s functions are in general Sommerfeld-type integrals which are computationally expensive. To improve the efficiency of the technique, Green&rsquo
s functions are approximated by their closed-forms. Microstrip lines are excited by arbitrarily located current sources and are terminated by complex loads at both ends. Current distributions over microstrip lines are represented by rooftop basis functions. At first step, the current distribution over a single microstrip line is calculated. Next, the calculation of the current distributions over coupled microstrip lines is performed. The technique is then, applied to directional couplers. Using the current distributions obtained by the analysis, the scattering parameters of the structures are evaluated by using Prony&rsquo

Pełny tekst źródłaLa combinación de acetato de zinc y etanolamina conforma el precursor de sol-gel más utilizado para la producción de ZnO con fines de electrónica impresa. Aunque las propiedades de tinta basadas en precursores se han reportado ampliamente, las razones por las que el material de ZnO se forma de cierta manera a partir de condiciones iniciales específicas todavía no se conocen bien. En el presente trabajo, la estructura de la mezcla se caracteriza experimentalmente y se compara con los modelos moleculares optimizados mediante simulaciones. Además, se ha demostrado tanto los procesos que llevan a su degradación a temperatura ambiente como la descripción del proceso de descomposición indica efectos de sustituyentes importantes en este precursor basado en nitrógeno, que se analizan mejor comparando varios amino-alcoholes con diferentes sustituciones de radicales. La falta de control sobre los efectos de estos amino-alcoholes en el material final hace deseable aumentar el número de interacciones Zn-O (más débiles) a expensas de eliminar los enlaces Zn-N (más intensos). En consecuencia, se han diseñado nuevos precursores sobre la base de la Química verde recurriendo para ello a ácidos carboxílicos naturales. Se describen aquí sus estructuras cristalinas y procesos de descomposición térmica, que consisten en pasos más limpios y en la producción de un ZnO más puro a temperaturas más bajas que cuando se usan amino-alcoholes para estabilizar el metal Zn (II). Al agregar solventes comunes (agua y etanol), las tintas obtenidas muestran claras mejoras para las tecnologías de impresión basadas en precursores de ZnO. Como último estudio, se procedió a la incorporación de un segundo metal en este tipo de precursores, el hierro, con el fin de estudiar la conveniencia en la disposición de dos metales que, en función de la atmosfera en la que se descomponga el precursor, generen una proporción controlada de Franklinita (conocida por sus propiedades magnéticas) con respecto a la proporción de ZnO. Un estudio futuro más detallado sobre esta Franklinita podría, incluso, detallar las condiciones en las que encontrar la proporción de Fe(II)/Fe(III), y por tanto su capacidad magnética, deseada para cada fin.

Pełny tekst źródłaHe electromagnetic interferences (EMI) coupling inside metallic cavities that constitutes the shielding of electronic cards is an important problem in the electromagnetic compatibility (EMC) domain. The electromagnetic (EM) coupling with transmission lines (TL) or other objects located inside an enclosure has been investigated by different authors. Previous analyses have been made using numerical and analytical methods. The goal of the research work presented in this manuscript is to make a contribution to a better understanding of the analytical models allowing to predict the EM coupling level induced on an electronic device. After the establishment the physical model for the modal representation of the Green function (GF), the first part is devoted to analyse the EM coupling within enclosure by using the ILCM (Intermediat Level Circuit Model) technique. In the second part of this manuscript, we have exploited the ILCM model for predicting the EM coupling with elementary antennas fixed within enclosure. Finally, in the last part, a simple and efficient analytical model has been developed for the prediction of the electromagnetic (EM) field coupling with a lossless transmission line (TL) located in a rectangular enclosure. The analytical results have been successfully compared over a wide frequency band with Temsi-FD and experimental results

