Economic Aspects Of Imposed Air Standards, John H. Hoag, J. David Reed
Economic Aspects Of Imposed Air Standards, John H. Hoag, J. David Reed
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Due to concern for the state of the environment, the federal government passed laws forcing industry to accomodate the wishes of environmentalists. In particular the Clean Air Standards Act imposed a measure of air pollution and dictated an upper bound on the amount of allowable air pollution in terms of this standard. This paper attempts to investigate the impact of such a law in the context of a two firm world. In the model each firm produces output and pollution so as to maximize profit. The pollution of all firms together is the variable which comes under constraint of the …
Devonianohio Shale Productive Potential, W. M. Hennington
Devonianohio Shale Productive Potential, W. M. Hennington
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The Devonian - Ohio Shale has tremendous producible hydrocarbon reserves that can currently be located and produced by slightly modified exploration, development and bore hole stimulation techniques. Drill site selection utilizing depositional structural relationships to locate the natural compaction fracture reservoir could improve productivity. The Devonian - Ohio Shale is significantly different from the Western Oil Shale since it has primary oil and gas production. This hydrocarbon source could substantially contribute to short term energy needs and the Self Help Energy Program.
Geophysical Approaches To Coal Exploration, Gerald B. Rupert
Geophysical Approaches To Coal Exploration, Gerald B. Rupert
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The exploration for minerals by geophysical means has been confined largely to the search for hydrocarbons and metallics while applications to coal exploration are somewhat limited. However, the surface reflection seismic technique has been successfully applied not only to delineating coal deposits but also as a tool in mine exploitation. Furthermore, channel waves generated underground have demonstrated potential in detecting the presence of faults in advance of the coal face and Vibroisis* experiments have been conducted whereby abandoned underground workings have been detected by surface seismic arrays. Examples of all of the preceeding are presented and discussed.
The Forgotten Fundamentals Of The Energy Crisis, Albert A. Bartlett
The Forgotten Fundamentals Of The Energy Crisis, Albert A. Bartlett
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Papers at an energy conference may tend to deal with details. The details are important, but only if they relate to the national or global picture. We know that an energy crisis has motivated us to look at all manner of detail in regard to our own particular uses of energy. We hear political leaders of the United States speaking of "energy self-sufficiency" and of "Project Independence". We have the vague feeling that arctic oil from Alaska will relieve the energy crisis, and we are told that the United States is in good shape in the long run because of …

Seismic Reflection Profiling -- In Mining And Civil Engineering, John B. Farr
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
A new high resolution seismic reflection technique with an accuracy of a few feet has been developed for shallow mining and civil engineering applications. Very small dynamite charges generate high frequency seismic waves with insignificant surface effects. Special detectors in shallow boreholes are used in conjunction with a high sample rate digital recorder to produce seismic cross sections having frequencies as high as 800 Hz and resolutions 10 times better than heretofore obtained using conventional oil exploration techniques.
Remote Sensing As A Tool In Assessing The Impact Of Topographical Alterations On The Microclimate, R. A. Sutherland, J. F. Bartholic
Remote Sensing As A Tool In Assessing The Impact Of Topographical Alterations On The Microclimate, R. A. Sutherland, J. F. Bartholic
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Results and analyses of remotely sensed data taken from a NASA aircraft are reported. The study uses continuous data taken in the 8-14ym region of the infrared spectrum which is directly related to surface temperature. The analysis is concentrated on the micrometeorological effects of lakes and hills during near freezing conditions. The impetus for the study is an economic one since proper selection of a site for certain freeze susceptible crops, such as citrus, can result in huge savings of energy and resources.

Economic Analysis Of Wind Generation And Energy Storage For Electric Utility Systems, B. W. Jones, P. M. Moretti
Economic Analysis Of Wind Generation And Energy Storage For Electric Utility Systems, B. W. Jones, P. M. Moretti
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
If wind generators are being evaluated as part of a larger electric utility generation system, the economic analysis should consider all of their effects upon the make-up and operation of the rest of the system. The introduction of wind generators changes the characteristics of the effective load seen by the rest of the system and consequently shifts the optimal mix of base, swinging, and peaking capacity and their operation. Storage systems used in conjunction with wind generators must also be evaluated. The storage can also be evaluated by determining its effect upon load characteristics. It is shown that the storage …

"Home Winterization For Poor Elderly" -- A Model Of Value Clarification In The Energy Crisis, Clayton L. Smith
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The main intention of this paper will be to demonstrate a practical and proven model for helping those who suffer because of the energy crisis now. It will illustrate with the aid of audio—visuals what is being done for the poor elderly in this area to help them practice energy conservation. Last year, for example, nearly three hundred U.M.R. students directed by a V.I.S.T.A. worker (Volunteers in Service To America) winterized nearly fifty homes. Engineering students were able to demonstrate their skills and at the same experience an intergenerational ministry.
The poor elderly are those persons in our society today …

