Physics-Informed Machine Learning-Aided Framework For Entrainment Fraction In Gas-Liquid Two-Phase Annular Flow, Anadi Mondal, Subash L. Sharma

Nuclear Engineering and Radiation Science Faculty Research & Creative Works

The liquid film flow rate or droplet flow rate in annular flow is determined by a parameter known as the entrainment fraction. Conventional empirical correlations are commonly employed for predicting the entrainment fraction; however, their applicability is often restricted to specific operating conditions and working fluids. Recently, a few machine learning (ML) models have been developed to achieve better accuracy in entrainment fraction prediction. However, these models are completely data-driven, meaning they are good for prediction in the interpolated domain, but exhibit limited generalization capability in the extrapolated domain. To address this limitation, a physics-informed machine learning-aided framework (PIMLAF), combining …

Anterior Cutaneous Nerve Entrapment Syndrome From Glucagon-Like Peptide-1 Receptor Agonist Injection, Neha Singh, Elisa Chaparro, Jordan Michael Shapiro, Emanuel Narcis Husu

Faculty, Staff and Students Publications

Anterior cutaneous nerve entrapment syndrome (ACNES) is an underdiagnosed cause of abdominal pain. We report the first documented ACNES case following subcutaneous administration of glucagon-like peptide-1 receptor agonist. A 44-year-old man developed focal, neuropathic abdominal pain coinciding with initiation of tirzepatide injections. Clinical examination confirmed ACNES diagnosis, and pain improved after relocating injections away from the abdomen and initiating multimodal pharmacotherapy. This case emphasizes the need to consider ACNES in patients endorsing focal abdominal pain with concurrent use of glucagon-like peptide-1 therapy and highlights injection site modification as a simple, effective management strategy while exercising self-restraint with respect to workup.

Research outputs 2022 to 2026

Blue carbon ecosystems (BCEs), including mangroves, salt marshes, and seagrasses, play a critical role in climate mitigation due to their high carbon sequestration capacity. Despite Africa's extensive and diverse coastal ecosystems, continent-wide assessments of blue carbon stocks and accumulation rates remain scarce. Here, we synthesized blue carbon data from 87 publications (January 1993 - March 2026) to evaluate the current state of knowledge and regional variability. Our analysis reveals marked regional heterogeneity in sediment organic carbon (SOC) stocks across Africa, reflecting both ecological variability and methodological differences among studies. Normalised to a sediment depth of 1 m, median SOC stocks …

A Novel Multi−Agent Deep Reinforcement Learning Framework For Fast Frequency Response In Inverter−Based Hybrid Power Plants, Muhammad Ikram, Asma Aziz, Daryoush Habibi

Research outputs 2022 to 2026

The increasing penetration of inverter−based resources (IBR) in power grids necessitates novel control techniques to deliver advanced ancillary services such as fast frequency response (FFR), crucial for ensuring power system stability. Existing schemes−droop control, virtual synchronous generator (VSG), and hybrid approaches−require full observability, and centralized control, which are unsuitable for utility−scale hybrid power plant (HPP) with a distributed grid−forming inverter (GFMI). In addition, it lacks adaptive control capabilities in response to real−time disturbances according to the IEEE 2800−2022 standard. To address these challenges, this paper proposes a design of a novel multi−agent deep reinforcement learning (MADRL) framework for utility−scale IBR−dominated …

Georoad-Upernet: Geo-1-Based Weakly Supervised Multispectral Road Extraction Via Role-Aware Context Fusion And Semantic Regularization, Shaoqian Chen, Yunliang Chen, Jianxin Li, Ao Yang

Research outputs 2022 to 2026

Extracting roads accurately from remote sensing images is important for map updates, traffic analysis, and infrastructure monitoring. Medium-resolution multispectral images can provide useful surface and background information, but when used alone, the spatial details are limited for retaining narrow roads, intersection structures, and fine road topologies. To address this problem, this paper proposes GeoRoad-UPerNet, a Geo-1-centered weakly supervised multispectral framework for road extraction. In this framework, Geo-1 serves as the primary 16-band multispectral source, Sentinel-2 Level-2A imagery serves as auxiliary contextual support, and OpenStreetMap (OSM) road information is converted into proxy supervision rather than dense manual ground truth. GeoRoad-UPerNet contains …

Optimizing Fpga And Wafer Test Coverage With Spatial Sampling And Machine Learning: Analysis Of Local Spatial Consistency, Weiquan Wang, K. M.Shahriar Alam Adib, Foisal Ahmed, Riaz Ul Haque Mian

