Puf-Based Digital Money With Propagation-Of-Provenance And Offline Transfers Between Two Parties, Benjamin Bean, Cyrus Minwalla, Eirini Eleni Tsiropoulou, Jim Plusquellic
Puf-Based Digital Money With Propagation-Of-Provenance And Offline Transfers Between Two Parties, Benjamin Bean, Cyrus Minwalla, Eirini Eleni Tsiropoulou, Jim Plusquellic
Electrical and Computer Engineering ETDs
Building on prior concepts of electronic money (eCash), we introduce a digital currency where a physical unclonable function (PUF) engenders devices with the twin properties of being verifiably enrolled as a member of a legitimate set of eCash devices and possessing of a hardware-based root-of-trust. A hardware-obfuscated secure enclave (HOSE) is proposed as a means of enabling a PUF-based propagation-of-provenance (POP) mechanism, which allows eCash tokens (eCt) to be securely signed and validated by recipients without incurring any third party dependencies at transfer time. The POP scheme establishes a chain of custody starting with token creation, extending through multiple bilateral …
Testing For Dice Control At Craps, Stewart N. Ethier
Testing For Dice Control At Craps, Stewart N. Ethier
UNLV Gaming Research & Review Journal
Dice control involves “setting” the dice and then throwing them carefully, in the hope of influencing the outcomes and gaining an advantage at craps. How does one test for this ability? To specify the alternative hypothesis, we need a statistical model of dice control. Two have been suggested in the gambling literature, namely the Smith–Scott model and the Wong–Shackleford model. Both models are parameterized by θ ∈ [0, 1], which measures the shooter’s level of control. We propose and compare four test statistics: (a) the sample proportion of 7s; (b) the sample proportion of pass-line wins; (c) the sample mean …
Modeling Network Growth Via Generalized Isospectral Reductions, David Thomas Litster
Modeling Network Growth Via Generalized Isospectral Reductions, David Thomas Litster
Theses and Dissertations
Many real-world networks also exhibit a variety of symmetries. In this thesis we study equitable partitions and isospectral reductions, both of which are generalizations of symmetries. We formalize the relationship between these two types of generalized symmetry through the study of invariant subspaces. We then use recent results about the presence of equitable partitions in real-world networks to develop a network growth model that introduces similar structures, thereby introducing symmetries similar to those in real world networks.
Intrinsic Stability Of Controlled Systems Via Gershgorin-Type Estimates, David Friedbaum
Intrinsic Stability Of Controlled Systems Via Gershgorin-Type Estimates, David Friedbaum
Theses and Dissertations
Time delays are an inherent feature of real-world dynamical systems, arising whenever information, matter, or energy requires non-negligible time to propagate. Even small delays can destabilize systems that are otherwise well behaved, yet most standard control designs--such as PID or LQR--do not explicitly account for them and may fail when delays are present. This thesis investigates the stability of controlled dynamical systems subject to arbitrary time delays and develops new tools to determine when such systems remain stable. Our approach builds on the notion of intrinsic stability, a strong form of global stability introduced by Webb and Bunimovich, which guaranties …
Game-Theoretically Optimal Strategies In Baseball, William Michael Melville
Game-Theoretically Optimal Strategies In Baseball, William Michael Melville
Theses and Dissertations
Baseball players and their managers make numerous decisions that can have a significant effect on the result of the game. The effectiveness of their decision-making strategies depend on the strategies played by their opponents. For example, throwing a first-pitch fastball down the middle is a good strategy against a hitter who always takes the first pitch, but it is a risky strategy against a hitter who likes to swing at the first pitch and who is good at hitting fastballs. Additionally, any payoff a player receives from playing a strategy comes at the expense of their opponent. A batter cannot …
Play-Based Assessment Of The Cardinal Principle, Allyssa Sonnefeld Leavitt
Play-Based Assessment Of The Cardinal Principle, Allyssa Sonnefeld Leavitt
Theses and Dissertations
Gelman and Gallistel (1986) determined five counting principles that are essential for successful counting, including the cardinal principle where children understand that the last number counted represents the quantity of a set of objects. The traditional How many? task and the Give-n task are the most common tasks that have been used to assess whether children understand the cardinal principle. However, many researchers claim that these tasks either overestimate or underestimate children's understanding of the cardinal principle. Some researchers (Baroody & Pellegrino, 2023) suggest that embedding the traditional How many? task in a game may improve its validity. In this …

The Mechanics And Consequences Of The Löwenheim-Skolem And Compactness Theorems, Adam Murphy
The Mechanics And Consequences Of The Löwenheim-Skolem And Compactness Theorems, Adam Murphy
Honors Program Theses and Projects
The compactness theorem for first-order logic says that for a set of first-order sen-tences to be satisfiable, it’s enough for every finite subset to be satisfiable. We’ll see how the compactness theorem arises from two methods of model construction: first by ultraproducts, and second by Henkin’s method of constructing models from constant symbols. We’ll explore several representative applications of compactness, such as how it can be used to demonstrate that a property is not expressible, establishing limitations on first-order expressibility. The Löwenheim-Skolem theorem says that if an infinite set Γ of first-order sentences has an infinite model, then for all …

