Robustness And Control Of A Magnetically Levitated Transportation System, Grzegorz Oleszczuk

Mechanical & Aerospace Engineering Theses & Dissertations

Electromagnetic suspension of Magnetic Levitation Vehicles (Maglev) has been studied for many years as an alternative to wheel-on rail transportation systems. In this work, design and implementation of control systems for a Maglev laboratory experiment and a Maglev vehicle under development at Old Dominion University are described. Both plants are modeled and simulated with consideration of issues associated with system non-linearity, structural flexibility and electromagnetic force modeling. Discussion concerning different control strategies, namely centralized and decentralized approaches are compared and contrasted in this work. Different types of electromagnetic non-linearities are considered and described to establish a convenient method for modeling …

Development Of A Nonlinear Estimator-Based Model Of Pilot Performance During Brownout Conditions, Karl Ulrich Schultz

Mechanical & Aerospace Engineering Theses & Dissertations

During conditions of visual occlusion, pilots are forced to rapidly adapt their scan to accommodate the new observable states via instruments rather than the visual environment. During this transition, the provision of aircraft state information via other than visual modalities improves pilot performance presumably through the increase in situational awareness provided immediately following the visual occlusion event.

The Tactile Situational Awareness System (TSAS) was developed to provide continuous position information to the pilot via tactile rather than visual means. However, as a low-resolution display, significant preprocessing of information is required to maximize utility of this new technology.

Assimilating Non-Probabilistic Assessments Of The Estimation Of Uncertainty Bias In Expert Judgment Elicitation Using An Evidence Based Approach In High Consequence Conceptual Designs, Colin K. S. Barrows

Engineering Management & Systems Engineering Theses & Dissertations

One of the major challenges in conceptual designs of complex systems is the identification of uncertainty embedded in the information due to lack of historic data. This becomes of increased concern especially in high-risk industries. This document reports a developed methodology that allows for the cognitive bias, estimation of uncertainty, to be elucidated to improve the quality of elicited data. It consists of a comprehensive literature review that begins by defining a 'High Consequence Conceptual Engineering Environment' and identifies the high-risk industries in which these environments are found. It proceeds with a discussion that differentiates risk and uncertainty in decision-making …

A Longitudinal Investigation Of Cognitive Predictors Of Self-Care Behaviors In Youth With Type I Diabetes, Michelle Marie Greene

Theses and Dissertations

Cross-sectional research of youth with type I diabetes has demonstrated that rote and working memory predict blood glucose monitoring (BGM) and carbohydrate consumption, respectively; however, to date, no longitudinal follow-up studies exist. Rote and working memory subtests from well-standardized memory measures, along with a problem-solving and executive functioning measures were administered to 118 youth with type I diabetes, aged 9-16 in two waves of data collection (mean interval = 2.07 years). Diabetes care behaviors were assessed through the 24-hour Diabetes Interview. This study was the first to document longitudinal prediction of BGM by rote memory and fat consumption by working …

How Promotions Effect Consumer Purchases, Justin D. White

Theses and Dissertations

Rational choice theory provides a blueprint for predicting individual behavior under the assumption that objectives and decisions are rationally identified and executed. Under certain conditions, actions reveal preferences and the ability to observe these preferences allows for the possibility to study the effects of subtle changes in individual constraints such as price and wealth affect preferences. For instance, recent work by Eckel and Grossman (2003), Davis, Millner and Reilly (2003), and Davis and Millner (2004) observe a preference for matching promotions over coupon rebates even when the two promotions types are strictly equivalent. An important question remaining is whether this …

Traits Of Writing, Traits Of Art, Michelle Ciancarelli Becker

Theses and Dissertations

A study was conducted of Introductory Art students to find if the six traits of writing as written by Spandel/Stiggins (1997) would have influence over a narrative painting when combined with the six traits of painting. Inconclusive findings were reported. Data difference between the treated and untreated class was less than one point. More research needs to be conducted to study transfer of knowledge from verbal to visual as well as from one curriculum to another with both curriculums teaching same material.

A Gis And Remote Sensing Based Analysis Of Impervious Surface Influences On Bald Eagle (Haliaeetus Leucocephalus) Nest Presence In The Virginia Portion Of The Chesapeake Bay, Jennifer M. Ciminelli

Theses and Dissertations

GIS (Geographic Information Systems) and remote sensing techniques were used to predict relationships between bald eagle nest presences and land type, distance to land type and impervious surface cover area. Data plots revealed bald eagle nest presence decreases in response to an increase in area of bareland; increases with an increase in area of forested land; decreases with an increase in distance (m) to shoreline, and decreases in response to an increase in area of impervious surfaces. Logistic regression models identified impervious surfaces as an indicator for bald eagle nest presence (P 24% as unsuitable. Unsuitable area covered 17.82% of …

Photochemical Applications To The Study Of Complexity Phospholipid Bilayer Environments, Christopher John Wohl Jr.

