Attitudes Towards Quality In The Design And Construction Of Nuclear Power Plants, Daniel L. Babcock, Larry G. Harmon

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

Adequate regulation of construction (and operation) of nuclear power plants has become a matter of growing national concern. Published statements by individuals speaking from two viewpoints, those of the regulatory agencies and the nuclear power industry, suggest divergent attitudes. Nineteen statements from these two points of view were evaluated for agreement or disagreement by 38 knowledgeable persons from both industry and government (of 50 solicited in a mail survey). Survey results showed a general appreciation of the need for some level of regulation and also for the possibility of over-regulation. Differences existed within as well as between the two groups, …

Computer Storage Of Traffic Volume Data, Marvin Virgin

Kentucky Transportation Center Research Report

LOADVOL is a program developed to assimilate raw traffic volume data into a more readily usable form. Several identifying parameters are added to enhance the clarity and to extend the utility of the data base.

Criteria were set to detect possibly erroneous traffic count data. LOADVOL detects and replaces "erroneous" data with simulated data. LOADVOL produces cards which contain the orignal data which are replaced. Thus, the original data can be reviewed, and it can be ascertained whether it is erroneous or was affected by a special event, holiday, location, traffic recorder malfunction, or some other occurrence.

UPDATE, a second …

Single-Element Rotating-Polarizer Ellipsometer For Film-Substrate Systems, A.-R. M. Zaghloul, R. M.A. Azzam

Electrical Engineering Faculty Publications

A novel and very simple ellipsometer for the characterization of film-substrate systems that employs one rotating optical element (a polarizer) is proposed. The ellipsometer is based on detecting the angles of incidence at which a film-substrate system has equal amplitude attenuations for light polarized parallel (p) and perpendicular (s) to the plane of incidence. At a certain wavelength, the film thickness of the filmsubstrate system has to lie within permissible-thickness bands (PTB) for the technique to apply.

An Investigation Of Low Cylinder-Strengths (District 6), Assaf S. Rahal

Kentucky Transportation Center Research Report

District 6 has had a lingering problem of low cylinder-strengths. This report describes, in detail, an ensuing investigation which incorporated the use of identical materials of concretes used in District 6 and analyses of cylinder data, in situ concrete cores, and laboratory mixtures. The investigation revealed that a high percent of the in situ concrete is sound and reliable, and that aggregate type and (or) air content were not the cause for the low cylinder-strengths. The quality of making, storing, and curing the cylinders were the reasons for low-strength.

Statewide Survey Of Skid Resistances Of Pavements (1976), James L. Burchett, William M. Sampson, Larry A. Warren, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

Statewide survey of skid resistance continued in 1976 with testing of rural, major, collector roads (1985 Functional Classification). This included 5,074 miles (8,166 km) of state secondary roads and 788 miles (1,268 km) of rural secondary roads. About 17 percent of the secondary mileage and about 15 percent of the rural secondary mileage surveyed in 1976 may be considered slippery. A small percentage of both secondary (5.3 percent) and rural secondary (5.8 percent) roads had an average skid number below 26. These sections, in particular, should be flagged for deslicking.

Through 1976, 50 percent of the mileage of rural, state-maintained …