Analyzing Intellectual Alternatives To Student Academic Output ``A Specialized Study Of Academic Design Ideas And Alternatives'', Riyam Rajab Fanjan, Armin Sarkis Khosrof
Journal of King Abdulaziz University: Engineering Sciences
The design idea is the foundation on which the architectural design process. It is the basis for creating a distinguished architectural product that reflects the designer's thoughts, orientations, and way of thinking, whether within the black box or the glass box. Generating and selecting alternatives is one of the most important stages, followed by translating the alternative formally and functionally according to the design methodology followed by the designer and according to the design specifications represented by the type of project and its contextual constraints. In the context of architectural work, the research focuses on defining the design idea, the …
Perceptions Of Inclusion In Disability Communication With Plithogenic Fuzzy Soft Sets, Sonia Guerra Iglesias, Andrea Eugenia Pacheco Lemus, Vallardo Villegas-Ricauter, Lorena Del Carmen Bodero Arizaga, Luis Enrique Silva Adriano
Perceptions Of Inclusion In Disability Communication With Plithogenic Fuzzy Soft Sets, Sonia Guerra Iglesias, Andrea Eugenia Pacheco Lemus, Vallardo Villegas-Ricauter, Lorena Del Carmen Bodero Arizaga, Luis Enrique Silva Adriano
Neutrosophic Sets and Systems
This article explores how scientific communication with disability can foster social inclusion through an awareness of the challenge of conveying ambiguous perceptions across fields. This is a timely topic because inclusive communication facilitates equity and subsequent participation in academic and socio-cultural settings by persons with disabilities; however, the existing body of literature does not take an approach that represents an intrinsic indeterminacy of human perceptions. Absent this intrinsic human quality, research results oversimplify abilities and failures to include persons with disabilities. My approach fulfills this gap by using plitogenic fuzzy soft sets, which is a more generalized mathematical construct to …
Study Of Victimization And Perception Of Insecurity In Ecuador: Application Of Hybrid Models With Logistic Regression, Machine Learning, And Neutrosophy, Lorenzo Cevallos-Torres, Mauro M. F. Mediano
Study Of Victimization And Perception Of Insecurity In Ecuador: Application Of Hybrid Models With Logistic Regression, Machine Learning, And Neutrosophy, Lorenzo Cevallos-Torres, Mauro M. F. Mediano
Neutrosophic Sets and Systems
Given the victim's rising profile in contemporary victimology and criminology, this study examines victimization and the impact of perceived insecurity, paying particular attention to the situation in Ecuador, where reports of crime and violence in urban areas are on the rise. The overarching goal is to create a reliable model for victimization risk assessment that may also serve as an analytical tool for public policymaking and preventative efforts. One step is to build a classic logistic regression model that takes into account variables like age, sex, education level, occupational category, and level of physical activity. The goal is to understand …
Multi-Criteria Decision-Making For Bid Evaluation And Selection In Water Resource Management Projects, Abdulaziz Alkabaa, Salah Omar Ammari, Abdul Z. Hameed
Multi-Criteria Decision-Making For Bid Evaluation And Selection In Water Resource Management Projects, Abdulaziz Alkabaa, Salah Omar Ammari, Abdul Z. Hameed
Journal of King Abdulaziz University: Engineering Sciences
We propose an enhanced multi-criteria decision-making (MCDM) framework using the Analytic Hierarchy Process (AHP) tailored for bid evaluation in water resource management projects. This approach addresses the persistent challenges of transparency, inconsistency, and technical-financial weighting observed in competitive bidding systems. By incorporating structured criteria across qualitative and quantitative dimensions, our model offers a more systematic, equitable, and operationally robust alternative to traditional evaluation practices. Case study applications demonstrate the framework's ability to yield clear differentiation among bids, improve decision traceability, and support procurement efficiency. These findings offer practical implications for policymakers and project stakeholders seeking to modernize bidding practices within …
Design And Optimization Of A Geothermal Thermoelectric Generator System (Gteg) In Saudi Arabia, Hassan Fagehi
Design And Optimization Of A Geothermal Thermoelectric Generator System (Gteg) In Saudi Arabia, Hassan Fagehi
Journal of King Abdulaziz University: Engineering Sciences
The demand for renewable energy is growing rapidly, driven by climate change and the need for sustainable solutions. This study focuses on designing and optimizing a geothermal thermoelectric generator (GTEG) system in Saudi Arabia, leveraging the country's geothermal potential. The optimization process investigated key parameters such as substrate materials, thermoelectric leg length, and dimensionless thermal and electrical conductance. The results reveal that using AlN as a substrate material, combined with a reduced leg length of 0.1 mm, significantly enhances power output, achieving 8.5 W per module. Dimensionless analysis further identified optimal dimensionless thermal conductance (Nk = 0.291) and dimensionless …
Windkessel Parameter Estimation For Cardiovascular Feature Identification In Photoplethysmography Data, Calvin Boyce
