    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; contact forces; Karhunen–Loève expansion; dynamic train–turnout interaction; field test; wheel–rail contact geometry; stochastic analysis; switches and crossings; SRA - Transport;

    Sammanfattning : Two models for simulation of dynamic interaction between train and turnout are developed. The first one is derived using a commercial software for dynamics of multi-body systems. LÄS MER

  5. 44. Simulation of Relaxation Processes in Fluorescence, EPR and NMR Spectroscopy

    Författare :Pär Håkansson; Per-Olof Westlund; Yehudi K. Levine; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; EPR; NMR; Energy migration; bicontinuous cubic phase; Stochastic Liouville Equation; Brownian Dynamics; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Relaxation models are developed using numerical solutions of the Stochastic Liouville Equation of motion. Simplified descriptions such as the stochastic master equation is described in the context of fluorescence depolarisation experiments. Redfield theory is used in order to describe NMR relaxation in bicontinuous phases. LÄS MER

  7. 45. Voltage Dip (Sag) Estimation in Power Systems based on Stochastic Assessment and Optimal Monitoring

    Författare :Gabriel Olguin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power quality; symmetr?cal components; stochastic methods; impedance matrix; voltage dips; integer optimisation; power systems; short-circuit faults; voltage sags;

    Sammanfattning : This dissertation deals with the statistical characterization of the performance of power systems in terms of voltage dips (sags). It presents a method named voltage dip estimation that extends monitoring results to buses not being monitored. LÄS MER
