Maritime networks have become an attractive playground for hackers, with cyber-attacks on vessel OT networks and systems increasing by 900% over the past three years.  A ship’s onboard information technology and operational technology systems can be hacked just as easily as systems ashore. Such security breaches have the potential to …

The UK has a thriving space industry that generates an income of £14.8 billion [$20.57 billion] each year. The UK Space Agency’s aim is to drive growth into the UK economy by supporting the development of space technology and skills, as embodied in the UK Space, Innovation and Growth Strategy (Space …

Broadband fiber-optics carry information on pulses of light, at the speed of light, through optical fibers. But the way the light is encoded at one end and processed at the other affects data speeds. Basically, light or any other electromagnetic radiation has energy defined by its frequency and momentum defined by …

Space-division multiplexing (SDM) has recently attracted great attention as a promising technology to further improve the transmission capacity and spectral efficiency. Very recently, SDM employing twisted lights, also known as orbital angular momentum (OAM) carrying lights, provides an alternative approach to increasing the transmission capacity and spectral efficiency of optical communications. …

“Between 2011 and 2018, WHO tracked 1483 epidemic events in 172 countries. Epidemic-prone diseases such as influenza, severe acute respirator syndrome (SARS), Middle East respiratory syndrome (MERS), Ebola, Zika, plague, yellow fever and others are harbingers of a new era of high-impact, potentially fast-spreading outbreaks that are more frequently detected …

Stealth technology has proven to be one of the effective approaches to enhance the survivability of Aircrafts. Aircraft/helicopter designers are making them stealthier by reducing their signatures; viz. visual, aural, infrared (IR), and RADAR cross section. Advancements in stealth technologies, as demonstrated by the very low RCS of stealth aircraft …

Since the Industrial Revolution, the environmental impacts of energy have posed a concern. Recently, this has driven researchers to search for viable options for clean and renewable energy sources. Due to its affordability and environmental friendliness, hydrogen is a feasible alternative to fossil fuels for energy applications. However, due to its …
