Effects Of A Manikin On The Capture Efficiency And Protection Efficiency Of A Small Rectangular Hood, Brian Scott Geissler
Effects Of A Manikin On The Capture Efficiency And Protection Efficiency Of A Small Rectangular Hood, Brian Scott Geissler
Graduate Theses, Dissertations, and Problem Reports (ETD)
The primary indicator of capturing hood effectiveness is widely assumed to be the "capture velocity" measured normal to the center of the hood face, at the furthest location of the contaminant source. The velocity required at this distance (Vx) is thought to correspond to the appropriate flow (Q) required to capture the contaminant. The adequacy of Vx as a surrogate for hood effectiveness has long been poorly understood and has been little studied. Few considerations of potentially disruptive parameters, such as draft velocity, hood orientation, and operator presence are made during the design phase.;In this study, an anatomically correct heated, …

Effects Of Systematic Sleep Fragmentation On Tolerance And Threshold In A Pressure Pain Task: Associations With Sustained Attention, Margeaux Marissa Gray
Effects Of Systematic Sleep Fragmentation On Tolerance And Threshold In A Pressure Pain Task: Associations With Sustained Attention, Margeaux Marissa Gray
Graduate Theses, Dissertations, and Problem Reports (ETD)
Purpose: Pain is amplified following partial sleep deprivation. Pain has not been evaluated after sleep interruption, when total sleep time is preserved. Sleep interruption, also called sleep fragmentation, is ecologically relevant because it is caused by common sleep disorders such as Obstructive Sleep Apnea [OSA], Upper Airway Resistance Syndrome [UARS] and Periodic Limb Movements Disorder [PLMD]. The Sleep Continuity Hypothesis posits that the restorative effects of sleep are related to sleep quality in addition to quantity. With this study, my goal was to evaluate whether sleep fragmentation affected pain threshold and/or tolerance by systematically fragmenting the sleep of otherwise healthy …
Sense Of Place And Belongingness In Outdoor Orientation Programming, John Greene
Sense Of Place And Belongingness In Outdoor Orientation Programming, John Greene
Graduate Theses, Dissertations, and Problem Reports (ETD)
Researchers utilized a quasi-experimental design to assess outcomes associated with outdoor orientation programming. Researchers measured quantitative variables associated with sense of place and belongingness. Literature suggests a theoretical association between individuals' relationship to place and their sense of belonging to others. To test these variables researchers created a curriculum designed to facilitate sense of place for students participating in week long outdoor orientation programs. A sample (n=228) of incoming students to West Virginia University participating in outdoor orientation trips was split into an experimental group and a control group. The control group received a standardized curriculum designed to successfully transition …
More Than Just Attendance: Individualistic Versus Collective Religious Socialization On Religious Change, Caitlin Halligan
More Than Just Attendance: Individualistic Versus Collective Religious Socialization On Religious Change, Caitlin Halligan
Graduate Theses, Dissertations, and Problem Reports (ETD)
With the recent rise in individuals not identifying with a religion, now is a prime time to research disaffiliation. Using data from the National Study of Youth and Religion, the present study examines whether or not collective religious participation in early adolescence, above and beyond individualistic religious participation, reduces the likelihood of disaffiliation in young adulthood. The results show that those who attended a religious youth group in early adolescence were less likely to disaffiliate in early adulthood than those who did not attend. Youth group seems to have a unique role in retaining youth involvement in the church.

Teaching Without A Net: Experiencing Mandatory Curriculum Change, Stephen Ross Higgins
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation reports a qualitative study that explored the reconstructed narratives of 4 West Virginia 7th grade social studies teachers. A methodology informed by narrative inquiry guided the research design, including the methods for data collection and data analysis. Two questions served as guideposts throughout the research process: What do the stories of the participants tell us about the ways in which teachers engage as developers of curriculum when curriculum change is mandated? In what ways did their stories of implementing a mandated change impact their professional identities? To explore these questions, I conducted 3 semi-structured interviews with each participant. …
Between A Bear And An Eagle: Soviet Arms And The U.S. Response In Peru, William Horacek
Between A Bear And An Eagle: Soviet Arms And The U.S. Response In Peru, William Horacek
Graduate Theses, Dissertations, and Problem Reports (ETD)
This research looks at the left-leaning military government of Juan Velasco Alvarado of Peru ruled from 1968 to 1975. This government embarked on a crusade to modernize Peru through a series of reforms and changes in Peruvian foreign policy. The United States responded with non-overt economic pressure, and the ending of military sales to Peru. Peru bought weaponry from the Soviet Union against the wishes of the United States in 1973, and this resulted in a more conciliatory foreign policy from the United States towards the Andean nation. The shifting foreign policy is the opposite of how historians have characterized …

