Cover Song Identification - A Novel Stem-Based Approach To Improve Song-To-Song Similarity Measurements, Lavonnia Newman, Dhyan Shah, Chandler Vaughn, Faizan Javed

SMU Data Science Review

Music is incorporated into our daily lives whether intentional or unintentional. It evokes responses and behavior so much so there is an entire study dedicated to the psychology of music. Music creates the mood for dancing, exercising, creative thought or even relaxation. It is a powerful tool that can be used in various venues and through advertisements to influence and guide human reactions. Music is also often "borrowed" in the industry today. The practices of sampling and remixing music in the digital age have made cover song identification an active area of research. While most of this research is focused …

CORD-19 is a corpus of published peer reviewed and pre-peer reviewed articles related to the coronavirus that causes COVID-19. Using machine learning techniques, such as Non-negative Matrix Factorization for Natural Language Processing and a Bayesian classifier, we developed a novel framework and system that automatically extracts sparse and meaningful …

An Examination Of The Rdoc Negative Valence Systems Domain Constructs And Self-Report Unit Of Analysis, Anni Hasratian

Psychology Theses and Dissertations

In response to shortcomings with the current categorical diagnostic classification system for mental health disorders, such as reliance on fixed disorder definitions and heterogeneity within disorders, the National Institute of Mental Health proposed the Research Domain Criteria (RDoC) initiative to move towards a dimensional approach using translational research. The current study examined associations between widely used measures of behaviors, cognitions and mental health symptoms and how they overlap in the Negative Valence Systems (NVS) domain. Specifically, we examined how self-reports unit of analysis reflect the acute threat, potential threat, sustained threat, frustrative non-reward, and loss constructs proposed by RDoC.

Wireless Wearable System For The Assessment Of Gait, Abdallah Jabr

Mechanical Engineering Research Theses and Dissertations

This work investigates the development and use of a wireless wearable system for the assessment of gait. The system proposed consists of a sensor module that is attached to the foot. The sensor proposed is an inertial measurement unit, often abbreviated as IMU - a 9-axis System in Package (SiP) including a 3-axis accelerometer, a 3-axis gyroscope, and a 3-axis magnetometer, as well as a fusion engine for signal processing. While the focus of this work is on evaluating gait metrics, the performance of the proposed IMU in evaluating orientation is quantified. In doing this work, we try to address …

Homogenization Of Composite And Cellular Materials Incorporating Microstructure And Surface Energy Effects, Ahmad Gad

Mechanical Engineering Research Theses and Dissertations

In the last few decades, the popularity of composite and cellular materials has rapidly increased through their widespread applications in multiple engineering fields including aerospace, automotive, civil and biomedical. However, to a large extent, the success of their practical applications depends on our ability to predict their mechanical behavior by using high-fidelity mechanics models.

Micromechanical modeling of composite and cellular materials is a challenging task due to the heterogeneous nature of such materials and the interactions among various constituent phases at the microscopic level, which result in non-homogeneous deformation, strain and stress fields. Therefore, it is necessary to develop simple …

Drug Free America: The Ethics And Politics Of Drugs In Contemporary American Literature, Kevin Pickard

English Theses and Dissertations

The utopian vision behind the so-called War on Drugs was that, as with other wars, we might sacrifice some amount of individual freedom in order to gain a larger freedom. In this case, the larger freedom was what Nancy Reagan called a “drug free America.” Thus, the War on Drugs era (from roughly 1970 to the present) aligns historically yet exists in tension with what scholars have called the neoliberal era, wherein individual freedom is paramount, and moral, political, and economic responsibility is left to the individual. This dissertation asks what the depictions of drug use in literature from this …

Cognition And Context-Aware Computing: Towards A Situation-Aware System With A Case Study In Aviation, Justin C. Wilson

Computer Science and Engineering Theses and Dissertations

In aviation, flight instructors seek to comprehend the intent and awareness of their students. With this awareness, derived from in-flight observation and post-flight examination, a human instructor can infer the internal contexts of their student aviators as they perform. It is this understanding that is fundamental for evaluating student development. Further, a well-understood construct for describing the state of knowledge about a dynamic environment is known as situational awareness (SA). Often pilot error is associated with SA [80], and it is fundamental to flight safety and mission execution. If these contexts can be automatically inferred, instructors and students can more …

A 2.56 Gbps Serial Wireline Transceiver That Supports An Auxiliary Channel And A Hybrid Line Driver To Compensate Large Channel Loss, Xiaoran Wang

Electrical Engineering Theses and Dissertations

Serial transceiver links are widely used for high-speed point-to-point communications. This dissertation describes two transceiver link designs for two different applications.

