Comparative Study Of Model-Based And Learning-Based Disparity Map Fusion Methods, Douglas E. Kerr Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

Creating an accurate depth map has several, valuable applications including augmented/virtual reality, autonomous navigation, indoor/outdoor mapping, object segmentation, and aerial topography. Current hardware solutions for precise 3D scanning are relatively expensive. To combat hardware costs, software alternatives based on stereoscopic images have previously been proposed. However, software solutions are less accurate than hardware solutions, such as laser scanning, and are subject to a variety of irregularities. Notably, disparity maps generated from stereo images typically fall short in cases of occlusion, near object boundaries, and on repetitive texture regions or texture-less regions. Several post-processing methods are examined in an effort to …

Development Of An Activity-Based Windowing Approach To Evaluate Real-World Nox Emissions From Modern Medium And Heavy-Duty Diesel Trucks, Rasik Pondicherry

Graduate Theses, Dissertations, and Problem Reports (ETD)

The introduction of in-use emissions regulations by the United States Environmental Protection Agency (U.S.EPA) requires medium-duty (MD) and heavy-duty (HD) engine manufacturers to demonstrate emissions compliance during in-fleet operation. In the United States (U.S.), the Not-to-Exceed (NTE) method is used to evaluate real-world emissions compliance from on-highway MD and HD trucks. Regulatory agencies, engine manufacturers and research entities have identified that the NTE method incorporates numerous exclusions and evaluates emissions compliance only under selective operating conditions that are favorable for the selective catalytic reduction (SCR) system to reduce oxides of nitrogen (NOx) emissions efficiently. Such operation is typically encountered only …

Alternative Media And Mulches In Organic Vegetable Production, Heather R. Griffith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Reducing or eliminating waste from organic vegetable production can conserve money as well as resources. Conventional greenhouse production of vegetable transplants often relies on abundant fertigation which produces large amounts of polluted runoff, and the field production of organic vegetables frequently relies on the use of polyethylene mulch. A greenhouse study was conducted to determine if organic transplants can be successfully produced in a greenhouse under reduced soil moisture in order to reduce leaching of nutrients and potential water pollution. To test this, we compared the effect of reduced irrigation volumes to the standard practice of irrigating with 120% of …

Comparison Of Skeletal And Dentoalveolar Changes Between Two Bone-Borne Maxillary Expanders, Mohamad Sarraj

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Bone-borne maxillary expander (BBME) are designed to provide additional anchorage to widen the maxillary arch for patients who exhibit maxillary transverse deficiency. One form of BBME is the hybrid BBME which uses mini-implants (bone-borne) and posterior teeth (tooth-borne) as anchorage for maxillary expansion. The other form of BBME is absolute BBME which only uses mini-implants as anchorage. It is not clear in the literature if there is a difference in skeletal and dental changes with these two types of expanders. The objective of this study was to compare the skeletal, dentoalveolar, and periodontal changes between the hybrid and the …

Spatio-Temporal Analysis Of Crime Incidents For Forensic Investigation, Jamie Spencer Spaulding

Graduate Theses, Dissertations, and Problem Reports (ETD)

Crime analysis and mapping has been routinely employed to gather intelligence which informs security efforts and forensic investigations. Traditionally, geographic information systems in the form of third-party mapping applications are used for analysis of crime data but are often expensive and lack flexibility, transparency, or efficiency in uncovering associations and relationships in crime. Each crime incident and article of evidence within that incident has an associated spatial and temporal component which may yield significant and relevant information to the case. Wide variations exist in the techniques that departments use and commonly spatial and temporal components of crime are evaluated independently, …

Representation Learning With Adversarial Latent Autoencoders, Stanislav Pidhorskyi M.S.

Graduate Theses, Dissertations, and Problem Reports (ETD)

A large number of deep learning methods applied to computer vision problems require encoder-decoder maps. These methods include, but are not limited to, self-representation learning, generalization, few-shot learning, and novelty detection. Encoder-decoder maps are also useful for photo manipulation, photo editing, superresolution, etc. Encoder-decoder maps are typically learned using autoencoder networks.
Traditionally, autoencoder reciprocity is achieved in the image-space using pixel-wise
similarity loss, which has a widely known flaw of producing non-realistic reconstructions. This flaw is typical for the Variational Autoencoder (VAE) family and is not only limited to pixel-wise similarity losses, but is common to all methods relying upon …

Programming Of Floating-Gate Transistors For Nonvolatile Analog Memory Array, Haifa Abulaiha

Graduate Theses, Dissertations, and Problem Reports (ETD)

Since they were introduced, floating-gate (FG) transistors have been used as non-volatile digital memory. Recent research has shown that floating-gate transistors can be successfully used as analog memory, specifically as programmable voltage and current sources. However, their proliferation has been limited due to the complex programming procedure and the complex testing equipment. Analog applications such as field-programmable analog arrays (FPAAs) require hundreds to thousands of floating-gate transistors on a single chip which makes the programming process even more complicated and very challenging. Therefore, a simplified, compact, and low-power scheme to program FGs are necessary. This work presents an improved version …

Searches For Fast Radio Bursts Using Machine Learning, Devansh Agarwal

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fast Radio bursts (FRBs) are enigmatic astrophysical events with millisecond durations and flux densities in the range 0.1-100 Jy, with the prototype source discovered by Lorimer et al. (2007). Like pulsars, FRBs show the characteristic inverse square sweep in observing frequency due to propagation through an ionized medium. This effect is quantified by the dispersion measure (DM). Unlike pulsars, FRBs have anomalously high DMs, which are consistent with an extragalactic origin. Over 100 FRBs have been published at the time of writing, and 13 have been conclusively identified with host galaxies with spectroscopically determined redshifts in the range 0.003 ≤ …

