A. C. Power Losses In Mov Surge Arrestors, Alan J. Engelmann, W. L. Weeks May 1988

A. C. Power Losses In Mov Surge Arrestors, Alan J. Engelmann, W. L. Weeks

Department of Electrical and Computer Engineering Technical Reports

It was the objective of this study to measure power losses occurring in MOV surge arrestors as they were subjected to various voltage Excitations. In particular, power losses were observed in two MOV devices as sinusoidal voltages of different magnitudes were applied, at various frequencies in the range of typical power frequencies and common harmonics. Power losses were also observed in an MOV device for applied voltages consisting of the sum of 60 Hertz sinusoids and a single harmonic. The measurement procedure consisted of obtaining digital records representing the waveforms of voltage across and current through the MOV device during …

Prospectus For A Remote Pasm Execution And Debugging Environment - Pdb, Thomas L. Casavant, James E. Lumpp Jr, Thomas Schwederski, Wayne Nation Apr 1988

Prospectus For A Remote Pasm Execution And Debugging Environment - Pdb, Thomas L. Casavant, James E. Lumpp Jr, Thomas Schwederski, Wayne Nation

Department of Electrical and Computer Engineering Technical Reports

This document describes four design alternatives for a remote debugging and execution environment for the PASM Parallel Processing System Prototype in the School of EE at Purdue. Two alternatives involve acquisition of modest hardware for system enhancement, while the others are software-only solutions. All solutions involve use of a high-resolution bit-mapped graphics device, mouse and keyboard input, and a broad-band Ethernet-like communication medium. These latter components are currently available. The goal of this environment is to support any type of debugging which is currently supported by using the front panel of the machine and several terminals which are manually multiplexed …

Reflection Mode Diffraction Tomography, Barry A. Roberts, A. C. Kak Feb 1988

Reflection Mode Diffraction Tomography, Barry A. Roberts, A. C. Kak

Department of Electrical and Computer Engineering Technical Reports

In the field of ultrasound diffraction tomography, a cross section of a weakly scattering object is reconstructed from measurements of the sound scattered from the insonified object. This research studies tomographic imaging algorithms that deal only with the sound that is backscattered from the object. The use of the backscattered sound provides higher resolution reconstructions due to the higher spatial frequency information about the object that is obtained from the backscatter. Unfortunately the cost of the high frequency information contained in the backscatter is the loss of low frequency information. Different approaches to compensate for this loss are discussed. An …
