Unifying The Visible And Passive Infrared Bands: Homogeneous And Heterogeneous Multi-Spectral Face Recognition, Nnamdi C. Osia
Graduate Theses, Dissertations, and Problem Reports (ETD)
Face biometrics leverages tools and technology in order to automate the identification of individuals. In most cases, biometric face recognition (FR) can be used for forensic purposes, but there remains the issue related to the integration of technology into the legal system of the court. The biggest challenge with the acceptance of the face as a modality used in court is the reliability of such systems under varying pose, illumination and expression, which has been an active and widely explored area of research over the last few decades (e.g. same-spectrum or homogeneous matching). The heterogeneous FR problem, which deals with …

Graduate Theses, Dissertations, and Problem Reports (ETD)
The interstellar medium is the principal ingredient for star formation and hence, it is necessary to study the properties of the interstellar medium. Radio sources in our Galaxy and beyond can be used as a probe of the intervening medium. In this dissertation, I present an attempt to use radio transients like pulsars and fast radio bursts and their interactions with the environment around them to study interstellar medium. We show that radio emission from pulsars is absorbed by dense ionized gas in their surroundings, causing a turnover in their flux density spectrum that can be used to reveal information …

Prediction Of Maximum Scour Depth Using Scaled Down Bridge Model In A Laboratory, Rupayan Saha
Graduate Theses, Dissertations, and Problem Reports (ETD)
Recently, United States faced catastrophic flooding in West Virginia, Texas, Louisiana, Oklahoma, and Arkansas, and the flooding resulted in several bridge failures. Among them, Bridge scour is one of the main causes of many bridge failures, and leads to financial losses as well as loss of life. Since 1960, a lot of scour research has been completed and several estimation methods were already in the hand of hydraulic engineers. However, scouring is still a challenging topic. Currently, the issues of scour are once again rising because the occurrence of extreme weather events are expected to increase in frequency. Furthermore, current …
Representation And Policy Making: Women Participating In The U.S. House, Lauren M. Santoro
Representation And Policy Making: Women Participating In The U.S. House, Lauren M. Santoro
Graduate Theses, Dissertations, and Problem Reports (ETD)
Past research has established the link between descriptive and substantive representation (Swers 2002a) and has overwhelmingly focused on agenda setting behaviors and roll call voting (e.g., Swain 1993; Thomas 1994; Swers 2013). The first part of this dissertation focuses instead on deliberations within committee hearings, quite proximate to the law-making process, where legislators exhibit representational behavior. Do women participate in committee proceedings more so than men when they consciously seek to represent so-called "women's interests"? This chapter aims to explore this question by gathering data on House hearings considering the Family and Medical Leave Act and a bill considering the …
Investigation Of Plasma Exhaust Profile Manipulation Using Magnetic Fields, Bryan A. Shambaugh
Investigation Of Plasma Exhaust Profile Manipulation Using Magnetic Fields, Bryan A. Shambaugh
Graduate Theses, Dissertations, and Problem Reports (ETD)
Electric propulsion systems are known for having a high specific impulse but very low thrust. In the case of a hypersonic, compressible flow, altering the exhaust profile has the potential to alter the exhaust velocity thus changing the total thrust output. In this research, the magnetoplasmadynamic (MPD) effects of applying a toroidal magnetic field to an ionized exhaust plume were investigated to manipulate the exhaust profile of the plasma jet under near vacuum conditions. The project also endeavored to determine the efficacy of permanent magnets as a replacement for electromagnetic systems in rocket propulsion. Tests for this experiment were conducted …
Three Essays On Trade And Local Labor Markets, Sandeep Sharma
Three Essays On Trade And Local Labor Markets, Sandeep Sharma
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation studies the effect of trade on wage dispersion, crime rates and alcohol consumption at the local labor market level in the the U.S. The first chapter develops a new measure for skill to investigate the effects of offshoring on wages of three types of workers: high-skilled, medium-skilled, and low-skilled. I also look at the effect of offshoring on wages of offshorable occupations. Although the previous literature emphasizes the impact of offshoring on the skill premium, I find that job characteristics such as offshorability is critical in explaining the wage effect. Chapter 2 analyzes the effects of increasing import …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Three samples of Marcellus and Eau Claire shales were sheared in a modified Hassler style core holder. Before testing and after each shear step, the hydraulic transmissivity was measured and a high-resolution 3-D image taken using a computer tomography (CT) scanner, resolution ranged from 26.7 to 27.6 microns. Each sample was sheared four to eight times during a test providing a total of 37 fracture geometries. The 3-D binary images of each fracture were processed based on a voxel connectivity graph, removing any clusters that were not connected to the main fracture. Two-dimensional aperture maps were then generated by flattening …
Radial Growth Patterns In Trees Surviving Canopy Gap Disturbances, Ruth A. Stetler
Radial Growth Patterns In Trees Surviving Canopy Gap Disturbances, Ruth A. Stetler
Graduate Theses, Dissertations, and Problem Reports (ETD)
Forest disturbance regimes in eastern North America have long been conceptualized as localized gap disturbances, but recent studies suggest that more widespread, infrequent disturbance events may also be important. However, uncertainties in tree-ring methods used to detect disturbance, and in the factors that drive growth release of trees, limit the conclusions that can be drawn from regional disturbance analyses. I designed a study to further elucidate forest disturbance dynamics in eastern North America by using two approaches: 1) a case study examining the sensitivity of the radial growth averaging method of detecting disturbance and the factors influencing detection of a …
Biopolitical Cyborgs In Post-1980 North American Critical Dystopias, Valerie Ann Surrett
Biopolitical Cyborgs In Post-1980 North American Critical Dystopias, Valerie Ann Surrett
Graduate Theses, Dissertations, and Problem Reports (ETD)
Stories of babies born from transplanted uteruses, fetuses created from three biological parents, a booming global surrogacy market, and embryonic gene selection have all made national headlines in the past two years. We live in an era of science fictional childbirths. Reproductive technologies that didn't exist a decade ago are now peddled to whomever can afford them, and science fiction has responded. Post-1980 speculative fiction confronts a potent convergence of various sociopolitical and reproductive trends, including the rise of neoliberal conservatism; the "test tube baby" boom; polarized reproductive rights debates; and Diamond v. Chakrabarty (1980), the Supreme Court decision granting …
A Model For Permeability Reduction In Polymer Nanocomposites And Its Experimental Validation, Man Chio Tang
A Model For Permeability Reduction In Polymer Nanocomposites And Its Experimental Validation, Man Chio Tang
Graduate Theses, Dissertations, and Problem Reports (ETD)
Environmental concerns have led to research interest in biodegradable plastics, especially polylactic acid (PLA). PLA, a bio-derived and biodegradable polymer which is readily available, is easy to process, and it can be a good substitute for conventional non-biodegradable polymers in food packaging applications. However, its poor gas barrier property has to be improved to make it competitive with more widely-used materials such as polyethylene terephthalate (PET) and polystyrene (PS). This can potentially be accomplished by dispersing nanoplatelets in the polymer as these additives act as impermeable barriers around which the diffusing molecules are forced to take a longer, tortuous path. …

