Visuals from the European Space Agency’s Solar Orbiter reveal chaotic solar magnetism in the solar polar region. Even better images are expected in the years ahead.

Abstract: The application of an anthropomorphic retina-like visual sensor and the advantages of polar and log-polar mapping for visual navigation are investigated. It is demonstrated that the motion ...

translation and rotation operations, distance calculation, intersections, orthogonal projections of one object into another, etc. The objects can be defined in global or in one of the local coordinate ...

Abstract: In this paper, we propose novel OWC-MIMO modulation scheme which efficiently uses the polar coordinate. Our new optical spatial modulation with polar coordinate is designed to easily adapt ...

However, experts emphasize this short-term gain does not rev... Scientists have uncovered a surprising feature of polar bear fur: a natural oil that prevents ice accumulation. Unlike penguins ...

Say goodbye to field rotation with the Seestar S50! Watch how this telescope’s polar alignment feature makes your astrophotography experience smoother and more accurate. Mark Carney says ...
