Optronics, surveillance and sighting systems allow defence forces to effectively locate, track, observe and engage a range of targets in land, airborne and maritime warfare domains both during daylight and after dark. These military-grade systems play a vital role in border security, base protection, patrol and intelligence, surveillance and reconnaissance (ISR) missions. Unmanned…...

Currently, old-style personal Medicare techniques rely mostly on traditional methods, such as cumbersome tools and complicated processes, which can be time-consuming and inconvenient in some circumstances. Furthermore, such old methods need the use of heavy equipment, blood draws, and traditional…...

Today, we are witnessing the second quantum revolution, where quantum states, which can exhibit superposition and entanglement, are harnessed for quantum technological applications. Quantum Sensing exploits the high sensitivity of quantum systems to external disturbances to develop highly sensitive sensors. …...
