Deep Neural networks have revolutionized machine learning and in particular computer vision. The revolution was achieved by a combination of big data, graphical processing units and advances in numerical optimization. In this work we propose to extend and develop machine learning techniques, focusing on deep learning methods for public health and safety applications. We will […]

Bioaccessibility of soil sterilants is a limitation in management of sterilant-impacted sites. The term ‘bioaccessibility’ means: what is immediately available, plus that which may become available. Studies have been conducted to examine the bioaccessible fraction of various soil sterilants after different aging periods; however, studies have not been conducted in Alberta. Immobilization technologies such as […]

We are investigating the source of dissolved organic matter (or DOM) – a class of nutrients known to fertilise aquatic ecosystems – in two glacial rivers in Canada (one in the Rockies and one in the Arctic). DOM is a very diverse group of different molecules, and some of these molecules are better food for […]

Northwest Hydraulic Consultants Ltd. (NHC) is often involved in the restoration and design of steep streams. To date when assessing these river channels, NHC has relied upon experimental results conducted with fixed vertical river banks and a series of assumptions have been used to figure out how to make river channels with sloped banks. These […]

As the intensities of urbanization and climate change increase across the Toronto region, there are many benefits pointing to a need for increased investments in our regions urban forests. Urban forests provide co-benefits, services that benefit both humans and the environment, through heat mitigation and mitigation of the “urban heat island”, removing air pollution, sequestering […]

Les marais de Baie-Saint Paul sont de haute valeur environnementale, s’insèrent dans l’économie locale et régionale et dans l’orientation de mise en valeur du patrimoine de la ville. Ces écosystèmes sont le sujet de ce travail qui vise leur étude au niveau physique, historique, géographique et biologique. Quatre grandes questions sont abordées sur ces marais: […]

The Canadian Western Cordillera is a glaciated region within Canada which has seen significant glacial retreat due to recent climatic warming – estimated glacial volume reduction by 70% by 2100. As a result of this glacier retreat, depressions beneath are exposed (known as glacial overdeepenings) and lakes begin to form, dammed by the bedrock or […]

Depuis des milliers d’années, les déplacements des humains ont introduit des espèces exotiques dans des milieux où elles ne se retrouvaient pas naturellement. Une de ces espèces, le nerprun, a été introduite en Amérique du nord vers la fin des années 1800. Elle prend aujourd’hui de plus en plus de place dans nos environnements forestiers, […]

Geophysical electromagnetic techniques are used to scan the Earth’s subsurface and can be used to help find buried materials of economic, environmental and societal importance. They are especially widely used in mineral exploration. DIAS Geophysical is developing a new geophysical electromagnetic system that will be flown under a helicopter that should be more effective than […]

En forêt boréale, les coupes partielles se présentent comme une alternative aux coupes totales pour assurer le compromis entre conservation de la biodiversité et récolte durable de la ressource ligneuse. Bien que les coupes partielles soient des traitements sylvicoles classiques en Europe, leur utilisation demeure marginale et inadaptée aux conditions de la forêt boréale Québécoise. […]

Intensive harvesting practices in British Columbia coastal rain forest, particularly adjacent to streams, result to ecological simplifications that alter the structure, composition and function of ecosystems and may provide limited habitat quality for many vertebrate species. Small mammals are known to respond to these disturbances depending on the harvesting intensity and how often their home […]
