The analysis is based on recorded data for defining the physical systems parameters. Established parameters are mathematically related to define a descriptive model for Canal 38. the modeling procedure of 'trial and error' is used to assemble themodel with measures of merit, the integral square error, and root mean squared error. General simulation considerations are discussed for application of the mathematical model.

Chirped metallic gratings of this type have also been studied theoretically at microwave frequencies, but no attempt has been made to experimentally examine or utilize the focusing properties of these structures at microwave frequencies. This thesis presents an experimental analysis of the focusing properties of chirped metallic gratings. These gratings are designed to focus electromagnetic energy at a predetermined position by varying strip width and spacing as a function of position. The diffraction gratings are characterized, and experimentally measured results are compared to theoretical data.

Show moreUniversity of Central Florida College of Engineering Thesis; Traditionally, batch settling tests have been employed to determine the values of the settling parameters V0 and K of the Vesilind equation which represents activated sludge settling velocity as a function of solids concentration. It remains unresolved how closely batch settling tests describe settling in full-scale clarifiers. An experimental procedure was developed to determine scale factors between batch settling and full-scale solids flux curves. An experimental protocol was determined for full-scale clarifier operation, including specific criteria of necessary instrumentation and operational flexibility. Several graphical techniques were evaluated and a procedure was selected to determine a scale factor between batch and full-scale settling. The specified procedure requires determination of underflow velocity and concentration. The scale factor was approximately 0.84 as applied to the limiting flux, thus clarifiers designed from batch settling tests would be underdesigned. In addition, a methodology was developed to account for batch flux curve variability in the form of a safety factor. Finally, a design procedure was recommended to calculate clarifier area based on the scale factor determined from the batch and full-scale experiments.

Show moreUniversity of Central Florida College of Education Thesis; Federal vocational education legislation has undergone drastic changes in recent years. This study was designed to determine the educational philosophies of the leaders who pushed for the 1990 Carl D. Perkins Vocational and Applied Technology Education Act Amendments and the degree to which the amendments reflected the philosophies of those leaders. Data were collected on testimonies given before the United State[s] Congress during hearings related to the act, to identify who the leaders were. Once the leaders were identified, the published literature and testimony of each leaders was analyzed using a model developed by Lloyd Duck and the educational philosophy for each leader was identified. Finally, provisions of the act were compared to the philosophies and testimonies of the leaders to identify if the act paralleled the philosophical rationale of the leaders. This researcher found that of the leaders who pushed for the act, the majority, though not all, were of an experimentalist educational philosophy. Further analysis revealed that while the act appeared on the surface to match well with several different educational philosophies, it actually did not match the philosophies of all of the leaders. Because of this, this researcher concluded that implementation of the act may not be successful unless a new educational philosophy is established.

The results of the present study were based on responses of 330 college students to a questionnaire authored by the examiner. Results were compared to Pocs and Godow's results, and research data from Kinsey (1948, 1953) and Hunt (1972), which presented the reported frequencies of sexual activities of the parent-aged population. The comparisons suggest that although estimates of the subjects in the current study were higher in all areas than in the Pocs and Godow data, today's college students still underestimate their parents' sexual activity as compared to Kinsey and Hunt, with few exceptions. Results found significant correlations of estimations with marital status of parents, amount of and comfort with parent-child sexual discussion, subjects' religious attendance and importance, and negative emotions when considering their parents as sexual beings. Suggestions were made to conduct a future replication this research, and for parents to increase open discussion of sexual issues, to inform their children that sexuality if not just for the young.

