Helicopters and small aircraft flying at low altitude in the visual flight rules often strike against obstacles. According to the aircraft accident reports in Japan, many collisions by small aircraft were caused by long, thin artificial objects as power lines because they are often very difficult to find by pilot …

Criminals and militants have now started using swarm of commercial available drones thereby engancing their effectiveness and lethality. Military is also developing swarms for many applications including ISR, decoys or as swarm of weapons. Swarms are expected to be effective even in A2/AD environments.   Instead of being individually directed …

Neutrinos are some of the most mysterious particles in the universe. They’re strange, exotic bits of matter that are emitted by some nuclear reactions, and travel through space at nearly the speed of light. Trillions of them are created by the sun every second, and when they reach the Earth …

A fuel cell is a device that generates electricity by a chemical reaction. It converts hydrogen and oxygen into water, and in the process also creates electricity. Fuel cells provide many advantages, they are environment friendly as they don’t produce pollutants or greenhouse gasses, significantly improving our environment, high energy efficiency ( …

The need for more energy-efficient computers is urgent. The Department of Energy projects that, with the computer chip industry expected to expand to several trillion dollars in the next few decades, energy use by computers could skyrocket from 3 percent of all U.S. energy consumption today to 20 percent, nearly …

Sensors allow humans to feel and understand their world, and their development lays the foundation for the fulfillment of information society and has formed a huge industry. Photonic sensors are defined as sensors that sense, emit, receive and convert the light energy into electrical signals. Photonics sensors deal with the …

Sensors allow humans to feel and understand their world, and their development lays the foundation for the fulfillment of information society and has formed a huge industry. For its implementation the Internet of Things relies heavily on sensor technology.In the grand world of the “internet of things” (IoT), there are …

From an engineering perspective, computing is the systematized and mechanized manipulation of patterns.  A representation is a pattern in some physical medium, for example, the configuration of ONs and OFFs on a set of switches. The algorithm then tells us how to change these patterns—how to set the switches from …

Open source software is free to license, the preferred choice of geeks everywhere, for rapid development for instance impromptu mapping projects to help victims of the 2010 Haiti Earthquake where open source delivered results much faster than traditional methods. “It probably would have taken a year to come up with …
