Remote Labs: Design And Implementation Issues, Samer M. Aoudi

Electronic Theses and Dissertations 2000 - 2009

This thesis proposes the use of remote laboratory experiments in distance education as a tool to add a reality factor to the distance learning process, thus combining the convenience of distance education with the effectiveness of the traditional physical campus, through its laboratories and technological resources. Moreover, this research studies the different aspects of distance education and remote labs and then provides a proposition to develop an effective remote laboratory setup. Furthermore, it introduces and discusses the different components of a general remote lab experiment and applies the proposed process to an actual remote lab experiment, namely 'The Characteristics of …

Seafinding Orientation Of Hatchlings Exposed To Filtered Lighting: Effects Of Varying Beach Conditions, Susan Mary Tuxbury

Electronic Theses and Dissertations 2000 - 2009

Under normal conditions, hatchling sea turtles crawl toward the ocean but streetlights placed on coastal roadways can attract the turtles toward land. Two light filters were designed to exclude the shorter light wavelengths most attractive to turtles. I did laboratory tests to determine if green turtle and loggerhead hatchlings oriented normally ("seaward") in the presence of filtered lighting. Light passed through either filter (#2422 acrylic and NLW) attracted the turtles unless coastal cues (an elevated horizon) were strong or background (full moon) illumination was present. Green turtles and loggerheads responded differently to the same filters, indicating that neither filter provided …

Teaching Sight Words To Students With Mental Retardation And Learning Disabilities: Constant Time Delay Versus Interspersal Of Known Items, Melissa Gail Knight

Electronic Theses and Dissertations 2000 - 2009

This study compared the efficacy and efficiency of using constant time delay (CTD) with interspersal of known items (IKI) paired with an error correction technique to teach sight words to students with mild mental retardation and learning disabilities. Time delay is a technique that transfers stimulus control from a controlling prompt (a prompt that results in correct task performance) to the discriminative stimulus (stimulus presented before a response can occur) by delaying the presentation of the prompt after the stimulus has been presented. During the initial trial, the delay between prompt and stimulus is at 0-seconds; during all other trials …

The Use Of Nesting Initiation Dates Of Roseate Spoonbills ( Ajaia Ajaja) In Northeastern Florida Bay As An Ecosystem Indicator For Water Management Practices, 1935--1999, Rodriguez Elsa Marcella Alvear

Electronic Theses and Dissertations 2000 - 2009

Quantity and timing of freshwater flow from the Everglades to Florida Bay varied under different water management practices in the twentieth century, with negative ecological repercussions. Ecological indicators that respond to differences in hydrology, such as wading bird colony dynamics, can be used for hydrological restoration projects. I examined the possibility of using timing of nesting of Roseate Spoonbills (Ajaia ajaja) in northeastern Florida Bay as an ecological indicator. Nest initiation dates (N = 51) from 1936--1999 (x = November 25) were calculated from numerous published and unpublished sources. The dates were strikingly consistent and did not show significant trends …

Underwater Analysis Of The Behavioral Development Of Free-Ranging Atlantic Spotted Dolphin Calves (Birth To 4 Years Of Age), Jessica Ann Bayer

Electronic Theses and Dissertations 2000 - 2009

This investigation is the first to focus on the underwater behaviors and development of free-ranging Atlantic spotted dolphin (Stenella frontalis) mothers and calves. Underwater video recordings of 30 mother/calf pairs, during the calves' first three years of life, and 10 additional videos of four-year-old calves, were analyzed. Behavioral event frequencies were compared to the calf's age bracket (i.e. year-one, two, three and four). Results demonstrate an increase in calf independence in year-four shown by a significant reduction in Nursing Act behaviors, significantly more Feeding/Foraging behaviors, and increased behaviors performed in the proximity of individuals other than the mother or alone. …

William A. Dunning Revisited: The Mind Or Malice Of Reconstruction?, Kathleen P. Barsalou

Electronic Theses and Dissertations 2000 - 2009

Historian William A. Dunning was responsible for the first scholarly treatment of the Reconstruction era. The terms which his contemporaries used to describe him differ strikingly from those historians may choose today. Since the 1930s, American historiography has reflected the new emphasis on sociology and psychology with a radical shift in subject matter away from the traditional political focus. Surely, certain truths are known to the modern historian which were not known to those who lived earlier. However, to discard the insights of one generation of historians is, perhaps, to ignore some of history's most important resources.

