Police agencies are  using facial and object recognition technology for counterterrorism operations. Video footage  played a key role in finding the culprits responsible for the November 2015 Paris attacks, with a CCTV video at Brussels airport used to pin down one suspect. But, the sheer volume of video content produced …

Currently, the most widely used technology to detect underwater objects  is sound navigation and ranging (SONAR), because acoustic waves can  penetrate the water depths to the bottom of the sea. SONAR also suffers from unwanted multipass echoes that are due to reflections from the surrounding terrain. Thus, high-resolution underwater imaging …

The phonon is the physical particle representing mechanical vibration and is responsible for the transmission of everyday sound and heat. Understanding and controlling the phononic properties of materials provides opportunities to thermally insulate buildings, reduce environmental noise, transform waste heat into electricity and develop earthquake protection.   The concept of …

In the wake of increasing electronic gadget sales, the overheating problem for battery chargers has become an increasingly common safety issue. Overheating of chargers certainly can be caused by substandard chargers, faulty batteries, or by misuse of the chargers. In worst-case scenarios the devices melt or catch fire. Unsurprisingly, this …

The U.S.  Navy and DARPA ran a facility–the High Frequency Active Auroral Research Program (HAARP) in Gakona, Alaska—before it was passed to the University of Alaska in 2014. HAARP  was a research program to study ionosphere and its response to high frequency excitations from ground. “The official objective of the …

Manufacturing today benefits from three waves of innovation: new production techniques (like 3-D printing), new design methods (like generative design, also driven by A.I.) and new materials, said Marco Annunziata , Co-Founder of Annunziata.   These three waves of innovation are interdependent and mutually reinforcing: 3-D printing allows us to …

Graphene is a 1-atom-thick layer of tightly bonded carbon atoms arranged in a hexagonal lattice. Graphene the world’s first 2D nanomaterial, is widely regarded as the “wonder material” of the 21st century due to the combination of its extraordinary properties. As a single layer of graphite, it is the thinnest …

A global race has ensued to exploit and operationalize quantum technologies for the use of military effects. Quantum information science (QIS),  field comprises four domains: Quantum Communication, where individual or entangled photons are used to transmit data in a provably secure way; Quantum Simulation, where well-controlled quantum systems are used …

Although the hardware and software technology for fully autonomous cars is ready today, the cars themselves may still be a decade or more away, vehicle experts said at the recent North American International Auto Show in Detroit. The challenge for automakers and suppliers lies in test and validation, as well …

GPS hacking and spoofing have made headlines around the world in recent years, from researchers successfully hacking a yacht’s navigation to bring it off its programmed course to the discovery of dozens of Russian ships whose GPS signals indicated they were on land when they were in fact out on …
