Transforming Undergraduate Stem Education: Reforming Classrooms By Training Current And Future Faculty, Karen E. Bailey

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the absence of formal pedagogical training, educators tend to teach the way they were taught, using traditional lecturing. Numerous studies have shown that engaging students in active learning improves student learning and retention of knowledge. Reforming STEM education has become a national imperative. Since the turn of the millennium, many initiatives have sprung forth in response to a growing awareness of the need for reform in post-secondary biology education. The National Academies Summer Institutes (NASI) is one such initiative. The Summer Institutes provide training in evidence-based strategies for biology educators from primarily research universities where lecture-based teaching in large …

Choice Dynamics In Concurrent Ratio Schedules Of Reinforcement, Daniel Bell-Garrison Jan 2018

Choice Dynamics In Concurrent Ratio Schedules Of Reinforcement, Daniel Bell-Garrison

Graduate Theses, Dissertations, and Problem Reports (ETD)

Roughly 50 years of research has demonstrated that choice changes as a function of the amount of reinforcement available from two concurrently available schedules of reinforcement, and this function has been labeled the generalized matching law. The matching law, however, historically only accounts for choice between two variable-interval schedules of reinforcement. If the matching law is to be a general perspective for how organisms allocate behavior amongst several alternatives, then it ought to account for behavior when reinforcers depend on work requirements in addition to time requirements. To study these contexts, the present experiments employed concurrent ratio schedules that were …

A Long Short-Term Memory Neural Network For Improved Twins' Voice Differentiation, Stallone Bruno-Ray Sabatier Jan 2018

A Long Short-Term Memory Neural Network For Improved Twins' Voice Differentiation, Stallone Bruno-Ray Sabatier

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although successfully implemented in certain situations, the reliability of speaker recognition (SR) decreases due to speaker and channel variability present between enrollment and evaluation samples, as well as the available length of speech utterances. The issue of speaker variability becomes more pronounced when the number of speakers in the evaluation set increases, as there is a higher probability that two voices may sound more alike. The differentiation of intra-twin pairs' voices can be beneficial to general SR because inclusion can simulate this effect. This is due to the fact that their shared voice similarities are comparable to the potential inter-speaker …

Rethinking Interaction: Identity And Agency In The Performance Of “Interactive” Electronic Music, Jacob A. Kopcienski Jan 2018

Rethinking Interaction: Identity And Agency In The Performance Of “Interactive” Electronic Music, Jacob A. Kopcienski

Graduate Theses, Dissertations, and Problem Reports (ETD)

This document investigates interaction between human performers and various interactive technologies in the performance of interactive electronic and computer music. Specifically, it observes how the identity and agency of the interactive technology is experienced and perceived by the human performer. First, a close examination of George Lewis’ creation of and performance with his own historic interactive electronic and computer works reveals his disposition of interaction as improvisation. This disposition is contextualized within then contemporary social and political issues related to African American experimental musicians as well as an emerging culture of electronic and computer musicians concerned with interactivity. Second, an …

Hydrogeology And Water Management In The Arkwright Underground Coal Mine, Pittsburgh Seam, Northern West Virginia, Bryant D. Mountjoy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Arkwright #1 is a closed underground mine in the Pittsburgh coal seam near Morgantown, West Virginia USA. Arkwright shares perimeter boundaries/barriers with three other closed Pittsburgh seam mines (Osage #3, Jordan #93, Federal #1) and is partially overlain by flooded Sewickley seam mines, 25 m above it. This mine is significant primarily because it manages and treats water diverted from nearly 20 other closed mines over a 600 square kilometer area. This study examines water levels, pump records, and mine maps to describe the hydrogeology of Arkwright Mine. After closure in 1995, Arkwright and the adjacent northern Osage mines began …

Reducing Spatial Stochastic Models Of Membrane Receptors To Approximately Equivalent Chemical Reaction Networks Through Coarse Graining, Christopher Short Jan 2018

Reducing Spatial Stochastic Models Of Membrane Receptors To Approximately Equivalent Chemical Reaction Networks Through Coarse Graining, Christopher Short

Graduate Theses, Dissertations, and Problem Reports (ETD)

Computational models are necessary for understanding how biological functionality emerges from a complex network of molecular interactions such as in cell signaling. Due to the complexity of biological systems, the normal scientific method of hypothesizing then testing predictions is becoming increasingly difficult. The large number of processes limits the level of modeling detail; signaling models typically adopt a non-spatial representation where each molecular process is characterized by a few parameters.;However, modern microscopic imaging of receptors on cell membranes reveals an intricate structure of microdomains. Receptors, such as epidermal growth factor receptor (EGFR), vascular endothelial growth factor receptor (VEGFR), and others, …

Existence Of Global Solutions For Nonlinear Magnetohydrodynamics With Finite Larmor Radius Corrections, Fariha Elsrrawi Jan 2018

Existence Of Global Solutions For Nonlinear Magnetohydrodynamics With Finite Larmor Radius Corrections, Fariha Elsrrawi

Graduate Theses, Dissertations, and Problem Reports (ETD)

We discuss the existence of global solutions to the MHD equations where the effects of finite Larmor radius corrections are taken into account. Unlike the usual MHD, the pressure is a tensor and it depends on not only the density but also the magnetic field. We show the existence of global solutions by the energy methods. Our techniques of proof are based on the existence of local solution by Semigroups theory and a priori estimates.

