  2. 1. Nonlinear Beam Physics

    Author : Benjamin Folsom; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nonlinear dynamics; Beam dynamics; Accelerator Physics; space charge; Accelerator magnets; simulations multi-particle dynamics;

    Abstract : A condensed treatment of conventional beam physics (both linear and nonlinear) is given for the non-expert; this constitutes a minimum knowhow for constructing simulations of rudimentary beamlines. The criteria for an ideal nonlinear charged-particle simulation algorithm are then presented, leading to the derivation of a symplectic, explicit, Lorentz-covariant integrator. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mass sensing; graphene; stochastic differential equations; diffusion; carbon nanotubes; resonators; nanoelectromechanical systems; equations of motion; nonlinear dynamics; dissipation; Fokker-Planck equation; noise; nonequilibrium dynamics;

    Abstract : The emergence of nanoelectromechanical systems has enabled the development of sensors capable of detecting mass, charge, force, position, and spin with an unprecedented precision. In particular, the low mass, high resonant frequency, and high quality factor of carbon nanomechanical resonators make them ideal for the creation of a high sensitivity mass sensor. READ MORE

    Abstract : This work is a study of nonlinear phenomena in vertically stacked pairs of magnetic vortices. New dynamic regimes are uncovered with a decrease in the inter-vortex separation to below the lateral vortex-core size. READ MORE

  7. 5. Reduced Order Modeling and Substructuring : Applications in Nonlinear Structural Dynamics

    Author : Linus Andersson; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reduced order modeling; Substructuring; Nonlinear dynamics; Geometrically nonlinear; Modal derivatives; Blast loading; Soft-body impact; Glass structures;

    Abstract : A structural design process typically involves various load cases for which a sufficient load-bearing capacity must be demonstrated. In addition to static load cases, a verification of dynamic loads, such as blast and impact loading, may be required. READ MORE
