  1. 16. Structural and evolutionary aspects of stochastic processes

    Författare :Olof Görnerup; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Proto-cells.; Emergence; Self-organization; Coarse graining; Model reduction; Hierarchical dynamics; Pre-biotic evolution; Complexity;

    Sammanfattning : Stochastic processes constitute a broad class of objects of central importance in complex systems. The main structural aspect of stochastic processes that is treated in this thesis is their hierarchical dynamics. LÄS MER

  3. 17. A Field of Possibilities: Designing and Playing Digital Musical Instruments

    Författare :Per Anders Nilsson; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Digital musical instruments; improvisation; experimental music; jazz; free improvisation; music of sounds; computer music; interaction design; design time – play time; practicing; play; game and sports; self-organization; rules; affordances; predeterminations; artistic research;

    Sammanfattning : This thesis focuses on a set of digital musical instruments I have designed and developed with ensemble improvisation in mind. The intention is not to create a universal improvisational instrument, but rather to create a set of instruments which each realize one musical idea. LÄS MER

  4. 18. X-ray Absorption Spectroscopy on Nano-Magnet Arrays and Thin Films : Magnetism and Structure

    Författare :Andreas Persson; Dimitri Arvanitis; Cormac McGuinness; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; self organization; nano-magnet; xmcd; exafs; peem; magnetism; Surfaces and interfaces; Ytor och mellanytor; Magnetism; Magnetism; Materiefysik; Physics of Matter;

    Sammanfattning : The magnetic and structural properties of nano magnet arrays and ferromagnetic thin films are investigated. Circular x-rays are used and extensive use is made in this Thesis of the X-ray Magnetic Circular Dichroism (XMCD) technique. By means of the XMCD magneto-optic sum rules the values of the orbital and spin moments are determined. LÄS MER

  5. 19. Information horizons in a complex world

    Författare :Martin Rosvall; Petter Minnhagen; Kim Sneppen; Vito Latora; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex systems; networks; information; communication; self-organization; network topology; agent-based modeling.; Physics; Fysik;

    Sammanfattning : The whole in a complex system is the sum of its parts, plus the interactions between the parts. Understanding social, biological, and economic systems therefore often depends on understanding their patterns of interactions---their networks. LÄS MER

  7. 20. Ion Tracks for Micro- and Nanofabrication : From Single Channels to Superhydrophobic Surfaces

    Författare :Reimar Spohr; Lars Westerberg; Lars Montelius; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ion track; single ion; real time; phase detection; conductometric cell; conductometry; electro replication; microtechnology; nanotechnology; surfactant; self organization; GMR; magnetic; sensor technology; hydrophobic; tilted texture.; Physics; Fysik; Materialvetenskap; Materials Science;

    Sammanfattning : A method is described for preset-count irradiations between 1 and 100 ions singling-out individual ions from an ion beam with more than a billion ions arriving per second. The ion tracks are etched in a conductometric system with real-time evaluation of the acquired data. The etch process can be interrupted when reaching a preset channel diameter. LÄS MER