The Fight Is Still On: An Ethical Analysis Of The American Civil Liberties Union’S Partisan Rhetoric In The Trump Era, Emily Charlotte Gerber

Graduate Theses, Dissertations, and Problem Reports (ETD)

The 2016 U.S. presidential election of Donald Trump generated a newfound surge in political advocacy that greatly benefitted certain nonprofits and grassroots organizations. One of these organizations was the American Civil Liberties Union, a nonpartisan nonprofit dedicated to protecting and defending civil liberties and rights in the U.S. The ACLU received an unprecedented number of donations following Election Day and has since pursued an aggressive campaign against President Donald Trump.

In order to explore this phenomenon, this thesis analyzed the ACLU’s rhetoric between Presidents George W. Bush and Donald Trump (both Republicans) and between Presidents Barack Obama (Democrat) and Donald …

The Use Of Differing Verb Types In The Oral Narratives Of School-Age Children, Allison Ann Switzer

Graduate Theses, Dissertations, and Problem Reports (ETD)

The aim of this project was to examine the use of action, metacognitive, and metalinguistic verbs in narratives relative to age-related growth for children with typical language and their peers with a language-based disorder. While limited information is known about the use of these differing verb types, there is evidence to show that metacognitive and metalinguistic verbs are less salient than action verbs, and therefore have a longer trajectory of acquisition. The oral narratives of 84 typically developing students were coded for occurrences of action verbs, metacognitive verbs, and metalinguistic verbs to obtain a total use as well as to …

Exploring The Challenges Of Social Integration Within An Upper-Level Public Relations Classroom, Tabitha Hayley Dyer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite three decades of literature that has explored the gender imbalance of public relations at a professional level, there is a dearth of information addressing if or how these experiences are informed at a collegiate level. Accordingly, this study examines if the gender imbalance impacts students in the upper-level public relations classroom, and the similarities and differences exist between other single-gender dominant programs including nursing and Science, Technology, Engineering, and Mathematics (STEM) using three dimensions (i.e., role strain, teamwork, and overall social environment) as a comparison.

Graduate Theses, Dissertations, and Problem Reports (ETD)

The oxygen transport kinetics of the electrodes of Solid Oxide Fuel Cells (SOFC) are critical properties to achieve higher efficiencies in the cell. (La0.60Sr0.40)0.95Co0.20Fe0.80O3-x (LSCF) is a mixed ion-electron conductor material that is expected to be optimized and utilized as the cathode of the SOFC’s. The reason for LSCF to be considered as the next cathode material for SOFC is due to its high ionic and electronic conductivities, and high oxygen transport kinetics. Additionally, to the excellent properties that this material offers, it has been seen that the kinetic properties of the material can be further optimized by adding a …

Monotonic Response Of Rc Exterior Beam-Column Joints Reinforced With Filler-Modules And Frp Composite Wraps/Gussets, Praveen Kumar Reddy Majjigapu

Graduate Theses, Dissertations, and Problem Reports (ETD)

A review of post-earthquake reconnaissance studies revealed that reinforced concrete (RC) structures, designed and built before the development of Uniform Building Code (UBC) seismic design guidelines in 1976, have suffered complete collapse or severe damages due to the brittle failure of exterior beam-column joints. Over the past 50 years, several studies were conducted to strengthen exterior joints of in-service structures, with limited emphasis on developing simple, economic and durable repair strategies to improve energy absorption through large inelastic joint deformations. Even less emphasis was devoted to developing repair procedures that minimize stress-concentrations at joint corners and enhancing the strength, ductility, …

Addiction Or Disorder? Using The Bias Map Model To Explain The Stigmatizing Effects Of News Media Labels For Opioid Use Disorder, Kylie J. Wilson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The stigma surrounding opioid use disorder is often reinforced by the language that the general public and institutions use to talk about people with the disorder. Consistent with labeling theory, contending that labels are vehicles for social categorization and stereotypes, triggering bias, (e.g., Ashford, Brown, Ashford, & Curtis, 2019; Corrigan, Kuwabara, & O’Shaughnessy, 2009; Goodyear, Haass-Koffler, & Chavanne, 2018; Link & Phelan, 1999) but the ingroup based cognitive and emotional process through which these affect public stigma has not been explored in detail. This dissertation employs the Stereotype Content Model (SCM) and the Behaviors from Intergroup Affect Stereotypes (BIAS) Map …

Validation Of Fast Spectrochemical Screening Methods For The Identification Of Counterfeit Pharmaceutical Packaging, Emily Ann Haase

Graduate Theses, Dissertations, and Problem Reports (ETD)

Counterfeit pharmaceuticals are an actively developing health and economic threat worldwide. Particularly prevalent are counterfeit pharmaceuticals distributed in emerging nations and through internet pharmacies or e-pharmacies. Although technology has been developed that discourages anti-counterfeiting practices (such as optically variable devices, invisible ink, and track-and-trace technology), it remains somewhat novel and expensive to implement on a widespread scale.

In this study, Laser Induced Breakdown Spectroscopy (LIBS) and Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR) were proposed as fast and non-invasive tools for the identification of counterfeit pharmaceutical packages. The main objective of this research was to develop and evaluate the capabilities …
