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 ...

Abstract: An extension of the CORDIC (coordinate rotation digital computer) algorithm that makes it possible to compute the functions cos/sup -1/, sin/sup -1/, square root 1-t/sup 2/, sinh/sup -1/ ...
