Knowledge-based and statistical load forecast model development and analysis
(Virginia Polytechnic Institute and State University, 1989)
ILoViT: Indoor Localization via Vibration Tracking
(Virginia Tech, 2018-04-23)
Indoor localization remains an open problem in geolocation research, and once this is solved the localization enables counting and tracking of building occupants. This information is vital in an emergency, enables ...
Fault simulation and test pattern generation for synchronous and asynchronous sequential circuits
(Virginia Tech, 1993-12-05)
In this dissertation, we propose two fault simulators, called HOPE and HOPE2, and an autolllatic test pattern generator (ATPG), called ATHENA, for synchronous and asynchronous sequential circuits. HOPE is a parallel fault ...
Interframe image coding with three-dimensional gradient motion estimation
(Virginia Tech, 1990-11-05)
Two new methods for coding image sequences in video conferencing systems are developed in this dissertation. A simple 3-D gradient operator is developed to estimate motion in an image sequence on a pixel-by-pixel basis. A ...
An Isolated Micro-Converter for Next-Generation Photovoltaic Infrastructure
(Virginia Tech, 2013-04-19)
Photovoltaic (PV) systems are a rapidly growing segment in the renewable energy industry. Though they have humble origins and an uncertain future, the commercial viability of PV has significantly increased, especially in ...
A study of the effects of linear networks on FM waves
(Virginia Tech, 1966-05-05)
Two methods of predicting the distortion which is generated in frequency-modulated waves during passage through linear networks have been investigated in this paper. The major emphasis has been placed on the Fourier method ...
A Power Conditioning System for Superconductive Magnetic Energy Storage based on Multi-Level Voltage Source Converter
(Virginia Tech, 1999-07-06)
A new power conditioning system (PCS) for superconductive magnetic energy storage (SMES) is developed and its prototype test system is built and tested. The PCS uses IGBTs for high-speed PWM operation and has a multi-level ...
Computational Modeling for Differential Analysis of RNA-seq and Methylation data
(Virginia Tech, 2016-08-16)
Computational systems biology is an inter-disciplinary field that aims to develop computational approaches for a system-level understanding of biological systems. Advances in high-throughput biotechnology offer broad scope ...
Facilitating FPGA Reconfiguration through Low-level Manipulation
(Virginia Tech, 2014-03-24)
The process of FPGA reconfiguration is to recompile a design and then update the FPGA configuration correspondingly. Traditionally, FPGA design compilation follows the way how hardware is compiled for achieving high ...
Zero-voltage switched resonant and PWM converters: design-oriented analysis and performance evaluation
(Virginia Tech, 1994-04-26)
The relative performance evaluation of the different alternatives of bridge topologies with zero-voltage switching is presented. A design-oriented analysis is developed to optimize implementation of the converters in terms ...
