Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Laboratory friction measurements are central to material screening for High-Friction Surface Treatments (HFST), yet metrological aspects including a proposed metrological traceability framework or uncertainty, and reproducibility are consistently underreported. This study applies a metrology-aligned framework to British Pendulum Tester (BPT) measurements performed in three states: dry, wet (water), and water–soap to assess operational adhesion and hysteresis components, document traceability to the International System of Units (SI), and report GUM-style uncertainty with covariance for the adhesion difference. Measurements were obtained for calcined bauxite (CB) and rhyolite (Rhy) in HFST and Coarse gradations across seven polishing protocols (baseline; LAA-1000/2000; MDA-105/180; PSV-10 h/20 …

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 …

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 …

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 …

Multiaxial Characterization And Machine Learning – Enhanced Modeling Of Anisotropic Materials For Forming Applications, Abrar Salam Ebrahim

Doctoral Dissertations

Reliable prediction of material deformation in forming processes requires constitutive models that accurately capture anisotropy while remaining practical to calibrate. This dissertation combines mechanical testing, full-field deformation measurements, finite element (FE) analysis, and artificial neural networks (ANNs) to address three complementary requirements: representation of complex material behavior, characterization across an expanded multiaxial loading space, and experiment-efficient identification of advanced anisotropic yield functions using machine learning. Chapter 2 develops a hybrid ANN-enhanced constitutive framework for Grade 1 commercially pure titanium (CP-Ti) sheet metal to describe temperature and strain rate-dependent hardening and anisotropy. Implemented in an Abaqus user material subroutine, the framework …

Systems Analyses For Sustainable Water Infrastructure Management: Road- Stream Crossings And Urban Drainage Networks, Koorosh Asadifakhr

Doctoral Dissertations

Road-stream crossings (RSCs) and municipal storm sewer networks convey water across and beneath the built environment, and their failure carries consequences for flood risk, aquatic habitat, and public safety. Much of this infrastructure is aging and incompletely characterized, and it is managed under simultaneous budget, coordination, and data constraints. Replacement needs exceed available funding, responsibility is divided among agencies with differing mandates, and asset inventories are maintained for operational rather than analytical purposes. Decisions with large and long-lived consequences are therefore made without the systematic analysis that would inform them. This dissertation develops systems analyses directed at that gap, combining …

Quantifying Greenhouse Gas Emissions And Mental Health Impacts As Co-Benefits Of Flood Risk Mitigation, Sebastian Rowan

Doctoral Dissertations

Flooding is the most perilous natural hazard in the United States. Flood risk has historically been mitigated by constructing flood defenses such as sea walls or levees that are designed to prevent flood waters from reaching developed areas. However, climate change is increasing the frequency and intensity of flood events beyond the magnitude for which many flood defenses were designed, and the presence of flood defenses has incentivized development within floodplains significantly increasing the consequences of flooding when these systems fail. Total annual flood risk in the U.S. has been estimated in the tens of billions of dollars; however such …

Enhancing Implementation Of Balanced Mix Design For Asphalt Mixtures Through Improved Material Selection, Cracking Characterization, And Performance Prediction, Shubham Harishbhai Modi

Doctoral Dissertations

Balanced Mix Design (BMD) has emerged as a promising approach for improving asphalt mixture performance by balancing rutting and cracking resistance through performance tests rather than relying solely on volumetric criteria. Therefore, its application is increasingly being explored by transportation agencies for both highway and airfield domains. Despite its advantages, several challenges still limit the widespread implementation of BMD. These challenges include uncertainties associated with the compatibility of asphalt mixture components, the limited practicality of existing cracking performance tests, and the lack of performance prediction tools suitable for process control during mixture production. This dissertation addresses these critical challenges by …

Cultural Food Security And Alternative Food Network Participation: Participatory Research With Sub-Saharan African Immigrants In The Northeastern United States, Luyue Zheng

