Predictive Control Approach to Convert Single-Zone Residential Buildings with Central HVAC Systems to Multi-Zone Systems

The current project aims to develop a novel energy management strategy for residential heating ventilating and air conditioning (HVAC) systems. Controllable wireless air damping vents will adjust the air flow in different zones of the building allowing independent control of the temperature which results in enhanced thermal comfort and energy savings. The intern will collaborate with the partner organization on studying a novel predictive model to control the damping factor of the vents within fully closed to fully open range.

Portable sensor for rapid and onsite detection of bacteria in water

The presence of harmful bacteria in drinking water sources can seriously harm the population that receives the contaminated water. The current standard methods for testing drinking water for bacteria heavily rely on using central laboratories. For small rural communities that are far from these laboratories, this scheme may represent 2-7 delays until they find out about the quality of their drinking water sources. This can be catastrophic if the residents of these communities drink contaminated water while waiting for the results.

Automation of Low-Energy Welding Process for Aerospace Applications and Contactless Approach

Mechanical failure is a significant issue in the aerospace industry. High material and manufacturing costs make the component repair an attractive option, avoiding the need to scrap parts when defects are detected. Low Energy Welding (LEW) is a micro-welding process that offers several advantages in repairing sensitive high-cost components. Extensive work has been carried out with the manual process. However, the process is relatively slow and the manual process is difficult to maintain constant quality.

Study of unplugging sand control devices using shock waves

This research aims at better understanding the performance of Wireline Applied Stimulation Pulse (WASP) technique in formation damage reduction in oil and gas wells. Hydrocarbon production rate decreases as a result of plugging the sand control devices located in the wellbore region. Shock waves generated by the WASP technique help breaking the sources of formation damage into smaller pieces; As a result, small particles can be carried to the surface.

Tool Development for Bolus Shaping in Radiation Therapy

During External-Beam Radiotherapy in cancer therapy, Bolus, a thick sheet of flexible material, is used to cover the skin surface in order to minimize damage healthy tissues. A significant problem of using bolus is air gaps generated between the bolus and patient’s skin if an inaccurate shape of bolus was made. In this research, an efficient process of shaping and cutting bolus will be developed to improve the efficiency and efficacy of bolus forming in order to minimize the air gap. This new approach utilizes an unfolding and folding method.

Advanced Control and Monitoring Systems for Autonomous Snow Removal Equipment at Airports

Airports in Canada have the difficult tasks of needing to remain open during adverse weather conditions in the winter. The research that we are undertaking is to develop and deploy a fully autonomous snow removal equipment for Canadian airports. Operating a snowplow is a dangerous and exhausting task for human operators, often they are unable to see clearly when they are operating in extreme conditions. Airports are also finding it increasingly more difficult to recruit and retain seasonal workers. A potential solution for these issues is a fully autonomous snow removal system.

Advanced Thermal Solutions for Telecom Systems Synopsis

This project is a collaboration between NORSAT International Inc. and Laboratory for Alternative Energy Conversion (LAEC) at SFU to commercialize novel and efficient cooling solutions for NORSAT ATOM series BUCs and SSPAs. NORSAT amplifiers are typically 15-20% efficient meaning up to 85% of the applied electrical power is dissipated as heat. The heat is removed by means of several ways in the current design e.g. heat sinks, heat pipes, and fans which is about 50% of the amplifier size.

Development and characterization of graphene/glass fiber/polyester composites

Polymeric matrices containing nano-size additives have demonstrated remarkable mechanical, electrical, and thermal properties when compared to their micro-composite counterparts. Inserting graphene in a polymer matrix consisting of a glass fiber-reinforced resin is assumed to significantly increase the material electrical conductivity, which is needed in order to fulfill electrical conductivity requirements traditionally met by carbon black incorporation.

Service Life Predictions for Machined Components of Nickel-based Superalloys

Nowadays in aerospace industry, the main concern is to reach an optimum, reliable, and reproducible manufacturing process with a high predictability of the components’ service life and the lowest production cost. Machining is one of the main manufacturing processes for industrial parts which can change the surface characteristics of materials. The main aspects of these alterations are metallurgical, topographical, mechanical, and thermal which could affect microstructure, roughness, and residual stresses at the surface and near the surface of machined components, respectively.

Tribo-electrostatic Separation of Potash

Over two years a post-doctoral fellow will investigate the electrostatic separation of potash. This will be accomplished experimentally by triboelectrically charging different materials, with and without conditioning agents, and then testing different separation techniques. Separation techniques will include electrostatic separation and a fines removal process.
