Mechanical and Aerospace Engineering Faculty Research & Creative Works

Disclosed is a multiple output DC-to-DC converter. The DC input power is filtered and passed through a chopper preregulator. The chopper output is then passed through a current source inverter controlled by a squarewave generator. The resultant AC is passed through the primary winding of a transformer, with high voltages induced in a plurality of secondary windings. The high voltage secondary outputs are each solid-state rectified for passage to individual output loads. Multiple feedback loops control the operation of the chopper preregulator, one being responsive to the current through the primary winding and another responsive to the DC voltage level …

"An extensive experimental investigation has been conducted to study the load-carrying capacity of cold-formed steel web elements subjected to bending stress, shear stress, and a combination of bending and shear stresses. Emphasis has been concentrated on the instability and postbuckling strength of beam webs.

In the study of beam webs subjected only to bending, the postbuckling strength of web elements and the effect of the compression flange on the moment capacity have been carefully evaluated for beams having stiffened and unstiffened flanges. Based on 84 test results, formulas have been developed to predict the ultimate moment capacity of cold-formed steel …

Control Of Population Densities Surrounding Nuclear Power Plants, A. V. Nero, C. H. Schroeder, W. W.S. Yen

Faculty Scholarship

In view of the requirement that the California Energy Resources Conservation and Development Commission must specify land-use/population density control measures to be used in the vicinity of nuclear power plants being granted land use, the possible forms of such measures are examined. Since these measures must maintain population densities below Nuclear Regulatory Commission criteria, if appropriate, NRC criteria for land use and population densities are given particular attention. In addition, a preliminary comparison of the cost of possible control measures with the reduced potential for damage to the public health and safety is made, yielding the result that control measures …

Improving Qpsk Transmission In Band-Limited Channels With Interchannel Interference Through Equalization, S. H.R. Raghavan, Rodger E. Ziemer

Electrical and Computer Engineering Faculty Research & Creative Works

This paper describes the use of equalization in conjunction with channel filtering to improve QPSK transmission subject to both InterSymbol interference (ISI) and interchange interference (ICI). Performance bounds are computed using the nonclassical Gauss-quadrature rule (GQR) method. The signal-to-noise ratio (SNR) gain due to linear equalization over Non equalization is thereby obtained and presented. The performance of a linear equalizer thus obtained is compared with the Viterbi algorithm sequence estimator (VASE). In the absence of bounds for the VASE receiver under the channel conditions considered, simulation results are used to make the comparison. With a possible difference in the accuracies …

Classroom Analysis Of Various Plastics, Paul D. Harrington

Graduate Research Papers

In the junior high plastics course this writer. teaches, the students display more interest in the manipulative activities of the laboratory than in the sit-down classroom activities. The results of this tend to be a once-over-lightly treatment of the technical aspects of plastics and more hands on craft type activities in the laboratory. To bring more balance to the program, an activity needs to be devised which will have more industrial relevance. Such an activity should allow the students a certain amount of freedom and still provide them with technical information and acquaint them with the properties of various plastics. …

Accidents On Rural, Two-Lane Roads And Their Relation To Pavement Friction [Nov. 1976], Rolands L. Rizenbergs, James L. Burchett, Larry A. Warren

Kentucky Transportation Center Research Report

Friction measurements were made with a skid trailer at 40 mph (18 m/s) on 1460 miles (2350 km) of rural, two-lane roads (US routes) in Kentucky. Maintenance sections or subsections were treated as test sections. Accident experience, friction measurements, traffic volumes, and other available data were obtained for each. Various expressions of wet-pavement accidents and pavement friction were related and analyzed. Averaging methods were used in developing trends and minimizing scatter. A moving average for progressively-ordered sets of ten test sections and test sections grouped by Skid Numbers and Peak Slip Numbers yielded more definite results. The expression of accident …

An Experimental Study Of Semi-Continuous Ph-Parametric Pumping With A Center Feed, John S. Dell'osso

Theses

Parametric pumping represents a new development in separation science. It has attracted considerable attention both because of its novelty and because it permits continuous operation in small equipment with very high separation factors. The basic principle of parametric pumping is to utilize the coupling of periodic changes in equilibrium conditions caused by periodic changes in some intensive variables (temperature, pH, electric field, etc.), and periodic changes in flow direction to separate the components of fluid which flows past a solid adsorbent. Applications of parametric pumping involving the separation of valuable materials such as proteins would be very attractive and profitable …

