(Virginia Tech, 1993)
Analysis and Design of a DCM SEPIC PFC with Adjustable Output Voltage
(Virginia Tech, 2015-03-31)
Power Factor Correction rectifiers are widely adopted as the first stage in most grid-tied power conversion systems. Among all PFC converts for single phase system, Boost PFC is the most popular one due to simplicity of ...
Reduced order power system models for transient stability studies
(Virginia Tech, 1993-12-05)
<p>As the load on the power system grows and new transmission facilities become increasingly difficult to build, the utilities must look to ways to make the most of the current transmission system. Adaptive relaying is one ...
Sapphire optical fiber sensors
(Virginia Tech, 1991-05-05)
<p>Fiber optic sensors offer many advantages over conventional sensors, including; small size, low weight, high strength and durability. Standard silica optical fibers are limited by the material properties of silica. ...

Applications of Non-linearities in RF MEMS Switches and Resonators
(Virginia Tech, 2015-04-06)
The 21st century is emerging into an era of wireless ubiquity. To support this trend, the RF (Radio Frequency) front end must be capable of processing a range of wireless signals (cellular phone, data connectivity, broadcast ...
Digital signal processing analysis of switched capacitor filters
(Virginia Polytechnic Institute and State University, 1982)
The effect of segment averaging on the quality of the Burg spectral estimator
(Virginia Polytechnic Institute and State University, 1984)
Simulation of multistage detector for spread-spectrum applications
(Virginia Tech, 1993-06-14)
The conventional single-user correlation receiver is not optimized for use with a multiple-access channel shared by users transmitting asynchronously independent data streams by modulating a set of assigned signal waveforms ...
