Electrical and Computer Engineering Faculty Research and Publications

This paper investigates upgrading aging three-phase Permanent Magnet Assisted Synchronous Reluctance Machines (PMaSynRMs) into multiphase configurations—specifically six- and five-phase windings—without modifying the existing stator or rotor laminations. This retrofit supports circular economic principles by extending machine life and reducing material waste and cost. Four configurations are examined: the original three-phase winding, asymmetrical six-phase winding, symmetrical six-phase winding, and five-phase winding. The feasibility of rewinding existing three-phase stators is explored for different slot/pole combinations. Balanced rewound five-phase windings are feasible only when the stator's slot/pole ratio is greater than or equal to 9. Both symmetrical and asymmetrical rewound six-phase windings are …

Mixed Quantum/Classical Theory Approach To Rotationally Inelastic Molecular Collisions Implemented On A Quantum Computer, Jonathan Andrade-Plascencia, Tamila Kuanysheva, Dulat Bostan, Brian K. Kendrick, Dmitri Babikov

Chemistry Faculty Research and Publications

All elements of a quantum algorithm for calculations of rotationally inelastic molecule + atom scattering within the framework of a mixed quantum/classical theory are outlined. In this approach, the rotational motion of the molecule is described quantum mechanically using the time-dependent Schrödinger equation, while the scattering process of two collision partners is treated classically. The matrix of potential coupling is precomputed on a classical processor, whereas the quantum hardware is used to propagate the system of coupled equations for the rotational state-to-state transitions. All quantum circuits needed for practical implementation of the algorithm are presented. First, the quantum codes written …

Quantum Simulation Of Molecular Dynamics Processes─A Benchmark Study Using A Classical Simulator And Present-Day Quantum Hardware, Tamila Kuanysheva, Brian K. Kendrick, Lukasz Cincio, Dmitri Babikov

Chemistry Faculty Research and Publications

We explore how the fundamental problems in quantum molecular dynamics can be modeled using classical simulators (emulators) of quantum computers and the actual quantum hardware available to us today. The list of problems we tackle includes propagation of a free wave packet, vibration of a harmonic oscillator, and tunneling through a barrier. Each of these problems starts with the initial wave packet setup. Although Qiskit provides a general method for initializing wave functions, in most cases it generates deep quantum circuits. While these circuits perform well on noiseless simulators, they suffer from excessive noise on quantum hardware. To overcome this …

The Influence Of Human Presence And Footprint On Animal Space Use In Us National Parks, Kaitlyn M. Gaynor, Forest P. Hayes, Kezia Manlove, Nathan Galloway, John F. Benson, Michael J. Cherry, Rolf O. Peterson, Sarah Hoy, John Vucetich, Et Al.

Michigan Tech Publications

Given the importance of protected areas for biodiversity, the growth of visitation to many areas has raised concerns about the effects of humans on wildlife. In 2020, the COVID-19 pandemic led to temporary closure of national parks in the United States, offering a pseudonatural experiment to tease apart the effects of permanent infrastructure and transient human presence on animals. We compiled GPS tracking data from 229 individuals of 10 mammal species in 14 parks and used third-order hierarchical resource selection functions to evaluate the influence of the human footprint on animal space use in 2019 and 2020. Averaged across all …

Mtu-Llm: Llm-Based Multi-Robot Task Allocation And Path Planning For Heterogeneous Robots In Search And Rescue Operations, Kaushik Kannan, Jungyun Bae

Michigan Tech Publications

Urban Search and Rescue operations after natural disasters involve locating and assisting victims in hazardous environments, which is challenging. Classical Multi-Robot Task Allocation (MRTA) and path planning approaches have been used to deploy heterogeneous robot teams in unsafe areas. However, existing methods often lack focus on workload balance and requirement fulfillment and struggle to generalize across different scenarios. To address these challenges, we propose Multi-robot Task allocation Utilizing LLMs (MTU-LLM), a framework designed to reduce the development time for task allocation and path planning approaches, enabling faster robot deployment. The framework uses an LLM-based “prompt engineering” approach that generates task …

Understanding Grade 10 Learners’ Mathematics Learning Experiences In Rural Schools: Applying The Self-Determination Theory, Hlamulo Wiseman Mbhiza, Thabisile Nkambule

The Rural Educator

The increasing performative expectation in mathematics continuously positions rural learners in a deficit manner within the education system in post-apartheid South Africa. The often-cited low academic performance of rural learners in mathematics fosters the belief that something is wrong with their mathematical learning abilities. The problem with narrow and often decontextualized perspectives of rural learners is that their interactions with mathematical content are frequently overlooked in education research. The purpose of this study was to critically explore grade 10 rural learners’ mathematics learning experiences. We employed a qualitative descriptive approach within a case study design, using semi-structured individual interviews supported …

