Lattice-Reduction Aided Linear Equalization For Wireless Communications Over Fading Channels
(2008-09-09)
Modern wireless communications ask for high data rate, high transmission performance and low complexity. High data rate induces frequency-selective channels because of the relatively shorter symbol duration than the delay ...
Particle Swarm Optimization Applied to the Design of a Nonlinear Control
(2008-09-09)
A method of searching for a tuning of an input to state linearizing controller is
presented. The problem of ?nding the appropriate weights of the control law’s terms
is treated as an optimization problem. Given the highly ...
Numerical Modeling of Nasal Cavities and Air Flow Simulation
(2008-09-09)
Computational fluid dynamics (CFD) has many applications in biomedical engineering, such as simulating air dynamics in nasal cavities and lungs, blood flow in vessels, and blood flow in hearts. To perform CFD simulations, ...
Packaging of Silicon Carbide High Temperature, High Power Devices - Processes and Materials
(2008-09-09)
Silicon carbide (SiC) has unique electrical, thermal and physical properties compared to the Si and GaAs conventionally used in microelectronics as it can operate in the temperature range from 350ºC to 500ºC. However, there ...
A Technique for the Measurement of Relative Velocity between Parallel Plate Electrodes in Micromachined Structures
(2008-09-09)
Numerous applications exist for microstructures that contain two parallel oriented electrodes that experience relative motion. It is often desirable to measure the relative velocity between the two electrodes and then ...
Microcontroller-Based Current-Mode Control for Power Converters
(2008-09-09)
Presented in this dissertation is the implementation of microcontroller-based digital current-mode control (CMC) switch-mode power converters. A hybrid control method is proposed. By using on-board analog peripherals on ...
Compact Modeling of SiGe HBTs Using Verilog-A
(2008-09-09)
SiGe HBTs, integrated with CMOS, have demonstrated their usefulness in digital
and analog circuit designs for wired and wireless telecommunication applications over
the past decade. Of critical importance to successful ...
Applications of Multi-channel Filter Banks to Textured Image Segmentation
(2008-09-09)
Multi-channel filtering provides a robust solution to the texture discrimination/
segmentation problem for digital image processing. Specifically, the use of the Gabor
filter for channel characterization is explored. Tag ...
GPS and Inertial Sensor Enhancements for Vision-based Highway Lane Tracking
(2008-09-09)
For the past decade much research in the Intelligent Transportation Systems (ITS)
community has been devoted to the topic of lane departure warning (LDW). A significant
portion of highway fatalities each year are attributed ...
Vibration Analysis Of Test Chips With Integrated Piezoresistive Stress Sensors
(2008-09-09)
Vibration analysis of the WB200 test chip containing an array of optimized piezoresistive stress sensor rosettes has been performed. The test chip was attached to the printed circuit board with an underfill encapsulant ...
