Abstract:

Pulsed power flash radiography is a rapidly growing technology which involves the generation of intense and short bursts of electric pulses to generate high energy X-rays to inspect dense objects. The generation of fast transition, short width, repetitive pulses for effective output requires switching technology which has limitations. From the traditional slow switching gas trigger switches, switching technology has evolved to semiconductors which has led to improved switching characteristics and delivered pulse shapes. One such semiconductor which is of interest in flash radiography is a powe

Este trabalho apresenta o projeto de um amplificador de potência (PA) de rádio-frequência (RF) linear em tecnologia complementar metal-oxido silício (CMOS). Nele são analisados os desafios encontrados no projeto de PAs CMOS assim como soluções encontradas no estado-da-arte. Um destes desafios apresentados pela tecnologia é a baixa tensão de alimentação e passivos com alta perda, o que limita a potência de saída e a eficiência possível de ser atingida com métodos tradicionais de projeto de PA e suas redes de transformação de impedância.

Abstract:

Includes bibliographical references (leaves 78-80).<br>The main aims of this project were to develop and prototype a Point Coupled Linear Transformer (PCLT) displacement sensor, and to perform a general exploration of the PCLT technology. The PCLT is a recent invention that has planar PCB windings and a non-contacting movable core, and relies on variable induction to detect displacement. Different core materials and shapes are investigated. The transformer windings layout is optimized for symmetrical response and high primary to secondary voltage coupling.

Abstract:

Due to the increase in electrical demand and renewable penetration, electrical utilities need to improve and optimize the grid infrastructure. Fundamental components in this grid infrastructure are transformers, which are designed conservatively on the base of a static rated power. However, load and weather change continuously and hence, transformers are not used in the most efficient way. For this reason a new technology has been developed: Dynamic transformer rating (DTR). By applying DTR, it is possible to load transformers above the nameplate rating without affecting their life time expect

Abstract:

The Linear Voltage Differential Transformer (LVDT) is an accurate sensor for stem diameter measurements. Based on the results of this dissertation it was found that stem diameter [mm] was related to water content [grams] of the cotton crop by the following equation: W(D) = 0.114(D)³ˑ¹⁸² Also the ratio of stem diameter contraction rate to the rate of water loss in cotton was experimentally determined to be: (dW/dt)/(dD/dt) = (0.166 [g min⁻¹])/(0.535 [μm min⁻¹]) = (.0469% per minute)/(.0039% per minute). Similarly the cellular water potential was derived to be a non linear function of stem diame

The Monte Carlo method will be described and scrutinised, with the quasi-Monte Carlo method being favoured for large problems. An example will illustrate how the choice of Monte Carlo method will affect the efficiency of the simulation when evaluating functions of different dimensions. Then an overview of mathematical optimization is given, from its simplest form to nonlinear, nonconvex

Abstract:

Families of linear functionals on a vector space that are mapped to each other by a group of symmetries of the space have a significant amount of structure. This results in computational redundancies which can be used to make computing the entire family of functionals at once more efficient than applying each in turn. This thesis explores asymptotic complexity results for a few such families: contingency tables and unranked choice data. These are used to explore the framework of Radon transform diagrams, which promise to allow general theorems about linear summary statistics to be stated and p

Abstract:

Arbuscular mycorrhizal (AM) fungi are key soil symbiotic microorganisms, intensively studied for their roles in improving plant fitness and their ubiquity in terrestrial ecosystems. Research on AM fungi is difficult because their obligate biotrophic nature makes it impossible to culture them in the absence of a host. Over the last three decades, Ri T-DNA transformed roots have been the gold standard to study AM fungi under in vitro conditions. However, only two host plant species (Daucus carota and Cichorium intybus) have been routinely used to in vitro propagate less than 5% of the known AM f

Abstract:

We propose an efficient iterative data interpolation method using continuity along reflectors in seismic images via curvelet and discrete cosine transforms. The curvelet transform is a new multiscale transform that provides sparse representations for images that comprise smooth objects separated by piece-wise smooth discontinuities (e.g. seismic images). The advantage of using curvelets is that these frames are sparse for high-frequency caustic-free solutions of the wave-equation. Since we are dealing with less than ideal data (e.g. bandwidth-limited), we compliment the curvelet frames with th

Abstract:

Predictive multiple suppression methods consist of two main steps: a prediction step, in which multiples are predicted from the seismic data, and a subtraction step, in which the predicted multiples are matched with the true multiples in the data. The last step appears crucial in practice: an incorrect adaptive subtraction method will cause multiples to be sub-optimally subtracted or primaries being distorted, or both. Therefore, we propose a new domain for separation of primaries and multiples via the Curvelet transform. This transform maps the data into almost orthogonal localized events wit

Since, the structure and parameters of discrete-time models are difficult to relate to the underlying continuous-time system of interest it is necessary to compute the continuous-time equivalent from the discrete-time model.

Abstract:

Thesis (S.M. and S.B.)--Massachusetts Institute of Technology, Dept. of Nuclear Science and Engineering, 2012.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 104-106).<br>Patient positioning is crucial to accurate dose delivery during radiation therapy to ensure the proper localization of dose to the target tumor volume. In patient positioning for stereotactic radiation therapy treatment, classical image registration methods are computationally costly and imprecise. We developed an automatic, fast, and robust 2D-3D registration method to improve accuracy an

Abstract:

In cryptography, periodic sequences with terms in F2 are used almost everywhere. These sequences should have large linear complexity to be cryptographically strong. In fact, the linear complexity of a sequence should be close to its period. In this thesis, we study the expected value for N-periodic sequences with terms in the finite field Fq. This study is entirely devoted to W. Meidl and Harald Niederreiter&rsquo<br>s paper which is &ldquo<br>On the Expected Value of the Linear Complexity and the k-Error Linear Complexity of Periodic Sequences&rdquo<br>We only expand this paper, there is no i

Abstract:

Le domaine de la chimie bioanalytique est en plein développement. Les tendances vers une caractérisation plus précise, une analyse à haut débit et une automatisation accrue offrent la promesse de systèmes capables de fournir des informations plus détaillées sur les systèmes biologiques vivants. Les biofilms sont répandus dans la plupart des écosystèmes. Ils peuvent être formés par la plupart des microorganismes. Les biofilms microbiens sont des communautés multicellulaires de bactéries, adhérant à une surface, entourées d'une substance polymère extracellulaire (EPM). En raison de leur origine
