Ruzindana, Mark William. "Real-Time Beamforming Algorithms for the Focal L-Band Array on the Green Bank Telescope." BYU ScholarsArchive, 2017. https://scholarsarchive.byu.edu/etd/6622.
Full textAbstract:
A phased array feed (PAF) provides a contiguous, electronically synthesized wide field of view for large-dish astronomical observatories. Significant progress has been made in recent years in improving the sensitivity of PAF receivers though optimizing the design of the antenna array, cryogenic cooling of the front end, and implementation of real-time correlation and beamforming in digital signal processing. FLAG is a 19 dual-polarized element phased array with cryogenic LNAs, direct digitization of RF signals at the front end, digital signal transport over fiber, and a real time signal processing back end with up to 150 MHz bandwidth. The digital back end includes multiple processing modes, including real-time beamforming, real-time correlation, and a separate real-time beamformer for commensal radio transient searches. Following a polyphase filterbank operation performed in field programmable gate arrays (FPGAs), beamforming, correlation, and integration are implemented on graphical processing units (GPUs) that perform parallelized operations. Parallelization greatly increases processing speed and allows for real-time signal processing. During a recent test/commissioning of FLAG, Tsys/efficiency of approximately 28 K was measured across the PAF field of view and operating bandwidth, corresponding to a system temperature below 20 K. To demonstrate the astronomical capability of the receiver, a pulsar (PSR B1937+21) was detected with the real-time beamformer. This thesis provides details on the development of the FLAG digital back end, the real-time beamformer, and reports on the commissioning tests of the FLAG PAF receiver developed by the National Radio Astronomy Observatory (NRAO), Green Bank Observatory (GBO), West Virginia University (WVU), and Brigham Young University for the Green Bank Telescope (GBT).

Diemer, Michael. "Bank Bailouts, Bank Levy, and Bank Risk-Taking." Doctoral thesis, Universitätsbibliothek Leipzig, 2014. http://nbn-resolving.de/urn:nbn:de:bsz:15-qucosa-157041.
Full textAbstract:
This thesis is concerned with the relation between bank regulation and the risk-taking behaviour of banks. Two major instruments of regulatory intervention are considered: bank levy and bank bailouts. The major objective of this thesis is to provide an answer to the following questions: Do bank levies increase the risk-taking of banks in a competitive environment? When do bank bailouts decrease banks` risk-taking? Does the international coordination of bank bailouts affect the relation between bailouts and the risk-taking behaviour of banks? Who should rescue subsidiaries of multinational banks? How could an efficient bailout policy be designed and implemented?
The bank levy and cooperation between national regulators play an important role in the recently adopted Bank Recovery and Resolution Directive (BRRD). This directive is a cornerstone of bank regulation in Europe. Although the conversion of debt into equity (bail-in) in emergencies is the key component of the current regulation, bailouts, or at least the assistance to struggling banks, should not be excluded. As the ordinary resolution tools, for instance, bail-in, have not yet been tested in a real crisis, and due to the fact that it will take time to prepare global institutions for such a tool, it may be useful to have an adequately designed tool of last resort available, such as an adequate bailout policy, in order to avoid the disruption of critical economic functions.
We show that a bank levy may decrease banks`risk-taking behaviour. Bank bailouts can also decrease the risk-taking of banks. This depends on the regulator`s ability to condition his bailout policy in accordance with the macroeconomic environment, which has an impact on the banks` probability of success, or on his ability to condition the bailout policy on the banks` systemic relevance. Coordination of bailouts through a multinational regulator can improve welfare. The desirability of internationally coordinated bailouts depends on the dimension of the crisis. If the crisis is severe, it may be more efficient to delegate bank bailouts to a multinational regulator. However, such a delegation is not always feasible. Therefore, a predefined burden sharing of bank bailouts is necessary in order to achieve an efficient resolution of banks in distress.

La Responsabilidad Social Corporativa (RSC) es un tema de interés en la literatura académica actual y en la gestión empresarial, las empresas están incluyendo cada vez más estos aspectos en su actividad habitual. Concretamente el sector financiero, aunque es de los menos estudiados en la literatura existente, es uno de los que más invierte en materia de RSC a nivel mundial aplicando distintas políticas de responsabilidad social y medioambiental en sus negocios.
Mediante el análisis en profundidad del caso del Banco Santander y utilizando un análisis cualitativo con el soporte de la herramienta del Atlas.ti este trabajo identifica en primer lugar cómo la RSC es integrada en la gestión del negocio bancario del Santander con la finalidad de cubrir las necesidades de los distintos grupos de interés identificados y de mantenerse en una posición de eficiencia financiera y de liderazgo internacional. Una vez analizada la forma de considerar la responsabilidad social dentro del negocio bancario esta investigación también propone analizar la dirección de la relación existente entre RSC y eficiencia. La relación entre la rentabilidad social y la rentabilidad financiera en el sector bancario internacional ha sido ya analizada en la literatura previa, pero en este estudio se utilizará un indicador de RSC y se relacionará mediante regresiones por cuantiles, intercuantiles y xtlogit, con un indicador de eficiencia obtenido previamente con la técnica del DEA, concluyendo en este caso la existencia de una relación bidireccional.
Finalmente, el estudio de las acciones de Responsabilidad Social Corporativa que realizan los bancos permite avanzar en el conocimiento de las inversiones en materia social que realizan las entidades financieras. Medir la relación entre la RSC con la valoración de imagen de la compañía y la satisfacción de los clientes de las entidades financieras es el último objetivo principal que persigue este estudio. La relación entre estos tres constructos se complementará con el análisis multigrupo utilizando tres variables moderadoras: la tipología de cliente, la familiaridad con la entidad y su lealtad con la organización. Partiendo de los datos obtenidos de una muestra de usuarios de entidades financieras se propone un modelo de ecuaciones estructurales utilizando la técnica Parcial Least Squares (PLS). Entre los principales resultados obtenidos se puede concluir que según la evidencia empírica de esta investigación las iniciativas de RSC que desarrollan actualmente las entidades financieras no les producirán un incremento de la satisfacción de sus clientes ni de la imagen de sus entidades en el corto plazo.Corporate Social Responsibility (CSR) is an interesting topic in the current academic literature and business management; companies are increasingly including these aspects in their daily activity. Specifically, the financial sector, although it is the least studied in the literature, It’s one of the most investments in CSR globally applying different policies of social and environmental responsibility in their business. Through in-depth analysis of the case of Banco Santander and using a qualitative analysis with Atlas.ti (analysis tool) this paper first identifies how CSR is integrated into the management of the banking business of Santander in order to cover the needs of different stakeholders identified and maintained in a position of financial efficiency and international leadership. Having analysed the way to consider social responsibility in the banking business this research also aims to analyse the direction of the relationship between CSR and efficiency. The relationship between social profitability and financial profitability in the international banking sector has already been analysed in previous literature, but in this study an indicator of CSR will be used and will be linked by quantile regressions, interquantile and xtlogit, with indicator efficiency previously obtained with the technique of DEA, concluding in this case the existence of a bidirectional relationship. Finally, the study of Corporate Social Responsibility actions by banks allows advance knowledge of investments in social matters performing financial institutions. Measure the relationship between CSR with the image valuation and customer satisfaction of financial institutions is the last main objective of this study. The relationship between these three constructs are complemented by the multi-group analysis using three moderating variables: the type of client, familiarity with the organization and loyalty to the organization. Based on data obtained from a sample of users of financial institutions a model of structural equations using the technique Partial Least Squares (PLS) it is proposed. Among the main results obtained it can be concluded that according to the empirical evidence of this research CSR initiatives currently developing financial institutions will not produce them increased customer satisfaction and image of its entities in the short term.

