An Authentic Key To Universality: The National Sound Of Tajčević And The International Sound Of Milojević In Serbian Piano Music, Nikola Šćepović

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis argues that the authenticity of the works of Marko Tajčević and Miloje Milojević arises from their deep artistic response to the cultural and historical environment in which they lived and created, while their universality lies in their ability to articulate this authentic language within established artistic forms that resonate with a broader international musical community. It situates these works within the broader cultural context of Serbian music between the two World Wars, a period marked by the negotiation between national identity and European artistic integration.1

It also explores the two formative directions of Serbian piano music, the music …

Examining The Effects Of Tailored Ergonomic Interventions On Reducing Musculoskeletal Disorders For Taxi Drivers, Amal Youssouf

UNLV Theses, Dissertations, Professional Papers, and Capstones

Taxi drivers are frequently exposed to prolonged sitting, whole-body vibration, limited rest opportunities, and psychosocial stressors, placing them at increased risk for musculoskeletal disorders (MSDs). This can be mitigated with the use of ergonomics, which changes one's environment to match an individual's needs within the context and demands of the job. Although ergonomics is a recognized area of occupational therapy (OT) practice, current research is limited to office-based or computer-related settings, leaving a gap in OT-led ergonomic interventions tailored for professional drivers. This capstone project aimed to determine whether OT-based ergonomic strategies, along with an ergonomic checklist as a guideline …

From Natural Language To Cryptographic Protocol Specifications: Evaluating Llms For Cpsa Generation, Martin Duclos

Theses and Dissertations

Formal verification can prove the security properties of cryptographic protocols, but translating natural language specifications into formal models requires specialized expertise, limiting the broader adoption of formal verification methods. This dissertation investigates whether large language models (LLMs) can lower this barrier by automatically generating Cryptographic Protocol Shapes Analyzer (CPSA) models from natural language protocol specifications. We evaluate three complementary strategies for improving LLM-based CPSA code generation through systematic experimentation across 104 protocols and 15 language models. First, we analyze prompt engineering and find that moderate structured guidance yields the most accurate outputs, while excessive prompt complexity degrades performance. Second, we …

Intersection Of Food Insecurity And Housing Among Veterans And Disabled Adults, Julie Anne Stepp

Theses and Dissertations

This study examines how housing tenure is associated with food insecurity (FI) among veterans and adults with disabilities, utilizing the housing-food insecurity nexus framework. Previous research documents elevated FI among veterans and individuals with disabilities, yet few studies assess housing tenure as a mechanism connecting these statuses to food hardship. Using data from the 2024 National Health Interview Survey Adult Sample (n=32,629), logistic regression models estimate the independent and interactive effects of renting, veteran status, and disability status on FI. Results suggest renters have significantly higher odds of FI than homeowners, even after adjusting for poverty status, SNAP participation, and …

Reconciliation: An Auditory Exploration Of Redemptive Suffering, Emily Eid

MFA in Visual Art

Reconciliation examines the intersection between chronic pain, Catholic theology, and contemporary sound art through the lens of radical honesty. It documents a dramatic aesthetic and spiritual pivot in my art practice, moving from grotesque, abject portrayals of agony to a hopeful representation of redemptive suffering. I share how the project evolved from an installation of anthropomorphic furniture to a sculptural work using my bed, to an audio piece presented in a semi-private “confessional booth,” all while challenging the misconceptions surrounding chronic pain and disability. Utilizing the theories of Roland Barthes, I break down the semiological and authorial aspects of the …

Within These Walls, Nicholas J. Roberts

LSU Master's Theses

I was raised to understand home through labor. In the working-class household I grew up in, in rural Southeastern Pennsylvania, value was earned through work, identity took shape through trade, and rest was often an afterthought. That framework was not chosen. It was inherited. And it has not been easy to see it clearly from the inside.

The Exhibition, Within These Walls, examines that inheritance through printmaking and sculpture, using the material and spatial language of domestic construction as both subject and method. Through fragile paper structures that resemble wood but cannot hold weight, a staircase that cannot be climbed, …

Classification Of Hif Detection In Nev Profile Using Wavelet Transform And Convolution Neural Network, Abdul Hafiz Kassim, Mohd Abdul Talib Mat Yusoh, Aster Smith Valentinie Wilson Nottelmarc, Ahmad Farid Abidin, Sim Sy Yi, Daw Saleh Sasi Mohammed

Turkish Journal of Electrical Engineering and Computer Sciences

High impedance faults (HIFs) present a critical challenge in power systems due to their subtle signal characteristics, which often remain undetected by conventional protection methods. These faults typically do not produce significant phase disturbances, making reliable detection difficult. However, analysis of the neutral-to-earth voltage (NEV) profile under fault conditions provides a promising alternative for fault identification. Existing approaches for detecting and classifying HIFs using NEV signals remain limited and may result in inaccurate maintenance decisions. This paper proposes a fault classification framework for multiple fault types, including HIF, three-phase fault, three-phase fault to ground, double line, double line to ground, …

Complex-Valued Convolutional Neural Network With Time-Frequency Representation For Electrocardiogram-Based Arrhythmia Detection, Kajeeth Kumar Gurusamy, Muthurajkumar Sannasy

Turkish Journal of Electrical Engineering and Computer Sciences

This research proposes an end-to-end procedure for arrhythmia detection based on electrocardiogram (ECG) signals using complex-valued convolutional neural network (CVCNN) incorporated with time-frequency representation. The proposed model leverages complex numbers to capture amplitude and phase information that enhances the ability of the model for detecting time-frequency variation in cardiac signals. First, signal preprocessing techniques---including normalization, wavelet denoising, and R-peak detection---are applied. Subsequently, the model extracts complex features from raw ECG data by employing the Hilbert transform to derive the analytic signal and the short-time Fourier transform (STFT) to generate a time–frequency representation. The proposed CVCNN framework effectively learns spatial-temporal features …
