  1. 1. SECOND-ORDER DIVERGENCE-FREE FEM FOR MAGNETOHYDRODYNAMICS USING LAGRANGE POLYNOMIALS

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Erik Björklund; Peter Mårtensson; Noah Waltman; [2023]
    Keywords : ;

    Abstract : AbstractMaxwell’s laws state that the divergence of a magnetic field always remains zero. In thecontinuous setting this is true for the magnetohydrodynamics equations. However, in thediscrete setting, the solution does not always remain divergence-free. READ MORE

  3. 2. Localized and extended states in finite-sized mosaic Wannier-Stark lattices

    University essay from KTH/Tillämpad fysik

    Author : Emrah Tortumlu; [2023]
    Keywords : Applied Physics; Condensed matter physics; quantum technology; quantum nanophotonics; localization; mobility edge; phase transition; Tillämpad Fysik; Kondenserade materiens fysik; kvantteknologi; kvantnanofotonik; lokalisering; fasövergång;

    Abstract : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

  4. 3. Impact of Residual Stress on the Warm Pre-Stressing Effect

    University essay from KTH/Hållfasthetslära

    Author : Emil Danielsson; [2023]
    Keywords : Warm Pre-Stressing effect; Residual stress; Cleavage fracture; Ferritic Steel; Fracture mechanics; Varm förspänning; Restspänningar; Klyvbrott; Brottmekanik; Ferritiskt stål;

    Abstract : Irradiation of a reactor pressure vessel (RPV) causes a shift of the ductile to brittle transition region towards higher temperature regions. In the event of a pressurized thermal shock (PTS), where the temperature drops drastically, the ductile to brittle transition region might be entered for irradiated ferritic steel. READ MORE

  5. 4. On linear Reaction-Diffusion systems and Network Controllability

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Rebecka Aulin; Felicia Hage; [2023]
    Keywords : Turing s model of morphogenesis; FDM; FEM; Controllability; Minimal Control; Least Energy Control;

    Abstract : In 1952 Alan Turing published his paper "The Chemical Basis of Morphogenesis", which described a model for how naturally occurring patterns, such as the stripes of a zebra and the spots of a leopard, can arise from a spatially homogeneous steady state through diffusion. Turing suggested that the concentration of the substances producing the patterns is determined by the reaction kinetics, how the substances interact, and diffusion. READ MORE

  6. 5. Investigating programming language support for fault-tolerance

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ismail Demirkoparan; [2023]
    Keywords : Dataflow; Fault tolerance; Data streaming; Distributed systems; Checkpointing; Logging; Lineage; Lineage stash; Arc-Lang; Apache Flink;

    Abstract : Dataflow systems have become the norm for developing data-intensive computing applications. These systems provide transparent scalability and fault tolerance. For fault tolerance, many dataflow-system adopt a snapshotting approach which persists the state of an operator once it has received a snapshot marker on all its input channels. READ MORE
