Повний текст джерелаIn the recent years the automotive industry requests, even more, the possibility to perform laboratory tests on prototype vehicles by using real operating conditions. Driven from the automotive market, the electrification of the vehicles cars has taken a significant role. The scope of this thesis is to presents innovative techniques and methodologies applied both to electric vehicle and the testbench: the combination of the dynamic vehicle model with the entire testbench system allows to reach better performance and improve accuracy on real estimated electric vehicles performance. The experimental characterization of the electric motor and the engine is presented together with the real-life phenomena influencing the overall system. The results have been tested in two different use cases: the complete model of a Mild Hybrid Electric Vehicle and non-linear model of a testbench system. The former use case is a linear model where the dynamic and steady-state are modelled, including the influence of external disturbance and noise. With this approach is possible evaluating different control techniques and introduce real GPS sensor data to verify the precision of the model. Two control strategies have been analysed, implemented and compared. The latter use case is a non-linear testbench model that integrates the first use case extending the application environment and using an innovative approach. This approach applied to the system is the Engine-in-the-loop. The choice to use a complex system requests a strong advanced control strategy. For this reason, the Adaptive Model Predictive Control is implemented. Both use cases are verified and validated using standard driving cycles and evaluated through the emission value in terms of carbon dioxide calculated from fuel consumption. These studies have confirmed the possibility of the system to achieve good performance in cases of real application; in this way the engine can be tested in real-time with a vehicle model, or with the innovative test bench system, and inserted into the real process, achieving the scope of the research.

Повний текст джерелаAbstrakt Bakgrund: Förmågan att producera hög effektutveckling (power) kan avgöra vilken idrottare som vinner eller förlorar en tävling. Effektutveckling kan mätas i övningar som knäböj och bänkpress. Detta kan göras med hjälp av en kraftplatta, eller en kraftplatta parad med en linear position transducer. Dessa metoder anses vara ”gold standard”, men linear position transducers eller linear encoders har också ansetts vara valida metoder. Effektutveckling kan även mätas med hjälp av en accelerometer. Syfte: Syftet med denna studie var att mäta samtidig validitet hos accelerometern Beast Sensor genom att mäta genomsnittlig effektutveckling i explosiva knäböj och bänkpressar vid 40 % och 80 % av en repetition max (1RM). MuscleLab, en linear encoder, användes som referensvärde. Metod: 17 försökspersoner, fem kvinnor och tolv män (medelålder 28 år) rekryterades. Femton av försökspersonerna fullföljde deltagande. Vid det första testtillfället mättes 1RM. Det andra tillfället ägde rum 7-14 dagar senare och mätte genomsnittlig effektutveckling i explosiva knäböj och bänkpressar vid 40 % och 80 % av försökspersonernas uppmätta 1RM. Två set av tre repetitioner mättes vid 40 % och 80 % av 1RM i både knäböj och bänkpress. Repetitionerna mättes samtidigt av MuscleLab och Beast Sensor. För att Beast Sensor skulle anses vara valid behövde en korrelationskoefficient på 0.9 eller högre uppnås. Resultat: Beast Sensor uppvisade höga eller väldigt höga korrelationer med MuscleLab för genomsnittlig effektutveckling i explosiva knäböj vid 40 % av 1RM (rs = 0.91) och explosiva bänkpressar vid 40 % (rs = 0.86) och 80 % av 1RM (rs = 0.74). Dock uppmättes en låg korrelation för de explosiva knäböjen vid 80 % av 1RM (rs = 0.42). Alla korrelationer var statistiskt signifikanta med p-värden på < 0.01. Beast Sensor ansågs vara valid för att mäta effektutveckling vid 40 % av 1RM i knäböj, men varken vid 80 % av 1RM i knäböj, eller vid 40 % eller 80 % av 1RM i bänkpressar. Slutsats: Beast Sensor visade höga eller väldigt höga korrelationer med referensvärdet från MuscleLab för tre av de fyra uppmätta variablerna. Endast korrelationen för genomsnittlig effektutveckling i explosiva knäböj vid 40 % av 1RM uppnådde den korrelationskoefficient på 0.9 eller högre som krävdes för att Beast Sensor skulle anses vara valid. Förutom vid 40 % av 1RM i knäböj, missade Beast Sensor en väsentlig andel repetitioner. Därför finns det ett behov av fler studier som undersöker reliabiliteten hos Beast Sensor.

