Optimization Of Bonding Behavior Of Crumb Rubber-Modified (Crm) Asphalt For Sustainable High-Friction Surface Treatment (Hfst) Applications, Abdallah Aboelela, Magdy Abdelrahman

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Binder bonding strength (BBS) is critical to aggregate retention and friction performance in high-friction surface treatment (HFST). Although epoxy resin is traditionally used, asphalt-based binders offer a sustainable alternative; however, their bonding behavior and influence on polishing performance remain insufficiently understood. This study investigated the evolution and optimization of BBS in crumb rubber-modified (CRM) asphalt for rhyolite-based HFSTs. BBS was measured under dry and wet-conditioned states for two CR contents (10% and 15%), two CR types (cryogenic and ambient), two interaction temperatures (170 and 200 °C), and interaction times from 10 to 240 min. HFST performance was assessed using the …

Flexural Performance Of Deficient Rc Beams Repaired With Gfrp Composite, Zena Aljazaeri, Hayder Alghazali, Zuhair Al-Jaberi, John J. Myers

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Fiber-reinforced polymer composite materials have been improved for use in repairing and strengthening existing infrastructure over the past few decades. This case study focuses on the effect of confinement with GFRP strips on the structural performance of out-of-service beams in bridge applications due to the impact of over-height vehicles or inadequate lap-spliced reinforcements. In this study, beams with inadequate lap splices in the tension zone were utilized to mimic the damaged area in out-of-service RC beams. The proposed repair technique is a glass fiber-reinforced polymer (GFRP) composite in the form of longitudinal sheets and U-wrapped strips. The experimental study determined …

Faculty, Staff and Students Publications

Estrogen receptor-positive (ER+) breast cancer exhibits a marked propensity for skeletal metastasis; however, the molecular drivers of bone colonization remain incompletely defined. We investigated the tumor suppressor neurofibromin (NF1), a dual repressor for RAS and ER signaling, whose inactivation promotes endocrine therapy (ET) resistance and is associated with inferior relapse-free survival. NF1 copy number loss was detected in 62% of ER+ patients who subsequently developed metastases and was associated with an increased likelihood of bone metastases at initial diagnosis. In mouse xenograft models, NF1-depleted ER+ breast cancer cells demonstrated enhanced dissemination to skeletal sites following surgical resection of primary tumors. …

Michigan Tech Publications

Cardiovascular disease is a leading cause of global mortality, driving the need for non-invasive early detection methods. Analysis of specific volatile organic compounds (VOCs) in exhaled breath, such as acetone, hexane, hexanal, isoprene, and pentane, offers a promising diagnostic pathway. However, the selective detection of these low-concentration VOC biomarkers remains a significant challenge. This study employs a combination of theoretical approaches, such as density functional theory (DFT), STM-based tunnelling model aligned with the Tersoff-Hamann approximation, and thermodynamic analysis via the Langmuir adsorption model, to assess the sensing capabilities of two-dimensional (2D) MBenes (Mo2B2Tx) monolayers toward the targeted VOCs. The results …

The Coming Health Insurance Transition, Brendan S. Maher

Faculty Scholarship

For decades, the dominant form of private health insurance in the United States—by far—has been employment-based group health insurance. Somewhere in the range of 175 million employees and their families receive health care coverage through a system in which employers serve as financiers, procurers, administrators, and fiduciaries of the health insurance promise. An overwhelming percentage of those health insurance arrangements are governed by ERISA, with little room for state law.

That is going to change.

