With the ever increasing concerns about the structural adequacy of buildings and infrastructures, particularly in harsh environments with limited funding for ongoing maintenance, a significant need exists to develop highly durable and rapidly constructed structural systems. To this aim, recent...
Mathematical modeling and experimental validation of thin low platinum content and functionally graded cathode catalyst layersDownload
Low catalyst content remains a key requirement for the commercialization of polymer electrolyte fuel cells (PEFCs) into the energy, transportation, and material handling sectors. Understanding the fundamental phenomena reducing fuel cell performance at various stages of operation play a major...
Numerical Characterization of Ultrasound Elastography for the Early Detection of Deep Tissue InjuriesDownload
Deep tissue injuries - casually termed "bedsores" or "pressure ulcers" - are a type of wound often suffered as secondary injuries in persons with reduced mobility such as those with spinal cord injuries, the elderly, and people with multiple sclerosis. Deep tissue injuries form when excess...
Modelling of PEMFC Catalyst Layer Mass Transport and Electro-Chemical Reactions Using Multi-scale SimulationsDownload
The focus of this work is on improving understanding of mass transport limiting phenomena occurring within the micro-structure of Polymer Electrolyte Fuel Cell (PEFC) Catalyst Layers (CL). Micro-scale models, namely agglomerates, are employed within multi-scale CL framework, to examine many...
An open-source two-phase non-isothermal mathematical model of a polymer electrolyte membrane fuel cellDownload
A comprehensive open-source two-phase non-isothermal MEA model including the microporous layer and accounting for multi-step reaction kinetics for the ORR and HOR is developed for the first time. The model is integrated into openFCST, an open-source FEM based fuel cell simulation framework. All...
Three important mechanical behaviors of microtubules in vivo, i.e., buckling, vibration and splitting are investigated with especial focus on their relevance to biological functions of microtubules. To study the vibration and buckling of a microtubule, we model a microtubule as an elastic beam...
Computer Simulation of Diagnostic and Therapeutic Applications of Ultrasound Propagation in Biological TissuesDownload
Ultrasound has been widely utilized in diagnostic and therapeutic clinical practices. Further development of the application of ultrasound in the clinical practices requires comprehensive understanding of the physics of ultrasound propagation in biological tissues. In this research, computer...
Finite Element Model of the Thermal Profile During Submerged Arc Welding with One and Two ElectrodesDownload
The submerged-arc welding (SAW) process is used extensively in the manufacturing of pipes. The heat flow introduced by the welding operation has a significant impact on the properties of both the weld metal and the heat affected zone (HAZ). The work presented in this thesis aims to develop a...
Polymer electrolyte fuel cells (PEFCs) operate with a ternary mixture of fuel and reactants. The majority of numerical models in the literature, including the in-house Open-source Fuel Cell Simulation Toolbox (OpenFCST) software, use Fick’s law of diffusion which is only valid for binary...
Steam assisted gravity drainage (SAGD) is one of the most popular methods used for heavy oil extraction in Canada. Of the existing sand control methods that can be used for SAGD, slotted liners can be considered among the superior ones in terms of their performance and cost of manufacturing. RGL...
