Creating User Centred Designers., Andrée Woodcock

DRS Biennial Conference Series

The failure of practicing designers and engineers to encompass ergonomics issues in their practice has long been a source of frustration for both ergonomists and customers - ergonomists, because they know their discipline could inform and benefit the end product, and customers suffer the consequences of poor design. Although the relationship between ergonomics and design has been well explored, and has led to the development of various solutions - these have not had the major impact on design that was desired. This paper looks at a new approach, through education, that might lead to the creation of more user centred …

A P300-Based Brain-Computer Interface: Testing An Alternative Method Of Communication, Eric W. Sellers

USF Tampa Graduate Theses and Dissertations

The current study evaluates the effectiveness of a Brain-Computer Interface (BCI) system that operates by detecting a P300 elicited by one of four randomly presented stimuli (i.e., YES, NO, PASS, END). Two groups of participants were tested. The first group included three ALS patients that varied in degree of disability, but all retained the ability to communicate; the second group included three Non-ALS controls. Each participant participated in ten experimental sessions during a period of approximately 6 weeks. Sessions were conducted either at the participant's home or in the lab. During each run the participant's task was to attend to …

Road Crack Condition Performance Modeling Using Recurrent Markov Chains And Artificial Neural Networks, Jidong Yang

USF Tampa Graduate Theses and Dissertations

Timely identification of undesirable pavement crack conditions has been a major task in pavement management. Up to date, myriads of pavement performance models have been developed for forecasting pavement crack condition with the traditional preferred techniques being the use of regression relationships developed from laboratory and/or field statistical data. However, it becomes difficult for regression techniques to predict the crack performance accurately and robustly in the presence of a variety of tributary factors, high nonlinearity, and uncertainty. With the advancement of modeling techniques, two innovative breeds of models, Artificial Neural Networks and Markov Chains, have drawn increasing attention from researchers …

The Contribution Of Executive Functions To Emergent Mathematic Skills In Preschool Children, Kimberly Espy, Melanie D. Mcdiarmid, Mary F. Cwik, Melissa Meade Stalets, Arlena Hamby, Theresa E. Senn

Developmental Cognitive Neuroscience Laboratory: Faculty Publications

Mathematical ability is related to both activation of the prefrontal cortex in neuroimaging studies of adults and to executive functions in school-age children. The purpose of this study was to determine whether executive functions were related to emergent mathematical proficiency in preschool children. Preschool children (N= 96) were administered an executive function battery that was reduced empirically to working memory (WM), inhibitory control (IC), and shifting abilities by calculating composite scores derived from principal component analysis. Both WM and IC predicted early arithmetic competency, with the observed relations robust after controlling statistically for child age, maternal education, and child vocabulary. …

Generalized Design Of Diffractive Optical Elements Using Neural Networks, Ajay Pasupuleti, Anand Gopalan, Ferat Sahin, Mustafa A.G. Abushagur

Presentations and other scholarship

Diffractive optical elements (DOE) utilize diffraction to manipulate light in optical systems. These elements have a wide range of applications including optical interconnects, coherent beam addition, laser beam shaping and refractive optics aberration correction. Due to the wide range of applications, optimal design of DOE has become an important research problem. In the design of the DOEs, existing techniques utilize the Fresnel diffraction theory to compute the phase at the desired location at the output plane. This process involves solving nonlinear integral equations for which various numerical methods along with robust optimization algorithms exist in literature. However all the algorithms …

Detecting Submerged Features In Water: Modeling, Sensors, And Measurements, Charles R. Bostater, Luce Bassetti

Ocean Engineering and Marine Sciences Faculty Publications

It is becoming more important to understand the remote sensing systems and associated autonomous or semi-autonomous methodologies (robotic & mechatronics) that may be utilized in freshwater and marine aquatic environments. This need comes from several issues related not only to advances in our scientific understanding and technological capabilities, but also from the desire to insure that the risk associated with UXO (unexploded ordnance), related submerged mines, as well as submerged targets (such as submerged aquatic vegetation) and debris left from previous human activities are remotely sensed and identified followed by reduced risks through detection and removal. This paper will describe …

Ac/Dc Switch Mode Power Supply With Power Factor Correction Using Direct Energy Transfer Concept, Issa Batarseh, Peter Kornetzky, Shiguo Luo, Weihong Qiu

