An investigation of the radiated signals produced by small sparks on power lines
(1970)
This study reports the writer's findings about the time domain and frequency domain characteristics of the electromagnetic interference produced by the small-dimension, low root-mean-square current sparks which exist between ...
The input impedance of a gamma-matched dipole antenna
(1970)
The gamma match is a matching device which permits direct connection of a one-piece antenna element to a coaxial transmission line by adjustment of the physical dimensions of the gamma match. In this study, a mathematical ...
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, ...
The path integral time-domain method for electromagnetic scattering
(2000)
A full wave analysis of the electromagnetic field in the time-domain derived from R. P. Feynman’s path integral is examined. The propagator, which evolves the fields through successive time steps, comes from a state variable ...
Hardware support for high-level LISP functions
(1985)
The efficient execution of the LISP programming language is an important concern because of its use as a systems language for applications in Artificial Intelligence. Many architectures especially tailored for LISP have ...
Identification of plant parameters by application of implicit synthesis
(1964)
A new technique is developed for the characterization of an unknown dynamic plant. The technique is applied to simultaneously identify the unknown parameters A and B of a plant which is described by: A[d²X(t) / d²t] + ...
Use of finite element methods in solution of optimum distributed parameter systems
(1976)
The problem of designing an optimum distributed parameter system is considered. The necessary conditions for optimality are derived by applying the calculus of variation. Fundamental concepts pertaining to the solution of ...
Design and operation of a monolithic field emission triode
(1994)
Due to limitations of semiconductor-based microelectronics, a clear need for a superior technology exists. Field emission vacuum microelectronics is one such technology that possesses the potential to overtake the ...
Invariant pattern recognition system based on sequential color processing and geometrical transformation
(1994)
One of the most noteworthy problems associated with conventional pattern recognition methods is that it is not easy to extract feature vectors from images which are translation, rotation, and scale change invariant in ...
