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 ...
Characterization of Optical Coupling and Back-reflection of Few Mode Fibers
(Virginia Tech, 2015-09-01)
The continued growth of the communications industry has caused interest in mode-division multiplexing (MDM) techniques to flourish in recent years. These techniques allow individual waveguide modes to be used as distinct ...
The operating charachteristics [sic] of a synchronous motor and their relation to stability
(Virginia Tech, 1939-06-05)
<p>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 ...
Spatio-Temporal Correlation in the Performance of Cache-Enabled Cellular Networks
(Virginia Tech, 2016-07-19)
Exact characterization and performance analysis of wireless networks should incorporate dependencies or correlations in space and time, i.e., study how the network performance varies spatially and temporally while having ...
A High Temperature Wideband Low Noise Amplifier
(Virginia Tech, 2016-01-27)
As the oil industry continues to drill deeper to reach new wells, electronics are being required to operate at extreme pressures and temperatures. Coupled with substantial real-time data targets, the need for robust high ...
Corrosion detection using metal coatings on fiber optic sensors
(Virginia Polytechnic Institute and State University, 1995)
Wideband electromagnetic characterization of Portland cement concrete
(Virginia Tech, 1995)
A comparison and study of the Born and Rytov expansions
(Virginia Tech, 1993-08-19)
Since the introduction of the Born and Rytov approximations for use in random wave propagation some forty years ago, a controversy has boiled over the regions of validity and relative merits of the methods. Although ...
Optimization of surface preparation technique for unipolar silicon direct bonding
(Virginia Tech, 1993-12-05)
<p>A special wafer bonding method called the Silicon Direct Bonding technique is used to study the bonding of unipolar (n-type, <100> oriented) silicon wafers. The primary objective of this thesis project is to find an ...
Rapid development of VHDL behavioral models
(Virginia Tech, 1992)
