Magneto resistor is a type of resistor whose resistance changes when an external magnetic field is applied. In other words, the flow of electric current through the magneto resistor changes when an external magnetic field is applied to it.   Magnetic field is the region present around a magnetic object …

Man-Portable Air Defense Systems (MANPADS) are surface-to-air missiles that can be carried and fired by a single individual or carried by several individuals and fired by more than one person acting as a crew. MANPADS were designed to be used by national military forces to protect their troops and facilities. With …

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.

“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 …

The claims by Nigeria’s government that terrorist group Boko Haram has been “defeated” continue to ring hollow. An attack by the terrorist group on an army base  in Nov 2018 led to as many as 100 soldiers being killed, Reuters reports. The attack has been attributed to Islamic State West …

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, …

Space situational awareness (SSA) is the foundational element of space security, and it entails keeping track of all natural and artificial space objects, energy and particle fluxes and understanding how the space picture is changing over time. SSA is a system of systems dealing with space surveillance, space weather and …

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. …
