An Interpolation Based Approach For Pattern Recognition And Generation, Vishnukumar Galigekere Nagabhushana
An Interpolation Based Approach For Pattern Recognition And Generation, Vishnukumar Galigekere Nagabhushana
Computer Science and Engineering Dissertations - Archive
A large number of problems in computer vision and computer graphics can essentially be reduced to a pattern recognition problem. In this thesis, we explore a novel interpolation based framework to address some of the various recognition problems in these areas. Our interpolation based framework is a supervised learning algorithm that allows for both generation (synthesis) of new patterns as well as perception (analysis) of existing patterns. The method is simple to implement and yet, expects a very straightforward and intuitive set of parameters to model the complex nature of such recognition problems.Specifically, given a set of training data along …

Optimized Estimates Based On Multiple Sensor Configuration Knowledge, Roochi Mishra
Industrial, Manufacturing, and Systems Engineering Dissertations - Archive
There has been an increase in the usage of sensor technology as they are adaptable for use in different environments, many of which are hostile to direct human observation, such as regions affected by land mines or forest fires. The sensors used to monitor developing situations are small inexpensive computing devices with limited processing capabilities, limited power supply and may be destroyed in the event that they are monitoring, without suffering a great financial cost. Also, since these devices are inexpensive, multiple sensors can be deployed for the same application where the sensors are placed or attached to a mobile …

Mathematical Programming Approaches For Land Use Planning That Limits Urban Sprawl, Piyush Kumar
Industrial, Manufacturing, and Systems Engineering Dissertations - Archive
Sprawl has a detrimental effect on quality of life and the environment. For example, it increases our dependence on vehicles for daily tasks. This leads to increased vehicular pollution. It also increases traffic, which results in people spending more time on the road. With dwindling resources and increasing population, it becomes necessary that we manage sprawl. Ewing et al. defined factors to measure sprawl in the present urban structure. The measures are divided into four broad categories, which are density factors, mixed use factors, streets factor, and centers factors. These measures address various aspects that contribute to sprawl. For example, …

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive
Multivariate Adaptive Regression Splines (MARS) is a statistical modeling method used to represent high-dimensional data with interactions. It uses different algorithms to select the terms to be included in the approximation model that best represent the data. In addition, it performs a variable selection, therefore the most significant predictors are shown in the final model. Design and analysis of computer experiments (DACE) is a statistical technique for creating approximations (called metamodels) of computer models. For optimization problems in which there is an unknown function that must be approximated, DACE approach could be applied. In stochastic dynamic programming (SDP) for example, …

Development And Validation Of The Resilience Protective Factors Inventory: A Confirmatory Factor Analysis, Kristin Whitehill Bolton
Development And Validation Of The Resilience Protective Factors Inventory: A Confirmatory Factor Analysis, Kristin Whitehill Bolton
Social Work Dissertations - Archive
The concept of resilience was empirically discovered over 40 years ago. Over the last several decades' researchers continued to generate a theoretical and empirical evidence base relative to the concept of resilience. This study builds on the existing theoretical and empirical literature of resilience in an attempt to construct a measurement model capable of assessing the protective factors associated with resilience in an older adult population. The development of the tested measurement model was two-fold (N=151). First, a qualitative interpretive meta-synthesis (QIMS) of qualitative studies on resilience among older adults was performed. Findings from the QIMS revealed 9 factors: Grit, …
Professional Preparation And Practices Of Child Custody Evaluators: A Comparative Study Of Masters-Level And Doctoral-Level Practitioners, Aaron Robb
Social Work Dissertations - Archive
While a substantial amount of the research on child custody evaluation practices has focused on psychologists and psychiatrists, virtually none of the existing research has addressed child custody evaluation practices of social workers or other mental health professionals. This study explores and describes the training and practice differences between doctoral-level child custody evaluators, primarily psychologists, and their masters-level counterparts, who are drawn from a much wider professional background. The exact population of evaluators in the community is unknown, thus a snowball sampling method was utilized for outreach to evaluators who then provided responses to a survey instrument. Statistical comparisons of …

