A bright future is seen for advanced ceramic fibers and fiber coatings for high-temperature ceramic matrix composites (CMCs). But first design engineers must have better access to the information they need to select the new materials. So concludes a panel of the Commission on Engineering and Technical Systems of the National Research Council. Classified projects have generated most data on the tough, stable CMCs. Much of the information probably can be made public now, the report says. It urges creation of a database of CMC properties. Still, technical shortcomings must be overcome before CMCs can be widely used in thermostructural applications. The panel notes that fiber coatings for non-oxide composites have demonstrated adequate performance in short-life applications, such as rocket nozzles. However, fiber-coating technologies for long-life applications, such as turbine engine components, have yet to be demonstrated in component testing. Advances have been further impeded by the high cost of coated fiber. The panel thinks costs will drop through mass production as designers employ CMCs in a larger number of applications.
Enabling the Future is designing prosthetic appendages modeled more like superhero arms and hands than your average static artificial limbs. And they’re doing it through a website and grassroots movement inspired by two men’s design and creation in 2012 of a metal prosthetic for a child in South Africa.
In order to keep an enterprise truly safe from hackers, cyber security has to go all the way down to the device level. Icon Labs is making the point that security has to be built into device components.
Three days after NASA's MAVEN probe reached Mars, India's Mangalyaan probe went into orbit around the red planet. India's first interplanetary mission, and the first successful Mars probe launched by an Asian nation, has a total project cost of nearly $600 million less than MAVEN's.
Plant user interfaces are beginning to incorporate the consumer features such as swipe, double tap, and pinch. The driver is Millennials who expect plant equipment to match the sophistication of the smartphone.