This Article explains—for the first time anywhere—why and how. Because of the tremendous and as-yet unrecognized power of an obscure-sounding funding arrangement called the Individual …

Assessing The Impact Of Quantum Technology On Smart City Cyber Resilience, Afra Almansoori

Theses

Smart Cities rely on high-density digital infrastructures that include Internet of Things (IoT) devices, Artificial Intelligence (AI), cloud computing, digital identity systems, and operational technology. Although these systems improve efficiency and sustainability, they also provide a large cyber-physical attack surface. The problem is exacerbated by the advent of quantum computing, as popular public-key ciphers like RSA and elliptic-curve cryptography can be broken using quantum algorithms such as Shor's algorithm (Shor, 1994; Mosca, 2018). Smart cities rely on long-term data confidentiality, certificate-based trust, and remote management of critical infrastructure. This presents a strategic cyber resilience challenge. This thesis examines the impact …

Machine Learning Based Detection Of Unaccounted For Water Using Smart Water Meter Data, Uhoud Aljarman

Theses

The increasing deployment of smart water meters has transformed water distribution systems by enabling high-resolution, near real-time monitoring of customer level water consumption. In water scarce regions such as the Middle East and North Africa (MENA), and particularly in the United Arab Emirates (UAE) where potable water production relies predominantly on energy intensive desalination, these data streams present a critical opportunity to reduce Unaccounted-for Water (UFW), also referred to as Non-Revenue Water (NRW). UFW arising from physical leaks, meter malfunctions, unauthorized connections, and abnormal consumption patterns imposes significant economic, operational, and environmental burdens on water utilities (World Bank, 2016; World …

Deterring Political Deceit: A Constitutional Argument To Defend The People's Democracy (2026), David Chang

Books

More than ever, influencers and politicians communicate political messages that they do not believe to be true. This political deceit is constitutionally valueless, harms public discourse, and impedes effective public decision-making. Yet, under current doctrine, the Supreme Court would invalidate any regulation of deceitful political advocacy as an abridgment of political speech.

In Deterring Political Deceit, David Chang explores why traditional efforts to target falsity in political speech have been rooted in constitutional error. While the Court has determined that the defamation of public officials is unprotected, it wrongly declared that false statements of fact lack constitutional value, and …

ECU-MALNETT (ECU MALware NETwork Traffic) is a real world, reproducible dataset of labeled benign and malicious network flows built from the Peekaboo execution corpus. Peekaboo runs evasive malware with dynamic binary instrumentation and records raw host-level PCAPs while granting full Internet access, yielding noisy, real-world captures with background OS activity and concurrent processes. To derive trustworthy labels from these traces, we apply Construct, a baseline aware, zero-trust labeling framework. Construct first ingests a baseline capture to establish reference sets (DNS qnames, HTTP hosts, TLS SNIs, and socket endpoints) and grows a conservative benign IP pool only via whitelisted DNS resolutions. …

From Green Presence To Perceived Greenery: Everyday Mobility And Perceptual Availability In Singapore, Ziheng Zeng, Sonny Rosenthal, Orlando Woods

Research Collection College of Integrative Studies

Urban greenery may be abundant in transit-oriented cities, yet green presence does not necessarily become perceptually available to people moving through it. This paper distinguishes green supply, perceived greenery, and green experience, and examines the step at which greenery enters awareness during travel. The study combined 21 days of ecological momentary assessment from 68 participants in Singapore, yielding 6,794 in-trip moments, and 25 route-reconstruction interviews. A satellite normalized difference vegetation index (NDVI) provided a top-down baseline of green supply, and a street-level green view index (GVI) from Google Street View (GSV), matched to 5,824 moments, provided a co-located eye-level baseline. …

The Stickiness Of Meritocratic Beliefs From Adolescence To Adulthood In Singapore, Yen Kiat Chong, Shin Bin Tan, Vincent Chua, Han Ei Chew

Research Collection Office of Impact

The belief in meritocracy has been rising over the past few decades in developed countries. While many studies have focused on the belief in meritocracy, its distribution across groups and its effects, much less is known about how beliefs may change as individuals age and undergo major life transitions. Using linear growth models on three waves of panel data from a national youth survey in Singapore, we found that the major life transitions to adulthood – progressing through the education system (e.g., completing tertiary education), transiting from full-time studies to full-time work, getting married and becoming a parent – predicted …

This study isolated a Pseudomonas sp. closely related to the Pseudomonas aeruginosa from oil-contaminated soil near Kashy Refinery (Duhok Province, Kurdistan Region, Iraq) and evaluated its biodesulfurization potential as an environmentally friendly alternative to hydrodesulfurization. Batch experiments were conducted at 34 °C and atmospheric pressure using mineral salts medium supplemented with 1%, 3%, and 5% (v/v) Tawki crude oil. The highest sulfur removal efficiency of 83.33% was obtained at 1% (v/v) crude oil after 10 …

