Methodologies To Exploit Atpg Tools For De-Camouflaging, Deepak Reddy Vontela

USF Tampa Graduate Theses and Dissertations

Semiconductor supply chain is increasingly getting exposed to Reverse Engineering (RE) of Intellectual Property (IP). Camouflaging of gates in integrated circuits are typically employed to hide the gate functionality to prevent reverse engineering. The functionalities of these gates cannot be found by De-layering as they don’t leave any layout clues. Adversaries perform reverse engineering by replacing the camouflaged gate with the known gate and by developing custom software to determine test patterns. These test patterns are used to analyze the outputs and to conclude the functionality of the camouflaged gate.

In this thesis, we show that reverse engineering of camouflaged …

Pedestrian Detection In Low Quality Moving Camera Videos, Saurabh Hinduja

USF Tampa Graduate Theses and Dissertations

Pedestrian detection is one of the most researched areas in computer vision and is rapidly gaining importance with the emergence of autonomous vehicles and steering assistance technology. Much work has been done in this field, ranging from the collection of extensive datasets to benchmarking of new technologies, but all the research depends on high-quality hardware such as high-resolution cameras, Light Detection and Ranging (LIDAR) and radar.

For detection in low-quality moving camera videos, we use image deblurring techniques to reconstruct image frames and use existing pedestrian detection algorithms and compare our results with the leading research done in this area.

Gynecomastia: Psychological Correlates And A Test Of The Tripartite Influence Model Of Body Image, Daniel Luis Ordaz

USF Tampa Graduate Theses and Dissertations

Gynecomastia is the proliferation of breast tissue in men. The purpose of this study was to compare psychological functioning across three groups of participants: treatment seeking men with gynecomastia, non treatment seeking men with gynecomastia, and men without gynecomastia. Though very little research has been done with this population, some research suggests poor psychological outcomes of gynecomastia. MANCOVA was used to test differences in psychological functioning across the three groups, and multiple regression was used to predict quality of life from psychological variables. Significant differences emerged between groups, with men with gynecomastia reporting worse psychological functioning. Additionally, no theoretical model …

Design And Development Of Peptidomimetic Ligands For Targeting Radiopharmaceuticals, Imaging Probes, And Immunotherapeutics In Oncologic Disease, Michael Lawrence Doligalski

USF Tampa Graduate Theses and Dissertations

Cancer is a leading cause of morbidity and mortality in the developed world. While much has been learned about these diseases in the last few decades, one of the main barriers to widespread advancement is the heterogeneity of cancer biology. A growing body of evidence supports the idea that certain protein receptors are overexpressed on the surface of tumor cells as compared to normal tissues. These extracellular biomarkers provide a unique opportunity to selectively target the tumor with both imaging and therapeutic modalities. The research in this dissertation focuses on targeting proteins on the tumor cell surface with peptidomimetic ligands. …

Feeding Patterns And Trophic Food Web Dynamics Of Armases Cinereum Across A Mangrove/Upland Ecotone, Erin Paige Kiskaddon

USF Tampa Graduate Theses and Dissertations

The feeding ecology of a common saltmarsh crab, Armases cinereum (Armases), was investigated to determine how habitat (mangrove vs. ecotone, natural mangrove vs. modified mangrove fringe) influenced this species’ feeding behavior and trophic ecology in its southwestern Florida, USA, distribution. In the laboratory, Armases’ preference for mangrove material was examined using leaves of three mangrove species (Avicennia germinans, Laguncularia racemosa, and Rhizophora mangle) and leaves of different degradation levels (fresh, senescent, and partially-decomposed). Leaf material from A. germinans was preferentially consumed over the other taxa at fresh and partially-decomposed levels of leaf decay. When Armases were …

Abundance Of Archaias Angulatus On The West Florida Coast Indicates The Influence Of Carbonate Alkalinity Over Salinity, Sean Thomas Beckwith