Soilguide (Soil Guide) : A Handbook For Understanding And Managing Agricultural Soils, Geoff Allan Moore

Bulletins 4000 -

This handbook integrates the current knowledge of soils in south-western Australia in a user-friendly form. It describes how to assess which soil properties influence production and land degradation in the agricultural area and summarises management options to remedy or minimise soil limitations. The potential for growing a large range of crops and pastures can be assessed. In particular, the links between soil morphology, soil properties, management and agronomy are emphasised. The manual is designed for use at the paddock scale or for site assessment, but it can also be used at a catchment or regional scale. It is specifically designed …

The Intergenerational Transmission Of Grandmother-Grandchild Co-Residency, Richard K. Caputo

The Journal of Sociology & Social Welfare

This study examined national data from two women's cohorts to determine the likelihood that Black grandmothers who resided with grandchildren were more likely than other grandmothers were to have daughters who resided with grandchildren. Of 1098 co-resident grandmothers, 390 (36%) were in the younger of the two cohorts, 603 (55%) were in the older, and 105 (9%) were in both, comprising the sub-sample of grandmothergrandchild mother-daughter pairs. A significantly higher proportion of mothers in the grandmother-grandchildm other-daughterp airs were Black (83%) compared to 37% of the mothers among the non-paired ever coresident grandmothers. The study also found, by proxy, that …

Ramirez Solar House : A Case Study Of Early Solar Design, Joanna Kendig

Theses

The Ramirez Solar House in the Delaware Water Gap National Recreation Area is an early historic example of passive solar design. The house was designed by Henry N. Wright, a significant contributor in solar research. Wright's 1944 design with a large window wall and generous overhangs represents a significant step in solar design development. The house, now under the stewardship of National Park Service, has been nominated for the National Register of Historic Places.

The Ramirez House's solar performance was a subject of this study. Instrumentation was set up to record temperatures, humidity and illumination in the unoccupied and un-heated …

Teaching The Origins Controversy: Science, Or Religion, Or Speech?, David K. Dewolf, Stephen C. Meyer, Mark Edward Deforrest

Utah Law Review

One can hardly imagine a more contentious issue in the American culture wars than the debate over how biological origins should be taught in the public schools. On the one hand, the National Academy of Sciences, the National Center for Science Education, and the American Civil Liberties Union have insisted that any departure from a strictly Darwinian approach to the issue constitutes an attack on science itself, and even an unconstitutional intrusion of religion into the public school science curriculum. On the other hand, many parents and religious activists have long rebelled against what they perceive as a dogmatic attack …

Tribute: Justice I. Daniel Stewart, Richard Cameron Blake

Utah Law Review

The curtain is now closed on Justice Stewart's remarkable performance on the Utah Supreme Court stage, opening the door for him to pursue other interests and influence the law in other ways. As is to be expected, his Court performance will be remembered differently by different people. Many will remember him as the "Thorough" (meaning "Slow") Justice; just as he went through ten drafts of discovery questions, he was famous at the Court for going through dozens of opinion drafts (fifty-one drafts is purportedly his maximum). One attorney approached me one day during my clerkship and said, "Tell the Judge …

Failed Markets, Failing Government, Or Both? Learning From The Unintended Consequences Of Utah Consumer Credit Law On Vulnerable Debtors, Christopher L. Peterson

Utah Law Review

Although for millennia the Western tradition looked upon the taking of interest with a jaundiced eye, consumer credit has become an integral and accepted part of the American economy. Nevertheless, throughout the twentieth century federal and state government institutions have struggled with the dual needs of facilitating creditors' business ventures and simultaneously protecting vulnerable debtors from onerous obligations.