Full textAbstract:
Motiviert durch das Problem der optimalen Strategie beim Handel einer großen Aktienposition, behandelt diese Arbeit ein stochastisches Kontrollproblem mit zwei besonderen Eigenschaften. Zum einen wird davon ausgegangen, dass das Kontrollproblem eine exponentielle Verzögerung in der Kontrollvariablen beinhaltet, zum anderen nehmen wir an, dass die Koeffizienten des Kontrollproblems linear in der Kontrollvariablen sind. Wir erhalten ein degeneriertes stochastisches Kontrollproblem, dessen Lösung - sofern sie existiert - Bang-Bang-Charakter hat. Die resultierende Unstetigkeit der optimalen Kontrolle führt dazu, dass die Existenz einer optimalen Lösung nicht selbstverständlich ist und bewiesen werden muss. Es wird eine Folge von stochastischen Kontrollproblemen mit Zustandsprozessen konstruiert, deren jeweilige Diffusionsmatrix invertierbar ist und die ursprüngliche degenerierte Diffusionsmatrix approximiert. Außerdem stellen die Kostenfunktionale der Folge eine konvexe Approximation des ursprünglichen linearen Kostenfunktionals dar. Um die Konvergenz der Lösungen dieser Folge zu zeigen, stellen wir die Kontrollprobleme in Form von stochastischen Vorwärts-Rückwärts-Differential-gleichungen (FBSDEs) dar. Wir zeigen, dass die zu der konstruierten Folge von Kontrollproblemen gehörigen Lösungen der Vorwärts-Rückwärtsgleichungen – zumindest für eine Teilfolge - in Verteilung konvergieren. Mit Hilfe einer Konvexitätsannahme der Koeffizienten ist es möglich, einen Kontroll-prozess auf einem passenden Wahrscheinlichkeitsraum zu konstruieren, der optimal für das ursprüngliche stochastische Kontrollproblem ist. Neben der damit bewiesenen Existenz einer optimalen (Bang-Bang-) Lösung, wird damit auch eine glatte Approximation der unstetigen Bang-Bang-Lösung erreicht, welche man für die numerische Approximation des Problems verwenden kann. Die Ergebnisse werden schließlich dann in Form von numerischen Simulationen auf das Problem der optimalen Handels¬ausführung angewendet.Motivated by the problem of how to optimally execute a large stock position, this thesis considers a stochastic control problem with two special properties. First, the control problem has an exponential delay in the control variable, and so the present value of the state process depends on the moving average of past control decisions. Second, the coefficients are assumed to be linear in the control variable. It is shown that a control problem with these properties generates a mathematically challenging problem. Specifically, it becomes a stochastic control problem whose solution (if one exists) has a bang-bang nature. The resulting discontinuity of the optimal solution creates difficulties in proving the existence of an optimal solution and in solving the problem with numerical methods. A sequence of stochastic control problems with state processes is constructed, whose diffusion matrices are invertible and approximate the original degenerate diffusion matrix. The cost functionals of the sequence of control problems are convex approximations of the original linear cost functional. To prove the convergence of the solutions, the control problems are written in the form of forward-backward stochastic differential equations (FBSDEs). It is then shown that the solutions of the FBSDEs corresponding to the constructed sequence of control problems converge in law, at least along a subsequence. By assuming convexity of the coefficients, it is then possible to construct from this limit an admissible control process which, for an appropriate reference stochastic system, is optimal for our original stochastic control problem. In addition to proving the existence of an optimal (bang-bang) solution, we obtain a smooth approximation of the discontinuous optimal bang-bang solution, which can be used for the numerical solution of the problem. These results are then applied to the optimal execution problem in form of numerical simulations.

Full textAbstract:
The next generation satellite communication networks will provide multimedia services supporting high bit rate, mobility, ATM, and TCP/IP. In these cases, the satellite technology will act as the internetwork infrastructure of future global systems and assuming a global wireless system, no distinctions will exist between terrestrial and satellite communications systems, as well as between fixed and 3G mobile networks. In order for satellites to be successful, they must handle bursty traffic from users and provide services compatible with existing ISDN infrastructure, narrowcasting/multicasting services not offered by terrestrial ISDN, TCP/IP-compatible services for data applications, and point-to-point or point-to-multipoint on-demand compressed video services. This calls for onboard processing payloads capable of frequency multiplexing and demultiplexing and interference suppression.
This thesis introduces a new class of oversampled complex modulated filter banks capable of providing frequency multiplexing and demultiplexing. Under certain system constraints, the system can handle all possible shifts of different user signals and provide variable bandwidths to users. Furthermore, the aliasing signals are attenuated by the stopband attenuation of the channel filter thus ensuring the approximation of the perfect reconstruction property as close as desired. Study of the system efficient implementation and its mathematical representation shows that the proposed system has superiority over the existing approaches for Bentpipe payloads from the flexibility, complexity, and perfect reconstruction points of view. The system is analyzed in both SISO and MIMO cases. For the MIMO case, two different scenarios for frequency multiplexing and demultiplexing are discussed.
To verify the results of the mathematical analysis, simulation results for SISO, two scenarios of MIMO, and effects of the finite word length on the system performance are illustrated. Simulation results show that the system can perform frequency multiplexing and demultiplexing and the stopband attenuation of the prototype filter controls the aliasing signals since the filter coefficients resolution plays the major role on the system performance. Hence, the system can approximate perfect reconstruction property by proper choice of resolution.

