Real-Time Measurements Of Space Potential In Magnetized Plasma Using A Baffled Langmuir Probe, Sean M. Finnegan Dec 2005

Real-Time Measurements Of Space Potential In Magnetized Plasma Using A Baffled Langmuir Probe, Sean M. Finnegan

Graduate Theses, Dissertations, and Problem Reports (ETD)

An electrostatic probe for real-time measurements of space potential in magnetized plasma is tested in fully ionized, barium, Q-machine plasma. The tungsten wire probe tip, oriented perpendicular to the magnetic field, is partially shielded by ceramic baffles (masks). Rotation of the probe about its cylindrical axis, changes the fraction of electrons that can reach the probe tip along the magnetic field, enabling the ratio between the electron and ion saturation currents to be adjusted without changing the probe bias. When optimally shielded, accurate, real-time measurements of space potential can be acquired.

Culvert Inventory And Effects On Fish Assemblages In A Central Appalachian Watershed, Ira O. Poplar-Jeffers Dec 2005

Culvert Inventory And Effects On Fish Assemblages In A Central Appalachian Watershed, Ira O. Poplar-Jeffers

Graduate Theses, Dissertations, and Problem Reports (ETD)

We surveyed 120 state-owned culverts within the upper Cheat River basin, West Virginia, and used a fish passage evaluation filter to quantify passage barriers. We quantified the length of stream and weighted potential brook trout recruitment area isolated by each culvert. We also sampled fish communities upstream and downstream of 24 culverts to quantify the impacts of culvert-related isolation on fish assemblages. We found 69% of culverts to be completely impassable. We determined that 17% of the stream length and 23% of weighted potential recruitment area in the study area were isolated by impassable culverts. We found that impassable culverts …

Size, Age Composition, And Upstream Migration Of American Eels At The Millville Dam Eel Ladder, Shenandoah River, West Virginia, Heather Hildebrand Dec 2005

Size, Age Composition, And Upstream Migration Of American Eels At The Millville Dam Eel Ladder, Shenandoah River, West Virginia, Heather Hildebrand

Graduate Theses, Dissertations, and Problem Reports (ETD)

Abundances of American eel (Anguilla rostrata) are declining along the east coast of the United States and Canada, possibly due to habitat loss and barriers to migration. In Atlantic coast watersheds, dams detain upstream migration of juveniles, and little is known about age class composition, age-length relationships, or environmental cues to upstream migration of yellow-phase eels. An eel ladder was installed on the Millville hydroelectric dam, lower Shenandoah River, WV, to facilitate and monitor the upstream movement of yellow phase eels. Daily length measurements (TL cm) and weights (g) were taken on eels using the ladder during three sampling periods; …

Thermal Stresses In The Superstructure Of Integral Abutment Bridges, Kevyn C. Mcbride Dec 2005

Thermal Stresses In The Superstructure Of Integral Abutment Bridges, Kevyn C. Mcbride

Graduate Theses, Dissertations, and Problem Reports (ETD)

Integral abutment bridges (IAB) have become a popular alternative to expansion joint bridges mainly due to their lower maintenance and repair costs. Although no specific guidelines exist for integral abutment bridge design, standards primarily used assume the volumetric changes of IAB under thermal loading occur free of constraint. This study examines the validity of this assumption and determines the effect of changing temperature on the state of stress in the superstructure of an IAB. The effect of changing thermal conditions on the Evansville Bridge in Preston County, West Virginia is investigated using an extensive bridge instrumentation system along with a …

Unconstrained Face Recognition For Law Enforcement Applications, Richa Singh Dec 2005

Unconstrained Face Recognition For Law Enforcement Applications, Richa Singh

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research work simulates the human visual cortex by using 2D log polar Gabor wavelet to extract the facial features. Scale and orientation independent convolution of face image with Gabor wavelet gives the features in the form of amplitude and phase. The proposed face recognition algorithm is invariant to frequency, scale, filter orientation, illumination, and contrast. We evaluated the recognition algorithm on four face databases namely FERET, CMU AMP, CMU PIE and Notre Dame Face databases. Experimental results show that using single image for training, phase feature based face recognition performs approximately 5% better than amplitude feature based face recognition.;Another …

Reducing False Rejection Rate In Iris Recognition By Quality Enhancement And Information Fusion, Mayank Vatsa Dec 2005

Reducing False Rejection Rate In Iris Recognition By Quality Enhancement And Information Fusion, Mayank Vatsa

