Creating The Electric Energy Economy, L. G. Hauser

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

My remarks will be directed to four points:

First, that energy is the life blood of our economy, and that its use or conservation is far from a simple matter of personal habits of waste or frugality. In other words, the vital role energy plays in the production of goods and services should be distinguished from its use in their consumption.

Second, that our excessive dependence on our two scarcest energy resources -- oil and natural gas -- is the core of the energy problem, both U.S. and worldwide.

Third, that limiting our time horizon to this winter, next summer, …

Energy And Transportation Policy, James S. Sagner

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

Energy shortages of recent years suggest a re-examination of national transportation policy. The lack of a coordinated approach to the solution of urban cogestion inhibits potential short-run responses to gasoline shortfalls. Longer-range policy, particularly in the context of severe financial constraints, must be carefully integrated with demonstrated patterns of urban travel and population and employment densities. Given these considerations, metropolitan areas now planning or constructing rapid rail facilities may be selecting inappropriate responses to the problem of urban access.

How Might Synthetic Fuels From Coal Affect Natural Resources And Environment?, H. J. Plass Jr.

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

Energy self-sufficiency for the U. S. requires substantially increased use of coal. Direct combustion of coal without adequate environmental controls, as would occur if coal were used as a fuel for homes and offices throughout the country, would result in severe air pollution problems„ Synthetic fuels from coal such as methane, low BTU gas, or hydrogen, when utilized by the homes and businesses as gas or as electricity from gas, will contribute a much smaller amount of air pollution. However, to make these synthetic fuels available, it is necessary to mine more coal than would have to be mined for …

Two-Dimensional Analysis Of The Coherent Instationary Motion Induced By An Obstacle, Using Electrochemical Methods, B. Py, C. Tournier

Symposia on Turbulence in Liquids

The non stationary flow induced by a cylinder with a square cross-section was studied on the cylinder's surface and in the wake with two different electrochemical probes. On the cylinder was mounted split rectangular electrodes with high enough aspect ratio so as to measure the chordwise component of the wall shear stress with its sign. The non-linear response of this transducer was studied. In the wake, the longitudinal component of the velocity was obtained with conical electroactive elementswhich are mainly sensitive to this component.

The fluctuating coherent components are separated from the aleatory part of the signal and then decomposited …

Subsolidus Equilibria And Metastable Phase Development In The System Zro₂-Al₂O₃-Sio₂, Charles Christopher Sorrell

Bachelors Theses

"Subsolidus equilibria in the low silica portion of the system ZrO₂-Al₂O₃-SiO₂ were studied by X-ray diffraction of quenched samples fired at 1300°, 1400°, and 1480°C. Samples prepared as powders from combinations of a-Al₂O₃, Al(OH)₃, silicic acid, ZrO₂, and kaolinite reacted very slowly at 1300° and 1400°C and the trends toward equilibria are not apparent. A mixture of zircon and Al(OH)₃ reacted slowly at 1480°C to form mullite and ZrO₂, indicating that the latter phases are the stable assemblage rather than zircon and alumina. A gel prepared from aluminum nitrate, zirconyl nitrate, and colloidal silica reacted at 1480°C to form alumina, …

Process Studies And Modeling Of Self-Cleaning Capacity Of Mountain Creeks For Recreation Planning And Management, Cheng-Lung Chen, Keith D. Davis

Reports

Reaeration process studies were conducted on a mountain creek and a large laboratory flume. The method of evaluating the dispersion coefficient, mean velocity, and reaeration coefficient for both creek and flume consisted of finding these values for a deoxygenated portion of the flow containing a conservative tracer (dye). The deoxygenated slug is measured as it moved downstream and the three values are best fit in the analytical solution of the longitudinal dispersion equation which dynamically describes the flow of the dispersing slug in the stream. The best fit was accomplished by using the method of least squares of the differences …

Nitrogen Transformation In Secondary Wastewater Treatment Plants, Mark Lee Morris

Retrospective Theses and Dissertations

Nitrogen is an essential nutrient for plant and animal life; however, its presence in concentrations exceeding assimilative capacities of receiving water bodies is undesirable. Therefore, the form and concentration of total nitrogen released in wastewater effluents is of great concern. During the course of this study, the nitrogen analysis was performed on the various unit processes of the Florida Technological University wastewater treatment plant. The average percent removal of nitrogen between plant influent and clarifier effluent was 30.5% during the month of August 1975. It is believed that the nitrogen removal is attributed to luxury uptake by the biomass through …

Stabilization System Environmental Disturbance Modeling And Analysis, Lawrence E. Sieb

