Abstract:

Esta dissertação descreve o movimento quântico de uma partícula numa barreira de potencial parabólica, condicionalmente este sistema é chamado de oscilador invertido. Determinamos estados quânticos semiclássicos como família de estados coerentes generalizados (ECG), sendo construídos através da adaptação do trabalho de Malkin e Man´ko, determinando-se um operador que seja integral do movimento, parametrizado por algumas constantes e reconhecido como operador de aniquilação, cujos auto-estados tem características dos estados comprimidos. Discutimos suas propriedades e observamos q

Abstract:

Nanoscale p-channel transistors under negative gate bias at an elevated temperature show threshold voltage degradation after a short period of stress time. In addition, nanoscale (45 nm) n-channel transistors using high-k (HfO2) dielectrics to reduce gate leakage power for advanced microprocessors exhibit fast transient charge trapping effect leading to threshold voltage instability and mobility reduction. A simulation methodology to quantify the circuit level degradation subjected to negative bias temperature instability (NBTI) and fast transient charge trapping effect has been developed in t

Abstract:

High-quality factor oscillators are often used in measurements of verysmall force since they exhibit an enhanced sensitivity in the narrow frequencyband around resonance. Forces containing frequencies outside this frequencyband are often not detectable and the total force acting on the oscillatorremains unknown. In this thesis we present methods to eciently use theavailable bandwidth around resonance to reconstruct the force from partialspectral information.We apply the methods to dynamic atomic force microscopy (AFM) wherea tip at the end of a small micro-cantilever oscillates close to a samp

Abstract:

Ce travail de thèse est consacré à l'étude des propriétés radiatives d'isolants fibreux formés de fibres de silice. La détermination de ces propriétés est essentielle en vue de la modélisation du transfert thermique. Deux approches sont utilisées pour caractériser les milieux. Une première approche est une méthode basée sur l'étude de l'interaction rayonnement matière via la théorie de MIE. Le modèle obtenu ne dépend alors que de paramètres optiques (indices de la silice) et morphologiques (diamètre et orientation des fibres, masse volumique de l'isolant).

Nous étudions d'abord l'influence du mode annulaire Sud (SAM) sur la circulation méridienne de retournement Atlantique (AMOC) dans une simulation de contrôle avec IPSLCM4. Une phase positive du SAM, correspondant à une intensification des vents d'Ouest soufflant au Sud de 45° S, entraîne après 8 ans une accélération de l'AMOC, via une téléconnection atmosphérique peu réaliste. Une accélération de l'AMOC suit de 70 ans une phase positive du SAM, due à la propagation d'anomalies de sel du Sud vers le Nord de l'Atlantique. Ensuite, nous étudions dans quelle mesure l'Oscillation Multidécennale Atl

Abstract:

Impedance measurement as a function of frequency is being increasingly used for the detection of organic molecules. The main building block required for this is a sinusoidal oscillator whose frequency can be varied in the range of a few KHz to tens of MHz. The thesis describes the design of Integrated CMOS Oscillator Circuits. There are 2 designs presented in the thesis, one of which is based on the Wien Bridge and the other, on an LC architecture. They provide both in-phase and quadrature outputs needed for the determination of the real and imaginary parts of complex impedances. The inductor

Abstract:

Poorly damped oscillations that occur between the generators in large interconnected power systems often limit the amount of power that can be transmitted through a transmission corridor and are a threat to secure system operation. Coordinated insertion and removal of capacitors in series with a transmission line is one of the approaches that has been known for many years to be capable of enhancing the damping of power system oscillations. Unfortunately however, this approach historically relied on the operation of mechanical circuit breakers which were too slow and unreliable for the high-spe

Abstract:

The evolution of receiver architectures, built in modern CMOS technologies, allows the design of high efficient receivers. A key block in modern receivers is the oscillator. The main objective of this thesis is to design a very low power and low area 8-Phase Ring Oscillator for biomedical applications (ISM and WMTS bands). Oscillators with multiphase outputs and variable duty cycles are required. In this thesis we are focused in 12.5% and 50% duty-cycles approaches. The proposed circuit uses eight inverters in a ring structure, in order to generate the output duty cycle of 50%. The duty cycle

Abstract:

Amorphous oxide semiconductor (AOS) thin-film transistors (TFTs) constitute the central theme of this thesis. Within this theme, three primary areas of focus are pursued. The first focus is the realization of a transparent three-stage ring oscillator with buffered output and an output frequency in the megahertz range. This leads to the possibility of transparent radio frequency applications, such as transparent RFID tags. At the time of its fabrication, this ring oscillator was the fastest oxide electronics ring oscillator reported, with an output frequency of 2.16 MHz, and a time delay per s

For an induction motor drive actuated by an inverter, the power transistor exhibits inherent problem during its turn-on or turn-off. It is of essence to insert a time delay circuit to prevent a short circuit in the dc link. However, it causes the voltage distortion and gives rise to the dead-time effect. The torq

Abstract:

A main thrust of this thesis is to develop and explore linearization-based numeric-analytic integration techniques in the context of stochastically driven nonlinear oscillators of relevance in structural dynamics. Unfortunately, unlike the case of deterministic oscillators, available numerical or numeric-analytic integration schemes for stochastically driven oscillators, often modelled through stochastic differential equations (SDE-s), have significantly poorer numerical accuracy. These schemes are generally derived through stochastic Taylor expansions and the limited accuracy results from dif