USF Tampa Graduate Theses and Dissertations

Archaias angulatus, a large symbiont-bearing foraminifer (Order Miliolida) that produces a Mg-calcite shell, is common throughout the Caribbean and warm western Atlantic region. This species lives abundantly in seagrass beds along the Springs Coast of northwest Florida (up to 4 adults per gram of sediment) where spring-fed rivers emerge from a limestone aquifer, and in Florida Bay to the southeast (25 adults/g) where the sediment is primarily biogenic carbonate. In contrast, live specimens are seldom found in the seagrass beds along the central-west coast of Florida, where barrier islands are dominated by quartz sand. My working hypothesis is that substratum …

The Influence Of Context On L2 Development: The Case Of Turkish Undergraduates At Home And Abroad, Zeynep Koylu

USF Tampa Graduate Theses and Dissertations

In the field of second language acquisition (SLA), the study abroad context (SA) has gained attention as a site that offers the potential of significant second language (L2) development due to high amounts of input and interaction opportunities compared to at home foreign language (AH) and domestic immersion (IM) contexts (Pérez-Vidal, 2014). In previous research, the SA context has been a country where the L2 is the local language (e.g., English in the United Kingdom). However, with the increase of student mobility programs across Europe, such as ERASMUS, and the status of English as an International Language, another study abroad …

A Literature Review Of Wipe Sampling Methods For Pesticides In Published Exposure Measurement Studies In The United States, Christopher Michael Low

USF Tampa Graduate Theses and Dissertations

Pesticides in the United States are frequently used to control pests in many settings from residential homes to agricultural crops. Most pesticides, when used in accordance with their manufacturer's label are relatively safe, and will naturally degrade once exposed to the environment, however, these natural degradative processes can be hindered when introduced indoors. Furthermore, it has been shown that pesticides can easily bond to surface dislodgeable residues (SDRs) commonly known as dust. There are various methods that can be used to characterize the presence and exposure of pesticides indoors. Wipe sampling is one of the important methods commonly used to …

Protocol Guided Trace Analysis For Post-Silicon Debug Under Limited Observability, Yuting Cao Cao

USF Tampa Graduate Theses and Dissertations

This thesis considers the problem of reconstructing system level behavior of an SoC design from a partially observed signal trace. Solving this problem is a critical activity in post-silicon validation, and currently depends primarily on human creativity and insights. In this thesis, we provide algorithms to automatically infer system level flows from incomplete, ambiguous, and noisy trace data. This thesis also demonstrates the approach on two case studies, a multicore SoC model developed within the within the GEM5 environment, and a cycle accurate register transfer level model of a similar SoC design.

Leader Behavior Portfolios, Matthew Stephen Arbogast

USF Tampa Graduate Theses and Dissertations

Existing leadership theories and applied resources contain bountiful lists of recommended behaviors for leaders to employ, yet an integrated model that produces the most efficient set of leader behaviors does not currently exist. A standard, quantitative method to compare and contrast leader behaviors is needed to siphon utility from each resource, leading to an integrated and diversified set of optimal behaviors for leaders to consider. Leaders have limited time and need a reliable method to make informed behavioral decisions that consistently produce the most positive effects on the desired outcome. Unfortunately, leaders do not have the time to sift through …

The Effect Of Seasonality On Pulmonary Function Tests, Nicholas James Cotter

USF Tampa Graduate Theses and Dissertations

Lung spirometry data from three working-class industry populations were analyzed using logistic and linear regression to see if seasonality adversely affected test outcomes. Populations included emergency responders, general industry, and shipwrights. The data was organized into allergy and non-allergy seasons using NOAA meteorological data and regression and logistic analysis was run on these separate populations to test for demographic and seasonal effects on lung spirometry test outcomes. The American Thoracic Society gold standard was as a point for determining impaired lung function (FEV₁/FVC > 0.80). It was found that seasonality imparted a slight linear effect on the predictive values …

The Geophysical Kitchen Sink Approach To Improving Our Understanding Of Volcano-Tectonic Interactions, Ophelia Ann George

