Concerning The Interaction Of Forms, Luke Splinter

All Graduate Theses, Dissertations, and Other Capstone Projects

"Concerning the Interaction of Forms" is exactly what is in my mind when creating and thinking about work. I am concerned with all of the interactions that can be made when thinking about and looking at forms. How do the forms interact with one another? How do they interact with the space they are placed in? How do they interact with the viewer? These are the questions that concern me the most when creating work

When making work I do so with the help of basic geometric shapes, mathematic ratios, and the feeling I get from the form as it …

Global Data Association For Multiple Pedestrian Tracking, Afshin Dehghan

Electronic Theses and Dissertations

Multi-object tracking is one of the fundamental problems in computer vision. Almost all multi-object tracking systems consist of two main components; detection and data association. In the detection step, object hypotheses are generated in each frame of a sequence. Later, detections that belong to the same target are linked together to form final trajectories. The latter step is called data association. There are several challenges that render this problem difficult, such as occlusion, background clutter and pose changes. This dissertation aims to address these challenges by tackling the data association component of tracking and contributes three novel methods for solving …

Customized Medicine And The Limits Of Federal Regulatory Power, Anna B. Laakmann

Vanderbilt Journal of Entertainment & Technology Law

The Food and Drug Administration (FDA) plays a dominant role in setting national policy and standards for the biomedical industry. Yet there are significant statutory constraints on the agency's power. The FDA's main implementing statute, the Federal Food, Drug, and Cosmetic Act (FDCA), bounds the scope of the FDA's regulatory authority. The FDCA cabins FDA power in two important ways: (1) with a few notable exceptions, the FDA lacks power to regulate local activities that are not directly connected to interstate commerce, and (2) the agency may regulate product manufacturers, but not service providers. The FDA has long grappled with …

Mathematical Modeling Of Heart Rate Deflection Point In Relation To Respiratory Compensation And Treadmill Running Performance, Kayla Baker

Electronic Theses and Dissertations

Heart rate deflection point (HRDP), identified as the second breakpoint in the "intensity / heart rate" relationship, is indicative of the anaerobic threshold (AT). This point can be determined via bi-segmental linear regression (2SEG) or through use of the maximal distance model (D-max); however, the relationship between these methods has yet to be investigated 2. Purpose: To compare the use of 2SEG and D-max methods to determine HRDP and to examine the relationship between these values with a metabolic threshold, respiratory compensation point (RCP), as well as running performance [5,000 meter treadmill time trial (5Ktime)]. Methods: Nineteen recreationally active men …

A Review Of Natural And Engineered Enzymes Involved In Bioethanol Production, Ines Cuesta Urena

Graduate Student Theses, Dissertations, & Professional Papers

Alternative petroleum-derived fuels, such as biofuels, is another form to decrease the dependence of non-renewable energy. The most promising alternative energy is cellulosic ethanol because of the abundance of cellulose and the overall lack of concern for the food-versus-fuel dilemma.

In order to produce ethanol from cellulosic materials, pretreatment is required to “open” the lignocellulosic matrix and make cellulose more susceptible to enzymatic degradation. Enzymatic hydrolysis of lignocellulose is an important area of research due to the absence of negative effects in downstream processes in comparison with acid hydrolysis. Both natural enzymes and engineered enzymes can be used in the …

Spatial Scaling Of Crustal And Lithospheric Deformation In The Western United States, Cody W. Bomberger

Graduate Student Theses, Dissertations, & Professional Papers

Deformation of continental lithosphere can extend great distances laterally from tectonic plate boundaries. This extent has been used to argue for a variety of constitutive laws for continental materials, based on the underlying principles in continuum mechanics that identify a relationship between characteristic spatial scale and material properties. Although the relationship between observed deformation and material models is always non-unique, quantifying one or more characteristic scales of deformation in a region can rule out some models of how the lithosphere deforms. In the western United States active deformation occurs at the plate boundary between North America and either the Pacific …

The Effects Of Aging On Multiple Postural Muscle Control And Postural Sway Behavior, Adriana Menezes Degani