Intracommunity Social Capital Systems Of Class And Caste In South Asian Intimate-Partner Violence Survivor Outcomes, Vriddhi Vinay

Dissertations, Theses, and Capstone Projects

This study theorizes how caste and class function as transnational forms of social capital that structure intimate partner violence (IPV) outcomes among South Asian diasporic women in the New York City metropolitan area. While existing IPV scholarship foregrounds migration status, gender, and legal precarity, it often treats South Asian communities as internally homogeneous and overlooks how intracommunity hierarchies mediate access to support. Drawing on social capital theory and postcolonial feminist frameworks, this research positions caste and class stratification as underexamined axes of stratification within United States-based IPV analysis. Using survey data from 24 South Asian woman-identifying IPV survivors in New …

Role Of The Corticostriatal Pathway In Learning With Interoceptive Nicotine Stimulus, Tyler Allen

Doctoral Dissertations

Tobacco use, primarily smoking, is the leading preventable cause of death, causing eight million deaths annually. Nicotine, the main addictive constituent of tobacco, acts as a reinforcer and as an interoceptive conditioned stimulus. While its pharmacology is well studied, the neural mechanisms of learning with nicotine remain underexplored. We examined the role of prelimbic cortex (PL) projections to the anterior dorsomedial caudate putamen (a-dmCPu) in nicotine-evoked goal-tracking. To achieve pathway-specific inhibition, we expressed Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) in male and female rats. Subsequently, rats underwent self-administration conditioning in which active responses delivered intravenous (IV) nicotine followed …

Enhancing Structural Design Methodologies For Pavements Incorporating Engineered Emulsion Stabilized Cold Recycled Materials, Ebubechukwu Uche Al-Ihekwaba

Doctoral Dissertations

The transportation sector is confronted with the necessity of sustainability, and the utilization of recycling techniques in the construction and rehabilitation of asphalt pavements has emerged as a viable strategy for preserving pavement infrastructure. Among the various recycling methods, cold recycling is distinguished by its efficient reutilization of existing pavement materials, ease of mix preparation & construction, and reduced dependence on virgin materials and fossil fuels, thereby contributing to lower emissions. The three primary cold recycling techniques, cold in-place recycling (CIR), cold central plant recycling (CCPR), and full-depth reclamation (FDR), differ in their construction methodologies, material processing approaches, and the …

Influence Of Material Composition And Constitutive Representation Of Cold Recycled Asphalt Mixtures On Mechanical Response And Pavement Performance, Fausto Bisanti

Doctoral Dissertations

Cold recycling technologies provide a sustainable approach for pavement rehabilitation by reusing existing materials while reducing the consumption of virgin resources, transportation requirements, production temperatures, and construction-related environmental impacts. However, the mechanical response of cold recycled mixtures (CRM) differs from that of both conventional hot mix asphalt and unbound granular materials and is influenced by material composition, volumetric characteristics, confinement, curing, and stress state. These characteristics create uncertainty regarding material selection, mechanical characterization, and the prediction of the structural contribution of cold recycled layers. Further opportunities to enhance the sustainability of cold recycling lie in the incorporation of alternative recycled …

Reliable Gait Analysis With Context-Aware Wearable Sensor Systems, Stella Abena Ansah

Doctoral Dissertations

Accurate gait analysis is important for clinical assessment, rehabilitation monitoring, fall-risk evaluation, sports performance analysis, and the control of assistive devices. While wearable sensor systems offer practical solutions for estimating key gait parameters outside the laboratory, their accuracy is often affected by sensor noise, drift, activity-dependent movement patterns, and changes in sensor response over time. These challenges limit their practical use in real-world settings, where continuous ground-truth validation and repeated laboratory calibration are not always available.This study addresses these challenges by developing context-aware wearable sensing methods for reliable gait analysis during everyday activities. The proposed approaches use information about the …
