  • A Bayesian estimation method for variational phase-field fracture problems 
    Khodadadian, Amirreza; Noii, Nima; Parvizi, Maryam; Abbaszadeh, Mostafa; Wick, Thomas; Heitzinger, Clemens (Berlin : Springer, 2020)
    In this work, we propose a parameter estimation framework for fracture propagation problems. The fracture problem is described by a phase-field method. Parameter estimation is realized with a Bayesian approach. Here, the ...
  • A multilevel Monte Carlo finite element method for the stochastic Cahn–Hilliard–Cook equation 
    Khodadadian, Amirreza; Parvizi, Maryam; Abbaszadeh, Mostafa; Dehghan, Mehdi; Heitzinger, Clemens (Heidelberg : Springer Verlag, 2019)
    In this paper, we employ the multilevel Monte Carlo finite element method to solve the stochastic Cahn–Hilliard–Cook equation. The Ciarlet–Raviart mixed finite element method is applied to solve the fourth-order equation. ...
  • A physics-based statistical model for human gait analysis 
    Zell, Petrissa; Rosenhahn, Bodo (Cham : Springer Verlag, 2015)
    Physics-based modeling is a powerful tool for human gait analysis and synthesis. Unfortunately, its application suffers from high computational cost regarding the solution of optimization problems and uncertainty in the ...
