  2. 2. Optimization of Maintenance Planning for Multi-Component Systems, and Primal-Dual Convergence Characterizations in Convex Optimization

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Magnus Önnheim; Göteborgs universitet.; Gothenburg University.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; subgradient methods; Lagrangian dual; primal recovery; inconsistent convex programs; ergodic sequences; maintenance scheduling; preventive maintenance; deterioration cost;

    Sammanfattning : This thesis considers two topics within mathematical programming. The first topic is an investigation into the behaviour of primal-dual subgradient algorithms with primal ergodic averaging in the case where it is not known a priori whether the primal program is consistent or not.

  3. 3. Limit Theorems for Ergodic Group Actions and Random Walks

    Detta är en avhandling från Stockholm : KTH

    Författare :Michael Björklund; KTH.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : This thesis consists of an introduction, a summary and 7 papers. The papers are devoted to problems in ergodic theory, equidistribution on compact manifolds and random walks on groups.In Papers A and B, we generalize two classical ergodic theorems for actions of abelian groups.

  4. 4. Certain results on the Möbius disjointness conjecture

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Davit Karagulyan; KTH.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dynamical Systems; Ergodic Theory; Number Theory; Matematik; Mathematics;

    Sammanfattning : We study certain aspects of the Möbius randomness principle and more specifically the Möbius disjointness conjecture of P. Sarnak. In paper A we establish this conjecture for all orientation preserving circle homeomorphisms and continuous interval maps of zero entropy. LÄS MER

  5. 5. Contributions to dual subgradient optimization and maintenance scheduling
