A Microprocessor Based-Instrument For Reconstructing A Coherent Optical Wavefront, Glenn Thomas Lommasson

Electrical and Computer Engineering ETDs

Characterizing a propagating laser's wavefront is a necessary procedure when evaluating the performance of coherent lasing systems. Measurement of this wavefront structure uncovers more useful information on the operation of lasing systems than does any other single diagnostic measurement, and is, therefore, critical when analyzing developmental lasers. There are currently several methods being used to measure this wavefront structure. One method that is noted for its operational simplicity measures the gradient of the wavefront as the wavefront is two-dimensionally scanned. An instrument that incorporates this methodology for scanning a wavefront's gradient field has been previously developed. Reconstructing the wavefront using …

Light Extinction In Polydisperse Particulate Systems, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

Analytic methods are developed for determining the attenuation characteristics of light beams propagating through ensembles of scattering particles including those with complex index of refraction. The methods are applicable to a wide range of practical particulate systems, and the results are expressed explicitly in terms of elementary functions. Propagation through fog and clouds is considered as an example, and it is found that absorption by the liquid lengths. water in such ensembles affects strongly the extinction for ir wave-lengths

The Energy Needs Of The Developing Countries, Vaman Rao

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

The energy needs of the developing countries are enormous. They will grow with the passage of time as the pace of economic development accelerates and those countries enter the industrial epoch. The sheer physical non-availability of coal and petroleum to most of them makes it obligatory to choose an unconventional resource as an energy-base. The nuclear fission is the only option now available which is feasible, less-expensive and plentiful. Solar and fusion may be the ultimate sources in the steady state, when appropriate technologies are developed.

A thorough cost assessment (including quantitative and qualitative factors) of alternate energy plans will aid both the selection of the most desirable alternate and the reduction of unforeseen costs and problems during and after construction .

Regulatory Effectiveness In The Electric Utility Industry: An Empirical Analysis, Michael A. Zimmer

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

An established result in the theory of the regulated firm is that an effective rate-of-return constraint induces the firm to employ larger proportions of capital inputs to noncapital inputs than would be the case in the absence of the regulatory constraint. This overcapitalization, often referred to as the Averch-Johnson effect, has been the subject of several recent empirical studies of the electric utility industry. The present study adds to this body of literature. It seeks to test for the effectiveness of utility regulation in the context of a cost minimization model which includes the allowed rate of return as an …
