New passive and active filtering techniques for the mitigation of power system harmonics and to reduce the effects of high frequency PWM switching on the operation of AC motor drives
(1995)
With the increased attention on high efficiency and energy
Efficient optimization algorithms for constrained power economic dispatch
(1995)
Efficient optimization algorithms are developed to solve
Position sensor elimination techniques for synchronous reluctance motor
(1994)
Synchronous reluctance motor drives have recently received renewed attention. This interest is mainly due to modern field oriented control strategies, which have recently been applied to these motors. In particular it ...
Frequency stabilization of a traveling-wave semiconductor ring laser using a fiber resonator as a frenquency reference
(1995)
A fiber ring resonator with a temperature drift rate of better than 5 x 104 'C/hour is used for controlling the frequency of a 1.3-lim-wavelength external cavity semiconductor ring laser. This thesis describes the design ...
Analysis and design of low rate tree codes
(1989)
We consider here the problem of delayed decision source coding using integer and fractional rate tree codes. First, we investigate the performance of path map symbol release rules when used with exhaustive searching of the ...
Polarization independent optical switches using an off diagonal electrooptic coefficient in lithium tantalate
(1988)
Polarization independent optical coupled waveguide switches have been produced in lithium tantalate using the recently developed zinc vapor diffusion technique. Diffusion and fabrication process are described in detail. ...
The radiation zone fields of the stepped dielectric rod antenna excited in the HE₁₁ mode
(1967)
In this work analytical expressions are determined for the radiation zone fields of the stepped dielectric rod antenna with HE₁₁ mode excitation. This type of antenna is similar to both the cylindrical dielectric rod antenna ...
An Intel 8080 microprocessor implementation of a navigation algorithm for the low-cost GPS receiver
(1977)
The feasibility of a microprocessor implementation as a part of a low-cost GPS receiver is described. A noisy model is considered in the dynamic system simulation consisting of a C5A flight from California to Hawaii with ...
Some electron transport properties of two wide bandgap semiconductors, gallium phosphide and indium gallium phosphide
(1985)
Electron transport in gallium phosphide epilayers and indium gallium phosphide epilayers lattice matched to GaAs has been studied. The epilayers were grown using LPE with a graphite slider boat in a palladium diffused ...
