnosis capable of to base the implementation of energy efficiency action by means of steps technical-administrative and, in a second moment, supported by an deep energy diagnosis in artificial lighting system, it suggests and employs the LED in lighting some SUDAM environments. To subsidize the proposed methodology is used the software RETScreen® and the methodology of Measure and Verification Guide of the National Electrical Energy Agency (ANEEL), by having like premise, respectively, an analyze of an opportunity perceived in energy diagnostic and results quantify obtained admitting the renewal of all old lamps for LED lamps. The work presents results, satisfactory, from of energy efficiency actions and it concludes also that use of LED in artificial lighting of SUDAM it has viability application with own resource Institution’s, sets up like a propose valid of project to Calls Public, that must be offered by electrical utility, in ambit of the Efficient Energy Program regulated by the ANEEL, possibility of get National Energy Conservation Label, partial, to lighting system and still serve like parameter and motivation to the other Agencies of Public Sector.

A explosão da informação no campo da comunicação coincide, na década de 1970, com a consolidação da sociedade da informação e do conhecimento, que tem a característica principal de multiplicação de registros, formatos, formas e suportes. O release, documento das assessorias de imprensa, ganha uma nova configuração, deixando de apresentar conteúdo simples, com indicativo de uma ação que irá ocorrer, para tornar-se descrição fiel e aprofundada dessas informações oficiais, com estrutura semelhante a uma reportagem. Por questões como a pressão do tempo e a falta de equipe nas redações e mesmo decisões éticas pessoais, esses releases têm sido copiados na íntegra ou parcialmente modificados por três sites de informação jornalística de Campo Grande, Mato Grosso do Sul. Essa atitude é polêmica entre os produtores de informação jornalística on-line, a quem caberia questionar as informações contidas no release original e contrapô-las com as de outras fontes, com diferentes pontos de vista da mesma ação. _________________________________________________________________________________________ ABSTRACT

Abstract:

The diploma thesis deals with the analysis of the current status of controlling in the company Skynet, a.s. and suggests improvements by using controlling as a subsystem of the management system. The financial analysis, which is the crucial tool for decision making in the corporate management, is used to evaluate the corporate history and current state. In the first part of the financial analysis, the corporate economical status is evaluated using the analysis of the relative data, while in the second part, it is evaluated using the aggregate data. In the following chapter, the internal economy of the company is discussed, including calculations, optimization of deviations and the consequences of the inclusion of controlling into the management process. It is concluded that if controlling is used in the management process, the competitive edge grows thanks to the improved adaptability to the business environment and more flexible strategic management.

Full text

Abstract:

Les matériaux semi-conducteurs III-V A non stoechiometrie controlée (ga 1 xas 1 + x) sont obtenus par épitaxie par jets moleculaires sur des substrats dont la température de croissance est fixée entre 200-400\c. Durant la croissance, jusqu'à 0. 5% d'as est incorporé en excès. Les conséquences de cet écart à la stochiométrie sont un temps de vie ultra court des électrons ( 1 ps) et une très grande résistivité après recuit. Nous avons d'abord étudié les defauts présents dans le matériau par les moyens classiques de caractérisation des solides (diffraction par rayon x, absorption infra rouge, microscopie électronique). La corrélation entre les informations apportées par les différentes méthodes de caractérisation, nous a permis d'identifier le défaut majoritaire dans ce matériau et de proposer un modele decrivant son incorporation et son recuit. D'autre part, nous avons etudie la dynamique de recombinaison des porteurs dans ce materiau par des experiences de photoconduction et de photoreflectance resolues en temps. Un modele permettant d'expliquer l'ensemble des propriétés de la recombinaison des porteurs a été developpé. L'intérèt de l'étude est de disposer de matériaux dont on peut maitriser le temps de vie des porteurs. Ceci permettra la fabrication et l'optimisation de commutateurs commandes optiquement travaillant à des fréquences très élevées (> 10 ghz). Enfin, nous avons étudié le confinement des défauts ponctuels de ce matériau et nous avons démontré la possibilité d'incorporer dans le même échantillon, des couches minces avec un temps de vie ajustable, à proximité immédiate de couches dont le temps de vie n'est pas modifié. Ceci a ouvert la voie à de nouveaux concepts que l'on peut regrouper sous le terme général d'ingénierie quantique du temps de vie. Des échantillons demontrant la possibilité d'un controle sélectif du temps de vie des électrons d'un puits quantique en fonction de leur niveau d'énergie dans le puits, ont été réalisés.

Abstract:

The work deals with relatively new components allowing electric energy accumulation – ultracapacitors. It focuses on their application in traffic systems – in independent electric vehicles. Design and verification of a system with ultracapacitor and DC/DC adaptive converter was done. Control of the adaptive converter modifies very positively the time wafeform of the traction accumulator current during the drive cycle. The designed connection of ultracapacitor and DC/DC converter implemented in the drive structure of experimental electric vehicle with induction machine contributes to increment the action radius of the vehicle by 16% (determined by experimental verification). This result was achived particularly by limitation of traction accumulator current peaks, And by more effective storage of energy gained by recuperative braking of the vehicle as well. The core of the system is a control of the adaptive converter in order to provide an active filtration of the accumulator’s current to its long-period mean value, i.e. elimination of current (power) peaks. These are caused by acceleration from non-zero initial vehicle speed or by recuperative braking. This is done by a subsidiary current loop. The converter has a superior voltage regulation loop, which sets in long-time period the voltage of ultracapacitors to the proper value – indirectly dependent on the speed of the vehicle. This ensures the appropriate energy management of the ultracapacitor. In the following, properties of test set of ultracapacitors were verified. Finally, methods of suppression of capacity variability influence in series connection of these components were compiled and critically reviewed.

Abstract:

The proposed work is dealing with control design of pump-tank system as part of broader water-supply network with using of mechatronic approach. The main goal of this work is design of control for regulation of flow, pressure and water level in tank in water-supply network of Vsetin city. This water-supply network consists of various components, such as pumps, pipes, valves, tanks etc. For the purpose of the control design is necessary to create a model of pipe network. The solution of hydraulic analysis is obtained by using the gradient method, which was implemented into the software solution named ADAM. The results of hydraulic analysis are compared with measured values of flow and pressure and difference of these values has to be minimalized by proposed calibration and verification process. The calibration and verification process was implemented in software ADAM. The essence of design control is formulating control problem as optimization problem. Therefore the output of higher control layer is set of procedural rules, which determines for example speed of pumps in time etc. Results were verified by using for this purpose developed computational server (ADAM Server).
