Bohemian Matrices and Applications

“Bohemian matrices and applications” is a new and growing field in computational mathematics invented at Western University. The name “Bohemian” is a mnemonic for “Bounded Height Matrix of Integers”, which means that the entries of these matrices are drawn from a small set of numbers, such as {-1, 0, 1}. The original motivation for starting this field was to test software: we have found bugs in Matlab (a computer program which is widely-used by engineers and mathematicians), notably in the eigenvalue routine. However, as this field progressed, we have found many other applications of Bohemian matrices, such as (but not limited to) vibration analysis, compressed sensing, and optimization problems. The proposed research project (together with two of the top computer algebra research centers in the world) is to establish some foundational technical results for different families of Bohemian matrices.

Analyse biologique de différentes espèces de poissons d’eau douce d’intérêt pour la diversification de l’industrie piscicole Québécoise.

L’aquaculture est l’industrie agroalimentaires mondiales avec la plus forte croissance. Au Québec pourtant, la production piscicole ne bénéficie pas de cette croissance. L’industrie piscicole québécoise n’est pas très diversifiée et produit principalement de l’omble de fontaine, de la truite arc-en-ciel et de l’omble chevalier. Le nombre restreint d’espèce et la réglementation rigoureuse rend cette industrie plutôt vulnérable. Le projet vise identifier les espèces d’eau douce qui ne sont pas produites actuellement de façon commerciale au Québec, mais qui auraient une valeur marchande intéressante sur le marché de la table. Le projet permettra de (1) sélectionner et pondérer des critères, tant biologiques, physico-chimiques, techniques, financiers que réglementaires, servant à l’évaluation du potentiel d’élevage et de domestication de poissons, (2) de sélectionner les espèces à considérer pour le développement de l’aquaculture, (3) d’évaluer la préfaisabilité de projets d’élevage grâce à l’élaboration de modèles technico-économiques et (4) d’identifier les avenues de recherche maximisant la rentabilité commerciale.

Partnership Capacity in Australian Community Sport

Community Sport Organizations (CSOs) exist to provide opportunities for sport participation for youth and adults in many countries around the world. These nonprofit, voluntary organizations face many challenges in an increasingly complex environment due to their diverse stakeholders, scarce resources, volunteer turnover among other issues (Allison, 2001; Hoye & Cuskelly, 2007). Interorganizational partnerships have been identified as a central dimension influencing the overall organizational capacity of CSOs and the ability of these organizations to achieve their missions (Misener & Doherty, 2013; Doherty, Misener, & Cuskelly, 2014). This study will research partnership capacity within Australian CSOs. The particular objectives will be:

(1) to explore the type, frequency, and key motives for partnerships in the community sport sector;
(2) to identify the key capacities required to develop and manage effective partnerships;
(3) to understand the outcomes of community sport partnerships in the Australian context.

We anticipate that this study will result in theoretical development related to partnership management as well as cross-cultural comparison in addition academic manuscripts and technical reports for participating CSOs will be developed at the end of the study. This will also serve as a foundation for my future dissertation studies related to building capacity in youth sport organizations.

The effects of One to Zero Technique on neural function, health and well-being

The one-to-Zero (OTZ) Tension Adjustment is a chiropractic technique which corrects articular dysfunction of the articulation between the skull and the top vertebrae of the neck, also called the atlas. The goal of this study is to determine whether correcting dysfunction using OTZ affects brain processes and overall health and well-being. Participants will complete questionnaires relating to health and well-being before and after treatment. Researchers will also measure neck, arm and leg muscle strength, heart rate variability, and awareness of head position in 3D space, twice before treatment begins and at the completion of treatment. This study will help researchers to understand more about how altered sensory input from the neck muscles impacts overall health and performance. It will help Dr. McCord’s practice by providing evidence of the impact of OTZ on health.

