Development And Validation Of A Subject-Specific Integrated Finite Element Musculoskeletal Model Of Human Trunk With Ergonomic And Clinical Applications, Farshid Ghezelbash, Amir Hossein Eskandari, Amir Jafari Bidhendi, Aboulfazl Shirazi-Adl, Christian Lariviere

Études primaires

Biomechanical modeling of the human trunk is crucial for understanding spinal mechanics and its role in ergonomics and clinical interventions. Traditional models have been limited by only considering the passive structures of the spine in finite element (FE) models or incorporating active muscular components in multi-body musculoskeletal (MS) models with an oversimplified spine. To address those limitations, we developed a subject-specific coupled FE-MS model of the trunk and explored its applications in ergonomics and surgical interventions. A parametric detailed FE model was constructed, integrated with a muscle architecture, and individualized based on existing datasets. Our comprehensive validation encompassed tissue-level responses, …

Capacitive ECG signals with observable R peaks (after filtering) could be captured with almost all pairs of textile electrodes, independently …

Label-Free Visualization And Segmentation Of Endothelial Cell Mitochondria Using Holotomographic Microscopy And U-Net, Raul Michael, Tallah Modirzadeh, Tahir Bachar Issa, Patrick Jurney

Faculty Research, Scholarly, and Creative Activity

Understanding the physiological processes underlying cardiovascular disease (CVD) requires examination of endothelial cell (EC) mitochondrial networks, because mitochondrial function and adenosine triphosphate production are crucial in EC metabolism, and consequently influence CVD progression. Although current biochemical assays and immunofluorescence microscopy can reveal how mitochondrial function influences cellular metabolism, they cannot achieve live observation and tracking changes in mitochondrial networks through fusion and fission events. Holotomographic microscopy (HTM) has emerged as a promising technique for real-time, label-free visualization of ECs and their organelles, such as mitochondria. This nondestructive, noninterfering live cell imaging method offers unprecedented opportunities to observe mitochondrial network dynamics. …

A Privacy-Preserving Federated Learning Approach For Airline Upgrade Optimization, Sien Chen, Yinghua Huang

Faculty Research, Scholarly, and Creative Activity

Purpose: A key issue of making upgrade decisions is to match the most relevant upgrade offers to the right customers at the right time. To optimize upgrade strategies and profitability, companies seek to break “data silos” between themselves and other business partners for a more holistic view of customers' consumption experiences. However, multi-source data fusion may lead to potential privacy leakage. To overcome these two challenges in data silos and privacy protection, this study introduced a privacy-preserving federated learning (FL) approach and explained the process of using FL in modeling airline passengers’ willingness to pay for upgrade offers.

Cultivating Plain Language Skills For Engineering Students, Catherine Wong, Cynthia Carlson

Faculty Publications

While engineers are learning the vocabulary of the profession, understandably, they want to practice, and perhaps show their professors that they are proficient. This leads to student writing that is overly complicated and full of jargon. This is not the type of document that would be clear to the public, or even to a professional outside of the narrowly focused field of the particular engineer. After graduation, engineers’ writing becomes exponentially more important. Often approval of projects relies on residents’ or clients’ understanding of engineers’ work. For example, an engineering firm completing an investigation of an important health concern such …

Doctor of Ministry Projects

Problem

The three multicultural, multi-ethnic (MCME) churches in my district were facing tension among members from diverse cultures, ethnicities, countries of origin, and languages. Factions formed cliques and vied for leadership roles, while some groups appeared to dominate the worship services. Certain members became upset when people with difficult accents from specific language groups led out in services and could not be understood. Others shared their distinctive foods only within their own groups. Some members felt isolated and believed they lacked a voice.

Method

Nine seminars and workshops were organised to raise awareness among the MCME congregants about the causes …

Multi-Scale Dynamic Modeling, Validation, And Uncertainty Quantification Of Radial Flow Fixed Bed Contactors For Co2 Capture, Ana Flávia De Alencar Arraes Monteiro

Graduate Theses, Dissertations, and Problem Reports (ETD)

One of the key sources of carbon dioxide emissions to the environment is fossil fuel combustion for power generation. Post-combustion CO2 capture using amine-based solvents is currently the most matured process. However, amines are corrosive and lead to degradation products at even moderate temperatures generating environmental pollutants, and require high energy for regeneration. Solid sorbents are a promising alternative. They possess lower regeneration energy, thermal stability, and have highly tunable porous structures with large surface area that can help in achieving high loading and high adsorption rates. This work focuses on mathematical modeling of CO2 adsorption/desorption processes using solid sorbents. …

Efficient And Test-Time Adaptive Visual Object Tracking In The Wild, Ram J. Zaveri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tracking a single object, given the location at the first frame, has been an ongoing challenge in the vision community for decades. Most recent approaches provide reasonably good performance, especially when benchmarked on in-distribution (ID) datasets, i.e., on the testing portion of the same datasets used for training. However, they incur high computational costs and hardware constraints, making their deployment in the wild for mobile, autonomous, and IoT applications still challenging. Efficient visual trackers address the efficiency aspect of such bottlenecks; however, they tend to overfit to their training distributions and lack generalization abilities, resulting in them performing well on …

La Valse And The Parisian Salon: Nostalgic Continuities And Sonorous Modernisms, Claire Weydt

Graduate Theses, Dissertations, and Problem Reports (ETD)

Immediately following World War I and the death of prominent French composer Claude Debussy, French composers and music critics were concerned that the war created an unbridgeable chasm between generations of composers who, through their various aesthetic allegiances, worked to define musical sounds as undeniably French. Numerous scholars have characterized this process as an aesthetic rupture brought on by the World Wars. French composer Maurice Ravel (1875-1937), however, seems to have bridged this gap, at least for some influential critics. My project challenges notions of wartime rupture by resituating musical modernism within a framework of aesthetic continuity. Ravel’s choreographic poem …

The Effect Of Sars-Cov-2 On Bacterial Diversity And Abundance In Community Wastewater, Joshua Lambert

Graduate Theses, Dissertations, and Problem Reports (ETD)

Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) enters human respiratory cells through binding of its spike (S) protein to the ACE-2 receptor, which is highly expressed in lung cells, but is also found in over 150 other cell types encompassing major organs including GI enterocytes. SARS-CoV-2 causes gut dysbiosis in infected individuals and patients with COVID-19 and also coincides with lower alpha diversity of the individual’s gut microbiome. Certain gut microbiome-associated genera are lower in abundance in COVID-19 patients including Lachnospira, Prevetolla, Roseburia, Bifidobacterium, and Faecalibacterium while genera such as Bacteroides, Enterococcus and Proteobacteria are increased during a SARS-CoV-2 …
