Using Facial Recognition For Selective Pose Detection, William J. Parker Jul 2025

Using Facial Recognition For Selective Pose Detection, William J. Parker

Master's Theses

Pose detection involves locating and identifying key body points for all individuals within a frame. This enables the ability to convert the pose into a digital format, which can then be recorded and analyzed for a variety of purposes. Advancements in the field have already opened applications in areas such as digital fitness coaches, fall detection, and virtual reality. Existing approaches primarily focus on tracking all detected individuals, which limits the practical applications when attempting to analyze a single or specific subject when there are other people in frame.

Sirilla: Predicting Traffic Flow Via Stacked Decentralized Federated Learning, Andrew Selvia Jul 2025

Sirilla: Predicting Traffic Flow Via Stacked Decentralized Federated Learning, Andrew Selvia

Master's Theses

Billions of people today rely on traffic predictions to optimize their travels. Digital mapping services deliver accurate predictions by learning from vast troves of historical data. Impressive as these systems are, their assumptions do not always apply. They depend on an endless flow of sensitive user data to a central authority, a stable Internet connection, and trustworthiness on both sides of the traditional client-server model. This thesis explores a novel architecture which bucks those assumptions. In the proposed model, traffic data remains on edge devices which individually train models via federated learning.

Genotoxicity Assessment Of Conventional And Cad/Cam Denture Base Materials, Alanood Aldubayan

Master's Theses (2009 -)

Aim: In prosthodontics, polymethyl methacrylate (PMMA) has been widely used. Their biocompatibility and potential genotoxicity remain a concern due to the residual monomer release. Computer-aided design and manufacturing (CAD/CAM) denture base materials have emerged and offered some improved mechanical and physical properties compared to the standard conventional heat-cured denture base material. However, their long-term biocompatibility remains unstudied. Therefore, this study evaluates the genotoxicity effects of conventional and CAD/CAM denture base materials on human gingival fibroblasts (HGFs). Methodology: Disk-shaped samples were fabricated of six denture base resins, including heat-cured PMMA, milled PMMA, and four 3D-printed resins. HGFs were exposed to the …

Deciphering The Apomixis Reproductive Trait And Its Manipulation Strategies To Enhance Crop Improvement, Mohd Razik Midin, Aiesyaa Majdiena Emlee, Mohamad Azimi Shaharudin, Fadzlin Qistina Fauzan, Siti Fatimah Zakaria, Emelda Rosseleena Rohani, Farah Ayuni Farinordin

Turkish Journal of Botany

In plants, apomixis is the process of asexual reproduction when seeds are produced from the maternal tissues of the ovule. Gametophytic and sporophytic apomixis develop with distinctive mechanisms and are molecularly triggered either by hybridization or polyploidization. As apomixis involves meiosis suppression and parthenogenesis, these events are likely to be genetically driven. T he apomictic trait is associated with several genes that need a diploid or aneuploid gamete for their transfer in polyploid species. T he molecular mechanisms driving apomixis in various plant species have been explained by previous investigations into apomictic genes. Apomixis offers agronomic advantages, such as reducing …

Safeguarding Intellectual Property: A Strategic Imperative For Organizations, Alan Saquella

Publications

Intellectual property (IP) is more than a legal concept — it is the foundation of innovation and the engine that drives growth, differentiation, and long-term success. From proprietary algorithms to product designs, trade secrets, and customer data, IP represents the most valuable asset many organizations possess. When compromised, the damage can be severe — manifesting in lost revenue, competitive disadvantage, reputational harm, and in some cases, the collapse of entire business lines.

Deformation And Earthquake Potential On The North America - Caribbean - Cocos Triple Junction In Guatemala, Jeremy Maurer, Andreas Eckert, Qiaoqi Sun, Jonathan Obrist-Farner

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The triple junction between the Cocos (CO), North American (NA), and Caribbean (CA) tectonic plates in Guatemala is a region of high seismic risk and includes many large faults and historic earthquakes. Previous analyses of the tectonic system have been overly simplified, resulting in discrepancies between geologically derived and geodetic models of fault slip rate. This study leverages available geodetic, seismic, and geologic data to develop new strain rate maps and faulting models for the region. We find that locking on the regional faults matches historic reports of large earthquakes and that multiple minor fault segments are active and accommodate …

Unusually Preserved Benthic Foraminiferal Assemblages From The Lower Triassic Virgin Limestone Member, Moenkopi Formation, Nevada, U.S.A, Sara B. Pruss, Teagan E. Mcguire

Geosciences: Faculty Publications

The end-Permian mass extinction, the largest in Earth’s history, was so severe that biotic recovery was delayed for five or more million years. During the Early Triassic, ecosystems were populated by low diversity fauna, and the taphonomy of some fossil groups was reminiscent of Cambrian small shelly-style preservation. Herein we report a new assemblage of benthic foraminifera from the Lower Triassic (Olenekian, Spathian) Virgin Limestone Member, Moenkopi Formation in southern Nevada. Insoluble residues of carbonate samples produced >80 benthic foraminiferal tests, preserved as apatite- and iron oxide-internal molds. Dominant morphological groups include planispiral evolute forms, uniserial forms with round chambers, …

