Students use new lab to test electrical and cybersecurity systems The BC Institute of Technology

IEC 61850 standard for SA systems application and the investigation of operating scenarios—it can be used to study network topology, test reliability of process bus for protection schemes, and review fundamental concepts such as interoperability and cybersecurity. Cybersecurity intrusions can be simulated from multiple access points, with users able to initiate attacks, eavesdrop, playback, and spoof, as well as inject malformed packets into internal and external streams. APEGBC members, BCIT: Dr. Hassan Farhangi, P.Eng., Dr. Heydarali (Ali) Palizban, P.Eng.; LEX Engineering Ltd.: Gagan Deep, P.Eng.

Smart Microgrid Applied Research Team designed and implemented an IEC (International Electrotechnical Commission) 61850-compliant substation automation (SA) and process bus demonstration laboratory. The lab is used to train BCIT students in applied electrical and cybersecurity engineering. Using real-time digital simulators and commercially available equipment, the lab enables students to examine automation, networking applications and flexibility of power system topologies and protection schemes. The lab supports study of the

Device provides environmentally friendly high-pressure cleaning

The machine uses a non-pressurized 90-lb (413-kg) hopper while operating at a pressure of 60–150 psi (41–1,034 kPa), optimal for cleaning marine and industrial equipment. Upon surface impact, the melting ice traps debris and fibre particles. This allows for safer asbestos removal, with aerial contaminants being five times lower than the regulated allowable maximum.

Developed by The Coulson Group of Companies, Port Alberni, BC, the IceStorm 90 is a high-quality, environmentally friendly, industrial precision-cleaning ice blaster. The device uses only 10 percent of the water traditionally used in pressure washing, and uses neither environmentally harmful abrasives nor expensive blasting media such as dry ice and sand.

Novel system compresses motion-capture data

rate control, bit allocation, and motion- adaptive filtering to maximize data quality for a given bit budget. In addition, error- concealment strategies are developed for recovering from errors or packet loss when data are transmitted over unreliable links.

With advancements in three-dimensional measurement, motion-capture data are extending beyond animation and gaming to penetrate new application areas relating to rehabilitation, remote interaction, virtual reality and augmented reality. To help further adoption of these technologies and enable future applications, researchers at the Simon Fraser University Multimedia Communications Laboratory have developed a novel system for motion- capture data compression. The new motion-capture codec incorporates advanced features for

Unlike most other encoders for motion-capture data, the new encoder operates in an “online”

mode—encoding the data as they are captured—which makes it ideal for low-latency, interactive virtual- and augmented-reality applications. APEGBC member: Dr. Ivan V. Baji ć , P.Eng.
