    Singularity Control for Simple Manipulators Using “Path Energy”

    A new method is presented for controlling the trajectories of straight-line Cartesian paths near the kinematic singularities of simple manipulators. Conventional approachs to this problem, which typically empl...

    Nachweis von Reflex-Bluten bei Lampyriden (Coleoptera) mit Hilfe der „Tracer”-Methode

    The very short time (5–9 min) between injection of radiophosphorous into the hemolymph of adult fireflies (Lampyridae) and outflow of radioactive droplets after irritation demonstrates with certainty that refl...
