By incorporation of distributed power generation to passive distribution networks, these networks will change to active networks and the studies related to active networks should be considered for them. Disconnection of these networks from the upstream power system may let them operate in islanded mode (a micro-grid). One of the studies that should be considered is the transient stability. Due to the random parameters of micro-grids and active distribution networks, the most realistic method for transient stability analysis is the stochastic one.
This internship aims to develop a new computer method for simulation of large electric power systems. Simulation of these systems is challenging due to their complexity and size, which translates into massive computational loads. The new simulation method will be faster by using parallel computing, will be more customizable than existing methods, and will assist power system designers and operators to gain deeper insight into the operation of the power grid.
The project performs comparative study of simplified and rigorous approaches to analysis of lightning strike discharge through complex 3D structures of the power line towers and their grounding systems. Simplified models of the commercial tools such as PSCAD and TFlash will be compared to the new rigorous electromagnetic model (EM) based on full-wave algorithms analysis.
With 3D printing comes the capacity to create custom plastic components needed in orthopaedic implants between surgeries, as short-term and possibly long-term measures. This customization and flexibility comes at the cost of facing new challenges: how can we sterilize and clean a 3D printed product that cannot withstand high temperatures, and what effects do low temperature surface sterilization have on the plastics being printed?
Traumatic Brain Injury (TBI) is a significant health problem mainly because of its plausible prolonged sequelae and lack of objective measures for recovery. There are usually some disabling persistent post-TBI symptoms (mostly neurological) that do not respond to the current clinical and physical rehabilitation. This proposal aims to investigate the effect of a promising treatment for persistent post TBI symptoms, and to monitor TBI patient?s recovery by an objective technique along with standard clinical assessments.
China’s civil infrastructure planners often face significant challenges when considering ways to encourage sustainable transportation methods for the millions of workers that commute between the country’s residential and commercial districts. For Chinese research intern Shuheng Zhu, the city of Winnipeg, Canada is providing a special glimpse into the complexities of public transportation planning on a much smaller scale.
Researchers from academia and industry have recently shown interest in generating electricity from the kinetic energy of the water streams. Generating electricity using hydrokinetic turbines is an emerging technology and its development depends on the good understanding of the different aspects of the technology. In this project we measure and analyze the flow velocity and turbulence characteristics of tidal streams in the Alderney Race, one of the most suitable locations for hydrokinetic turbine farms.
As a major field of science, materials behavior plays vital role in engineering applications and various industries. Many researchers are investigating the properties of different materials to propose better and more reliable materials for different applications. Bulk metallic glasses are one of the most recent developments in material science. The aim of this research is to study the microstructural behavior of this type of materials, particularly Cu-Zr compositions that are capable of introducing some high strength and ductility characteristics.
A sustainable system is supposed to satisfy its stakeholdersâ social, financial, and environmental requirements. Although there are many studies to optimize design decisions in a sustainable system, limited research is found to consider multiple objectives in sustainable system design. We study Eco-Industrial Parks (EIPs) as a sustainable system where businesses and local communities collaborated together to share resources and infrastructure
to gain economic and environmental objectives.
High-energy astrophysics is a young, fast-growing field that has opened a new window to the invisible universe. X-ray spectroscopy is a particularly powerful tool to discover the nature of highenergy sources, since their physical properties are inferred by comparing physical models to observations. Therefore, methods for fitting models to data are of crucial importance. The standard approach is via local optimization. However, these methods suffer from a number of limitations. At the U.
