Component-based Detection for 3D Objects

This project in collaboration with Lockheed Martin Canada and University Laval is on aerial surveillance. The goal is to develop and implement algorithms for the automatic object detection using electro-optics data to be used in conjunction with standard operation with the aim of enhancing the speed and accuracy of the regular detection of objects from aerial images. The challenge is to recognize 3D objects in real-world 2D imagery.

Computational Models for the Analysis of Aircraft Structures

Viking Aerospace Ltd., a company providing engineering support services for Unmanned Aircraft Systems (UAS), is currently seeking approval of a Supplemental Type Certificate (STC) for the DHC-3 Turboprop conversion kit. This conversion kit has provisions for a nose fuel tank. A separate STC is desired for the addition of this tank. In order to gain approval for the fuel tank STC, compliance must be shown to FAR 23 regulations.

Mathematical Modelling of Planing Hull Motions in Waves

In the marine and offshore industry, the safety of small vessels such as life boats and fast rescue crafts is a critical issue to designers, operators and regulation bodies. It concerns not only the reliable design, but also the safe training and operation. Accurate prediction of small vessel motions in waves is essential to the design process. On the training side, it is important to avoid exposing trainees to dangerous and extreme conditions. The ideal solution is high-fidelity simulation which also requires accurate prediction of vessel motion.

Protection Strategies for Subsea Wellheads in Iceberg Environments

The design of subsea infrastructure on the Grand Banks and, potentially, Labrador Sea must address the potential interaction with freely floating and gouging icebergs. Current practice is to protect the subsea infrastructure, such as conductors, wellheads and production trees, within massive excavations known as glory holes. For marginal fields or satellite wells, considerations of capital cost, construction cost and risk for developing the reservoir and protecting the assets may not be sufficient for project sanction.

Form & Language for the Astronomical Study of Hydrogen

This project undertakes the visualization of astronomical data in 3D enabling us to study phenomena such as expanding gas shells and rotating galaxies. We will develop a 3D mathematical model of astronomical observational data, apply this model to the data and display the data utilizing the technologies available through the Virtual Reality Centre.

Implementation of 3D Grid Movement Algorithms

This project involves the development and integration of mesh movement algorithms with the analysis software at Bombardier Aerospace. The algorithms are used to conform the volume mesh to the geometry as it evolves in an optimization cycle or in aero-elasticity analyses.

Study of Connection Times for Air Canada

The objective of the internship is to develop better thresholds for minimum connection times between flights. These thresholds must be large enough to reduce the risk of passengers missing their connecting flights due to flight delays. On the other hand, lengthier connection times lead to increased costs as planes and crews must wait longer between flights. The best compromises will be found by using historical data on flight delays to evaluate the effect of varying thresholds on the plane and crew costs using optimization models.

Improved Sizing of Defects Using Ultrasonic Phased Arrays

Olympus NDT is a world-leading manufacturer of innovative, nondestructive testing instruments that are used in industrial and research applications ranging from aerospace, energy and automotive to consumer products. The primary focus of this internship research is to sharpen images of cracks and imperfections that have developed in oil pipelines to within + 0.5mm using an ultrasonic phased array. Ultrasonic phased arrays are a relatively new technology for industrial testing and currently can size defects and cracks to within + 2mm.

Wave Diffraction of Floating Structures in Partially Frozen Seas

The objective of the proposed project is to develop a mathematical model to compute the wave diffraction force on a floating structure partially frozen or surrounded by an ice sheet. The horizontal and vertical forces on the cylinder and bending stress in the ice plate will be computed. The results will be compared with those by decoupled solutions. The research results will improve the understanding of the coupled wave-ice-structure interaction and will lay a foundation for the development of a comprehensive simulator to simulate floating structures in harsh environments.

Mathematical Modelling of Small Craft Motion

Simulation training is widely used in the aircraft industry to train pilots to operate aircraft. Likewise, ship bridge simulators are used to train the crews of large vessels. The efficacy of this type of training is recognized by international standards and is often required by regulations. A new application of simulation training technology is being developed by Virtual Marine Technology in co-operation with researchers at Memorial University. Specifically, they have developed immersive training simulators for small vessels such as lifeboats and fast rescue craft.
