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 ...
Detection of Coreferences in Automatic Specifications Analysis
(Virginia Tech, 1994-01-04)
Specifications on digital hardware systems typically contain descriptions and requirements expressed in natural language and diagrams of various types. The objective of the research reported here is the automatic detection ...
Analysis of Path Loss from a Transmitter in an Aircraft Cabin to an Exterior Fuselage-Mounted Antenna
(Virginia Tech, 2007-12-04)
It is important to investigate the threat posed to commercial aircraft by on board electronic
transmitters in the passenger cabin and the cargo holds of large transport aircraft. These
transmitters may be in the form of ...
Nonlinear Deadbeat Current Control of a Switched Reluctance Motor
(Virginia Tech, 2009-12-04)
High performance current control is critical to the success of the switched reluctance motor (SRM). Yet high motor phase nonlinearities in the SRM place extra burden on the current controller, rendering it the weakest link ...
Wide Area Analysis and Application in Power System
(Virginia Tech, 2009-12-07)
Frequency monitoring network (FNET) is an Internet based GPS synchronized wide-area frequency monitoring network deployed at distribution level. At first part of this thesis, FNET structure and characteristics are introduced. ...
Design of a PC based Data Acquistion System for a Switched Reluctance Motor
(Virginia Tech, 1988-12-05)
The Switched Reluctance Motors(SRM) have gained considerable attention in the
variable speed drive market mainly due to the simple construction of the motor and
the possibility of developing low cost converters and ...
Self-Calibrated Interferometric/Intensity Based Fiber Optic Temperature Sensors
(Virginia Tech, 2000-12-12)
To fulfill the objective of providing robust and reliable fiber optic temperature sensors capable of operating in harsh environments, a novel type of fiber optic sensor system titled self-calibrated interferometric/intensity-based ...
Developing an Automated Explosives Detection Prototype Based on the AS&E 101ZZ System
(Virginia Tech, 1997-09-22)
This thesis describes the development of a multi-sensor, multi-energy x-ray
prototype for automated explosives detection. The system is based on the American
Science and Engineering model 101ZZ x-ray system. The 101ZZ unit ...
Adaptive Antenna Arrays Applied to Position Location
(Virginia Tech, 1997-08-04)
Wireless communication has enjoyed explosive growth over the past decade. As demands for increased capacity and quality grow, improved methods for harnessing the multipath wireless channel must be developed. The use of ...
Applications of Multiwavelets to Image Compression
(Virginia Tech, 1999-06-08)
