Mitacs-Accelerate interns help navigate the way to revolutionary positioning software

But GPS has one major drawback which limits its use – it doesn’t work accurately indoors.  Because it relies on signals from satellites, accuracy is also compromised when trying to navigate between tall buildings in urban areas, or under dense foliage.

Calgary-based Trusted Positioning Inc. set out to change this by developing software that would allow for accurate and continuous positioning of a device in any location, be it inside, underground, or in the heart of a dense urban city.

Dynamic mathematical modeling for control of film gauge for Tedlar® film casting

The objective of the proposed research project is to develop a mathematical model that can be used to predict, monitor and control the thickness profile of extruded Tedlar® film, particularly during product transitions and batch switches.  Development of this model will require a detailed understanding of the extrusion and film casting process, as well as identification of key polymer and process parameters that influence film gauge.  Existing and new process data from grade and batch changes will be collected and used to explore the influence of polymer properties and process conditions on

Fighting fires before they start

Parsons Brinckerhoff Halsall Inc, a consulting engineering firm in Toronto that specializes in vertical building construction, recognized this incredible risk to its clients and reached out to the Mitacs-Accelerate program to find the expertise it needed to resolve it.  “Not a lot of people in structural engineering actually devote their careers to fire research,” reported Michael Buckley, Vice President at Halsall, which is why he jumped on the opportunity to engage with a graduate student at Queen’s University through Mitacs-Accelerate.

Software for prediction of postoperative atrial fibrillation following bypass surgery

The problem of accurately predicting the onset of sustained postoperative atrial fibrillation (AF) in patients undergoing coronary artery bypass grafting (CABG) remains open. Investigators have reported many clinical indices currently associated with postoperative AF following CABG. Contemporary machine learning techniques are well-suited to recognizing underlying trends in 'training' data consisting of several labeled examples, and to using the results to classify new unlabeled data with remarkable sensitivity and specificity.

Intern innovation drives business forward

Since the introduction of mass-production in the automobile industry, efficiency and innovation have been of upmost importance for companies wishing to be on the cutting-edge in this highly competitive business.  Aurora, Ontario-based automotive parts supplier Van-Rob Kirchhoff Automotive has found their competitive advantage in the Mitacs-Accelerate program.

Sensor fusion for robust pose tracking using a combined accelerometer-magnetometer-gyroscope device

High-accuracy optical and electromagnetic trackers are commonly used for image-guided interventions for tracking the position and orientation (pose) of surgical tools and target objets. In certain applications these tracking devices could be replaced by small, low-cost inertial measurement units (IMU), which contains integrated accelerometer-magnetometer-gyroscope sensors. Typical size of the sensor is a few centimeters by a few centimeters and it costs about $150. This allows new applications that have not be possible to implement with optical or electromagnetic sensors.

Contour interpolation in medical imaging

Planning of medical procedures, such as radiation therapy or minimally invasive interventions, almost always require delineation of organs and other important structures by closed curves. Most frequently this is performed manually, by drawing contours around the objects on several two-dimensional cross-sectional images.

Visualization of deformation fields in medical imaging

Image registration methods are often used in image-guided medical interventions to determine dislocation of the target organ. Advanced registration methods can determine not just a rigid transformation, but also organ deformations. Performance assessment of deformable image registration algorithms requires visualization of the resulting deformation fields, by means of colored image slices, isolines, arrows, deformed grids, etc.

A Canadian science adventure

The third-year electronics and communications engineering student from the Indian School of Mines will be contributing to more energy efficient heating and air conditioning systems in commercial buildings. The goal of this Mitacs Globalink project will be to implement a wireless sensor network of devices which will communicate with each other to monitor environment conditions such as temperature and pressure, turning on or going to sleep on-command.

Soaring towards medical breakthroughs

Leonam is nearing completion of his undergraduate studies at the Fluminense Federal Institute with a passion for all things “engineering”. Having completed engineering projects to assist in remote monitoring of the Paraiba do Sul River as well as testing equipment for an Unmanned Aerial Vehicle, Leonam set his sights on Canada for his next research adventure, this one in the life sciences through Mitacs Globalink.  While at Queen’s University in Kingston, Ontario, Leonam will assist Dr.
