Prospects For Conversion Of Solar Energy Into Electrical Power, William R. Cherry

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

In 1972, the Solar Energy Panel took a broad look at solar energy across the whole field to see just what could be done with this energy source. Maybe the era of acquiring energy without regard to cost and without regard to consequences of using it is beginning to come to a close and maybe we ought to start looking at the newer sources of energy, even though we need every bit of energy we can get from every source. I am not trying to say we don't need gas, oil, coal and nuclear energy. We are not going to …

Locating Nuclear Power Plants Underground, Frank M. Scott

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

This paper reviews some of the questions that have been asked by experts and others as to why nuclear power plants are not located or placed underground. While the safeguards and present designs make such installations unnecessary, there are some definite advantages that warrant the additional cost involved. First of all, such an arrangement does satisfy the psychological concern of a number of people and, in so doing, might gain the acceptance of the public so that such plants could be constructed in urban areas of load centers. The results of these studies are presented and some of the requirements …

Introduction -- Solar And Wind Energy, Jack L. Boone

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

In recent years the scientific community has begun to explore the many alternatives of using solar energy in terms of solar energy conversion schemes. These, in general, may be classified according to use. We can talk about solar to low-grade thermo residential heating and cooling applications. We can talk about solar to high-grade heat for such applications as steam powered generation and certain high-temperature conversion processes. We can talk about solar to electrical for either residential or for large power production installations; and we can talk about wind to electrical and this would, of course, come in both large and …

A Solar-Hydrogen Energy Conversion Scheme For Agricultural Use, R. L. Reisbig, Jack L. Boone, Gordon E. Weiss, Thomas Van Doren

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

A solar energy activated system is presented which can produce hydrogen and hydrogen-derived fuels (methanol) for use on farms. The device, named "solar-kine", also can produce fertilizer (anhydrous ammonia) as a byproduct of the hydrogen. A cost analysis shows that solar-kine may be mass-producible and sold to farmers for between $7,200 and $14,700. This is equivalent to giving the fanner energy at a price of $1.79 to $3.66 per million BTU's (in 1974 dollars). Presently (Spring, 1974) regular gasoline used in tractors at 43¢ per gallon, represents a cost to the farmer of $3.77 per million BTU's. As oil-based fuels …

Interfaces Of Steam Electric Power Plants With Aquatic Ecosystems, Gerald J. Lauer, William T. Waller, Guy R. Lanza

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

Growth and reproduction may be stimulated by increased temperature in the cooling system and thermal plume during seasons when ambient water temperature is less than optimum, but growth, reproduction and survival are reduced when the elevated temperatures become excessive. Some fish species congregate in the warm thermal plumes during cold seasons but are excluded from this living space by temperatures above their preference in the summer. However, the warm refuge provided by a thermal plume in cold seasons can be a death trap if a power plant shuts down suddenly and exposes the fish to cold shock exceeding their lower …

Multiregional Interactions Between Energy And Transportation, Karen R. Polenske

Applications

Because of the number and complexity of the issues that will determine the use of coal by the electric-generating plants, an important asset of policy makers will be the availability of a method of analysis that allows for quick studies of many different combinations of assumptions and policies. The present prototype study is designed to show how the multiregional input-output model can be used to investigate each different assumption and policy alternative. For this paper, the analysis has necessarily been restricted to two issues. First, the results of using regional rather than national technologies in the model are assessed. This …

Radiation Effects On Gaasp Light-Emitting Diodes And Schottky Barrier Field-Effect Transistors., Ranjeet Kumar Pancholy

Electrical and Computer Engineering ETDs

New processes have been developed for the fabrication of gallium­arsenide-phosphide light-emitting diodes and Schottky barrier field-effect transistors. The fabricated devices were characterized electrically and were tested in a radiation environment. Transient effects on p-n junction diodes due to high energy electron beams were examined and the permanent damage caused by high energy neutrons on both diodes and SBFETs were evaluated.

A unique open-tube diffusion process was developed for the fabrica­tion of the light-emitting diodes. A thick layer of GaAsP-oxide was grown over the epitaxial surface for surface passivation and to act as a diffusion mask against zinc diffusion into the …

Resonance Fluorescence And Resonance Raman Scattering: Lifetimes In Molecular Iodine, P. F. Williams, D. L. Rousseau, D. H. Dworetsky

P. F. (Paul Frazer) Williams Publications

We report a significantly shortened scattering lifetime in molecular iodine when the frequency of a single-mode 5145-Å incident laser is tuned away from resonance with a discrete transition. This observation of a shortened scattering time is indicative of what has been conventionally called a Raman process. Off-resonance lifetime measurements, as reported here, may provide a means of determining the relative contribution to the absorption line-width of homogeneous and inhomogeneous broadening.

A Comparison Of N-Path And Digital Filters For Band Pass Applications, Stephen Cooperman

Retrospective Theses and Dissertations

The classic problem of achieving high Q, band pass, inductorless filters has been traditionally attacked by applying active RC networks. This approach suffers from the faults of poor economy, lack of stability of performance with time and temperature, and high network performance sensitivity to component changes. The problem is reviewed from the aspect of applying techniques other than operational amplifier RC filters. The techniques presented are those of N-Path (switching) and Digital Filters. The underlying theory of both methods is explored and a design example for each of the techniques is presented. These designs are then compared on the basis …

A Comparative Analysis Of The Capabilities Of Three Stereo Radar Techniques When Operating In The Presence Of System Errors, George L. Bair

Masters Theses

"Three stereo radar techniques for producing stereo images from which topographic data and maps may be obtained are described and their performance in the presence of system errors is determined. The techniques are: an improved single flight technique which uses a combination of two antenna beam characteristics which permits terrain illumination from nearly the same aircraft position, a previously proposed single flight technique which uses two horizontal linear arrays generating vertical fan beams at different azimuth angles, and an existing two flight technique which uses a horizontal array generating a side-looking fan beam.

Error analyses are performed to determine the …

A Discrete Approach To Surface Interpolation, Jerry Lee Albert Sandvos

Masters Theses

"An equidistant spacing of two dimensional data points is a requirement of most automated analysis routines. In this thesis, a method of generating such equispaced data from randomly spaced data is developed and implemented by a set of computer routines. The method represents the study area as a two dimensional spatial array, in which each array cell represents the data value of a subarea of the study area. A routine sorts and places the data in the array. Missing values in the array are interpolated from nearest neighbors. Filtering is used to smooth errors and a contouring routine is used …

A Digital Simulation Of The Statistical Properties Of Ionospheric Scintillation, William Frederick Deckelman

Masters Theses

"This thesis shows that a bandlimited bivariate-normal time series is a useful model for the envelope of scintillating radio signals traversing the ionosphere. A software computer model is designed and its parameters varied to obtain good fits of the fade duration distribution of the time series generated by the model with that of an actual block of ionospheric scintillation data. The power spectrum of the actual time series corresponding to the in-phase and phase quadrature components of ionospheric scintillation is shown to lie between that of a first- and second-order Butterworth filter through comparison with model generated data"--Abstract, page ii.
