An Experimental Study Of The Reactions Of Excited Neon Atoms In Pure Afterglow Plasmas Using Resonance Absorption Spectrometry, R. A. Sierra, J. Beverley Clark, A. J. Cunningham

Materials Science and Engineering Faculty Research & Creative Works

Resonance absorption spectrometry has been applied in a room temperature study of the reactions of excited neon atoms in pure afterglow plasmas. The pressure range 10-500 Torr was investigated. Lorentz broadened linewidths calculated using a simple classical interruption theory allowed fractional absorption signals as large as 98% to be analyzed and absolute excited-state concentrations to be determined. The first absorption studies of the decay of 1P1 excited atoms in neon afterglows are reported. Analysis of the decay profiles of the 3P2, 3P0 and 1P1 excited states allowed quenching rate coefficients for each state to be determined and the role of …

Reliability Analysis Of Emergency Telephone System Models, Thomas J. Hobbs

Retrospective Theses and Dissertations

Several alternate systems for use in implementing the 911 emergency system in Orange County, Florida were investigated. The proposed systems were compared with the already existing systems on the basis of reliability, response time, and cost. System reliability was the prime consideration of the study. Flow charts of each system were formulated in order to determine the functions required of equipment and humans. The reliability was then determined by examining the difficulty of the tasks that each was required to perform. Reliability models of the present and proposed systems were constructed. By examining these models and comparing the reliabilities, response …

Ethylene Process Optimization. Constraint Relaxation And Bounds Adjustment, Kenneth R. Jinkerson, James L. Gaddy

Chemical and Biochemical Engineering Faculty Research & Creative Works

Heavily constrained, mixed integer optimization problems present a difficult test for optimization algorithms. This paper examines optimization of the ethylene process (from ethane) using a flowsheet simulation model and the adaptive random search. Optimization resulted in an improvement in annual earnings of $1.15 MM over the usual ethylene process design. This process has both continuous and discrete variables and has sensitive implicit constraints in the pyrolysis furnace. The search efficiency was found to be improved by relaxing these constraints early in the search and then restoring the constraints as the optimum is approached. The search efficiency was also improved by …

Retrospective Theses and Dissertations

The physical properties and subjective characteristics of sound and several special methods of measuring sound levels are discussed in order to provide a basic understanding of sound in general and noise in particular. The Federal Aviation Administration's regulation, FAR36, which stipulates the allowable perceived noise levels produced by commercial jet aircraft, is examined in detail. The principle of jet propulsion, the basic components of turbojet and turbofan engines, the theory of aerodynamic sound and the origin of the perceived noise decibel (which is the basic unit for measuring aircraft noise) are presented to provide an understanding of the fundamentals of …

Noise Pollution In The Industrial Arts Laboratory, James A. Sundell

Graduate Research Papers

Industrial arts instructors have always recognized the need for a pleasant and safe environment in their laboratories. Advancements in technology have increased noise pollution in this environment.

Sounds have a useful and important place in the laboratory; also, they can have adverse effects. The instructor can tell immediately if a machine is not performing correctly by the sound it emits, while the operation of the same machine can distort an important verbal communication. Excessive decibel levels may be generated at different times threatening the psychological and physiological well-being of teachers and students (Brown, 1979; Hicks, 1973; Swogger, 1973).

Noise Performance Of The Klapper-Kratt Low Delay Fm Detector, Allan Brown Tarbell

Dissertations

In this dissertation the dual differentiator version of the Klapper-Kratt FM detector family is investigated with additive Gaussian noise. Prior analysis of this new detector family has been limited to the noiseless case.

The investigation was conducted both analytically and experimentally. First, the dual differentiator version of the Klapper-Kratt detector was mathematically analyzed, assuming an unmodulated carrier plus additive Gaussian noise. This analysis was verified by assembling the detector and measuring its performance in the laboratory.

It was discovered that the Klapper-Kratt detector without limiter performs identically to the conventional limiter discriminator in the linear improvement region. When compared to …

A New Mathematical Model For Nephron Macromolecular Selectivity, John Anthony Domiter

Theses

A mathematical model describing the displayed selectivity of the kidney nephron to macromolecules of varying particle size is presented. Diffusion and electrical forces are considered to be the sole mechanisms of transfer. The mass transfer principles responsible for selectivity are considered to occur within the capillary structure, and not within the membrane wall. A charge is assumed to be characteristic of the macromolecule and the membrane wall. Models describing both charged and uncharged solutes are developed.

A non-linear least squares technique, developed by Marquardt, is used to curve fit the derived functions to data relating fractional clearances of dextran and …

A Feasibility Analysis Of A Directly Sun-Pumped Carbon Dioxide Laser In Space, Seiichi Morimoto

Dissertations and Theses

The possibility of using sunlight to pump a CW carbon dioxide laser has been analyzed. Such a laser could be of interest for such applications as space communication and power transmission. In order to optically pump CO₂ using sunlight, the intense vibrational-rotational absorption bands of CO₂ in the 4.3 micron spectral region would have to be utilized. The total pumping power from sunlight can be calculated from the known data of the solar spectral irradiance outside the atmosphere and the infrared absorption by carbon dioxide at 4.3 microns. The pumping power is proportional to the collector area of …

The Effects Of Artificial Destratification On Water Quality In Hyrum Reservoir, John W. Gill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Hyrum Reservoir, Utah, was studied for one year during an artificial destratification project. Previously Drury et al. (1975) had studied Hyrum Reservoir for one year of stratified and one year of destratified conditions. The redistribution of dissolved oxygen to the hypolimnion significantly changed conditions for chemical and biological activities in the lower depths of the reservoir. The Aphanizomenon bloom increased with each year of destratification. The reservoir was changed by destratification so as to be suitable habitat for trout on a year round basis. Aerobic conditions prevented iron from being released from the sediment into the aqueous phase. In summary …
