Mechanical Engineering Undergraduate Honors Theses

This study utilized narrative reports from the National Aeronautics and Space Administration (NASA) Aviation Safety Reporting System (ASRS) database to examine the types of uncertainty present in near-miss instructional aviation incidents occurring within the United States between 2015 and 2025. The final dataset consisted of 86 reports, with each report containing a set of narrative accounts from both the student pilot and the flight instructor operating under Part 91 regulations. Each instructional event was classified using a combined framework incorporating uncertainty categorizations and the Human Factors Analysis and Classification System (HFACS). Results indicate that epistemological uncertainty was the most common …

Artificial Intelligence And Translation: Exploring Current Applications, Limitations And Future Potential Of Language Models Through Japanese-English Translation, Loklin Elias Nord

Undergraduate Theses, Capstones, and Recitals

This thesis highlights the recent improvements and capabilities of Large Language Models (LLMs), specifically their ability to produce translations between different languages. The continued up-scaling of model sizes has led to breakthroughs in the level of their observed intelligence, allowing them to produce translations that are similar in quality to highly skilled human translators. However, to facilitate the reasoning processes that LLMs now possess, their demand for computational power and the supporting hardware and resources has increased proportionally. Considering the impacts of this technology on the environment, energy resources, and its accessibility, my research explores the possibilities of smaller, highly …

Digital Maturity In The Administrative Prosecution In Egypt, Asmaa A. Hassan

Theses and Dissertations

The growing deployment of information and communication technologies in public service delivery, in general, and in the judiciary in particular, underscores the need for an assessment tool to evaluate digital maturity. Understanding digital maturity, a state in which an organization has completed digital development, helps diagnose the status quo, identify enablers, and address challenges, and consequently provide a roadmap for efficient improvements. This study aims to examine key factors affecting digital maturity within the Administrative Prosecution (AP) in Egypt, a pillar of the judicial authority and mandated to investigate financial and administrative violations committed by public servants. A mixed-methods approach …

From Planned To Lived: Street-Level Transformation And The Production Of Urban Space In New Cairo, Seba Abouyoussef

Theses and Dissertations

Egypt's new cities program has produced four generations of satellite developments, yet none have been systematically evaluated for how they perform once inhabited. Each is planned as a prototype — functionally zoned, automobile-oriented, image-driven — with little regard for the social, cultural, and behavioral dynamics that will shape it. This thesis examines the gap between the planned city and the lived city by tracing how three streets in New Cairo transformed over a fifteen-year period (2010–2025) through everyday use, stakeholder interaction, and pivotal trigger events.

The research follows a qualitative, multi-phase methodology — combining historical and physical mapping, behavioral observation, …

Ai Failures In The Eyes Of The Downstream Developer: A First Look At Concerns, Practices, And Challenges, Haoyu Gao, Mansooreh Zahedi, Wenxin Jiang, Hong Yi Lin, James C. Davis, Christoph Treude

Research Collection School Of Computing and Information Systems

With the advancement of AI models, more software systems are adopting AI as a component to facilitate automation. Pre-trained models (PTMs) have become a cornerstone of AI-based software, allowing for rapid integration and development with lower training cost. However, their adoption also introduces failure modes such as data leakage and biased outputs, that may require careful handling by downstream developers. While previous research has proposed taxonomies of these technical concerns and various mitigation strategies, how downstream developers address these issues during the development of general AI-based software when reusing PTMs remains unexplored. Understanding downstream developers’ perspectives is essential because they …

Light Optical Microscopy (LOM) overview images and high magnification images were obtained, and the interface was characterized by Scanning Electron Microscopy equipped with Energy Dispersive X-ray Spectroscopy (SEM-EDS). Moreover, nano-indentation hardness measurements were conducted. Results showed that porosity significantly affected the integrity of …

Nanoscale Water Confinement And Coordination-Driven Ion Transport In Eutectogel Electrolytes For Electrochemical Energy Storage Applications, Abdallah Akar

Theses and Dissertations

The rapid expansion of renewable energy systems, portable electronics, electric vehicles, and smart grid technologies has intensified the demand for advanced electrochemical energy storage devices capable of delivering high power density, long cycling life, operational safety, and environmental sustainability. Among these technologies, supercapacitors have attracted considerable attention because of their rapid charge-discharge capability, excellent cycling stability, and high-power performance. However, their relatively low energy density remains a critical limitation that restricts their broader practical application. Since the energy density of supercapacitors scales with the square of the operating voltage, expanding the electrochemical stability window of the electrolyte represents one of …

