Controlling Drones with the Human Brain

A researcher from Arizona State University wants to command machines with the human brain. In fact, within ten years, Panagiotis Artemiadis, professor of mechanical and aerospace engineering at Arizona State University, envisions a swarm of brain-controlled drones playing a critical role in a range of applications, including agriculture and search-and-rescue operations.

Antenna Basics

The antenna is the most intrinsic component of all RF systems, yet the principles of antenna design and wave propagation are rarely discussed outside the entry level engineering classes. Rohde & Schwarz has developed an educational white paper on Antenna Basics to reteach the basic principles in a simplified manner.

Rare Material Could Shorten Air Travel Times

An average flight from Miami to Seattle takes about six hours and 40 minutes, but imagine being able to reduce that time to 50 minutes or less. A recent study by NASA and Binghamton University researchers focuses on boron nitride nanotubes (BNNTs).

Testing Large–Scale Vehicle–Borne Improvised Explosive Devices

In July of 2016, a refrigerator truck packed with explosives detonated next to a crowded apartment block in Baghdad’s Karrada neighborhood. The blast killed 323 people and was one of the worst Vehicle–Borne Improvised Explosive Device (VBIED also known as car bombs) attacks ever recorded. On May 30, 2017, a VBIED in a tanker truck ripped through the embassy quarter of Kabul, killing more than 150 people. Several embassies, including those of Germany and France, sustained damage despite the presence of blast protection structures.

Army Scientists Discover Power in Urine

Scientists at the U.S. Army Research Laboratory observed an unexpected result when combining urine with a newly engineered nano-powder based on aluminum. It instantly releases hydrogen from the urine at a much higher rate than with ordinary water.

Putting Smart Weapons to The Test

In the old days, a slingshot, BB gun, rifle or cannon was only as smart as the marksman taking aim. Now, many weapons are guided to their targets with the precision of infrared sensors and lasers. The technology continues to advance, but testing technology has lagged behind, leaving new generations of weapons and their tactical advantages unavailable to today's troops.

Sensitivity Simulation of Compressed Sensing Based Electronic Warfare Receiver Using Orthogonal Matching Pursuit Algorithm

Electronic Intelligence Receiver (ELINT) is an important component in electronic warfare (EW) and layer sensing. The information it provides by constant surveillance can be used to detect, track and classify signals across the electromagnetic spectrum. The proper identification and reaction to the threat can avoid disaster and assure spectrum dominance for Air Force systems.

The Impact of Video Compression on Remote Cardiac Pulse Measurement Using Imaging Photoplethysmography

Remote measurement of physiological signals has a number of advantages over traditional contact methods. It allows the measurement of vital signals unobtrusively and concomitantly. In recent years, a number of approaches for imaging-based measurement of physiology using digital cameras have been proposed. Imaging photoplethysmography (iPPG) captures variations in light reflected from the body due to blood volume changes in microvascular tissue. It has been demonstrated that sub-pixel variations in color channel measurements from a digital single lens reflex (DSLR) camera, when aggregated, could be used to recover the blood volume pulse. Subsequently, it was shown that iPPG methods can allow accurate measurement of heart rate, heart rate variability, breathing rate, blood oxygenation and pulse transit time.