Windkessel Parameter Estimation For Cardiovascular Feature Identification In Photoplethysmography Data, Calvin Boyce
Undergraduate Honors Theses
Features of cardiovascular health such as blood pressure, cardiac output, arterial compliance, and blood viscosity are important in evaluating heart health and disease risk, but are currently largely measured invasively and therefore only in critical settings. Here we explore the potential for Windkessel models to extract cardiovascular features from photoplethysmography (PPG) data in an attempt to evaluate heart health non-invasively. We show the capacity of a constrained Newton's method optimization scheme to estimate parameters and explore the tractability of the resulting parameters. While Newton's method is able to produce parameters that closely approximate PPG data, we found that using a …
From Drawing To Architecture: Michelangelo’S (Anti)Architectural Methodology, Yida Li
From Drawing To Architecture: Michelangelo’S (Anti)Architectural Methodology, Yida Li
The Crown: Syracuse Honors Research Journal
This paper investigates Michelangelo Buonarroti’s unique approach to architecture through the lens of his drawing practice, arguing that his architectural methodology evolved as an extension—and at times a deliberate rejection—of Renaissance architectural conventions. Beginning from his assertion that “architecture is not my profession,” the study situates Michelangelo’s creative identity within his grounding in disegno, the Renaissance concept that framed drawing as an intellectual act of conception rather than mere representation. Through comparative analysis with Leonardo da Vinci, the research traces how Michelangelo adapted the iterative, investigative qualities of draw-ing into a sculptural and spatial process that defied the rational, arithmetic-based …
Ubqln2 Puncta Formation Dependency On Expression, Domain Structure, And Heat Stress, Mallory Brown
Ubqln2 Puncta Formation Dependency On Expression, Domain Structure, And Heat Stress, Mallory Brown
The Crown: Syracuse Honors Research Journal
Ubiquilin 2 (UBQLN2) is a protein that recognizes ubiquitinated substrates and transports them to degradation machinery such as the proteasome. This pathway is crucial for protein quality control and disruptions in it may lead to neurodegenerative diseases such as Amyotrophic Lateral Sclerosis (ALS). UBQLN2 can coalesce to form puncta within the cell. Puncta are still liquid droplets but are separate from the dilute surrounding. It has been shown in vitro that certain domains of the UBQLN2 protein are crucial for its ability to form droplets. However, the influence of these droptlets within cellular UBQLN2 is less understood. The following research …
Rab32c Mediates Osmoregulation And Calcium Homeoastasis In Dictyostelium Discoideum, Ashley Esparza
Rab32c Mediates Osmoregulation And Calcium Homeoastasis In Dictyostelium Discoideum, Ashley Esparza
Theses and Dissertations
Vesicular trafficking is a fundamental process essential to cell viability and dictates roles in both cellular and tissue function in multicellular organisms. To further understand various vesicular trafficking processes, our lab focuses on the moderators of these processes, Rab GTPases, using the model organism Dictyostelium discoideum. This dissertation focuses explicitly on the uncharacterized protein Rab32C, a homolog of human Rab32. While several Rab family members have been well defined, the functionality of Rab32C remains poorly understood. This project investigated both the subcellular localization and functional role of Rab32C with biochemical, imaging, and molecular assays. Results from this study provide evidence …
Compositional Verification In Tla+, John Nguyen
Compositional Verification In Tla+, John Nguyen
The Crown: Syracuse Honors Research Journal
Formal verification is a subfield of computer science concerned with verifying the correctness of systems using mathematical techniques. It is easy to see from a cursory view that a pro-gram or protocol “does something,” but it is more difficult to see if it “does what you want it to do.” Formal verification allows developers to create a specification of a system that can be automatically verified as satisfying desired properties – formulating “what you want it to do” and proving it. One effective approach of formal verification is inductive invariant inference. An inductive invariant for a property P in a …

Gpu-Accelerated Effective Hamiltonian Calculator, Abhishek Chakraborty, Taylor L. Patti, Brucek Khailany, Andrew N. Jordan, Anima Anandkumar
Mathematics, Physics, and Computer Science Faculty Articles and Research
Effective Hamiltonian calculations for large quantum systems can be both analytically intractable and numerically expensive using standard techniques. In this manuscript, we present numerical techniques inspired by Nonperturbative Analytical Diagonalization (NPAD) and the Magnus expansion for the efficient calculation of effective Hamiltonians. While these tools are appropriate for a wide array of applications, we here demonstrate their utility for models that can be realized in circuit-QED settings. Our numerical techniques are available as an opensource Python package, qCHeff, which is available on GitHub (https://github.com/ NVlabs/qCHeff) and PyPI (https://pypi.org/ project/qcheff/). We use the CuPy library for GPU-acceleration …

Mathematics, Physics, and Computer Science Faculty Articles and Research
In Gil-Férez et al. (2025), we presented a proof of Postulate 4 using purely Euclidean techniques, against which Blåsjö (2025) raised several objections. In this note, we offer linguistic, textual, historical, and mathematical evidence that demonstrate that all these objections are baseless.