Graduate Student Theses, Dissertations, & Professional Papers

Episodes of instability and falls in the elderly represent a major public health concern. The lack of scientific information about the effects of age-related changes on neurophysiological mechanisms of postural control has limited the advance in the field of fall prevention and rehabilitation of balance disorders. The overall goal of this dissertation was to investigate the effects of aging on postural control. Considering the progressive non-homogeneous deterioration of aging physiological systems, a series of five experimental studies, with healthy young and healthy nonfaller older adults performing upright stance tasks, explored three main hypotheses: (1) intermuscular coherence analysis is able to …

UMLS::Association - A Semantic Association Framework for Biomedical Texts

Keith Herbert

Natural Language Processing Lab, Department of Computer Science

Introduction

We present UMLS::Association, a software package to explore the semantic association of biomedical terms with applications for literature-based discovery. Literature-based discovery is an endeavour to ”connect the dots” for scientists between the topics of their research and those of unexpected relevance. However, many approaches rely on the exact wording for the ideas in the research papers being analyzed. The Unified Medical Language System (UMLS) provides a way to map natural language phrases in these papers to sequences of abstract yet …

Increasing College Opportunity: School Counselors And Fafsa Completion, Laura Owen, Erik Westlund

Journal of College Access

Closing postsecondary opportunity gaps has become a national, state and local educational priority. To help eliminate these gaps, the US Department of Education initiated a project that provided real time student level Free Application for Federal Student Aid (FAFSA) completion status to large urban school districts. Leveraging this information, school counselors identified and supported students and families as they navigated the financial aid process, resulting in statistically significant impacts on FAFSA completion and college attendance.

Keeping The Promise: Factors Affecting Timing To Merit Scholarship Loss, Jacob P.K. Gross, Angela D. Bell, Matthew Berry

Journal of College Access

Despite increased attention paid to the advent and development of state merit scholarship policies (such as Georgia’s Helping Outstanding Pupils Educationally) and some evidence that suggests differences in scholarship retention by socioeconomic status or other student characteristics, little empirical work has explored factors affecting scholarship retention. Moreover, no work has explored what affects the timing of scholarship loss. This study employs event history modeling to ascertain not only what factors impact students’ retention of the West Virginia PROMISE Scholarship but also when these factors are most influential.

Modeling Of Selection Of Supply Sources For Hospitals, Siva Raghava Sai Rohith Valiveti

Graduate Dissertations and Theses

Most of the hospitals in the USA carry out their purchasing of supplies, including pharmaceuticals, through Group Purchasing Organizations (GPO). GPO is an organization, which aggregates procuring volumes of their member hospitals and negotiates low prices from manufacturers or vendors. According to 2013 statistics, 98% of hospitals in U.S. are purchasing their bulk health care products through GPOs, and it saves U.S. health care industry approximately $36 billion annually. Through these hospitals enjoy advantages by purchasing through their GPOs, there are some disadvantages such as paying membership fees to their GPOs, restricting the purchasing power of the hospitals outside their …

Rhenium-Pyridyl-Nhcs For Photocatalytic Co2 Reduction, Emily Anne Sharpe

Honors Theses

The ability to transform CO2 into a useable fuel source would have a remarkably positive impact on the environment by taking the vast amounts of previous unusable CO2 from the atmosphere and reducing it to CO, which can then be turned into fuel. This project involves the synthesis and testing of air and water stable Re (I) pyridyl N- heterocyclic carbene (NHC) compounds for photocatalytic reduction of CO2 into CO using a simulated solar spectrum. Previous research in this area focused on the use of Re(bpy)CO3X, which quickly became the benchmark of homogeneous CO2 reduction photocatalysts. The Re (I) pyridyl …

The Synthesis Of Substituted Pentadentate Ligand Scaffolds And Their Future Application In Ruthenium-Catalyzed Water Oxidation, Manpreet Singh