Smith, Jean O'Dwyer, Paul D. Hynds, Martin Cormican, Liam P. Burke

Research Outputs: 2025-Present

Consequences of Shiga toxin-producing Escherichia coli (STEC) infection can range in severity from asymptomatic infection to haemolytic uraemic syndrome, renal failure and death. Groundwater-derived drinking water is an important route for STEC transmission. Detection of STEC in water is crucial for timely response and public health interventions; however, currently used culture-based methods are time-consuming and laborious. Therefore, there is a need for rapid methods that maintain high sensitivity and specificity [1]. We describe a novel, sensitive, enrichment-free water filtration method using a convenient sample volume (100 ml) to detect DNA markers of STEC serogroups and virulence factors within 6 h. …

Faculty, Staff and Student Publications

Introduction: Patients' perceptions about synthetic mesh for ventral hernia repair (VHR) may stem from a lack of knowledge of risks. We assessed patients' threshold for accepting the risk of hernia recurrence to avoid synthetic mesh.

Methods: Patients ≥18 y old with prior or upcoming VHR viewed a one-time video decision aid describing recurrence risk with biologic versus synthetic mesh. Patients chose between these options using a probability trade-off (PTO) technique, varying hernia recurrence rate with biologic mesh. Based on randomized trials, the recurrence rate using synthetic mesh was 9%. The PTO score was the recurrence rate (0%-100%) at which patients …

Expanding Equity And Innovation In Pharmaceutical Law And Drug Development: Paying Clinical Trial Participants For Their Data, Steve Calandrillo, Bernadette Tosti, Jefferson Smith, Jamison Koeman

Articles

Bringing a drug to market is exceedingly expensive and exposes pharmaceutical manufacturers to significant legal risk. But when companies are successful, their profits make the PowerBall jackpot look like petty cash. Staggering rewards measure in the billions or millions for the firms, CEOs, pharmacies, drug benefit managers, data brokers, and many more actors in the pharmaceutical-to-patient pipeline. The only individuals who don’t get paid handsomely are the clinical trial participants, whose voluntary participation and data helped make those successes possible. It is long past time that we reform the legal and regulatory roadblocks to paying clinical trial participants in the …

Governing Migration, Producing Skills: Emigration And Education In The Philippines, Yasmin Y. Ortiga, Roderick. Galam

Research Collection School of Social Sciences

This article examines skill as an integral yet understudied aspect of emigration governance. To date, migration studies have mainly focused on how the demand for migrant skills drive people's movements across borders, shaping the conditions for entry into popular destinations in the West. In contrast, less is known as to how skills also shape the way governments manage emigration, pushing would-be migrants to acquire certain capacities well before they leave their countries of origin. Drawing from the case of the Philippines, this article discusses how state agencies have used skills training to dominate specific markets for migrant professionals and demand …

Stockpiling, Forecasting And Protecting Skills: Skilling As Technique Of Preparedness In Times Of Crises, Rebecca Ye, Yasmin Y. Ortiga

Research Collection School of Social Sciences

In this comparative and situational analysis, we examine how nation-states use skilling as a technique of preparedness during crisis moments. By analysing two strategically selected country cases, Singapore and Sweden, during a critical phase of a global pandemic, we identify three techniques: stockpiling, forecasting, and protecting skills, and how these were enacted as a means to perform preparedness. Stockpiling skills was observed to take place as a rapid response; forecasting skills was a technique enacted with a view on the longer-term horizon and protecting skills was mobilised as a short-term future technique, where boundaries were assembled around skilling. While there …

Manufactured Superiority: The War On Terror, United States Dominated Media, And The Global Implications Of American Exceptionalism, Ayan Mohamed

Undergraduate Theses and Capstone Projects

This research examines American exceptionalism and its effects on the global perception of the United States, specifically how it shapes international narratives, marginalizes alternative perspectives, and reinforces a ruling American worldview that inhibits effective engagement and cross-cultural dialogue. The study will focus on two key areas: U.S. military interventions and media representation. First, it will analyze the War on Terror in Afghanistan and Iraq (2001–2021), assessing how U.S.-enforced destabilization in the region perpetuates hegemonic control. Second, it will investigate U.S.-backed, Israel-led Palestinian erasure as a case study of interventionism that positions the U.S. as the self-designated enforcer of global order. …

Re-Reading Power Inside The Aml-Ctf Regime, Sanaa Ahmed

Dalhousie Law Journal

Money laundering and money laundering controls are having a global moment. Many jurisdictions around the world—some more than others—feature regularly in news cycles for either offences to do with money laundering or sanctions avoidance or the laxity of controls that enable such activities. The mainstream media has reported on stories about banks in Canada and football clubs in Italy, about charities in the UK and the real estate industry in the US. Each revelation prompts mea culpas from offenders—TD Bank in Canada is one such example—and often, a raft of new or enhanced regulatory measures.

Critically, the point that remains …