Punishing The Saints For Their "Peculiar Institution": Congress On The Constitutional Dilemmas, L. Rex Sears

Utah Law Review

The palpable connection between Mormon polygamy and that political subdivision of the Union that was first Utah Territory, and then the State of Utah, proved a fertile source of constitutional perplexity, and over time, generated a significant body of constitutional debate in Congress. The lessons taught by reviewing these debates are not all positive. The debates over exclusion and expulsion stand as an alarming illustration of how the flames of popular prejudice can push congressional majorities to embrace what had but recently been constitutionally unthinkable. Likewise, Congress's eventual acceptance of the myth that polygamists could be disfranchised for their criminal …

Dynamic Re-Optimization Of A Fed-Batch Fermentor Using Adaptive Critic Designs, Donald C. Wunsch, M. S. Iyer

Electrical and Computer Engineering Faculty Research & Creative Works

Traditionally, fed-batch biochemical process optimization and control uses complicated off-line optimizers, with no online model adaptation or re-optimization. This study demonstrates the applicability of a class of adaptive critic designs for online re-optimization and control of an aerobic fed-batch fermentor. Specifically, the performance of an entire class of adaptive critic designs, viz., heuristic dynamic programming, dual heuristic programming and generalized dual heuristic programming, was demonstrated to be superior to that of a heuristic random optimizer, on optimization of a fed-batch fermentor operation producing monoclonal antibodies

Detection And Classification Of Impact-Induced Damage In Composite Plates Using Neural Networks, Rohit Dua, Steve Eugene Watkins, Donald C. Wunsch, K. Chandrashekhara, Farhad Akhavan

Electrical and Computer Engineering Faculty Research & Creative Works

Artificial neutral networks (ANN) can be used as an online health monitoring systems (involving damage assessment, fatigue monitoring and delamination detection) for composite structures owing to their inherent fast computing speeds, parallel processing and ability to learn and adapt to the experimental data. The amount of impact-induced strain on a composite structure can be found using strain sensors attached to composite structures. Prior work has shown that strain-based ANN can characterize impact energy on composite plates and that strain signatures can be associated with damage types and severity. This paper reports the extension of this approach for damage classification using …

Measurement And Monitoring Of Microwave Reflection And Transmission Properties Of Cement-Based Specimens, Sergey Kharkovsky, M. F. Akay, U. C. Hasar, C. D. Atis

Electrical and Computer Engineering Faculty Research & Creative Works

The results of measurement and monitoring of reflection and transmission properties of cement-based specimens (blocks of mortar, concrete) during long time of their service lives, including hydration process, and different curing conditions at microwave frequencies (X-band) are presented. A simple and inexpensive measurement system that utilizes the nondestructive and contactless free space method is used. Dependencies of the reflection and transmission coefficients on water-to-cement ratio, preparing and curing conditions of the specimens are demonstrated. It is shown that the reflection coefficient is approximately stable after hydration process while the transmission coefficient changes during long time of the specimen''s service life. …

Multi-Level Voltage-Source Duty-Cycle Modulation: Analysis And Implementation, Keith Corzine, J. R. Baker

Electrical and Computer Engineering Faculty Research & Creative Works

Multi-level converters have become increasingly popular due to high power quality, high-voltage capability, low switching losses, and low EMC concerns. Considering these advantages, the multi-level converter is a suitable candidate for implementation of future naval ship propulsion systems. This paper focuses on modulation techniques for the multi-level converter. In particular, a novel voltage-source method of multi-level modulation is introduced and compared to existing methods. The proposed method is discrete in nature and can therefore be readily implemented on a digital signal processor (DSP). The method is also readily extendable to any number of voltage levels. Results of experimental implementation are …

