Industry Participation In Electrical Engineering Education-Extra High Voltage Laboratory, J. Derald Morgan
Industry Participation In Electrical Engineering Education-Extra High Voltage Laboratory, J. Derald Morgan
Electrical and Computer Engineering Faculty Research & Creative Works
A unique electrical engineering laboratory course is described. This laboratory is an example of how industry can cooperate with universities in engineering education. The organization and operation of the course as well as the course material is outlined and explained, including the ways in which the industry participates in the operation of the laboratory. The educational benefits derived from such a cooperation between industry and the university are briefly detailed. These benefits are extended to the student, the University, the faculty, and the participating industry. This article provides the framework on which other laboratory experiences could be conceived and developed …
A Gamma-Level Portable Ring-Core Magnetometer, Stanley V. Marshall
A Gamma-Level Portable Ring-Core Magnetometer, Stanley V. Marshall
Electrical and Computer Engineering Faculty Research & Creative Works
A four-transistor circuit is described for a battery-operated magnetometer that has 0.1 γ resolution using t-in diameter 4–79 or 6–81 Mo-Permalloy tape cores of 20–40 Mx capacity. The center-tapped drive winding also serves as the sense winding, simplifying the sensor assembly. Some signal-to-noise results are presented to illustrate the fairly wide difference that may exist between cores of the same cross section and to demonstrate the advantage of reducing core area.

Deriving Dc Machine Torque By The Principle Of Virtual Work, George Mcpherson
Deriving Dc Machine Torque By The Principle Of Virtual Work, George Mcpherson
Electrical and Computer Engineering Faculty Research & Creative Works
The purpose of this paper is to fill a gap which exists in the "textbook" theory of dc machines. The paper shows that the usual expression for dc machine torque can be obtained from the direct application of the principle of virtual work to the machine, making the traditional assumptions. The method provides additional benefits in that it demonstrates the reluctance torque which results from the saliency of the field structure and shows that compensating windings have no effect on the torque under the assumed linear conditions.

A State Assignment Procedure For Asynchronous Sequential Circuits, Gary K. Maki, James H. Tracey
Electrical and Computer Engineering Faculty Research & Creative Works
This paper presents a new procedure for constructing nonuniversal shared-row internal state assignments for asynchronous sequential circuits. The method consists basically of establishing an initial code with the minimum number of variables required to dis. © 1971, IEEE. All rights reserved.

The Effect Of Channel Errors In The Differential Pulse-Code-Modulation Transmission Of Sampled Imagery, Roger J. Arguello, Harvey R. Sellner, John A. Stuller
The Effect Of Channel Errors In The Differential Pulse-Code-Modulation Transmission Of Sampled Imagery, Roger J. Arguello, Harvey R. Sellner, John A. Stuller
Electrical and Computer Engineering Faculty Research & Creative Works
This Paper Presents an Analysis, Simulation, and Discussion of the Effects of Communication Errors on Four-Bit Differential Pulse-Code Modulation (DPCM) Sampled Imagery. Simulations Are Presented that Describe the Effects of Inserting Periodic "PCM Updates" in Order to Correct Communication Errors in the DPCM Transmission of Photographic Scenes that Have Been Scanned and Sampled at the Nyquist Rate.

Maximum-Distance Linear Codes, Gary K. Maki, James H. Tracey
Maximum-Distance Linear Codes, Gary K. Maki, James H. Tracey
Electrical and Computer Engineering Faculty Research & Creative Works
Described here is a linear code that has a maximum distance between codewords of k for a code of order 2k. Since the minimum-maximum distance is k for a code of order 2k, a class of minimum-maximum distance codes results. For an (n,k) linear code, k ≤ n ≤ k + k∣2 for k even and k ≤ n ≤ k + (k - 1)/2 for k odd. Maximum-distance codes are found useful in encoding the states of sequential circuits. © 1971, IEEE.

Empirical Bayesian Learning, David R. Cunningham, Arthur M. Breipohl
Empirical Bayesian Learning, David R. Cunningham, Arthur M. Breipohl
Electrical and Computer Engineering Faculty Research & Creative Works
It is shown that a certain weighted average of the prior distribution and the empirical distribution yields an estimate of the posterior distribution that is consistent with Bayes' theorem. Acomparison of this approach and conventional parametric Bayesian estimation is made for some specific cases. Copyright © 1971 by The Institute of Electrical and Electronics Engineers, Inc.
