A Person-Centered Approach Of Dynamic Needs: Demographic Characteristics, Static Factors, And Justice-Related Outcomes Among Juvenile Offenders In Florida, Caitlin Brady Jan 2020

A Person-Centered Approach Of Dynamic Needs: Demographic Characteristics, Static Factors, And Justice-Related Outcomes Among Juvenile Offenders In Florida, Caitlin Brady

Electronic Theses and Dissertations, 2020-2023

Prior research examining criminogenic risk and need suggests that dynamic factors (i.e., criminogenic needs) are best suited for intervention and treatment as they are changeable over time. Thus, dynamic factors can be targeted to reduce the likelihood of recidivism among youth in the juvenile justice system. The assessment of needs is critical as it allows for the prediction of future delinquency and the ability to provide appropriate services/treatment for juvenile offenders. Several studies have shown that youth present with multiple needs and that these needs differ by gender. Therefore, the current study utilized a sample of adjudicated youth under community …

Midwave Vs Longwave Infrared Search And Track And Aerosol Scattering Target Acquisition Performance, Steven Butrimas

Electronic Theses and Dissertations, 2020-2023

The decision on whether to use a mid wave infrared (MWIR) or long wave infrared (LWIR) sensor for a given task can be a formidable verdict. The scope entails facts about the observable source, the atmospheric interactions, and the sensor parameters within the hardware device. Even when all the individual metrics are known, the combination ultimately determines whether a MWIR or LWIR sensor is more appropriate. Despite the vast number of variables at play, the reduction of inputs through focused studies can provide essential insight into MWIR and LWIR comparisons. This dissertation focuses on the roles of point source target …


Cute Panda Or Evil Dragon? Market Economy, Conflict Behavior And China's Peaceful Rise, Xiongwei Cao Jan 2020

Cute Panda Or Evil Dragon? Market Economy, Conflict Behavior And China's Peaceful Rise, Xiongwei Cao

Electronic Theses and Dissertations, 2020-2023

China has two contrasting images in the West: a cute panda and an evil dragon. In recent years, a near-consensus seems to be forming among policy makers in Washington that the People's Republic of China (PRC) is more of an evil dragon than a cute panda, using "sharp power" to threaten U.S. interests and world peace. The PRC is regarded by the current U.S. administration as a "strategic competitor," and a new Cold War seems to be looming between the world's two largest economies. Is the rise of China destined to cause conflicts or even war? After analyzing the conflict …


Early Host Defense Mechanisms Against La Crosse Virus Infection, Maria A. Cruz Zamora Jan 2020

Early Host Defense Mechanisms Against La Crosse Virus Infection, Maria A. Cruz Zamora

Electronic Theses and Dissertations, 2020-2023

Given the importance of innate defense mechanisms in the skin, we have examined the interactions of the arbovirus La Crosse virus (LACV) with serum factors that serve as a first line of antiviral defense, and the outcome of LACV infection of human keratinocytes, one of the main cell types present at viral entry. Incubation of LACV derived from insect cells (I-LACV) with normal human serum in vitro did not result in neutralization, but instead stabilized LACV virions and enhanced infectivity. Enhanced infectivity was also seen with heat inactivated serum devoid of complement activity and with serum from a range of …


Navigating Immersive And Interactive Vr Environments With Connected 360° Panoramas, Samuel Cosgrove Jan 2020

Navigating Immersive And Interactive Vr Environments With Connected 360° Panoramas, Samuel Cosgrove

Electronic Theses and Dissertations, 2020-2023

Emerging research is expanding the idea of using 360-degree spherical panoramas of real-world environments for use in "360 VR" experiences beyond video and image viewing. However, most of these experiences are strictly guided, with few opportunities for interaction or exploration. There is a desire to develop experiences with cohesive virtual environments created with 360 VR that allow for choice in navigation, versus scripted experiences with limited interaction. Unlike standard VR with the freedom of synthetic graphics, there are challenges in designing appropriate user interfaces (UIs) for 360 VR navigation within the limitations of fixed assets. To tackle this gap, we …