Research outputs 2022 to 2026

Wafer and FPGA testing remains costly in semiconductor manufacturing. This paper studies random sampling, stratified sampling, and k-means sampling under a partial-measurement setting with Gaussian Process Regression (GPR), and introduces Short Distance Elimination (SDE), a spatial screening rule that spreads selected training points over the layout. Combining value-based sampling with SDE yields two hybrid methods: S-SDE, which applies SDE within stratified subsets, and K-SDE, which applies SDE within k-means clusters. A calibration-based protocol fixes the value-group labels and SDE thresholds before target-file prediction. The SDE thresholds are selected from (Formula presented.) configurations in (Formula presented.), excluding (Formula presented.), using local …

Aviation Accident Investigation Analysis Methodologies Used By 12 Government Safety Investigation Authorities, Kym Bills, Leesa Costello, Marcus Cattani

Research outputs 2022 to 2026

Introduction: Leading government Safety Investigation Authorities (SIAs) that investigate major aviation accidents are members of the International Transportation Safety Association (ITSA). Investigation analysis methodology details are rarely included on SIA websites, in final accident reports, shared with peers, or specified by the International Civil Aviation Organization (ICAO). Some ‘New View’ safety researchers assume SIAs don't use systemic methodologies and that accident investigation has little value. Because of the sensitivity of SIA work and need to prioritize safety value from available investigation funding, there has been little academic research on choice and use of investigation analysis methodologies to address these issues …

Centring Girls In Water Justice Research And Social Movements, Cecilia Chitukula, Wrigley, Julie Nyanjom, Naomi Joy Godden

Research outputs 2022 to 2026

Scholars and activists focused on water justice in the Global South are increasingly embracing collaborative methods. These methods include community-centred research, public engagement in water management, and participatory interventions aimed at addressing the crisis of fresh and clean water access in both urban and rural localities. This represents a shift from state-led water management that is top-down, technocentric, and privatised, towards just and equitable water solutions which are informed by the needs of community members. In patriarchal societies of the Global South, girls are disproportionately affected by the water crisis, as they are tasked with water searching and fetching responsibilities …

Research outputs 2022 to 2026

Recent evidence has suggested an association between high sodium intake and development of cognitive impairment. However, while animal studies demonstrate consistent relationships between sodium intake and cognitive impairment, this relationship remains less clear in humans. Our aim was to investigate the relationship between self-reported baseline sodium intake and cognitive decline over 72 months. Cognitively unimpaired participants (n = 1208) from the Australian Imaging, Biomarkers and Lifestyle study were included (70.87 years of age; 41 % male). Participants completed a food frequency questionnaire to quantify sodium intake and underwent comprehensive neuropsychological assessment at baseline and four additional timepoints, 18 months apart. …

Experimental Game-Based Learning: A Serious Game Experiment In Purchasing And Supply Management, Vincent Delke, Frederik G. S. Vos, Holger Schiele

Business Faculty Publications and Presentations

To better prepare higher education graduates for the early stages of their careers, universities aim to bridge the gap between classroom teaching and the skills demanded by industry, particularly in the field of procurement. Today, procurement professionals increasingly require specialised skill sets, rather than generalist education, to effectively fulfil their role-specific responsibilities. This study integrates experiential learning theory with game-based learning by presenting a synthesised model that unites both perspectives. Building on this model, a purchasing-specific game is employed to compare traditional lecture-based teaching with experiential game-based learning, focusing on purchasing skills as well as cognitive and affective learning outcomes. …

The External Influence Of International Business Scholarship: Growth, Stabilization, Or Decline?, Gokhan Ertug, Andrew Delios, Yi Li, Zhengchu Zhang

Research Collection Lee Kong Chian School Of Business

The influence of international business (IB) scholarship is an active debate (e.g., Bello & Kostova, 2012; Cantwell et al., 2014, 2016; Doh et al., 2023; Tung et al., 2023). Although IB research has expanded in the number of publications, in its sophistication of research design, and in its thematic breadth over the past decades, questions remain regarding its influence beyond the core ecosystem of IB journals. Anecdotally, a pessimistic view has become more commonplace. The concern is that IB has become increasingly self-referential, relying more heavily on IB-related theory extensions and context-specific settings, which could limit its resonance in the …

Rehab Mechanics, Sierra Spierling, Nicole Garcia, Joel Gonzalez, Diana Garcia-Becerra, Mia Kwan

Mechanical Engineering Senior Theses

Stroke survivors often struggle to regain grip strength and hand mobility due to limited access to physical therapy, lack of progress tracking during independent rehabilitation sessions, and reduced motivation from slow or unmeasured progress. There is a need for more effective rehabilitation approaches, as current at-home strengthening tools do not provide quantitative feedback or adjustable resistance, and clinical devices are expensive. This makes it challenging for patients and their physical therapists to guide recovery and monitor improvement effectively. To address these obstacles, we developed a low-cost, customizable grip-strengthening device that tracks patient progress and assists in regaining strength and mobility …