The Impact Of Solar Central Electric Technology On The Regulated Utility, Donald A. Murry

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

The generation of electricity by solar energy in the U.S. is moving from the design stage to the pilot plant stage. Some persons have argued that at least some of the base line technologies are competitors now or are approaching parity with other energy sources, at least when the social costs and benefits are considered. This paper evaluates briefly the institutional framework of the regulated electric utility, the proforma impact of a solar electric plant upon an operational utility. We conclude that under the present regulatory/institutional framework, the solar electric technology will be developed at a date that is slower …

Optimal Fuel Supply Control For Electrical Energy Systems -- A Real Time Computer Technique, J. Derald Morgan, Richard Thomas Smith

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

The techniques of linear-integer programming are applied to the problem of supplying coal to power plants. A heuristic technique for optimizing the supply of coal to power companies is created. The optimization minimizes the purchase, transportation, and demurrage costs of coal subject to power system operations, power plant demands, coal purchase supply, power plant coal handling operations, and transport options. A procedure for calculation and analysis of cost sensitivity of optimal solutions to input data perturbations is presented which utilizes the optimizing technique.

The nature of the constraint set developed allows for the inclusion of loading and unloading operations in …

Over One Billion Tons Of Coal In 1985: Can The Railroad Industry Handle It?, Larry C. Peppers

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

Any evaluation of our country's resource potential must carefully consider the transport network and the constraints which it places upon future energy development and growth. The federal government has a vague goal of energy independence (or, at least, less energy dependence), but it has not developed a coherent energy plan—a critical element of which is energy transport. The paper analyzes the uncertain coal outlook facing the rail industry, translates these coal scenarios into alternative financial projections for the rail sector, and clarifies the most urgent federal decisions needed in the energy-transport policy matrix. The rail industry is being asked to …

On-Site Generation Of Electricity -- An Idea Whose Time Has Come, Thomas R. Casten

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

Generation of electricity, on-site, with recapture of waste heat can save many area concerns up to 50% on their total energy costs today and save up to 60% of the total fossil fuel presently used. The very favorable economics result from increased utility costs -- a phenomenon of the past three years. The efficient use of fossil fuel is a feature of on-site power generation. This article traces the history of "total energy" and describes how and where on-site generation of electricity makes sense.

Water And Energy, Frank Ellis

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

Energy self-sufficiency or independence from foreign oil imports depends critically on the yet undeveloped domestic fossil fuel resources, particularly for the production of heat, which can be utilized in the conventional and technically feasible thermal energy cycles of steam-electric generators and prime movers, which can easily be replicated. An integral facet of the complex domestic energy development undertaking is the availability of water that may be required to convert the vast domestic coal and oil shale resources into usable energy forms. An orderly utilization of water resources must receive attention if sufficient development of fossil- fuel conversion energy systems is …

Household Demand Responsiveness To Peak Use Pricing: Implications Drawn From Experimental Studies Of Consumer Demand Behavior Of Both Humans And Animals, Raymond C. Battalio, John H. Kagel

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

The authors approach the problem of demand responsiveness to peak use pricing from the perspective of experimental economists working in the area of consumer demand behavior. Results from experiments involving both human and laboratory animal consumers are presented suggesting that wide classes of house-_ hold economic activities will be quite responsive to changes in peak use pricing but that the demand for space heating and cooling will be highly inelastic without major changes in capital stocks. The reasons for these differences are discussed along with suggestions of low cost technologies for achieving greater price responsiveness in space heating and cooling …

Energy Conservation In Aeronautical Ground Testing, R. W. Hensel

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

Large aeronautical ground test facilities, particularly continuous flow wind tunnels and engine altitude test cells, are large users of electricity. Because of the correspondingly high absolute cost of energy, these facilities generally maintain continual programs to minimize both energy and power levels consistent with achievement of testing objectives. The recent sharp increases in kilowatt-hour costs (overall rates doubled within two years at the U. S. Air Force's Arnold Engineering Development Center, for example) have resulted in a proportional rise in efforts to effect further economies. The various methods available to reduce electricity costs fall in three categories: (1) methods related …
