A Proposal For Two Computers Dealing With The Convolution Integral, Charles S. Williams Jr.

Electrical and Computer Engineering ETDs

The integral f(x) = g(x-y)h(Y)dy is known as a convolution integral. The first computer described herein will determine the function f when the functions g and h are known. The second computer will determine the function h when f and g are known; in using the second computer to find h, then the first computer is used for auxiliary computations.

A Study Of Servomechanism Damping Methods, Arthur J. Clark Jr.

Electrical and Computer Engineering ETDs

The purpose of this study is first to present a review of the general effects of damping, both Coulomb and Viscous, and feedback devices resulting in error rate damping: second to present detailed mathematical analyses of a number of special damping devices that may be used to advantage in servomechanism design.

A Variational Approach To The Calculation Of Electron Trajectories, Edmund G. Franzak

Electrical and Computer Engineering ETDs

It is the object of the present work to derive, develop, and illustrate a method for the calculation of electron trajectories based on variational techniques and employing scalar and vector potential functions instead of the customary intensity functions. The methods of the calculus of variations furnish an extremely basic approach to the problem while lending an undeniable air of rigor and mathematical elegance.

Solution of the problem will be accomplished by first setting forth a mathematical structure upon which the work will be based, next outlining the physical principles governing the problem and finally applying the mathematical theory and physical …
