The University of Saskatchewan (U of S) specializes in developing and building instruments which make detailed measurements of the composition of the atmosphere. These measurements provide a key link to the Earths climate system and are important in estimating and predicting air quality. The U of S has partnered with ABB Inc. to develop an instrument called LIFE which measures greenhouse gases. This internship will focus on developing software to control and acquire data from the instrument. The intern will study LIFE and the programming system used by ABB.
This project focuses on the concept design and ACS/Geolocation simulation of an Earth-observation microsatellite in Low Earth Orbit. MSCI has a long history of building microsatellites, but not for an Earth observation mission. In this research, we will evaluate the current MSCI multi-mission bus design capability, given its current hardware, for use in the QEYSSat microsatellite mission proposal. QEYSSat is a proposed mission to create a quantum link between ground and space using polarized photons and to transmit encryption keys to ground based users using this link.
Aero-engines are lightweight structures which are assembled of several thin walled cylindrical components (casings). Casings are joined by bolted flanges, and must withstand high forces. To accurately predict the response of casings assembly, the non-linear behavior of the casing joints must be considered. Currently, aero-engine manufacturers (i.e PWC) are facing serious limitations in matching the experimental results with FE models prediction tools of the aero-engine.
This project aims to develop a fast-response, portable and mobile-readable point of care test (POCT) device. Three-dimensional (3D) printing technology is proposed to fabricate the configuration that features components and elements functioning to accommodate and integrate all principle stages of analysis, including sample pre-treatment, fluidic manipulation and signal detection.
Glacial Isostatic Adjustment (GIA), also known as Postglacial Rebound, describes how the Earth responds to different loading/unloading processes, through deformation and vertical motion. One important loading/unloading process includes the Wisconsinan Glaciation Episode and the last glacial maximum, approximately 21ka BP. The unloading processes since led to vertical motion centered around James Bay/Hudson Bay, Canada, with uplift rates up to 12 mm per year. The spatial distribution of vertical motion differs which leads to differential vertical motion of the Earth surface.
When waste rocks generated by mining activities are exposed to the air and water, various toxic elements may be released to receiving waters and soils. Arsenic (As) is known as one of the most toxic pollutants which can cause damage to the environment and human health. To implement effective source control, it is essential to identify key factors that control the leaching process. The main objective of this research is to determine the rate-controlling steps in the release of toxic elements, with the initial focus on arsenic release.
This research project studies a specific component in the commercial aircraft engine called the squeezed film damper, or SFD. The SFD is applied to reduce the vibration of the engine rotor, which in turn reduces the noise and brings comfort to the passengers. The expected delivery from this project includes an advanced SFD model which will be used by P&WC for the simulation of engine vibration. The developed model can also be studied as the guideline for an upgraded level of SFD design.
Healthcare organizations in British Columbia currently lack an eHealth system as a network of multiple data sources to manage EHRs in meaningful ways. To support clinician decision in operational needs, this project will investigate a cloud-based eHealth system to improve the scalability and interoperability of health information system. A data integration system and an online analytic processing system will be designed and incorporated in the cloud.
Cu and Ni minerals that have great economic value mostly exist in the form of sulfides, making them difficult to extract using hydrometallurgical processes. Currently, heap leaching is the most economical way to extract these metals from low grade ores. Copper recoveries of many chalcocite heap leaches report around 70% copper recovery. However, the chalcocite leaching reaction has several stages. The first stage leach is characterized by 50% copper extraction and the conversion of chalcocite into a second stage of covellite (CuS) which is very difficult to leach at ambient temperature.
Li-ion batteries (LIBs) are currently the most important power source for a wide variety of applications such as cell phones, laptops, computers and other portable electronics. They are also considered as very promising storage/power systems for future electric/hybrid-electric powered transportation. Although clever cell design and improvements in cell subcomponents can bear potential for volume and weight reduction, major developments in high energy density cathode and anode active materials are essential.