Doctoral Dissertations

Sub-Saharan African (SSA) immigrants are a growing population in the U.S. and experience a high prevalence of food insecurity. As many report challenges accessing healthy and culturally appropriate foods after migration, cultural food security is a growing concern. Alternative food networks (AFNs), such as farmers markets and community gardens, provide opportunities for immigrant communities to produce and access culturally important foods to support their cultural food security. Beyond improving food access, AFNs may also enhance the agency and sustainability dimensions of food security by creating opportunities for immigrants to produce, distribute, and access culturally appropriate foods through local food systems, …

A Systematic Study Of Solar Wind Tangential Discontinuity Inclination And Their Impact On Dayside Magnetospheric Dynamics Using Global Mhd Simulations, Neha Srivastava

Doctoral Dissertations

This dissertation presents a systematic investigation of how the inclination of solar wind tangential discontinuities controls the dayside magnetospheric response using global MHD simulations conducted with the OpenGGCM model. This study is motivated by the need to understand how TD orientation controls dayside magnetospheric response, and adopts the view that the bow shock (BS) and magnetopause (MP) can be treated as large-scale discontinuities, such that their interaction with an interplanetary TD may be interpreted as a nonlinear discontinuity–discontinuity interaction. Within this framework, the role of TD orientation in governing the coupled evolution of disturbances across the dayside magnetospheric system is …

Autonomy, Adolescents, And Artificial Intelligence, Michael J. S. Beauvais

Journal of Science & Technology Law

In this essay, I explore the potential implications of adolescent use of AI assistants on the development of adolescents’ capacities for autonomy. Thinking through these issues from the perspective of first principles is, I believe, needed in order to sharpen our understanding of some of the issues AI assistants pose for young people. A clear analysis will suggest which legal or policy prescriptions should follow.

I first give an overview of adolescent use of AI assistants, noting their popularity and the variety of use contexts. Drawing upon the work of Catriona Mackenzie, I then outline a relational conception of autonomy …

Central Bank Financial Strength, Credibility, And Global Market Risk: Evidence From Southeast Asian Economies, Mega Fauziah, Hermanto Siregar, Solikin M. Juhro, Tanti Novianti, Sigit Wibowo

Bulletin of Monetary Economics and Banking

This paper examines central bank credibility in the context of its financial strength, independence, and global market uncertainty in five Southeast Asian countries between 2005 and 2023. We find that the global market risk indicated by VIX reveals that these Southeast Asian economies, despite achieving considerable central bank independence and institutional development, remain fundamentally constrained by global market conditions in maintaining their credibility, measured by the difference between the inflation rate and its target in the same year. We argue that in emerging economies exposed to global uncertainty, central bank profitability, conditional on its independence, is vital for central banks …

Fiscal Decentralization, Local Government Size, And Regional Economic Growth: Evidence From Indonesia, Faizul Mubarok, Hasta Dwi Pradana, Etty Puji Lestari

Bulletin of Monetary Economics and Banking

This study investigates the dynamic relationship between fiscal decentralization, local government size, and regional economic growth in Indonesia. Integrating fiscal federalism theory with the Armey curve framework, the study examines whether decentralization reshapes the scale of subnational governments and how this influences growth outcomes. Using balanced panel data from 26 Indonesian provinces over the period 1995–2020, the analysis employs dynamic panel estimators based on the Generalized Method of Moments (GMM) to address endogeneity, persistence, and unobserved heterogeneity. The results reveal a nuanced relationship between fiscal decentralization and government size. Greater revenue autonomy is associated with a contraction in government size …

Oil Futures Reactions To Monetary Policy Surprises: A High-Frequency Analysis, Syed Mujahid Hussain Dr., Basel Awartani, Farrukh Javed, Iqbal Khadaroo Dr., Nader Virk Dr.

Bulletin of Monetary Economics and Banking

This study examines how oil futures respond to monetary policy shocks arising from FOMC and ECB target-rate announcements, using high-frequency data. The results indicate that both sets of announcements significantly influence oil futures prices. However, FOMC decisions have a more pronounced effect on oil futures, whereas ECB interest rate surprises predominantly have a limited impact on the oil futures return and volatility. The analysis further uncovers an asymmetric response to positive versus negative interest rate shocks. These findings enhance the understanding of how monetary policy surprises are transmitted to oil futures markets. Therefore, these results have important implications for policymakers …