Microstrip antennas are widely used in modern telecommunication systems. This is particularly due to the great variety of geometries and because they are easily built and integrated to other high frequency devices and circuits. This work presents a study of the properties of the microstrip antenna with an aperture impressed in the conducting patch. Besides, the analysis is performed for isotropic and anisotropic dielectric substrates. The Multiport Network Model MNM is used in combination with the Segmentation Method and the Greens function technique in the analysis of the considered microstrip antenna geometries. The numerical analysis is performed by using the boundary value problem solution, by considering separately the impedance matrix of the structure segments. The analysis for the complete structure is implemented by choosing properly the number and location of the neighboor element ports. The numerial analysis is performed for the following antenna geometries: resonant cavity, microstrip rectangular patch antenna, and microstrip rectangular patch antenna with aperture. The analysis is firstly developed for microstrip antennas on isotropic substrates, and then extended to the case of microstrip antennas on anisotropic substrates by using a Mapping Method. The experimental work is described and related to the development of several prototypes of rectangular microstrip patch antennas wtih and without rectangular apertures. A good agreement was observed between the simulated and measured results. Thereafter, a good agreement was also observed between the results of this work and those shown in literature for microstrip antennas on isotropic substrates. Furthermore, results are proposed for rectangular microstrip patch antennas wtih rectangular apertures in the conducting patch

Pełny tekst źródłaThe 3D integration is the most promising technological solution to track the level of integration dictated by Moore's Law (see more than Moore, Moore versus more). It leads to important research for a dozen years. It can superimpose different circuits and components in one box. Its main advantage is to allow a combination of heterogeneous and highly specialized technologies for the establishment of a complete system, while maintaining a high level of performance with very short connections between the different circuits. The objective of this work is to provide consistent modeling via crossing, and / or contacts in the substrate, with various degrees of finesse / precision to allow the high-level designer to manage and especially to optimize the partitioning between the different strata. This modelization involves the development of multiple views at different levels of abstraction: the physical model to "high level" model. This would allow to address various issues faced in the design process: - The physical model using an electromagnetic simulation based on 2D or 3D ( finite element solver ) is used to optimize the via (materials, dimensions etc..) It determines the electrical performance of the via, including high frequency. Electromagnetic simulations also quantify the coupling between adjacent via. - The analytical compact of via their coupling model, based on a description of transmission line or Green cores is used for the simulations at the block level and Spice type simulations. Analytical models are often validated against measurements and / or physical models

Foram analisados os parâmetros físico-químicos: temperatura do líquido e do ar, pH, alcalinidade total (AT), alcalinidade a bicarbonato (AB), ácidos voláteis (AV), demanda química de oxigênio (DQO), demanda bioquímica de oxigênio (DBO520), Turbidez, Sólidos Totais (ST), Sólidos Suspensos Totais (SST), nitrogênio total kjeldahl (N-NTK), nitrogênio amoniacal (Namon), nitrito(N-NO2-), nitrato (N-NO3-) e fósforo total (P). Foi avaliado o comportamento hidrodinâmico e verificada a existência de anomalias hidráulicas, pela técnica de estímulo-resposta tipo pulso com injeção do traçador eosina Y. Ao final dos experimentos, foi realizada a análise estatística para encontrar a condição operacional ótima, bem como os modelos estatísticos para validação dos experimentos. Em todas as condições operacionais foi possível observar que o reator UAHB entrou em equilíbrio dinâmico aparente (EEDA) com produção de alcalinidade para neutralizar os ácidos voláteis produzidos no processo de acidogênese e acetogênese da digestão anaeróbia. O aumento da carga orgânica volumétrica acarretou no aumento das eficiências de remoção em DQO (amostras brutas e filtradas), DBO520 e Turbidez, mas reduziu as remoções de Sólidos Totais e Sólidos Suspensos Totais. A diminuição do TDH reduziu as eficiências de remoção dos parâmetros DQO (amostras brutas e filtradas), DBO520, Sólidos Totais, Sólidos Suspensos Totais e Turbidez. Em relação à hidrodinâmica, em todas as condições operacionais foi observado o efeito de cauda longa, o regime de escoamento no interior do reator UAHB foi classificado como de tanques de mistura completa em série (NCSTR). Foi verificada a presença de zonas mortas no reator, a eficiência hidráulica foi em média 65% para as três condições e não foi possível observar a presença de curtos-circuitos para os três TDH testados.