Salmonid Response To Habitat Restoration In A High-Elevation West Virginia Watershed, Cory T. Trego
Graduate Theses, Dissertations, and Problem Reports (ETD)
Brook trout Salvelinus fontinalis have experienced significant population declines throughout much of their native range, largely due to habitat loss. Increasing effort has been put toward restoring and preserving existing brook trout habitat in the face of continued loss under uncertain future conditions (e.g., climate change). We conducted a study designed to analyze both macroscale (i.e. at channel unit level) and microscale (i.e. within individual pools) habitat use in the context of stream restoration by brook trout and two competing nonnative salmonid species: brown trout Salmo trutta and rainbow trout Oncorhynchus mykiss. First we conducted a before-after-control-impact assessment of a …

Application Of Kalman Filtering For Pv Power Prediction In Short-Term Economic Dispatch, Luan H. Tran
Graduate Theses, Dissertations, and Problem Reports (ETD)
The aim of this thesis is to predict the short-term power production of PhotoVoltaic (PV) power plants for the economic dispatch problem with the help of Kalman filtering. The Economic Dispatch (ED) problem in power systems is known as an optimization problem in which the cost of producing energy to reliably supply consumers is minimized, hence the power production is assigned to all the generating units that are dispatchable. Because of the generation cost of renewable energy such as PV is relatively low, it is advantageous to utilize. However, these resources are intermittent. These renewable resources bring a lot of …
Implications Of Primary Cilia And Associated Lysophosphatidic Acid Signaling In Glioblastoma Biology And Therapy, Yuriy V. Loskutov
Implications Of Primary Cilia And Associated Lysophosphatidic Acid Signaling In Glioblastoma Biology And Therapy, Yuriy V. Loskutov
Graduate Theses, Dissertations, and Problem Reports (ETD)
The primary cilium is a ubiquitous organelle presented on most human cells. It serves as a crucial signaling hub for multiple pathways including growth factor and G-protein coupled receptors. Loss of primary cilia was observed in various cancers, however, the implications of this event are unclear. Several studies show that loss of cilia promotes cell proliferation, suggesting that alteration of ciliary-dependent signaling can drive the hyperproliferative phenotype of cancer cells, therefore re-establishing primary cilia or targeting altered signaling pathways could be a beneficial strategy as an anti-cancer therapy.;Glioblastoma (GBM) is one of the deadliest cancers with a median survival of …

Study Of Parameter Estimation And Model Calibration Using Bayesian Analysis Of Noisy Data For A Virus Model, Alejandro Mejia
Study Of Parameter Estimation And Model Calibration Using Bayesian Analysis Of Noisy Data For A Virus Model, Alejandro Mejia
Graduate Theses, Dissertations, and Problem Reports (ETD)
Numerous engineering problems are concerned with the challenge of representing real life systems through mathematical equations: modeling. Properly generated mathematical models can accurately predict the behavior of natural processes. The key objective of model development is to correctly build a set of equations or expressions that can reproduce the results observed from experimental measurements. By following this methodology, sources of error and uncertainty will arise as most natural processes have random factors that make the results stochastic, and therefore can never be exactly reproduced. A model can try to best approximate the actual outcome, but many times assumptions or simplifications …

Non-Equilibrium Green's Function Based Calculations Of Spin Voltage In Cobalt Based Spinel Oxides, Anveeksh Koneru
Graduate Theses, Dissertations, and Problem Reports (ETD)
Tougher sanctions on fossil fuel emissions and greater energy demand around the globe is forcing us to rely more on renewable energy resources. Clean energy technologies like thermoelectric power generation provides one solution to ease our dependence on non-renewable energy resources. Thermoelectric materials have the capability of directly converting heat to electricity. However, the efficiency of thermoelectrics has been limited due to the inherent coupling of the electronic and thermal carriers. More recently, an avenue to decouple these interactions has been experimental demonstrated using temperature gradient induced spin currents. With this new discovery comes the need for new transport models …