An Information-Potential Approach To Airborne Lidar Point Cloud Sampling And Assessment, Kristian Damkjer Jan 2020

An Information-Potential Approach To Airborne Lidar Point Cloud Sampling And Assessment, Kristian Damkjer

Electronic Theses and Dissertations, 2020-2023

In the last decade, airborne laser scanning (ALS) systems have evolved to provide increasingly high-fidelity topographic mapping data. Point clouds and derivative models now rival photogrammetrically-derived equivalents. Yet, despite technological advancement and widespread adoption of light detection and ranging (LiDAR) data, sampling guidance and data quality (DQ) assessment remains an open area of research due to the volumetric and irregularly sampled nature of point clouds and the persistent influence of assumptions from early point scanning LiDAR systems on assessment methods. This dissertation makes several contributions to the research area by considering point cloud sampling strategies and DQ assessment from an …

Electronic Theses and Dissertations, 2020-2023

This thesis applies a new methodology to dietary reconstructions of a unique population excavated from Kellis 2, a Romano-Christian era (c.50-450 AD) cemetery located in the ancient city of Kellis, Dakhleh Oasis, Egypt. Previously, stable carbon and nitrogen isotope analyses were conducted on bulk hair keratin from 216 individuals to examine their dietary practices and health status. Although this research identified the presence of specific dietary choices in the community, the researchers were not able to determine what fraction of the diet was composed of those resources. This is the first such study to use a priori dietary reconstruction data …


Viscoelastic Analysis Of High Strain Composites For Deployable Structures In Space Applications, Andrew Gomez-Delrio Jan 2020

Viscoelastic Analysis Of High Strain Composites For Deployable Structures In Space Applications, Andrew Gomez-Delrio

Electronic Theses and Dissertations, 2020-2023

Thin-ply composite laminates capable of enduring high strains are currently under investigation for compliant deployable spacecraft structures. Deployable structures such as booms fabricated from these materials can be flattened and coiled to high curvatures, achieving a compact configuration for stowage. Once in orbit, they are released with minimal actuation for deployment, allowing the operational geometry to be recovered. Previous studies have shown that the viscoelastic properties of the composite epoxy matrix can negatively impact final shape accuracy due to stress relaxation during stowage. In addition, since the strain energy stored is relied upon for deployment, considerable relaxation can potentially result …

Annotating base-pairing interactions is one of the critical steps …


Investigating The Inclusiveness Of Stem Courses And Reducing Barriers By Using The Universal Design For Learning Framework, Westley James Jan 2020

Investigating The Inclusiveness Of Stem Courses And Reducing Barriers By Using The Universal Design For Learning Framework, Westley James

Electronic Theses and Dissertations, 2020-2023

Students with disabilities are in postsecondary STEM courses and degree programs, but only a few studies have investigated how STEM courses can be designed to support students with disabilities. We began addressing this gap by interviewing students with diagnoses characterized by variations in executive functions about their experiences in postsecondary STEM courses. We analyzed the interviews through a social relational perspective of disability as this allowed us to identify how course structures disable students from effective engagement with STEM courses. We found STEM courses present heightened barriers compared to non-STEM courses, with common barriers including a lack of resources and …


Towards Scalable Network Traffic Measurement With Sketches, Rhongho Jang Jan 2020

Towards Scalable Network Traffic Measurement With Sketches, Rhongho Jang

Electronic Theses and Dissertations, 2020-2023

Driven by the ever-increasing data volume through the Internet, the per-port speed of network devices reached 400 Gbps, and high-end switches are capable of processing 25.6 Tbps of network traffic. To improve the efficiency and security of the network, network traffic measurement becomes more important than ever. For fast and accurate traffic measurement, managing an accurate working set of active flows (WSAF) at line rates is a key challenge. WSAF is usually located in high-speed but expensive memories, such as TCAM or SRAM, and thus their capacity is quite limited. To scale up the per-flow measurement, we pursue three thrusts. …