Повний текст джерела[CA] Aquesta tesi doctoral presenta un estudi de compressors scroll amb injecció de vapor (SCVI) per a bombes de calor que operen en climes freds o per a aplicacions d'escalfament d'aigua a alta temperatura. Per a això, es va comparar experimentalment un SCVI amb un compressor de dues etapes de pistons (TSRC) treballant amb R-407C en condicions extremes. La comparació es va realitzar en termes d'eficiències del compressor, capacitat, COP i rendiments estacionals tant per al mode calefacció com per al mode refrigeració. Els resultats proporcionen una idea general sobre el rang d'aplicació dels compressors estudiats i sobre les diferències en els rendiments dels compressors. No obstant això, es van identificar diverses limitacions en la caracterització dels compressors i en l'anàlisi del cicle. Això va motivar a aprofundir en l'estudi del cicle de compressió de dues etapes i els seus components. El següent pas va ser realitzar una anàlisi teòrica dels cicles de compressió de dues etapes per a aplicacions de calefacció, on es va identificar la pressió intermèdia i la relació d'injecció com els paràmetres del sistema més influents sobre el COP. La pressió intermèdia es va optimitzar per a dues configuracions d'injecció (tanc de separació i economitzador) utilitzant diversos refrigerants. Basant-se en els resultats de l'optimització, es va proposar una correlació que permet obtindre la pressió intermèdia òptima del cicle, considerant la influència del subrefredament a l'eixida del condensador. A més, es va analitzar la influència del disseny dels components del sistema sobre el COP del cicle. Posteriorment, l'estudi es va aprofundir a nivell de components. El factor més crític en el sistema és el rendiment del compressor. Per tant, el següent pas va ser avaluar la influència de diversos sistemes de compressió amb injecció de vapor sobre el COP. Es van prendre en compte tres tecnologies de compressors, un SCVI, un TSRC i un compressor scroll de dues etapes (TSSC). Aquestes tecnologies de compressors van ser caracteritzades i modelades per a estudiar el seu rendiment. Per a això, es va proposar una nova metodologia per a caracteritzar compressors scroll amb injecció de vapor. Aquesta metodologia permet avaluar el rendiment del compressor independentment del mecanisme d'injecció que s'utilitza en el cicle. Es va identificar una correlació lineal entre la relació d'injecció de refrigerant i la relació de compressió intermèdia. Aquesta correlació s'utilitza per a determinar el flux màssic d'injecció en funció de la pressió intermèdia. Posteriorment, es va proposar un model semi-empíric de compressors scroll i una metodologia per a estendre aquest model per a compressors scroll amb injecció de vapor. Els models van ser ajustats i validats utilitzant dades experimentals de quatre compressors scroll treballant amb R-290 i un SCVI treballant amb R-407C. Finalment, es va comparar un SCVI amb dos compressors de dues etapes, un TSSC i un TSRC, treballant en condicions extremes. Es va optimitzar la relació de volums dels compressors de dues etapes. Els resultats mostren que, en les condicions nominals de funcionament (Te=-15 °C, Tc=50 °C), la relació de volums òptima del TSSC és 0.58, i del TSRC és 0.57. El TSSC aconsegueix un COP 6% major que el SCVI i un COP 11.7% major que el TSRC. Sota un ampli rang de condicions d'operació, el SCVI presenta una millor eficiència i COP per a relacions de pressió inferiors a 5. Per a relacions de pressió més altes, el TSSC presenta millor rendiment i aconsegueix una temperatura de descàrrega més baixa. Es conclou que el SCVI és una solució fàcil d'implementar, des del punt de vista del mecanitzat, i que permet estendre el mapa de treball dels compressors d'una etapa. No obstant això, els resultats mostren que la compressió en dues etapes aconsegueix millorar en major mesura el COP del cicle i la capacitat, amb una major reducció de la
[EN] This Ph.D. thesis presents a study of scroll compressors with vapor-injection (SCVI) for heat pumps operating in cold climates or in high-temperature water heating applications. To do so, firstly, an SCVI was experimentally compared with a two-stage reciprocating compressor (TSRC) working with R-407C under extreme conditions. The comparison was made in terms of compressor efficiencies, capacity, COP, and seasonal COP, both for heating and cooling modes. The results give a general idea about the application range of the studied compressors and the differences in the compressors' performance. Nevertheless, several restrictions in the compressors' characterization and the cycle analysis were identified. This motivated us to deepen in the study of the two-stage compression cycle and its components. The next step was performing a theoretical analysis of two-stage compression cycles for heating applications, where the intermediate pressure and the injection ratio were identified as the most influential system parameters on the COP. The intermediate pressure was optimized for two vapor-injection configurations (flash tank and economizer) using several refrigerants. Based on the optimization results, a correlation was proposed that allows obtaining the optimal intermediate pressure of the cycle, considering the influence of the subcooling at the condenser outlet. In addition, a theoretical analysis of the influence of the design of the system components on the COP of the cycle was performed. Once the thermodynamic analysis of the two-stage cycle was carried out, the study was deepened at the component level. The most critical factor in the system is the compressor performance. Hence, the next step was evaluating the influence of several compression systems with vapor-injection on the COP. Three compressor technologies were taken into account, an SCVI, a TSRC and a two-stage scroll compressor (TSSC). These compressor technologies were characterized and modeled in order to study their performance. To do so, a new methodology to characterize SCVI was proposed. This methodology allows evaluating the compressor performance independently of the injection mechanism used in the cycle. A linear correlation was identified between the refrigerant injection ratio and the intermediate compression ratio. This correlation is used to determine the injection mass flow as a function of the intermediate pressure. Then, a semi-empirical model of scroll compressors and a methodology to extend the model for scroll compressors with vapor-injection was proposed. The models were adjusted and validated using experimental data from four scroll compressors working with R-290 and an SCVI compressor working with R-407C. Finally, an SCVI was compared with two two-stage compressors, a TSSC, and a TSRC, working in extreme conditions. The displacement ratio of the two-stage compressors was optimized. Results show that, at the nominal operating conditions (Te=-15 °C, Tc=50 °C), the optimal displacement ratio of the TSSC is 0.58, and of the TSRC is 0.57. The TSSC achieves 6% larger COP than the SCVI and 11.7% larger COP than the TSRC. Under a wide range of operating conditions, the SCVI presents a better efficiency and COP for pressure ratios below 5. For higher-pressure ratios, the TSSC presents better performance and achieves lower discharge temperature. It is concluded that the SCVI is an easy solution to implement from the point of view of machining, which allows extending the working map of the single-stage compressors. However, the results show that the two-stage compression technology gets further improve the COP of the cycle and the capacity, with a greater reduction of the discharge temperature operating under extreme conditions.

