A One Step Collision Detection Method For Computer Graphics Programs, Gregory T. Eichner

Retrospective Theses and Dissertations

The topic of this thesis is a collection detection algorithm for use in computer programs dealing in three dimensional graphics. Collision detection is usually accomplished by breaking the movement into small steps and checking if a collision has occurred at each of these discrete steps. This method is a very time-intensive way to detect for collisions and therefore, inefficient for a system which typically moves in large increments. For this kind of system, a method could be developed which checks once for collisions without dividing the move into multiple small increments. The subject of this paper is an algorithm, developed …

Simulating The Thermal Behavior An Earth-Stationed Satellite Terminal, Anthony M. Jacobi

Retrospective Theses and Dissertations

Lumped parameter modeling using finite differencing, form the basis for a C language simulation of a thermal system. The study of the earth-stationed satellite terminal includes an introduction to the system, derivation of the governing equation, development of a simulation, and a comparison of the results to empirical data.

The analysis is undertaken with emphasis on the worst-case thermal environment, and with determination of the cooling loads and transient response as primary goals. Comparing the predicted cooling loads to empirical data, and previous analyses, indicates an accurate simulation has been constructed. The computer models are offered as an alternative method …

The Effects Of Trace Organic Carbon On Aluminum Solubility, Fernand J. Tiblier

Retrospective Theses and Dissertations

The Relative Efficiency Of Computer Controlled, Adaptive And Learner Centered Training On Transfer Of Training In A Computer Simulation Task, Lois-Ann Kuntz

Retrospective Theses and Dissertations

There is a need for effective cost efficient training programs. Individual differences have been shown to be the most important variable in many training programs and they should be paid special attention in the design of training programs. Compared in this experiment is computer-controlled (lockstep) training, adaptive training, and learner-centered training. Learner-centered and adaptive training are geared to the individual. Instead of lockstep training, learner-centered training allows the trainee to determine the amount or sequence of training at different levels of proficiency. Adaptive training is training based on the participant's performance. As the participant's performance improves he or she is …

Human And Natural Causes Of Marine Turtle Clutch And Hatchling Mortality And Their Relationship To Hatchling Production On An Important Florida Nesting Beach, Blair E. Witherington

Retrospective Theses and Dissertations

Populations of Western Atlantic loggerheads (Caretta caretta) and Florida green turtles (Chelonia mydas) have been in historical decline. The identification and protection of beaches that are major producers of loggerhead and green turtle hatchlings are vital to the preservation of these species.

A study assessing loggerhead and green turtle hatchling production was initiated at a 21 km stretch of beach in south Brevard County, Florida (Melbourne Beach) during the 1985 nesting season. Nesting densities were assessed from a season-long (10 May – 12 September) census in which every nest was counted and identified to species. An analysis of average reproductive …

Florida Macrolichens As Potential Bioindicators Of Environmental Quality: A Baseline Study, Harry V. Neal

Retrospective Theses and Dissertations

Lichens have been used extensively and with considerable success as bioindicators of atmospheric pollution in North America and Europe for more than thirty years. Little research has followed in tropical and subtropical regions where population growth is rapid and environmental pressures unprecedented. However, taxa used as bioindicators in other studies and/or taxa having this potential, occur naturally in Central Florida. A new potential major source of pollution, the coal-fired Curtis H. Stanton Energy Center, is about to begin operation providing the opportunity to determine the extent of impact. Therefore, lichen monitoring sites have been established and the collection of baseline …

The Effect Of Sewage Effluent Removal On The Water Quality Of Lake Howell, Florida, Patricia L. Smith

Retrospective Theses and Dissertations

In April, 1983, sewage effluent discharge from the Maitland and Winter Park sewage treatment plants was diverted from Lake Howell to the Iron Bridge Regional Sewage Treatment Plant. The sewage treatment plants of the cities of Winter Park and Maitland had been discharging into Lake Howell since 1927 and 1962, respectively. These point sources had contributed 95% of the total phosphorus and 69% of the total nitrogen budgets for Lake Howell. Physico-chemical parameters were monitored monthly for two years chemical parameters were monitored monthly for two years from January, 1983 through December, 1984. Annual mean values fro chlorophyll_a, …

Park Equus Tourist Study, Ady Milman

Dick Pope Sr. Institute Publications

Tourism is the largest industry in the state of Florida and especially large in Central Florida. In 1985, close to 30 million domestic and international tourists visited the state. These visitors purchased goods and services worth $19 billion. The Florida Division of Tourism estimated that in 1985, Central Florida was one of the most popular destinations in the state, hosting 23% of auto visitors arrivals and 19% of air visitors arrivals. Central Florida attractions have always been very popular: In 1985, Walt Disney World's Magic Kingdom and EPCOT Center accounted for over 50% of Florida's air and auto attraction visitors. …

Direct Digital Control Of A Liquid Level/Temperature Control Unit, Pedro J. Claudio

Retrospective Theses and Dissertations

A direct digital control algorithm was implemented on a liquid level and temperature control unit. Two control schemes were implemented on the system and the results were compared against a fourth order Runge-Kutta solution.

Both control schemes involved proportional feedback with dynamic adjustment of the operating point. It was found that the control scheme that contained a feedforward component which dealt with the inlet water temperature had a superior dynamic response to setpoint changes. Steady state offsets in both control schemes were attributable to model parameter estimation errors. Differences between the actual and predicted system dynamic response were also attributable …

Editor Design In The Context Of Control System Simulation, Leon Fadden

Retrospective Theses and Dissertations

Advances in microcomputer display devices and support software during the past decade have made the microcomputer an increasingly popular vehicle for technical education. This is especially apparent in the area of simulation. The pedagog can provide the student of control theory not merely with the block diagrams and differential algebra but with high resolution color graphic animations supported by mathematical models whose parameters are easily changed by some editor facility. This mode of control system design and behavior study is both faster and more enjoyable for the student, providing greater continuity, concentration, and learning efficiency.

This paper describes the simulation …

The Effect Of Food On Reproduction In The Sailfin Molly, Poecilia Iatipinna (Poeciliidae, Rebecca B. Smith

Retrospective Theses and Dissertations

Sailfin molly populations often experience a midsummer slump in reproduction, and it has been suggested that this slump is caused by food shortage. A food supplementation experiment on a natural population of mollies was done in 1983. Excess food did not directly affect the fecundity of females in the field. A laboratory experiment was designed to determine the food level on reproduction in females. Ration had the greatest effect on somatic condition and growth, indirectly influencing fecundity. Two explanations for this strategy are suggested. A significant difference in brood size and size of young was observed between the field and …