Unearthing Potential: Impact Investors’ Perspectives On Egypt’S Social Enterprise Market, Yousef Hesham Shoukry

Theses and Dissertations

This thesis examines impact investing in Egypt from the vantage point of the impact investors, revealing that Egypt's constraint is not the availability of capital but its direction, as the absence of legal recognition, coordinated intermediaries, and a shared impact-measurement standard keeps capital out of a market otherwise rich in social enterprise potential. The study employed a constructivist grounded theory approach, drawing on eleven semi-structured interviews with impact fund managers, ecosystem enablers, and public-sector policy advisors operating in or considering Egypt's social enterprise market. Data revealed that practitioners converge on the founding principles of impact investment (combined financial and social …

Policy Coherence And Private Sector Development In Egypt: Aligning Governance Reforms With Development Finance, Shereef El Tanahi

Theses and Dissertations

Despite record volumes of development finance flowing into Egypt, the private sector, particularly its micro, small, and medium enterprises, has yet to experience the broad-based growth these investments were designed to catalyze. Between 2020 and 2025, international development partners committed more than 15.6 billion dollars to Egypt's private sector, yet private investment remains a modest share of the national economy, and most domestic firms continue to face severe barriers to credit.

This thesis argues that the answer lies not in the volume of capital mobilized, but in the coherence of the policies that govern how that capital reaches firms. The …

Simulation-Based Assessment Of Operational And Retrofit Solutions For Effluent Compliance Of A Capacity-Limited Oxidation Ditch Wwtp, Ahmed Sameh Harash

Theses and Dissertations

Oxidation-ditch wastewater treatment plants (WWTPs) across Egypt's Nile Delta are increasingly carrying hydraulic and organic loads beyond what they were designed for. This work can be considered pioneering as this work compared operational and structural retrofit alternatives for such a plant within a single verified simulation framework. The present study fills that gap by building a digital twin of the Qaha WWTP, a dual-train Carrousel oxidation ditch in Qalyubia Governorate, calibrated to a baseline flow of 7,420 m³/day in the SUMO24 platform (a third-generation, open-source wastewater treatment process simulation software) using the SUMO2c biokinetic model (a simplified variant of Activated …

Circulating Futures: Infrastructure, Value, And The Making Of Contemporary Egypt, Yasmine Abdeldayem

Theses and Dissertations

Since 2014, Egypt has undertaken an unprecedented expansion of its road network as part of a broader project of territorial development and national renewal. Roads are presented in this project as the connective infrastructure through which new cities, investment zones, and desert territories are brought into circulation. Yet their developmental effects are often difficult to discern: infrastructure is rapidly built but unevenly maintained, while projects justified in terms of mobility, growth, and public benefit can produce dispossession, exclusion, and new forms of risk. This thesis argues that roads cannot be understood solely through the developmental outcomes they are intended to …

Dynamic Baseline Schedule Updates Using Digital Twinning: A Case Study On Aluminum Formwork Construction, Ahmed Hamdi Sweilam

Theses and Dissertations

Repetitive high-rise construction using aluminum formwork couples consecutive floor cycles through a reused panel set and a floor-level inspection and pour barrier, so productivity loss compounds upward rather than being absorbed locally. The baseline schedule is nevertheless fixed before execution and is not revised as evidence of realized productivity accumulates. This thesis develops a simulation-based digital twin that updates the baseline from observed as-built durations and acts on its own forecast. A discrete-event simulation of a ten-story residential tower is built in AnyLogic® and verified analytically at 180.00 hours per floor. After each completed floor the twin infers activity productivity …

A Maximum Energy Release Rate Computational Framework For Fatigue Crack Trajectory And Life Prediction Under Mixed-Mode Proportional And Nonproportional Loading, Nahla Helmy Matar

Theses and Dissertations

The problem of mixed-mode fatigue crack growth has been a persistent research challenge. The determination of fatigue crack propagation direction directly impacts the safety and integrity of components and structures, making it crucial in various industrial applications, including welded drilling pipes, aerospace, and automotive engineering. Unlike uniaxial loading, mixed-mode cracks tend to change direction frequently (kinking), and nonproportional loading adds to the complexity of the problem. This research aims to estimate the crack propagation direction and fatigue crack life in linear elastic materials subjected to mixed-mode (I+II) loading conditions under proportional or non-proportional cyclic loading. Numerical software was developed based …

This study develops and evaluates a web-based interactive application for the Qalawun Complex in Cairo, a fourteenth-century Mamluk monument of significant tangible and intangible cultural heritage value, with the aim of enhancing visitor engagement beyond the passive observation that characterizes most heritage visits. The research is structured within an Asset-Design-Evaluate (ADE) framework and grounded in Radical Constructivism, Situated Learning theory, and the Design-Dynamics-Experience (DDE) framework, positioning the physical architecture of the site as the primary source of visitor knowledge through observation-based interaction tasks.

