Energy Conservation In Buildings -- The Missouri Plan, Jack Whittier, Bill Jurkiewicz, Weston Fisher

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

In 1974, approximately 23 percent (256.5 trillion Btu's) of Missouri energy was consumed in the residential sector. In 1980, this figure is projected to be 246.6 trillion Btu's (21 percent) (ref. 1). The reduction reflects already implemented conservation activities and the increased use of electric heating at higher end point efficiency. Estimates suggest that energy savings of nearly 50 percent could be achieved in this sector, primarily by upgrading the thermal efficiency of building structures and changing user behavior patterns. This given potential, the reduction of energy consumption in this sector has become a major target of the Missouri Energy …

Attainability And Nonattainability Under Anti-Pollution Laws, J. David Reed, John H. Hoag

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

The central issue with which this paper deals is the effectiveness of alternative air pollution control standards presently in use in the United States. More specifically, an analysis and comparison of effluent air standards versus ambient air standards will be performed. The question of effectiveness will be in the context of how well the alternative pollution control measures achieve society's expectations as goals when the standards are imposed. Society's views are assumed to be reflected through a regional (state) planner. The analysis is performed through the use of optimal control techniques. Initially the effluent air standards model will be examined. …

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 …

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.

Evaluation Of Urban Intersections Using Traffic Conflict Measures, Mike E. Clayton

Kentucky Transportation Center Research Report

The purpose of this report was to analyze two urban intersections using conflict data, erratic maneuver data, and near-miss accident data and to recommend site improvements, if necessary. The two intersections selected were Euclid Avenue at Woodland Avenue and New Circle Road at Woodhill Drive in Lexington. Data were taken using 11-hour observation periods.

Proposed improvements for the site on Euclid Avenue included adding dual left-tum lanes and three-phase signals or an extended multi-turn lane. At the New Circle site, a longer, more gradual right-turn lane and repositioning some of the signing are recommended. The conflict data recorded were found …

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 …

Aasho Road Test Tandem Axleload Data Adapted To Fundamental Concepts, Herbert F. Southgate, Robert C. Deen, James H. Havens

Kentucky Transportation Center Research Report

The reptitions of tandem axleloads applied to the AASHO Road Test were analyzed by the same method previously reported in analyzing the corresponding single axleload data. The essential findings were: 1. One repetition of a 34-kip (151-kN) tandem axleload appears to cause the same damage as one repetition of an 18-kip (80-kN) single axleload. 2. The relationship of log repetitions versus axleload used by Kentucky appear to be equally valid for single and tandem axleloads. 3. The use of superposition principles, and equivalency of repetitions, in combination with terminal serviceability indiced permitted analyses of the tandem axleload data and comparison …

Nonlinear Buckling Of Deep Cylindrical Shell Panels With Imperfections, Madhusudan H. Jhaveri

Dissertations

The work presented in this dissertation is devoted to the analysis of nonlinear buckling of thin cylindrical shells with imperfections. The nonlinearity of the problem treated in this dissertation is that associated with large displacements in the linear elastic range. The method used is not restricted by the magnitude of the displacements provided that the strains do not exceed the limit of proportionality.

Thus, based upon the large deflection theory, cylindrical shell panel is investigated for buckling under the action of uniform external pressure. Certain higher order infinitesimal terms which are usually neglected in the shallow shell theories, have been …

Growth Patterns Of Bacteria In Pressurized Sewage, Dennis Mazzei

Theses

Primary sewage was pressurized at 100 psi for one hour. The effects of this pressure on the growth patterns of general and nitrifying bacteria were examined daily for eighteen consecutive days using Standard Plate Counts and Most Probable Number (MPN) estimates. In conjunction with these tests, the degree of biodegradability was also determined by measuring both daily biochemical oxygen demands (BOD's) and dissolved oxygen levels.