Honors Theses

Rising global energy demands coupled with depleting natural resources have led to a strong emphasis on finding new sources of energy that are renewable and which limit the negative impact on the environment. One of the strongest candidates is utilizing solar energy to drive water oxidation to produce hydrogen as a fuel source. In order to do this, a better understanding of the mechanism involved in this process must be revealed. Homogenous molecular catalysts allow mechanistic studies and can be also used in Photoelectrochemical Cells (PECs) and other systems to produce chemical fuels. In this work, the new syntheses of …

The Evolution Of The Sugarcoated American Food Market And The Paradox Of Artificial Sweeteners, Mary Moses Hitt

Honors Theses

Living in present-day America makes it hard to imagine an era when sugar was not as inexpensive and readily available as it is now. It is in little colorful packets on restaurant tables, filled to the brim in jars at coffee shops, or mixed into candy products located at the beginning of every cash register. Today, sugar is one of, if not, the most widely consumed food products in the world, but our love for sugar is nothing new. Humans have been experiencing the bliss triggered by sweet-tasting foods since their earliest diets, which included fruits and honey. Our diets …

Is Accounting For Stock Options Manipulated Before And After An Initial Public Offering?, Natalie Marie Flood

Honors Theses

Stock option accounting is an area in financial statements that requires substantial estimates and management discretion. Previous research in the area of stock option accounting has found that valuations of options and subsequent accounting methods have been incorrectly stated to aid a company to look financially stronger. Companies that are about to undergo an initial public offering have the most incentive to incorrectly state the value of their options. However, all of these studies have used financial data from financial statements dated before 2004. This is significant because FASB Standard 123(R) (2004) and the Sarbanes-Oxley Act (2000) have both been …

Nonlinear Optical Observation Of Coherent Acoustic Dirac Plasmons In Thin-Film Topological Insulators, Yuri D. Glinka, Sercan Babakiray, Trent A. Johnson, Mikel B. Holcomb, David Lederman

Faculty & Staff Scholarship

Low-energy collective electronic excitations exhibiting sound-like linear dispersion have been intensively studied both experimentally and theoretically for a long time. However, coherent acoustic plasmon modes appearing in time-domain measurements are rarely observed due to Landau damping by the single-particle continua. Here we report on the observation of coherent acoustic Dirac plasmon (CADP) modes excited in indirectly (electrostatically) opposite-surface coupled films of the topological insulator Bi2Se3. Using transient secondharmonic generation, a technique capable of independently monitoring the in-plane and out-of-plane electron dynamics in the films, the GHz-range oscillations were observed without corresponding oscillations in the transient reflectivity. These oscillations were assigned …

An Analysis Of Accuracy Using Logistic Regression And Time Series, Edwin Baidoo, Jennifer L. Priestley

Published and Grey Literature from PhD Candidates

This paper analyzes the accuracy rates for logistic regression and time series models. It also examines a relatively new performance index that takes into consideration the business assumptions of credit markets. Although prior research has focused on evaluation metrics, such as AUC and Gini index, this new measure has a more intuitive interpretation for various managers and decision makers and can be applied to both Logistic and Time Series models.

Published and Grey Literature from PhD Candidates

The aim of this paper to predict a past-due amount using traditional and machine learning techniques: Logistic Analysis, k-Nearest Neighbor and Random Forest. The dataset to be analyzed is provided by Equifax, which contains 305 categories of financial information from more than 11,787,287 unique businesses from 2006 to 2014. The big challenge is how to handle with the big and noisy real world datasets. Among the three techniques, the results show that Logistic Regression Method is the best in terms of predictive accuracy and type I errors.

Application Of Isotonic Regression In Predicting Business Risk Scores, Linh T. Le, Jennifer L. Priestley

Published and Grey Literature from PhD Candidates

An isotonic regression model fits an isotonic function of the explanatory variables to estimate the expectation of the response variable. In other words, as the function increases, the estimated expectation of the response must be non-decreasing. With this characteristic, isotonic regression could be a suitable option to analyze and predict business risk scores. A current challenge of isotonic regression is the decrease of performance when the model is fitted in a large data set e.g. more than four or five dimensions. This paper attempts to apply isotonic regression models into prediction of business risk scores using a large data set …