In serial wireline communications, security is an increasingly important factor to concern. Securing an information processing system at the application and system software layers is regarded as a necessary but incomplete defense against the cyber security threats. In this dissertation, an asynchronous serial transceiver that is capable of transmitting and receiving an auxiliary data stream concurrently with the primary data stream is described. The transceiver instantiates the auxiliary data stream by modulating the phase of the primary data without …

Rela/P65 Blocks Histone Deacetylase-3 Neurotoxicity And Protects Neurons Against Neuronal Death Induced By Polyq-Expanded Huntingtin And Ataxin-1 In A P65 Phospho S276 Dependent Manner, Yiyu Zhang

Biological Sciences Theses and Dissertations

Neurodegenerative diseases have a large negative impact to human society. Symptoms of neurodegenerative diseases includes memory loss, impaired recognition, motor dysfunction due to dysregulated neuronal loss in different brain regions. However, the neurobiological basis of these brain diseases is not fully understood and there are no cures or effective treatments. Polyglutamine (Poly-Q) disorders is a class of neurodegenerative diseases that are caused by polyglutamine expansion within the protein coding regions of specific genes. Huntington’s disease (HD), Spinal Cerebellar Ataxia Type 1 (SCA1) and Spinal Cerebellar Ataxia Type 3 (SCA3) are three common diseases among Poly-Q disorders. To better understand the …

Stare Decisis And The Identity-Over-Time Problem: A Comment On The Majority's Wrongness In Kisor V. Wilkie, Christian Talley

SMU Law Review Forum

In Kisor v. Wilkie, the Supreme Court recently confronted whether to overrule the doctrine under which courts defer to agencies’ interpretations of their own ambiguous regulations—so-called Auer or Seminole Rock deference. In its prior reexaminations of Seminole Rock, the Court had progressively restricted the doctrine’s scope, leading observers to wonder whether the Justices would scrap it for good. This question of administrative law ignited a corollary debate about stare decisis. Writing for the majority, Justice Kagan argued that stare decisis mandated the preservation of Seminole Rock. Yet as she appealed to stare decisis, her opinion further restricted …

Rolling In The Modern: The Mahler-Roller Productions Of The Vienna Court Opera House (Historical Essay And Syllabus), Gregory Eckhardt

Music Theses and Dissertations

This project takes the Mahler-Roller productions at the Vienna Court Opera House as a case study to examine the ways that contemporary artistic trends can influence operatic productions. By analyzing the sketches Roller created for their productions, I argue that Mahler and Roller expanded the Wagnerian Gesamtkunstwerk to both increase the production quality, the metaphorical content, and set a new standard for interpretive operatic productions.

This project is divided into two parts. Part I is a historical essay that provides context for the Mahler-Roller productions. I first outline the history of the Wagnerian Gesamtkunstwerk and discuss the ways that Wagner …

Determining How The Human T-Cell Leukemia Virus Type-1 (Htlv-1) Latency-Maintenance Factor P30ll Modulates Antioxidant- Signaling To Promote Oncogene Activation During Retroviral Carcinogenesis, Tetiana Bowley

Biological Sciences Theses and Dissertations

The Human T-cell Leukemia Virus Type-1 (HTLV-1) is a complex oncogenic deltaretrovirus that infects and transforms CD4+ T-lymphocytes and is the etiological agent of Adult T-cell Leukemia/Lymphoma (ATL). HTLV-1 latency-maintenance factor p30^II downregulates proviral gene expression at the transcriptional and posttranscriptional levels and aids in immune escape from the host immune surveillance. HTLV-1 p30^II competes with HTLV-1 transactivator Tax for binding to CBP/p300 coactivator; this competition determines if there is Tax-mediated transcription initiation or viral gene silencing induced by p30^II. Our research group has previously demonstrated that the HTLV-1 p30^II accessory protein induces the p53 …

Application Of Optimal Switching Using Adaptive Dynamic Programming In Power Electronics, Ataollah Gogani Khiabani

