Underwater communication is vital for undersea exploitation and modern communication. Conventional ways which employ acoustical technique for underwater communication have their drawbacks  including high path loss, narrow bandwidth, high bit error rate, among which unconditional security is more demanding due to commercial and secure interest.   Submarine communications have always been a challenge …

Alexander Graham Bell discovered photoacoustics by accident when he was working on the development of the photophone, a followup to his recently developed telephone that operated via modulated sunlight instead of electricity. You would operate a photophone by speaking into its transmitter toward a mirror placed inside of it. The vibrations …

As the space domain has become more congested, the potential for intentional and unintentional threats to space system assets has increased. Space is also becoming another domain of conflict due to enhanced militarization and weaponization of space. There has been enhanced testing of Anti-satellite weapons (ASAT) and space weapons designed …

The world, say many experts, is on the verge of a second quantum revolution. Energy quantization gave us modern electronics via the transistor and the laser, but humans’ burgeoning ability to manipulate individual atoms and electrons could potentially transform industries ranging from communications and energy to medicine and defense. The most …

Traditional missiles powered by rocket motors typically carry both fuel and oxidizer. An air-breathing ramjet missile can dispense with the separate oxidizer payload, reducing the size of a propulsion package.  Thanks to ramjets, smaller missiles use that space for other things, like a bigger warhead or more fuel. Ramjets, according to …

A database is an organized collection of data, generally stored and accessed electronically from a computer system. Where databases are more complex they are often developed using formal design and modeling techniques. The database management system (DBMS) is the software that interacts with end users, applications, and the database itself to …

Broadly speaking, cloud computing refers to the practice of remotely storing and accessing information and software programs on demand, instead of storing data on a computer’s hard drive or accessing it through an organization’s intranet. This practice relies on a cloud infrastructure, a collection of hardware and software that may …

“A supercomputer takes very complex problems and breaks them down into parts that are worked on simultaneously by thousands of processors, instead of being worked on individually in a single system, like a regular computer. Thanks to parallel processing, researchers and scientists can generate insight much faster considering a laptop …
