投資型商品是近幾年來壽險業的新興戰場，壽險經營者不但對投資型商品未來的發展深具信心，也對多元通路銷售投資型商品抱持樂觀其成以及積極促成的態度；但主管機關雖針對熱絡的投資型商品市場陸續推出（修正）相關規範，卻並未使得日漸升高的申訴率得以降溫，本研究擬就投資型商品通路與申訴率問題探討壽險經營者以及主管機關可調整改善的方向。 各通路銷售投資型商品有其不同的特性與優勢，目前業者仍以業務大軍以及銀行保險（理財專員）為銷售投資型商品的主要通路；而以金管會保險局的申訴統計資料分析後也歸納出三點重要的結論：（1）自引進投資型商品以來，壽險業非理賠類的申訴率就居高不下；（2）近三年來，越是以投資型商品為主力商品的業者其申訴率（非理賠類）也相對較高；（3）以多元化通路（銀行理財專員、保險經紀人）銷售投資型商品的業者其申訴率也較僅以業務人員通路銷售投資型商品的業者為高。 現行投資型商品申訴的問題多與資訊不對稱以及銷售誤導相關，因此，建議壽險業者應從商品規劃以及銷售管理上預防投資型商品申訴問題的發生；主管機關則應從投資型商品銷售通路特性與問題訂定相關的監理規範，才能有效匡正不當銷售的問題。也唯有健全此市場的經營、提升壽險業正面的品牌形象及改善社會大眾對投資型商品負面的觀感，投資型商品市場才有更長遠經營的希望。 / Investment-linked product is becoming a popular insurance product in the recent years. Many insurance companies holds great confidence in the development of this product, and encourages the growing sales of investment-linked product thru multiple channels. The governing authorities continuously publishing new regulations or making amendments to better manage the product and the process. However, the statistics showed regulatory requirements did not help to reduce the investment-linked product compliant ratio. By analyzing the sales channels and complaint ratio, this study wishes to put forward recommendations for the governing authorities and the insurers to improve the complaint ratios. Different sales channel is characterized by its specialty and strength. Currently, investment-linked products are being sold thru agency and bancassurance channels. According to the publicly released statistic of insurance compliant by Insurance Bureau of Financial Supervisor Committee (FSC), there are three main issues: 1.Non-claim compliant ratio remains high since the inception of investment-linked product. 2.In the recent three years, insurance companies whose sales are mostly investment-linked product have higher ratio of non-claim compliant. 3.Bancassurance and brokerage channels experience higher ratio of non-claim compliant comparing to agency channel when selling investment-linked product. Complaints of investment-linked product in the life insurance companies mostly resulted from improper selling and misrepresented or misleading information. Thus, suggestions for insurers and the governing authorities are followed: 1.For insurers, they have to revisit their product design methodology, and also need to manage and educate each channel to prevent the occurrence of insurance compliant. 2.For authorities, the regulatory focus should be channel specific since channels operate differently. Only when improper selling and misrepresenting issues are being addressed, and customer’s image for investment-link product being corrected, then we can see light and hope in the growing needs of investment-linked product.

Charles University in Prague Faculty of Law Abstract of the dissertation The title of the dissertation: Sharia Law, particularly Islamic banking, in relations with international elements Author: JUDr. Ivana Hrdličková Supervisor: Prof. JUDr. Monika Pauknerová, CSc., DSc. Prague, February 2012 Key words: Islamic finance, sharia, mudaraba, musharaka, murabaha, ijara, sharia compliant, international law, choice of law, contract, riba, gharar, maisir. The dissertation, Sharia law, particularly Islamic Banking in the relations with international elements, considers an actual topic and branch of islamic law. Neither islam nor islamic law is a legal system applicable at any particular territory. However, legislation of the countries with majority of muslim population, is based, more or less, on islamic law. Whereas due to migration and globalization, islamic law unavoidably interferes in international law. The legal regulation of international private law under the terms stipulated by the law leads to the use of foreign law. One can thus meet the legislation based on islamic law, including in the field of contract law. In commercial contracts, where the one side is from countries where islamic law is a source of legislation, may be the choice of law (in accordance with article 3 of Rome I), which form's the basis...