USF Tampa Graduate Theses and Dissertations

A multi-prong approach was taken in this dissertation to understand volcanic processes from both a long-term and more immediate hazard perspective. In the long-term, magma sources within the crust may produce measurable surficial response and long-wavelength gravity anomalies that provide information about the extent and depth of this magma. Long-term volcanic hazard forecasting is also improved by developing as complete a record as possible of past events. In the short-term, a long-standing question has been on the casting of precursory volcanic activity in terms of future volcanic hazards. Three studies are presented in this dissertation to address these issues. Inversion …

Sleep Disruption Among Cancer Patients Following Autologous Hematopoietic Stem Cell Transplantation, Ashley M. Nelson

USF Tampa Graduate Theses and Dissertations

Background: Sleep disruption is one of the most commonly reported quality of life concerns among cancer patients who have undergone hematopoietic stem cell transplantation (HSCT). Despite the high percentage of patients reporting sleep concerns, relatively little research has characterized sleep problems or explored relationships with psychological factors. In addition, no studies have used actigraph technology to characterize sleep issues among transplant recipients.

Method: Autologous HSCT recipients who were 6 to 18 months post-transplant were invited to participate. Patients completed self-report measures of cancer-related distress, fear of cancer recurrence, dysfunctional cognitions about sleep, and maladaptive sleep behaviors upon enrollment, wore an …

Emotional Self-Regulation: Voices And Perspectives Of Teachers Within Diverse Socio-Cultural Contexts, Anna Paula Peixoto Da Silva

USF Tampa Graduate Theses and Dissertations

Given the importance of emotional self-regulation to a child’s ability to develop social competence and prosocial behavior, and the significant role early childhood teachers play in supporting young children’s emotional self-regulation, it is important to explore the concept from the perspective of teachers, or from the socio-cultural context through which they (i.e., teachers) make sense of the world.

This study used an exploratory case study methodology to explore the understandings of emotional self-regulation among three Head Start teachers working with varying socio-cultural contexts and to identify the socio-cultural perspectives that influenced their ability to effectively apply their understandings.

Findings indicate …

Branding Implications Of Co-Created Social Responsibility, Alexander J. Kull

USF Tampa Graduate Theses and Dissertations

One of the most profound transformations of the marketing discipline in recent history has been driven by the democratization of power relations and value creation between brands and consumers. This dissertation explores the branding implications of this fundamental shift by investigating whether and how the type and degree of control shared by brands affect consumer empowerment perceptions and, in turn, consumer–brand relationships, as well as whether and how these effects might be moderated by the size and diversity of the choice set and by the image valence of the brand that shares control with consumers.

The present research examines such …

Moderation Analysis Of Bowel Function Among Nutrients And Physical Function Or Depression, As Well As Whether Bowel Function Is Related To Cognition In Older Adults, Jessie Alwerdt

USF Tampa Graduate Theses and Dissertations

As we age, the risk for gut issues, such as smooth muscle tone, may be an underlying indirect or direct cause or risk factor for many age-related issues, such as frailty. Consequences of decreased motility and depleted epithelial barrier may result in nutrient deficiencies that may increase the risk for malnutrition (Brownie, 2006). Further, there is increasing evidence that there is a gut-brain-axis relationship that may influence cognition and mental health issues, such as depression and anxiety. While there are relationships established, the interconnections of these factors have yet to be fully understood.

This dissertation examined several relationships specific to …

Material Expertise: Applying Object-Oriented Rhetoric In Marine Policy, Zachary Parke Dixon

USF Tampa Graduate Theses and Dissertations

This dissertation applies object-oriented rhetorics and posthuman philosophies to environmental policy deliberation in order to help bridge gaps between policy makers, scientists, and citizens. For environmental policy scholars the non-credentialed expertise of local, or indigenous stakeholders is valued as possessing technical, objective merit that can improve the development and implementation of environmental policies. However, the utilization of stakeholder expertise in environmental policy faces serious challenges in terms of finding common grounds for communication within complex techno-social systems, of overcoming deep cultural differences and perceptions, and grave ethical issues of access and power. This dissertation develops two case studies of marine …

Examining Student And Teacher Perceptions Of The Classroom Social Environment Across School Context: Effects Of Individual Factors, Keri Stewart