Full textAbstract:
This paper examines five big band arrangements written during a period of two semesters from 1998-1999. I will provide an overview and performance considerations for each arrangement. Each arrangement uses common conventions such as unison lines, octave doubling, four and five part voicings, found in closed, semi-open, and open position. Approach techniques include diatonic, dominant, diminished, chromatic, and parallel. Choice was based primarily on two considerations: desired texture and the best voice leading options identified to provide each part with a swinging line and maintain melodic integrity. Other conventions applied include chord substitution, upper structure triads, and altered and diminished scales to provide harmonic contrast and color. Each arrangement supplied new challenges and the tunes selected provided the arranger with a diverse experience of styles. The inherent qualities of the melody and harmonic progression of each piece were the primary considerations for selection.

Full textAbstract:
This thesis describes a wide-hand channel sounding experiment carried out at the X-hand frequency over a transhorizon, sea path. The design of a wide-band channel probe is described in detail based upon the following operational requirements. "To capture as many sequential estimates of the transfer function of a telecommunication channel as possible, over the widest possible band-width and in the shortest time, subject to the constraint of low signal-to-noise ratio". The design described includes generation of a specialised, band limited, spectrally clean, synthesized test signal for bandwidth optimisation and the use of real-time, periodic averaging for signal-to-noise ratio enhancement. An external frequency reference has been used in preference to a carrier locked approach. The theoretical justification and hardware implications of this design approach are carefully argued in the thesis. Such a probe has been built, its dynamic performance assessed and compared with more conventional transfer function analyser designs. In particular the frequency stability of the unlocked system configuration and the problem of signal distortion due to excessi ve phase noise are explored in detail. The concept of time domain multi-ray modelling of a telecommunication channel has stimulated the application of high resolution spectral analysis techniques for ray parameter determination. A brief literature survey of various algorithms is presented and a comparison with the conventional Fourier approach is given. Detailed derivation of the Singular Value Decomposition - Prony (SVD-P) algorithm is presented together with an in-depth performance assessment over a wide-variety of simulated channel conditions. The measurement equipment was completed, tested in the laboratory and finally commissioned in May 1993. A long-term data capture campaign was started using an existing cross channel link; a large database of results has subsequently been obtained. Preliminary data analysis has been carried out and the thesis describes the phenomenological characteristics of the channel whilst subjected to a wide range of multipath propagation mechanisms. The final chapter of the thesis highlights the novel achievements of the research, together with a summary of the strengths and limitations of the experimental equipment and processing algorithms.

Full textAbstract:
The research project uses still life as a means of exploring current events of violence and oppression. These events are represented through juxtaposing plastic toys with organic objects. The toys include a range of popular generic toys such as army men, cowboys and Indians and toy soldiers. The organic objects were selected for their relationship to the specific event being represented. The toys and organic objects were positioned to create interesting and logical compositions. Themes of the series include opposing objects and ideas pitched against each other such as plastic/organic, perpetrator/victim, violence/peacefulness and destruction/sustenance. Within each work the plastic toys take on the demeanor of the tyrant(s), whereas the organic objects adopt the role of the victim(s). The research project uses these themes to convey the message that violence is both a barbaric way of dealing with conflict and a senseless form of self-expression. I have used symbols and metaphors to build a visual language. For the language to be translated accurately a great deal of research has taken place into the appropriate still life objects for each work. Each work incorporates metaphors and or symbols for both the oppressor and victim within the event being represented. The studio outcome of this research project, Silent Bang, includes a series of highly detailed finished paintings of various scales. Silent Bang as a body of work is colourful and aims to be aesthetically pleasing in addition to conveying a powerful message that incites interpretation.

[Parte I] Concentración AFE: estratégico y de mercados -- [Parte II] Concentración AFE organizativo - financiero.
Para el mundo de los negocios resultan bastante lejanos los cómics. Sin mucho espacio a duda, para el ejecutivo promedio no deja de ser una atracción pasajera para sus hijos, o tal vez la película de moda para ir a ver el fin de semana y seguramente una actividad propia de “nerds”. Pero cuando nos vamos interiorizando, y podemos observar por ejemplo, que el título más vendido de la historia, The Amazing Spiderman N° 583 (Sí el número 583, se vende hace casi 50 años!) vendió sólo en Estados Unidos, durante enero y febrero de 2009, más de 530 mil unidades, reportando para Marvel, la editorial dueña de los derechos, más de 2 millones de dólares, la percepción cambia y ya no resulta tan insignificante. Ahora bien, cualquier observador inexperto diría fácilmente, “pero esos datos son de Estados Unidos y no tienen nada que ver con nuestra realidad”, no deja de tener razón. Es evidente que nuestro país para cualquier negocio es menor, especialmente si es de nicho. No obstante, resulta llamativo que según la biografía revisada1 al año 2011, el 1% de la población nacional lee comics diariamente. Siendo conservadores, ya que aquel estudio no tenía ese fin, y considerando solo la ciudad de Santiago, el tamaño del mercado es superior a 70 mil personas. Según la encuesta que realizamos para conocer más de ellos, gastan cerca de $ 1.000 millones de pesos al año. Pero, ¿Que podríamos hacer distinto para captar la atención en este mercado? La verdad es que en Santiago no sería tan difícil. Fanáticos y aficionados del cómic solo son atendidos por 8 tiendas “especialistas”, que a la luz de una visita presencial a cada una de ellas, y según la confirmación que nos dieron los resultados de nuestra investigación, tienen características que no se condicen con lo que ellos quieren: atención deficiente, poca variedad de títulos y mala ubicación. En consecuencia, la idea de Comics Bang! es ofrecer una propuesta distinta a lo que hay en la actualidad en el mercado, poniendo a disposición de los consumidores la posibilidad de arrendar comics y participar de una batería de actividades ad hoc, en un espacio acogedor y tecnológico, para mejorar y hacer más llamativa la experiencia en la tienda. Con personal experto, pero amable y cercano, con mayor variedad de títulos disponibles de los que tienen en sus estanterías la competencia relevante y una ubicación ideal en pleno corazón de Providencia (en Calle Suecia a pasos del metro Los Leones) de fácil acceso y en un barrio comercial. Comics Bang! tiene una clara estrategia de diferenciación, donde sus esfuerzos y capacidades están dirigidos a dos públicos: el experto en cómics, que ya tiene un camino en este mundo y que prefiere comprar los títulos y participar de actividades periódicamente, pero también al principiante, que ve en el arriendo una oportunidad para aumentar su capacidad de leer títulos y conocimiento. Se pretende construir una relación con el cliente vinculante a través de la página web y de las redes sociales y por esta vía se intenta conseguir posicionamiento de marca y dar a conocer los atributos de la tienda. A pesar de que el equipo de trabajo será reducido, contaremos de manera ineludible con un Community Manager para enfatizar el interés de la empresa en darse a conocer y marcar tendencia en este ámbito. Respecto a la composición de la industria, no existen amenazas importantes y si ellas se materializaran, creemos contar con las habilidades y recursos suficientes para afrontarlas y superarlas. El equipo gestor cuenta con expertos en cómics, con el bagaje de haber trabajado en los distintos estamentos del negocio. La evaluación económica financiera del negocio considera un horizonte de cinco años para todas las proyecciones, teniendo como resultados relevantes para un inversión de 178.846.706 millones de pesos, un VAN de $268.008.621, con una TIR de 41,45%. Estos datos nos permiten concluir que es absolutamente recomendable llevar a cabo el proyecto, tenemos la convicción que la rentabilidad proyectada es sostenible y suficientemente atractiva para quienes deseen invertir en un emprendimiento no convencional pero seguro.

