  1. 1. A Borel-Cantelli lemma for non-stationary dynamical systems

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Teodor Åberg; [2023]
    Nyckelord :Borel-Cantelli lemmas; Dynamical systems; Mathematics and Statistics;

    Sammanfattning : In this thesis we present a Borel–Cantelli lemma for dynamical systems such that the dynamics driving the system varies with time. These results are largely based on a decomposition of transfer operators produced by Rychlik. Some limitations on the structure of sequences that is necessary for the results is given some discussion. LÄS MER

  3. 2. Start of a new design method for a competitive Small Modular Reactor (SMR) adaptable to future uses

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Baptiste Mazurié; [2023]
    Nyckelord :Requirement modelling; Cyber-physical systems; Small Modular Reactor SMR ; Systems Engineering; CRML;

    Sammanfattning : As cyber-physical systems become increasingly complex, the management and verification of requirements during design is essential. A new language called CRML (Common Requirement Modelling Language) has been created during the European EMBrACE project to formalize realistic dynamical requirements, but a method for representing these requirements and a framework for using them as a design aid must be defined to ease appropriation by engineers.

  4. 3. Dynamic Consequences of Bearing Radial Clearance in Jeffcott Rotors

    Kandidat-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Marcus Bohman; [2023]
    Nyckelord :;

    Sammanfattning : Earlier research on bearing radial clearance on a vertical Jeffcott rotor is rare, but an interesting and realistic point of view in a rotor system. Applying this force to the system produces interesting results for a vertical Jeffcott rotor. LÄS MER

  5. 4. Braids and configuration spaces

    Kandidat-uppsats, Uppsala universitet/Geometri och fysik

    Författare :Andersson Rasmus; [2023]
    Nyckelord :braids; braid groups; configuration space; algebraic topology; group theory; fundamental group; covering spaces;

    Sammanfattning : A configuration space is a space whose points represent the possible states of a given physical system. As such they appear naturally both in theoretical physics and technical applications. LÄS MER

  7. 5. Numerical modelling of high-speed railway transition zone

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Karl Norberg; [2022]
    Nyckelord :Railway geotechnics; Bridge; Ballastless track; Transition zone; High-speed railway; Finite element method; Track stiffness;

    Sammanfattning : Transition zones are changes in the track structure, detected by an abrupt deviationin track stiffness and/or differential settlements. One inevitable transition zone is thebridge approach. This study has investigated in this transition zone, adapted for highspeed,ballastless track. LÄS MER
