Tornado Hazard and Exposure Model for Canadian Communities

Tornadoes are the most disastrous, violent and lethal wind events in the world. In the United States, more than 4,000 fatalities and US$20 trillion in damages were reported between 1950-1994. Recently on September 21st 2018, an outbreak of six tornadoes devastated the Ottawa-Gatineau area in Canada causing damages that might approach US$100 million. Due to the rise in tornado events in recent years, it is expected that the insurance industries and home owners will be more interested in tornado risk mitigation.

Anthropogenic impacts on the population dynamics of a critically endangered marine mammal

Economic development often has dire consequences for wildlife and environmental conservation. In Taiwan coastal waters, a small dolphin population is being affected by large-scale habitat loss and degradation resulting from development projects, pollution, vessel traffic and a massive fishing industry.

Adaptive Algorithm for End Point Estimation in Steel Making Refining and its Industrial Application

In the steelmaking industry, process control models need to be based on a sound physical understanding of the process but should also account for many uncertainties due to the nature and complexity of the environment in which the process is carried out. As a result, it is crucial to extract useful process control information from the raw data stream acquired by the industrial sensors.

Improving the properties of active pharmaceutical ingredients by polymorph, salt and cocrystal screening

Solids exist as crystals, amorphous or subcooled liquids. The degree of crystallinity determines the long range order in a solid phase. Molecules when transferred from the solution to the solid phase may take many different crystal forms (polymorphs, solvates/hydrates, salts, co-crystals). Theoretically, there are 230 space groups describing the diversity of a crystalline material. About two thirds of pharmaceutical small molecules exist in more than one polymorphic solid form. Crystallization of polymorphs still has a touch of art.

The anti-Helicobacter pylori properties and mechanism of action of probiotic Lactobacilli secretomes

Helicobacter pylori (HP) is a bacterium that causes 65% of gastric ulcers and cancers worldwide. Current anti HP treatments often fail because the bacteria have become resistant and they have serious side effects. We are looking into using molecules produced by bacteria called Lactobacilli that are a natural component of the human gastro-intestinal flora to treat and/or prevent Helicobacter infections. The novelty of our approach is to focus on the molecules that Lactobacilli release (i.e. their secretions) and that could be administered to patients in a controlled and reliable manner.

Automatic Spondylolisthesis Grading

Approximately 5% of the population has a Spondylolisthesis (one of the lower vertebrae slips forward onto the bone directly beneath it). Non-invasive image-based assessment of this spinal structure is an increasing demand in healthcare service. However, the massive information embedded in the increasing large imaging scans has made manual inspection a lengthy and tedious task and observer dependent. The proposed research aims at a computer-aided spinal-scan assessment software toolkit facilitating the diagnosis of Spondylolisthesis.

Accelerate development of new technologies and applications for advanced water treatment

Global population growth, urbanization and changing climate patterns have increased the demand for potable water, wastewater reuse and value recovery from wastewater, and for remediation of industrial process water. Population growth also results in increased demand for the shipping of goods by ocean freight, with the associated risk of the transport of unwanted marine life from one location to another by the discharge of ballast water.

Modelling and Experimental Validation of the Interaction of Multiple Mercury Arc Lamps in Ultraviolet (UV) Reactors

Trojan Technologies uses ultraviolet (UV) lamps in reactors to purify water. When multiple lamps in a reactor are active at once, light emitted by the various lamps can interact with neighbouring lamps, creating effects that are not well taken into account in current industrial lamp models. The goal of this project is to develop a more accurate model, which accounts for these phenomena, to better predict the distribution of UV light inside a reactor. To do this, we have developed a numerical model of the photon-plasma interactions, which agrees well with work found in the literature.

Development of a model for dynamic cyclone performance prediction

Global pollution emissions contribute to climate change and are damaging to health. In many industrial applications that produce particulate matter, devices such as cyclones are used to separate and capture the particles from the exhaust gas. However, these do not capture the very small, but hazardous, particles and so expensive and energy-intensive secondary systems have to be added to the process. The industrial partner is developing a novel dynamic cyclone separator that has rotating vanes which improve the particle separation efficiency and allow capture of the fine particles.
