Understanding memory consumption in a distributed data analytics system

Data analytics has emerged as an important driver for economic success in many businesses and in the public sector. In healthcare, using data analytics promises to reduce costs and improve patient diagnostics and treatment. This project is a collaboration with a Vancouver-based company PHEMI Systems that provides data analytics solutions for healthcare and other industries. Our goal is to understand how to make data analytics system used by PHEMI and many others more efficient in terms of consumed resources while at the same time meeting the needs of privacy.

Emerging Building Systems and Wood Innovation

The primary objective of this project is to develop and test an innovation feedback platform and methodology that will help the Canadian construction industry overcome significant, industry-wide barriers to innovative uses of wood, and become confident in embracing new ideas, products and processes, thereby advancing the uptake of innovative timber solutions at home and abroad.

Arsenic release from arsenic-bearing minerals

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.

Simulation and analysis of light scatter in head mounted display lens

Head-mounted display (HMD) lenses can include a high degree of scattering (ghosting) which reduces brightness and contrast, and is distracting to the user. This can directly impact the utility of the device, if for instance some of the display is illegible because of excess light scatter and blurring. In this research, we want to investigate ways to model sources of light scattering in a HMD with freeform lenses, using non-sequential raytracing software.

Treating advanced retinal degeneration – rebuilding multiple co-dependent retinal layers with stem cells

Despite dozens of clinical trials (and countless animal trials) to regenerate the retina with stem cells, none have solved the challenge successfully. This is because the retina has many layers, and all layers are necessary in order to restore vision in patients with advanced retinal degeneration – ~1M patients in Canada and >50M worldwide. Here, we developed a strategy that stratifies a suspension mixture of subretinal graft (including stem-cell-derived RPE and photoreceptors) into correct orientation and layering resulting in replacement of the lost retinal layers.

The Core Connectors Initiative

The proposed study evaluates The Core Connectors Initiative (CCI), a high school-based suicide prevention program designed to help youth gain peer support skills and mental health knowledge. CCI involves two phases, a 14-module training phase and an action phase. Facilitators who have backgrounds in counselling psychology or related disciplines will pilot the program in 5 high schools. CCI is based on a peer education suicide prevention program, Youth as Gatekeepers (Ohlmann, Kwee, & Lees, 2014).

Mechanisms and Application of MFD Catalyst on the Leaching of Secondary Copper Sulfide - Year two

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.

Characterization and Pelletization of Refused Derived Fuel (RDF)

The key objective of this research is to test the Refuse-Derived Fuel supplied by ICC and investigate parameters Involved In making durable pellets from these residues. This will include conducting a series of pelletization tests with different mixture recipe, pre-conditioning of material as well as adding binders. The produced pellets will then be tested for their calorific value, chemical composition, chlorine content and ash content ICC plans to convert RDF to heat, and electricity through gasification.

Effective knowledge translation of evidence-based best practice for healthy lifestyle behaviours

The proposed research will support the effective knowledge translation of evidence-based best practice information related to healthy lifestyle behaviours (such as physical activity, healthy eating, smoking cessation, stress management, and alcohol moderation). Over a two-year period, the post-doctoral fellow will create a series of knowledge translation tools (including web- and smartphone-based applications) that can be used in the effective primary and secondary prevention of chronic disease through lifestyle behaviour modification.

Integrating high resolution remote sensing of multi-scale hydrogeomorphology into long-term river management - Year two

Large northward-flowing boreal rivers are an important hydroelectric resource, but effects of river regulation on downstream geomorphology and aquatic ecosystems are difficult to predict. Peace River, BC presents an ideal case study of river response to regulation, with continuous monitoring since dam construction in 1967. However, current understanding of system changes is based mainly on periodic ground-based measurements that may be less sensitive to characterize complexity at the scales at which the river responds.
