Dynamic optimal dispatch of real power for thermal generating units
(1972)
A primary objective in electric power system operation is the scheduling of the real-power outputs of generators to minimize total fuel consumption while supplying all load requirements. This scheduling process is known ...
The mutual impedance between concentric curved dipole antennas above a spherical conducting surface
(1969)
In this paper an analytical expression is derived for the mutual impedance between concentric curved dipole antennas located in close proximity to a conducting sphere. The boundary value problem is solved using the spherical ...
Maximum-likelihood detection of uniform convolutional codes
(1969)
An algebraic decoding algorithm for the maximum-likelihood detection of uniform convolutional codes is developed. Coded signals are assumed transmitted over a coherent PSK channel which is corrupted by additive white ...
Parallel and intelligent test system architecture for circuit board interconnects
(1992)
In this dissertation, a parallel and intelligent test system is studied to detect the open circuit faults and the short circuit faults of printed interconnection circuit board. The printed circuit boards are composed of ...
Digital estimation of autocovariance functions and power spectra from randomly sampled data using a lag product technique
(1976)
The estimation of autocovariance functions and power spectra from randomly sampled data is a signal processing problem with applications in several areas. A practical autocovariance estimator produces estimates at integer ...
Multi-area power system reliability modeling
(1992)
The dissertation presents a transmission network model suitable for use in multi-area reliability models which utilize a Monte Carlo simulation approach. The transmission network model utilizes the REI equivalent which ...
Spread spectrum slotted ALOHA packet radio networks with near- perfect multi-packet capture
(1993)
This dissertation considers spread spectrum slotted ALOHA packet radio networks employing direct sequence spread spectrum signaling, discrete time of arrival randomization, an optimum delay capture mechanism, and multiple ...
Optimal imaging geometry for vision-based tracking systems
(1993)
When vision sensors are used to track an object in an outdoor realistic navigational environment, they are subjected to unexpected movements or vibrations of the mounting platform. In this dissertation, the performance of ...
Some new approaches to improve the power factor and reduce harmonics in three phase rectifier type utility interfaces
(1994)
In the recent years there has been a significant increase in the use of power converter equipment for variable speed ac/dc motor drives, emergency and standby power supplies for critical loads, magnet power supplies etc. ...
The circular cavity for antennas, periodic structures, and power combiners
(1994)
Circular cylindrical cavity resonators have been studied in three configurations. First, a slot antenna backed by a circular cylindrical cavity was analyzed. The resonant frequency of the cavity is found using power ...
