Feature Saliency In Artificial Neural Networks With Application To Modeling Workload, Kelly A. Greene

Theses and Dissertations

This dissertation research extends the current knowledge of feature saliency in artificial neural networks (ANN). Feature saliency measures allow for the user to rank order the features based upon the saliency, or relative importance, of the features. Selecting a parsimonious set of salient input features is crucial to the success of any ANN model. In this research, several methodologies were developed using the Signal to Noise Ratio (SNR) Feature Screening Method and its associated SNR Saliency Measure for selecting a parsimonious set of salient features to classify pilot workload in addition to air traffic controller workload. Candidate features were derived …

Re-Cycling The Menstrual Cycle: A Multidisciplinary Reinterpretation Of Menstruation, Heather H. Rea

Masters Theses

This thesis offers a reinterpretation of the human female menstrual cycle that understands the process as positive, functional, and practical experience. Standard western definitions and understandings of menstruation use negative terminology and focus on menstrual blood as an indicator of failed conception. This view contributes significantly to the negative perception women have of menstruation in general, their own menstrual cycles, and ultimately of their femaleness. This fundamental, physiological process that symbolizes femaleness, the menstrual cycle, has been defined both, bio-medically and culturally, as a negative experience. I propose a reconceptualization of the menstrual cycle that is not only a tool …

Lead Shot Concentration In Soil At The Overton Wildlife Management Area, Nevada, George R. Bertoty

UNLV Theses, Dissertations, Professional Papers, and Capstones

During the spring of 1998, soil samples were collected from two areas at the Overton Wildlife Management Area (OWMA), located in the Moapa Valley of Clark County, Nevada. Lead shot has been banned for the hunting of waterfowl since 1986 but is still legal for upland game hunting. Both types of hunting occur at OWMA. One area sampled is a cultivated field and serves primarily as a dove hunting area. The other area is primarily a waterfowl hunting area and is flooded during the waterfowl-hunting season. Lead shot was recovered from 83% of the samples from the dove hunting area, …

Hybrid Force-Feedback Control For Virtual Environments, Carol Chesney

Link Foundation Modeling, Simulation and Training Fellowship Reports

The scope of this project is the design and implementation of a force-feedback device that utilizes brakes as well as motors for hybrid force control.. The device is a pen-sized device for planar point force-feedback. The design and software are implemented with consideration towards extending the force-feedback technology to three dimensions. The benefits of such a hybrid device include increased safety and realism. Larger forces can be reflected safely in the form of impenetrable constraints and instabilities can reduced or eliminated. The passive force component is the only way to accommodate the model of static friction. Delay in force measurement …

Computer Synthesis Of Spectroradiometric Images For Color Imaging Systems Analysis, Garrett M. Johnson

Theses

A technique to perform full spectral based color calculations through an extension of OpenGL has been created. This method of color computations is more accurate than the standard RGB model that most computer graphics algorithms utilize. By maintaining full wavelength information in color calculations, it is also possible to interactively simulate and display many important color phenomena such as metamerism and fluorescence. This technique is not limited to creating simple images suitable for interactive display, however. Using this extension, it is also possible to synthesize spectroradiometric images of arbitrary spatial and spectral resolution, for use in color imaging system analysis.

Measurement Of The Baroreceptor Sensitivity Index (Brsi) In The Frequency Domains, Tanvir Raquib

Theses

Time domain analysis for calculating the Baroreceptor Sensitivity Index (BRSI) did not always provide an accurate result. It also had another limitation in that it could not show the influence of the autonomic nervous system for different subjects. The correlation coefficient is a mechanism that was used to either accept or reject the BRSI values in the time domain but the correlation coefficient values changed drastically depending on how many sample points were selected for the calculation.

On the other hand, frequency domain analysis for the BRSI calculation was relatively easier and provided more accurate information compared to the time …

Fatigue: Investigation Of A Human Factor For Regional Airline Pilots, Doug Mikkelsen

Master's Theses - Daytona Beach

This study analyzed the causes of regional airline pilot fatigue and the impact on pilot performance. An instrument was developed and refined through a field study validation by a panel of experts. The final instrument was distributed to three groups of regional airline pilots. The data supported the literature review, which revealed many causes of pilot fatigue, including flight crew schedules that are not compatible with human limitations; Federal Aviation Regulations (FARs) that have not evolved with the advancement of aircraft performance and the public demand for 24 hour availability of flights; and poor personal habits. An analysis of the …

Simulation Of The Human Lung, Noah Syroid, Dwayne Westenskow, Volker E. Boehm

Utah Space Grant Consortium

A human lung simulator was implemented using a model based on the Fick principle. The simulator is designed to emulate C0₂ production and 0₂ consumption in the body and gas exchange in the lung. The implementation consists of hardware and software to control the flow of gases entering and leaving a ventilated test lung. An initial test of C0₂ production qualitatively demonstrated that the lung simulator behaved as expected. Since this project is in its initial stages, additional experimentation and model refinement is necessary for the simulator to accurately represent physiologic responses of a human lung.

Investigation Of Pathophysiologic Trends In Caucasian And Afro-American Hypertensives By Means Of Heart Rate Variability Recording During Upright Tilt-Table Testing, Jose F. Torrealba

Theses

The incidence of hypertension is more prevalent among the Afro-American population than the Caucasians and there is not a satisfactory explanation for this discrepancy.

Heart Rate Variability (HRV) has been demonstrated to reflect the relative activities of the sympathetic (SMP) and parasympathetic (PSMP) divisions of the autonomic nervous system (ANS).

This study consisted in comparing the HRV, as well as the blood pressure (BP) of four different groups during up-right tilt table testing. The subjects were grouped by age, gender, race and health condition. Analysis in time and frequency domain was applied to the data. In the frequency domain, the …

Farm Women's Roles And Their Experience Of Role Strain And Role Enhancement, Diane Dunn

Theses and Graduate Projects

Studies exploring farm women roles were limited to data of the 1980s utilizing the scarcity approach to role theory. This study expands on research by exploring farm women's roles today utilizing both the scarcity and expansion approaches. Random sampling of 81 farm women ages 26-78 were drawn from the Pipestone County Farm Service's mail-listing. Data was analyzed using JMP Statistical Data Analysis. The study revealed that farm women continued to fulfill roles involved with family, farming, and off-farm employment at rates similar/greater (employment) to those in the '80s. Findings also suggested that farm women experience both strains and enhancements from …