La commande des actionneurs électropneumatiques a été un sujet largement traité au cours des dernières décennies. Le caractère fortement non-linéaire de son comportement en a fait un cas d'étude particulièrement pertinent dans le cadre d'une démarche d'application de la théorie de la commande des systèmes non-linéaires. L'utilisation de ces techniques a été comparée aux approches linéaires traditionnelles et généralement jugée largement supérieure notamment en termes de précision ou de temps de réponse. Dans ce manuscrit nous abordons très spécifiquement l'aspect multivariable du système et introduisons la transformée A-T, similaire à la transformée de Park appliquée classiquement aux systèmes électriques, afin de donner une forme strict feedback à son modèle d'état, de clarifier les phénomènes physiques mis en jeu lors de sa commande et de distinguer les deux degrés de liberté du système. Cette transformée permet en outre une comparaison directe avec les moteurs électriques décrits dans le repère de Park. Ce parallèle rend notamment possible la solution du problème délicat de l'observation de la position à vitesse nulle en transférant des méthodologies déjà validées sur des systèmes électriques. L'exploitation des deux degrés de liberté est illustrée par la synthèse de lois de commande combinant le suivi d'une trajectoire de position du piston au respect d'un second critère variable (réglage de la pressurisation moyenne, optimisation de la consommation instantanée). L'utilisation d'un actionneur électropneumatique asservi comme actionneur à compliance variable est étudiée. Une loi de commande basée sur la transformée A-T est proposée pour contrôler simultanément la position et la raideur pneumatique de l'actionneur. Une méthodologie de réglage des gains de commande est proposée pour définir l'impédance en boucle fermée du système. L'influence de la raideur pneumatique sur la raideur en boucle fermée est étudiée. L'utilisation d'une source d'énergie alternative (de l'hélium sous pression) est également pour la première fois mise en œuvre. L'influence du changement de gaz sur le dimensionnement de l'actionneur électropneumatique est étudiée et une méthodologie permettant d'utiliser les lois de commande prévues pour de l'air est proposée. L'ensemble des propositions faites dans ce manuscrit est testée et validée sur un banc d'essais à la structure inédite. Ce dernier allie deux actionneurs, l'un électropneumatique (l'actionneur étudié) et l'autre, un moteur plat électrique (l'actionneur de charge). L'utilisation de celui-ci permet la génération d'efforts perturbateurs dans une large bande passante ainsi que la modification en temps réel des paramètres mécaniques dynamiques de la charge. / Control of electropneumatic actuator is a subject which has been thoroughly dealt with in the past decades. The strongly non-linear behavior of those systems made them a particularly relevant case study for applications of the non linear control theory. The use of those techniques has been compared to the traditional linear approaches and is generally considered as more efficient in terms of precision and response time. In this work, we specifically deal with the multivariable character of this actuator and we introduce the A-T transformation, similar to the Park Transformation used for electrical systems study, in order to give a strict feedback form to its state model, clarify the physical phenomena occurring during its control and distinguish the system's two degrees of freedom. This transformation allows a comparison with electrical motors described in the Park's frame. This parallel allows to solution the complex problem of zero speed observation of the piston's position by transferring the methodologies which have been previously used on electrical systems. The utilization of the two degrees of freedom is illustrated by the synthesis of control law which combines the piston position trajectory tracking with the respect of a given criterion (which can be the pressurization level or the instantaneous gas consummation optimization). The use of an electropneumatic actuator as a variable stiffness actuator (VSA) is studied. A control law base on the A-T transform is proposed in order to simultaneously control the position and the pneumatic stiffness of the actuator. A control gains tuning strategy is proposed to allow the system closed loop impedance tuning. The influence of the pneumatic stiffness over the closed loop stiffness is studied. An alternative energy source (pressurized helium) is also used for the first time. The influence of the change of gas over the actuator sizing is studied and a methodology allowing using control laws designed for air applications is proposed. Every proposition are tested and validated using an innovative test bench with a unique structure. The latter combines two actuators. One is an electropneumatic actuator (the one studied) and the other one is a linear motor (used as the load actuator). The use of the latter allows disturbance generation in a wide bandwidth and the real-time tuning of the load dynamic characteristics. Finally, the tools developed in this PHD are used in order to validate the implementation of an electropneumatic solution to the thrust vector control problem of a nano scale space launcher. Data provided by the CNES (the French National Space Agency) are used to de ne specific requirements and the flight conditions are reproduced on the test bench to assess the solution quality.

