The advancement of Sensors, Communications and Radars have given rise to Electronic Warfare, which encompasses, in all battle phases, military actions involving the use of EM energy to determine, exploit, reduce or prevent hostile use of EM spectrum and the actions, which retain friendly use of the EM spectrum. The …

Recent years have seen multiple new security challenges emerge in the maritime arena. Navies, coast guards and other maritime security agencies face a proliferation of security challenges. These include: illegal fishing of territorial waters; incursion of mineral exploitation across legal boundaries; maritime terrorism; narcotics smuggling; pollution as a result of …

“Electronics have dramatically changed the way we live, conduct business, communicate, and educate. Visions of the future foretell of ubiquitous computing and sensing. However, the environments in which electronics can reliably operate are limited. In consumer applications, typical operating temperatures range from -40° to 85°C. The “wider” military temperature range …

The emerging battlefield is a multi-domain battlefield which shall include all the traditional domains of land, air and sea as well as Cyber, Space, Low Intensity conflicts, Information warfare including Psychological warfare and cognitive warfare shall be exploited by our adversaries simultaneously or in any desired combinations.   Implementing multi …

US Naval Research Laboratory (Naval Research Laboratory, NRL)  has  allocated $ 45 million for the implementation of a program to study the prospects for the use of genetic engineering for the navy. Part of the program was the development of genetically modified microorganisms capable of detecting the presence of enemy ships, …

It was in the oceans that life first evolved and where complex animals have thrived for over 600 million years. Marine animals survive in environments as diverse as tropical coral reefs, polar ice-capped oceans, and the lightless abyssal depths, says Frank E. Fish from West Chester University and Donna M. …

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 …