Graphical analysis of experimental data compare the BOD's exterted [sic] by microorganisms to their respective numbers of colonies as determined by plate counts of both pressurized and non-pressurized sanitary sewage diluted to 3. 00%. The …

The Anisotropic And Isotropic Strength Behavior Of An Illitic Clay, Miles M. O'Brien

Theses

The cause and the nature of anisotropy in a cohesive soil was investigated by direct shear and triaxial compression tests. Laboratory techniques and procedures used to prepare isotropic clay samples are given where consolidation was accomplished under hydrostatic pressure. Direct shear tests were performed on these specimens trimmed at different inclinations to the physical horizontal from the block samples. The ratio of undrained shear strengths in any direction to shear strength in the vertical direction was found to be equal to one, proving isotropy existed. Similar tests were performed on specimens trimmed from the same clay consolidated one-dimensionally. Results from …

Effectiveness Of Green-Extension Systems At High-Speed Intersections, Charles V. Zegeer

Kentucky Transportation Center Research Report

The purpose of this study was to determine the effectiveness of green-extension systems (GES) for reducing the dilemma-zone problem associated with the amber phase of traffic signals at high-speed intersections. Reactions of 2,100 drivers were noted during the amber phase at nine intersections, and the dilemma-zone distances with respect to the stop bar were determined.

Before-and-after studies made at three green-extension sites showed a 54-percent reduction in total accidents and a 75-percent reduction in rear-end accidents after GES installation. Accident severity was unaffected.

Conflict, volume, delay, and speed data were taken before and after GES installation at two sites. A …

Traffic Accidents: Day Vs. Night, Donald R. Herd, Kenneth R. Agent, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

A comparison of accidents during daylight and darkness was made for both rural and urban roads. Accident rates on all types of rural roads were higher during darkness than during daylight. Critical accident rates during darkness for various types of roads were calculated. In urban areas, a larger percentage of accidents occurred on wet pavements during darkness than during daylight, but there were no significant differences for rural roads. No significant difference was found between average speeds during conditions of daylight and darkness. On rural roads, imposition of the 55-mph (24.6-m/s) speed limit resulted in a reduction in accident rates …

A Study Of Geologic Hazards And Geotechnical Input For Selected Critical Facilities - Cache Valley, Utah, Kenneth Robert Green

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Important public facilities located in Cache Valley, Utah, were studied to assess their exposure to geologic hazards. Also, the level of geotechnical and geologic expertise involved in the siting, design, and construction of critical public facilities was studied. A discussion of several individual facilities, that were exposed to some degree of hazard, was presented to illustrate the nature of the problem.

Earthquake hazards probably constitute the greatest threat to facilities and to the general welfare of the public. Many earthquake hazard mitigation measures were discussed and recommendations were made, based on aseismic design criteria which has been developed for seismically …

Salt Production From Micro-Channels In The Price River Basin, Utah, Richard Bruce White

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt production from micro-channels in the Price River basin of east-central Utah was studied using artificial inputs in order to better define the general sources and processes involved in diffuse source salt release within the basin. An attempt was made to determine what factors are most significant in relation to salt release. The study revealed that the micro-channel systems are highly heterogeneous in relation to salinity. This natural variability tends to increase as the salt content of the channel increases.

The Bluegate member of the Mancos shale was found to be the prime source of salt within the basin. Gypsum …

The Effects Of Pressure On The Biodegradability Of Sanitary Sewage In A Model Activated Sludge Reactor, Nicholas A. Mezei

Theses

Based on existing information concerning the effects of pressure on the biodegradability of sanitary sewage, a model activated sludge reactor was used in conjunction with pressurization to determine the viability of pressurization as a primary sewage treatment process.

Municipal sewage samples were pressurized at 40 psig for one hour with an excess of oxygen. An air compressor and a steel drum were used for sample pressurization. A non-pressurized control sample was maintained. After pressurization, the samples were fed into separate model activated sludge reactors. Biodegradability of both types of effluent was measured by determining their five day biochemical oxygen demands …
