Cette recherche vise à développer des programmes informatiques qui permettront l’étude des débits de puissance réactive et des procédés de combustion dans les turbines à gaz. La combustion est en soi un processus multi-échelles qui engage une grande variété de phénomènes physiques et chimiques complexes, ainsi qu’une panoplie d’échelles spatiales et temporelles. Étant donné les […]

Les avancées dans la conception d’éoliennes sont considérablement ralenties actuellement par les charges en flexion instables que des rafales peuvent exercer sur les pales. En étudiant la manière dont nagent ou volent les animaux dans des environnements instables, il est possible d’améliorer le rendement des éoliennes qui sont soumises à des rafales. Une recherche biomimétique […]

Les chirurgiens ont l’habitude d’utiliser un électrocautère pour retirer certains tissus indésirables, pour fermer et cautériser de petits vaisseaux qui saignent dans le tissu, ou pour pratiquer une incision chirurgicale. Mais la cautérisation de tissu engendre un panache de fumée qui contient d'éventuels carcinogènes issus de la carbonisation des protéines et du gras. Les tissus […]

La salubrité alimentaire revêt une importance capitale au Canada. Une récente vague d’épidémie de listériose issue d'une usine de transformation de la viande a suscité un intérêt renouvelé pour le contrôle d’agents pathogènes d'origine alimentaire dans les produits à base de viande prêts à manger. L’appareil proposé par cette recherche doit permettre de détecter la […]

Indian student Murtaza Saif made deep connections while honing his skills at UBC As a 4th-year undergraduate student at the Vellore Institute of Technology, Murtaza Saif thought he’d learned a lot already during his degree. So when he found himself examining protein mutations that cause cardiac arrhythmias in a laboratory at the University of British […]

In a typical scenario, a large heterogeneous software system, installed on many different sites and composed of several interacting components, exchanging data with several different protocols, must be updated to correct some defects, add new functionalities, or replace some obsolete components without breaking the system and while keeping its dependability. This research project aims at […]

Currently the implementation of navigation information systems – sometimes called “GPS” or GNSS (Global Navigation Satellite Systems) for convenience – is undergoing some significant transitions.  Additional satellite constellations are being proposed and fielded (Glonass, Galileo, Compass, SBAS) aggressively.  In addition location technology is rapidly being incorporated into the mass-market consumer space thru implementation in cellular […]

Word segmentation in handwritten document is a difficult task because inter-word-spacing (i.e. the space between parts of the same word) is sometimes wider than the intra-word-spacing (i.e. the space between two consecutive words). Many different approaches to segmenting words have been proposed so far. However these segmentation approaches usually use some parameters that are manually […]

Real-time systems are built as sets of components interacting with their environment. In most cases (including robotics, traffic control, manufacturing and industrial applications, etc.), these applications must satisfy "hard" timing constraints. If these constraints are not met, systems decisions (even correctly computed) can lead to catastrophic consequences for goods or lives. The development of real-time […]

Hydrocarbon-based fuels have been the primary source of energy for mankind for centuries. However, during the last century there has been an exponential increase in the utilization of such fuels and the demand for energy is growing continuously. Hydrocarbon fuels are the primary source of greenhouse emissions which are severely affecting the global climate and […]

Since the advent of rail transportation, the integrity of the rail and track conditions play a significant role in ensuring that trains are able to move people safely. Although this work has been hazardous since rail transportation was created, there have been few successful attempts at improving location awareness of approaching trains and the location […]

Canada experienced dramatic increases in the prevalence of overweight and obesity in the past decades as did most countries across the globe. Canadian health care costs associated with excess body weight and its co-morbidities are estimated to be $4.3 billion. Poor nutrition and lack of physical activity are the major modifiable risk factors for overweight. […]
