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.

Workforce Investment Act Services: Effect On Dislocated Worker Reemployment, Martha A. Walker

Educational Leadership & Workforce Development Theses & Dissertations

The effect of WIA services on the gainful reemployment of Virginia's dislocated workers was explored using a mixed method, non-experimental, ex post factoresearch design. Analysis of variance with follow-up post hoc tests probed for statistically significant differences in hourly reemployed wage and weeks dislocated determined by (a) WIA service level, (b) impact of training, (c) characteristics of training completers and non-completers, and (d) impact of dislocated worker characteristics. Qualitative methods were used to search for trends and patterns defined by the perceptions of both dislocated workers and employers.

Between 2000 and 2004, Virginia's dislocated workers averaged 1.5 years of …

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 …

Effects Of Elevated Atmospheric Co₂ On Scrub-Oak Root Carbon Pools And Soil Microbial Processes, Alisha Lea Pagel Brown

Biological Sciences Theses & Dissertations

The levels of atmospheric CO₂ are rising and this affects the growth of plants and the ecosystems in which they reside. Plants take up additional C from the atmosphere and have potential to sequester C in the soil. I investigated the sequestration of C belowground and the microbial processes that control C retention in the soil. This study was conducted in a Florida scrub-oak ecosystem, where CO₂ levels have been elevated to twice ambient since 1996 in open top chambers. There were eight replicates of ambient CO₂ chambers and eight replicates of twice-ambient CO₂ levels. The …

Template-Based Metadata Extraction For Heterogeneous Collection, Jianfeng Tang

Computer Science Theses & Dissertations

With the growth of the Internet and related tools, there has been a rapid growth of online resources. In particular, by using high-quality OCR (Optical Character Recognition) tools it has become easy to convert an existing corpus into digital form and make it available online. However, a number of organizations have legacy collections that lack metadata. The lack of metadata hampers not only the discovery and dispersion of these collections over the Web, but also their interoperability with other collections. Unfortunately, manual metadata creation is expensive and time-consuming for a large collection, and most existing automated metadata extraction approaches have …

Dissertations and Theses @ UNI

The increasing number of one-on-one paraprofessionals has intensified interest in issues regarding their appropriate employment. The purpose of this qualitative case study was to determine the perceptions of a paraprofessional assigned to provide one-on-one supports for a student with special needs regarding how the need for paraprofessional assistance was determined, who participated in the selection process, necessary qualifications for employment, assigned roles and responsibilities, training opportunities, and supervision practices. Data was collected through three semi-structured interviews with a one-on-one paraprofessional. Additional themes identified through data analysis included barriers to job performance, job satisfaction, negatives of being a one-on-one paraprofessional, and …

Functional Behavioral Assessment : A New Model For Interviewing, Shelley K. Schafer

Dissertations and Theses @ UNI

The factors which affect how children learn are as varied as the individual students within any given classroom. These factors can affect not only the academic resilience of the student, but their behavior as well. Problem behaviors that create substantial amounts of tension in the classroom can inhibit the academic success of an individual child, as well as the performance of his or her peers. Some students do not have the appropriate behavioral repertoires necessary to cope with the many academic and social expectations of attending school. The purpose of the current study is to develop and assess the effectiveness …

Processing And Characterization Of High Performance Structural Nanocomposites, Dennis C. Working

Mechanical & Aerospace Engineering Theses & Dissertations

Carbon nanotubes are considered to be a revolutionary material breakthrough due to their unique combination of properties. While many applications for SWCNTs have been projected, realization of these potential uses have been hampered by the high cost of limited supplies of high quality SWCNTs and the difficulty in the development of a suitable processing method that does not damage the filler thus diminishing the desirable properties of this material. In spite of these technical challenges, their potential to enable the fabrication of multifunctional materials is being investigated in earnest. The goal of this thesis is to investigate the feasibility of …

Caves And Speleogenesis At Blomstrandsøya, Kongsfjord, W. Spitsbergen, Stein-Erik Lauritzen

International Journal of Speleology

Blomstrandsøya, at Kongsfjord (78° 57’N), Spitsbergen, is within the high arctic, a completely permafrozen zone. The bedrock consists of Paleozoic marbles and has yielded a surprising amount of karst features. Early phases of hydrothermal, possibly Caledonian, speleogenesis and subsequent Devonian karstification with redbed deposits is well documented. 62 active seacaves, and more than 30 relict karst caves were found in the coastal cliffs and in escarpment faces around the island. All caves have very limited extent; they are either quite short, like most of the active sea caves, or they are soon choked by frozen sediments and ground ice after …

The Flood Frog: An Autonomous Wireless Device For Flood Detection And Monitoring, Valerio Plessi

Masters Theses

"Accurate real time monitoring is gaining critical importance in a broad range of domains. Of particular interest to this research is the development of monitoring and detection systems for environmental and structural phenomena. Transportation infrastructures, in particular bridges, provide examples for both categories. Flooding of low water bridges is one example of rapidly evolving environmental phenomena, while stress and vibration are structural phenomena in need of monitoring.

Early warning and advanced preparation for emergency are two of the most effective lines of defense against catastrophic events, where real time monitoring can facilitate containment and recovery efforts. The operating environment of …

The Relationship Of Undergraduate Cognitive Development And Academic Advising Preference At Two Small, Private, Liberal Arts Colleges, Vicki Van Vark Edelnant

Dissertations and Theses @ UNI

Though developmental advising has been widely accepted for some time, some recent studies have questioned whether this approach to advising is universally appropriate. The primary purposes of this study were to determine what, if any, relationship exists between students' preference for academic advising approach and either their level of cognitive development or their gender.

