Electrical Breakdown Studies of Partial Pressure Argon Under KHz Range Pulse Voltages
(2010-01-12)
Electronics operating in a partial vacuum may experience a gaseous breakdown when strong electric fields are present. The breakdown voltage for a gas decreases as the pressure decreases from atmospheric conditions and ...
Identification of Individual Contributions to Total Flicker Levels in Electric Power Systems
(2010-04-02)
Total flicker levels in an electric power system can be contributed to from multiple sources of flicker. Methodologies for allocating portions of this total flicker level to the responsible loads are studied. The representation ...
RF Design and Analysis of a Novel Elliptical Reduced Surface Wave Antenna for Wireless Applications
(2010-04-02)
The Reduced Surface Wave (RSW) antenna is a relatively new class of microstrip patch
antenna. An RSW antenna has the ability to drastically reduce both surface and lateral wave
radiation, which leads to an increase in ...
Design and Implementation of High-Speed Low-Power Analog-to-Digital and Digital-to-Analog Converters
(2010-04-28)
With the rapid development of modern communication and personal wireless products, there are increased demands for next generation communication transceivers that feature ultra-high data conversion rates with reconfigurable ...
Cold Cathode Materials for Pseudospark Switches
(2010-04-14)
In general, for plasma switches, the initiation of the plasma is critical and this is usually achieved by a “trigger” scheme. The seed electrons needed to initiate a breakdown can be generated by several means such as ...
High Temperature Electronics Packaging Processes and Materials Development
(2010-08-16)
Silicon carbide device technology is being developed for power electronics applications for use at high temperatures. In recent studies, SiC based electronics and sensors have also been demonstrated for extended operation ...
4D Strain from Tagged Magnetic Resonance Images by Unwrapping the Harmonic Phase Images
(2010-12-14)
Accurate assessment of ventricular function is clinically important. Tagged magnetic resonance imaging (MRI) is the modality of choice for calculating parameters such as torsion, rotation and strain that characterize ...
Current Sensing Completion Detection for High Speed and Area Efficient Arithmetic
(2010-12-17)
Adders and multipliers are the most widely used computational units in integrated circuits. In many compact low power and high speed designs, more complex arithmetic operations such as multiplication are performed through ...
Lane Level Localization with Camera and Inertial Measurement Unit using an Extended Kalman Filter
(2010-12-07)
This thesis studies a technique for combining vision and inertial measurement unit (IMU) data to increase the reliability of lane departure warning systems. In this technique, 2nd-order polynomials are used to model the ...
Energy Source Lifetime Optimization for a Digital System through Power Management
(2010-11-16)
This work analyzes a typical battery powered digital electronic system and we propose a system level voltage scaling method and a functional power management method called instruction slowdown for low power. In the first ...