Повний текст джерелаThis present work reports the chemical and biological analysis of the stem and leaves from Bauhinia pulchella. In this study, the ethanol extract from stems was obtained by maceration, subjected to chromatographic fractionation, leading to isolation of three flavonoids: (+)-3â,4â-dihydroxyphenyl-chroman-7-ol (BP-2), (-)-fisetinidol (BP-3) and (+)-epicatechin (BP-4); a mixture of triterpenes taraxerone and β-amyrenone (BP-1); a mixture of steroids sitosterol and stigmasterol (BP-5); and a bibenzyl named 2-hydroxy-3â,5â-dimethoxybibenzyl (BP-6). It is notewhorthy to mention that BP-1 and BP-4 substances are unprecedented in the genus, while BP-2 is unpublished. Chemical structures of secondary metabolites obtained were elucidated by 1H and 13C NMR; IR and MS associated with comparison of data described in the literature. Chemical composition of the essential oil from leaves of B. pulchella, obtained by hydrodistillation, was determined and quantified by gas chromatography-mass spectroscopy (GC/MS) and gas chromatography-flame ionization detector (GC/FID), which identified 95,68% of all constituents. α-pinene (23.89%); caryophyllene oxide (22.43%) and β-pinene (12.19%) were the major components. The essential oil was tested against Aedes aegypti larvae and showed LC50 value of 105.93 Â 1.48 μg/mL. The cytotoxic activity of essential oil was evaluated on human tumor cell lines (HL-60; MCF-7; NCI-H292 and HEP-2) was evaluated, showing IC50 values with confidence intervals of 9.941 (8.238 to 12.00), 53.05 (41.39 to 67.99), 48.98 (44.22 to 54.25) and 50.42 (42.47 to 59.87) μg/mL, respectively and the cell line HL-60 the most sensitive among the cells tested. This is the first report of the chemical study of Bauhinia pulchella, as well the investigation of larvicidal activity and cytotoxicity of the essential oil from its leaves.