USF Tampa Graduate Theses and Dissertations

Although teachers and students are the primary actors in the classroom environment, they often have different perceptions of the instructional and relational aspects of the classroom. Despite these differences, research indicates perceptions of the quality of the classroom social environment have implications for both student and teacher outcomes. Additionally, research has indicated the differences in perceptions occur not only between students and teachers, but also among individual students within classrooms. The extent and the manner in which these perceptions converge may vary across different class and school contexts. School and class context, as well as individual characteristics and beliefs have …

The Effect Of Presentation Format On Investor Judgments And Decisions: Does The Effect Differ For Varying Task Demands?, Kevin Agnew

USF Tampa Graduate Theses and Dissertations

This study examines the efficacy of presenting footnotes information in alternative display formats on investors’ judgments and decisions. Non-professional investors play a significant role in the capital markets yet they do not always attend to information contained in footnote disclosures. As a result, nonprofessional investors systematically misprice firms and misallocate resources. Recognizing that increased mandatory and voluntary disclosures create additional challenges for non-professional investors, both the FASB and SEC have actively sought ways to increase the effectiveness of disclosures. I hypothesize that high display proximity, low signal-to-noise presentation formats can increase investors’ attention to and processing of footnote disclosures and …

Drivers Of Immune Cost And Implications For Host Protection From Parasites, Amber Jasmine Brace

USF Tampa Graduate Theses and Dissertations

Among species, populations, and individuals, there exists a tremendous amount of variation in how hosts respond to, and are thus protected from parasites. Such variation inevitably affects host-parasite dynamics and ultimately how parasites will move through and evolve in communities. A likely factor in the diversity of immune responses seen in nature are the costs associated with activation of the immune system upon exposure to parasites. Costs can manifest in many ways, including changes in resource usage or metabolism, self-damage from inflammatory reactions, lost opportunities (e.g., foraging reproduction), and often as tradeoffs with other physiological processes. However, we do not …

Rupturing The World Of Elite Athletics: A Feminist Critical Discourse Analysis Of The Suspension Of The 2011 Iaaf Regulations On Hyperandrogenism, Ella Browning

USF Tampa Graduate Theses and Dissertations

In 2011 the International Association of Athletic Federations (IAAF) published the Regulations on Hyperandrogenism, a health policy banning female athletes from track and field competition if their natural levels of testosterone were found to be higher than those of most female athletes. In 2014, Dutee Chand, a sprinter from India, was banned from competition based on these regulations. She appealed her ban in the Court of Arbitration for Sport (CAS) and as a result the 2011 IAAF Hyperandrogenism Regulations were suspended for two years. The issues at stake in the suspension of these regulations are, at their core, rhetorical issues …

The Relationship Of Attributions And Parental Characteristics With Parental Problem Recognition, Lindsey Heath Steding

USF Tampa Graduate Theses and Dissertations

A significant number of youth experience mental health disorders for which they suffer negative consequences. Although there are evidence-based therapies available to help children and their families, most youth do not receive treatment. Parental problem recognition is likely a primary barrier in this process. This study begins to address why parents may have difficulty recognizing mental health problems by extending existing models and integrating evidence about parental perceptions. Specifically, the study aimed to investigate the relationship between parental attributions and parents’ problem determination, and to examine the influence that parental characteristics have on this judgment process. Participants included 164 parents …

Phenomenology And The Crisis Of Contemporary Psychiatry: Contingency, Naturalism, And Classification, Anthony Vincent Fernandez

USF Tampa Graduate Theses and Dissertations

This dissertation is a contribution to the contemporary field of phenomenological psychopathology, or the phenomenological study of psychiatric disorders. The work proceeds with two major aims. The first is to show how a phenomenological approach can clarify and illuminate the nature of psychopathology—specifically those conditions typically labeled as major depressive disorder and bipolar disorder. The second is to show how engaging with psychopathological conditions can challenge and undermine many phenomenological presuppositions, especially phenomenology’s status as a transcendental philosophy and its corresponding anti-naturalistic outlook.

In the opening chapter, I articulate the three layers of the subject matter of phenomenological research—what I …
