Major research efforts have been directed in this area, primarily as a result of the Federal Water Pollution Control Act and Public law 92-500, the 1972 Amendments to the act. Yet, a need remains for more data in the field of stormwater management. Such needs include cost-performance data and planning methodologies to optimally select best management practices (BMP's). The research culminating in this report addresses these needs. A computer program, "MANAGE", has been written to generate cost/efficiency curves, and uses these curves to optimally select a combination of management practices. The program was written in FORTRAN language and was run on the IBM 360/370 computer system. It can analyze up to 3 management practices per subwatershed and up to 20 subwatersheds in a given watershed. The optimization routine of the program utilizes a piece-wise linear approximation method in its analysis.

Show moreUniversity of Central Florida College of Engineering Thesis; The quality movement has become popular among corporations big and small for one reason: empirical evidence suggests that quality and productivity (and hence profitability) are linked. Unfortunately, while many firms accept that quality and productivity go together, few actually track the gains associated with their quality improvement programs. Companies also tend to spend on quality improvement with no indication of estimation of the impact of funding on the targeted process. It would be of great value to know: (1) the impact of spending to enhance the product/process quality level, and (2) the point at which expenditures for quality improvement are not economical. This research involves modeling the quality level of a product composed of integrated components/processes and the costs associated with quality improvement. Presented in this research is a methodology for determining the point at which the target quality level is reached. This point signifies when future spending should be re-directed. The research defines this point as the "Crash Quality Point (CQP)." Cases of a single process level and double level three-stage process are modeled to conceptualize CQP. The finding from the output analysis reveal that the quality level approaches the target level at varying points in time. Any spending beyond this point does not have an impact on the quality level compared to the period prior to the Crash Quality Point. Spending past this point is futile and these funds could be spent on the quality improvement projects. The special case modeled also illustrates the use of this tool in the selection of processes for improvements based on the quality level of the process. This is an added advantage in scenarios where funds are limited and management is constrained to improve process quality with limited funds. Using a real world example validates the proposed CQP methodology. The results of the validation indicate that the model developed can assist managers in forecasting the budget requirements for quality spending based on the quality improvement goals. The tool also enables managers to estimate the point in time at which allocations of funds may be directed for process reengineering. The CQP method will enable quality improvement professionals to determine the economical viability and the limits in expenditures on quality improvement. It enables managers to evaluate spending alternatives and approximate when the point of diminishing return is reached.

Show moreFlorida Technological University College of Engineering Thesis; In 1975, C.S. Bauer completed a doctoral dissertation at the University of Florida which treated the Green Band Merging Control System on I-75 in Tampa, Florida. In this work, Bauer suggested the possibility for the use of computer graphics as a toll for analysis of the bands generated by the Green Band Control System Simulation developed in his dissertation. The use of computer generated movies of the bands displayed to ramp drivers by the system allows the comparison of various band control strategies without the need for field implementation and testing. With the goal of producing such films in mind, the research topic discussed in this paper was undertaken. The report introduces the reader to some of the basic aspects of computer graphics and presents specialized computer software and interface hardware for producing automated computer graphics movies from a Tektronix 4010 storage display. A brief discussion of the Tampa System and its associated simulation program is presented, and representative frames from the moves of the Tampa System produced in the research are discussed. Suggestions for additional work that could be undertaken in the research area conclude the report.

Show moreFlorida Technological University College of Engineering Thesis; This thesis, "System Safety in Rail Transportation" is addressed to an individual having a basic technical background but little or no experience in this field. The thesis discusses the need for and the benefits to be obtained by using system safety techniques and principles in the railroad industry. Examples of typical railroad accidents are reviewed, and it is pointed out that analysis of the hazards in the railroad industry prior to the accidents would have identified problems which eventually resulted in the accidents. The system safety approach, which was developed for use in the aerospace and aviation fields, has proved to be extremely effective and is now being adapted to many other areas. The surface modes of transportation have the greatest need for these techniques. The techniques covered in this thesis include Hazard Analysis, Fault or Logic Tree Analysis, Failure Modes and Effects Analysis, and Probabilistic Cost Analysis. The thesis also describes a hypothetical model for organizing and implementing system safety approaches in an existing railroad company.

Vertical sections of the sediment were taken at depths of .1, .5 , 1, 2, 3, 4, 5, 6, 10 and l5 centimeters below the surface of the sediment-water interface. Total Phosphorus analysis was done on each section. The profile presented was then evaluated and was found that the profiles best fit the equation Y = X/ A + BX, where Y is the Phosphorus Concentration in ppm. and X is the sediment depth in cm. Correlation between the trophic state and the profiles characteristics are presented. A hypothesis as to how, the sediment profile changes as the lake experiences increased Phosphorus loading is presented, and is used to evaluate the lake studied. This discussion expresses phosphorus dynamics within the sediments in terms of adsorption, chemical changes, biological activity, and molecular and eddy diffusion.

Show moreFlorida Technological University College of Engineering Thesis; The United States' energy crisis, which has received so much publicity lately , has focused national attention on how we are to meet our energy demands. Proposed energy sources include conventional nuclear power plants, breeder reactor and fusion reactor plants, coal gasification, liquid hydrogen, solar energy, and geothermal energy. All of these except conventional fission plants are still on the drawing board or in the experimental laboratory, and are described briefly. Government and industry are betting heavily on conventional nuclear power plants. ($40 billion already spent by private utilities for 30 operating plants, 60 under construction, and 75 on order.) A. few unpublicized accidents and more and more complex instrumentation in nuclear power plant control rooms has pointed to a desperate need for more effective ways of training individuals to safely operate these plants. Recognizing this need, General Electric Company designed and built a very realistic computer-driven simulator of a plant control room. The physical enclosures and instrumentation duplicates the Dresden II control room in every way, and response to operator manipulation of controls duplicates that of a real plant. The bulk of this paper describes the simulator and its development. The last section raises questions concerning hazards of continued growth of nuclear power and presents some alternatives.

