The article discusses a study that determines the viewing direction for solar occultation instruments from scans over the solar disk. It shows that the pointing control by SCIAMACHY's sun follower device allows to determine the azimuth pointing direction with a standard error. It found a small decrease of the mean tangent height offset in the first four years of the mission of 50m in total and a stable pattern since then.

    This paper presents a method for estimating position and orientation of multiple robots from a set of azimuth angles of landmarks and other robots which are observed by multiple omnidirectional vision sensors. Our method simultaneously performs self-localization by each robot and reconstruction...

    We analyze azimuthal anisotropy in heavy-ion collisions related to the reaction plane in terms of the standard reggeon approach and find that it is non-zero even when the final-state interaction is switched off. This effect can be interpreted in terms of the partonic structure of the colliding...
