Ce projet de recherche consiste en l’étude de l’utilisation de poudrette de caoutchouc recyclés traités pour amélioration du comportant des enrobés bitumineux. L’utilisation de la poudrette de caoutchouc devrait permettre une amélioration du comportement à chaud et à froid des enrobés tout en diminuant la quantité de bitume d’apport, ce qui est très intéressant sur le plan environnemental. Des essais de résistance à la fissuration thermique, des essais de modules et des essais de fatigues seront réalisés.
Science-Metrix is a company specializing in bibliometrics, which encompass the measurement of scientific activity using databases on scientific publications and patents. A serious problem in bibliometrics is the ambiguity of the data, especially at the author level. Indeed, one can imagine that in Canada, many scientists are named «J. Smith», but how can we accurately differentiate them? We propose to solve this problem using natural language processing (NLP) and text mining.
Much of the world's high-quality data remains under lock in relational databases. Access is gained through relational query languages. This can suffice for people who are well versed in both SQL and in the schemas of databases. However, anyone who does not know SQL or who is not well versed in the schema is effectively locked out. Keyword search over relational databases was proposed a decade ago to offer an alternative way to query a database. While the general approach has merit, many refinements are needed, before it can be an effective product.
The availability and accuracy of GPS in some environments, such as indoors, is limited. Positioning utilizing radio frequency (RF) signals intended for communication, broadcasting, or networking is an attractive alternative or complement to GPS in such environments. The proposed research will develop novel methods to use RF signals of opportunity (SoO), such as WiFi signals and cellular telephone signals, for accurate and robust positioning in GPS challenged environments. This necessitates an investigation of the effects of RF signal characteristics on positioning performance.
Nowadays the most rewarding aspect of engineering is to create solutions to the needs of society in a natural and resource efficient manner, therefore we must come up with more innovative and resource efficient solutions. One such solution can be a novel, flexible and scalable power-patch, which integrates an inductive coupling, a power conversion and conditioning unit and a super capacitor based energy storage system using a state-of-the-art polymer integration and packaging technology.
Investigating Nano-Media develops and disseminates groundbreaking technological innovations in the field of nanooptics and explores the possibilities of a new nano-material--nano-media--for communication, media and art practices. We deploy a pioneering multi-functional nano-fabric that comprises nano-substrates with embedded functionalities and new advanced fabrication processes. This unique nano-fabric is then further augmented by the processes of ‘nanography’ and ‘nano-photography’.
We study a novel type of optical transistors using metallic nanohole arrays. The transistors operate based on strong coupling between surface plasmon polaritons and excitons via the metallic nanofeatures. One such transistor can act as a control unit, a photo-detector or a modulator and can open innovative practical applications in many fields. The physical structures of the transistors are flexible, light weight and ultrathin, so that they can be integrated in large scale with other types of thin-film optoelectronic components.
This project aims at designing and implementing new interface systems for large-area multitouch displays. The activity will start with building a behavioural model for the analog front-end circuits of a single panel. Then the model will be scaled to simulate multiple touches and complex gestures. At this point, the model will be implemented on an FPGA platform and the higher-level control software and the interfaces with standard operating systems will be developed.
The project will develop a revolutionary, conformable hydrogen storage tank solution for fuel cell electric vehicles. The specific objective of this research collaboration is to develop a hydrogen storage medium that is stable at ambient conditions, has a high gravimetric hydrogen storage capacity and can be packed into a fuel tank for use in vehicles. The research will focus on assessing the feasibility and development of two-dimensional layered nanostructures, such as graphene, as a viable material to store hydrogen.
In concert with Sinclair Interplanetary (SI), we are proposing a MITACS Elevate Postdoctoral Fellowship for Mr. Tom Dzamba under the supervision of Prof. John Enright, a researcher at Ryerson University. In the course of this fellowship, Mr. Dzamba will lead the redevelopment of the SI ST-16 star tracker in order to improve its measurement accuracy by a factor of ten. The ST-16 is a small instrument that allows a spacecraft to make precise measurements of its own orientation. Dr. Enright and Mr.