Mechanical Engineering Research Theses and Dissertations

In this dissertation, optimal switching in switched systems using adaptive dynamic programming (ADP) is presented. Two applications in power electronics, namely single-phase inverter control and permanent magnet synchronous motor (PMSM) control are studied using ADP. In both applications, the objective of the control problem is to design an optimal switching controller, which is also relatively robust to parameter uncertainties and disturbances in the system. An inverter is used to convert the direct current (DC) voltage to an alternating current (AC) voltage. The control scheme of the single-phase inverter uses a single function approximator, called critic, to evaluate the optimal cost …

Control And Locomotion Of Inertially And Magnetically Actuated Multi-Scale Robotic Systems, Ehab Al Khatib

Mechanical Engineering Research Theses and Dissertations

In this research, two actuation systems were introduced, inertial and magnetic actuation. In the inertial actuation, the robot used the transfer of momentum to navigate, and this momentum could be generated by spinning masses and wheels. Recent studies in our System Laboratory proved that a wide range of inertially actuated locomotion systems could be generated. This can be achieved by using a family tree approach, starting from a very simple system, and progressively evolving it to more complex ones. The motion diversity of these robots inspired us to extend their locomotion from a macro scale to millimeter and micro scales. …

Pluralism As A Social Practice: A Pragmatist Approach To Engaging Diversity In Public Life, Mary Leah Friedline

Religious Studies Theses and Dissertations

My dissertation lays a theoretical framework for rethinking the ways in which political and moral philosophers conceive pluralism and diversity in public life. I argue that many philosophers who write on the topic do not have a sophisticated understanding of religion, are not sufficiently attentive to historically produced power differentials, and/or do not adequately recognize the intersectional dimensions of diversity. Building on Jeffrey Stout’s notion of democracy as a social practice, and supplemented with Cornel West’s understanding of democratic faith, I use my more complex account of diversity to argue that pluralism is best approached as a social practice, instead …

Forgotten: A Study Of The Long-Term Economic Ramifications Suffered By Survivors Of Violence Against Females Sustained During State-Terror Such As Genocides, Natasha Holmark Andersen

Graduate Liberal Studies Theses and Dissertations

In an attempt to answer the question: What are the long-term economic ramifications of sexual violence against females in state terror such as genocide? This paper explores the thematic elements, conducive factors and the effects of the existence of sexual violence in state-terror genocides.

To do this, the paper first explores the elements of terrorism and apply them directly to state terror. The notion that states are immune from the blame of terrorism is acknowledged and debunked, furthering the association between terrorism and acts of state terror. Next, genocide is defined as the most atrocious act of state terror, and …

Heuristics For Sparsest Cut Approximations In Network Flow Applications, Fernando Vilas

Computer Science and Engineering Theses and Dissertations

The Maximum Concurrent Flow Problem (MCFP) is a polynomially bounded problem that has been used over the years in a variety of applications. Sometimes it is used to attempt to find the Sparsest Cut, an NP-hard problem, and other times to find communities in Social Network Analysis (SNA) in its hierarchical formulation, the HMCFP. Though it is polynomially bounded, the MCFP quickly grows in space utilization, rendering it useful on only small problems. When it was defined, only a few hundred nodes could be solved, where a few decades later, graphs of one to two thousand nodes can still be …

Nonlinear Photonics In Twisted And Nonlocal Structures, Austin Copeland

Mathematics Theses and Dissertations

We provide a theoretical framework for the observed confinement of light modes within a twisted coreless photonic crystal fiber. Asymptotic methods are applied through ray theory and field theory in both the linear and nonlinear regime. We find the modes have a radially symmetric chirp and the envelope will decay away from the axis of propagation. Secondly, we study the stability and singularity formation of unidirectional beams as described by the Schrodinger equation. We propose a novel extension to the modeling equation to include a fractional Laplacian in one spatial dimension and a standard second derivative in a second dimension. …

We then selected a subset of …

The Data Market: A Proposal To Control Data About You, David Shaw, Daniel W. Engels

SMU Data Science Review

The current legal and economic infrastructure facilitating data collection practices and data analysis has led to extreme over-collection of data and the overall loss of personal privacy. Data over-collection has led to a secondary market for consumer data that is invisible to the consumer and results in a person's data being distributed far beyond their knowledge or control. In this paper, we propose a Data Market framework and design for personal data management and privacy protection in which the individual controls and profits from the dissemination of their data. Our proposed Data Market uses a market-based approach utilizing blockchain distributed …
