Geometric Tolerances, Clifford J. Joens

Graduate Research Papers

The writer teaches vocational drafting at the postsecondary level and has been unable to find suitable instructional material on the subject of geometric tolerancing. The existing books are either too lengthy and technical or are incomplete. Furthermore, none of them shows geometric tolerancing in the metric system, even though many of the industries which use geometric tolerancing also use the metric system. The purpose of this research project was to provide an instructional package to fill the void.

Problem Identification For Highway Safety Plan, Jerry G. Pigman, Kenneth R. Agent

Kentucky Transportation Center Research Report

To comply with Section 402, Title 23 of the United States Code, each state is required to prepare a annual highway safety program. Kentucky's program, which includes identification, programming, budgeting, and evaluation of highway safety projects, is intended to have a positive impact on the reduction of traffic accidents. The first step in the program, problem identification, requires systematic, statistical analyses of accident records. In-depth analyses of accident data were performed, and 25 problem areas were investigated. Accident rates were found for counties and cities in the following categories: total accidents, fatal accidents, accidents by driver age and sex, and …

A Technical Focus For Documenting The Effectiveness Of The Cooperative Owrt-Institute Water Resources Research Program, L. Douglas James

Reports

For years, the cooperative water resources research program of the Office of Water Research and Technology and the water resources research institutes in the respective states has been experiencing considerable difficulty in generating agency, congressional, and user support of a sort that attracts sufficient funding to maintain a dynamic research program. Efforts to increase support have included recruiting greater interaction with research user groups, expansion of the technology transfer program, cultivation of interaction of center directors and research users with congress, shifting requests for added funding within the research program from the allotment funding given the respective states to matching …

Energy In Agriculture: Energy For Greenhouses Part 1: Energy Conservation, George A. Duncan, John N. Walker, Larry W. Turner

Agricultural Engineering Energy Series

The increased cost and scarcity of all fuels have affected the greenhouse owner as badly as any segment of industry. For some, crops have been damaged or lost. For others, it has reduced the margin of profit. Growers, manufacturers, suppliers, horticulturists, engineers and many others have studied the situation thoroughly in order to come up with viable solutions and alternatives for conserving fuel.

Energy Fact Sheet: Heat Pumps For Residential Heating And Cooling: Some Questions And Answers, Larry W. Turner

Agricultural Engineering Energy Series

WHAT IS A HEAT PUMP?

A heat pump is an electrically-powered refrigeration cycle device which is capable of providing both heating and cooling to a residence. In the summer, it operates like an air conditioner by "moving" heat from inside the house to the outside. In the winter, the refrigerant flow is reversed, "moving" heat into the house by further chilling the already cold outside air and transferring the heat gained in the process to the inside.

An Evaluation Of Permissive Left-Turn Phasing, Kenneth R. Agent

Kentucky Transportation Center Research Report

In this study, exclusive left-turn phasing was replaced with permissive left-turn phasing at four trial intersections. Delay and accident studies were done before and after the trial installations. Also, a questionnaire was issued to determine public opinion concerning the signals.

The use of permissive-turn phasing resulted in a 50-percent reduction in left-turn delay and a 24-percent reduction in total delay compared to exclusive phasing. The permissive left-turn phasing did result in an increase in left-turn accidents. Other accident types, such as rear-end accidents, did not change. The number of left-turn accidents decreased as drivers became more familiar with the signals. …

The Effectiveness Of Regulatory School Flashers In Reducing Vehicle Speeds, Charles V. Zegeer, Robert C. Deen

Kentucky Transportation Center Research Report

Pedestrian safety for school-age children has been a growing problem in recent years. Children between the ages of five and nine represent less than 10 percent of Kentucky's population but over 16 percent of all pedestrian fatalities. A study was conducted to evaluate the effectiveness of regulatory school flashers used in school zones to reduce vehicle speeds and alert motorists of pedestrian activity and to determine measures which promote safety in school zones.

Speed studies were conducted during flashing and non-flashing periods at 48 school zones where regulatory school flashers were used. The locations involved a variety of speed limits …

Fatigue Damage Of Flexible Pavements Under Heavy Loads, James H. Havens, Herbert F. Southgate, Robert C. Deen

Kentucky Transportation Center Research Report

A modified Chevron N-Layer computer program has the capability of calculating the "work" done by the total load on a given load group. Earlier analyses of AASHO Road Test sections and test vehicles had permitted the development of damage factor relationships. This paper presents seven, namely two-tire and four-tire single axles, tandems, triaxles, and four-axle, five-axle, and six-axle groups. The two-tire axle (front or steering axle) has the most severe damage relationship. The 80-kN (18-kip) four-tire single axle was used as the reference axle and was assigned a damage factor of 1.0 for a specific amount of "work". Other axle …

Synchronization Strategies, Mishell J. Stucki, Jerome R. Cox Jr

All Computer Science and Engineering Research

Computing systems are now frequently composed of independently clocked subsystems that cooperate to perform the function desired for the whole. This type of architecture has many advantages and promises to be the standard for the foreseeable future. With the trend towards more and more gates per chip, the number of chips per subsystem gets smaller and smaller, and we can expect to soon see one or more subsystems per chip. This transition will require contributions from disciplines previously outside the field of chip design, and every issue will have to be carefully worked out beforehand because debugging chips of this …

Transformation Of Fresnel’S Interface Reflection And Transmission Coefficients Between Normal And Oblique Incidence, R. M.A. Azzam

Electrical Engineering Faculty Publications

If w denotes an interface Fresnel reflection or transmission coefficient for s- or p-polarized light at an oblique angle of incidence ø, and z denotes the same coefficient at normal incidence, we find that w is an analytic function of z, w = ƒ(z), that depends on ø but not on the specific optical properties of the two media on both sides of the interface. All four functions that correspond to the four distinct Fresnel coefficients and their inverses are determined. We single out for detailed examination, as an example, the relationship between the reflection of s -polarized light at …

Scalar‐Wave Approach For Single‐Mode Inhomogeneous Fiber Problems, Lee W. Casperson, Cavour W. Yeh, W. P. Brown

Electrical and Computer Engineering Faculty Publications and Presentations

It has generally been accepted that accurate results may be obtained using the scalar‐wave approach to solve problems dealing with inhomogeneous multimode guided‐wave structures. The problem of the applicability of the scalar‐wave approach to obtain wave propagation characteristics in single‐mode fiber or integrated optical circuit guides with inhomogeneous index profiles is examined in this paper. It is shown that if certain limiting conditions are satisfied, the scalar‐wave approach will yield valid results for single‐mode structures. These limiting conditions are usually satisfied by many practical single‐mode inhomogeneous fibers or IOC structures.