Norouzian, Fatemeh. "Dual-band and switched-band highly efficient power amplifiers." Thesis, University of Birmingham, 2015. http://etheses.bham.ac.uk//id/eprint/5865/.
Full textAbstract:
The Power Amplifier is the most challenging module of a wireless network to design and it is the highest power consumer. Lots of research has been dedicated to design highly efficient and linear power amplifiers. The high demand for wireless communication systems creates the requirement for multiband transmitters and receivers. Providing high efficiency for power amplifiers in multiband applications is even more challenging. The work presented in this thesis is focused on designing high efficiency frequency adaptive power amplifiers. Frequency adaptive power amplifiers are categorized in three groups: broadband, multi-band and switched-band power amplifiers. Two main design methodologies of frequency adaptive power amplifiers are proposed in this thesis. They are dual-band and switched-band power amplifiers. The advantages and limitations of their output performances are evaluated. The main goals in this thesis are achieving high efficiency and required output power over all working bands and maintaining consistent performance over the bandwidth. In the dual-band power amplifiers, the distributed matching network is designed without any switches. Both of the switched-band Class-E power amplifiers have switched shunt capacitor values. The results demonstrate the tradeoffs between achieving consistent high performance in each band and introducing losses and complexity in the switching design.

Quantum bang-bang control is a method of suppressing decoherence in qubits [VKL99, VL98]. To date, mathematically rigorous treatments of quantum bang-bang control offered little intuition. To complement existing approaches and to seek better understanding, I present intuitive pictures to think about quantum bang-bang control. In addition, I develop a formalism for treating phase noise moments of a qubit under quantum bang-bang control. Although the desired purpose of quantum bang-bang control is to remove noise, it is conceivable that it can be used to infer information about the noise process and coupling on a qubit. By using a simple random rotation model of single qubit dephasing, I demonstrate how quantum bang-bang control can distinguish between dephasing under different stochastic processes. I also show how quantum bang-bang control can determine noise coupling in a toy model where noise couples to the qubit via a fixed noise axis. These two demonstrations indicate the potential of quantum bang-bang control as a tool for qubit noise spectroscopy.

Doutoramento em MatemáticaConsideramos o problema de controlo óptimo de tempo mínimo para sistemas de controlo mono-entrada e controlo afim num espaço de dimensão finita com condições inicial e final fixas, onde o controlo escalar toma valores num intervalo fechado. Quando aplicamos o método de tiro a este problema, vários obstáculos podem surgir uma vez que a função de tiro não é diferenciável quando o controlo é bang-bang. No caso bang-bang os tempos conjugados são teoricamente bem definidos para este tipo de sistemas de controlo, contudo os algoritmos computacionais directos disponíveis são de difícil aplicação. Por outro lado, no caso suave o conceito teórico e prático de tempos conjugados é bem conhecido, e ferramentas computacionais eficazes estão disponíveis. Propomos um procedimento de regularização para o qual as soluções do problema de tempo mínimo correspondente dependem de um parâmetro real positivo suficientemente pequeno e são definidas por funções suaves em relação à variável tempo, facilitando a aplicação do método de tiro simples. Provamos, sob hipóteses convenientes, a convergência forte das soluções do problema regularizado para a solução do problema inicial, quando o parâmetro real tende para zero. A determinação de tempos conjugados das trajectórias localmente óptimas do problema regularizado enquadra-se na teoria suave conhecida. Provamos, sob hipóteses adequadas, a convergência do primeiro tempo conjugado do problema regularizado para o primeiro tempo conjugado do problema inicial bang-bang, quando o parâmetro real tende para zero. Consequentemente, obtemos um algoritmo eficiente para a computação de tempos conjugados no caso bang-bang.
In this thesis we consider a minimal time control problem for single-input control-affine systems in finite dimension with fixed initial and final conditions, where the scalar control take values on a closed interval. When applying a shooting method for solving this problem, one may encounter numerical obstacles due to the fact that the shooting function is non smooth whenever the control is bang-bang. For these systems a theoretical concept of conjugate time has been defined in the bang-bang case, however direct algorithms of computation are difficult to apply. Besides, theoretical and practical issues for conjugate time theory are well known in the smooth case, and efficient implementation tools are available. We propose a regularization procedure for which the solutions of the minimal time problem depend on a small enough real positive parameter and are defined by smooth functions with respect to the time variable, facilitating the application of a single shooting method. Under appropriate assumptions, we prove a strong convergence result of the solutions of the regularized problem towards the solution of the initial problem, when the real parameter tends to zero. The conjugate times computation of the locally optimal trajectories for the regularized problem falls into the standard theory. We prove, under appropriate assumptions, the convergence of the first conjugate time of the regularized problem towards the first conjugate time of the initial bang-bang control problem, when the real parameter tends to zero. As a byproduct, we obtain an efficient algorithmic way to compute conjugate times in the bang-bang case.
On considère le problème de contrôle optimal de temps minimal pour des systèmes affine et mono-entrée en dimension finie, avec conditions initiales et finales fixées, où le contrôle scalaire prend ses valeurs dans un intervalle fermé. Lors de l'application d'une méthode de tir pour résoudre ce problème, on peut rencontrer des obstacles numériques car la fonction de tir n'est pas lisse lorsque le contrôle est bang-bang. Pour ces systèmes, dans le cas bangbang, un concept théorique de temps conjugué a été défini, toutefois les algorithmes de calcul direct sont difficiles à appliquer. En outre, les questions théoriques et pratiques de la théorie du temps conjugué sont bien connues dans le cas lisse, et des outils efficaces de mise en oeuvre sont disponibles. On propose une procédure de régularisation pour laquelle les solutions du problème de temps minimal dépendent d’un paramètre réel positif suffisamment petit et sont définis par des fonctions lisses en temps, ce qui facilite l’application de la méthode de tir simple. Sous des hypothèses convenables, nous prouvons un résultat de convergence forte des solutions du problème régularisé vers la solution du problème initial, lorsque le paramètre réel tend vers zéro. Le calcul des temps conjugués pour les trajectoires localement optimales du problème régularisé est standard. Nous prouvons, sous des hypothèses appropriées, la convergence du premier temps conjugué du problème régularisé vers le premier temps conjugué du problème de contrôle bang-bang initial, quand le paramètre réel tend vers zéro. Ainsi, on obtient une procédure algorithmique efficace pour calculer les temps conjugués dans le cas bang-bang.

