  1. 26. Sounds Unheard of: Evolutionary algorithms as creative tools for the contemporary composer

    Författare :Palle Dahlstedt; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; evolutionary algorithms; interactive evolution; music composition; sound synthesis; non-linear dynamics; music composition;

    Sammanfattning : Evolutionary algorithms are studied as tools for generating novel musical material in the form of musical scores and synthesized sounds. The choice of genetic representation defines a space of potential music. This space is explored using evolutionary algorithms, in search of useful musical material. LÄS MER

  3. 27. Modelling, Simulation and Experimental Investigation of a Rammer Compactor Machine

    Författare :Anders Jönsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Compaction; Non-linear Dynamics; Theoretical Modelling; Numerical Simulation; Experimental Verification; Complete Approach;

    Sammanfattning : This licentiate thesis considers the modelling, simulation and experimental investigation of a rammer compactor machine. The purpose is to develop an efficient and verified method for simulation of rammer compactor machines to be used in the product development process. LÄS MER

  4. 28. Momentum-space dynamics of runaway electrons in plasmas

    Författare :Adam Stahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; synchrotron radiation; tokamak; critical electric field; non-linear collision operator; slide-away; runaway electrons; fusion-plasma physics;

    Sammanfattning : Fast electrons in a plasma experience a friction force that decreases with increasing particle speed, and may therefore be continuously accelerated by sufficiently strong electric fields. These so-called runaway electrons may quickly reach relativistic speeds. LÄS MER

  5. 29. Linear, Non-Linear, and Synchronizing Spin Wave Modes in Spin Hall Nano-Oscillators

    Författare :Hamid Mazraati; Johan Åkerman; Dario Arena; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spin Hall effect; spin Hall nano-oscillators; threshold current; microwave; spin wave; synchronization; Fysik; Physics;

    Sammanfattning : Spin Hall nano-oscillators (SHNOs) are nanoscale spintronic devices that generate microwave signals with highly tunable frequency. This thesis focuses on improving the signal quality of nanoconstriction-based SHNOs and also on developing a better understanding of their magnetization dynamics. LÄS MER

  7. 30. Nonlinear Optics Studies on the MAX IV Storage Rings

    Författare :David K Olsson; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; accelerator physics; synchrotron; storage ring; magnetic optics; non-linear optics; characterisation; optimisation;

    Sammanfattning : The MAX IV Laboratory in Lund, Sweden, houses two electron storage rings operating at the energies 1.5, and 3 GeV. Both of these produce high-brilliance synchrotron radiation for beamline users. While the 1. LÄS MER
