A Transistor-Like Amplifier for Single Photons

A Transistor-Like Amplifier for Single Photons

Data transmission over long distances usually utilizes optical techniques via glass fibres — this ensures high speed transmission combined with low power dissipation of the signal. For quite some years possibilities have been explored how to go one step further and perform all-optical data processing, with optical transistors and optical logic gates. In particular in [...]

Linking Television and the Internet

Linking Television and the Internet

In the “LinkedTV” project, researchers are seamlessly connecting TV offerings with the Internet. Audiences will benefit from an informative and personalized viewing experience.   The panel discussion is getting heated — but what exactly is in the new proposed law that the experts on TV are arguing about so vigorously? Up until now, spontaneous questions [...]

Software for Diagnosing Eye Sensitivity

Software for Diagnosing Eye Sensitivity

Researchers at the University of Alicante have developed high-precision software for diagnosing eye sensitivity. This is a new technology that allows to quantify the degree of opacity in the posterior capsule of the eye caused by the growth of cells in the intraocular lens.   The opacity of the posterior capsule is currently the most [...]

Testing Free-Flying Housekeeper Robots in Space

Testing Free-Flying Housekeeper Robots in Space

Inspired by science fiction, three bowling ball-size free-flying Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) have been flying inside the International Space Station since 2006. These satellites provide a test bed for development and research, each having its own power, propulsion, computer, navigation equipment, and physical and electrical connections for hardware and sensors for [...]

No-Wait Data Centers: Data-Transmission Delays Across Server Farms can be Reduced by 99.6 percent

No-Wait Data Centers: Data-Transmission Delays Across Server Farms can be Reduced by 99.6 percent

Big websites usually maintain their own “data centers,” banks of tens or even hundreds of thousands of servers, all passing data back and forth to field users’ requests. Like any big, decentralized network, data centers are prone to congestion: Packets of data arriving at the same router at the same time are put in a [...]
