  1. 1. Analysis of traffic load effects an railway bridges

    Author : Gerard James; KTH; []
    Keywords : bridge; rail; traffic load. Load effect. Dynamic amplification factor; extreme value theor; peaks-over-threshold;

    Abstract : The work presented in this thesis studies the load and loadeffects of traffic loads on railway bridges. The increasedknowledge of the traffic loads, simulated using fieldmeasurements of actual trains, are employed in a reliabilityanalysis in an attempt at upgrading existing railwaybridges. READ MORE

  2. 2. Moment Estimation Using Extreme Value Methods

    Author : Joachim Johansson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Pareto distribution; mean estimation; heavy tailed distributions; telecommunication; m -dependence; superpopulation sampling; peaks over threshold; telecommunication;

    Abstract : The thesis is composed of three papers, all dealing with the application of extreme value methods to the problem of moment estimation for heavy-tailed distributions. In Paper A, an asymptotically normally distributed estimate for the expected value of a positive random variable with infinite variance is introduced. READ MORE

  3. 3. Dynamics and Extreme Value Problems for Moored Floating Platforms

    Author : Yungang Liu; Chalmers University of Technology; []
    Keywords : quasi-static; frequency-domain; extreme value; convolution; floating platform; low-frequency; time-domain; mooring cable; wave-frequency;

    Abstract : This research deals with the dynamic response analyses and extreme value problems of moored floating platforms. It can be divided into three major subjects: first, the analysis of single cables and cable induced mooring damping; second, the dynamic analysis of the moored platforms, with special emphasis on the damping mechanisms and generation of the low-frequency excitation force time series; and third, the extreme wave-frequency responses and the combination of the low-frequency and wave-frequency extreme responses.
