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. ...
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 ...
A numerical approach to the solution of cylindrical waveguide with discontinuities
(1986)
The wave scattering due to discontinuities in a cylindrical structure with axial symmetry has many applications. Borehole geophysical exploration, wave propagation in optical fibers, and metallic waveguide junctions are a ...
A stereo model based on the mechanisms of human binocular vision
(1986)
In computer vision, the idea of using stereo cameras for depth perception has been motivated by the fact that in human vision one perception can arise from two retinal images as a result of a process called 'fusion'. ...
Monolithic fully balanced OTA based high frequency filters
(1987)
This research involved the development of a design approach and the necessary circuit elements for high-frequency continuous-time monolithic filters to be implemented in a standard CMOS process. The investigation began by ...
Reliability evaluation of bulk power systems
(1986)
The increasing size and complexity of power systems, coupled with present day financial constraints have made the use of probabilistic methods and reliability indices a necessity in order to maintain the continuity and ...
Shape discrimination and assembly of scattered regional pieces by Psi-S curve
(1987)
One of the fundamental problems of shape discrimination by machine vision is the object matching based on the boundary information. Subsequently, precise edge detection has been the main issue in this field. New techniques ...
A special purpose architecture for a real-time stereo vision model
(1989)
A high-speed special purpose architecture is developed to implement a stereo vision model for an autonomous vehicle application. The design criteria are high speed, low complexity, and good portability. The main computational ...
An intelligent decision making system for detecting high impedance faults
(1989)
The clearing of distribution line faults is usually accomplished by devices which can sense the overcurrent produced by a fault and react to disconnect the faulted section of the feeder from the healthy section. However, ...
