  1. 6. Reliability Assessment and Probabilistic Optimization in Structural Design

    Author : Rami Mansour; Mårten Olsson; Xioping Du; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability-based design optimization RBDO ; First- and Second-Order Reliability Method FORM and SORM ; Response Surface Single Loop RSSL ; Probability of failure; Reliability Assessment; Probability of fatigue failure; Hållfasthetslära; Solid Mechanics;

    Abstract : Research in the field of reliability based design is mainly focused on two sub-areas: The computation of the probability of failure and its integration in the reliability based design optimization (RBDO) loop. Four papers are presented in this work, representing a contribution to both sub-areas. READ MORE

  2. 7. On time-frequency analysis and pseudo-differential operators for vector-valued functions

    Author : Patrik Wahlberg; Joachim Toft; Luigi Rodino; Växjö universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : This thesis treats different aspects of time-frequency analysis and pseudodifferential operators, with particular emphasis on techniques involving vector-valued functions and operator-valued symbols. The vector (Banach) space is either motivated by an application as in Paper I, where it is a space of stochastic variables, or is part of a general problem as in Paper II, or arises naturally from problems for scalar-valued operators and function spaces, as in Paper V.

  3. 8. Higher-Order Regularization in Computer Vision

    Author : Johannes Ulén; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Regularization; Segmentation; Dense Stereo;

    Abstract : At the core of many computer vision models lies the minimization of an objective function consisting of a sum of functions with few arguments. The order of the objective function is defined as the highest number of arguments of any summand. READ MORE

  4. 9. Accurate Finite Difference Methods for Option Pricing

    Author : Jonas Persson; Lina von Sydow; Per Lötstedt; Johan Tysk; Jari Toivanen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Finite differences; Option pricing; Adaptive methods; Numerical Analysis; Numerisk analys;

    Abstract : Stock options are priced numerically using space- and time-adaptive finite difference methods. European options on one and several underlying assets are considered. These are priced with adaptive numerical algorithms including a second order method and a more accurate method. READ MORE

  5. 10. Estimation of Nonlinear Greybox Models for Marine Applications

    Author : Fredrik Ljungberg; Martin Enqvist; Svante Gunnarsson; Håkan Hjalmarsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : As marine vessels are becoming increasingly autonomous, having accurate simulation models available is turning into an absolute necessity. This holds both for facilitation of development and for achieving satisfactory model-based control. READ MORE