Повний текст джерелаThe brainstem respiratory centers are in charge of breathing regulation. Their output is transmitted to the inspiratory muscles. Respiratory drive monitoring can be performed using the electrical activity of the diaphragm (Eadi) or the measurement of the occlusion pressure at 100 ms (P0.1). Monitoring these parameters should allow improving the delivered ventilator assist. Few data regarding the normal values of Eadi and P0.1 and their variations in non-physiological situations are available. The question of the reliability of the bedside measurements also remains opened.This thesis project aimed at increasing our knowledge on Eadi and P0.1 measurements. The studies performed allowed 1. better characterizing Eadi and P0.1 normal values in physiological and non-physiological situations. 2. demonstrating that Eadi maximal value well reflects inspiratory drive intensity, 3. demonstrating that Eadi monitoring provides additional information compared to respiratory profile and inspiratory effort monitoring, 4. demonstrating that Eadi and P0.1 are well correlated, 5. demonstrating that Eadi can be used to improve the ventilator settings during pressure support and that this strategy allows improving patient-ventilator synchrony. 6. showing that the P0.1 variations are well reflected by the P0.1 measured by the ventilators, 7. demonstrating that overall the P0.1 measured by the ventilators underestimate the reference P0.1. Additional studies in more patients and studies designed to assess the impact on patient’s outcome of using Eadi and P0.1 monitoring should be perform before recommaending these monitorings as a standard procedure in ventilated patients

Após coleta, os frutos foram secos e pulverizados em moinho de facas, sendo este material utilizado para realização dos ensaios de controle de qualidade físico-químicos. Os resultados indicaram que o material vegetal encontra-se dentro dos padrões de qualidade estabelecidos para materiais vegetais. Foi, também, otimizada a condição de extração dos flavonóides presentes nos frutos de D. mollis, preparando-se extratos por turboextração e utilizando-se etanol em diferentes graduações como líquido extrator. Estes extratos foram submetidos ao doseamento por espectrofotometria e avaliados quanto a sua composição química utilizando-se a técnica de Cromatografia em Camada Delgada Comparativa (CCDC). O extrato preparado com etanol absoluto apresentou o maior teor de flavonóides e foi analisado por Cromatografia Líquida de Alta Eficiência (CLAE), confirmando a presença de rutina e quercetina. A partir deste extrato, foram realizadas avaliações da propriedade antioxidante, que mostrou atividade ligeiramente menor que o padrão cisteína, e da citotoxicidade. A emulsão contendo 0,15% do extrato etanólico absoluto, analisada quanto à contaminação microbiológica e quanto à estabilidade, não apresentou sinais de toxicidade dérmica...

Повний текст джерелаZero Net Energy Buildings (ZNEB) are gaining popularity, and many governments want commercial ZNEB status in a decade from now. This project uses the energy consumption data of California State University, Long Beach (CSULB) to design a ZNEB system for the CSULB-Alumni Center. The campus energy data is taken and averaged by considering the number of buildings. Various Energy Efficiency Measures (EEMs) such as scheduled operation of equipment and advanced lighting were considered in designing the ZNEB Alumni Center. The ZNEB System building design is in two different configurations: 1) A system with solar Photo Voltaic (PV); 2) A system with solar PV and a Battery Energy Storage System. The Hybrid Optimization Model for Electric Renewables (HOMER) software simulates the ZNEB Alumni Center. Two configurations are compared in terms of payback and Net Present Value (NPV). The system with the highest NPV and early payback is considered the optimal system.

