Some social mammals present a group dynamic related to spatially and temporally variable environments described as fission-fusion dynamics. This dynamics is defined as the temporal division of a group into sub-groups varying in size and composition, and is thought to occur through social regulation to improve foraging efficiency. Nevertheless, the influential factors in that dynamics […]

Les forêts tropicales sont de plus en plus menacées par la déforestation, les incendies et les perturbations climatiques. Afin de surveiller la biodiversité et de prévoir les tendances spécifiques à chaque espèce, les chercheurs ont commencé à utiliser des technologies aériennes sans pilote (i.e. drones) pour identifier les espèces et cartographier la forêt. Cependant, les […]

Current commercially available dental resin composites use the monomer BisGMA that uses a toxic bisphenol A (BPA) as the starting material, causing potential environmental and health problems. We aim at replacing BPA with bile acids, natural compounds in the new synthesis of new dental monomers. We are also making new inorganic fillers that provide the […]

Organic electrochemical transistors (OECTs) are emerging as important rival in the field of organic bioelectronics. The core of OECT devices is an organic conducting polymer channel, defined by source and drain electrodes, ionically connected to the gate electrode via an electrolyte solution. Prior to the application of gate voltage (Vgs) the source-drain current measured upon […]

In the 1920s, many companies popularized the use of aluminum discs coated with nitrocellulose lacquer for instantaneous audio disc recording. In particular, the American company Presto produced a range of discs, cutting lathes, cutter-heads and other equipment, all of which served to encourage home audio recording, as well as the unexpected and experimental use of […]

Among the different sub-systems in an aircraft, the environmental control system is the one responsible for the control of temperature, pressure and humidity in the cabin and is crucial to passenger comfort. This system has around 40 components including heat exchangers, compressors, and turbines. Recirculation at different levels complexifies the modeling and simulation of such […]

PPLCONNECT believes that users should be able to continue their conversations cross-device. Today the user is forced to have multiple identities for the various types of calling services, like VoIP, their Landline and their mobile number. Using the cloud to build a virtual Smartphone PPLCONNECT helps centralize for the user, one place to access and […]

The project consists in devising a method to quantitatively describe textural features of ores; these features may include mineral composition, grain size and shape, spatial distribution, etc. Equally important is relating these features to the performance observed when processing the ores. The foreseen deliverable is a tool to predict ore processing performance. The scale of […]

Pharmaceutical companies are required to perform stability testing of their drug products by regulation. A drug product that succeeds on stability testing means that its identity, potency, and purity remain within pre-established limits over its shelf life. Nowadays, drug products are more frequently reformulated in response to a highly competitive market, new research discoveries and […]

Ce projet analyse les communautés de femmes qui se forment dans les Manzanas del cuidado qui sont des « espaces de concentration de services qui rassemblent et articulent des services, des programmes ou des activités dirigés au care, autant pour celles et ceux qui ont besoin de soin (cuidada.os) que celles et ceux qui le […]

Chaque année, environ 10% des canadiens autonomes (65 ans et +) subissent des blessures mineures (fractures, entorses) conduisant à un déclin fonctionnel (pertes de mobilité et d’autonomie). 65% d’entre eux auront recours aux urgences après leurs blessures et 18% auront un déclin fonctionnel 3 à 6 mois après leurs consultations aux urgences et seront dans […]

Deicing is a complex process involving many actors including pilots, air traffic controllers and the deicing crew. In this context, communication mistakes can easily happen but can also have terrible consequences. The goal of the research project is to identify high risk areas of communication for aircraft ground deicing. Analyze of the voice interaction between […]