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this thesis we propose a set of algorithms to reduce the false rejection rate of iris recognition. Even though high recognition accuracy is claimed for iris recognition algorithms, high false rejection rates cause the impediment in worldwide use of iris biometrics.;A novel iris segmentation algorithm for non-ideal iris images treating iris as an elliptical object is proposed. Further, quality of the extracted iris image is improved using SVM based enhancement algorithm. In this algorithm, selected enhancement algorithms globally enhance the iris image and the learning algorithm synergistically fuses local information from these intermediate enhanced images. 1D log polar Gabor …

Functional Evaluation Of Cytochrome P450 2d6 Allelic Isoforms, Weiyan Zhang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Human CYP2D6 is one of the most important human P450s based on the number of its drug substrates. It shows an extensive genetic polymorphism that influences its expression and function. There are more than 80 different CYP2D6 alleles and allelic variants that have been identified in human. However, only a part of alleles have been characterized with respect to enzyme activity and substrate specificity. In the first project, three alleles CYP2D6*24 (1297L), CYP2D6*27 (E410K) and CYP2D6*26 (I369T) were constructed and expressed. The enzymatic activities were evaluated by the metabolic rates for dextromethorphan O-demethylation and N-demethylation; codeine O-demethylation and N-demethylation. For …

Psychological Readiness: Is This Assessment Valuable To Athletic Trainers In Understanding Athletes' Adherence And Compliance, Damien Clement Dec 2005

Psychological Readiness: Is This Assessment Valuable To Athletic Trainers In Understanding Athletes' Adherence And Compliance, Damien Clement

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite the many documented psychological reactions athletes experiences as a result of athletic injuries, very little, if any psychological assessment is being done to evaluate their readiness to embark on their rehabilitation. Consequently, the purpose of this study was to determine if psychological readiness influences athletes' adherence and compliance to their rehabilitation programs. A secondary purpose was to determine the impact psychological readiness had on perceived versus actual completion rates of rehabilitation programs. Injured college student athletes' (N=70) psychological readiness were assessed (using the transtheoretical model of behavior change 10) to determine its effect on compliance, adherence rates and perceived …

The Behavioral Functions Of Stimuli Signaling Transitions Across Rich And Lean Schedules Of Reinforcement, Jessica B. Long Dec 2005

The Behavioral Functions Of Stimuli Signaling Transitions Across Rich And Lean Schedules Of Reinforcement, Jessica B. Long

Graduate Theses, Dissertations, and Problem Reports (ETD)

The present experiment was designed to assess whether stimuli correlated with rich and lean fixed-ratio schedule components would function as conditioned reinforcers and conditioned punishers, respectively. Pigeons responded on a mixed schedule with fixed-ratio components leading to large or small food reinforcers. Pecks on either of two observing keys converted the mixed schedule to a multiple schedule by turning on a color associated with the current component. The stimulus consequences of the observing responses were manipulated across conditions. Pecks on one observing key produced the rich stimulus and the lean stimulus whereas pecks on the other observing key produced only …

Properties Of Chain Programs Over Difference Constraints, John E. Argentieri Dec 2005

Properties Of Chain Programs Over Difference Constraints, John E. Argentieri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Chain Programming is a restricted form of linear programming in which there exists a total ordering over the program variables. In other words, the constraints x1 ≤ x 2 ≤ ... ≤ xn are either implicitly or explicitly part of the constraint system. At the present juncture, it is not clear whether an arbitrary Chain Program is easier to solve than a linear program, either asymptotically or computationally. This thesis presents a variety of interesting properties pertaining to the case in which a Chain Program is constituted entirely of difference constraints. Deciding the feasibility of a system of difference constraints …

The Influence Of Beaver Impoundments On Vegetative Composition, And Modeling Habitat Suitability As A Tool For Wildlife Management And Conservation, Jerry Leanne Bonner Dec 2005

The Influence Of Beaver Impoundments On Vegetative Composition, And Modeling Habitat Suitability As A Tool For Wildlife Management And Conservation, Jerry Leanne Bonner

Graduate Theses, Dissertations, and Problem Reports (ETD)

Beavers (Castor canadensis) can have dramatic effects on vegetative communities through impounding streams and wetlands. These alterations may influence rare plant species where beaver create ponds. We found that the youngest and oldest beaver ponds in Canaan Valley, West Virginia, USA had similar species richness. Rare plant species occurred most in oldest ponds, although no significant differences were detected. Species composition around ponds was found to be different between areas influenced by ponds versus those not affected, creating more obligate wetland communities when influenced by beaver. This information should be incorporated into management decisions when rare plant species conservation is …

A Study Of Ion Acceleration, Asymmetric Optical Pumping And Low Frequency Waves In Two Expanding Helicon Plasmas, Xuan Sun Dec 2005

