Electromagnetic Scattering From Stacked Gratings, Pok K. Kwan

Retrospective Theses and Dissertations

The theory of scattering matrices and microwave network analysis are employed to solve the problem of scattering from cascaded infinite periodic gratings. The total reflection and transmission coefficients are calculated as functions of angle of incidence, wire spacing for each grating, grating separation, wire thickness, and number of gratings that comprise the cascaded structure. Moreover, the problem of stacking dielectric slabs with periodic gratings is formulated and solved. In all cases, the Secant Corrector Spectral Iteration approach is used as a numerical method for calculating the desired currents and fields.

Finally, calculated values of the reflection and transmission coefficients are …

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. …

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 …

The responses of two crown ethers with plasticizers were evaluated for thirteen representative cations. The concentration range covered in each evaluation was 1 x 10^-1 to 1 x 10^-7 M. For those ions exhibiting Nernstian or near-Nernstian response, …

Matching Training Time To Training Need: A Procedure For Revising An Existing Supervisory Training Program, Eugene K. Cuccarese

Retrospective Theses and Dissertations

Measuring training need and in turn revising training content to reflect that need is a process that continues to plague the training practitioner. This study examines the application of Ford and Wroten's (1984) Matching Technique to a supervisory training program. Subjects were 13 non-supervisors and 13 recently promoted supervisors that were divided equally between the control and experimental conditions. A nonequivalent control group design was employed, and the data were analyzed using ANCOVA. Self-perception training need data were collected via a need survey. Both the need data and the training program content were classified in terms of management skill dimensions. …

Synchronized On-Line Microprocessor Control Of Optical Disk Recorders And Players Using Realtime Interface Hardware/Software, William C. Reese

Retrospective Theses and Dissertations

The goal of this research report is to describe clearly the development of an operational software program which utilizes a realtime interface hardware unit to synchronously control an optical disc player and optical disc recorder via an external microprocessor. The previous UCF Engineering College’s optical disc hardware configuration consisted of a Panasonic optical disc player and recorder, color monitor, video camera, and PRO-350 to control only one device (player or recorder) at a time as the microprocessor has only one serial input/output (I/O) port. The Digital Equipment Corporation’s realtime interface device provides two serial I/O ports and therefore allows the …

Retrospective Theses and Dissertations

This research project found that a solution of methanol and methylene chloride saturated with mercuric chloride was very effective at diffusing through a paint film and destroying an aluminum barrier below. The project also found evidence that mercuric chloride chemically reacts with dimethylformamide and dimethysulfoxide. The project concluded that corrosion of metals in an organic solvent media is best studied by thermal analysis.

Companding Flash Analog-To-Digital Converters, Michael P. Brig

Retrospective Theses and Dissertations

This report will demonstrate how a companding flash analog-to-digital converter can be used to satisfy both the dynamic range and resolution requirements of an infrared imaging system. In the past, infrared imaging systems had to rely on analog electronics to process a thermal image. This was costly and, in many ways, inefficient but the only way to perform the function. Digital processing was impractical because ADC conversion speeds were slow with respect to video frequencies. Furthermore, it is impossible to gain the necessary dynamic range using linear conversion techniques without large digital wordlengths. Therefore, the principles of companding flash analog-to-digital …

The Argument From Setting: Theatre In The Liberal And Fine Arts, John Gronbeck-Tedesco

Association for Communication Administration Bulletin

This essay analyzes how the institutional setting of theatre programs within either the liberal arts or the fine arts shapes the assumptions guiding administrative argument and decision making. The author contends that academic leadership operates through the exchange of reasoned claims and that coherent argumentation requires shared first principles. Program location provides such grounding by offering distinct philosophical orientations for justifying resources, curriculum, and program direction. The essay distinguishes liberal arts education as centered on generating interpretive knowledge about the human condition through evidence based inquiry, while fine arts education focuses on creating artistic analogues of human experience that communicate …

Curriculum Implications Of The New Technologies, Frederick Williams

Association for Communication Administration Bulletin

This article examines the curricular implications of emerging communication technologies, emphasizing that the central concern within the communication discipline remains the study of human use and social impacts of technological systems rather than their mechanical features. It argues that new media function primarily as extensions of existing forms, particularly as telecommunications and computing converge, enabling greater informational access, individualized communication, and distributed decision making. Rather than creating entirely new courses, the article proposes revising current communication curricula to reflect changes in media environments. Key areas for integration include the shift from mass communication to demassification through narrowcasting and text services, …