Bystander Sexual Violence Prevention Program: Implementation And Evaluation With High-Risk University Males, Nada Elias-Lambert
Social Work Dissertations - Archive
This research reports the findings of an evaluation of a theoretically-based, peer-facilitated, bystander sexual violence prevention program to determine its effectiveness at changing attitudes and behaviors related to sexual violence with university males who are at low- and high-risk of using sexually coercive behavior. Bystander interventions focus on men and women as bystanders to change social norms in a peer culture that supports abusive behaviors. Few studies have examined the effectiveness of these interventions with high-risk populations, which is the focus of this study. A bystander sexual violence prevention program was presented to 142 fraternity members in 2012. A quasi-experimental …

Deterrent Effects Of Reliable Structured Decision-Making Protocols On Spouse Abuse Perpetration And Re-Offense In The U.S. Army, Tyler Dumars
Social Work Dissertations - Archive
Since the early 1980s, victims' rights advocates, law enforcement officials, health care practitioners, and policymakers have all worked diligently to reduce or arrest the high levels of intimate partner violence (IPV) in military communities. Despite increased awareness and funding, new treatment approaches, and numerous policy changes, IPV in the military continues to be a deeply entrenched and recalcitrant problem. In January 2008, the Army began using a structured decision-making protocol (the Decision Tree Algorithm) that requires users to assess whether alleged incidents of intimate partner abuse coincide with evidence-based maltreatment definitions, and indicate that actual harm (or the potential for …
Development Of An Adaptation Model For Health Interventions For Sexual And Gender Minorities: A Grounded Theory Study, Pamela Hancock Bowers
Development Of An Adaptation Model For Health Interventions For Sexual And Gender Minorities: A Grounded Theory Study, Pamela Hancock Bowers
Social Work Dissertations - Archive
A dearth of literature exists on health issues impacting sexual and gender minority (SGM) populations. SGM face health disparities linked to stigma, discrimination, and denial of their civil and human rights. Albeit limited in scope and depth, available data suggests sexual orientation and gender identity have been an important demographic factor associated with higher risk for several negative health outcomes such as cancer, cardiovascular disease, and stroke. Some of the major inequities affecting SGM include tobacco use, alcohol and illicit drug abuse, being overweight/obese, psychiatric disorders, and violence. The SGM who face health disparities created by the use of various …

Curriculum and Instruction Faculty Publications - Archive
Donor funding has helped enroll in school most children of low-income countries. However, students get little schooling and few opportunities to encode and consolidate information. Many fail to learn and automatize the small units needed for more complex skills, such as reading. As a result, many children remain illiterate and drop out in the early primary grades. However, donors and governments often focus on the socioeconomic difficulties of the very poor and have limited insights on how to teach students who get no academic preparation before grade 1. Furthermore, staff experiences with middle class schools may promote complex instructional methods …
Effects Of Cooling And Heating Fans On Thermoregulation, David Cooley
Effects Of Cooling And Heating Fans On Thermoregulation, David Cooley
Kinesiology Student Research - Archive
INTRODUCTION: The human body must maintain a constant internal environment for optimal operation of cellular activity. This homeostatic balance is maintained at rest but becomes more of a challenge during exercise. An important internal regulatory mechanism is thermoregulation. Thermoregulation is defined as the ability of an organism to maintain a core body temperature within certain boundaries, even when internal and external temperatures are altered. The hypothalamus is responsible for keeping the body’s core temperature within a normal range, around 97 to 99 degrees Fahrenheit, at rest and during exercise. PURPOSE: The purpose of this study was to determine the effects …