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICONeste trabalho são examinados métodos de codificação de imagens em sub-bandas utilizando quantização vetorial inter-bandas para faixas abaixo de 1 bit/pixel. O espectro de freqüências da imagem é decomposto em 16 sub-bandas uniformes através de um banco de filtros espelhados em quadratura bi-dimensionais. As amostras dos sinais das 16 sub-bandas são usadas para compor um vetor de 16 componentes que, posteriormente, é codificado por um esquema de quantização vetorial (QV). Com o objetivo de reduzir a complexidade e o espaço de memória, são investigadas duas estruturas de quantização vetorial. Uma delas utiliza QV particionada, com o objetivo não só de reduzir a complexidade, como também de explorar as propriedades espectrais. A outra realiza a quantização vetorial direta, enquanto a complexidade é reduzida significativamente. Resultados de simulações são apresentados para as taxas de 0,50 bit/pixel, 0,63 bit/pixel e 0,75 bit/pixel. Uma análise comparativa mostra que o desempenho dos dois esquemas é comparável ao que utiliza quantização vetorial direta, enquanto a complexidade é reduzida significativamente. Resultados de simulações mostram ainda que, a taxas abaixo de 1 bit/pixel, não é recomendável o uso de QV inter-bandas particionada com alocação de bits adaptativa, nem de QV inter-bandas multi-estágios com busca em árvore. A técnica QV inter-bandas quando a sub-banda dominante é codificada separadamente através de um quantizador vetorial intra-banda. Considera-se a decomposição do espectro de freqüências em 16 sub-bandas uniformes e em 13 sub-bandas. Para a decomposição em 16 sub-bandas, esse esquema apresenta desempenho comparável à QV inter-bandas direta e complexidade equivalente à QV inter-bandas multi- estágios.
In this thesis sub-band coding of images using inter-band vector quantization is examined at rates below 1 bit/pixel. The image spectrum is decomposed into 16 uniform bands using 2-D separable quadrature mirror filters. These 16 bands are used to create 16-dimension vectores, which are coded using vector quantization (VQ). In order to reduce the computational complexity and the storage requirements, two vector quantization structures are considered. One approach is to split the vectors not only to reduce complexity but also to exploit spectral properties of the data image. In the order approach the vector quantization is done in multiple stages. Simulation results are presented at rates of 0,50 bit/pixel, 0,63 bit/pixel and 0,75 bit/pixel. A comparative analysis shows that the performance of the two systems is comparable to the basic coding structure, while the complexity is significantly reduced. Simulation results also show that split VQ with adaptive bit allocation and multi-stage VQ with tree search are not recommended at these rates. The best trade-off between complexity and performance is achieved with the inter-band multi-stage VQ scheme using the sequential search procedure. At last, the use of inter- band VQ is examined when the dominant sub-band is separately coded using intra-band VQ. When the image spectrum is decomposed into 16 bands, this scheme has a performance comparable to the basic coding structure while the complexity and storage reduction is equivalent to the inter-band multi-stage VQ technique.

This work studies the effect of mechanically applied uniaxial strain on reverse-bias band-to-band tunneling current in n+/p+ vertical silicon diodes fabricated on {100} and {110} substrate orientations. The Band Structure Lab and nextnano are used to analyze the change in band structure with uniaxial stress applied perpendicular to the tunneling direction along <100> and <110> crystal directions. A theoretical analysis based on the Wentzel-Kramers-Brillouin (WKB) approximation for tunneling probability combined with an uncoupled full-band Poisson equation solver and the calculated band structure changes is developed to model the experimental results. Reasonable agreement between experimental data and theoretical calculations is found when comparing the relative change in tunneling current at 1 V reverse-bias versus strain for different substrate orientation/strain configurations.

Full textAbstract:
Following the opening chapter, which surveys existing literature on the transparency of central bank communication, the remaining chapters each address a simple question to better understand central bank communication, and its effects on financial markets using the European Central Bank (ECB) as a case study. Specifically: o How informative is ECB communication. Chapter 2 provides a glossary that translates explicitly the qualitative information of ECB President monthly press conferences into an ordered scale. We show that the predictive ability of these statements is similar to market-based measures of monetary policy expectations. Moreover, we find that ECB words provide complementary information to macroeconomic variables. o Is it possible to measure objectively qualitative statements. Chapter 3 uses Alceste, textual-content analysis software, to categorize each ECB announcement. We find that these categories explain the volatility of financial market expectations of future monetary policy, but are not statistically helpful in predicting future policy actions. o Is the ECB transparent about its monetary policy framework. Chapter 4 proposes an indirect test of transparency. By looking at ECB explanations of its monetary policy decisions we identify new measures of euro area economic activity and price stability. Then, we use these macroeconomic variables to estimate an ECB-specific empirical reaction function, which better forecasts its future actions compared to standard Taylor-type rules. o Do financial intermediaries understand and believe ECB statements. The final chapter shows that innovations in market expectations about future monetary policy can be explained by unexpected ECB announcements. Hence, we conclude that even if the ECB is a relatively young multinational financial institution, it has already acquired a reputation for telling the truth. Moreover, in order to describe properly its monetary policy we need two dimensions: both the current policy rate and its planned future path.