The use of optical input/output (I/O) interconnects, in addition to electrical I/Os, is a promising approach for achieving high-bandwidth, chip-to-board communications required for future high-performance gigascale chip-based systems. While numerous efforts are underway to investigate the integration of optoelectronics and silicon microelectronics, virtually no work has been reported relating to testing of such chips. The objective of this research is to explore methods that enable wafer-level testing of gigascale chips having electrical and optical I/O interconnects. A major challenge in achieving this is to develop probe modules which would allow high-precision, temporary interconnection of a multitude of electrical and optical I/Os, in a chip-size area, to automated test equipment. A probe module would need to do this in a rapid, step-and-repeat manner across all the chips on the wafer. In this work, two candidate probe modules were devised, batch-fabricated on Si using microfabrication techniques, and successfully demonstrated. The first probe module consists of compliant electrical probes (10^3 probes/cm^2) fabricated alongside grating-in-waveguide optical probes. The second module consists of micro-opto-electro-mechanical-systems (MOEMS)-based microsocket probes (10^4 probes/cm^2) to interface a chip with polymer pillar-based electrical and optical I/Os. High-density through-wafer interconnects are an essential attribute in both probe substrates for transferring electrical and optical signals to the substrate back-side. Fabrication and characterization of metal-clad, metal-filled, and polymer-filled through-wafer interconnects as well as process integration with probe substrate fabrication are described and numerous possible redistribution schemes are explicated. Chips with optical and electrical I/Os are an emerging technology, and one that test engineers are likely to encounter in the near future. The contributions of this thesis are to help understand and address the issues relating to joint electrical and optical testing during manufacturing.

Quantifying the influence of pressure on the effective elastic rock properties is important for applications in rock physics and reservoir characterization. Here I investigate the relationship between effective pressure and seismic velocities by performing inversion on the laboratory-measured data from a suite of clastic, carbonate and igneous rocks, using different analytic and discrete inversion schemes. I explore the utility of a physical model that models a natural fracture as supported by asperities of varying heights, when an effective pressure deforms the tallest asperities, bringing the shorter ones into contact while increasing the overall fracture stiffness. Thus, the model is known as the ?asperity-deformation? (ADM) or ?bed-of-nails? (BNM) model. Existing analytic solutions include one that assumes the host rock is infinitely more rigid than the fractures, and one that takes the host-rock compliance into account. Inversion results indicate that although both solutions can fit the data to within first-order approximation, some systematic misfits exist as a result of using the rigid-host solution, whereas compliant-host inversion returns smaller and random misfits, yet out-of-range parameter estimates. These problems indicate the effects of nonlinear elastic deformation whose degree varies from rock to rock. Consequently, I extend the model to allow for the pressure dependence of the host rock, thereby physically interpreting the nonlinear behaviors of deformation. Furthermore, I apply a discrete grid-search inversion scheme that generalizes the distribution of asperity heights, thus accurately reproduces velocity profiles, significantly improves the fit and helps to visualize the distribution of asperities. I compare the analytic and numerical asperity-deformation models with the existing physical model of elliptical ?pennyshape? cracks with a pore-aspect-ratio (PAR) spectrum in terms of physical meaning and data-fitting ability. The comparison results provide a link and demonstrate the consistency between the use of the two physical models, making a better understanding of the microstructure as well as the contact mechanism and physical behaviors of rocks under pressure. ADM-based solutions, therefore, have the potential to facilitate modeling and interpretation of applications such as time-lapse seismic investigations of fractured reservoirs.

