Highly Accurate Realtime Clocksynchronization with GPS Time Receivers.

Es wird das Potential aufgezeigt, das GPS-Zeitempfaenger heute fuer die Synchronisation von Stationen in Abstaenden bis zu 200 km liefern zu koennen. Eine relative Genauigkeit von besser 10 ns scheint erreichbar. Operationelle Geraete sind allerdings noch nicht auf dem Markt

Dynamical control: Comparison of map and continuous flow approaches.

Continuous and pulsed forms of control of a multistable system are compared directly, both theoretically and numerically, taking as an example the switching of a periodically driven class-B laser between its stable and unstable pulsing regimes. It is shown that continuous control is the more energy efficient. This result is illuminated by making use of the close correspondence that exists between the problems of energy-optimal control and the stability of a steady state