Solving The Optimization Control Problem For Lunar Soft Landing Using Minimization Technique, Lizeth Patricia Ocampo
Mathematics Theses - Archive
Minimizing fuel consumption in lunar missions has been a well studied and documented optimization problem. In this paper two cases of the lunar Lander are studied. The first case is the one dimensional problem where the objective is to make a vertical soft landing using the minimum amount of fuel. The second case has the same objective but an initial tangential velocity greater than zero is given making it a two dimensional problem. The first case is solved using Newton's shooting method, finite difference method (using MATLAB's embedded function bvp4c), and solving it explicitly. For the second case, a minimization …
The Role Of Religion In Managing Existential Threat: Effects On Outgroup Attitudes, Lauren Elizabeth Coursey
The Role Of Religion In Managing Existential Threat: Effects On Outgroup Attitudes, Lauren Elizabeth Coursey
Psychology Theses - Archive
The increased worldview defense following mortality salience is a robust finding in terror management theory research. In some cases, this defense can take the form of ingroup favoritism, outgroup bias, and prejudice. I predicted that religious affiliation would attenuate the effects of mortality salience on expressions of prejudice. Specifically, I predicted an interaction between religious affiliation and mortality salience to emerge, such that whereas the religiously non-affiliated will exhibit an increase in prejudice scores following mortality salience, the religiously affiliated will not. I further hypothesized that among religiously affiliated participants, the interaction between MS and affiliation will predict outgroup attitudes …

What Are The Long-Term Consequences Of Peer Victimization? Changes In Biological Functioning And Its Effects On Psychological And Physical Health, Priya Anapurna Iyer
Psychology Dissertations - Archive
Prior research has documented long-term psychological problems (e.g. emotional distress, anxiety, and depression; Kochenderfer-Ladd & Wardrop, 2001) experienced as a result of being bullied as an adolescent. Although being a recipient of peer victimization has been related to psychological health, limited research has looked at the association between peer victimization and physical health problems. Even fewer studies have investigated the relationship between being bullied and health outcomes over time. This dissertation examined whether peer victimization in early adolescence lead to changes in neuroendocrine functioning (as assessed by cortisol) and physical health outcomes several years later. Adolescents and their parents (N …
An Examination Of The Validity Of The Central Sensitization Inventory With Chronic Disabling Occupational Musculoskeletal Disorders, Yunhee Choi
Psychology Dissertations - Archive
Central Sensitivity Syndrome (CSS) includes a group of related conditions that share a common pathophysiological mechanism called central sensitization (e.g., fibromyalgia, irritable bowel syndrome, tension headache/migraine, etc.). Individuals with these conditions display increased pain sensitivity in response to painful stimuli, pain in response to normally non-painful stimuli, and expansion of the receptive field. Depression and anxiety frequently occur among individuals with CSS, as well as disturbed sleep, somatic symptoms and emotional distress. The Central Sensitization Inventory (CSI) is a newly developed self-report measure to assess the full array of 25 somatic and emotional symptoms associated with CSS. The present study …

Optimization Of Energy Resolution In The Digital Hadron Calorimeter Using Longitudinal Weights, Jacob Russell Smith
Physics Dissertations - Archive
Particle physics seeks to describe matter in its most elementary structure. With lepton colliders; couplings of gauge bosons and heavy quarks, physics beyond the Standard Model, and properties of a recently discovered Higgs boson can be studied with very high precision. Particle Flow Algorithms (PFA), able to achieve necessary jet-energy and di-jet mass resolutions, require fine transverse and longitudinal segmentation from calorimeters. To validate digital imaging calorimetry in this context, a Digital Hadron Calorimeter (DHCAL) with single-bit (digital) readout on imbedded electronics from 1×1 cm2 pads throughout its volume has been constructed and exposed to particle beams as a large …
The Impact Of Peer Victimization On Adolescent Inflammatory Markers, Allyson Antoinette Arana
The Impact Of Peer Victimization On Adolescent Inflammatory Markers, Allyson Antoinette Arana
Psychology Theses - Archive
For years, research has linked peer victimization to various outcomes, ranging from those in the psychological realm (e.g., depression, anxiety) to physical health symptoms (e.g., frequent doctor visits, abdominal pain). While there are many possible mechanisms responsible for this relationship, this study focused on immune system dysregulation, specifically concerning the inflammatory markers interleukin-6 (IL-6) and C-reactive protein (CRP). Prior research has found that environmental stress is related to increased production of these markers (e.g., Danese et al., 2007; Kiecolt-Glaser et al., 2003). Furthermore, elevated levels of IL-6 and CRP have been associated with health problems such as cardiovascular disease, cancer, …
