A nuclear submarine is a submarine powered by a nuclear reactor. The performance advantages of nuclear submarines over “conventional” (typically diesel-electric) submarines are considerable. Nuclear submarines are more powerful than diesel-powered submarines because nuclear reactors powering them can run for years without the need for refuelling. Nuclear propulsion, being completely …

Industry developed new approach to protect against advanced ‘ROP’ Cyberattacks
Today’s cybersecurity playing field is fundamentally asymmetric. Attackers are easily able to identify weaknesses in a target system once they have access to its code and configuration. As a result, defenders are perpetually playing a game of catch-up to secure their systems post-attack. ROP attacks are particularly insidious in …

Phase Change Materials (PCMs) and Metal Hydride Heat Storage Technology for Directed Energy Weapon Systems
Recent advances of high power solid state lasers promises necessary laser power levels required for the Directed Energy Weapons (DEW) systems. However, inefficiencies of the laser components still generate too much waste heat to be managed by conventional liquid cooling systems, especially in an airborne platform where compactness, light-weight and …

Researchers use Graphene for miniature inductors enabling Ultra-Miniaturized Electronics Devices
The inductors along with capacitors and resistors, inductors are one of the three passive elements that are the foundations of all electronics. An inductor works by inducing a magnetic field as an electric current flows through its coil of wire. This magnetic field temporarily stores electric energy as magnetic energy, …
