Evolution of communication technology is pushing the limits beyond those of conventional radio frequency and millimeter-wave devices. A key trend in this evolution is miniaturization and ultrahigh density integration of radio/microwave frequency devices. Micro-electromechanical systems (MEMS) technology provides the opportunity to develop micro-scale RF devices and satisfy the market demand. This technology has made it […]

Our research aims at developing highly interactive and inter-operative applications for use in complex simulation environments. Its goals are to develop a suite of modeling, simulation, and analysis tools for: (1) the planning and management of construction projects throughout their life phases from conception to operation, (2) the training of construction personnel, and (3) the […]

The project’s aims are to conduct research on geological carbon storage from the perspective of dynamic analysis and process systems engineering, looking in particular at the dynamics between the wellhead and the CO2 storage reservoir. The main objective is to achieve closed loop operation and management of the reservoir with respect to CO2 sequestration and […]

Fixed-rate coding for cooperative wireless networks with decode-and-forward (DF) relay processing has received much attention. Yet, only a fairly narrow body of research exists on rateless coded DF relaying networks. Little is known about how the performances and complexity implications of fixed-rate and rateless coded systems compare. Meanwhile, such comparisons play a vital role in […]

The stochastic resonance (SR) is a phenomenon discovered recently in some nonlinear systems where addition of a certain amount of noise can, somewhat paradoxically, enhance its performance. It has found applications in biological sensory systems [1] such as visual, auditory systems, and tactile system as well as engineering applications such as ac-driven Schmitt triggers, and […]

Food safety is of paramount importance to Canada. Recent episode of Listeria out-break in a meat processing plant has created renewed interest in monitoring of food borne pathogens in ready-to-eat (RTE) meat products. The proposed device is aimed to detect Listeria monocytogenes in food samples within a few hours. This device integrates the microfluidics and […]

This project involves several researchers in the Multimedia Communications Lab at SFU, and isaimed at developing a prototype system for binocular stereoscopic eye tracking. The systemwill consist of eyeglasses worn by the subject, two infrared eye cameras (one for each eye) and astereo imaging device. In addition to conventional gaze direction estimation, this would requireestimating […]

In this project, we aim to develop a mathematical model and perform numerical simulations for gravity-driven fingering instabilities that occur during the flow of groundwater in soils and aquifers.  Fingers form in response to gravitational forces that derive from the difference in density between invading water and displaced air.  These forces can destabilize an otherwise […]

We are conducting an exciting project on building tools for managing personal social networks.  You have a lot of friends, communicating with you in a few online social networks, such as Facebook, LinkedIn, and Twitter, as well as some traditional channels, such as emails, phone calls, and online messages.  How to manage your contacts in […]

Computationally hard search and optimization problems are ubiquitous in science, engineering andbusiness. Examples include drug design, protein folding, phylogeny reconstruction, hardware andsoftware design, test generation and verification, planning, timetabling, scheduling and on and on. Inrare cases, practical application-specific software exists, but most often development of successfulmethods requires hiring specialists, and often significant time and expense, […]

We are interested in understanding the power and limitations of families of algorithms for solving combinatorial search problems, in particular those whose decision versions are NP-complete.   In some application areas involving such problems, the state of the art involves representing a problem instance as a formula of propositional logic (or a natural extension, typical examples […]