Reduced Parts-Count Multi-Level Rectifiers, Keith Corzine, J. Yuen, J. R. Baker

Electrical and Computer Engineering Faculty Research & Creative Works

Multi-level power converters have gained much attention due to their high power quality, low switching losses, and high-voltage capability. These advantages make the multi-level converter a candidate topology for the next generation of naval ship propulsion systems. The primary disadvantage of these systems is the large number of semiconductors involved. This paper presents a reduced parts-count rectifier which is well suited for naval rectifier applications where bi-directional power flow is not required. The proposed converter is analyzed and experimentally verified on an 18 kW four-level rectifier/inverter system.

A Nonlinear Voltage Controller With Derivative Adaptive Critics For Multimachine Power Systems, Ganesh K. Venayagamoorthy, Donald C. Wunsch, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

Based on derivative adaptive critics, a novel nonlinear optimal voltage/excitation control for a multimachine power system is presented. The feedback variables are completely based on local measurements. Simulations on a three-machine system demonstrate that the nonlinear controller is much more effective than the conventional PID controller equipped with a power system stabilizer for improving dynamic performance and stability under small and large disturbances.

Misplaced Marketing: Why Television Is The “Wrong” Environment For Public Service Advertising Campaigns, Joyce M. Wolburg

College of Communication Faculty Research and Publications

Notes that research has shown that advertising efforts to promote social causes rarely reach meaningful levels of effectiveness. Points out that while the media provide the right emotional climate for advertising messages that encourage consumption, it follows that the media provide the wrong environment for messages that discourage consumption or other behaviors. Concludes that money spent might best be redirected to other prevention efforts that more directly accomplish the social program’s goals.

The "Risky Business" Of Binge Drinking Among College Students: Using Risk Models For Psas And Anti-Drinking Campaigns, Joyce M. Wolburg

College of Communication Faculty Research and Publications

To assist creators of public service announcements and anti-drinking campaigns, this study provides an in-depth examination of the risks of binge drinking from the perspective of college students. Using current risk models for guidance, key elements from the qualitative data in the study are addressed, including perceived risks and their severity, vulnerability to risks, self-efficacy, response efficacy, benefits from ritual functions, and other costs or benefits based on students' attitudes and beliefs. An integrated risk perception model is introduced. Student participants enumerated extensive risks; however, they generally felt invulnerable to the consequences. Most adopted a management style of “taking chances” …

The Effects Of Expectancy Disconfirmation On Outcome Satisfaction In Police-Citizen Encounters, Michael D. Reisig, Meghan S. Stroshine

Social and Cultural Sciences Faculty Research and Publications

This study tests the expectancy disconfirmation model using survey data from citizens who recently had police encounters. We find support for the expectancy disconfirmation model's primary hypothesis that increased disparity between expectations of police performance and actual service inversely affects citizen satisfaction with the way the police handle encounters. This finding persists for both voluntary (e.g. breaking and entering victims) and involuntary (e.g. traffic citations) police encounters. Our results also suggest that the scope of the expectancy disconfirmation model is limited. For example, the disparity between expectations and actual service is not correlated with citizen satisfaction with the police in …

Role Playing And Cooperative Learning In The Ais Course, Dennis F. Togo, Kristi Jane Yuthas

Business Faculty Publications and Presentations

The accounting information systems course is often viewed as difficult to teach because it contains topics that are less quantifiable and structured in comparison to courses in financial or managerial!cost accounting. Yet, many AIS instructors have developed successful teaching techniques that are suited to the AIS course. A creative teaching approach for the AIS course is that of role-playing organizations and their operations, especially for transaction cycles. In addition, cooperative learning can be nicely coupled with role playing because of their common emphases on social interdependence and shared learning. The benefits and guidelines for cooperative learning and role playing are …
