When energy-saving becomes a game
(Phys.org) —A smartphone application bringing gaming dimensions to energy awareness has helped householders in Finland, Sweden and Italy reduce their electricity consumption by up to 19%.
Can control theory make software better?
"Formal verification" is a set of methods for mathematically proving that a computer program does what it's supposed to do. It's universal in hardware design and in the development of critical control software ...
Are you looking at me? A multi-system display that 'knows' when you're not looking
(Phys.org) —A new interactive multi-display system that can tell when you're not paying attention has been developed by scientists at the University of St Andrews.
Self-assembled nanostructures enable a low-power phase-change memory for mobile electronic devices
Nonvolatile memory that can store data even when not powered is currently used for portable electronics such as smart phones, tablets, and laptop computers. Flash memory is a dominant technology in this field, ...
Mobile LIDAR technology expanding rapidly
(Phys.org) —Imagine driving down a road a few times and obtaining in an hour more data about the surrounding landscape than a crew of surveyors could obtain in months.
New microscope measures nanomagnet property vital to 'spintronics' (w/ video)
Researchers at the National Institute of Standards and Technology have developed a new microscope able to view and measure an important but elusive property of the nanoscale magnets used in an advanced, experimental form ...
