A new power revolution is going on in orbit – that of electrical propulsion for satellites. An ion thruster is a form of electric propulsion used for spacecraft propulsion. It creates thrust by accelerating ions with electricity. As the ionised particles escape from the aircraft, they generate a force moving …

We are in midst of the second quantum revolution moving from merely computing quantum properties of systems to exploiting them. Researchers are developing new capabilities in secure communication, ultra-sensitive and high signal-to-noise physical sensing of the environment and Quantum Information Science (QIS). Yet many scientists believe that quantum will …

The Arctic region encompasses the seas and land north of latitude 66.33° N. The Arctic Ocean is the smallest of the world’s oceans but is transforming due to its melting ice. Eight countries possess territories there: Canada, Denmark (through possession of Greenland), Finland, Iceland, Norway, Russia, Sweden and the US. …

As the Global warming is melting the Arctic ice, and opening up new shipping trade routes and real estate, intense resource competition over an estimated $1 trillion untapped reserves of oil, natural gas and minerals has started. Human activities have grown in the Arctic by almost 400 percent in the …

Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism’s DNA. These technologies allow genetic material to be added, removed, or altered at particular locations in the genome. Several approaches to genome editing have been developed. CRISPR is a …

Current weapons generally fly a pre-designated mission. If the enemy does something unexpected, preprogrammed weapons are ineffective, and additional weapons may be required to complete the mission. Networked, collaborative and semi-autonomous weapons are advantageous since they observe and react to the enemy in real time, helping weapons overcome adversary defenses …

UK Strategic Command is expected to invest £1.5 billion in the next ten years to “build and sustain a ‘digital backbone’ to share and exploit vast amounts of data, through the cloud and secure networks”, according to Defence Secretary Ben Wallace MP. Embedded military systems are the foundation of this …

The demands on Wireless communications and radar systems have been continuingly increasing as the need for accuracy, efficiency, and more advanced metrics become increasingly important. Many new applications will only be possible with antennas that consume less power in a lower profile than traditional mechanically steered dish antennas. These requirements …

Over the last few decades, we have seen tremendous improvements in the performance and energy efficiency of computing and memory systems. With the rise in cloud computing, mobile devices and data volume, the demand for large data centres and supercomputers is continuing to grow as a result. In 1965 …

Radar is an electromagnetic sensor used for detecting, locating, tracking, and recognizing objects of various kinds at considerable distances. It operates by transmitting electromagnetic energy toward objects, commonly referred to as targets, and observing the echoes returned from them. Energy is emitted in various frequencies and wavelengths from large wavelength radio …