This thesis deals with the design of two-axis displacement-amplifying compliant mechanisms (DaCMs) using topology optimization. The two-axis compliant mechanisms considered here are XY positioners and two-axis inertial sensors. A building block approach, with several single-axis DaCMs as building blocks, is used to conceive designs of compliant platforms that provide two orthogonal and independent movement of a common platform. Spring-mass-lever (SML) models of these designs are developed to simplify the analysis and design of the complicated arrangements of building blocks. The XY positioners designed in this work have perfectly de-coupled motion without compromising on the frequency; the best design of the stage has a displacement amplification of five resulting in the enhanced range of 4.2 % of the mechanism size–a significant improvement from the 1.67 %, the maximum range of the designs reported so far. Nearly 100% improvement is observed in the sensitivity of the two-axis accelerometer as compared with an existing design that occupied the same area. Multiple prototypes of XY positioners were fabricated on polypropylene sheets using CNC machining; and on spring steel and aluminium using wire-cut electro discharge machining. Mask layouts for two-layer two-axis accelerometers are designed for micro-fabrication using reactive ion etching and wafer bonding.

Flapping-wing micro air vehicle (MAV) is an emerging micro-robotic technology, which has several challenges toward its practical implementation. Inspired by insect flight, researchers have adopted bio-mimicking approach to accomplish its engineering model. There are several methods to synthesize such an electromechanical system. A piezoelectric actuator driven flapping mechanism, being voltage controlled, monolithic, and of solid state type exhibits greater potential than any conventional motor driven flapping wing mechanism at small scale. However, the demand for large tip deflection with constrained mass introduces several challenges in the design of such piezoelectric actuators for this application. The mass constraint restricts the geometry, but applying high electric field we can increase the tip deflection in a piezoelectric actuator. Here we have investigated performance of rectangular piezo-actuator at high electric field. The performance measuring attributes such as, the tip deflection, block force, block moment, block load, output strain energy, output energy density, input electrical energy, and energy efficiency are analytically calculated for the actuator at high electric field. The analytical results suggest that the performance of such an actuator can be improved by tailoring the geometry while keeping the mass and capacitance constant. Thereby, a tapered piezoelectric bimorph cantilever actuator can provide better electromechanical performance for out-of-plane deflection, compared to a rectangular piezoelectric bimorph of equal mass and capacitance. The constant capacitance provides facility to keep the electronic signal bandwidth unchanged. We have analytically presented improvement in block force and its corresponding output strain energy, energy density and energy effi- ciency with tapered geometry. We have quantitatively and comparatively shown the per- formance improvement. Then, we have considered a rigid extension of non-piezoelectric material at the tip of the piezo-actuator to increase the tip deflection. We have an- alytically investigated the effect of thick and thin rigid extension of non-piezoelectric material on the performance of this piezo-actuator. The formulation provides scope for multi-objective optimization for the actuator subjected to mechanical and electrical con- straints, and leads to the findings of some useful pareto optimal solutions. Piezoelectric materials are polarized in a certain direction. Driving a piezoelectric actuator by high electric field in a direction opposite to the polarized direction can destroy the piezo- electric property. Therefore, unipolar high electric field is recommended to drive such actuators. We have discussed the drawbacks of existing switching amplifier based piezo- electric drivers for flapping wing MAV application, and have suggested an active filter based voltage driver to operate a piezoelectric actuator in such cases. The active filter is designed to have a low pass bandwidth, and use Chebyshev polynomial to produce unipolar high voltage of low flapping frequency. Adjustment of flapping frequency by this voltage driver is compatible with radio control communication. To accomplish the flapping-wing mechanism, we have addressed a compatible dis- tributed compliant mechanism, which acts like a transmission between the flapping wing of a micro air vehicle and the laminated piezoelectric actuator, discussed above. The mechanism takes translational deflection at its input from the piezoelectric actuator and provides angular deflection at its output, which causes flapping. The feasibility of the mechanism is investigated by using spring-lever (SL) model. A basic design of the com- pliant mechanism is obtained by topology optimization, and the final mechanism is pro- totyped using VeroWhitePlus RGD835 material with an Objet Connex 3D printer. We made a bench-top experimental setup and demonstrated the flapping motion by actuating the distributed compliant mechanism with a piezoelectric bimorph actuator.

