Multiscale Modeling of Defect Generation and Diffusion in Semiconductor Materials
(2013-02-25)As semiconductor device technology continues to evolve, great challenges arise in many areas. With the continuous shrinkage of the design window, a better understanding of the detailed physical processes that occur during ... -
Multiscale Simulation of Phase Change Memory
(2014-02-24)This PhD thesis investigates the phase change material (PCM) based memory technology using multiscale theoretical modeling and numerical simulation. The multiscale analysis consists of three hierarchical parts: (i) the ... -
Neural network based shaped neighborhoods: a design retrieval system
(1999)The life cycle cost of a single detail part in a large assembly such as an airframe includes design, tooling, manufacture, maintenance and other associated computing overhead throughout the 40 year life of the part. These ... -
A New Landmark-Independent Tool for Quantifying and Characterizing Morphologic Variation
As advances in multi-dimensional imaging are made, there is a growing need for tools that enable quantitative assessment of both embryonic and postnatal structure and form. To this end, this dissertation develops a ... -

New Methods of Complex Matrix Factorization for Single-Channel Source Separation and Analysis
(2013-04-17)Throughout the day, people are constantly bombarded by a variety of sounds. Humans with normal hearing are able to easily and automatically cut through the noise to focus on the sources of interest, a phenomenon known as ... -
New techniques for streaming MPEG video over the internet
(2003)Many video coding standards have been established for various streaming video applications, such as H.263 for low-bit-rate two-way video communications, MPEG-2 for broadcasting and general high-quality video applications, ... -
Noninvasive temperature estimation technique for HIFU therapy monitoring using backscattered ultrasound
(2005)High Intensity Focused Ultrasound (HIFU) has potential applications in a variety of medical fields that benefit from selective destruction of tissue volumes. Being a noninvasive technique, HIFU provides the ability to ... -
Numerical simulations of interactions of electromagnetic waves with lossy dielectric surfaces using fast computational methods
(2000)The scattering of electromagnetic waves by lossy dielectric random rough surfaces with large permittivity has broad applications in natural media. Because many of natural medium are lossy and with surface roughness. In the ... -
An Object-Oriented Parallel Social Simulation Framework
Agent-Based Modeling (ABM) is a powerful social simulation technique that employs a bottom-up approach for opinion dynamics study. In this work, we develop a social simulation framework based on ABM. The framework supporting ... -
Offset Pipelining for Coarse Grain Reconfigurable Arrays
This dissertation presents an execution model and compilation algorithms to advance the utility of coarse-grained reconfigurable arrays (CGRAs). These time multiplexed, spatial architectures can provide improved energy ... -
Operations and Planning in Sustainable Power Systems
Renewable generation, e.g., wind power and photovoltaic resources, and non-traditional energy providers, e.g, flexible loads and energy storage, have demonstrated their potential to eliminate or, at least, to alleviate ... -
Optical Limiter Based on Phase Change Material
Optical limiter is a potential optical device to limit input light intensity to protect optical sensitive devices. It has a large transmissivity (T) when the input intensity is low and a low transmissivity when the input ... -
Optical multisensors based on surface plasmon resonance
(2000)Biosensors based on surface plasmon resonance (SPR) detect biological substances through changes in the refractive index (RI) at the sensor surface. We present two optical multisensors designed to improve the robustness ... -
Optics-Based Quantum Information and Sensing Platforms Utilizing the Nitrogen-Vacancy Center in Diamond
The nitrogen-vacancy (NV) center is a point defect in the diamond crystal lattice, forming a localized-electron system with unique optical and spin properties. In particular, optical control and read-out of the spin state, ... -
Optimal Scheduling of a Natural Gas Processing Facility with Real-time Price Demand Response
Demand Response (DR) has been a hot topic since the introduction of the smart grid concept. The USA, Canada, and some European countries are researching the benefits of DR programs and their integration methodology into ... -
Optimizable Design Schemes in Communication Systems for Providing Anonymity and Confidentiality
In applications requiring anonymity such as electronic mail, evading website censorship, and file sharing, the identities of source-destination pairs for each data flow should be untraceable. To achieve this goal, anonymous ... -
Optimized Decoding for Auditory Attention Detection
The method of stimulus reconstruction has shown to be an effective tool for detecting a listener's attentional focus in a multi-talker environment. Using electroencephalography (EEG), this technique aims to learn neural ... -
Organ volume estimation from magnetic sensor based 3D ultrasound data: application in gastric emptying
(1997)The study of gastric emptying requires measuring the change of stomach volume with time after a meal. A series of cross-sectional images of the stomach were acquired with conventional ultrasound imaging. The position and ...
