Mesopotamian Journal of Big Data

Diabetes-related eye diseases are the leading cause of blindness amongst working-age individuals and represent a serious global health concern. Early detection is essential to prevent vision loss. However, current screening techniques face limitations in scalability and accessibility. A deep learning (DL) method for automatically classifying retinal images into four groups—diabetic retinopathy, normal, glaucoma and cataract—is presented in this work. We developed and assessed a convolutional neural network (CNN) model using transfer learning (TL) with EfficientNetB3 as the foundational architecture, utilising a diverse dataset of over 4,000 retinal images collected from various sources. Our model achieved an overall accuracy of 91.3%, …

Cooperation And Conflict: Oswald Veblen And Abraham Flexner, Juan Carvajalino, Della Dumbaugh

Department of Math & Statistics Faculty Publications

In 1929, Caroline Bamberger Fuld and her brother, Louis Bamberger, sold their department stores, Bamberger & Co., at a particularly timely moment. They invested their sizeable fortune in a new academic initiative in America, an institute devoted to research that would go by the name of the Institute for Advanced Study. This paper introduces two colleagues, Abraham Flexner and Oswald Veblen, and explores the cooperation and conflict between them as they worked alongside one another to shape the Institute for Advanced Study and the School of Mathematics within it.

All-Inside Endoscopic Zone 1 Flexor Hallucis Longus Transfer: A Cadaveric Feasibility Study., Kevin D Martin, Yi Wei, Adam G F Smith, Franco Piscitani, Luke M Martin, Brian Steginsky, Brian Tscholl, Nathaniel A Bates

Surgery Articles

BACKGROUND: Endoscopic flexor hallucis longus (FHL) tendon transfer addresses chronic Achilles tendon ruptures. Traditional percutaneous plantar incisions gain FHL length but risk neurovascular injury. This study evaluated the feasibility of an all-inside endoscopic FHL zone 1 tenotomy and transfer technique, which avoids plantar incisions by using zone 1 of the FHL tendon. We hypothesized that this technique would (1) provide sufficient tendon length, (2) avoid neurovascular damage, and (3) securely anchor the FHL tendon without tunnel blowout.

METHODS: Ten cadaveric all-inside endoscopic zone 1 FHL tendon transfers were performed without fluoroscopic guidance. Specimens were independently assessed post hoc by 2 …

Mechanical Engineering Capstone Design Projects

The contents of this report contain the details of the 2025-2026 school year regarding team 14’s capstone project about building an Unmanned Underwater Vehicle (UUV) using sound detection. At the beginning of this project it was decided that the project goals would be updated. In previous years the students had to use sound to follow a path and drop a payload along that path in the pool. Now this has been changed so that the team now knows the path and drop location beforehand. This removes the need for sonar and sound detection. This makes the project easier and more …

Determining Effective Community Policing Programs Within Law Enforcement Agencies, Paul L. Alexander

Doctoral Dissertations and Projects

The purpose of this applied study was to identify effective community policing programs in law enforcement and among political leaders by designing a structural equation model that incorporates specific variables to address the issue. It employed a proposed conceptual model to illustrate the analysis process and a structural equation conceptual model (SECM) to perform the analysis using specific variables. The reason this research was necessary was to determine whether it is possible to overcome the lack of a universally accepted definition of community policing. The data collection methods in this study included interviews, document reviews, surveys, and analyses of federal …

Evaluating Inner-Tainment With A Ghetto Perspective For Positive Thought Adjustment In Ghetto Communities, Shontae L. Graham

Doctoral Dissertations and Projects

Environmental challenges and disadvantages impact cognitive scripts and develop persistent frustration. Frustration is both mental and physical and can be negative or positive. It evokes emotion, which is prompted by memory and its associated level of importance. The integration of emotion, memory, and imagination can set the stage and create an act to transition negative frustration and align past experiences with new perspectives. This study used a qualitative Interpretive Phenomenological Analysis approach to investigate the use of self-scripted enactment as a self-help technique for positive thought adjustment. The technique is called Inner-tainment and was used to determine if there were …

Study Of Complex Biological Systems Through Ai-Empowered Metabolomic Analysis And Modeling, Runyu Zhao

McKelvey School of Engineering Graduate Student Theses & Dissertations

This dissertation establishes an integrated framework that leverages artificial intelligence (AI) and advanced metabolomics to overcome the "complexity bottleneck" in microbial engineering, specifically addressing the global crises of plastic waste and carbon emissions. By framing the research within the complex biosystems for effective bioproduction and bioremediation, this work develops novel strategies to engineer and analyze biological systems for a circular bioeconomy. In the "Build" phase (Chapter 2), the study addresses the instability of synthetic microbial consortia. By utilizing calcium-alginate hydrogel compartmentalization, the research successfully decouples the growth of the phototroph Synechococcus elongatus from its heterotrophic partners (P. putida and Y. …

Racial stress is conceptualized as a multidimensional construct that includes racial trauma, racial violence exposure through social media, and racial discrimination distress. This study addresses gaps in the literature by examining the prevalence of mental health outcomes, emotional responses to these experiences, and the role of racial stressors over time. Using three waves of data, this study assesses the proportion of participants meeting clinical cutoff scores for depression and anxiety using the Multiple Affect …

Building Human-Aware Ai: Learning From And Assisting Human Decision-Makers, Saumik Narayanan

McKelvey School of Engineering Graduate Student Theses & Dissertations

As artificial intelligence systems become more capable, they are increasingly used not only as standalone problem-solvers, but as systems that learn from and interact with humans. In these settings, success depends not only on the strength of the model in isolation, but also on how well it fits the humans it is trained on or deployed alongside. This dissertation argues that human heterogeneity is a central ingredient in the design of effective human-aware machine learning systems. Rather than treating differences between people as noise to be averaged away, I show that variation in human expertise and preferences can provide useful …
