Cascading Events in the Aftermath of a Targeted Physical Attack on the Power Grid
(Virginia Tech, 2019-03-29)
This work studies the consequences of a human-initiated targeted attack on the electric power system by simulating the detonation of a bomb at one or more substations in and around Washington DC. An AC power flow based ...
Insulated gate transistors: characteristics and application to motor control
(Virginia Polytechnic Institute and State University, 1984)
Ionospheric Scintillation Prediction, Modeling, and Observation Techniques for the August 2017 Solar Eclipse
(Virginia Tech, 2017-08-16)
A full solar eclipse is going to be visible from a range of states in the contiguous United States on August 21, 2017. Since the atmosphere of the Earth is charged by the sun, the blocking of the sunlight by the moon may ...

A Comparative study of RISC vs. CISC philosophies of implementing mathematical functions
(Virginia Tech, 1989-12-05)
<p>A comparative study of the RISC philosophy of implementing mathematical functions vs the CISC. philosophy implementing the same functions is undertaken. This study tries to verify whether, the RISC philosophy is suited ...
Fiber-Optic Michelson Interferometer with Faraday Mirrors for Acoustic Sensing using a 3 x 3 Coupler and Symmetric Demodulation Scheme
(Virginia Tech, 2016-11-02)
For the past 40 years, acoustic sensing has been a major avenue for the growth of interfero- metric fiber-optic sensors. Fiber-optic acoustic sensors have found uses in military, commer- cial, and medical applications. An ...
Spectrum Management in Dynamic Spectrum Access: A Deep Reinforcement Learning Approach
(Virginia Tech, 2019)
Dynamic spectrum access (DSA) is a promising technology to mitigate spectrum shortage and improve spectrum utilization. However, DSA users have to face two fundamental issues, interference coordination between DSA users ...
Design of a video measurement system
(Virginia Polytechnic Institute and State University, 1988)
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 ...
