Gas Turbine Combustion Acoustics: The Silent, Disruptive Case Study in Condition-Based Maintenance
0 Reliability is an essential criterion for gas turbine and generator equipment for power generation systems. With a variety of power generation assets operating under differing market strategies, a unit’s reliability is characterized by successful starts, staying online for the course of dispatch, and delivering the performance that was anticipated when bidding into the electricity market.
Just4Kids: Why does a rocket have to go 25,000 mph to escape Earth?
Editor’s note: Welcome to Just4Kids, a new feature with content from The Conversation for Kids, a nonprofit in which scholars answer kids’ questions about science, health and more, that will be featured Saturdays in The Detroit News. There’s a reason why a rocket has to go so fast to escape Earth. It’s about gravity – something all of us experience every moment of every day. Gravity is the force that pulls you toward the ground. And that’s a good thing.

Fiber-coupled LWIR hyperspectral sensor suite for non-contact component surface temperature measurements
Abstract We report on the development of a robust fiber-coupled long-wavelength infrared (LWIR) hyperspectral sensor suite for accurate and reliable non-contact surface temperature measurements in propulsion systems with limited optical access. We first experimentally investigate various state-of-the-art LWIR optical fibers and identify the ideal fiber for efficient coupling and transmission of LWIR signals.
AFR: Tony Abbott's Team Australia rhetoric is getting crazy
By asking the ABC whose side it is on following the airing on Q&A of a question from a man who had been charged with terror offences Australia’s Prime Minister was essentially accusing the national broadcaster of supporting terrorism. It’s part of a pattern. Eighteen months ago, the Prime Minister accused the ABC of taking “everybody’s side but Australia’s.” It seems the Prime Minister will decide who is on Team Australia and the circumstances in which they are selected.
AFR: Ignore the Sirens of Opportunism
Last week’s decision by Labor to oppose tighter assets testing of the age pension revived memories of Paul Keating paying me a visit as Bob Hawke’s microeconomic adviser back in 1989. “This is the worst decision the government has ever made,” Paul thundered, “and I hold you personally responsible.” Paul was referring to a government decision to offer a $36 million subsidy to keep Kodak’s Melbourne factory doors open.
