A research team from Japan has developed a single-camera machine vision algorithm, making it possible for lightweight hovering indoor robots to guide themselves by identifying and interpreting reference points on a tiled floor. The technology opens the door to a new breed of functional, low-cost drones with potentially wide-ranging uses.
It is difficult to make very wide frequency combs from silicon waveguides, but clever waveguide engineering may be about to make that task a bit easier.
The National Institute of Information and Communications Technology (NICT), the Japan Science and Technology Agency (JST), Toin University of Yokohama, and Chiba University have succeeded in developing a color-multiplexed holography system by which 3D information of objects illuminated by a white-light lamp and self-luminous specimens are recorded as a single multicolor hologram by a specially designed and developed monochrome image sensor.
Last December, Harvard researchers designed technology that could achieve the lowest temperature chemical reactions and then broke and formed the coldest bonds in the history of molecular coupling. Now, though reactions are considered too fast to measure, they determined the exact lifespan of their intermediate--the space between reactants and products--and solved the mystery of why some ultracold molecules simply disappear.
A robot travelling from point A to point B is more efficient if it understands that point A is the living room couch and point B is a refrigerator. That's the common sense idea behind a 'semantic' navigation system developed by Carnegie Mellon University and Facebook AI Research. That navigation system last month won the Habitat ObjectNav Challenge at the Computer Vision and Pattern Recognition conference
A new device that relies on flowing clouds of ultracold atoms promises potential tests of the intersection between the weirdness of the quantum world and the familiarity of the macroscopic world we experience every day.
In a breakthrough experiment, physicist and engineers at the CUNY ASRC have shown that it is possible to limit the movement of sound to a single direction without interruption even when there are deformations along the pathway. The findings pave the way for technologies with more robust sound wave integrity and advances in ultrasound imaging, sonar, and electronic systems that use surface acoustic wave technology.
Skoltech researchers and their industry colleagues have created a data-driven model that can forecast the production from an oil well stimulated by multistage fracturing technology. This model has high commercialization potential, and its use can boost oil production via optimized fracturing design.
The Internet has deeply changed our ways of living but at the same time introduced serious security and privacy issues. The quantum internet promises to fundamentally solve these issues. Currently however, the major obstacles towards its development are the scarcity of quantum resources. Researchers in Japan have taken a major step forward by significantly reducing the number of resources required for such tasks. They published their findings on May 27 in Physical Review Letters.
New model helps robots understand their environment as humans do.