Boris Levinson (1962) was an early advocate for the inclusion of pets in psychotherapeutic intervention. His theories have been frequently cited in research that has attempted to define the possible benefits associated with utilizing pets as an adjunct in the treatment of disturbed populations. The results of studies with varied populations indicate that a pet's presences can lower a person's anxiety level, positively increase self-concept, stimulate social interaction, provide a source of non-threatening acceptance, improve the prognosis for cardiac patients, and encourage goal-oriented behavior. However, few empirical studies have been conducted to explain the mechanisms responsible for the healthy benefits that have been associated with pet facilitated therapy. The goal of this study was to further identify the variables present in person-pet interactions that are desirable in therapeutic precesses. Thirty undergraduate students were recruited to participate in a 30 minutes simulated clinical interview. It was hypothesized that the 15 subjects in the dog-present experimental group would show significantly lower situational anxiety compared to the 15 subjects experiencing a dog-absent interview. It was also hypothesized that there would be temporal decreases in anxiety for the experimental group, and a greater degree of favorableness felt towards pets. The State-Trait Anxiety Inventory (Spielberger, et al. 1983), The Pet Attitude Scale (Templer, 1981) and behavioral measures were used to test the hypotheses. Results indicated that the dog's presence had no significant effect upon anxiety, and there were no significant changes in pet attitude. Both groups showed a consistent and significant decrease between pre- and post-interview scores measuring State and Trait Anxiety. the results of this study suggest that pet facilitated therapy has limited applicability with a college population that is typically well adjusted and high functioning. It was suggested that the subjects recruited for this study may not have had a need to utilize the dog's presence for anxiety reduction as might a clinical population.

Show moreUniversity of Central Florida College of Arts and Sciences Thesis; The primate Alu family of repetitive elements has been widely characterized. This ubiquitous class of retroposons has been found to occupy some 5% of the human genome. This hetergenous group of Short Interspersed Nucleic acid Elements (SINEs) has been theorized to possess an identifiable subfamily structure between and within various taxonomic levels in primates. It has been postulated that humans possess up to 6 Alu sequences and found evidence supporting the amplification/fixation theory in 5 subfamilies. The research presented in this thesis posits that Quentin's method of alignment used in the correspondence analysis is questionable. A reexamination using an alternative, perhaps more tenable, alignment of the Alu sequences may allow for a more lucid and accurate identification of Alu subfamily structure in the human genome.

Show moreUniversity of Central Florida College of Engineering Thesis; The objectives of this research were to quantify formaldehyde consumption due to plating and parasitic reactions and determine the magnitude and distribution of formaldehyde losses from the electroless copper plating process. Plating and rinse bath samples obtained from three electroless copper plating operations were analyzed for formaldehyde and copper in order to develop a mass balance analysis about the plating bath for periods of active production and no production. Fugitive air and stack releases of formaldehyde were estimated using emission factors developed from air sampling at the three facilities. It was determined that approximately 90% of the formaldehyde added to the plating process was consumed by some type of chemical reaction. The remaining 10% of formaldehyde represents losses from the plating operation. For the facilities with a waste plating solution stream, atmospheric losses accounted for approximately 25% of the total losses. The mass of fugitive air formaldehyde measured approximately 2.8 times that escaping through the stack. Dragout accounted for approximately 2.3% of the losses with the remaining going to the waste stream. For the facility without a plating solution waste stream, formaldehyde losses were distributed 59% to atmospheric releases and 41% to the rinse tank. Fugitive and stack releases were approximately the same at 29% of the formaldehyde losses. Formaldehyde consumption due to parasitic reactions for periods of active plating and no plating were determined for two facilities. The rate of parasitic consumption during periods of production was found to be approximately 3 times greater than that for no production. The rate of parasitic consumption was observed to increase with increasing bath temperature.

Show moreUniversity of Central Florida College of Engineering Thesis; 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, which limits the attainable chromatic values for any given luminance level. This recoupling of the chromatic and luminance components constrains the independent processing of these two components. This thesis investigates this coupling and how it effects a number of color image processing algorithms. Specifically, new algorithms for color histogram equalization, automatic white balance and color filtering are presented using the C-Y (color difference) color model. Coupling the chromatic components to the luminance produces improved white balanced results and enhances the ability of histogram equalization to increase saturation contrast. Furthermore, several adaptive filters are implemented using the C-Y color space. Because this color model closely matches the human concept of color, the noise is filtered from color components that closely match the perceptually significant quantities. This improves the results for these adaptive filters, but also requires special attention when filtering the hue component. Improper filtering of the hue component can often lead to color artifacts.

