  2. 1. Methods for Simulation and Characterization of Nonlinear Mechanical Structures

    Author : Martin Magnevall; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear dynamics; nonlinear parameter estimation; harmonic balance; reverse-path; zero-memory nonlinear systems; hysteretic nonlinearities; dry-friction; geometric nonlinearities;

    Abstract : Trial and error and the use of highly time-consuming methods are often necessary for modeling, simulating and characterizing nonlinear dynamical systems. However, for the rather common special case when a nonlinear system has linear relations between many of its degrees of freedom there are particularly interesting opportunities for more efficient approaches.

  4. 2. Spin transfer torques and spin dynamics in point contacts and spin-flop tunnel junctions

    Author : Alexander Konovalenko; Vladislav Korenivski; David W. Abraham; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spin dynamics; spin transfer torques; point contacts; magnetization dynamics; Physics; Fysik;

    Abstract : The first part of this thesis is an experimental study of the spin-dependent transport in magnetic point contacts. Nano-contacts are produced micromechanically, by bringing a sharpened non-magnetic (N) tip into contact with a ferromagnetic (F) film. READ MORE