Energy Selection Functions: Evaluating Polar Bear Movement Energetics

The energetic cost of traversing the environment is a fundamental component of an animal’s energetic balance and subsequently, their body condition. Polar bears (Ursus maritimus) occupy dynamic sea ice habitats, which result in spatiotemporal variation in their energetic costs of movement. My objective is to evaluate the role of energetic balance in governing polar bear movement decisions. Most animal movement models ignore the role of energetics when evaluating space-use and movement patterns. I will modify a popular model to include estimates of energy expenditure/gain, resulting in variant models referred to as energy selection functions (ESFs). I will calculate energy expenditure from remotely sensed ice data and estimates of polar bear metabolic rates, and energy gains as a function of prey densities. This will form an energy landscape, onto which I will overlay bear GPS data to evaluate movement in relation to the energetic costs/gains of each GPS relocation path. ESFs will be the first animal movement models to consider energetics as a determining factor in animal movement decisions.

Analyse et prévision des prix du bois d’œuvre

Les prix figurent parmi les décisions importantes à prendre par les responsables des ventes. En particulier pour les entreprises du bois d’œuvre, les responsables de ventes se fient aux estimations des prix, basées sur le jugement d’experts, fournies hebdomadairement par le Conseil de l’Industrie Forestière du Québec (CIFQ). La génération hebdomadaire de ces estimations de prix nécessite beaucoup d’effort et ne représente pas une procédure viable à long terme. De plus, le CIFQ dispose d’un grand volume de données qui doivent être prises en considération pour générer des prévisions de prix. Ce projet vise à fournir aux experts du CIFQ un outil qui permet de valoriser les données dont ils disposent et de faire ressortir toutes les informations pertinentes permettant de prévoir de façon

Device-free indoor activity detection and localization using Wifi signals

Creating smart indoor environments that detect and understand human daily life activities is attracting significant amount of attention, due to their huge potential impact on context-aware technologies. Aerial Technologies, our partner organization, is developing products that provide device-free indoor localization and activity recognition Wi-Fi signals generated by off-the-shelf Wi-Fi enabled devices. This project will use state of the art machine learning and time-series analysis algorithms to improve the detection and classification capabilities of these systems.

A Novel Bone Anabolic Treatment in a Mouse Model of Osteogenesis Imperfecta

Osteogenesis imperfecta (OI) is a heritable disorder that causes bone fractures. The drugs that are used at present help to decrease the number of fractures by about half, but most people with OI have many fractures despite receiving currently available treatments. Mesentech Inc has developed a new drug that has shown a strong effect on bone formation in rats. In this project, we will test the effect of this drug in a mouse model of OI. The new drug will be injected three times per week during a period of four weeks and the effect on bone strength will be assessed. We expect that the new drug will increase bone formation activity and make bones stronger in OI mice. This will open a potential new treatment avenue for patients with OI.

Design and manufacturing of a plastic anchor using a chemical product acting as a time-dependent expansion mechanism

The objective of this project is to investigate the feasibility of a novel anchor fixation device for which the anchoring mechanisms is prompted by the expansion and polymerization of a polymeric material. Accordingly, an innovative solution inspired from the self-healing polymer concept is proposed for sufficient expansion and fixation to wall panels for masonry and commercial buildings of North America. The anchor must harden in less than 30 seconds after expansion and when exposed to air. In addition, the chemical component must have a shelf-life of at least 36 months. In association with Polytechnique Montréal, Cobra Fixations target to design, manufacture and test the tailored wall anchor. To achieve this goal, the first and foremost is to perform a comprehensive literature review on plastic wall anchors existing in the construction market and then self-healing materials, which provide autonomic repairing mechanisms, used to various engineering systems.

Effects of a powered and automated cargo management system on the biomechanical variables of workers during ladder lifting tasks: A pilot study

Portable ladders are used by workers in industries such as construction, electrical, and telecommunications. A new powered and automated cargo management system, the RazerLift, has been designed to assist workers during portable ladder lifting tasks. The objective of this study is to investigate whether this system improves the biomechanical variables of workers during ladder lifting tasks. Each participant will perform a ladder lifting task using a powered and automated cargo management system. The biomechanical variables will be calculated during the ladder lifting tasks. Specialized software will be used to calculate these biomechanical variables. In addition, paper-based questionnaires will be administered to the participants after conducting the lifting tasks to determine their acceptance and the usability of the system. The partner organization will benefit by having its product validated for use by its clients. The feedback will also help the partner organization to scale up its product by marketing it to a wider range of users and/or industries.