L’objectif de ce travail est d’étendre l’étude locale de la stabilité linéaire des interactions fluide-structure à des domaines peu ou pas encore abordés dans la littérature ; l’influence des interfaces poroélastiques sur les couches limites bidimensionnelles, tridimensionnelles, ou aspirées, ainsi que l’écoulement dans une canopée modélisé par un profil de vitesse réaliste, sont ainsi traités. Les résultats révèlent que dans les couches limites 3D, la compliance réduit le domaine d’instabilité du mode TS dominant mais fait apparaître des modes hydroélastiques ; à l’inverse, la perméabilité stabilise ces derniers tout en déstabilisant l’onde TS, s’apparentant en cela à un amortissement. Sur les ailes en flèche, la transition dépend localement d’instabilités nommées tourbillons Crossflow (CF) d’origine non-visqueuse ; l’effet déstabilisant de la perméabilité sur celles-ci est presque nul tandis que son action positive sur les modes hydroélastiques reste intact, offrant des perspectives prometteuses. Dans le domaine des couches limites aspirées, la quasi-totalité des études publiées reposent sur l’hypothèse d’une perméabilité négligeable et d’une paroi rigide ; or il est démontré ici que la perméabilité (indissociable de la succion) exerce même à faible dose une déstabilisation sur la perturbation dominante et que la compliance (pouvant résulter d’un allègement) provoque l’apparition d’une instabilité absolue. Pour finir, l’attention est portée sur les écoulements dans une canopée -assimilables à des couches de mélange. La stabilité linéaire de l’onde nommée monami ou honami est étudiée sur la base d’un profil de vitesse moyenne réaliste calculé numériquement, puis comparé aux résultats obtenus avec le profil en lignes brisées usuellement employé. L’effet de la force de traînée, communément considéré comme amortissant, se révèle au contraire déstabilisant lorsqu’il est pris en compte dès le calcul du profil de vitesse moyenne. / Local linear stability of fluid-structure interactions is investigated in uncustomary fields such as swept, unswept and asymptotic suction incompressible boundary layers developing over compliant, porous plates –in the limit of small permeability– or relatistically-modeled incompressible flows over a canopy. Results show that compliance has a stabilizing effect on the 3D most instable hydrodynamic mode but allows hydroelastic modes to emerge, which take the form of travelling wave flutter instabilities ; conversely, permeability tends to damp the latter ones but to destabilize the former ones. Transition on swept wings also locally depends on 3D unviscid instabilities called Crossflow vortices, hardly unstabilized by permeability ; this provides promizing outlets, since permeability has still a strong positive effect on 3D hydroelastic modes. In the field of incompressible parallel boundary layer flows with uniform suction through the wall, most of the existing studies are based on the assumption that plate’s porosity and flexibility are negligible. Nevertheless, proof is given here that permeability (linked to suction) exerts a strong destabilizing effect on the Tollmien-Schlichting most instable mode. Besides, compliance (that can result from lightering measures) reveals to provoke an absolute instability that is likely to contaminate the entire domain. Finally, attention is paid to incompressible flows across a canopy, that are similar to mixing layers. Linear stability of the coherent motions called monami or honami is adressed using a relatistically-computed velocity profile, then compared to the results obtained with the customary piecewise linear velocity profile. Then, drag force variations are taken into account as soon as velocity profile computing. The result is that drag happens to have a destabilizing effect on the flow, instead of the commonly admitted damping effect.

