Clustering Concepts In Automatic Pattern Recognition, Patricia J. Defilipps
Clustering Concepts In Automatic Pattern Recognition, Patricia J. Defilipps
Retrospective Theses and Dissertations
During the past decade and a half, there has been a considerable growth of interest in problems of pattern recognition. Contributions to the growth have been from many of the disciplines including statistics, control theory, operations research, biology, linguistics, and computer science. One of the basic approaches to pattern recognition is cluster analysis, in which various methodologies may be successfully employed. It is the purpose of this research report to investigate some of the basic clustering concepts in automatic pattern recognition.
Stormwater Runoff From Shopping Centers, Thomas P. Donigan
Stormwater Runoff From Shopping Centers, Thomas P. Donigan
Retrospective Theses and Dissertations
This is a brief investigation of stormwater runoff from a large shopping center located in Brevard County, Florida. Merritt Square Shopping Center has a parking area for 4,700 automobiles and is located on the shore of Newfound Harbor which is classified as recreation waters (Class III). A literature survey of runoff studies in other areas has been made for both "state of the art" and evaluation of findings. Water samples were initially collected from five locations. Review of the analysis of these samples indicated that while color and turbidity appeared to decrease linearly with time, organic and inorganic concentrations did …
The Effects Of Gap Stability On Entrance Ramp Merging, Lyn Evalyn Lane
The Effects Of Gap Stability On Entrance Ramp Merging, Lyn Evalyn Lane
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 …
Lake County, Florida Solid Waste Management Plan, Lawrence J. Morey
Lake County, Florida Solid Waste Management Plan, Lawrence J. Morey
Retrospective Theses and Dissertations
The history of solid waste management in Lake County, Florida is reviewed. The role of governmental agencies is mentioned. Local environmental characteristics and transportation systems are discussed. Existing collection and disposal practices are presented. A land use analysis of the unincorporated areas of the County is given. Projections of population and solid waste quantities are listed. Two computer models are presented. Their optimum solutions are analyzed in detail. The cost associated with implementing either plan is presented. A recommended plan is given based on a combination of transfer stations and sanitary landfills.
A Comparison Of Corrosion Rates Determined By Polarization Resistance Measurements For Zinc And Cadmium Metal Immersed In Nonstirred Aqueous Portland Cement Solution, William James Moore
A Comparison Of Corrosion Rates Determined By Polarization Resistance Measurements For Zinc And Cadmium Metal Immersed In Nonstirred Aqueous Portland Cement Solution, William James Moore
Retrospective Theses and Dissertations
The effect of nonstirred aqueous Portland cement solution on the corrosion rates of zinc and cadmium metal using Tafel extrapolation and linear polarization measurements has been investigated. Results indicate that for the corrosion systems under investigation, zinc metal has a higher corrosion potential and lower corrosion rate than cadmium metal.
Plating Wastewater Management, Earl Kenneth Ossorio
Plating Wastewater Management, Earl Kenneth Ossorio
Retrospective Theses and Dissertations
A study was made of existing methods of management, treatment and disposal of water and wastewater effluents at a large aerospace facility (Martin Marietta Aerospace) in Central Florida. Water consumption and handling were evaluated, with emphasis being placed on the handling of plating wastes, since they are the main contributor of industrial wastewater pollutants at the facility. The flow, storage, and treatment of the plating wastes were studied. Literature concerning plating wastes was surveyed to determine the latest "state of the art" on handling of plating pollutants. Then, the "state of the art" processes were compared with the existing processes …
Mixing Effects On Shallow Water Bodies, Kim Robin Powell
Mixing Effects On Shallow Water Bodies, Kim Robin Powell
Retrospective Theses and Dissertations
This report is intended to examine the ecological changes due to mixing in shallow water bodies. Physical, chemical, and biological changes are reported in literature. A literature search revealed the range of mixing nodes or processes. Assessment of ecological changes due to mixing by boating activities had been evaluated in a research project supported by the environmental Protection Agency and conducted at Florida Technological University. The examination of changes due to mechanical mixing on lake ecology simulated in fifty-five gallon drums indicated the sensitivity of such parameters as total Kjeldahl nitrogen, conductivity, pH, temperature, and dissolved oxygen. Problems of reproducibility …
Design And Calibration Of A Three Component, Single Element, Wind Tunnel Force Balance, Victor W. Tisdel
Design And Calibration Of A Three Component, Single Element, Wind Tunnel Force Balance, Victor W. Tisdel
Retrospective Theses and Dissertations
The purpose of this paper was to design a simplified wind tunnel force balance for use in elementary aerodynamics/wind tunnel laboratory courses. The applied loads and moments were determined to be as follows: The design lift force is ± 20 lbs, the design drag force is ± 10 pounds, the design pitching moment is ± 20 inch-pounds. The force balance output accuracy was arbitrarily set at ± 5% since this would be sufficient for preliminary student work. The results of this work are as follows: The force balance is fabricated from a single bar of 2024 aluminum, machines and bent …
An Application Of "Storm" Mathematical Modeling For Evaluation Of Nonpoint Source Water Pollution For A Nonurban Watershed, John T. Izzo
An Application Of "Storm" Mathematical Modeling For Evaluation Of Nonpoint Source Water Pollution For A Nonurban Watershed, John T. Izzo
Retrospective Theses and Dissertations
Today, the engineer is faced with the task of predicting and evaluating the extent of the Nonpoint Sources that pollute our waterways. A mathematical model may be an extremely useful tool in helping the engineer solve problems in the area of water resources. During the course of this investigation, a literature survey related to the Econlockhatchee River Basin and to the "STORM" mathematical modeling technique for runoff evaluation has been conducted. The latter part of this report deals with an application of the "STORM" mathematical model for predicting quantity and quality of surface runoff for the Econlockhatchee River Basin located …