McIntosh, Damion. "Bank CEO Compensation, Bank Risks and the Financial Crisis Effect." OpenSIUC, 2011. https://opensiuc.lib.siu.edu/dissertations/417.
Full textAbstract:
The market consensus during the financial crisis was that financial sector CEOs were engaged in excessive risk taking induced by compensation practices. Thus, the primary focus of this paper is to determine whether empirical evidence supports this assertion. As such, I examine bank CEO compensation, bank risks, and the relation between bank CEO risk taking incentives and bank risks and the effect of the 2007/9 financial crisis on this relation. I find that banks on average reduced their exposure to credit, capital, total, and unsystematic risks, and increased their exposure to liquidity, portfolio, off-balance sheet and (accounting) foreign exchange risks, from 2003 to 2006. These trends largely reversed during 2007 to 2009. During the 2007/9 financial crisis, banks experienced significant structural shifts in all risk indicators (except for capital and foreign exchange risks) which increased significantly consequent on the economic downturn. I also find that banks remained highly sensitive to changes in short- and long-term interest rates and foreign exchanges rates throughout the period. My findings also support a bank size effect. I observe consistent real growth in CEO base salary annually, from 2003 to 2009, which suggests that there is resilience in this form of compensation to the financial crisis. However, only small banks paid significantly higher base salary during the financial crisis to offset the similar decline in annual bonus payments caused by deteriorating financial and market performances during that time. I find that CEO portfolio option values were more responsive to changes in total risk during the pre-financial crisis period (2003 to 2006) than during the financial crisis (2007 to 2009). Also, I find evidence of banks size effects in compensation components, compensation structure and compensation sensitivity. My results are robust to other sample formations and statistical indicators. After adjusting for the simultaneity bias between bank CEOs' risk taking incentives (measured by the sensitivity of CEO option portfolio and pay for performance sensitivity) and bank risks (using accounting and market based measures), my findings reveal significant shifts in the relation between compensation and bank risks during the financial crisis. Specifically, during the financial crisis, CEOs with more sensitive pay for performance were related to banks with greater capital risk, and banks with higher portfolio risk had CEOs with more sensitive pay for performance. Also, banks with greater total and unsystematic risks during the financial crisis had CEOs with less risk taking incentives. Other indicators during the financial crisis show that less stable banks had CEOs with less risk taking incentives, while banks with greater asset return risk had CEOs with less sensitive option portfolios. Overall, these results do not support the risk inducing incentives of bank CEO compensation especially during the financial crisis.

Uppsatsens syfte är att undersöka hur fan-aktivistiska praktiker online kan skapa gemenskap bland fans och bidra till social förändring för hbtq-personer. Genom att använda kvalitativ innehållsanalys fördjupar jag mig i åtta artiklar som analyserar fansens engagemang, gemenskap och praktiker, relationen mellan producent och fans samt begreppet bury your gays. Då jag positionerar mig inom fältet fanstudier betraktar jag publiken som en aktiv och kreativ aktör. Det speglar även mina teoretiska perspektiv där jag utgår från begreppen medborgarskap, identitet och publikens taktiker kontra producenternas strategier. Resultatet av studien visar att fansen kollektivt kunde skapa en långvarig och handlingskraftig rörelse för att belysa hbtq-frågor. Då konvergensen och fankulturen utvecklats tillsammans kunde fans förlänga producenternas kulturproduktion och ge utrymme för egenproducerat material som även stärkte fansens identiteter. Slutsatsen blir att producenter har makt över mediet då de kan definiera och konstruera normer men det innebär också att publiken har kontroll över sitt eget formade och tolkande av innehållet.The purpose of the essay is to investigate how fan activist practitioners online can create community among fans and contribute to social change for LGBTQ people. By using qualitative content analysis, I examine eight articles that analyze fans' involvement, community and practices, the relationship between producer and fans, as well as the concept of bury your gays. When I position myself in the field of fan studies, I consider the audience as an active and creative participant. My analysis also reflect my theoretical perspectives, assuming the concepts of citizenship, identity and the audience's tactics versus the producers' strategies. The result of the study shows that fans could collectively create a long-lasting and effective movement to highlight LGBTQ issues. When convergence and fan culture developed together, fans could prolong producers' culture production and provide space for self-produced material that also strengthened their identities. The conclusion is that producers have power over the medium as they can define and construct norms, but it also means that the public has control over their own form and interpretation of the content.

Cette étude présente une reconstruction du fonctionnement sédimentaire au Quaternaire de deux pentes carbonatées des Bahamas (leeward et windward). Elle est basée sur les analyses stratigraphique et sédimentaire de 34 carottes principalement collectées lors de la mission CARAMBAR (2010). Une étude stratigraphique à haute résolution a été développée à partir de plusieurs outils stratigraphiques, dont l’écostratigraphie basée sur les assemblages de foraminifères planctoniques qui a permis de dater l’ensemble des séquences sédimentaires en s’affranchissant des problèmes liés à la diagenèse précoce. L’analyse sédimentaire des carottages a permis de proposer une nouvelle classification des sédiments carbonatés meubles qui caractérise les fractions dominantes du sédiment au moment du dépôt. Elle permet notamment de discriminer les dépôts fins et d’identifier les processus de transport off-bank, les dépôts contouritiques, gravitaires ou légèrement diagenétisés. Les processus de transport off-bank permettent l’accumulation de boue carbonatée de plate-forme (aiguilles d’aragonite et silts) au niveau des pentes des Bahamas lorsque la plate-forme est ennoyée. Les derniers 4ka cal BP, le MIS 5e et le début du MIS 11 sont les principales périodes d’accumulation sédimentaire au cours des derniers cycles climatiques. L’érosion intra-pente, l’action des courants de fond et les processus de diagenèse précoce ont également été mis en évidence. La pente leeward se caractérise par une sédimentation très importante (wackestone) alors que la pente windward a conservés a morphologie pliocène avec localement des accumulations sédimentaires quaternaires de faible épaisseur (wackestone à packstone)This study proposes a reconstruction of the quaternary sedimentary history of two Bahamian slopes (leeward and windward). This work is based on the stratigraphicand sedimentary analysis of 34 marine cores recovered mainly from the CARAMBAR oceanographic cruse (2010). A high-resolution stratigraphic study was conducted by coupling several tools including ecostratigraphy based on planktonic foraminifera assemblages, which allowed dating all sedimentary sequences despite early diagenesis processes. The sedimentary analysis of the marine cores proposes a new classification for carbonate sediment. It characterizes the dominant particle distributions at the time of deposition and allows for discriminating the fine sediments and for determining the depositional processes such as off-bank transport, contouritic or gravity deposits, and slightly altered sediment. Off-bank transport is the mainprocess responsible for high-accumulation of platform carbonate ooze (aragonite needles and silt) on the Bahamian slopes. It predominates during major flooding of the platform, so during the last 4 ka cal BP, the MIS 5e and at the on set of the MIS11. Intra-slope erosion, bottom currents, and early marine diagenesis processes have also been highlighted. The leeward slope is characterized by a high accumulation of wackestone sediment where as the windward slope preserved its Pliocene morphology with local quaternary sediment accumulation (wackestone to packstone)

