Extraction Of Frequency-Dependent Electrical Characteristics Of Biological Tissues Using Ultra-Wideband Electromagnetic Pulse, Michael D. Seymour Jan 2004

Extraction Of Frequency-Dependent Electrical Characteristics Of Biological Tissues Using Ultra-Wideband Electromagnetic Pulse, Michael D. Seymour

Theses

There have been many important contributions to imaging for biomedical applications. The most popular methods include X-ray mammography, magnetic resonance imaging (MRI), ultrasound, and most recently, microwave imaging. While the first three of these have been used for biomedical applications for over three decades, microwave imaging has seen many developments over the last few years. This is primarily due to the large contrast in electrical parameters between different body tissues (including differences between healthy and diseased tissues) at microwave frequencies. There are also vast improvements possible for the comfort of the patient undergoing such imaging as compared to mammography. However, …

Embedded Charge For Microswitch Applications, Joanna Kiljan Jan 2004

Embedded Charge For Microswitch Applications, Joanna Kiljan

Theses

In this work a micro-electro-mechanical system (MEMS) is proposed for radio frequency (RF) switching applications. MEMS devices outperform the traditionally used solid-state devices in areas such as isolation, insertion loss, and linearity. However, micro switches suffer from high actuation voltage, lifetime limitations, and high packaging cost. A novel micro switch design that incorporates embedded charge in a cantilever structure can, in principle, enable low-voltage operation. This was the primary motivation for this study

Multiprocessor Dsp Implementation Of The Jpeg 2000 Codec, Scott Mayne

Theses

The transition to JPEG2000 from other image formats such as standard JPEG offers im proved compression and image quality, yet has not been widely adopted in practice. This is mainly due to the complexity of the JPEG2000 algorithm. Standard JPEG uses the Discrete Cosine Transform (DCT) and Huffmann encoding to achieve its compression, whereas JPEG2000 uses the wavelet transform and arithmetic encoding. Due to the wide acceptance of JPEG, there are processors such as Equator Technology's BSP-15 digital signal processor (DSP) that have been designed with features specifically for JPEG appli cations.

Generalized Analytical Model For Rf Planar Inductors Using A Segmentation Technique, Marie Yvanoff Jan 2004

Generalized Analytical Model For Rf Planar Inductors Using A Segmentation Technique, Marie Yvanoff

Theses

The planar coil inductor has become a very critical circuit component in RF mixed signal application where it can reside either on the package or in the chip. However, there is no clear methodology to accurately analyze the behavior of the inductor over a broad range of frequencies and for obtaining a particular physical layout for a required value of inductance. At present, it has been done by full wave solvers, approximate quasistatic analysis, and lumped element equivalent circuits, each with its own advantages and limitations. This work presents an analytical model based on a segmentation method in conjunction with …

P-Hip: A Multiresolution Halftoning Algorithm For Progressive Display, Mithun Mukherjee Jan 2004

P-Hip: A Multiresolution Halftoning Algorithm For Progressive Display, Mithun Mukherjee

Theses

This thesis describes and implements an algorithmic framework for memory efficient, 'on-the-fly' halftoning in a progressive transmission environment. Instead of a conventional approach which repeatedly reconstructs the continuous tone image from memory and subsequently halftones it for display, the proposed method achieves significant memory efficiency by storing only the halftoned image and updating it in response to additional information received through progressive transmission. Thus the method requires only a single frame-buffer of bits for storage of the displayed binary image and no additional storage is required for the contone data. The additional image data received through progressive transmission is accommodated …