A Study Of Ion Acceleration, Asymmetric Optical Pumping And Low Frequency Waves In Two Expanding Helicon Plasmas, Xuan Sun

Graduate Theses, Dissertations, and Problem Reports (ETD)

This work concerns measurements of parallel ion flow, optical pumping, and low frequency waves in expanding plasmas generated by two different helicon plasma sources. The measurements confirm numerical predictions of the formation of a current-free double layer in a region of diverging magnetic field. With laser-induced fluorescence (LIF), the double layer structure in both helicon plasma sources was investigated through measurements of the bulk parallel ion flow speed. Both double layers have a total potential drop of 3-4 kTe and length scales smaller than ion-neutral mean-free-path. A stronger double layer, with a potential drop of ∼ 6kTe , was created …

An Ecological Study Of Panax Quinquefolius In Central Appalachia: Seedling Growth, Harvest Impacts And Geographic Variation In Demography, Martha E. Van Der Voort

Graduate Theses, Dissertations, and Problem Reports (ETD)

American ginseng (Panax quinquefolius L.) is a long-lived, slow-maturing understory perennial herb found in eastern North American forests. The economic value of P. quinquefolius on the world market has remained strong for nearly 300 years. It has high economic and social value in the central Appalachians as well. Persistent harvest of ginseng combined with habitat loss has reduced populations in the wild, threatening the future of the species and its continued harvest. American ginseng was placed on the CITES Appendix II list in 1973 due to population declines. These concerns led to a series of studies investigating the population dynamics …

Automated Dental Identification: A Micro-Macro Decision-Making Approach, Diaa Eldin M. Nassar Dec 2005

Automated Dental Identification: A Micro-Macro Decision-Making Approach, Diaa Eldin M. Nassar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Identification of deceased individuals based on dental characteristics is receiving increased attention, especially with the large volume of victims encountered in mass disasters. In this work we consider three important problems in automated dental identification beyond the basic approach of tooth-to-tooth matching.;The first problem is on automatic classification of teeth into incisors, canines, premolars and molars as part of creating a data structure that guides tooth-to-tooth matching, thus avoiding illogical comparisons that inefficiently consume the limited computational resources and may also mislead the decision-making. We tackle this problem using principal component analysis and string matching techniques. We reconstruct the segmented …

Resource-Based View Of Knowledge Management For Competitive Advantage, Leila A. Halawi, Jay E. Aronson, Richard V. Mccarthy Dec 2005

Resource-Based View Of Knowledge Management For Competitive Advantage, Leila A. Halawi, Jay E. Aronson, Richard V. Mccarthy

Publications

We are not only in a new millennium, but also in a new era: the knowledge era. Sustainable competitive advantage is dependent on building and exploiting core competencies. The resource-based view (RBV) of the firm defines a strategic asset as one that is rare, valuable, imperfectly imitiable and non-substitutable. Knowledge is seen as a strategic asset with the potential to be a source of competitive advantage for an organization. In this paper, we provide a model that examines how and why knowledge management (KM) can be sued to create competitive advantage from the RBV of the firm.

Degree Of Sedentarization Affects Risks And Conflicts For The Waso Boran In Northern Kenya, D. Layne Coppock, Abdullahi D. Jillo, Mark N. Mutinda, Abdilla A. Aboud

Environment and Society Faculty Publications

The Waso Borana have lived for over a century in northern Kenya. In the last few decades, however, their ability to maintain their traditions has been severely challenged. Here we report survey results from 540 households in Isiolo District, stratified among three groups differing in terms of lifestyle: sedentary, semi-sedentary, and mobile. In some cases these groups vary with respect to important perceived risks, causes of natural-resource related conflict, and possible solutions to conflict. For example, sedentary respondents often noted concerns over land tenure problems, human diseases, and political incitement. Mobile respondents, in contrast, often noted primary concerns over drought, …

Asian Indian Perceptions Of Normality: A Qualitative Study, Mohammed S. Lodhi Khan Dec 2005

Asian Indian Perceptions Of Normality: A Qualitative Study, Mohammed S. Lodhi Khan

Theses and Dissertations

Normal mental health has always been defined from a Euro-centric worldview that excludes non-Westem cultures. In fact, what is normal is biased against non-Westem cultural ideals that influenced the definition of mental health. The difference between Eastern and Western cultural values suggest that the two cultures may also have differing views on the definition of normal mental health. The most commonly accepted definition of normality currently in use in the West is based on the models of health, utopia, average, transactional systems, and pragmatism. However, people from non-European cultures, such as Asian Indians, may not be represented by these current …