The anaerobic digestion process is very important in the treatment of sewage, as it is an efficient, simple process and low cost of implementation, operation and maintenance. Although Brazil has provided consolidated anaerobic processes, sanitation is still poor in the country, and the optimization of anaerobic reactors aims to improve the viability, effectiveness and expansion of treatment systems for sewage. The aim of this research project is to evaluate the reactor's performance through dynamic and hydrodynamic behavior of hybrid anaerobic reactor (UAHB) with a range of hydraulic retention time (HRT) of 4 to 12 hours and COD (gross samples) 250 - 1250 mgO2L -1. The reactor, with a volume of 22.1 L was operated with support means corrugated rings of Polyvinyl chloride (PVC) and kept at room temperature, the influent feed, simulating the synthetic wastewater. the physicochemical parameters were analyzed: temperature of the liquid and air, pH, total alkalinity (TA), bicarbonate alkalinity (BA), volatile acids (VA), chemical oxygen demand (COD), biochemical oxygen demand (BOD ), Turbidity, Total Solids (TS), total suspended solids (TSS), nitrogen Total Kjeldahl (NTK-N), ammonia nitrogen (amon-N), nitrite (NO2-N), nitrate (NO3-N) and Total phosphorus (P). It evaluated the hydrodynamic behavior and the determination of hydraulic anomalies, the stimulus-response pulse technique with injection of the tracer eosin Y. At the end of the experiments, statistical analysis was performed to find the optimal operating condition as well as the statistical models for validation experiments. In all operating conditions it was observed that the UAHB Reactor became apparent dynamic equilibrium (ADE) with alkalinity production to neutralize the volatile acids produced in acetogenesis process of anaerobic digestion. The increased of organic loading rate resulted in increased efficiencies in the removal of COD (gross and filtered samples), BOD and Turbidity, but reduced removals of Total Solids and Total Suspended Solids. The decrease in HRT reduced the removal efficiencies of COD parameters (grosss and filtered samples), BOD, Total Solids, Total Suspended Solids and Turbidity. Regarding the hydrodynamic in all operating conditions was observed long tail effect, the flow regime inside the reactor UAHB was rated as complete mixing tanks in series (N-CSTR). The presence of dead zones in the reactor was checked, the hydraulic efficiency was averaged 65% for the three conditions and it was not possible to observe the presence of short circuits for the three HRT tested. For the statistical analysis of the central rotary compound design (CRCD), the optimum operating condition for the reactor was to HRT 12 h and COD (gross samples) 553 mgCOD.L-1.

