The nature of war refers to the aspects of war that are enduring across time and the change in weapons, states, and societies. It is widely agreed that war has been and will remain a violent act of force, subordinated…
The performance of electronics degrades as temperature increases from the ambient temperature. The temperature of a device increases when the device is on since no system operates at 100% efficiency. Output power is not equal to the power fed to…
The past few decades have seen an escalation of power densities in electronic devices, and in particular in microprocessor chips. Together with the continuing trend of reduction in device dimensions this has led to dramatic increase in the thermal issues…
The armed drones like MQ-1 Predator and its larger cousin, MQ-9 Reaper, dual intelligence, surveillance and reconnaissance-strike platforms have been highly successful against non-state actors as part of the counterterrorism fight. A MQ-1 Predator UAVs armed with Hellfire missiles have…
Most of the ocean is unknown. Yet we know that the most challenging environments on the planet reside in it. Understanding the ocean in its totality is a key component for the sustainable development of human activities and for the…
In traditional aircraft design, airframes and engines are designed separately and bolted together. This leads to inefficiencies due to additional drag. The approach also leads to propulsive inefficiencies via non-distributed propulsion. Hovering and VTOL requirements introduce even more complexity, size…
The civil global aviation market has experienced considerable economic growth in recent years and will keep increasing. It is estimated that around 1300 new international airports will be required, and the commercial aircraft fleet will double by 2050, with a…
Unmanned aerial vehicle technology is advancing rapidly, and drones are getting smaller by the day. Militaries are now employing Micro, Mini & Nano UAVs into their operations. They provide situational awareness to a small group of soldiers by flying several…
The control of electric currents in solids is at the origin of modern electronics which has revolutionised our daily life. The diode and the transistor introduced by Braun and Bardeen and Brattain are undoubtedly the corner stones of modern information…
The amount of electricity consumed worldwide grows by the year, and so does the demand for energy storage solutions since many devices often operate in autonomous mode. Rechargeable lithium-ion batteries have been workhorse of the consumer electronics market including portable…