Theses and Dissertations

The physical and biophysical properties of a biological membrane model, phosphatidylcholine bilayers, were investigated using novel spiropyran/merocyanine molecular probes. The femtosecond to second dynamics of this system's photochemistry enabled bilayer viscosity and free volume to be studied over a broad time scale. Spiropyrans/merocyanines with different polarity were synthesized by changing the substitution of the indole moiety enabling determination of the trans-membrane properties of the bilayer. In addition, transient grating spectroscopy was used to study thermal energy transfer in phospholipid bilayers on a picosecond time scale.Femtosecond transient absorption spectroscopy was used to study the photo-induced spiropyran ring-opening and isomerization reactions that …

Statistical Methods And Experimental Design For Inference Regarding Dose And/Or Interaction Thresholds Along A Fixed-Ratio Ray, Sharon Dziuba Yeatts

Theses and Dissertations

An alternative to the full factorial design, the ray design is appropriate for investigating a mixture of c chemicals, which are present according to a fixed mixing ratio, called the mixture ray. Using single chemical and mixture ray data, we can investigate interaction among the chemicals in a particular mixture. Statistical models have been used to describe the dose-response relationship of the single agents and the mixture; additivity is tested through the significance of model parameters associated with the coincidence of the additivity and mixture models.It is often assumed that a chemical or mixture must be administered above an unknown …

The Roles Of Food And Predation In Shaping Adaptive And Maladaptive Behaviors In Postfire Bird Species, Bruce Andrew Robertson

Graduate Student Theses, Dissertations, & Professional Papers

Most animals live in rapidly changing environments, and within-individual phenotypic plasticity can allow populations to track sources of selection that often vary dramatically in time and space. However, if conditions change too rapidly, the cues animals use to track environmental changes may become uncoupled from the ultimately important factors with which they have been historically correlated. Animals relying upon proximal cues to guide their behaviors may, in novel environments, consistently make errors. When these errors occur within the context of choosing a habitat, the organism is said to be caught in an ‘ecological trap’. Herein, I develop a conceptual model …

There Is More To Vision Than Seeing Clearly, Dawn Cardinal, Genea Nannemann

Occupational Therapy Capstones

"Vision is not simply the ability to read a certain size letter at a distance of 20 feet. Vision is a complex and adaptable information gathering and processing system which collects, groups, analyzes, accumulates, equates, and remembers information" (American Optometric Association, 2005, p.1). The purpose of this project is to develop a parent/caregiver handbook that will educate parent/caregivers with children who have visual deficits and to benefit the Vision Therapy Project, which is located in Casper, Wyoming. This project is a non-profit organization dedicated to provide assistance and education to parents/caregivers with children in need of vision therapy. Information for …

Recreational Manual For Caregivers Of Individuals With Cerebral Palsy, Erica Bucher

Occupational Therapy Capstones

A brief literature review was conducted on cerebral palsy to gain general information and statistics. After reviewing the literature, it was noted that there is a significantly high number of children diagnosed with cerebral palsy each year. These individuals are at a high risk to experience the lack of opportunity for a wide choice of recreational activities. To understand the magnitude of the problem an extensive literature review was done on this topic. It was found that the lack of access and participation in independent recreational opportunities may lead to the development of dependent behavioral patterns, learned helplessness and depression. …

Giving All Children A Good Start To School: A Protocol In Defining Occupational Therapist's Role In School Readiness, Specifically In The Smart Program, Melissa Boll

Occupational Therapy Capstones

More children are entering school "not ready." Current research is showing that many "healthy" children are entering school not developmentally ready for formal learning. Based my own experiences working as a school occupational therapist for the past four years in rural area schools, this new trend is becoming more apparent. Teachers and other school professionals have increasing concerns over the numbers of children that seem "clumsy" or "awkward" compared to their peers. Children are expected to learn more than ever before upon entering school, the curriculum is no longer age-appropriate due to the pushing down of academics. Upon entrance to …

The Impact Of Financial Market And Resale Market On Firm Strategies, Zhiling Guo, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

The ever-increasing use of information technology (IT) in business transactions greatly expands firms? exposure to different electronic markets. This paper provides a framework to understand how firms can leverage different strategies across external financial markets and an internal resale market to improve overall profitability. We develop a model in which a group of risk-averse retailers sell a homogeneous product to their respective uncertain consumer markets. We study a scenario where an internal resale market can be constructed among the retailers and outside financial markets can be used to improve their ability to manage uncertainty. We identify strategies for retailers operating …

Model Checking Control Communication Of A Facts Device, Bruce M. Mcmillin, J. K. Townsend, David Cape

Computer Science Faculty Research & Creative Works

This paper concerns the design and verification of a realtime communication protocol for sensor data collection and processing between an embedded computer and a DSP. In such systems, a certain amount of data loss without recovery may be tolerated. The key issue is to define and verify the correctness in the presence of these lost data frames under real-time constraints. This paper describes a temporal verification that if the end processes do not detect that too many frames are lost, defined by comparison of error counters against given threshold values, then there will be a bounded delay between transmission of …

On Adaptive Testing In Orthogonal Saturated Designs, Daniel T. Voss, Weizhen Wang

Mathematics and Statistics Faculty Publications

Adaptive, size-a step-down tests are provided for the analysis of orthogonal saturated designs. The tests work effectively under effect sparsity, and include as special cases the individual nonadaptive tests of Berk and Picard (1991) and the simultaneous nonadaptive tests of Voss (1988). The approach is similar to that used by Wang and Voss (2003) to construct adaptive confidence intervals, but testing is simpler because one can use the same denominator for all statistics. Step-down tests also have a clear power advantage over simultaneous confidence intervals and analogous single-step tests, as is demonstrated theoretically and assessed via simulation.
