    Description / Table of Contents: Übersicht In der Arbeit wurde die Bubnov-Galerkin-Methode in Verbindung mit der Methode der Variablentrennung zur Ermittlung der Verluste, die durch Wirbelströme und elektrodynamische Kräfte in zylindrischen Segmenten (Joffe-Schienen) hervorgerufen wurden, verwendet. Die Segmente befinden sich in einem homogenen magnetischen Querfeld, das sinusoidal veränderlich mit der Zeit ist. Die Berechnung wurde iterativ mit einem Digitalrechner vorgenommen. Diagramme der Verluste und Kräfte werden angegeben.
    Notes: Contents In the paper, eddy current losses and electrodynamic forces in cylindrical segments (Joffe's conductor) placed in a transverse homogeneous magnetic field sinusoidally changing with time were determined by means of the Bubnov-Galerkin method coupled with the separation of variables. Numerical computation served as a basis for plotting both real power losses and electrodynamic forces.

    Notes: Abstract The multiphonon method based onβ andγ phonons is tested in a simple model allowing an exact solution for a many body fermion system where pairing and quadrupole forces are acting. The properties exhibiting the anharmonicities of the lowest-lying vibrational states of positive parity are nicely reproduced by this method.