Neurophysiological Correlates Of Trust In Robots, Theresa Kessler Jan 2020

Neurophysiological Correlates Of Trust In Robots, Theresa Kessler

Electronic Theses and Dissertations, 2020-2023

This work is designed to address the questions as to what drives and collapses trust between a human and a robot. Such information is needed to properly design automated decision aids. Human-robot trust (HRT) has traditionally been measured by questionnaires, which can be subject to lack of participant understanding, disengagement, and dishonesty. Therefore, implicit measures of trust are needed to measure HRT. The goal here is to identify neuro-physiological underpinnings (implicit measures) for HRT to assist designers in the development of automated robotic aids. More specifically, experiment one, looked to determine the effects of witnessing robot error on skin conductance …


Two Pink Lines: Exploring Florida's Pregnancy-Associated Intimate Partner Homicides, Sonya Spence Jan 2020

Two Pink Lines: Exploring Florida's Pregnancy-Associated Intimate Partner Homicides, Sonya Spence

Electronic Theses and Dissertations, 2020-2023

Pregnancy-associated Homicides (PAHs) are homicides committed while a woman is pregnant, and recent reports from Florida's Pregnancy-associated Mortality Review (PAMR) suggest that it is a leading cause of unnatural deaths for pregnant women. However, a study has not examined the motives, characteristics, and underlying factors behind these homicides. Therefore, this study explored Florida's Pregnancy-associated Intimate Partner Homicides (PAIPHs) using a sample of women that were reportedly pregnant at the time of their mortality (n=33), as well as a comparison group of not-pregnant women (n=33). To conduct the study, reported homicide data from news sources, police reports, and other public records …


Household Economies And Socioeconomic Integration: An Analysis Of Obsidian Artifacts From Coba, Quintana Roo And Yaxuna, Yucatan, Mexico, Danielle Waite Jan 2020

Household Economies And Socioeconomic Integration: An Analysis Of Obsidian Artifacts From Coba, Quintana Roo And Yaxuna, Yucatan, Mexico, Danielle Waite

Electronic Theses and Dissertations, 2020-2023

Using Handheld XRF (X-Ray Fluorescence), this thesis explores how household economies at two Maya archaeological sites, Coba and Yaxuna, differed during a period of expansion and integration from the Early to Late Classic transition period (A.D. 500-750/800). Previous research suggests that during this time, Yaxuna was under the direction of Coba, however, due to the lack of household archaeology at both sites, how the bridging of these two centers impacted households and their domestic economies remains unknown. A compositional analysis of 1,186 obsidian artifacts recovered by the Proyecto de Interaccion Politica del Centro de Yucatan and the Proyecto Sacbe Yaxuna-Coba …


Rotational And Shower Head Cooling Hole Effects On Leading-Edge Jet Impingement Heat Transfer, Weston Olson Jan 2020

Rotational And Shower Head Cooling Hole Effects On Leading-Edge Jet Impingement Heat Transfer, Weston Olson

Electronic Theses and Dissertations, 2020-2023

Jet Impingement and shower head cooling are critical cooling techniques used to maintain turbine blades at operational temperatures. Jet impingement is extremely effective at removing large amounts of heat flux from the target surface, the inner blade wall, through stagnation point heat transfer. Shower head cooling produces a cooling film around the exterior of the blade, in return reducing external heat flux. The current work consisted of investigating the jet impingement effectiveness with rotational effects for two different cooling schemes. The analysis was conducted numerically using STAR CCM+ with two different turbulence models, the three equation Lag Elliptic Blending K …


Design Of Ternary Operations Utilizing Flow-Based Computing, James Pyrich Jan 2020