Повний текст джерела[CA] Amb l'augment de la demanda de solucions més amigables amb el medi ambient en la indústria de l'automoció, el motor de combustió interna alternatiu (MCIA) s'enfronta actualment a grans desafiaments per minimitzar el seu consum de recursos no renovables i especialment, per reduir les seves emissions contaminants . Tenint en compte que l'aportació dels MCIA és fonamental per a cobrir les necessitats de mobilitat i generació d'energia arreu de tot el món, i el fet que diferents alternatives, com els motors elèctrics i híbrids, estan i continuaran enfrontat múltiples obstacles per a la seva implementació massiva al proper futur, la investigació contínua en MCIA és fonamental per complir amb els propòsits de reducció d'emissions. En aquest aspecte, una aproximació per a l'augment de l'eficiència del motor i la reducció de consum de combustible és mitjançant la implementació d'alternatives dirigides a reduir les pèrdues mecàniques per fricció. Aquestes alternatives tribològiques inclouen aquelles que requereixen modificacions de components del motor, com materials i acabats superficials, i l'ús de formulacions d'oli lubricant de menor viscositat o additius que milloren les condicions de lubricació del motor. Amb la constant evolució i millores en el MCIA i les condicions de treball cada vegada més severes, també sorgeixen noves alternatives tribològiques per enfrontar els nous desafiaments del motor, i per tant es requereix d'investigacions addicionals en aquest tema. Durant el desenvolupament d'aquesta Tesi, un dels objectius va consistir a contribuir a la investigació de l'ús d'olis de baixa viscositat per a l'estalvi de combustible com un efecte conjunt amb les condicions de conducció de vehicle. Per dur a terme aquest objectiu, es van desenvolupar assajos experimentals sota condicions estacionàries en un banc de motor amb formulacions d'oli de diferent viscositat HTHS, algunes d'elles amb additiu modificador de fricció per expandir el rang de reducció de fricció a condicions de lubricació més severes . Els mapes de consum de combustible resultants d'aquests assajos van ser utilitzats en un model de simulació del vehicle per estimar el seu consum de combustible com a funció de l'oli i les condicions de treball de tres cicles de conducció. Amb l'objectiu d'expandir els coneixements en els fonaments de lubricació dels MCIAs i tenir la capacitat d'avaluar altres alternatives per reduir les pèrdues per fricció, es va considerar necessari enfocar la recerca al conjunt pistó-camisa, que és el parell tribològic amb major aportació a les perdudes per fricció. Per aconseguir aquest objectiu, durant aquesta Tesi es va desenvolupar una maqueta específica per al acoblament pistó-camisa, i un model teòric per simular la lubricació del segment de compressió. Per a la primera part, la maqueta es va desenvolupar basada en el mètode de camisa flotant, en el qual la camisa va ser aïllada de la resta del motor i la força de fricció generada en la interfície pistó-camisa va poder ser mesurada mitjançant sensors de força. En aquesta instal·lació es van desenvolupar diferents assajos els quals van permetre dur a terme una anàlisi exhaustiva dels fonaments de lubricació d'aquest parell tribològic com a funció de diferents paràmetres que tenen impacte en les condicions de lubricació. Aquest estudi es va complementar amb el desenvolupament d'un model de lubricació per al segment de compressió basat en el mètode de diferències finites. Finalment, es va dur a terme una comparativa de resultats experimentals i teòrics per al segment de compressió, la qual cosa va permetre validar els assajos experimentals a la maqueta de camisa flotant, així com el model de simulació des del punt de vista de dades d'entrada, condicions de contorn i hipòtesis.
[EN] With the increasing demand for greener solutions in the automotive industry, the ICE is currently facing great challenges to minimize the consumption of nonrenewable resources and specially to reduce its harmful emissions. Given that the contribution of the ICE is fundamental to cover the actual mobility and power generation needs worldwide, and the fact that different power-train alternatives, such as electric and hybrid vehicles, are and will continue facing multiple obstacles for their large-scale implementation in the near future, the continuous research on the ICE is fundamental in order to meet the emissions reduction targets. In this regard, one approach to increase the engine efficiency and reduce the fuel consumption, is through the implementation of alternatives aimed to reduce the friction mechanical losses. These tribological alternatives include those that require modifications to the engine components, such as materials and surface finishes, and the use of lubricant oil formulation of lower viscosity or additives that improve the lubrication performance of the engine. With the ongoing evolution and improvement of the ICE and the increasingly severe working conditions, new tribological solutions also emerge to face the new challenges in the ICE, and therefore further research is required on this subject. During the development of this Thesis, one of the objectives was to contribute to the research on low viscosity engine oils for fuel economy as a joint effect with the driving conditions of the vehicle. To accomplish this, experimental tests were performed under stationary conditions in an engine bench test for oil formulations of different HTHS viscosity, some of them with friction modifier additive to expand the friction reduction effect to more severe lubrication conditions. The resultant fuel consumption maps were then employed in a vehicle model to estimate the fuel consumption of the vehicle as function of the oil formulation and the working conditions of the three driving cycles. With the aim of expanding the knowledge on the lubrication fundamentals of the engine and to have the capability to assess other alternatives to further reduce the friction mechanical losses, it was deemed necessary to focus the research on the piston-cylinder liner assembly, the tribo-pair of major friction share. In order to achieve this objective, a test rig was developed in this Thesis specific for the piston-liner assembly, and a theoretical model to estimate the lubrication of the piston compression ring. For the first part, the test rig was designed based on the floating liner method, where the cylinder liner was isolated from the rest of the engine and the friction force generated in the piston-liner conjunction could be measured by means of force sensors. Different tests were developed in this test rig which allowed a comprehensive analysis of the piston lubrication fundamentals as function of different parameters having an impact on the lubrication performance of this assembly. This study was complemented with the development of a piston compression ring lubrication model based on the finite differences method. A comparison of experimental and theoretical results was performed for the piston compression ring that helped to validate both the experimental tests in the floating liner and the simulation model from the point of view of input data, boundary conditions and assumptions.