UCF Patents

Power factor correction (PFC) "flyboost" cell with a transformer having primary winding connected to input power and secondary winding connected to output rectifier, which has both functions as a flyback transformer and boost inductor. Combining the flyboost cell with DC/DC converter cells, forms a single-stage PFC converters. Both cells share one main switch and one controller. Letting the flyboost cell operate at Discontinous Coduction Mode requires a simple control for high power factor. Through flyboost cell, part of output power is processed once by main switch, and is referred to as direct power transfer (DPT), which will signficantly improve efficiency. …

Perceptual Evaluation Of Point-Based Object Representation, Paul Schwarz

Computer Science Honors Theses

Researchers have proposed several methods of representing three-dimensional objects in computer memory along with different methods of displaying these objects on two-dimensional computer displays. Using a polygon-based representation that linearly interpolates between a set of sample points is by far the most popular way of representing objects today, mostly because of its ability to display an object on a computer screen at a fast and consistent rate. However, as graphics hardware increases in speed, polygon-based models prove to be increasingly inefficient. Point-based representations have been proposed that consist of densely sampling some surface and using solely the samples to portray …

Does The Halting Necessary For Hardware Trace Collection Inordinately Perturb The Results?, Myles G. Watson

Theses and Dissertations

Processor address traces are invaluable for characterizing workloads and testing proposed memory hierarchies. Long traces are needed to exercise modern cache designs and produce meaningful results, but are difficult to collect with hardware monitors because microprocessors access memory too frequently for disks or other large storage to keep up. The small, fast buffers of the monitors fill quickly; in order to obtain long contiguous traces, the processor must be stopped while the buffer is emptied. This halting may perturb the traces collected, but this cannot be measured directly, since long uninterrupted traces cannot be collected. We make the case that …

Synthesizing Realistic Spine Motion Using Traditional Rig Controllers, Jabbar Raisani

Computer Science Honors Theses

This thesis presents a specific method for simulating realistic spine motion through the use of traditional rig control objects. The spine's motion and flexibility is based on a curve as opposed to the more traditional three bone spine. This allows for a more fluid animation more closely resembling that of a spinal column. However, this setup keeps the traditional three control rig setup in order to mimic the control system of a traditional three bone spine. Currently, three bone systems are well understood by animators and the motion is easy to control. The problem with this setup is that although …

1-Hyperbolic Projection For User Interfaces, Alexander Kolliopoulos

Computer Science Honors Theses

The problem of dealing with representations of information that does not fit conveniently within allotted screen space is pervasive in graphical interfaces. While there are techniques for dealing with this problem in various ways, some properties of such existing techniques are not satisfying. For example, global structure of information may be lost in favor of local focus, or information may not be mapped into a rectangular area. The 1-hyperbolic interface is proposed to deal with some of these deficiencies, and the mathematics involved in display and interaction are derived. The calculations necessary for this interface are easy to implement, and …

September 2003 saw trade talks pursuing the Doha Development Agenda at the Cancún WTO Ministerial Meeting collapse, primarily over the disagreements between rich and developing countries regarding agriculture. Despite the great pessimism that ensued, on August 1, 2004, WTO negotiators from 147 countries announced a breakthrough in negotiations to liberalize trade in agricultural products. The most striking aspect of this new framework agreement is the proposed elimination of agricultural subsidies by rich countries in return for developing countries opening up their markets to more imports. At the same time, WTO dispute resolution panels have delivered stunning decisions against the U.S. …

Globalization, Ecotourism, And Development In The Monte Verde Zone, Costa Rica, Edgar Allan Amador

USF Tampa Graduate Theses and Dissertations

Ecotourism has been promoted globally as a model for sustainable development because it simultaneously benefits the environment and the residents of the given destination. However, many conservationists have questioned the long term sustainability of ecotourism as it is difficult to mitigate the impact of even low levels of tourism on a particular ecosystem. Further, social scientists including anthropologists have similarly questioned whether most residents of a particular destination actually benefit significantly from the alternative tourism economy.

The Globalization Research Center in cooperation with the Monteverde Institue in the Monte Verde Zone, Costa Rica, is undertaking a longitudinal study -- dubbed …

What's In A Name? Keeping The Va In Arnova, Roger A. Lohmann

Faculty & Staff Scholarship

As the name suggests, Voluntary Action (VA) was one of the constituent interests in the formation of ARNOVA. The popularity of nonprofit organizations (NO) among researchers, scholars and students threatens to overwhelm the scholarly interest in voluntary action. Yet, this latter topic is both more interesting theoretically and more important to larger questions of democracy and local and national community and therefore needs to be preserved and protected.
