Compact Broadband Antenna Design

In broadband communication systems, one of the key issues is the design of a compact antenna while providing wideband characteristic over the whole operating band. This project focuses on novel antenna designs with appealing features of very wide bandwidth or multi-band performance, simple structure, omnidirectional radiation pattern and ease of fabrication. The objective of this project include wide frequency band, good VSWR, compact dimension and low power rating. This project requires extensive experimental work and numerical electromagnetic (EM) simulations.

A Human-Friendly Magneto-Rheological –Based Robot

The objective of the proposed research is the development of a new type of industrial robots that are capable of safely interacting with humans. These new robots are expected to transform industrial automation by providing a robotic platform that allows integration of man and machine in a safe and functional manner. Our main challenges are to meet the strictest safety standards using technologies that render industrial robots qualified for entering human workspaces and at the same time provide a cost effective and intuitive means of interaction with the robots.

Pure Optical Blending Technology for VisSim

High resolution, large area displays are currently realized by tiling multiple projectors. Seamless transition between adjacent projecting areas is achieved by electronics blending, which is unable to correct artifacts in the transition regions especially for dark scenes. We propose a feasibility study of using optical blending techniques as potential solutions to the above problem. We plan to develop numerical simulation methods and MTF measurement techniques to quantitatively design and evaluate the blend quality.

Toward Automating Pattern-based Application Integration

Integration is a core IT operation, and is aided by a number of available best]practice techniques for integration (integration patterns). However the application of these patterns has little to no automated support. They are applied by consultants on a per-customer basis, making it an expensive and time consuming task. A computer science student from the University of Toronto will work with IBM at their Toronto Center for Advanced Studies on building a set of heuristics to aid the understanding and the application of integration patterns.

Software Diversity Measurement

Given a landscape of computer software that is made up of very few platforms and operating system types, attacks on software can often come in the form of comparing differences between instances or revisions of software. Diversifying software is an effective technique to mitigate these kinds of attacks. Software diversification is a means to generate program instances with varying program structure to an original program while still preserving functionality of the original code. Just as living, biological entities have a different make]up, so can software be diverse.

Simulation of Network Attacks, Part II

The rapid propagation of Internet into nearly every aspect of our daily life together with the increase in volume and sophistication of network attacks puts a special emphasis on the security of the network systems. Currently, security modeling and simulation is one of the widely acknowledged methods for network security evaluation. However, in spite of its fundamental role, the information and communication security domain still lacks the sound and comprehensive tools for assessment of network system state.

Multiple Hypothesis Tracker (MHT) for Multitarget Tracking

In this work, a real-time feasible Multiple Hypothesis Tracker will be developed for multiple targets tracking. A computationally feasible approximated version of MHT will be compared against the robabilistic Data Association (PDA) based Tracker as well as multi-frame assignment based multitarget tracker. Intensive testing will also be performed in order to determine the performance, complexity, and resource usage of proposed and existing and proposed algorithms.

Sensor web adaptation to geotechnical sensor networks

This project investigates the use of adaptive sensor web systems in supporting a geotechnical sensor called the ShapeAccelArray. ShapeAccelArrays measure the movement of earth by placing a long (up to 100m long) thin (27mm diameter) tube containing special micromechanical gravity sensors inside a drilled hole in the earth. These holes are typically in earthen slopes used in many places to support roadways, bridges, dams and other civil structures.

On-Demand Expansion of eBusiness Services to the Cloud

The project will help eBusiness service providers to react faster and more economically to changing demands on their IT services. The goal is to develop automated techniques to utilize off-site computing resources that are offered on the Internet (so-called cloud computing resources), whenever there is a particularly high demand on the company internal computing infrastructure. The cloud computing resources can be used to temporarily augment the internal infrastructure.

Design, implementation and evaluation of the prototype for power management in data centres

The project is intended to develop, implement and evaluate a power management solution applicable to data centres. The solution must not require installation of custom software components onto the individual servers. This constraint goes against current solutions which install bespoke software on the servers for the power management solution to function effectively. The solution will have to provide perceivable power savings without loss in the service quality©\two conficting goals. Innovative algorithms and policies must therefore, be developed.
