A Study Of Assimilative Capacities For Receiving Streams, Hadi. Elmi

Retrospective Theses and Dissertations

Literature reviews on various stream processes which contribute to reoxygenation and deoxygenation was presented. These processes include atmospheric reaeration, photosynthesis-respiration, biochemical oxygen consumption, and benthic demand. Measuring these parameters in a selected stream is a complex and costly operation. On the other hand, prediction models developed are specific to particular location and environmental conditions and can only be applied to similar situations. Computer models such as "RIVER" are available and could be used to predict dissolved oxygen concentrations along a waterway for a specified set of stream conditions. The model "RIVER" was calibrated by using the existing conditions of flow …

A Status Report On Solar Energy Utilization In The State Of Florida, Henry Michael Armstrong

Retrospective Theses and Dissertations

The current energy crisis has pointed out the need for alternative, non-depletable sources of power. Solar energy would appear to be a likely source of such power for the state of Florida where the average home receives enough of this energy to supply all of its heating and cooling needs during the course of the year. Energy consumption profiles for Florida reveal that almost one-quarter of all energy is consumed within the residential-commercial section for basic heating and cooling. Additionally, the state is, essentially, totally dependent on petroleum and natural gas for its energy supply. Solar energy has been used …

Feasibility Study Of The Utilization Of Solar Energy For Large Scale Power Production In The State Of Florida, Michael Propen

Retrospective Theses and Dissertations

The objective of this paper is to investigate the feasibility of large scale electric power generation in the state of Florida by means of solar conversion. Such systems convert solar radiation directly to electricity or to thermal energy and subsequently to electricity. With the latter method, solar energy is initially collected and converted to heat at high temperature through a working fluid. The heat is then used to power conventional heat engine generator systems. Several methods have been proposed for converting sunlight to useful work. The most promising of these will be examined from a technological and economic viewpoint.

Retrospective Theses and Dissertations

This report analyzes freeway data from a moving merge control system in Tampa, Florida. The distribution of velocity at sensors in the roadway is plotted and compared to a normal distribution. The size of the gaps at each sensor are computed and compared to those at a sensor downstream. The distributions of the change in gap size are plotted for all gaps and then for gaps between the same pairs of vehicles, to determine the effects of prohibiting lane changing. The expected time of arrival of the gaps at a point downstream are computed, compared to the actual time of …

Analysis Of Unstable-Resonator And Optical-Train Laser Alignment Systems By The Use Of Matrix Methods Of Gaussian Optics, Frederick H. White

Retrospective Theses and Dissertations

A high-power gas dynamic-laser example system is described, and its optical elements are represented in the ABCD-matrix formalism of Gaussian optics. Propagation of Gaussian beams, image formation, focusing, and steering by transverse refractive-index gradients are modeled with the ABCD matrix technique. The effects of small translations and rotations of optical elements are represented as matrices and vectors in the ABCD-matrix formalism, and are analyzed as component misalignments with single and multiple beam reflections. Example calculations show that alignment beams making multiple round trips inside an unstable resonator can easily provide satisfactory resonator alignment and designation of the aim point of …

Suspended Solids And Deep Well Injection Systems, D. Robert Smedley

Retrospective Theses and Dissertations

A test method and the associated equipment have been developed to investigate the effect of suspended solids on the flow of fluid into a deep injection well system. Preliminary testing indicates that the equipment and test method can be used to determine the permeability of rock samples with a high degree of accuracy. Additionally this equipment can be used in a testing program which will eventually lead to the development of guidelines for the degree of pre-injection treatment required for suspended solids so that the operational life of the well is not impaired.

Stormwater Management For Urban Areas, Gerald L. Chancellor

Retrospective Theses and Dissertations

Stormwater management in urban areas is a major concern today. The problem of disposing of this stormwater runoff in a satisfactory manner is very difficult indeed. Both the quantity and quality aspects of the runoff must be dealt with to obtain a solution of this problem. The water quality of the runoff can vary depending upon the different land uses of the drainage basin. The quantity of the stormwater runoff also depends upon the land uses, the rainfall intensity and duration of the storm. The traditional methods available for determining the quantity of the stormwater runoff are numerous. These traditional …
