Power train electrification is currently one of the best solutions in order to design cleaner vehicles. Nevertheless, the internal combustion engine is still essential to ensure high vehicle autonomy (over 500 km) and fast re-fuel (under 5 minutes). To obtain a commercially-competitive electric vehicle, important progress must still be realized concerning the energy storage and especially the batteries (power density, lifetime, and cost).
Video surveillance is ubiquitous, which has severe implications for an individual's privacy and personal freedom. Consequently there is an increasing interest to design video surveillance systems with built-in privacy protections. This is part of the larger "privacy by design" initiative led by the Office of the Information and Privacy Commissioner of Ontario. This project specifically focuses on event-driven video encryption and decryption. The encrypted footage can only be decrypted and viewed with proper legal authorization.
One of the next frontiers of integrated photonics is surely represented by the challenge of extending the use of optical techniques to nanometer length scales, overcoming the limit imposed by diffraction, which does not allow focusing light on dimensions smaller than roughly half a wavelength. Metallic nanostructures have proven to be an efficient way to "squeeze" light on such dimensions, significantly enhancing the local field at the same time.
The conventional (indirect) georeferencing of remote sensing imagery requires the use of control points that link known positions in the imagery to known positions in map coordinates. The number of control points depends on the amount of distortion in the imagery, method of transformation and desired level of accuracy, but it is often large. Overall, the collection of ground control points is a cumbersome and time-consuming operation, and almost an unrealistic one when it comes to the georeferencing and mosaicking of a set of images acquired from a small unmanned aerial vehicle (UAV).
Successful research in environmental remote sensing relies on multiple-view approaches to data collection. In multi-stage remote sensing, data are collected at different geographic scales. Low-altitude, high-resolution aerial observations bridge the gap between in situ and satellite-based observations. These can be achieved by unmanned aerial vehicles (UAVs), with minimum logistical support and lower operation/maintenance costs than manned aircrafts.
UAVs (also known as drones) are remotely-controlled or autonomous aircrafts without a pilot aboard.
In many clinical laboratory and pathology testing procedures, visual examination of microscopic slides is needed, e.g., to classify disease developments, to detect the interactions of micro-organisms, to assess the effectiveness of drugs, to determine cell viability and proliferation, etc. These tasks can be found in many important clinical applications, including cancer research, hematology, pharmacology, and genetic testing.
Traditionally, these tasks are performed manually by a qualified laboratory technician.
Our research group examines techniques for mitigation of impairments in optical communications links and for increasing the capacity of those links. We address both optical and digital signal processing (DSP) solutions from a systems perspective. Maximizing the capacity of fiber communications is the rally cry for research in optical communi-cations this decade, with focus on 1) high order quadrature amplitude modulation (QAM), and 2) higher baud rates.
Digital technologies are increasingly present in school, in various forms (specialized software, ipad, online work, reverse class ....). In this project, we will focus on the influence of these technologies on mathematics learning. Research can take many forms depending on the interests of the student:experimentation in the classroom of a particular technology,surveys of teachers and / or students, study of programms and textbooks, analysis of online resources ...
Signals outputted from microelectromechanical systems (MEMS) transducers are often very weak, and the sensing interface circuits must exhibit very low noise levels to enable a large dynamic range of detection. Capacitive sensing interfaces exhibit high temperature stability, low power consumption, low noise, and are appropriate to implementations in CMOS. Different methods, such as switched capacitor charge integration and continuous-time current or voltage sensing circuits are potential implementation candidates.
Atrial fibrillation is the most frequent rhythm disorder in humans (nearly 250,000 patients in Canada). It often leads to severe complications such as heart failure and stroke. Diagnosis of this arrhythmia is mainly performed through the inspection of electrical signal recordings (electrograms and electrocardiograms).
