The Mercedes-Benz Fuel Cell Division (MBFC) in Burnaby, Canada develops and runs the manufacturing processes required for the assembly of Fuel Cell Stacks prototypes. MBFC uses the Manufacturing Execution System (MES) to collect and analyse data from the manufacturing lines to the database system. However, because the size of the collected data is very large, […]

Modern electric power systems are complicated, large-scale dynamical systems that need specialized tools and techniques for their computer modeling and simulation. This is due to the unprecedented penetration of renewable energy sources and use of high-frequency power electronic converters. This proposal aims to develop algorithms and methods for co-simulation of modern power systems using dynamic […]

In order to move towards a sustainable future, it is essential to develop environmentally friendly fuels for energy production. Hydrogen and ammonia are promising candidates for clean fuels as they do not harm the environment when utilized as fuels. Ammonia is one of the leading chemicals produced throughout the world. However, the hydrogen gas required […]

In commercial batteries, metal anode-based batteries, mainly using zinc or lithium as the anode, provide higher battery capacity than traditional metal ion batteries. Lithium metal anodes have a theoretical specific capacity 10 times higher than commercial lithium ion batteries with graphite as the anode. Zinc anodes are excellent anodes for use in aqueous batteries, because […]

This study focus on the understanding of radiation-induced embrittlement in CANDU reactor spacer material, Inconel X-750. The helium pre-implantation following by proton irradiation will be employed as a surrogate for neutron irradiation to simulate the radiation damage on the microstructure of Inconel X-750. Micro-tensile test on irradiation X-750 material will be carried out to evaluate […]

The proposed research aims at increasing the efficacy of tidal turbines by incorporating light-weight and resilient blades into a currently used turbine. For that, a recently developed 3D fiber-metal-laminate (3D-FML) material at Dalhousie University will be used. In comparison to metals that are presently used to form blades, or potentially fiber-reinforced composites, the 3D-FML would […]

Discontinuities of service, variations in voltage magnitude, and distortions in AC voltage waveforms constitute the different aspects poor power quality. A poor quality of power supply can cause malfunction of sensitive equipment and interrupt industrial processes, resulting in significant economic losses. Utilities and consumers are taking actions to maintain the power quality set by the […]

Internet of Things (IOT) enabled communication devices have become a ubiquitous commodity in the smart metering solutions world for the purposes of “getting the data off the meter”. Many of these devices have little to no measurable security, aside from the infamous “security through obscurity” which we can no longer rely on, as the average […]

Turbulence is a significant issue at every site being considered for instream tidal energy development. This turbulent flow creates fluctuating forces on tidal turbine blades and support structures, reducing turbine performance and shortening turbine lifespan. Thus, improving and validating numerical models of turbulence and turbine operation in turbulent flow is necessary to better predict device […]

Micro-scale particles composed of high-voltage spinel LNMO (LiNi1-xMnxO4) will be characterized using electron microscopy techniques. These particles are stabilized through the inclusion of coating materials. The methods to prepare these particle coatings consisted of either an in-situ or post-synthetic method. The interface between the particle and the coating will be characterized at the atomic-scale by […]

Due to its versatility, time and cost saving, additive manufacturing (AM) technology, and more specifically selective laser melting process (SLM), is replacing conventional manufacturing processes, particularly for producing complex geometry components. In this technology, the near net shape parts are incrementally built by fusing layers of powder material using an intensive heating source/ Structural stress […]

Modern power systems wherein renewable energy sources are prevalent will exhibit larger frequency deviations than conventional power systems due to the diluted share of conventional generation based upon large electric machines with massive spinning rotors. To combat this, power-electronic converters that are used to interface renewable sources need to provide ancillary, such as frequency support […]
