Influence Of Recreational Areas On The Functional Service Of Highways, Jerry G. Pigman

Kentucky Transportation Center Research Report

Development of outdoor recreational facilities in Kentucky has generally been in predominately rural areas. Access to these areas from the primary highway network is often provided by existing low-standard local roads. The recreational travel demand often exceeds the design volumes of these local roads or the volumes that can be accommodated at reasonable levels of service. Such travel demand also constitutes a significant portion of the total demand on the rural primary network, particularly during the peak weekend periods.

Many large reservoirs in Kentucky have generated extensive developments of recreational facilities in the surrounding areas. Highways which have been displaced …

Mechanical Lettering Devices For Drafting, Wilson G. Forbes

Graduate Research Papers

Having taught mechanical drawing in high school, grades nine through twelve for nearly six years this writer has stressed the importance of lettering to students many times. However, freehand lettering is a very short unit, with limited experience using a Leroy Lettering Guide. The desire to discover other means of lettering drawings prompted the selection of this topic.

Production Of A Video Tape Recorded Supplement For Use In Teaching Electrical Tuned Circuit Theory, William A. Carlson

All Master's Theses

This paper presents a sample of the proceedures utilized to produce a video tape recorded suppliment for use in teaching electrical tuned circuit theory. It is designed so that it could be used as a ready reference for anyone desiring to make a video tape recorded teaching aid. A recomendation is that, with the advent of the simplified video tape recorder, every teacher should become as practiced in its operation and utilization as he now is with the film projector.

Computer-Assisted Layout Design Planning For An Entree Production Center, Saundra H. Pierpoint

Loma Linda University Electronic Theses, Dissertations & Projects

A productive layout design effectively utilizes men, materials, machines, and space. Determination of effective utilization of space and equipment arrangement for a food service system is based on the menu item production sequences. Utilization of computer processing of the data can provide quantitative information in minimal time for major planning decisions.

It was the purpose of this research 1) to determine an optimal equipment arrangement among four types of layouts for an entree-production center and 2) to demonstrate the value of the computer-assisted method in optimizing equipment arrangements.

The production sequences indicating equipment utilization and frequency factor for each of …

4. experiment with the possibility of making photodrawings without the use of a darkroom.

Tobacco Plant Harvester, James H. Casada, Edward M. Smith

Biosystems and Agricultural Engineering Faculty Patents

A harvester for tobacco plants is provided for towing by a prime mover to which an articulated frame is attached, the frame mounting a movable turret having spears on which tobacco stalks are impaled. During removal of the stalks from the spears, they are loaded on sticks which are then manually removed from the harvester.

A hydraulic system powered from the prime mover serves to actuate each of the turrets, an empty stick supplying mechanism, a loaded stick removing mechanism, and the mechanism for transferring stalks from the spears to the sticks; and a mechanical power takeoff shaft driven by …

A Study Of Dr. Donald Maley's Theory -- "Research And Experimentation In Industrial Arts", John Edward Ferree

Graduate Research Papers

The problem of this study is to make a thorough examination of Dr. Donald Maley's theory -- "Research and Experimentation in Industrial Arts in the Junior or Senior High School."

Perhaps now in 1968, more than ever, concern for what is in store for industrial arts is, or should be, considered more "grave" than expressed in the above quote of Dr. Maley in 1959. Certainly now it could generally be agreed that all theories concerning the future path of industrial arts, of which Dr. Maley's Research and Experimentation theory is one, deserve a full measure of study and evaluation by …

Centering In Parallel Channel Systems, Allen Katz

Dissertations

Several types of signal processing systems in which the signal flows along parallel channels in a fashion similar to the auditory system have been investigated. The effect of excitation with signals containing both single and multiple spectral peaks (formants) was considered. In particular, the effect of nonlinear interaction between channels, referred to as centering, in the presence of noise was studied.

These systems were investigated for their value, both as information processing networks and as models of the auditory system.

The analysis indicates that parallel channel systems, in general, exhibit excellent performance in the presence of noise, and that a …

Computer Model For Reactor Design Of An Ethane Cracking Unit, Derek J. Lough

Theses

The purpose of this thesis is to develop a Fortran [sic] Computer Program to model the radiation section of a pyrolysis tube reactor designed for cracking 100 percent ethane feed. The model calculates the length of the tubular reactor required to obtain a specified ethane conversion or the ethane conversion for a specified reactor length. The resulting solution yields a conversion profile, a temperature profile, and the reactor residence time as a function of tube length. From this data it can be determined if the design is adequate and lies within the reactor model's constraints.

A Nomograph For The Rapid Solution Of The Arrhenius Equation, Joseph John Lamont

Theses

There are presently no calculational aids for the rapid computation of the Arrhenius parameters of the chemical reaction rate equations.

Two nomographs for solving the Arrhenius equation for the relative reaction rate constants at different temperatures, and for computing activation energies and frequency factors are presented. Several graphs and tables of the relative reaction rate constant as a function of activation energy and temperature are also presented.

The nomographs, graphs and tables can be used, singly or combined, in lieu of numerical calculation for the solution for Arrhenius parameters, or the computation of rate constants.

A Simulation Model Capable Of Performing The Calculations Involved In Defining A Crude Preheat Train, Robert G. Parker

Theses

A simulation model has been developed for a system of ex changers to preheat the feed to a crude distillation unit. In conjunction, a Fortran program for the performance of the model calculations by digital computer was written. Two types of preheat system were simulated, a single train system and a split (or parallel) train system. A number of features were included in the program for flexibility and versatility. A particular effort was made to have the model represent as economical a preheat system as possible.

The model program was used to obtain computer-calculated results for both single-train and split-train …

Incineration Of Solid/Liquid Human Waste, Theodore Joseph Wayne

Theses

This thesis encompasses the design criteria required to produce an effective incineration system for the disposal of solid/liquid human waste. Coupled with the overall design parameters is an investigation of the chemical decomposition of the waste during the incineration process, odor treatment and control, and the physiological effects on the human body due to the inhalation of the toxic gases given off during the combustion of human waste.

The variables involved in the combustion process are studied and equations presented that relate the combustion variables of flame temperature, residence time and air requirements. These equations are tested based upon published …

Arctic Ecology: A Decade Of Experience, John F. Schindler

UMR Journal -- V. H. McNutt Colloquium Series

A quick glance at the title of this presentation and the reader braces himself for another antipollution or “save-the-sod” type of discourse that has become so popular these days. I do not wish to detract from the importance or the need for such efforts but I would like to address myself to the the broader meaning of the term.

Ecology--the word comes from the Greek root “oikos” which means house or household. What I’d like to do is to tell you about this “house” I’ve been living in for the past 10 years.
