In the operation of CANDU reactors, the Zr-2.5Nb pressure tubes holding the cooling water and fuel bundles are susceptible to hydride cracking-induced crack initiation mechanisms, known as delayed hydride cracking and overload crack initiation. For structural integrity evaluation of CANDU pressure tubes, of fracture toughness and hydride crack initiation models were developed. However, the hydride […]

Reaction Dynamics is a small-satellite launch vehicle company aiming to build a launch vehicle using a revolutionary type of rocket propulsion. Launch vehicles rely on a sophisticated Guidance, Navigation, and Control algorithm to precisely navigate and stabilize their vehicle during flight. The company requires an innovative method to accurately deflect the thrust force of the […]

The aero-engine design process is highly iterative, multidisciplinary and complex in nature. The success of an engine depends on a carefully balanced design that best exploits the interactions between numerous traditional engineering disciplines such as aerodynamics and structures as well as lifecycle analysis of cost, manufacturability, serviceability and supportability. Pratt & Whitney Canada (P&WC) is […]

The depletion of fossil fuels and the negative impacts of their extraction and combustion on the environment have encouraged scientists and industrial stakeholders to explore the development of alternative, and renewable energy resources such as bio-oil, which can be produced from biomass by pyrolysis and bio-oil upgrading. The main disadvantages of crude bio-oils derived from […]

This project applies wide-bandgap (WBG) transistors to voltage level multiplier module (VLMM) topology in motor inverter applications. It is expected that this approach can yield the benefits of WBG motor inverters (high motor efficiency, fast control response, lower motor torque ripple, close to ideal sinusoidal motor current waveform, smaller filter size, lower cost filter, etc.) […]

Workspace Interferences/Collisions happen on construction jobsites when multiple resources (labor, equipment, material, etc.) don’t have enough space to coexist at the same time and will interfere with each other’s operations. These interferences affect performance, delaying the project, impacting cost, and may jeopardize the buildings’ integrity and people’s safety on site. Most of existing models simulate […]

Selon Skate canada, près de 180 000 Canadiens pratiquent le patinage artistique de façon structurée, dont 10% représentent l’élite. La réception de sauts en patinage artistique implique de grandes forces d’impact, représentant environ 3 à 9 fois le poids corporel de l’athlète. La répétition de cette mise en charge excessive au niveau articulaire mène éventuellement […]

description should also indicate the expected benefit to the partner organization. (Approx 150 words) Since the advent of rail transportation, the integrity of the rail and track conditions play a significant role in ensuring that trains are able to move people safely. As track infrastructure is impacted by ambient temperature and normal wear and tear, […]

Le marché énergétique est en transition. La demande et la consommation d’énergie dans le secteur résidentiel seront impactées par l’adoption de nouvelles technologies et l’évolution des comportements. Le projet de recherche vise le développement d’un modèle statistique générant des profils temporels individualisés de présence des individus à leur résidence en fonction des attributs des individus. […]

NORAM Engineering and Constructors have a technology called salt splitting. This technology is used to produce caustic soda and sulfuric acid. However, the presence of fluoride in this technology can cause the breakdown of the coating on the titanium anode, which can cause premature anode failure. As replacing these titanium anodes can incur significant costs, […]

This project is a collaboration between Triptech Engineering and Software Services LTD and Laboratory for Alternative Energy Conversion (LAEC) at SFU to develop data analytics solutions for PEM fuel cell industry. The fuel cell industry is suffering from component/system failure and coping with analysis of tremendous amounts of data. Knowledge extraction from this complex data […]

For the realization of amplifiers with ultra-high control bandwidth, typically the series connection of high-frequency PWM H-bridges is considered in order to simultaneously achieve multi-level voltages and high effective switching frequency, which enables the required high cut-off frequency of the output filter and, thus, facilitates high control bandwidth. However, the approach is of high complexity, […]