Dynamic Model And Estimator Development For A Smart Refractory Brick With Embedded Wireless Sensors For Gasifier Applications, Qiao Huang
Graduate Theses, Dissertations, and Problem Reports (ETD)
The operating temperature is one of the most important variables for gasifier operation. A higher temperature can shorten the service life of the refractory lining. A lower temperature can reduce the extent of carbon conversion and disrupt the flow of molten slag in a slagging gasifier. Therefore temperature is one of the most important variable in a gasifier. In slagging gasifiers, molten slag can penetrate into the refractory lining leading to refractory spallation, undesired downtime, and costly replacement. Even though the temperature and extent of slag penetration are extremely important for the gasifier operation, they cannot be measured reliably by …
Afis Based Likelihood Ratios For Latent Fingerprint Comparisons, Shreya Sateesh Kamath
Afis Based Likelihood Ratios For Latent Fingerprint Comparisons, Shreya Sateesh Kamath
Graduate Theses, Dissertations, and Problem Reports (ETD)
Latent fingerprints are one of the most common pieces of evidence found on a crime scene and represent accidental or unintentional prints collected as part of a criminal investigation. They are caused when the friction ridge skin comes in contact with a surface, and thus requires the use of chemical processing to be visualized with the naked eye. The comparison and identification of fingerprints depends on various factors such as the substrate quality, surface, duration, environmental factors and examiner experience. These factors can result in reduced clarity or content, and can even cause distortions as compared to a fingerprint taken …

Revolutionary Pedagogy: A Historical Perspective On Improvising In Beethoven, Julia Kinderknecht
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation will investigate the historical significance and modern application of Beethoven's improvisations in performance, first by observing what we know through primary sources and eye-witness accounts, then by considering the reasons for the absence of improvisation in modern performance practice and the steps that could be taken towards reincorporating classical improvisation into modern pedagogy, and finally by offering historically-based improvisation exercises and written-out examples of improvisations in Beethoven's works to benefit modern pianists.
Amplifier Design For Underground Anomaly Detection Using Naturally Occurring Ultra Low Frequencies, Dakota James Kirby
Amplifier Design For Underground Anomaly Detection Using Naturally Occurring Ultra Low Frequencies, Dakota James Kirby
Graduate Theses, Dissertations, and Problem Reports (ETD)
Most high-frequency signals are unable to penetrate the Earth's surface and lower frequencies have a much higher chance of penetrating the surface. Ultra-low frequencies can be used to penetrate the Earth's crust, but the frequency and background noise are a large problem that prevents from detecting these low frequency signals. This thesis describes the design for a small and lightweight low-frequency amplifier that can receive low voltage signals and amplify them to a level that could be used to do further analysis. The proposed amplifier design was capable of handling inputs as low as 1 muV and amplifying them to …
Rehabilitation In The Punitive State: An Oxymoron? An Examination Of Rehabilitation And Punitive Practices In The United States, Jeri Kirby
Graduate Theses, Dissertations, and Problem Reports (ETD)
The extent and nature of incarceration has changed dramatically over the last 40 years in the United States. From 1980 to 2007, the American incarceration rate increased by 1,100 percent (BJS 2008). Much of this incarceration boom can be linked to the War on Drugs (WOD) and the punitive sentencing policies that developed from it. Understanding these punitive effects on individuals and communities and the challenges of prisoner re-entry requires us to consider the many levels of punishment that play a role in the United States correctional policies. Past research has considered the impact of the WOD policies on many …

Data Conversion Within Energy Constrained Environments, Brandon M. Kelly
Graduate Theses, Dissertations, and Problem Reports (ETD)
Within scientific research, engineering, and consumer electronics, there is a multitude of new discrete sensor-interfaced devices. Maintaining high accuracy in signal quantization while staying within the strict power-budget of these devices is a very challenging problem. Traditional paths to solving this problem include researching more energy-efficient digital topologies as well as digital scaling.;This work offers an alternative path to lower-energy expenditure in the quantization stage --- content-dependent sampling of a signal. Instead of sampling at a constant rate, this work explores techniques which allow sampling based upon features of the signal itself through the use of application-dependent analog processing. This …

Forest inventory information is a principle driver for forest management decisions. Information gathered through these inventories provides a summary of the condition of forested stands. The method by which remote sensing aids land managers is changing rapidly. Imagery produced from unmanned aerial systems (UAS) offer high temporal and spatial resolutions and have added another approach to small-scale forest management. UAS imagery is less expensive and easier to coordinate to meet project needs compared to traditional manned aerial imagery. This study focused on producing an efficient and approachable work flow for producing forest stand board foot volume estimates from UAS imagery …
Financial Decision Making, Price, And Consumer Financial Well-Being: A Multiple Methodology Inquiry Of The Cognitions, Emotional Coping Responses, And Brand Measures In The Healthcare Service Industry, Joshua D. Dorsey
Graduate Theses, Dissertations, and Problem Reports (ETD)
Article 1: Financial bankruptcy, particularly those as a result of healthcare expenses, has become a pervasive issue in the United States. This article examines a basic premise for the research, that healthcare is not viewed, by consumers, consistently with other exchanges, leading to detachment and disengagement within the purchase experience (e.g., a lack of price searching and price comparison behaviors) and disadvantageous consequences for financial well-being. Subsequently, the studies test cognitive (i.e., knowledge structures) and emotional constructs (i.e., emotion regulation), with a between-subjects experimental methodology (three studies), that may further unfurl the decision process for healthcare consumers. Contributions to the …