Full textAbstract:
The work undertaken in this study empirically explores the determinants of regulatory bank capital buffers, and how they influence bank decisions. Focusing on bank capital management under the Basel I framework, this thesis serves to address some of the concerns that have been voiced regarding the implementation of the new regulation (Basel II) and the broader economic effects that could result. In particular, the research chapters of this thesis examine the cyclical behavior of European bank capital buffers, the long run relationship between bank capital buffers and charter values, and the simultaneous adjustments of capital and risk. In each of the research chapters, we acknowledge the endogenous nature of the capital decision of a bank, and assume that banks will define an internally optimal probability of default (a function of risk and capital) to be managed over the long term. Adjustment costs, illiquid markets, together with the costs associated with a regulatory breach contribute as factors in a banks internal decision when setting a target capital ratio. Treating capital in this way, we note that it is the amount of capital held above the requirement that determines a banks attitude towards risk. Importantly, this work has shown that excessive risk taking is rarely a consequence of insufficient capital.

Full textAbstract:
The goal of this study was to investigate whether mathematics teachers in Brazil had implicit gender biases, and if that potential bias was related to students' confidence and interest. The literature shows that there is a significant gender gap in mathematics achievement favoring boys, and Brazil is a special case in that it has one of the largest divergences in the world. This study investigated whether mathematics teachers in Brazil had implicit gender biases, if that bias was related to their students' confidence and interest in mathematics, and in what ways teachers' bias could be observed in conversations about teaching.
For this study I surveyed 40 teachers, along with the students in one of each instructor’s mathematics classes. Teachers were asked to respond to a demographic questionnaire and implicit association test (IAT), while students were asked to respond to a questionnaire measuring their self-assessed confidence and interest in mathematics. At a later date, 10 teachers were selected to be interviewed, based on their IAT scores.
The results show that mathematics teachers in Brazil had implicit gender biases regarding mathematics, but that their respective biases varied significantly. Male teachers were significantly biased in favor of boys, while female teachers were not. Teachers' implicit biases also varied depending on their educational levels. Students' confidence and interest in mathematics were shown not to be related to their teacher's measure of bias. However, confidence and interest did vary based on whether students attended public or private schools – with private schools having a significantly larger gender gap in both of these factors, and students' grade -- with the gap being wider among older students. Students' interest in mathematics also proved to be related to teachers' educational level, but their confidence in mathematics was not.
Teachers in Brazil believe overall that girls and boys behave differently from each other in school; furthermore, they believe that these differences are due to societal and parental pressures and expectations regarding gender. Teachers who associated mathematics with boys did not appear to be aware of that implicit bias, and in conversation often referred to gender differences in a way that indicated they thought girls had advantages in school that boys did not.

When using filter bank to analyze signal, multiplication dominate most of computation complexity, it has an impact on dynamic power. In this thesis, instead of using linear convolution in time domain to analyze signal, we use circular convolution in frequency domain to implement filter bank. In this way, the computation complexity would be considerably reduced. However, it would not have obviously decreasing of the number of multiplication, if we using traditional fast fourier transform.。In this application, due to the input signal is real, we exploit real fast fourier transform(RFFT) to replace traditional fast fourier transform. We implement a 10.7-ms, 18-band, 1/3-octave quasi-ANSI filter bank in frequency domain. Comparing that with previous state-of-the-art design, the propose frequency domain quasi-ANSI filter bank saves approximately 54% computation complexity. Next, due to this system is in frequency domain, we could exactly know the region which are inside stopband of the filter. By only calculate the region which are inside stopband, we reduce more computation complexity successfully. For each output sample, it saves approximately 70% computation complexity。The proposed quasi-ANSI filter bank has been implemented in TSMC 90 nm CMOS high-VT technology and with gated-clock. The test chip can be operated at 13 MHz to real-time process 24 KHz audio and it consumes approximately 14 μW (@0.9V) dynamic power. Comparing with previous state-of-the-art design, this work saves approximately 77% of dynamic power.

Applying to a panel of 3,544 banks in 49 countries of the period 1996~2003. Our results shows that： 1. The response of bank lending tends to be stronger for banks with less capital ratios when facing adverse capital shocks. 2. Using the bank capital ratio as a measure of the country’s degree of information asymmetry, the effect of capital loss on bank lending tends to be greater for banks with less capital ratio. 3. Similarly, when using bank assets size ratio as a measure of the country’s degree of information asymmetry, the effect of capital loss on bank lending tends to be greater for small banks.

This paper examines the impact of bank competition on bank market value and explores the relationship between bank efficiency, bank competition, bank risk and bank market value in the European Union’s banking industry from 1997 to 2010. This paper uses the Lerner Index to measure bank competition and applies the fixed effects and GMM technique in the method of estimation and adopts the loan loss provision, Z-score, and idiosyncratic risk to measure bank risk . The main results show that (1) for financial information, bank book value is positively related to bank market value, and (2) for non-financial information, bank market competition is negatively related to bank market value, and (3) for bank risk, that the Z-score is positively related to bank market value, and the loan loss provision is negatively related to bank market value, and the idiosyncratic risk is negatively related to bank market value, and (4) for non-financial information, cost efficiency is positively related to bank market value when we use fixed effect model, and it shows that the explanatory power of the relationship between bank market value, financial information and non-financial information is substantially enhanced when we use fixed effect model.

