Analysis Of The N-Wire Exponential Line, Edward C. Bertnolli Jan 1967

Analysis Of The N-Wire Exponential Line, Edward C. Bertnolli

Electrical and Computer Engineering Faculty Research & Creative Works

A new approach to distributed network analysis is presented with the analysis of the n-wire exponential line as example. This approach provides the distributed network's transfer matrix in a form useful for both transient and steady-state network calculations. © 1967, IEEE. All rights reserved.


Annealing Characteristics Of Neutron Irradiated Silicon Transistors, J. R. Chott, C. A. Goben Jan 1967

Annealing Characteristics Of Neutron Irradiated Silicon Transistors, J. R. Chott, C. A. Goben

Electrical and Computer Engineering Faculty Research & Creative Works

When a transistor is subjected to neutron irradiation, a component of base current proportional to neutron fluence is induced. From the effects of annealing on the base and collector Currents the conclusion was drawn that there is an apparent difference in the annealing characteristics between the neutral and the space-charge regions of the semiconductor device. This study of the anomalous annealing indicates that the neutron-induced component of base current is a result of one, or a combination, of the following mechanisms: A quasi-tunneling recombination phenomena in the emitter-base space-charge region, or an influence of the p-n junction electric field on …

An Analytic Model For The Fluxgate Magnetometer, Stanley V. Marshall Jan 1967

An Analytic Model For The Fluxgate Magnetometer, Stanley V. Marshall

Electrical and Computer Engineering Faculty Research & Creative Works

The output voltages from various fluxgate probe types are found to have the same general form, and an analytic model has been developed with which the output may be calculated. In the saturation region where the output pulse is developed, the differential permeability can be closely approximated by an exponential, dB/dH = k1Hk2, where kl and k2 are on the order of 100 and -2.0, respectively, for cores of Supermalloy or Permalloy 80. Using this model, the effect of the nature of the excitation function on output pulse amplitude and width and the effect …


Analysis Of Conductor Vibration, Robert H. Nau Jan 1951

Analysis Of Conductor Vibration, Robert H. Nau

Electrical and Computer Engineering Faculty Research & Creative Works

Considerable attention has been given to conductor vibration of suspended transmission lines during the past 25 years. Even so, the engineers of the public utilities feel that they have only started to get a solution to the vibration problems. Extensive research programs are being conducted at the present time by manufacturers of conductor cable and ground wires and by numerous public utilities themselves.

Aeolian vibrations are the chief concern because they occur whenever a steady wind, of from one mile per hour to hurricane velocity, blows across the suspended line. Thus, millions of flexures, however small or large in amplitude, …