Estimates of the relative utility of each of the attributes make the approach relevant for destination planning. Segmentation by socio-demographic characteristics and past vacation behaviour makes the research relevant for destination marketing. Choice probabilities can be estimated for any of the scenarios.
The discrete choice experiment can contribute to narrowing the paradigmatic split between destination-oriented and market-oriented tourism research. It is also attractive to applied tourism research because simulation constitutes a convenient tool for managers and decision-makers.

In recent years, the aging population in Taiwan gets serious; more and more elderly have the vestiges on the physiological functions and characteristic of psychology. “Wearing shoes”, seemingly a simply act, causes elders a problem in physical coordination, such as the body movement of sitting down, bending, standing etc. Therefore, the main propose of this research is to improve the designing of chair for shoes and ottoman, further make the elderly feel safer, easier and more comfortable when wearing shoes. At the beginning of research, we’ve used structure interviews and participant observation, understanding the behaviors and habits of wearing shoes in the daily life of the elderly.The studies showed up some observed points. First, a lower chair took the elderly more time to complete the action to sit down, and got more difficult on standing up; secondly, when choosing a shorter chair, it will be easier to wear the shoes because of the extents of bending. However, if the chair is too low, it will affect the large angle on the bending knees, it also brings about the great physical load on the elderly who has the problems on joint degenerations. In order to make the elderly be able to wear shoes more easily, reducing the burden in the process as well, we found the following conclusions: 1.It is recommended to use the chair for shoes at the height 36.78cm ~ 37cm, it’s also could be a useful reference for the designers when they are designing the chairs for shoes wearing in the future. 2.When the height of seat is as high as popliteal, we recommend the optimum height for footstool is at popliteal high -20.87cm ~ -21.11cm, it’s also could be a useful reference for the designers when they are designing the chairs for shoes wearing in the future.

In a good resting place, the bench is the key. This study will review the literature to understand whether the basic attributes of the user and the type of bench affect the user's choice in the bench, which in turn affects the user's different affordances behaviors. The user's active affordance behavior and social affordance behavior in the bench, the research field was selected as the first floor of the National Formosa University of Science and Technology and Management School, and the research bench was linear bench, centripetal bench and convex The font bench is observed, and the user's behavior is observed by a video camera, and finally the film is analyzed by coding. A total of 323 observations were collected in the study. The results of the study showed that in terms of bench selection, the user did not have a preference for the three types of benches when choosing a bench. Instead, in a three-person group, the user was facing the center. Bench preference, gender has no obvious preference for three kinds of benches, male and female mixed groups have preference for embossed bench; user bench affordance, linear bench provides limited affordance behavior, user in a straight line The affordance on the bench is mostly rested alone. The centripetal bench facilitates the social interaction of the group. The embossed bench allows the user to perform the affordances behavior other than sitting. There is a certain affordances behavior for the user, but it is still not as good as the centripetal bench and the convex type bench.