Analysis Of Model-Aided Navigation Of Unmanned Aerial Vehicles, Stephane D'Urso
Graduate Theses, Dissertations, and Problem Reports (ETD)
To overcome the rapid and unbounded error growth of low-cost Inertial Navigation Systems (INS), aircraft localization methods commonly compensate for Inertial Measurement Unit (IMU) sensor errors by integrating them with Global Positioning System (GPS) measurements via a Kalman Filter. However, over the past decade, the potential of GPS jamming or even spoofing GPS signals has forced the research community to focus on the development of GPS-denied navigation technologies. Among the GPS-denied techniques, one approach that has been considered is the use of a Vehicle Dynamic Models (VDM) to reduce the rate at which an INS becomes unusable. As such, this …

Syntheses Of Functionalized Cycloparaphenylenes, Furan-Containing Cycloparaphenylenes, And Related Thiophene-Containing Fused Carbon Nanohoop, Behzad Farajidizaji
Graduate Theses, Dissertations, and Problem Reports (ETD)
Synthetic pathways for preparing furan-containing cycloparaphenylenes (CPPs) bearing 10, 12, and 15 aromatic units in the macrocyclic ring structures were developed. Several important steps used in these syntheses are the Suzuki--Miyaura cross-coupling reaction between the L-shaped building block and 2-furanylboronic ester the nickel-mediated homocoupling reaction to incorporate two and three 2,2'-bifuran-5,5'-diyl units into functionalized [6]- and [9]cycloparaphenylene (CPP) precursors. Oxidative aromatization of the precursors with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) under mild conditions led to the formation of fully aromatized furan-containing cycloparaphenylenes (CPPs).;The Diels--Alder reaction between the parent benzyne or 3,6-dimethoxybenzyne with furan-2,5-diyl units incorporated into functionalized [8]CPP macrocycle followed by reductive deoxygenation …
Comparison Of Methods Of Measuring Electronic Cigarette Puff Topography, Nicholas Felicione
Comparison Of Methods Of Measuring Electronic Cigarette Puff Topography, Nicholas Felicione
Graduate Theses, Dissertations, and Problem Reports (ETD)
To evaluate properly the potential benefits and harms of electronic cigarettes (ECIGs), it is important to evaluate how individuals puff from an electronic cigarette, or their puff topography. This measure, which includes indices of puff number, duration, volume, interpuff interval, and flow rate, can be used to predict exposure to toxicants including nicotine. Puff topography has been studied extensively for cigarette smokers, but not ECIG users. The studies that have involved electronic cigarette topography measurement have done so using devices that have not been thoroughly validated or proven reliable. Thus, the purpose of this study was to evaluate methods of …
Evaluating Treatment Integrity Failures During Timeout From Play, Apral P. Foreman
Evaluating Treatment Integrity Failures During Timeout From Play, Apral P. Foreman
Graduate Theses, Dissertations, and Problem Reports (ETD)
Timeout is an effective behavior-reduction strategy with considerable generality. There are several recommendations about how to implement timeout. However, little research has investigated how timeout is implemented under natural conditions, or how timeout-implementation errors impact its effectiveness. Thus, our study attempted to address two aims. The first aim was to observe how teachers implemented timeout with their students. To address this aim (Experiment 1), we completed naturalistic observations of teachers who were implementing timeout during play. We collected data on how frequently the teachers implemented timeout following problem behavior (omission integrity), and how frequently teachers implemented timeout following responses not …

Complexity Aware C-Ran Scheduling For Ldpc Codes Over Bec, Kyle Gordon Whetzel
Graduate Theses, Dissertations, and Problem Reports (ETD)
Effective transmission of data over a noisy wireless channel is a vital part of today's high speed technology driven society. In a wireless cell network, information is sent from mobile users to base stations. The information being transmitted is protected by error-control codes. In a conventional architecture the signal processing, including error-control decoding, is performed locally at each base station. Recently, a new architecture has emerged called Centralized Radio Access Network (C-RAN), which involves the centralized processing of the signals in a computing cloud. Using a computing cloud allows computational resources to be pooled, which improves utilization and efficiency. When …