Pełny tekst źródłaCapacitive Micromachined Ultrasonic Transducers (CMUT) have been studied by several international laboratories since the 1990s. Presenting itself as an alternative to traditional piezoelectric transducers, this MEMS (MicroElectroMechanical Systems) inspired technology has now reached the maturity needed for commercialization. In its historic application, medical imaging, many industrial actors propose CMUT probes, such as Hotachi, Kolo Medicals or Butterfly Network to name a few. However, research on these devices continues through studies on design, modeling, manufacturing or for new applications. Through the collaborative project TUMAHI (Highly Integrated Multi-Application capacitive Ultrasonic Transducers) between the GREMAN laboratory and VERMON S.A, two areas of optimization were carried out. The first objective was to create and experimentally validate a CMUT element design strategy to optimize electroacoustic response over bandwidth or sensitivity. The main constraint was to define degrees of freedom and fixed parameters to manufacture CMUTs for various applications and working frequency on a single wafer. Through a 10 MHz centered device for medical imaging, we have varied the size of membranes to have a Broadband and Sensitive configuration. A pressure measurement campaign was carried out with complete and ready-to-use probes to validate the established design criteria. However, the in-depth analysis emphasized that the design approach for the most effective CMUT probe was to optimize the resonance frequency of the first radiation mode to coincide with the desired working frequency. The second study focused on the passivation layer, a protective layer for CMUT elements traditionally designed in silicone polymer, and aimed to implement its impact in modeling tools with a new CMUT / viscoelastic material coupling model. A three-dimensional Green function was used by defining equivalences between elastic and viscoelastic properties and theoretically validated with complementary 2D and 3D Lamb problems. A confrontation with experimental results was initiated by creating a series of oils with variable viscosities and by exciting electrically decoupled CMUT columns to target a more sensitive radiation mode to the shear properties of the medium. The influence of viscosity was identified through the variation of the central frequency and quality factor on the measured and simulated electrical impedance, providing the basis for a viability study of CMUT technology for a viscoelastic sensitive sensor. The consideration of the passivation layer has enabled the retrieval of equivalent behavior to reality but requires a complete database on the viscoelastic properties of materials in the ultrasonic domain to be present in the design steps of a CMUT transducer

At the end of the Twentieth century, the hole in the ozone layer stimulated people to reduce their use of environmentally harmful materials like halogen. Environmental protection by encouraging industries to reduce their use of waste material and conserve resources more carefully is becoming important. This process is known as the “Green Trend”, and ultimately provides people with “Green environmentally friendly products”, through processes such as green design、green manufacturing、green purchase and verification. In the face of the recent green trend, many countries, areas, and businesses are seeking to develop products that incorporate green concepts. The European Union is focusing adopting electrical and energy products with environmental protection features, including: waste electrical and electronic equipment (WEEE), restriction of hazardous substance (RoHS), Eco-design requirements for energy-using products (EuP). Besides the European Union directives, numerous countries and international factories are also establishing laws governing the production and import/expert of electrical energy products. The above countries and businesses control the production of environmentally friendly electrical energy products. It influenced the design, purchase, manufacture control, monitor process, marketing, and service of products used by businesses. Businesses attach considerable importance to environmental protection and meeting customer requests, including: product testing, manufacturing control, legal contracts and so on. As part of the recent green trend, individual countries, areas, and businesses have begun requesting green products. This study applies quality function deployment technology to establish domestic industries capable of capitalizing on the green trend. To estimate company action plan and competition strategy. Thus , it will help enterprises to face the pressure of customers’ requirements and offer the Assurance of process control and product compliance by third party audit, and to gain the orders and enhance the impression of Green. It also helps enterprises to pass the audit of Green Supplier Chain and to achieve continuous operating. The enterprises will be responsible to social responsibility of environmental protection and improve their company’s impressions.

Local special products are not unfamiliar things for Taiwanese. By adding the place-name before the product, it seems to be the guarantee for quality and let it more popular. And cause the functions of prospering local properties and uniting solidarities, There is a boom in Taiwan for developing local special products. Among them, Sanshin green onion is the special one: not just its short history, but also green onion is a commonly used and cheap ingredient in Chinese culinary culture. And how this mundane thing suddenly become a famous local special product, I think it’s from the effect of specialty, which makes things be unique. This material culture research thesis uses Du Gay’s concept “cultural circuit” for foundation. And through the analysis of media context and interview the industries of Sanshin green onion, I observe the operation of production, consumption, representation, regulation, identity, and the interaction among their articulations, to explore the making process of specialty from the viewpoint of things: by the cultivation of farmers and the regulation from certification, make Sanshin green onions grow longer white stalk, stronger fragrance, and more reliable in food safety. Then, in the representation from media and display, not only emphasize their high quality and high price, but also use traditional, rural and local images to promote them. Under these physical and symbolic characteristics overlapped, the specialty of Sanshin green onion gradually appears, and identified by producers and consumers. But in the responses of consumers, I find out that there is a split between physical and symbolic characteristics: although hearing the fame, they usually don’t know what the physical characteristics are certainly. And in the experiences of interviewees, selling healthy Sanshin green onions let them have some difficulties. These examples about the dislocation of identity express the features and problems of specialty: 1.Symbolized place-name becomes a crucial point of distinction and the endorsement of quality. 2. Sanshin green onion becomes the delicious local taste in gourmet and local tourism, but the physical characteristics such as health are not involved in these contexts. 3. When the consumption becomes the ultimate goal of specialty and cultural circuit, the feeling of identity is simply pure no longer, and brining the purpose of profit into the meaning of specialty inevitably.

