Solid state cooling based on magnetocaloric, electrocaloric, and mechanocaloric materials advancing to replace present environmentally damaging refrigeration technologies

October 11, 2017 Comments Off on Solid state cooling based on magnetocaloric, electrocaloric, and mechanocaloric materials advancing to replace present environmentally damaging refrigeration technologies

Current cooling technology, such as that found in fridges and air conditioning systems, exploits the changes in temperature when gases are compressed and expanded. This technology often uses environmentally damaging greenhouse gases. The search for materials with large caloric effects has become a major challenge in material science due to …

Quantum Biometrics that Exploits the Human Eye’s Ability to Detect Single Photons, may be solution to military and security requirement of hackproof Biometrics

October 7, 2017 Comments Off on Quantum Biometrics that Exploits the Human Eye’s Ability to Detect Single Photons, may be solution to military and security requirement of hackproof Biometrics

Biometric verification is any means by which a person can be uniquely identified by evaluating one or more distinguishing biological traits. Unique identifiers include fingerprints, hand geometry, earlobe geometry, retina and iris patterns, voice waves, DNA, and signatures. A record of a person’s unique characteristic is captured and kept in …

DARPA’s Colosseum, world-unique wireless testbed shall catalyze the advent of autonomous, intelligent, and collaborative radio technology

October 2, 2017 Comments Off on DARPA’s Colosseum, world-unique wireless testbed shall catalyze the advent of autonomous, intelligent, and collaborative radio technology

In March 2016, DARPA officials launched the Spectrum Collaboration Challenge (SC2), an initiative designed to ensure that the exponentially growing number of military and civilian wireless devices will have full access to the increasingly crowded electromagnetic spectrum particularly between 9 kHz and 275 GHz, the range allocated by the Federal …
