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 …

A Survey And Analysis Of The Beginning Teacher Program In Florida And Its Relationship To Effective Education, Joanne Mullins Olson

Retrospective Theses and Dissertations

This study was conducted to determine whether there were significant factors contributing to a teacher's ability to perform effectively in the classroom. An approximate 5% stratified random sample was selected from 9,401 possible subjects in Florida's Beginning Teacher Program between 1982 and 1985. A comparison of descriptive and reportive data was performed for teachers who completed and teachers who did not complete the program.

Statistical measures included the use of contingency tables, chi-square statistic, frequency distributions and t-tests. Results suggested that a teacher's possibility of successfully completing Florida's Beginning Teacher Program was influenced by the participant's age, grade point average, …

Separation Plane Priority In Computer Image Generation, Keith A. Stump

Retrospective Theses and Dissertations

Flight simulators are devices in which air crews can be trained without the use of actual aircraft. Potentially dangerous maneuvers, such as air-to-air refueling, and destructive exercises, such as evasive action from weaponry or aerial dogfights, can be practiced repeatedly with no risk to pilot or crew. Flight simulators are cost effective since the fuel costs associated with training pilots in actual aircraft can be excessive. Flight simulators offer an alternate training method with reduced cost. The task of a visual flight simulator is to present the trainee with scenes representative of those that would be seen if the actual …

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, …

Numerical Simulation Of Air-Conditioning Heat Recovery Water Heating Systems, Amir H. Gorji

Retrospective Theses and Dissertations

A computer simulation program called TRNSYS (Transient System Simulation) was used to model two air-conditioning waste heat recovery water heating configurations. The first model is a heat recovery unit (HRU) that utilizes an 80-gallon storage tank in conjunction with a conventional home air-conditioning system. The second model is similar to the first, except that there is an additional 80-gallon preheat storage tank. An attempt was made to compare simulation results with experimental field data. However, due to problems encountered during the field tests, such as equipment and/or instrumentation failure, there were not enough experimental data to make a rigorous comparison. …

A Performance Comparison Of Solar Radiation Predictive Models For Both Fixed And Tracking Surfaces, William F. Marion

Retrospective Theses and Dissertations

Accurate performance prediction for a system utilizing solar energy requires accurate estimates of the solar radiation received by the collector surface. This thesis compares the performance of five different diffuse solar radiation models in estimating the diffuse radiation received by a tilted surface in the warm, humid climate of Central Florida.

The following models were studied: Isotropic Model, Temps and Coulson Model, Klucher Model, Hay Model, and Perez Model. The models were evaluated for both a fixed south facing surface and for three different tracking schemes suitable for photovoltaic applications. Model estimates were then compared to the solar radiation data …

A Zero Extraction And Separation Technique For Surface Acoustic Wave And Digital Signal Processing Fir Filter Implementation, Keith V. Lindsay

Retrospective Theses and Dissertations

Presented is a new method of separating the zeros of a Finite Impulse Response (FIR) filter producing optimal digital filter of surface acoustic wave (SAW) design implementation. Overviews of zero extraction algorithms and of FIR filter design using the Remez Exchange algorithm are presented (McClellen et al. 1973).

The computer aided design (CAD) procedure presented allows the designer to specify the general filter characteristic which the Remez algorithm translates to FIR time domain coefficients. These coefficients are readily translated to the frequency (z) domain, producing an Nth order polynomial in z. The characteristic polynomial is factored to determine all roots …

The Design And Implementation Of Surface Acoustic Wave Devices For Linear Fm And Nonlinear Fm Pulse Compression Technique For Radar Applications, James C. Walker

Retrospective Theses and Dissertations

The purpose of this work is to design, fabricate, and compare dispersive SAW devices using both linear FM and a new non-linear FM scheme. This new non-linear FM scheme uses the Blackman function as the modulating signal of the FM waveform. Up-chirped and V-chirped devices for both linear and the new non-linear FM scheme and their corresponding matched filters are compared.

Design considerations are discussed in detail. An efficient sampling algorithm (which can also be applied to other non-linearly modulated FM waveforms) developed to facilitate the design of the SAW devices is presented.

Switched-Capacitor Programmable Sallen And Key Lowpass Filters, Karl P. Eriksson

Retrospective Theses and Dissertations

This thesis deals with a different approach to switched-capacitor filters than previously seen by the use of a Sallen and Key topology. It is shown that a Sallen and Key second-order topology approach to a switched-capacitor filter gives reasonable filter performance results, contrary to what the literature leads one to expect. It is also shown that the Sallen and Key second-order topology with modification to a third-order section with buffers results in a high performance switched-capacitor filter with fewer components than previous switched-capacitor filters. This results in fewer monolithic chip size requirements, reduced power requirements, and less cost. Higher order …

Angular-Distribution Of Fluorescence From Photoionization-Produced He+ (N=2), J. Jiménez-Mier, C. Denise Caldwell, D. L. Ederer

Faculty Bibliography 1980s

We report the first measurement of the angular distribution of the 304-Å He + ( n = 2 ) radiation following photoionization. This distribution reflects the alignment of the ion, which is related to the fraction ξ = σ ( 2 p , k d ) [ σ ( 2 p , k s ) + σ ( 2 p , k d ) ] of d component in the electron wave. The experimental angular distributions correspond to alignments of -0.62 ± 0.03 and -0.62 ± 0.02 at photon energies of 65.5 and 66.5 eV, respectively. These translate into ratios …

Individual Differences In Training Performance: The Derivation Of A Prediction Model, Brenda J. Hoskin

Retrospective Theses and Dissertations

This research examines the use of non-cognitive personality measures as supplements to traditional cognitive ability measures for predicting training performance. The Hogan Personality Inventory (HPI) significantly predicted an overall performance measure (R² = .17) for Navy BE&E Students (N = 155). However, when applied as a supplemental predictor composite to the military cognitive measure (ASVAB), the resulting increase in R² (.04) failed to attain significance, F(6, 144) = 2.17, p > .05). In further analyses, several HPI and ASVAB scales combined to significantly predict selected performance criteria. The ASVAB remained as the primary source of information. It is quite …

The Relationship Between Perceptual Learning And Psychmotor Task Variety: Contextual Interference Effects, Sherrie Ann Jones

Retrospective Theses and Dissertations

Task variety during training was manipulated to assess residual effects on skill acquisition during subsequent transfer to a novel perceptual motor task. The task involved tracing a four-point star pattern displayed on a personal computer with a "mouse," while receiving variation in visual feedback from the CRT display. Variety during training involved two cases of abnormal visual feedback (left-right reversal and 90 degree tilt) Task variety (i.e., visual feedback) was manipulated and counterbalanced in four levels: alternated variety (trial by trial), blocked variety (in five trial sets), no variety (i.e., one type of feedback), and a control condition that trained …
