The application of thyristors to induction motor drive systems.
(Virginia Tech, 1967-05-22)
<p>This thesis provides a comparison of three different power circuit arrangements of thyristors for controlling the speed of an induction motor through control of the stator voltage. The output voltage harmonic structure ...
GNSS Hardware-In-The-Loop Formation and Tracking Control

Formation and tracking control are critical for of today's vehicle applications in and this will be true for future vehicle technologies as well. Although the general function of these controls is for data collection and ...
An implementation of an AMPS digital base station with adaptive Automatic Gain Control
(Virginia Tech, 1996-05-17)
<p>We consider the problem of designing a wide-band digital receiver for an Advanced Mobile Phone Service (AMPS) cellular system, and the associated problem of choosing an appropriate Analog-to-Digital (ADC) converter. The ...
Design of optical characteristics of ceria nanoparticles for applications including gas sensing and up-conversion
(Virginia Tech, 2012-12-13)
This thesis investigates the impact of doping on the optical and structural characteristics of cerium oxide (ceria) nanoparticles synthesized using chemical precipitation. The dopants selected are samarium and neodymium, ...

Development of experiments for the digital signal processing teaching laboratory
(Virginia Tech, 1988-07-05)
Digital Signal Processing (DSP) is a technology-driven field which develops as early as mid-1960 when computers and other digital circuitry became fast enough to process large amounts of data efficiently. Since then ...
Designing and Fabricating MEMS Cantilever Switches
(Virginia Tech, 2016-09-23)
In this thesis, MEMS switches actuated using electrostatic actuation is explored. MEMS switches that are lateral switches and clamped-clamped switches are designed, fabricated, and tested in this thesis. This thesis ...
Switching mode power supply noise source impedance measurement and EMI filter characterization
