Implementation Of Ultrafast Optical Characterization Techniques, Nicholas J. Croglio

Retrospective Theses and Dissertations

The single beam Z-Scan technique, a two beam Pulse-Delay Modulation Technique (PDMT), and a combination of these methods are implemented to measure both nonlinear absorption and nonlinear refraction in semiconductors. The laser source used is a Kerr Lens Modelocked (KLM) Ti:sapphire laser producing tunable near IR 100 femtosecond pulses of ~5 nJ of energy per pulse at a 90 MHz repetition rate. Specifically we monitor two photon absorption and the bound electronic nonlinear refraction in ZnSe and this nonlinear refraction in ZnS. These techniques open the spectral range where these nonlinear optical parameters can be measured by allowing tunable high …

Color Image Enhancement Using Both Chromatic And Luminance Components, George Eric Hague Ii

Retrospective Theses and Dissertations

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, …

An Efficient Method For Representing And Computing Transitive Closure Over Temporal Relations, Vincent J. Kovarik

Retrospective Theses and Dissertations

The need for temporal reasoning is found throughout the engineering disciplines. James Allen introduced a representation for temporal reasoning based upon the concept of intervals. This approach provides a rich set of temporal relations for reasoning over events and changes in state. The full temporal algebra is NP-complete however. The algorithm developed by Allen executes in 0(n³) time but only ensures consistency between any three intervals.

This research presents an approach to representing interval relations as a bit-encoded form which captures the relationships between the end-points of the intervals. A bit-algebra is then defined which provides an …

Using Electronic Portfolios To Archive Student Performance, Phyllis M. Olmstead

Retrospective Theses and Dissertations

This study regards the use of portfolios for evaluating and documenting student progress and performance. In consideration of the far reaching and global nature of education, the researcher included educators from both the United States and other countries. Based upon the great importance that many countries and states have placed upon servicing students by alternative means, the population sample examined included 500 teachers instructing by both conventional and distance education modalities; Many current educational reform measures and legislative issues concern the attainment of job skills; therefore, both vocational and non-vocational instructors were included in the study.

Examined in the study …

Synthesis Of Numerical Integrators For The Real-Time Digital Simulation Of Continuous Systems, Michael James Panzitta

Retrospective Theses and Dissertations

Real-time digital simulation is a powerful means for engineers and scientists in government, industry, and academia to perform research and training as well as serving as a basis for many commercial applications. Due to the special constraints imposed by digitally simulating continuous systems in real time, however, many of these systems either require costly high-speed components or are unable to provide suitable performance characteristics using affordable computers.

This dissertation describes a new technique for the synthesis of numerical integrators specifically designed for the real-time digital simulation of continuous systems. This methodology is based upon the fact that the state derivatives …

A Model Cylindrical Magnetron Vlasov Distribution Function, D. J. Kaup, S. Roy Choudhury

Faculty Bibliography 1990s

The analysis of the planar magnetron Vlasov distribution function [Phys. Fluids 31, 2362 (1988)] is extended to the cylindrical case. In momentum space, the model distribution function is f(w,p(theta)) = Ne(-betaww)e-(OMEGAbetatheta/4p0)(ptheta-p0)2 where w(p(theta)) is the single particle energy (angular momentum), beta(w)(beta(theta)) is the inverse of the thermal energy associated with variations in w(p(theta)), p0 is the angular momentum at the cathode, and OMEGA is the electron cyclotron frequency (= eB0/mc). The problem is shown to be too ''stiff '' numerically to permit a pure numerical solution even using very high accuracy and state-of-the-art numerical schemes. It is shown that one …

Value Of A Boehmian At A Point And At Infinity, Piotr Mikusinski, Mourad Tighiouart

Faculty Bibliography 1990s

We define the notion of a value of a Boehmian at a point and study its properties. We prove that a Boehmian which has a value at a point is a Borel measure in a neighborhood of that point. We also define the notion of a value of a Boehmian at infinity.

Integration Of Artificial Neural Networks And Simulation Modeling In A Decision Support System, Kenney Lecroy

Retrospective Theses and Dissertations

A simulation based decision support system is developed for AT&T Microelectronics in Orlando. This system uses simulation modeling to capture the complex nature of semiconductor test operations. Simulation, however, is not a tool for optimization by itself. Numerous executions of the simulation model must generally be performed to narrow in on a set of proper decision parameters. As a means of alleviating this shortcoming, artificial neural networks are used in conjunction with simulation modeling to aid management in the decision making process. The integration of simulation and neural networks in a comprehensive decision support system, in effect, learns the reverse …

Communication Education Transformations: Implications For Curricular Change, Chris R. Sawyer, Phyllis Miller, Ralph R. Behnke

Journal of the Association for Communication Administration

This article explores the implications of communication education transformations for curricular change in the U.S. Differences in education and training between public relations (PR) practitioners and journalists reflect, in part, effects of certain pressures brought to bear upon these professions. Any edge which graduates may have in the marketplace will depend on the extent to which their communication programs have focused on initial detection and measurement of related talents, skill development and enhancement, and discovery of communication-related careers that depend on the integration and application of these skills. With respect to faculty placement, infusing PR faculty into existing communication programs …

Alternative Career Opportunities, Or, Don't Sell Yourself Short!, David Balthrop

Journal of the Association for Communication Administration

This article will attempt to discuss who is making an attempt to prepare their students for work outside of the field of study; pose the question of whose responsibility is it for preparing those students: faculty, universities and colleges, or the students themselves. In a survey sent out to all colleges and universities in Kentucky, only a small percentage (fewer than 3%) of the surveys returned acknowledged any help in the form of organized, structured post-graduation job opportunity discussions. All the forms returned indicated that the students wanted and needed that type of instruction. In order to locate other job …

Alternative Assessment In Speech Communication, Ellen A. Hay

Journal of the Association for Communication Administration

This article aims to promote alternative assessment in the field of speech communication. Speech communication departments in a number of colleges and universities have adopted alternative practices as they have developed their assessment programs. For example, the faculty at the University of Missouri-Kansas City examined and redesigned their curriculum so that students were required to show competence in interpersonal communication, critical thinking, language use, leadership, reading, research, public speaking, cultural appreciation, writing, decision making, theoretical understanding, and ethical/philosophical appreciation. Clearly, developing and implementing alternative assessment strategies is time consuming and costly. First, alternative assessment more fully meets the demand for …

Oral English Proficiency Requirements For Itas In U. S. Colleges And Universities: An Issue In Speech Communication, Robert C. Dick, Brenda M. Robinson

Journal of the Association for Communication Administration

This article explores the nature and extent of oral English proficiency training that international teaching assistants (ITA) need for their faculty and staff roles in U.S. colleges and universities. In surveys of campuses in the Illinois system, the most frequent single complaint among undergraduates was that the ITA had language problems which interfered with the students' comprehension of classroom material. The Test of English As a Foreign Language (TOEFL) has been in existence since 1964, assessing the English usage of English-as-a-second-language students applying for admission to colleges and universities. The Test of Spoken Language, designed by the Educational Testing Service, …
