Summary:
Engineers at the University of Toronto have developed a software program that could save the transportation, mining and manufacturing industries millions of dollars by telling them the optimal time to renew, repair or replace aging equipment.

Engineers at the University of Toronto have developed a software program that could save the transportation, mining and manufacturing industries millions of dollars.

The software, known as EXAKT, indicates the optimal time to renew, repair or replace equipment, says Professor Andrew Jardine of the department of mechanical and industrial engineering, one of the project's two principal researchers. The program, using mathematical models and equations, focuses on the equipment's current performance data as well as economic factors such as the initial cost of the equipment and estimated resale value of machine parts.

"This new software allows maintenance managers, for the first time, to combine risk assessment and economic considerations in terms of decision-making for industrial equipment," Jardine says. "The cost of replacing an item after it has failed completely will obviously be greater than replacing it under preventive conditions. It's not just a matter of running equipment into the ground."

Currently, managers considering parts replacement rely on one of two approaches -- the age-based technique that calculates equipment longevity based on the age of the equipment or the condition-based approach that relies on other measures such as the level of mineral-to-oil ratios in equipment.

Research was funded by the Natural Sciences and Engineering Research Council, Materials and Manufacturing Ontario, a provincial centre of excellence, and the Condition-Based Maintenance Consortium, an international partnership that includes various industries in Canada, the United States and Hong Kong.

Chameleon Camouflage to Give Tanks Cloaking Capabilities

Reuters - Innovations Video Online (Oct. 22, 2014) — Inspired by the way a chameleon changes its colour to disguise itself; scientists in Poland want to replace traditional camouflage paint with thousands of electrochromic plates that will continuously change colour to blend with its surroundings. The first PL-01 concept tank prototype will be tested within a few years, with scientists predicting that a similar technology could even be woven into the fabric of a soldiers' clothing making them virtually invisible to the naked eye.