Graph Coloring Problems And Group Connectivity, Miaomiao Han Jan 2018

Graph Coloring Problems And Group Connectivity, Miaomiao Han

Graduate Theses, Dissertations, and Problem Reports (ETD)

1. Group connectivity. Let A be an abelian group and let iA(G) be the smallest positive integer m such that Lm(G) is A-connected. A path P of G is a normal divalent path if all internal vertices of P are of degree 2 in G and if |E(P)|= 2, then P is not in a 3-cycle of G. Let l(G) = max{lcub}m : G has a normal divalent path of length m{rcub}. We obtain the following result. (i) If |A| ≥ 4, then iA( G) ≤ l(G). (ii) If | A| ≥ 4, then iA(G) ≤ |V(G)| -- Delta(G). (iii) …

Detecting The Onset Of The Bulk Crystal Plasticity Transition In Face Centered Cubic Metals Using Nanoindentation, Ryder Bolin Jan 2018

Detecting The Onset Of The Bulk Crystal Plasticity Transition In Face Centered Cubic Metals Using Nanoindentation, Ryder Bolin

Graduate Theses, Dissertations, and Problem Reports (ETD)

The present thesis showcases the investigation of nanoindentation at ultra-low depths (<500nm), for the study of the origin and initiation of crystal plasticity in a number of Face Centered Cubic (FCC) metals: Nickel (Ni), Copper (Cu), and Aluminum (Al) in single crystalline or polycrystalline form. Nanoindentation was carried out using a Berkovich tip, and indentations were carried out in the nano-regime of polycrystalline FCC metals and single crystalline Cu and Al. Two custom-built four-point bending apparatuses were used to apply in-plane tension on all samples during indentation. Samples were indented using both displacement and load controls, in order to both carefully estimate the hardness and plasticity noise as a function of depth and applied in-plane tension. The noisy character of crystal plasticity manifests itself through nanoindentation pop-in events, which are abrupt and stochastic plastic displacements during the initial stage of plasticity. I discuss and demonstrate indentation size effects induced and/or promoted by the in-plane stress in FCC materials. The hardness analysis shows a statistically inverse dependence on in-plane stress for small depth indentation and I discuss the consistency of the effects in both the hardness and pop-in events among the various FCC crystals studied. Finally, I discuss a novel approach to detect the onset of pop-in noise in a realistic sample without special treatment and demonstrate its consistency for Cu single crystalline samples.

Investigation Of Combustion Characteristics Of A Heavy-Duty Diesel Engine Retrofitted To Natural Gas Spark Ignition Operation, Jinlong Liu Jan 2018

Investigation Of Combustion Characteristics Of A Heavy-Duty Diesel Engine Retrofitted To Natural Gas Spark Ignition Operation, Jinlong Liu

Graduate Theses, Dissertations, and Problem Reports (ETD)

The conversion of existing diesel engines to natural-gas spark ignition operation by adding a gas injector in the intake manifold for fuel delivery and replacing the diesel fuel injector with a spark plug to initiate and control the combustion process can reduce U.S. dependence on petroleum imports and curtail engine-out emissions. As the conventional diesel combustion chamber (i.e., flat head and bowl-in-piston) creates high turbulence, the engine can operate leaner, which would increase its efficiency and reduce emissions. However, natural gas combustion in such retrofitted engines presents differences compared to that in conventional spark ignited engines. Subsequently, the main goal …

Algorithmic Issues In Some Disjoint Clustering Problems In Combinatorial Circuits, Zola Nailah Donovan Jan 2018

Algorithmic Issues In Some Disjoint Clustering Problems In Combinatorial Circuits, Zola Nailah Donovan

Graduate Theses, Dissertations, and Problem Reports (ETD)

As the modern integrated circuit continues to grow in complexity, the design of very large-scale integrated (VLSI) circuits involves massive teams employing state-of-the-art computer-aided design (CAD) tools. An old, yet significant CAD problem for VLSI circuits is physical design automation. In this problem, one needs to compute the best physical layout of millions to billions of circuit components on a tiny silicon surface. The process of mapping an electronic design to a chip involves several physical design stages, one of which is clustering. Even for combinatorial circuits, there exist several models for the clustering problem. In particular, we consider the …

Group Connectivity And Modulo Orientations Of Graphs, Jiaao Li Jan 2018

Group Connectivity And Modulo Orientations Of Graphs, Jiaao Li

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation focuses on the subject of nowhere-zero flow problems on graphs. Tutte's 5-Flow Conjecture (1954) states that every bridgeless graph admits a nowhere-zero 5-flow, and Tutte's 3-Flow Conjecture (1972) states that every 4-edge-connected graph admits a nowhere-zero 3-flow. Jaeger et al. (1992) further conjectured that every 5-edge-connected graph is Z3-connected, whose truth implies the 3-Flow Conjecture. Extending Tutte's flows conjectures, Jaeger's Circular Flow Conjecture (1981) says every 4p-edge-connected graph admits a modulo (2 p + 1)-orientation, that is, an orientation such that the indegree is congruent to outdegree modulo p + 1 at every vertex. Note that the p …