Full textAbstract:
Micro-credit--small amounts of collateral-free institutional loans extended to jointly liable group members for self-employment--was first introduced by the Grameen Bank of Bangladesh in the mid 1970s. The "programmatic success" of the Bank-recruitment of clients, investment of loans, recovery rates on invested loans and profit margin-has internationalized micro-credit; it is now spread worldwide. There is a growing sense that micro-lending projects for women have potential to achieve the goal of equitable (women's entitlement to resources), and sustainable (independent stability and continuity) development. However, my dissertation, which is based on thirteen months of ethnographic field research on Grameen lending to women in a rural community of Bangladesh, challenges the conventional understanding of small-scale lending and the orthodox view of its success. The dissertation consists of an anthropological analysis of women borrower involvement with the credit program and implications of the lending structure for women borrowers, their household members, and bank workers. In theoretical terms women's involvement with micro-credit has been examined within the context of "normative entitlements" of patriarchy. The concepts of "public and hidden transcripts" (Scott 1990), and "practice theory" (Bourdieu 1977) are used to present the anomalies between ideology and practices of the lending institution and the informants. "Cultural hegemony" (Gramsci 1971) helps to analyse the reproduction of ideology of dominance and violence toward women in society, both unintended and organizational. The research findings suggest that women become the primary target of the micro-credit program because of their socio-cultural vulnerability, i.e., the requirements of regular attendance by borrowers in weekly meetings at the loan centre, and the rigid repayment schedule of loans. The program extends credit to women, but in the household women often "pass on" their loans to men, or men take control over women's loans, or loans are used to meet the emergency consumption needs of the household. In this system, women borrowers often lose control over their loans but bear the consequences of the debt burden in their households and loan centres. The research indicates a strong link between "programmatic success" of the Bank and current practices of credit extension to women. Debt-cycling among borrowers is a consequence, i.e., the need to pay off previous loans with new ones. Bank workers are expected to increase disbursement of loans among their clients and press for high recovery rates to earn the profit necessary for institutional economic viability. The bank workers and borrowing peer loan group members in centres press on clients for timely repayment, rather than working to raise collective consciousness and borrower empowerment as envisaged in the Bank's public transcript. Institutional debt burdens on individual households increases tension and anxiety among household members which in turn produces new forms of social and institutional dominance over many women borrowers of the project.

Optical amplifier is a key component for optical communication systems. Optical amplifiers amplify optical signals without any complex optical-electronic or electronic-optical transform and it has many benefits. Such as high gain, high output power, low noise, broadband, independent of the form of signal and the modulation frequency. In the past few years, according to the dramatic increase in information and the rapid developments of multimedia and network communication, the demand for transmission bandwidth grows with each passing day. The transmission band has extended from C-band (1530nm-1565nm) to L-band (1570nm-1610nm). So the amplifier has also extended the amplified band from conventional C-band to L-band. In this paper, the main topic is the design of gain enhancement and gain flatness for L-band EDFA. In which, we study the gain enhancement by 980nm-band pumping and C-band laser injection. For the gain flatness, we use two methods. First, we use a second pumping source, 980nm with 24mW, and 20m EDF. Then we obtain a high gain over 33dB and 1.87dB gain flatness. Second, we just add another 16m EDF without any pumping source after the first stage. Then we obtain a high gain over 31dB and 1.76dB gain flatness. The main feature of this paper is that we combine 980nm band pumping and C-band laser injection. Besides, we do not need too long erbium-doped fiber, too many pumping sources and do not need gain flatten filter to obtain the results of high gain (over 30dB) and a flatness gain spectrum (less than 2dB).

Internet banking indicates that banks can provide effective service through information technology, primarily using the internet to facilitate their services and overcome the barrieies caused by locations and working hours of the bank. Therefore, customers can complete the transactions instantly. In order to satisfy the needs from customers and to improve the quality of service, there is a tendency towards the cooperation between the information technology and banking services. One of the strategy popularly used in internet bank is to reduce the dependence on manpower, so that the saved efforts can be either used on clients with higher potentiality of expenditure or to used to create a win-win situation that both banks and clients can reduce the amount of costs and time. An questionnaire was used to evaluate the effect of our case study -TCB bank, Participants' career are work in bank, to probe into the relation between the customers used the E-BANK and bank’s employees a workload. Result shows that subjects believe in using the e-bank is worse to reduce the workload in apply for a loan, open new account, to register loss a passbook and ATM card application. On the other businesses is more benefit to reduce workload of bank’s employees. Moreover, we recommend that designer improving the e-bank serving interface and its procedure to simply and user-friendly in the future: The different background bank’s employees have quite different point of view in customer using e-bank to inquire about products information, transfer accounts and open new account. Hence, Banker should provide suitable marketing strategy and education training for customers. Those ways might increase customer’s acceptability and reliability, for the purpose of to reduce workload of bank’s employees.

With different requirements on the band allocations, this thesis proposes two methods for the design of quad-band bandpass filters. Thus the designed filters are fabricated on the printed circuited boards and verified by experiments. The first part focuses on the design for closely spaced pass-bands. Through a general idea of frequency transformation, the poles and zeros of a single band response are transformed into poles and zeros of a multiband response according to the cutoff frequency of each band. Then, theoretical analysis is made to predict the nth order response and discuss the distribution of the numbers of poles and zeros. Finally, to reduce the number of resonators, a method for extracting the resonant frequency points between multi-mode and single mode resonators is proposed. If the module about resonant frequency points is constructed, the band-pass response of multi-band could be directly realized by designing the fundamental single-band Chebyshev response and achieving the fast and low-cost circuit design. The second part deals with the case of arbitrarily spaced pass-bands. The design concept is to connect four pass-bands together to form quad-band response by exploiting the frequency orthogonality. Then, to avoid loading effect by tapped line, parallel coupled lines are served as the I/O coupling structure to meet external quality factors for quad-band requirements. Moreover, multi-mode resonators are introduced to replace with many single-mode resonators and utilize the concepts of coupling matrix to explain the location of mode-frequency. By this way, the number of resonators and circuit area can be reduced. Finally, we make improvement for stopband. The four circuits are fabricated in this thesis, and the simulated results show a good agreement with the measured results. About the first part, the open-loop and net-type resonators are applied. These two quadband filters are designed and fabricated with the areas 1.18λg × 0.144λg ,0.533λg × 0.27λg , the center frequencies at 1.86、1.95、2.04、2.14GHz, 1.82、1.94、2.06、2.18GHz, the fractional bandwidth 1.5%、1.33%、1.33%、1.5%, 2.2%、1.85%、1.75%、1.84%, and the insertion loss 2.2、2.3、1.8、1.3dB, 1.2、1.7、2、1.2dB, respectively. The second part is the combination of coupled lines and net-type resonators. The occupied area is 0.788λg × 0.066λg , the center frequencies at 0.8、1.0、1.4、1.8GHz, the fractional bandwidth about 12.1%、8.3%、5.5%、3.8%, and the insertion loss 1.6、2、2.5、2.7dB.