Abstract The reliable material property of device layer on SOI wafer is suitable for fabricating micro devices, but the current proposed processes of SOI wafer are too simple to manufacture devices with various functionalities. On the contrary, the surface micromachining is good at achieving complicated design; but the residual stress of thin film destroys devices. Combining the individual advantages of SOI wafer and surface micromachining, an integration process is established by trench-refilled technology in the thesis. The microoptical bench with the proposed integration process is comprised of micro optical device, some hinges and latches on a comb-drive micro bench. By decoupling the functionalities of actuator and passive optical device, the performance of the two components will be significantly improved. The proposed microoptical bench provides active light modulation with actuator, which is capable of increasing the applications of microoptical bench. Besides, the fabricated high-aspect-ratio actuators with single crystal silicon have excellent performance in reliability and stability. Furthermore, the surface micromachining is able to fabricate various optical devices, hinges and latches for integrating with micro bench. Therefore, the proposed microoptical bench is potential in optical applications.

Biological fixed-film reactors(FFRs)is a very efficient and cost effective biological wastewater treatment technology . The FFR system we employ is an aerated packed-bed vessel containing an adherent(immobilized)microbial consortium. The cell mass is retained directly on and in the packing media by attaching to the packing’s fixed , solid surfaces to form a layer called the biofilm . The packing media in the FFR consists of a mixture of two plastic support systems . The use of mixed media facilitates high rates of oxygen , nutrient and pollutant transfer to and from the biomass . One packing support is a polyurethane foam(PUF)which allows a high concentration of immobilized biomass to develop . The other packing support consists of large-pore packing which is used to eliminate the problems of plugging and channeling, a major concern with other fixed-film systems , The FFR is designed as a quasi-plug flow system to minimized back-mixing and thus provide extremely low effluent pollutant concentrations . A fixed-film reactor system was constructed with a highly porous polyurethane foam to incubate microorganism concentration up to 8,000 mg/L . The support frame of the reactor system was build from cylindrical plastic pall rings to form a packed bed of “mixed-media.” The frame support provides a high surface area-to-volume ratio (210 ft2 / ft3) . The bench-top FFR studies clearly demonstrated the highly effective nature of this fixed-film reactor for degrading the pollutants . The study for refinery wastewater treatment by bench-top fixed-film biological system could demonstrated the highy effective for degrading the pollutions at hydraulic retention time (HRT) of 2 ~3 hours .

As manufacturing technology advances, investment in the construction of wafer FAB is large. In the past, to build an 8” FAB requires NTD 30 billion yuan, and now to build a 12” FAB requires at least NTD 100 billion yuan. Among the investment in the semiconductor industry, the expenditure for the purchase of machine equipment is the highest, accounting for about 60% to 70%. As purchasing second-hand equipment can reduce costs for factory Construction and depreciating machines, competitive advantage can be enhanced. However, it is difficult for the buyers to control the durability and safety of second-hand equipment, particularly the material of the wet bench in the past is mostly polypropylene (PP) or polyvinyl chloride (PVC). They are all flammable, and when burnt, high heat and large amount of smoke will be produced. Moreover, there are heating devices and flammable chemicals inside the machine, so it’s very easy to catch fire in the past, and the loss is also very serious. Therefore the wet bench areas are regarded as the focus of fire protection by all factories. This study takes a model of wet bench equipment in the 8” FAB as the object for assessment, discussing risks in safety and fire of running many-year-old machines through the risks in the machines’ internal tank, electrical units, chemical supply, as well as the material hardware, safety protection and interlocking devices.