Pełny tekst źródłaO presente trabalho tem como objetivos a produção e caracterização de circuitos de ótica integrada (OI) eficientes e de baixo custo, no contexto dos requisitos de fotónica sustentável, nomeadamente na área das comunicações óticas e dos sensores. Para isso, híbridos orgânico-inorgânicos (di-ureiasil e tri-ureiasil), dopados com propóxido de zircónio estabilizado com ácido metracrílico, foram sintetizados pela metodologia sol-gel, à temperatura ambiente, como guias de onda planares processados na forma de monólitos, com forma e tamanho controlados, ou filmes de espessura variável (10−5-10−6 m), em substratos vítreos e de silício oxidado. Estes materiais exibem propriedades óticas estáveis e ajustáveis, estabilidade mecânica e térmica resultantes da sinergia entre os componentes orgânicos e inorgânicos. A sua principal propriedade é o fácil controlo das propriedades óticas devido à inerente flexibilidade dos materiais que são auto-padronizados pela escrita direta por radiação ultravioleta (UV), e o controlo do índice de refração por dopagem química. A influência de diferentes concentrações de aglomerados de zircónio (20-60 mol%) na estrutura local dos di-ureails e tri-ureasils foi analisada através de difração de raio-X, ressonância magnética nuclear dos átomos de 13C e 29Si, espectroscopia de infravermelho por transformada de Fourier, espectroscopia Raman por transformada de Fourier e análise termogravimétrica. As características óticas relevantes para aplicações em OI foram determinadas, revelando coeficientes de atenuação aceitáveis (∼1-5 dB·cm−1) para circuitos de baixas dimensões, e baixas perdas de inserção devido à similaridade entre os índices de refração do dispositivo-fibra (1,49-1,52). Tomando partido da fotossensibilidade do material, foi utilizada a escrita direta por radiação UV para padronizar a arquitetura ótica desejada na superfície de híbridos orgânico-inorgânicos. No que respeita às comunicações óticas, foram produzidos dispositivos passivos e ativos: controlador de polarização termo-ótico para monitorizar o estado de polarização de um sinal ótico, apresentando um coeficiente de retardamento linear de 17±1 °/°C; um acoplador híbrido de 90° para demodular uma transmissão de quadratura de chaveamento de fase com 20 Gb/s em 40 km de fibra, resultando numa penalidade de potência de 2,5 dB comparativamente à configuração sem fibra; um modulador de fase eletro-ótico baseado num interferómetro Mach-Zehnder (MZI) com uma diferença de potencial para uma variação de fase de π de 2,9±0,3 V; amplificador ótico na região espectral do azul para comunicações óticas no visível com uma eficiência máxima de ganho ótico de 1,62±0,02 cm∙μJ–1. Na área dos sensores, o desenvolvimento de biosensores portáteis de baixo custo baseados em OI para dispositivos é de grande interesse. Sendo assim, um biosensor baseado na arquitetura de um MZI foi produzido para monitorizar a concentração de bactérias num meio líquido, apresentando uma sensibilidade de 2×10−4 RIU e um limite de deteção de 2,0 pg·mm−3.
