A generalized rule-based short-term load forecasting technique
(Virginia Tech, 1991-12-05)
<p>A newly-developed technique for short-term load forecasting is generalized. The algorithm combines features from knowledge-based and statistical techniques. The technique is based on a generalized model for the weather-load ...
Estimation of nonlinear systems using Jump Matrix Technique
(Virginia Tech, 1988-07-05)
Representation and simulation of a high level language using VHDL
(Virginia Tech, 1994-12-05)
<p>This paper presents an approach for representing and simulating High Level Languages (HLL) using VHDL behavioral models. The graphical representation, a Data Flow Graph (DFG), is used as a base for the VHDL representation ...
Development of a Testbed for Evaluation of Electric Vehicle Drive Performance
(Virginia Tech, 1997-08-27)
This thesis develops and implements a testbed for the evaluation of inverter fed motor drives used in electric vehicles. The testbed consists of a computer-controlled dynamometer connected to power analysis and data ...
An artificial neural network approach to transformer fault diagnosis
(Virginia Tech, 1996)
A hybrid frequency modulated CDMA communication system
(Virginia Tech, 1996-07-05)
<p>The wireless communications industry has experienced tremendous growth worldwide in the past decade. Numerous cellular communication systems have been developed to meet this need. In North America, AMPS, IS-54, 1S-95 ...
Time domain antenna pattern measurements
(Virginia Tech, 1996)
Multipath on far-field antenna ranges causes distortion of antenna pattern measurements: The multi path components have differing path lengths and hence can be separated by illuminating the antenna under test with ...
A fuzzy logic solution for navigation of the Subsurface Explorer planetary exploration robot
(Virginia Tech, 1997-05-15)
<p>An unsupervised fuzzy logic navigation algorithm is designed and implemented in simulation for the Subsurface Explorer planetary exploration robot. The robot is intended for the subterranean exploration of Mars, and ...
Separation of the common-mode and the differential-mode conducted electromagnetic interference noise
(Virginia Tech, 1994-02-05)
One of the difficulties in solving E:MI problems is the lack of diagnostic tools available. In this thesis work, a tool, called Noise Separator, is developed, which can be used to decipher the differential-mode (DM) noise ...
Mach bands, Hermann grid, and lateral inhibition in the retina
(Virginia Tech, 1990-08-06)
<p>Literature about two illusions that are traditionally linked to lateral inhibitory processes in the retina is surveyed. Despite much research and a long history, the Mach bands illusion has not yet been very well-understood. ...