Retrospective Theses and Dissertations

Systems that operate in airborne environments and rely on the resolution provided by optical sensors require a stabilization system to isolate the line-of-sight (LOS) from the operating environment. For systems employing television sensors, stabilization accuracy is of prime importance in maintaining sufficient picture resolution to allow target identification and recognition at maximum ranges. The development of system models that accurately predict stabilization performance is important both in design trade-offs and in the system design and testing [l]. Two basic concepts are available for achieving LOS stabilization; momentum stabilization which employs a spinning mass and rate stabilization which utilizes inertial rate …

Computer Aided Analysis Of Flat Plate Solar Collectors, Thomas L. Hartman

Retrospective Theses and Dissertations

A computer model of a flat plate solar collector has been devised. The model is able to simulate most common types of collectors, with up to three transparent covers of any material. Using primarily equations available from the literature the model calculates the transmission through the cover plates, the heat losses, and the useful heat gain. Derivation of all equations used are presented. A new method is presented for calculation of the mean plate temperature which differs from that commonly used in the literature. Experimental evidence is presented indicating that when transient effects are negligible the model is able to …

Test Methods For Evaluating Performance Of Solar Units, William Joseph Vitaliano

Retrospective Theses and Dissertations

This report is concerned with the performance of solar hot water units for laboratory and field use. A solar unit is defined as a system consisting of a collector, storage tank, piping system and controls. Older unites typically employ the thermosyphon principle (gravity) while more recent models use a water pump to circulate the water. Basically, the collector absorbs solar radiation and transfers thermal energy to the water flowing in the collector tubing. From the collector, the fluid is pumped to the storage tank at which point the hot water is available for usage. A literature search revealed that very …

High-Speed Bipolar Microprocessor Usage For Extracting A Constant Frequency Signal From A Pulse Stream, Lenard Jay Persin

Retrospective Theses and Dissertations

This report presents an initial design effort for a high-speed, constant Frequency data extractor, which can be used to identify and track a particular constant frequency signal in the presence of other signals. Several factors must be included in the design considerations. The detection and acquisition of the correct signal should be accomplished at high speed to remain as close as possible to real time. Once detection has occurred, the system should generate a track-predict gate signal that enables the input line only when the real input pulse is expected. If track is lost, which happens whenever the track-predict gate …

Integrated Numerical Simulation Of Drip Irrigation With Subsurface Drainage, James Ray Hoover

Electronic Theses and Dissertations

A numerical method and model were developed to simulate soil moisture during steady-state and transient flow toward a tile drain. Intermittent application of water by drip irrigation and rainfall were simulated by use of finite difference approximation equations. No known analytical solution for these flow situations exists because of the complex mathematics describing unsaturated flow in the soil. The computer model is based on the electrical resistance network analog. The explicit finite difference equations were solved by the successive over-relaxation method for steady-state flow and by iteration for transient soil moisture flow. The computer program for the model consists of …

Theoretical And Experimental Investigation Of A Viscous Ring Nutation Damper., Roy Alexander Campbell Iii

Masters Theses

"The dynamics of passive dampers applied to high s peed gyro systems is reviewed briefly and the partially filled viscous ring nutation damper is investigated. Particular attention is given to 1 the broken ring or nutation synchronous configuration where the fluid moves as a rigid slug and the damping is greatest. In this mode the damping is assumed to be viscous and expressions for a linear damping constant are presented. Data from an experimental, high-speed gyro is used to verify the theoretical analysis"-- Abstract, p. 1

A Strategic Planning Model For Implementing Community Development Block Grant Programs., John M. Lang

Masters Theses

"As problems of metropolitan areas have multiplied, the federal government has been drawn into an ever-increasing intimate funding association with city governments. Although federal funding for ii urban problems may have been considered a panacea by some, most local government agencies have now discovered that their problem has shifted in emphasis from where to find funds to that of meeting federal standards and requirements of application in order to get the funds.

The impact of federal programs on local government management is evident in the recently enacted federal Housing and Community Development Act of 1974. Title I of the act …

Dynamic Testing Of Anchors Buried In Dry Sand., Jim Lee Hillhouse

Masters Theses

"The dynamic pullout resistance of anchors was investigated through the use of model testing under controlled conditions. The soil used for the model tests was a dry sand compacted to a uniform relative density of approximately 92 percent. The dynamic loading of the anchor-soil system was applied by a mechanical device, which applied a specific amplitude and frequency of dynamic load to the anchor-soil system.

The dynamic testing of the anchors consisted of two phases. First, an initial static load was applied to the anchor. Second, a dynamic load was superimposed over the initial static load. The load applied to …
