Development of Cold Spray Titanium Parts by Additive Manufacturing and Titanium Coated Composite Parts for the Aerospace Sector

Additive manufacturing (AM) is a promising field as a sustainable alternative to traditional manufacturing processes for the aerospace sector because of the potential of low buy-to-fly ratio on materials. Cold spray offers the potential for AM of titanium parts due to its large deposition rates compared with current AM methods. However, some hurdles are found when spraying titanium by cold spray, in particular the tendency to have high porosity levels and the requirements to use of extreme spray parameters.

Evaluation of the Elder Abuse Prevention and Response Services Program (EAPRS) of Renfrew County

Elder abuse (physical, emotional, sexual, financial abuse, deprivation, neglect) is a pressing social concern. Approximately 10% of seniors in Canada are victims of some form of abuse each year (Department of Justice, 2004). Elder abuse impacts all social, cultural and economic groups. Prevention programs have been put in place to address the underlying causes of abuse, stop it and reduce the prevalence and incidences of abuse. However, the body of research on the effectiveness of elder abuse prevention and the consequences of abuse is sparse.

Improved Automated Tracking of Workouts for Fitness Facilities

Fitness tracking is the process of tracking the fitness-related activity and metrics of a person such as heart rate, distance walked, and consumption of calories. Emerging and specialized wireless sensors and devices also enable the tracking of movements performed during workouts in gyms. This project will help improve the motion tracking experience by reporting workout activities to gym customers, in real-time and in usable ways (via new auditory feedback and enhanced user interfaces) on their Android smart phones.

Robust identification of protected heath information in unstructured data

A large amount of health-related data is available only in unstructured form (“free-form text”). To share this data for secondary purposes, it is necessary to de-identify it to protect against inappropriate disclosure of personal health information (PHI). PARAT Text is Privacy Analytics’ de-identification software for unstructured data. It automatically discovers and marks PHI in a variety of document formats using gazetteers and a bunch of rules. The primary problem of this tool is that it is limited by the knowledge of human experts, gazetteer lists, and lack of contextual knowledge.

Coating Development for Aerospace Parts

We are working on the development of high performance coatings for gas turbines and aerospace parts in collaboration with major aircraft manufacturers.

Religion in the Media: Canada and Brazil

This project will focus on the following research questions:
1) How do the mainstream media (specifically newspapers) in Canada and Brazil portray and represent majority and minority religions in secular context?
2) Are there key areas of controversy in which such portrayals and representations are focused, and do these differ in the two countries?
3) Can common methodological resources and comparable data sets be developed to allow comparison to be undertaken?

Rational design of a red fluorescent protein displaying increased quantum yield

The longer emission wavelengths of red fluorescent proteins (RFPs) make them useful for whole-body imaging because cells are more transparent to red light. However, RFPs are typically less bright than other types of fluorescent proteins that emit at shorter wavelengths due to their lower quantum yields. The goal of this project is to increase the quantum yield of RFPs by rational design. We hypothesized that restricting the conformational flexibility of the RFP chromophore would decrease radiationless decay, thereby resulting in
higher quantum yields.

Sensitizing compounds for cancer-treating viruses find new use in vaccine production

Beyond understanding how oncolytic viruses work, Rozanne and other researchers at the University of Ottawa have studied how these viruses can be enhanced with “viral sensitizers,” small molecules that increase their efficacy. Recently, her research into how viral sensitizers can therapeutically enhance oncolytic viruses has been published in the journal Nature Communications.

Enhancing Prosthetic Socket Performance

For people with lower limb amputations, the interface between the amputated limb and a prosthetic socket is very important. Suspension, or how the socket is held on the limb, is one factor that affects a person’s ability to walk efficiently and safely, movement confidence, limb health, and quality of life. This project will assess, evaluate, and identify area for improvement for new state-of-the-art elevated vacuum suspension systems that could improve functional aspects of socket suspension and also help control limb volume changes that adversely affect socket fit.

Defining Age-Specific Heat Exposure Limits Forworkers: From Laboratory To Field

This project will examine how heat stress develops in young {18-30 years) and older miners {45-65 years) of different levels of fitness when physically demanding mining jobs are made more challenging by increases in air temperature and humidity as well as changes In a worker's hydration status. Further, a field-based study will be conducted to determine to what extent older workers differ in their work patterns and physiological response to work in the heat.
