Advanced modulation techniques for power converters
(2007-09-14)
Pulse-width modulation methods are widely used for the synthesis of ac voltages at
the terminals of a voltage-sourced converter (VSC). Traditionally sinusoidal pulsewidth
modulation (SPWM) has been used. A powerful ...
A comparison of imaging methods using GPR for landmine detection and a preliminary investigation into the SEM for identification of buried objects
(2005-01-13)
Part I:
Various image reconstruction algorithms used for subsurface targets are reviewed. It is shown how some approximate wavefield inversion techniques: Stripmap Synthetic Aperture Radar (SAR), Kirchhoff Migration ...
Modeling and design of an electric all-terrain vehicle
(2009-01-15)
This thesis describes and evaluates the conversion of a conventional gasoline powered all-terrain vehicle (ATV) to an electric ATV. Preliminary studies are performed to obtain initial power and torque requirements for the ...
Design of a sixteen channel anterior cardiac receive coil for parallel imaging at 3T
(2007-04-27)
The main objective was to construct a 16-channel anterior cardiac array for 3T MRI capable of ⅓ mm pixel resolution across the right coronary artery, while achieving favourable parallel imaging characteristics. Based on ...