This system uses simulation modeling to capture the complex nature of semiconductor test operations. Simulation, however, is not a tool for optimizations 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 of the simulation process. That is, given a set of goals defined for performance measures, the decision support system suggests proper values for decision parameters to achieve those goals.

The leaders chosen for this study were the Florida Council for the Social Studies Board and the Association of Social Studies Supervisors. These leaders were sent a questionnaire that contained 57 statements about social studies curriculum content in a Likert scale format. The results of the survey were reported by using mean scores and frequency distributions. The Likert survey statements examined respondents' viewpoints with regard to diversity, Afrocentrism, and Eurocentrism. The results of the survey were used to infer the respondents' perceptions regarding the five research questions. 1. What was the perceived importance of considering the diverse nature of an ethnicity in respect to the development of curriculum and instruction? 2. What was the perceived level of interest regarding the incorporation of an Afrocentric perspective into the Social Studies Curriculum? 3. How did the respondents perceive the incorporation of an alternate curriculum maintaining diverse perspectives? 4. Did the respondents believe the social studies curriculum should be altered to cater to the learning styles of ethnic and cultural groups? 5. Was there a perceived need for diverse assessment techniques to gauge the academic success of students from various cultural and ethnic groups? The mean scores assigned to each research question indicated that the leaders in the social studies agreed that diverse cultures should be included within the mainstream curriculum and that alternative assessment techniques should be used to measure those ideas. However, there was little interest in permitting the ethnicity of the school's population guide curriculum and instruction decision. Furthermore, the leaders seemed more interested in a multicultural curriculum than a curriculum incorporating only an Afrocentric perspective.

Show moreUniversity of Central Florida College of Arts and Sciences Thesis; The effects of nutrient loading from avian breeding colonies into aquatic/marine ecosystems have been well documented. Documented influences include increased productivity of aquatic/marine macrophytes, elevated sediment nutrient concentrations, and increased densities of zooplankton and planktivorus fishes. The primary pathway of nutrient export from the rookery is through excreta from adult birds and their offspring. This study examined the influences of a 400-nesting pair rookery of cattle egret (Bubulcus ibis) in 1990 and a 75-nesting pair rookery of cattle egret in 1991 on a man-made freshwater treatment marsh in east central Florida. Because the fundamental intent of the created marsh (study site) was the removal of nutrients, primarily nitrogen and phosphorus, from advanced treated wastewater prior to discharge into public surface waters, the main objective of this study was to document the effects of the avian breeding colonies on water quality within the system. Secondary objectives of the study were to document influences on phytoplankton density and aquatic faunal community structure, as well as to estimate spatial and temporal limits of rookery influences. The results indicated significant water quality differences between rookery and reference sites during 1990 and 1991. The results also indicated significant differences between phytoplankton productivity and aquatic macroinvertebrate community structure between rookery and reference sites during 1990 and 1991. The effects of nutrient loading from the rookeries were confined to within 150 m and background water quality conditions were regained within one month of rookery abandonment. In effect, the 1990 and 1991 rookery sites were characterized as limited, transient "islands" of increased eutrophication within the marsh.

Show moreUniversity of Central Florida College of Engineering Thesis; In this thesis, the investigation of asymptotic stability of the series DC motor with unknown load-torque and unknown armature inductance is considered. The control technique of recursive, or backstepping, design is employed. Three cases are considered. In the first case, the system is assumed to be perfectly known. In the second case, the load torque is assumed to be unknown and a proportional-integral controller is developed to compensate for this unknown quantity. In the final case, it is assumed that two system parameters, load torque and armature inductance, are not known exactly, but vary from expected nominal values within a specified range. A robust control is designed to handle this case. The Lyapunov stability criterion is applied in all three cases to prove the stability of the system under the developed control. The results are then verified through the use of computer simulation.
