Tailoring Microencapsulation Strategies for New Applications

The application of microencapsulation technology provides for separation between reactives and curatives, allowing 2-part systems such as adhesives, to be formulated and applied with the inherent stability of a 1-part system. Release and subsequent curing can be controlled to occur “on demand”, for example upon the mechanical fastening of a screw, which results in capsule rupture. This is often highly dependent on the careful design of a specific system.

Control of a Self-Organizing Network of Quadrotor Vehicles Interacting with Real-Time Acoustic Signals

Networks are pervasive in our world. From migrating birds flying in formation, to social groups, wireless networks, world-wide web, the examples are endless. Migrating birds, such as the Canada goose, are a good example of a network between agents where information is communicated based on real-time musical (acoustic) signals. Inspired by this example, the research problem being addressed in this proposal is the real-time autonomous response of a network of quadrotors to acoustic inputs in a choreographic performance.

Automated optimization of robotic tasks and transitions using graph-based approaches

In recent years, machining with robots has become a trend in the manufacturing industry. The concept offers an economical solution for medium to low accuracy machining applications. However, due to the complexity of the robot kinematics, planning for these paths is challenging. Jabez Technologies has developed a semi-graphical approach that can program large robot-paths. This approach has been very well received by the industry and has proven to be extremely robust in practice. However, this approach is semi-automatic and cannot work without user input.

Efficient design of quiet turbomachinery stages with a unique coupling method

Most current propulsion and ventilation systems still suffer from poor efficiency, noise issues and too high emission levels. Little efficiency gain could yield significant reduction of energy waste, noise pollution, gas consumption and pollutant emission. Moreover a lot of the large rotating facilities do not meet their target performances and suffer from early degradation and fatigue issues causing some significant cost increase and losses to the companies producing them.

Aerodynamic Noise of High-Lift Devices

The proposed project studies the noise sources of airplane high-lift devices (HLD) that are responsible for most of the aircraft noise at approach. The latter in turn creates noise nuisances that create health issues to populations close to large urban airports. Two approaches are followed. A state-of-the art simulation that predicts most of the turbulent structures that generate the HLD noise will be performed and will serve as a reference to the development of analytical models of the HLD noise that will be integrated in a  unique software by the partner.

Improved Tactile Sensors for Biomedical Applications

The Institute of Biomedical Engineering at UNB is at the frontier of myoelectric signal acquisition and interpretation in patients with prosthetic devices. A particular challenge is understanding the effect of surface contact pressure on voltage measurements at the skin-electrode interface. Smart Skin Technologies (SST) is a New Brunswick company developing multi-touch pressure sensors aimed at several markets including smart-phones, sports training and industrial quality assurance.

Field Tests of Seed Openers and Data Analysis

Openers are the major components of a seeder, and the performance of openers affects the performance of the seeding operation and crop yield. Atom-Jet Industries manufactures hoe type openers, the most popular openers in Western Canada. For the past 20 years, Atom-Jet has been continuously improving the performance of their openers to provide farmers with high precision and long lasting openers. In the proposed project, field tests will be conducted to evaluate the performance of Atom-Jet openers, and to compare the performance of Atom-Jet openers with other openers on the market.

Development of a simple and inexpensive method to quantify surface contamination on metals

Metallic parts are used in combination with oil or grease in many applicaitons, for example in car engines or hinges. To re-use them, the surface of the metal needs to be cleaned. Current technology makes use of solvents to remove the contamination. Although very effective, this method is polluting. Our industry partner (Walter Surface Technologies) has developed a new technology with very low environmental impact. They wish to test the effectiveness of their technology by measuring the amount of contaminant left on metal surfaces after cleaning with their products.