One hundred seventy-three students at two small, private, liberal arts colleges completed the Academic Advising Inventory (AAI) to assess their advising preferences and the Measure of Epistemological Reflection (MER) to measure cognitive development levels. A correlation coefficient of scores on the AAI and the MER indicated …

The Varieties Of Aesthetic Disinterestedness, Norman Kreitman

Contemporary Aesthetics (Journal Archive)

Disinterestedness, a comparatively recent concept in aesthetics, is commonly held to be one of the characteristics of an appropriate response to art, but can be understood in a number of senses. Three varieties are distinguished: a strong form which confines attention exclusively to the internal relations of the work of art; a moderate variety which links internal and external features of the work but solely within the cognitive domain; and a weak form which permits the appreciator to draw on a wide range of external referents but proscribes purely idiosyncratic responses. An illustration is given of the confusion which can …

Exploring Intersectionality In Education: The Intersection Of Gender, Race, Disability, And Class, Amy J. Petersen

Dissertations and Theses @ UNI

The purpose of this study was to explore the intersection of gender, race, disability, and class within education. Specifically, I examined the educational experiences of African American women labeled with a disability and from a disadvantaged socio-economic class. Employing qualitative methodology and methods, I interviewed four adult African American women from disadvantaged socio-economic groups to gain a deeper understanding of their lived educational experiences.

The story that emerged from this research was each participant's strength. Their stories revealed that each woman persistently and continually engaged in the world around them in order to negotiate, evade, and resist the dominant ideology …

School-Wide Positive Behavior Supports : An Evaluation Of An Elementary School Program, Lisa Andreasen

Dissertations and Theses @ UNI

The outcomes of a school-wide positive behavior support program at a rural elementary school were evaluated to determine the effects of a school-wide program on the behavior of students. A program evaluation was conducted using student office referrals that were collected over a six year period. The results indicated that student office referrals significantly decreased from Year 1 to Year 6 and that specific behaviors of aggression and inappropriate language also decreased significantly from Year 1 to Year 6. Data were investigated to indicate trends in total office referrals by gender, grade, month, location, and problem behavior.

Learning To Learn: Undoing The Gordian Knot Of Development Today, Charles F. Sabel, Sanjay G. Reddy

Faculty Scholarship

The deep flaw of existing approaches to development is their dirigisme: the assumption, common to nearly all development theory, that there is an expert agent that already sees the future. A common thread connects the emergent alternatives to development orthodoxy: the enhancement of the conditions of individual and collective learning. This approach to development highlights the existence of unresolved problems and the necessity of problem solving in every sphere. The enhancement of the conditions of learning can be the key to improving performance, resolving deadlocks, and overcoming blockages, at every level at which common dilemmas and collective problem solving occur …

Fostering Imaginative Expression In Elementary Art Students: A Descriptive Study Of Teacher Strategies, Julia Robinson Bargo

Theses and Dissertations

The students in my elementary art classes did not seem to be creating for themselves. They seemed to have the understanding there was only one correct answer in art class, and the art teacher knew what that answer was. By way of research I have found ways to create an atmosphere in my art room that promotes imagination and self expression in children, thus fostering a free and creative reaction from my students. Through understanding how and why one uses their imagination, an art teacher can enhance a student's ability to build and use his or her knowledge base. I …

Erc Accumulation And Premature Aging: An Investigation Of The Deletion Of Ash1 In The Budding Yeast Saccharomyces Cerevisiae, Ranor C B Basa

Pomona Senior Theses

This thesis concerns the asymmetric mechanism by which the "molecular aging clock" is reset in the budding yeast Saccharomyces cerevisiae, which is of great interest considering that many organisms' cells--including human stem cells--undergo this process. When yeast divides, it ages a generation, while daughter cells begin life at generation zero. One theory surrounding this process in yeast is the extrachromosomal rDNA circle (ERC) aging theory. ERCs are generated spontaneously in mother cells as they age, and thus accumulate exponentially in older cells. Daughter cells from young mothers benefit from asymmetric aging, but as mothers age, they produce daughters that …

Technical Change And Us Economic Growth: The Interwar Period And The 1990s, Alexander J. Field

Economics

Multifactor productivity growth in the U.S. economy between 1919 and 1929 was almost entirely attributable to advance within manufacturing. Distributing steam power mechanically over shafts and belts required multistory buildings for economical operation. The widespread diffusion of electric power permitted a shift to single story layouts in which goods flow could be optimized around work stations powered by small electric motors. Within this framework, as well as opportunities to produce a variety of new products, economies of scale and learning by doing permitted rapid and across the board gains in manufacturing productivity. The sector contributed 83 percent of the 2.02 …

Survey Research In Finance: Views From Journal Editors, H. Kent Baker, Tarun K. Mukherjee

Department of Economics and Finance Working Papers, 1991-2006

We survey editors from 15 "core" and 35 "non-core" finance journals to learn their views about specific issues involving survey research. Based on responses from 25 editors, none of their journals has an established policy involving the publication of survey research. The evidence shows that survey-based manuscripts typically go through the same review process as other manuscripts. However, editors of "core" versus "non-core" journals have mixed views about the role that survey research should play in the finance literature. The editors provide their views about the strengths and weaknesses of survey research as well as topic areas that would benefit …
