Audio Triamplification System., John James Mccure

Electronic Theses and Dissertations

This thesis is for the purpose of determining if active filters are useful as audio crossover networks and in particular if they are better than passive crossover networks. An entire audio reproduction system was constructed with the express design intent of linear operation in two separate modes. These two modes being, first, a conventional single power amplifier passive crossover system, and second, an active filter triamplification system. Both systems were subjected to three different objective tests and one subjective test. The subjective testing included a wide spectrum of listeners ranging from rank amateurs to highly trained recording and mixing engineers. …

Sld Potamology Study (S-9), Jerome A. Westphal, Samuel P. Clemence

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Foreword

In this report, the authors discuss factors which relate to flow characteristics of the Middle Mississippi River and its major tributaries. The variety of ways in which man and nature interact to affect the hydrologic regime of the study area are almost infinite. Furthermore, the intensity and direction of man's activity is non-uniform with respect to both time and space. Therefore, on the scale of the study area, the authors assert that 1) it is difficult to verify associations between specific human actions and river responses and 2) at this time, it is impossible to do so in a …

Analysis Of Time-Independent Consolidation Data, E. Gregory Mcnulty, Tommy C. Hopkins, C. Thomas Gorman

Kentucky Transportation Center Research Report

The one-dimensional laboratory consolidation test developed by Terzaghi permits deformation and drainage only in the vertical direction. The stress-strain characteristics of data obtained from this test are normally studied using a semilogarithmic graphical representation, that is, vertical strain or void ratio is plotted as a function of the logarithm of effective stress. Such a representation permits an analysis of the stress history and compressibility characteristics of soils. Knowledge of these material characteristics is of great practical value in the prediction of settlement associated with loading where the effects of lateral consolidation may be neglected.

The National Solar Heating And Cooling Information Center, Jeremy A. Lifsey, Sanford Zane Meschkow

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The Center is an information service funded by the U.S. Department of Housing and Urban Development and the U.S. Department of Energy as part of a program to foster the use of solar energy in domestic hot water systems and the heating and cooling of buildings. The Center answers questions by mail and over toll-free hot lines, operates a mobile exhibit van and several exhibits that appear at conferences and trade shows, and distributes HUD and DOE publications on solar energy. Users can request lists of addresses of solar design and construction professionals, manufacturers, distributors, banks that have given solar …

Direct Solution Of The Isothermal Gibbs-Duhem Equation For Multicomponent Systems, José A. Martinez-Ortiz, David B. Manley

Chemical and Biochemical Engineering Faculty Research & Creative Works

The numerical solution of the relative volatility form of the isothermal Gibbs-Duhem equation for multicomponent systems Is carried out by a relaxation technique for two ternary systems at five different temperatures. This direct method of solution eliminates calculating and differentiating the excess Gibbs free energy as required by other indirect methods. © 1978, American Chemical Society. All rights reserved.

Measurement Of Poisson's Ratio And Tangent Modulus Of A Loess, Craig Randall Bowers

Masters Theses

"A series of triaxial tests are used to develop mathematical models for tangent modulus and Poisson's ratio for a remolded loessial soil. These two models are then utilized in a finite element computer program to model the behavior of a shallow foundation placed on compacted loess. Different models for Poisson's ratio gave widely varying load settlement curves, however a constant value of .32 gave results very similar to that given by the experimentally developed model. It was found that the model developed for tangent modulus yielded unreasonable results when utilized in the finite element analysis until a limiting value was …

A Study Of A Buoyancy Balanced Gas-Liquid Contacting System, Jaw-Ruey Leu

Chemical and Biological Engineering ETDs

In a conventional gas-liquid contacting system that provides a long gas-liquid contact time, a pressurized gas is released at the bottom of a pool of liquid to form gas bubbles; the bubbles move upward through the liquid and break at the surface of the liquid. A large amount of work is spent in pressurizing the gas. Even though it is theoretically possible to recover work from rising bubbles, a work recovery scheme has not been incorporated into a conventional system.

A buoyancy-balanced gas-liquid contacting system concept has recently been introduced. The system comprises two processing zones filled with a liquid, …

The Effects Of Certain Impurities And Their Interactions On Zinc Electrowinning, Donald R. Fosnacht

Doctoral Dissertations

“The effects of germanium, antimony, arsenic, cobalt, glue, and free acid concentration were studied on both commercial and synthetic electrolytes. The effects of a single factor and the combined effects of multiple factors were elucidated. The temperature, zinc concentration, and current density were also varied. It was found that the acid concentration was the most critical factor when impurity levels were at normal plant solution concentrations. The ranges where the effect of the impurity became apparent were: greater than 20 ppb for antimony; 40 ppb for germanium; 120 ppb for arsenic; and 7-8 mg/l for cobalt for a solution containing …

Conference Tutorials-An Opportunity For Continuing Education, John H. Park, William H. Tranter

Electrical and Computer Engineering Faculty Research & Creative Works

The Educational Services Committee of the IEEE Communications Society has sponsored eleven tutorial short courses at its major conferences over the past six years. The experience gained in developing and presenting these tutorials is shared with others so that they may be in a better position to sponsor similar continuing education activities in the future. The conference tutorial is one example of a continuing education activity that can be sponsored by an IEEE Group or Society as a service to its members.
