    Notes: Abstract One possibility to estimate and to interpret the source parameters of low-stress drop seismic events to use the barrier or the asperity model. These models serve as the description of seismic events in a in which a horizontal room and pillar mining method is used in great depth. An additional macroseismic parameter, the destroyed or damaged area in the mine, allows the estimation of the real static stress drop of mining-induced seismic events. This stress drop, derived from a simplified barrier-or asperity-model, appears to be a constant and a characteristic parameter for a given source region. On this base, a relation between the underground destruction or damages and the seismologically estimated parameters is derived and is used for the classification of the mining-induced seismic events.

    Distributed nuclear medicine applications using World Wide Web and Java technology (2000)
    Springer
    European radiology 10 (2000), S. 1483-1486

    Notes: Abstract. At present, medical applications applying World Wide Web (WWW) technology are mainly used to view static images and to retrieve some information. The Java platform is a relative new way of computing, especially designed for network computing and distributed applications which enables interactive connection between user and information via the WWW. The Java 2 Software Development Kit (SDK) including Java2D API, Java Remote Method Invocation (RMI) technology, Object Serialization and the Java Advanced Imaging (JAI) extension was used to achieve a robust, platform independent and network centric solution. Medical image processing software based on this technology is presented and adequate performance capability of Java is demonstrated by an iterative reconstruction algorithm for single photon emission computerized tomography (SPECT).

    Absolute Raman efficiencies as a tool to investigate HTc cuprates (1996)
    Springer
    Journal of low temperature physics 105 (1996), S. 383-388

    Notes: Abstract Absolute Raman efficiencies of phononic, electronic and spin excitations have been determined for doped and undoped HTc-cuprates. Anomalous temperature dependence of the Raman efficiency of the phononic 500cm−1 mode is explained as a change of the apical oxygen position. The normal state efficiency of the. ‘electronic’ background in YBa2Cu3O6.9 has been obtained for various scattering geometries for Raman shifts up to 8000cm−1. The 2-magnon contribution to the magnetic Raman signal of the undoped and lightly doped cuprates has been measured quantitatively and compared with recent calculations based on the 3-band-Hubbard model. Possible contributions of magnetic Raman scattering to the electronic B1g background of the superconducting samples are discussed.