Design Of Ternary Operations Utilizing Flow-Based Computing, James Pyrich

Electronic Theses and Dissertations, 2020-2023

The development of algorithms and circuit designs that exploit devices that have the ability to persist multiple values will lead to alternative technologies to overcome the issues caused by the end of Dennard scaling and slowing of Moore's Law. Flow-based designs have been used to develop binary adders and multipliers. Data stored on non-volatile memristors are used to direct the flow of current through nanowires arranged in a crossbar. The algorithmic design of the flow-based crossbar is fast, compact, and efficient. In this paper, we seek to automate the discovery of flow-based designs of ternary circuits utilizing memristive crossbars.


Towards Robust Artificial Intelligence Systems, Sunny Raj Jan 2020

Towards Robust Artificial Intelligence Systems, Sunny Raj

Electronic Theses and Dissertations, 2020-2023

Adoption of deep neural networks (DNNs) into safety-critical and high-assurance systems has been hindered by the inability of DNNs to handle adversarial and out-of-distribution input. State-of-the-art DNNs misclassify adversarial input and give high confidence output for out-of-distribution input. We attempt to solve this problem by employing two approaches, first, by detecting adversarial input and, second, by developing a confidence metric that can indicate when a DNN system has reached its limits and is not performing to the desired specifications. The effectiveness of our method at detecting adversarial input is demonstrated against the popular DeepFool adversarial image generation method. On a …


The Susceptibility Of Deep Neural Networks To Natural Perturbations, Mesut Ozdag Jan 2020

The Susceptibility Of Deep Neural Networks To Natural Perturbations, Mesut Ozdag

Electronic Theses and Dissertations, 2020-2023

Deep learning systems have achieved great success in various types of applications in recent years. They are increasingly being adopted for safety-critical tasks such as face recognition, surveillance systems, speech recognition, and autonomous driving. On the other hand, it has been found that deep neural networks (DNNs) can easily be fooled by adversarial input samples. These imperceptible perturbations on images can lead any machine learning system to misclassify the objects with high confidence. Furthermore, they can be almost indistinguishable to a human observer. These systems can also be exposed to adverse weather conditions such as fog, rain, and snow. This …


Why Experienced Incivility Triggers Instigated Incivility: Combining The Affect-Based And Resource-Based Pathways, Xin Peng Jan 2020

Why Experienced Incivility Triggers Instigated Incivility: Combining The Affect-Based And Resource-Based Pathways, Xin Peng

Electronic Theses and Dissertations, 2020-2023

Ever since Andersson and Pearson's seminal work (1999), incivility has become one of the most commonly studied forms of mistreatment in the organizational sciences (Hershcovis, 2011). While research to date has yielded significant findings about the effects of experienced incivility, far less is known about the underlying mechanisms that linked experienced incivility and instigated incivility. Among the limited studies investigating the positively relationship between experienced incivility and instigated incivility, two distinct theoretical frameworks, affective-based perspective and resource-based, were drew upon. And these two perspectives have never been examined in the same model. To this end, I investigated negative affect (affect-based …

Removal Of Heavy Metals From Landfill Leachate Using Electrospun Polyelectrolyte Complex Fiber-Laminated Ultrafiltration Membrane, Amirsalar Rabbani Esfahani

Electronic Theses and Dissertations, 2020-2023

Ultrafiltration (UF) is a low-pressure membrane process that yields higher permeate flux and saves significant operating costs compared to NF/RO. However, UF has not been applied as a primary method for landfill leachate treatment due to its large pore size. This research investigated the removal of heavy metals from landfill leachate using an UF membrane laminated with fiber mats produced from electrospinning of a polyelectrolyte complex. In this research, we modified the surface of the UF membrane with two polyelectrolytes including Polyacrylic Acid (PAA) and Polyallylamine Hydrochloride (PAH). The removal of heavy metals including Pb, Cd, and Cu from water …
