Spectroscopic Studies of Isomers Produced in Relativistic Projectile Fragmentation and In-Flight Fission

This thesis is based on a number of experiments performed at the FRagment Separator (FRS) at the Gesellschaft für Schwerionenforschung mbH (GSI) in Darmstadt, Germany, in which heavy-ion reactions at relativistic energies have been used to produce nuclei far from stability. In April 1999 projectile fragmentation of 208Pb at 1 GeV/nucleon was used to study so called K-isomers in the neutron-rich i

Object-Tokens in High-Level Grafchart

The paper presents an high-level extension to Grafchart, a Grafcet-based toolbox for supervisory control applications. The extension allows tokens to be objects with attributes. Contrary to most high-level extensions to Petri Nets and Gracet it is not based on inscriptions.