Pharmacy Faculty Articles and Research

Thyroid hormones (thyroxine, T4, and triiodothyronine, T3) are indispensable for sustaining vertebrate life, and their deficiency gives rise to a wide range of symptoms characteristic of hypothyroidism, affecting 5–10% of the world’s population. The precursor for thyroid hormone synthesis is thyroglobulin (Tg), a large iodoglycoprotein consisting of upstream regions I-II-III (responsible for synthesis of most T4) and the C-terminal CholinEsterase-Like (ChEL) domain (responsible for synthesis of most T3, which can also be generated extrathyroidally by T4 deiodination). Using CRISPR/Cas9-mediated mutagenesis, we engineered a knock-in of secretory ChEL into the endogenous TG …

Immune checkpoint inhibitors (ICIs), either as monotherapy (ICI-Mono) or combined with chemotherapy (ICI-Chemo), improves survival in advanced non-small cell lung cancer (NSCLC). However, prospective guidance for choosing between these options remains limited, and single-feature biomarkers like PD-L1 prove inadequate. We develop a machine learning model using clinicogenomic data from four cohorts (MD Anderson n = 750; Mayo Clinic n = 80; Dana-Farber n = 1077; Stand Up To Cancer n = 393) to predict individual benefit from adding chemotherapy. Benefit scores are calculated using five distinct functions derived from 28 genomic and 6 clinical features. Our integrated model, A-STEP (Attention-based …

Conjugative Delivery Of Toxin Genes, Yang Grace Li, Daniel Haeusser, William Margolin, Peter J Christie

Faculty, Staff and Student Publications

The bacterial type IV secretion systems (T4SS) are medically problematic for their roles in the dissemination of mobile genetic elements or effector proteins, but they also have great potential for new antimicrobial therapies. Recent studies have deployed the T4SS subfamily of conjugation systems to deliver gene editing CRISPR/Cas systems to disrupt drug resistance genes or kill targeted bacterial recipients. However, the therapeutic potential of conjugative CRISPR/Cas delivery is compromised by mutations or host repair systems that diminish the efficiency with which CRISPR/Cas induces double-strand breaks in new transconjugants. Here, we compared the efficiencies of conjugation-based killing systems based on the …

Energetic And Economic Aspects Of Rebound, Part Ii: Applications Of The Framework, Matthew Kuperus Heun, Gregor Semieniuk, Paul E. Brockway

University Faculty Publications and Creative Works

Widespread implementation of energy efficiency is a key greenhouse gas emissions mitigation measure, but rebound can “take back” energy savings. However, the absence of solid analytical foundations hinders empirical determination of rebound magnitudes. In Part I, we developed foundations of a rigorous, analytical, consumer-sided rebound framework that is approachable for both energy analysts and economists. In this paper (Part II), we develop energy, expenditure, and consumption planes, a novel, mutually consistent, and numerically precise way to visualize and illustrate rebound. Further, we operationalize the macro factor () for macroeconomic rebound. Using the framework and rebound planes, we calculate and show …

Spreading Of Effluent Discharges From Two Adjacent Outfalls On A Sloping Seabed In Spring-Neap Tidal Waters, Anton Purnama, Ahmed Al-Kasbi, Easwaran Balakrishnan

Sultan Qaboos University Journal For Science

Coastal industrial plants dispose of their wastewater effluents into shallow coastal waters through sea outfalls. When two or more outfalls along a coastline are discharging, the long-term impacts are interdependent. Analytical solutions of two-dimensional advection-diffusion equations with a two-point source in a spring-neap oscillating tidal current on a sloping seabed are presented to study the far-field merging and interaction of two discharged effluent plumes in coastal waters. The elongated plumes are spreading towards the shoreline, and thus, asymptotic approximation is made to the analytical solution to assess the long-term build-up of effluent concentration at the shoreline. To show case the …

Effect Of Rotation On Plane Wave Propagation In A Magneto-Thermo Elastic Solid, G Rajkumar, K Somaiah, Srinivas Remidi Jul 2025

Effect Of Rotation On Plane Wave Propagation In A Magneto-Thermo Elastic Solid, G Rajkumar, K Somaiah, Srinivas Remidi

Sultan Qaboos University Journal For Science

The present article deals with the effect of angular rotation on the propagation of plane harmonic waves in a homogeneous, isotropic magneto-thermo elastic medium. The governing equations of a generalized magneto-thermo elastic solid are formulated and solved with the method of plane harmonic solution. Three types of waves, namely, plane longitudinal, magneto, and magneto-thermal waves, are significantly affected by the angular rotation of the solid. It is very interesting to observe that the classical result is obtained as angular rotation vanishes. For computational purposes, the available lithium niobate (LiNbO3) material was treated as the model of thermo-magneto elastic medium. The …