It stands for a financial system that follows the sharia (Islamic law), which is guided by ethical principles and social justice. The main prohibition usually linked to Islamic finance is of interest, but there is much more to it. It offers a portfolio of products and services which compete with the ones present in the conventional system, however these preserve the Islamic principles. Despite the global reach, Islamic finance did not set foot in Brazil or Latin America overall as it did in Europe and Asia especially. Therefore, this paper tries do unveil what’s behind this financial system and try to find ways to make it’s introduction in Brazil possible. In order to reach this, a qualitative research guided by the presentation of countries that have introduced Islamic finance, and interviews conducted with main players in Brazil linked to Islamic finance. The results of the research reflected partially the perspective of the academia, the expert, the Brazilian market and the Islamic finance industry, given that each interviewee represented one or more of these categories. This was completed with the overall conclusions drawn from the case studies presented, taking the main lessons form their experience. A coding system was developed to filter and organize the results. In terms of the opportunities Islamic finance has in Brazil, what stands out the most is the strong relation between Brazil and the Arab countries (adopters of Islamic finance), especially in exports, which represent situations in which Islamic finance could be adopted to intermediate the financing. The obstacles preventing this from happening are many, and are mainly linked to the unfamiliarity of the subject in the market and the delicate environment Brazil finds itself in, which is not favorable for new projects or investments. The Islamic finance procedures themselves are complicated and difficult, which makes the introduction process more complex. Given all that, there are many measures that can be taken already in order to incentive the introduction of Islamic finance in Brazil or even conduct some isolated Islamic finance operations. Murabahah is an example of a cost plus contract that can be used by exporters to sell their commodity abroad and sukuk is an alternative method for raising money with certificates backed by assets. These two operations can be adopted by Brazilian companies, however need to be conducted abroad due to regulatory complications. For the long term, having experts and professionals interested in Islamic finance ‘spreading the word’ and digging deeper into the subject in their workplace will open opportunities for the companies they work for and be an incentive for future adoption of Islamic finance by others. Entities also working towards the promotion of the halal (sharia-compliant) industries, which can be considered a fuel for Islamic finance, and tightening the relations between Brazil and the Arab countries, will help close the gap and familiarize both sides with the opportunities available. / As finanças islâmicas têm sido um tema recorrente a nível mundial, chamando a atenção dos muçulmanos e não-muçulmanos. Defende um sistema financeiro que segue a sharia (lei islâmica), que é orientada por princípios éticos e justiça social. A principal proibição geralmente ligada às finanças islâmicas é a dos juros, mas há muito mais para isso. Oferece um portfólio de produtos e serviços que competem com os existentes no sistema convencional, no entanto estes preservam os princípios islâmicos. Apesar do alcance global, as finanças islâmicas não entrar no Brasil nem na América Latina como aconteceu na Europa e na Ásia especialmente. Portanto, este artigo tenta revelar o que está por trás desse sistema financeiro e tentar encontrar maneiras de tornar possível a sua introdução no Brasil. Para alcançar isso, realizou-se uma pesquisa qualitativa orientada pelo estudo de países que introduziram as finanças islâmicas, e entrevistas feitas com os principais atores do Brasil ligados às finanças islâmicas. Os resultados da pesquisa refletiram parcialmente a perspectiva da academia, do ‘expert’ do mercado brasileiro e do setor financeiro islâmico, dado que cada entrevistado representava uma ou mais dessas categorias. Isso foi aprimorado com a junção das conclusões gerais extraídas dos estudos de caso apresentados, tirando as principais lições de suas experiências. Um sistema de codificação foi desenvolvido para filtrar e organizar os resultados. Em termos de oportunidades que as finanças islâmicas têm no Brasil, o que mais se destaca é a forte relação entre o Brasil e os países árabes (praticantes das finanças islâmicas), especialmente nas exportações, que representam situações em que as finanças islâmicas poderiam ser adotadas para intermediar no financiamento. Os obstáculos que impedem que isso aconteça são muitos e estão principalmente ligados à falta de familiaridade com o assunto no mercado e ao ambiente delicado que o Brasil se encontra, o que não é favorável a novos projetos ou investimentos. Os próprios procedimentos das finanças islâmicas são complicados e difíceis, o que torna o processo de introdução mais complexo. Diante disso, há muitas medidas que podem ser tomadas já para incentivar a introdução das finanças islâmicas no Brasil ou mesmo realizar algumas operações financeiras islâmicas isoladas. Murabahah é um exemplo de um contrato de ‘cost plus’ que pode ser usado pelos exportadores para vender suas commodities no exterior e o sukuk é um método alternativo para arrecadar dinheiro com certificados respaldados por ativos. Essas duas operações podem ser adotadas por empresas brasileiras, porém precisam ser conduzidas no exterior devido à complicações regulatórias. Para o longo prazo, ter especialistas e profissionais interessados nas finanças islâmicas, compartilhando seus conhecimentos sobre assunto e explorando mais profundamente o assunto em seu local de trabalho abrirá oportunidades para as empresas para as quais trabalham e será um incentivo para a futura adoção das finanças islâmicas por parte de outros. As entidades que também trabalham para a promoção das indústrias halal (compatíveis com a sharia) – que podem ser consideradas um combustível para as finanças islâmicas – e aprimorando as relações entre o Brasil e os países árabes, ajudarão à reduzir a lacuna e na familiarização dos dois lados com as oportunidades disponíveis.
