Le Canada figure parmi les plus grands consommateurs d’énergie par habitant au monde. En 2009, les Canadiens ont dépensé environ 11 p. 100 du produit intérieur brut (PIB) du Canada (près de 152 milliards de dollars) en énergie pour chauffer et climatiser les habitations et les bureaux, faire fonctionner les véhicules et les appareils ménagers, […]

Emissions from the combustion of fossil fuels in the Eastern US, has long been identified to acidify Nova Scotia lakes. However, due to a reduction in the use of high-sulphur fossil fuels, lakes are beginning to recover which is resulting in chemical and biological changes. In Nova Scotia, lakes are often relied on to provide […]

Emissions control is an important part of any environmental policy. However, in dense urban environments and other locations, it is important to deal with sound as well. To ensure effective pollutant mitigation while also ensuring minimal acoustic disturbance, it is necessary to look at computer models that look at these factors simultaneously. This work will […]

This project will refine an existent technology developed by us for freeze-drying biological and medical solutions to produce powders. Freeze-dried bio-medical powders are used in pharmaceuticals as well as for food. The technology we will refine in this project is called atmospheric spray freeze drying (ASFD) and has the potential to be faster and more […]

In this project an acoustic network is studied to reduce the data transmission requirement in a multi-static sonar network. A cross-layer communication architecture is proposed to optimize the acoustic network performance. Using this technique, the network will be informed with the physical conditions of the link to optimize the overall reliability of the data transfer. […]

Powder metallurgy uses metal powders to produce parts of varying complexity. The processes can generally be divided in two big steps. The first is to form the powder into the required shape. This is generally done by pressing or molding the powder. The second step is to consolidate the powder into a solid piece of […]

Traditional fleet management systems suffer from zone-based aggregation. i.e. they use aggregate zone-level road and terrain characteristics to estimate trip performance indicators. In addition, most of these systems require intermediate ad-hoc staging tables to generate trip performance reports. To address these limitations, this research aims at developing a segment-based fleet management system for near real-time […]

Le composite bois-polymère (CBP) est un matériau émergent fait de bois et de plastique. Le plastique est habituellement d’origine fossile. Le projet de recherche propose d’explorer différentes technologies visant à augmenter la proportion de matière biosourcée pour former des CBP écologiques. Ces technologies permettront aux partenaires oeuvrant dans le domaine de la transformation des produits […]

In this research project, the separator of rechargeable hybrid aqueous batteries (REHABs) is mechanically strengthened with graphene oxide derivatives. ReHABs comprise of a lithium intercalation cathode, zinc anode and an aqueous electrolyte. One of the problems with current ReHABs is the zinc dendritic growth and propagation from the anode, which significantly reduces its operating lifetime. […]

Bio-heap-leaching is a hydrometallurgical process used to process low grade chalcopyrite ore as the cost of alternative routes of processing and refining are not economically viable. The limitation however of the heap leaching process is the long time it takes to leach the metal and the low total recovery that can be achieved. As heap […]

The amount of emissions to the atmosphere is currently an important environmental concern as policy makers and Heads of State are starting to demonstrate a strong interest in energy efficient transportation, in particular energy efficient aircraft. The task of energy optimization is typically left to a flight management system (FMS). However, many smaller commercial aircraft, […]

Raman spectroscopy is a compound identification technique that can be used for real-time identification of cancerous tissues during surgery. The development and clinical translation of an intraoperative surgical-guidance instrument based on this technique is the main objective of ODS Medical, a Canadian startup. However, Raman signals are intrinsically very weak thereby requiring the measurements to […]