The simulation model, which is based on functional activities, emphasizes the interdependent consequences of decisions and actions created through management planning, analysis, and control of training programs. A simulation experiment was conducted using a test situation description (scenario) to reflect the impact of management decisions and actions on the resulting allocation of resources and timeliness of training program activities. Conclusions are drawn regarding the utility and implications of the system dynamics model as a management tool with which to improve training. Recommendations are made regarding future experimentation and analysis which is required for sufficient development of a useful management tool.

Show moreFlorida Technological University College of Engineering Thesis; The ever increasing traffic congestion being experienced on urban freeways has caused attention to be focused on methods for improving traffic operations on these facilities. The reduction or elimination of freeway congestion can be handled in two basic ways: 1) by increasing the freeway's capacity defined as the number of vehicles per unit time that can pass a given point in one lane of the freeway multiplied by the number of lanes on the freeway, or 2) by decreasing the traffic loads imposed on these freeways. Monumental costs and adverse public relations are involved in the construction of either new freeways or additional lanes in urban areas to increase freeway capacity. Due to these factors, the move in recent years has been toward decreasing traffic loads to accomplish the goals of reduction or elimination of freeway congestion. In an effort to combat the freeway congestion, traffic researchers have devoted much time and effort to the theoretical and practical aspects of systems in which controlled access is utilized to prevent or reduce congestion caused by traffic demands in excess of freeway operational capacity. Such systems perform the function of 'freeway surveillance and control'. An important aspect of these systems is the control mechanism used for the regulation of the ramp traffic to the freeway. This topic of ramp metering is the subject of this report.

The objective of this research was to investigate the feasibility of using data generated by the accelerated flight tests as a basis for forecasting the logistical field requirements. The data used in the study were obtained from the U.S. Army Aviation Board, Fort Rucker, Alabama, where performance tests are conducted on all new aircraft to determine their suitability for Army use. It was statistically shown that the use of these data could provide more realistic logistical forecasts earlier in the introductory phase of the aircraft. This concept would increase the operational availability of the aircraft and reduce the cost of maintaining the aircraft during its introductory phase.

Show moreUniversity of Central Florida College of Engineering Thesis; A vast amount of work has been published regarding grayscale processing of digital images. Although some of this work has been adapted for color images, many of the resulting algorithms neglect the correlation that exists between the individual RGB color components. Consequently, they introduce color artifacts. Attempts have been made to decouple the RGB components through color space transformations that isolate the luminance from the chromatic information. Color image enhancement is then considered a two step process, where the luminance and the chromatic components are processed independently. However, the RGB color space only has a finite number of available colors, which limits the attainable chromatic values for any given luminance level. This recoupling of the chromatic and luminance components constrains the independent processing of these two components. This thesis investigates this coupling and how it effects a number of color image processing algorithms. Specifically, new algorithms for color histogram equalization, automatic white balance and color filtering are presented using the C-Y (color difference) color model. Coupling the chromatic components to the luminance produces improved white balanced results and enhances the ability of histogram equalization to increase saturation contrast. Furthermore, several adaptive filters are implemented using the C-Y color space. Because this color model closely matches the human concept of color, the noise is filtered from color components that closely match the perceptually significant quantities. This improves the results for these adaptive filters, but also requires special attention when filtering the hue component. Improper filtering of the hue component can often lead to color artifacts.

Show moreUniversity of Central Florida College of Engineering Thesis; Traditionally, batch settling tests have been employed to determine the values of the settling parameters V0 and K of the Vesilind equation which represents activated sludge settling velocity as a function of solids concentration. It remains unresolved how closely batch settling tests describe settling in full-scale clarifiers. An experimental procedure was developed to determine scale factors between batch settling and full-scale solids flux curves. An experimental protocol was determined for full-scale clarifier operation, including specific criteria of necessary instrumentation and operational flexibility. Several graphical techniques were evaluated and a procedure was selected to determine a scale factor between batch and full-scale settling. The specified procedure requires determination of underflow velocity and concentration. The scale factor was approximately 0.84 as applied to the limiting flux, thus clarifiers designed from batch settling tests would be underdesigned. In addition, a methodology was developed to account for batch flux curve variability in the form of a safety factor. Finally, a design procedure was recommended to calculate clarifier area based on the scale factor determined from the batch and full-scale experiments.

Show moreFlorida Technological University College of Engineering Thesis; Although a Transient Simulation Program (TRNSYS) has become a widely used model for simulating a solar energy system, there has not been extensive work done in validating this model with actual data. The approach used to validate this model consisted of a modular buildup of components with validation for each module. Extreme care was taken in choosing the necessary parameters to model each component. Where parameters were not given, they were either derived or reasonable values were selected based upon general conditions prevailing in Central Florida or conditions which are generally true for certain solar hot water systems. The intent of this approach was to avoid forcing the model to fit experimental data. Such forcing can cause present results to correlate favorably, but gives no assurances for model performance in future simulations which may be made for varying conditions or completely different systems.

Recession of the tip results in an increased exit flow area which reduces the total pressure of the gas in the blast tube. Measurement of the blast tube pressure and gas generator (chamber) pressure will produce an effective measurement of the nose tip recession as long as choked flow (i.e., sonic velocity) is maintained in both the tip exit area and the gas' generator throat area. Governing flow equations documented in the literature are developed for double choked flow. Hypersonic wind tunnel test data are presented to verify the developed flow equations and to identify the mass flow ratios necessary to sustain double choked flow.
