Diffraction by Building Corners at 28 Ghz: Measurements and Modeling
(Virginia Tech, 1998-06-03)
This thesis presents the results of a 28 GHz continuous-wave (CW) diffraction measurement campaign in the Washington, DC area. It describes the measurement approach including information on equipment and testing methods. ...
Intelligent Parameter Adaptation for Chemical Processes
(Virginia Tech, 1999-07-08)
Reducing the operating costs of chemical processes is very beneficial in decreasing a company's bottom line numbers. Since chemical processes are usually run in steady-state for long periods of time, saving a few dollars ...
EMI Characterization and Improvement of Bi-Directional DC/DC Converters
(Virginia Tech, 1999-09-14)
A worldwide awareness of the environment is accelerating fuel cell vehicle development. With respect to power electronics, special requirement is on the development of high efficiency, high voltage ratio bi-directional ...
Design and analysis of shipboard electrical distribution
(Virginia Tech, 1990)
This research is a preliminary design and feasibility analysis of a new type of shipboard electrical distribution system for Naval vessels. The design combines three traditionally separate disciplines: damage control, ...
A machine vision system for classifying rectangular cabinet frames
(Virginia Tech, 1994-08-18)
This thesis describes a machine vision solution to an industrial classification task. The specific problem is the identification of kitchen cabinet frames that travel on a conveyor belt. For these components, it is possible ...
Variable Bus Voltage Modeling for Series Hybrid Electric Vehicle Simulation
(Virginia Tech, 1997-12-01)
A growing dependence on foreign oil, along with a heightened concern over the environmental impact of personal transportation, had led the U. S. government to investigate and sponsor research into advanced transportation ...
The operating characteristics of a synchronous motor and their relation to stability
(Virginia Tech, 1939-06-05)
In review, the author is struck with a feeling of the relative insignificance of his findings. Other sources of information seem to have a wealth of ideas, a scope far beyond the present investigation, and a variety of ...
Medium access delay evaluation for distributed queueing dual bus (DQDB) MAC protocol
(Virginia Tech, 1992)
Application of the photodiode in design and implementation of a 2-D position detector
(Virginia Tech, 1994-05-04)
Flowgrapher: generation of conceptual graphs from flowcharts
(Virginia Tech, 1994)