The application, titled "Qalawun's Treasure," comprises eight spatially anchored hotspots across the mausoleum, madrasa, and bimaristan of …

Technology, Power, And Colonial Modernity: The Making Of The Egyptian Railways, Ahmed Mohamed Rahmy

Theses and Dissertations

This thesis examines Egyptian railways as a technology of power through which modern temporal order was gradually formed, reorganized, and contested. Focusing on the period from 1850 to 1920, it argues that railway infrastructure did more than facilitate mobility, economic exchange, and imperial administration: it reorganized the temporal relations through which social life was governed and experienced. Timetables, standardized schedules, fares, penalties, stations, and administrative procedures made punctuality, regularity, and measurable time appear as neutral requirements of life, while positioning existing ecological, agricultural, religious, and communal rhythms as signs of backwardness.

The thesis draws on British official correspondence, parliamentary debates, …

An Assessment Of Carbon Dioxide Removal Potential From Stormwater Ponds Using Concrete-Based Materials, Yu-Hsuan Tai

Theses and Dissertations (Comprehensive)

Stormwater ponds (SWPs) are engineered stormwater infrastructure known to be major greenhouse gas (GHG) emitters, including carbon dioxide (CO₂). Concrete-based materials have great potential to capture CO₂ as carbonate minerals (CaCO₃), through aqueous carbonation, driven by their alkaline nature and high portlandite (Ca(OH)₂) content. However, the mechanistic understanding of how specific parameters including mass, surface area, and degradation of calcium silicate hydrate (C-S-H) phases collectively control carbonation kinetics and CO₂ uptake under dynamically evolving conditions remains underexplored. Laboratory-scale experiments were conducted to evaluate the effects of cement dosage, particle surface area, and …

Endogenous Light In The Brain: Investigating Sources, Propagation, And State-Dependent Emission, Emre Cicek

Theses and Dissertations (Comprehensive)

Ultraweak photon emission (UPE), and by extension light, has long been thought to be a modality of communication in nature. Prior studies have already identified that UPE can depend on cell type and can be used to discern between malignant and benign cells. However, besides theoretical models, not much effort has been made to identify possible biological structures that would allow for light to be used as a method of communication in the human body. According to the framework set by Shannon’s Information Theory, for communication to be possible at minimum a transmitter, a transmission channel, and a receiver are …

Logupdater: Automated Detection And Repair Of Specific Defects In Logging Statements, Renyi Zhong, Yichen Li, Jinxi Kuang, Wenwei Gu, Yintong Huo, R. Michael Lyu

Research Collection School Of Computing and Information Systems

Developers write logging statements to monitor software runtime behaviors and system state. However, poorly constructed or misleading log messages can inadvertently obfuscate actual program execution patterns, thereby impeding effective software maintenance. Existing research on analyzing issues within logging statements is limited, primarily focusing on detecting a singular type of defect and relying on manual intervention for fixes rather than automated solutions.To address the limitation, we initiate a systematic study that pinpoints four specific types of defects in logging statements (i.e., statement code inconsistency, static dynamic inconsistency, temporal relation inconsistency, and readability issues) through the analysis of real-world log-centric changes. We …

Optimizing Human Fcrn Mouse Models To Improve Pharmacokinetic Evaluation Of Antibody Drug Candidates., Gregory J. Christianson, Zachary M Howard, Samantha Kenney, Emily Lowell, Nijaguna Bethur, Derry C. Roopenian, Elena Gonzalo-Gil

Faculty Research 2026

The use of animal models that can reliably predict drug performance in human patients is critical to antibody therapeutic development. Along with assessing toxicity and efficacy, determining the pharmacokinetic (PK) properties of therapeutics in Tg32 and Tg276 mice is essential to preclinical characterization. While Tg32 mice have been well established as indispensable in their ability to model the PK properties of antibody therapeutics, their intact immunity leaves them capable of mounting anti-drug antibody responses that interfere with PK interpretation. Here, we demonstrate the negative impact anti-drug responses can have on PK parameters derived from Tg32 mice, and provide strong evidence …
