La factorisation matricielle nonnégative (FMN) est une méthode populaire d’analyse de données consistant à exprimer les données comme une combinaison linéaire nonnégative d’un petit nombre de facteurs caractéristiques nonnégatifs. Cela permet de réduire la taille des données, de filtrer le bruit présent dans celles-ci et de mieux les comprendre et les analyser. Cette technique possède […]

The use of new monitoring technologies such as the Motus wildlife tracking system and autonomous recorders currently allow detection of animals and their movements in a variety of ecosystems. Although, the biology of migratory birds in northern latitudes is well understood, there is a lack of information on migration routes, stopovers, and overwinter sites in […]

Bacterial cultures are sometimes added to groundwater to increase the rate of degradation of contaminants. Three cultures that are able to completely biodegrade their primary compound to non-toxic end products in the absence of oxygen have been enriched from contaminated soils. The goal of this project is to demonstrate the efficacy of these cultures in […]

The YWCA aims to evaluate, through partnership with McMaster University, the impact of Good Beginnings, a program providing support for mothers/birthing parents who are vulnerable, precarious, and at-risk for postpartum depression. The program provides service for approximately 70 postpartum people and their babies annually, for a total of 500 people since 2014. During these six […]

Titanium alloys are used to manufacture aerospace components that require high strength at high operating temperatures such fan blades, heat shields and jet engine exhaust cones. Parts that have complex geometries are commonly formed at high temperature (around 900°C) so as to achieve maximum ductility during the forming process. By applying a small oscillating load […]

Multicellular organisms begin as a single cell with instructions encoded by the genome. During development this cell multiplies many times generating an enormous number of cells, each with its own specialized role. For example, developed humans are composed of trillions of cells but our organs and limbs have the right form, location, and function with […]

Additive manufacturing is rapidly employing the Internet of Things and cyber-physical systems to facilitate its reliability and relieve human supervision. However, with 5G network and cloud computing intertwining with the physical machines placed locally, the service is vulnerable to prospective cyberattacks. Various researchers have already stressed the urgent need to ensure the users’ and businesses’ […]

Many Canadians currently do not meet government guidelines for weekly physical activity, particularly among people who identify as women. Media health (mHealth) such as fitness apps and tracking devices can help people to be more physically active. One such resource that has been developed for individuals living in Canada is the ParticipACTION mobile app. However, […]

Nicotine is a highly addictive chemical and smoking is still, to this day, the leading cause of preventable death. Several pharmacological strategies have been approved for smoking cessation and nicotine addiction treatment. However, these strategies are not always effective and lead more often than not to relapse. Hence, new nicotine cessation products and devices are […]

The bacteria living in our gastrointestinal system, the gut microbiome, play a key role in human health and disease. Multiple studies demonstrated altered gut microbiome in patients with constipation or abdominal pain but knowledge of a clear cause-effect relationship or underlying mechanism are lacking. We found previously that microbiota from patients with irritable bowel syndrome […]

Boar taint is an offensive odour in meat from non-castrated male pigs caused by specific chemical compounds present in the fat tissue. Most consumers can detect this offensive odour during the cooking/consumption of pork. Thus, producers and packers need to know about the presence of boar taint in pig tissues to detect tainted meat before […]

The laser powder-bed fusion (L-PBF) process is a novel additive manufacturing (AM) technique used to produce metal objects layer-by-layer using a laser source. Aim of this project is to design an optimized heat exchanger with enhanced heat transfer performance with the advantages offered by additive manufacturing (AM) technology such as complex design and lightweight. The […]
