“Drip irrigation came to California in the 1970s, letting farmers plant more fruits, vegetables, and nuts more closely together and in desert areas not naturally suited for agriculture.”
The bunker door will be opened because the igniter, also called nitrocellulose, burns very rapidly and is only explosive when confined, Brian Salvatore, chairman of the chemistry and physics department at Louisiana State University in Shreveport and a member of the Camp Minden citizens’ advisory committee, said last week.
A magazine holding 114,000 pounds of igniter is scheduled for burning Saturday. Another one holding 84,000 pounds of igniter and 40,000 pounds of M6 artillery propellant is to be burned Oct. 29.
In Brief:
The U.S. may be trailing behind China in artificial intelligence (AI) research — or at least in journal articles that mention “deep learning” or “deep neural network” — according to the White House’s National Artificial Intelligence Research and Development Strategic Plan.
In the near future, we’re going to see an increasing number of Collision Avoidance System-equipped cars on the roads. Stated simply, the technology uses an integrated forward-looking radar system to alert drivers when they’re rapidly approaching obstacles such as other vehicles. If those other vehicles are bicycles, however, their rear profile can make them difficult for the radar to detect. That’s where iLumaware’s Shield TL comes in.
Inventors Chris Mogridge and Alexis Stobbe created the device by analyzing how stealth technology works, then essentially going in the opposite direction – whereas stealth vehicles are designed to evade radar signals, the Shield is made to catch those signals and reflect them back to the cars. It does this purely via its unique shape, not emitting any actual signal itself.
In field tests, it boosted bicycles’ radar signature by up to 100 percent, and thus increased the distance at which they could be detected by Collision Avoidance Systems.
Physicists on the Borexino neutrino experiment at Italian physics laboratory INFN in Gran Sasso announced in Nature that they have detected neutrinos produced deep inside the sun.
Neutrinos, which constantly stream through us, interact very rarely with other matter. When created in nuclear reactions inside the sun, they fly through dense solar matter in seconds and can reach the Earth in eight minutes.
The Global Positioning System (GPS) is a great navigation aid – unless you lose the signal while negotiating a complicated spaghetti junction. That’s bad enough for conventional cars, but for autonomous vehicles it could be catastrophic, so the University of California, Riverside’s Autonomous Systems Perception, Intelligence, and Navigation (ASPIN) Laboratory under Zak Kassas is developing an alternative navigation system that uses secondary radio signals, such as from cell phone systems and Wi-Fi to either complement existing GPS-based systems or as a standalone alternative that is claimed to be highly reliable, consistent, and tamper-proof.
Today, there are two global satellite navigation systems in operation, the US GPS and the Russian GLONASS, with the European Galileo system set to become fully operational in the next few years, and plans for the Chinese Beidou system to extend globally by 2020. These have revolutionized navigation, surveying, and a dozen other fields, but GPS and related systems still leave much to be desired. By their nature, GPS signals are weak and positions need to be confirmed by several satellites, so built up areas or mountainous areas can make the system useless. In addition, GPS signals can be deliberately or accidentally jammed or spoofed due to insufficient encryption and other protections.
An antimatter propulsion drive probe could be the first human-made spacecraft to orbit the newly-discovered extrasolar earthlike planet Proxima b. Or so says Gerald Jackson, the president of the Chicago-based Hbar technologies, whose antimatterdrive.org began a $200,000 Kickstarter campaign this weekend.
The idea is to use the fledgling antimatter propulsion technology to travel 4.2 light years to the newfound exo-earth circling Proxima Centauri, the Sun’s nearest stellar neighbor.
“Our antimatter drive project proposes an initial mission taking as long as 90 years, traveling at 5% of the speed of light for the majority of that duration,” Jackson, a former Fermilab physicist, told me. The hope is that the craft could eventually go into orbit around a nearby earthlike planet such as Proxima b.