Artificial Intelligence For Smes In The Dominican Republic: A Strategic Neutrosophic Pest-Swot Analysis To Navigate Uncertainty, Karina Pérez Teruel
Artificial Intelligence For Smes In The Dominican Republic: A Strategic Neutrosophic Pest-Swot Analysis To Navigate Uncertainty, Karina Pérez Teruel
Neutrosophic Sets and Systems
This study examines the adoption of Artificial Intelligence (AI) in Dominican Republic SMEs through a PESTLE-neutrosophic analysis. PESTLE stands for Political, Economic, Social, Technological, Legal and Environmental factors. Neutrosophic is the Philosophy of Indeterminacy. Therefore, we focus on the factors relative to AI adoption in the Dominican Republic—specifiers to the benefits and drawbacks, as well as, the unknowns of operating with AI—with the intention of illuminating attention. The findings support a phased approach for SMEs to view indeterminacy as an opportunity for competitive advantage through improved operational efficiencies, enhanced customer experience, and more informed decision-making. Ultimately, the results position AI …
Shallow Groundwater Extraction Strategies In The Las Vegas Valley, Nevada, Teryl Stacey
Shallow Groundwater Extraction Strategies In The Las Vegas Valley, Nevada, Teryl Stacey
UNLV Theses, Dissertations, Professional Papers, and Capstones
The Las Vegas Valley faces severe water scarcity due to Nevada’s limited Colorado River allocation and an arid climate. Population growth and prolonged drought have intensified these constraints, necessitating alternative resource strategies. This project evaluated a strategy to make use of brackish, shallow groundwater (from the top 30 feet below ground surface) located in the central and east-central parts of the valley. Its objective was to extract lower quality shallow groundwater for use as an alternative to fresh water currently being used for some applications that require little to no treatment. Dust suppression is among the most promising of such …
Mapping Climatic And Environmental Determinants Of Parasitic Helminth Prevalence In Southeast Asia, Angelica Avisado
Mapping Climatic And Environmental Determinants Of Parasitic Helminth Prevalence In Southeast Asia, Angelica Avisado
UNLV Theses, Dissertations, Professional Papers, and Capstones
Climate change is reshaping environmental conditions across Southeast Asia (SEA) through rising temperatures, altered precipitation patterns, and increased droughts. These changes alter transmission dynamics of neglected tropical diseases (NTDs) by shifting spatial distribution, increasing larval development rates, faster pathogen growth development, and increasing transmission rates. NTDs are a group of preventable and treatable infections that disproportionately affect more than 1 billion people globally, specifically in tropical and subtropical regions. A subgroup of NTDs, parasitic helminth infections (PHIs) - particularly schistosomiasis, soil-transmitted helminths, and lymphatic filariasis remains a public health concern in the Southeast Asian region. PHIs and their ecological responses …
Automated Spectrum Analysis And Radionuclide Identification For Robot-Based Gamma Probes, Kennedy Ochieng Mengoh Alila
Automated Spectrum Analysis And Radionuclide Identification For Robot-Based Gamma Probes, Kennedy Ochieng Mengoh Alila
UNLV Theses, Dissertations, Professional Papers, and Capstones
Gamma spectroscopy is a technique used for the detection and identification of nuclear materials. Gamma-ray emission by radio nuclides is detected using scintillation detectors or semiconductor detectors such as NaI and CZT. Robot-based gamma probes enable radiation measurements in large areas and hard-to-reach cluttered hazardous environments, which significantly reduces radiation risks to personnel. The robotic probes require automated on-board gamma spectrum analysis and capabilities with platforms (unmanned aerial vehicles and unmanned ground vehicle systems) which use Robot Operating System (ROS). The aim of this thesis was to develop a method of an automated spectral analysis and isotope identification for robot-based …
Examining The Complementary Nature Of Working Memory And Dual Coding Theory, Elizabeth Hofschulte Collins
Examining The Complementary Nature Of Working Memory And Dual Coding Theory, Elizabeth Hofschulte Collins
UNLV Theses, Dissertations, Professional Papers, and Capstones
