Risk aggregation beyond the normal limits

Risk aggregation is omnipresent in insurance applications. A recent example, borrowed from the modern regulatory accords, is the determination of the aggregate economic capital and its consequent allocation to risk drivers. A more traditional illustration of the importance of risk aggregation in insurance is the celebrated collective risk theory that dates back to the early years of the 20th century. This project will assist Sun Life Financial to build and implement an efficient quantitative framework to approximate the aggregate risk of its portfolio.

Hybrid Distributed Energy Resources for Net-Zero Energy Buildings

The main objective of the project is to develop hybrid distributed energy resource (HDER) systems to supply energy to net-zero energy commercial and residential buildings. This is expected to result in lower energy costs to consumers and utilities and in greater reliability of the grid. The HDERs will consist of solar panels, generators, and batteries. They will supply buildings with energy whenever possible and feed any excess energy to the grid. The grid will supply energy to the buildings whenever energy from the HDERs is insufficient.

Advanced Anode Materials for Next-Generation All-Solid-State Lithium Batteries

Advanced batteries are critical for achieving high-performance electric vehicles (EVs) and supporting goals to reduce greenhouse gas emissions. The prevailing rechargeable Lithium-ion batteries (LIBs) using liquid electrolytes, are the major choice for current EVs. However, these LIBs still suffer from safety, lifespan, and energy density issues.

Multilingual Semantic Similarity Engine

To communicate with their end users, businesses regularly produce written documents such as letters, notices, statements, etc.., in various languages. A set of rules are usually used to ensure that information in these documents is 'correct' and consistent across languages and communication channels. However, with the increasing volume and variety of information being sent out to clients, it becomes difficult to preserve the semantics of client messages across vocabulary and language variations.

Application of Lystek thermal-alkaline hydrolysis technology to fermentation of primary sludge and waste activated sludge

In this research proposal, we are targeting volatile fatty acids production by subsequent Lystek thermal-alkaline hydrolysis technology followed by fermentation. In these two subsequent processes, organic solids will be converted first thermochemically followed by biologically to volatile fatty acids. To enhance wastewater treatment, phosphorus and nitrogen should be removed to a certain level before discharging into water bodies. However, the challenge here an additional carbon source is required which increases the total cost of the treatment.

Lifestyle and cognition: a large-scale approach - Year two

Online cognitive testing provides unprecedented opportunities for exploring human brain function among the general population. Cambridge Brain Sciences Inc has created an online cognitive testing platform that has attracted more than 1.5M users and has hosted more than 300 studies of cognition. This research plans leverage their unique dataset to explore the interrelationship between demographic and lifestyle factors, and cognitive performance on a massive scale.

Computational fluid dynamics modelling of heat pipes for cooling applications

The proposed project aims to develop numerical models using computational fluid dynamics (CFD) to understand and predict the performance of heat pipes in the context of cooling applications. Heat pipes are a type of enhanced heat transfer device that uses a continuous cycle of boiling and condensing a fluid to transfer heat at a very high rate. The industry partner designs and manufactures heat pipes that are used extensively in the cooling of molds for making automotive parts.

Development of Chitosan-based Nanosparticles forLoading Non-water Soluble Medicine

Over 90% new drugs cannot be used in market or perform inefficiently because of their poor water-solubility. Delivery of non-water soluble medicine by using biodegradable carriers can solve the problem. This research work aims to develop N-trimethyl chitosan chloride (TMC)-based nanoparticles used as a drug carrier for delivering non-water soluble medicine to enhance the therapeutic efficiency. Two interns will be involved in this project. Collaborating with Ovensa Inc., we will produce TMC-based nanoparticles with suitable particle size and surface properties.

A hidden history: Gentrification in four London, Ontario Heritage Conservation Districts (HCDs)

Heritage Conservation Districts (HCDs) in London Ontario are a success story of architectural heritage preservation. There has been a rapid expansion of designated districts in the city, with the first appearing in 1992 and six more in the years since, with seven more currently on the books. This research will consider residents who relocated outside of the City’s four earliest HCDs post designation, and the reasons for their movement. An animated map will be created, displaying the data in both space and time.

Biomaterials for the reduction of bacterial adhesion and biofilm formation

Stents are tubes placed between the kidney and the bladder which prevent blockages which might otherwise damage the kidney. Introducing foreign material into this system allows a platform for bacteria to exist and which will potentially cause infections. These are very common. We propose modifying the surfaces of the materials used in stents to make them “non-stick” to prevent bacteria attaching and then causing infections. We can test this in the laboratory and wish to test different types of material under different conditions which mimic the clinical environment.