Acoustic Emission, Fatigue, And Crack Propagation, Theodore Hopwood Ii
Acoustic Emission, Fatigue, And Crack Propagation, Theodore Hopwood Ii
Kentucky Transportation Center Research Report
Acoustic emission was used in conjunction with tensile tests to evaluate the condition of structural steel specimens subject to various tensile fatigue lives. The results indicate that the acoustic emissions detected were the result of plastic deformation. There was no apparent relationship between fatigue history of the steel specimens and the amount of plastic deformation they can accommodate.
Further tests revealed that acoustic emission has the physical capability of detecting cracks on large structural steel members. This may prove beneficial for the comprehensive testing of steel bridges.
Analytic Modeling Of Gain‐Switched Lasers. I. Laser Oscillators, Lee W. Casperson
Analytic Modeling Of Gain‐Switched Lasers. I. Laser Oscillators, Lee W. Casperson
Electrical and Computer Engineering Faculty Publications and Presentations
Detailed mathematical models are derived for the evolution of light pulses in gain‐switched laser oscillators. Unlike previous instantaneous‐switching models, arbitrary pump and spontaneous relaxation rates are considered. Explicit expressions are obtained for the gain and pulse characteristics in several practical situations, and both homogeneous and inhomogeneous limits are considered. By proper adjustment of the laser pump any output‐pulse shape can be obtained. The results are especially relevant for recent short‐pulse ultraviolet lasers and also for more conventional devices such as TEA CO₂ lasers.

Ellipsometer Nulling: Convergence And Speed, Rasheed M.A. Azzam, D. L. Confer, N. M. Bashara
Electrical Engineering Faculty Publications
The process of nulling in ellipsometry is studied by a graphical presentation using the trajectories of two significant polarization states in the complex plane, XPC and XSA. These states are determined by (1) the polarizer and compensator (XPC) and (2) the specimen and the analyzer (XSA) in the polarizer-compensator-specimen-analyzer ellipsometer arrangement. As the azimuth angles of the ellipsometer elements are varied, XPC and XSA move closer to one another in a stepwise fashion until they coincide when a null is reached. Thus, at null, the polarization states are matched, and XPC = XSA. For …

Evaluation Of Upwelling Infrared Radiance In A Nonhomogeneous Nonequilibrium Atmosphere, Sundaresa Venkata Subramanian
Mechanical & Aerospace Engineering Theses & Dissertations
The primary purpose of this study was to investigate the influence of vibrational nonequilibrium upon upwelling infrared radiance from the earth's atmosphere. Basic equations are presented for calculating the atmospheric transmittance, heating rates, and equilibrium and nonequilibrium upwelling radiances. By employing the Lorentz line-by-line model for spectral absorption, heating rates and upwelling radiances were calculated for equilibrium as well ·as nonequilibrium conditions in the spectral range of 4.6 μ CO and 3.3 μ 'CH4 bands. For the spectral range of CO fundamental band, the influence of different 1~arameters on the upwelling radiance was also investigated. The results indicate that …

Analytic Modeling Of Gain‐Switched Lasers. Ii. Laser Amplifiers, Lee W. Casperson
Electrical and Computer Engineering Faculty Publications and Presentations
The pulse transfer characteristics of gain‐switched laser amplifiers are investigated analytically. New closed‐form solutions have been obtained including arbitrary space‐ and time‐dependent pump distributions. The general results are specialzied to the important cases of uniform and traveling‐wave excitation. Input‐pulse shapes considered include step functions, practial oscillator output pulses, and also the inherent spontaneous‐emission noise. The results lead to improved models for pulse amplifiers and mirrorless traveling‐wave lasers. By proper choice of pump characteristics arbitrary output‐pulse waveforms can be synthesized.

Non-Linear Finite Element Analysis Of Light Gage Steel Shear Diaphragms, Erdal Atrek, Arthur H. Nilson
CCFSS Library (1939 - present)
SUMMARY Shear diaphragm action of properly designed light gage steel panels used for floors, roofs, and walls in steel buildings increase the stiffness and strength of such buildings. Considerable savings in weight and cost can be realized if full account of this action is taken in design. To make good use of the diaphragm action, detailed knowledge on diaphragm response to loading is essential. An efficient computer program has been prepared to analyze light gage steel shear diaphragm behavior in the linear and nonlinear ranges of response, up to collapse. The program uses figinite element concepts for analysis, and has …