The working memory system is responsible for maintaining, manipulating, and transferring information into long-term memory, yet it operates under strict capacity limitations. Dual coding theory proposes that information can be encoded both verbally and visually, allowing learners to distribute cognitive load across complementary representational systems. Leveraging dual coding may therefore enhance recall, particularly for noun-based stimuli, though there is little to no research exploring this possibility. In the present study, 529 adults completed a forward digit span task and pre-test and post-test free recall tasks involving concrete, abstract, and mixed nouns. Participants were assigned to one of four instruction groups …
Applying Instrumental Neutron Activation Analysis (Inaa) To Characterize Trace Elements In Water Samples Around Lake Mead, Danesha Hunter
Applying Instrumental Neutron Activation Analysis (Inaa) To Characterize Trace Elements In Water Samples Around Lake Mead, Danesha Hunter
UNLV Theses, Dissertations, Professional Papers, and Capstones
Lake Mead, the largest reservoir in the United States is located on the boarder of Nevada and Arizona. Despite reaching historically low water levels, it continues to supply water and energy to millions of Americans in the southwest. It is well known that the United States suffers from negative implications from nationwide drought. The ongoing megadrought affecting the Colorado River Basin and its tributaries undergoes the urgent need to assess the future water quality of Lake Mead as it continues to shrink. With water levels depleting at an alarming rate, water quality is significantly impacted, indicating that heavy metal accumulation …
Post-Probationary Principals’ Perceptions Of Professional Development, Matthew Jackson
Post-Probationary Principals’ Perceptions Of Professional Development, Matthew Jackson
UNLV Theses, Dissertations, Professional Papers, and Capstones
This qualitative phenomenological study explored post-probationary principals’ perceptions of professional development, examining the relevance, adequacy, and impact of support provided after 4 years of their leadership. Although research and policy have emphasized the development of new principals, professional learning opportunities for those beyond probationary status remain inconsistent, generic, and misaligned with individual and contextual needs. Guided by adult learning theory, this study sought to understand how post-probationary principals evaluate current professional development, describe their desired opportunities, and determine their ongoing needs. Data were collected through semi-structured interviews with principals from multiple districts and analyzed using coding, memo writing, and mind …
Computational Study Of Cavitation In An Inducer Pump, Jaylen Leonard
Computational Study Of Cavitation In An Inducer Pump, Jaylen Leonard
UNLV Theses, Dissertations, Professional Papers, and Capstones
Cavitation is ubiquitous in liquid-handling turbomachines. Cavitation bubbles form when the local pressure drops below a fluid’s vapor pressure, and their subsequent collapse causes implosions that generate shockwaves and microjets. These effects lead to fluid instability and structural damage to the blades and casing in turbomachines. This thesis investigates this cavitation phenomenon in turbomachines using Computational Fluid Dynamics (CFD). The cavitation model built in ANSYS Fluent® is first validated in a venturi tube model and then applied to an inducer pump. The geometry of the pump is derived from the Space Shuttle Main Engine (SSME) Low Pressure Oxidizer Pump (LPOP) …
Geometric And Proximity Based Substrate Targeting By Cullin-Ring Ligases, Jerry Li
Geometric And Proximity Based Substrate Targeting By Cullin-Ring Ligases, Jerry Li
UNLV Theses, Dissertations, Professional Papers, and Capstones
Homeostasis, the process of maintaining stable biochemical and biophysical conditions, is a fundamental facet of cellular viability. Biochemical homeostasis is critical to support the biological functions that sustain living organisms. Protein ubiquitylation is one of the primary cellular pathways that regulate protein homeostasis and turnover. Ubiquitylation is initiated through the conjugation of a small globular protein known as ubiquitin, onto a given substrate. There exists a myriad of cellular fates that ubiquitylated proteins may undergo, but the most widely studied pathway is protein degradation, whereby a ubiquitylated protein substrate is shunted to a large macromolecular protease known as the proteasome, …