There are many domestic and international flight accidents in recent years. The most important part of aviation security includes excellent maintenance and high-efficiency equipment properly rate. This thesis focused on test bench maintenance. The logistics maintenance units (LMU) make these device failures to repair that contain the examination, adjustment and maintenance in the minimum time. According to the previous equipment failure rate and repair demands, the LMU adopts warning strategies to regularly make up accessories. In order to save more manpower and material costs, this thesis systematizes the maintenance allocations as the goals. Due to the traditional radar communication test bench had some drawbacks, including the high-complexity weapon components and small individual amount. Besides, the maintenance and calibration needs severely exceeded the unit loading. This thesis established an evaluation mode applying K.J. card sorting and Analytic hierarchy process (AHP). This evaluation mode could be the reference for the outsourcing vendor warranty of test bench. Moreover, this model improved the equipment maintenance of radar communication test bench and extended its useful life to reduce the military maintenance cost.

An experiment in hydraulic model test, investigating the deformation of the wave field caused by irregular wave passing through submerged breakwater. The experiment is designed by comparing measurements obtained under three different incident wave angles(θ=0∘、15∘、30∘), four different significant wave periods (T1/3=1.00、1.25、1.50、1.75sec), and two submerged breakwaters of different width (b=1.0、2.0m). We thus discuss the variation in wave deformation, wave heights and time period changes in the areas surrounding the submerged breakwaters, and the refraction and diffraction effects caused by irregular wave passing through. The experiments reveal that different submerged breakwaters differ in its response to irregular wave encountering, and therefore resulting in a more obvious reflection effect of incident waves. The distribution of change in significant wave heights shifts in consistent with the direction of incident waves. The difference in width of submerged breakwaters affects the distribution of larger significant wave heights behind the submerged breakwaters. The distribution of time period variations also shifts along the direction of incident waves, and expands its distribution area of shorter time period over the time period of the incident waves.

Inherited renal tubular disorders are characterized by muscle weakness, exertional intolerance, polyuria, convulsion, short stature, and rickets during childhood. The main biochemical abnormalities include dysnatremia, dyskalemia, dyscalcemia, metabolic acidosis and metabolic alkalosis. The modes of inheritance could be autosomal recessive, autosomal dominant, X-linked recessive or X-linked dominant. Because the major inheritance is autosomal recessive and the initial presentations are insidious, it is difficult to make an early diagnosis of inherited renal tubular disorders. However, it leads to growth retardation, renal failure and even death from delayed diagnosis or treatment. In recent years, we have diagnosed several inherited renal tubular disorders including Gitelman’s syndrome, Bartter’s syndrome, renal fanconi syndrome results from LOWE syndrome, Dent’s disease, and mitochondrial disorder, familial hypomagnesemia hypercalciuria nephrocalcinosis, nephrogenic diabetes insipidus, and autosomal recessive renal tubular dysgenesis by molecular analysis. The improvement of clinical conditions of most of our patients was achieved after timely diagnosis and appropriate treatment. In chapter 1, we presented a child with hereditary vitamin D-resistant rickets (HVDRR) caused by a novel mutation on RXR domain of vitamin D receptor gene. This child exhibited hypocalcemia, hypophosphatemia, secondary hyperparathyroidism, increased serum 1,25-dihydroxyvitamin D3, rickets and alopecia. Although patients with mutations in different binding domains have been shown to exhibit distinct and variable severity of phenotypes, the study of the VDR mutant on RXR-binding domains remains limited. Therefore, we conducted a functional study was performed to explore the molecular mechanism in vitro to aid in understanding the pathogenesis of HVDRR. In chapter 2, mutations in SLC12A3 encoding the thiazide-sensitive sodium chloride cotransporter on the apical membrane of distal convoluted tubule lead to Gitelman’s syndrome. We attempted to investigate the genotype, phenotype and follow-up of Taiwanese with Gitelman syndrome. In chapter 3, Autosomal recessive renal tubular dysgenesis is caused by genetic defects on AGT, REN, ACE or AT1R and is characterized by absence or poor-differentiated proximal convoluted tubules. Recently, we firstly identified five patients of ARRTD caused by identical homozygous large deletion of AGT gene from four unrelated families within 3 year in Taiwan. We will explore the pathogenic role of roles of our defected AGT on the development of renal tubular dysgenesis.
