Algorithm Helps Autonomous Vehicles to Recognize Terrain in All Seasons
PASADENA, Calif., June 29, 2021 — An algorithm developed at Caltech enables autonomous vehicles to determine their location simply by looking at the terrain around them. For the first time, the technology works regardless of season, its developers said. The general process around which the current work (and algorithm) stems was developed in the 1960s and called visual terrain-relative navigation (VTRN). By comparing nearby terrain to high-resolution satellite images, autonomous systems can determine their
Parallel Reactors Unveil the Secrets of Soliton Molecules
ERLANGEN, Germany, June 29, 2021 — A team of scientists at the Max Planck Institute for the Science of Light has developed a platform called a parallel optical-soliton reactor, which can host massively dynamic events of soliton molecules. The parallel reactors resemble chemical...
