  2. 2. Om vikten av att i automationsprocessen integrera handens och hjärnans arbete

    Författare :Bertil Gustafsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; SOCIAL SCIENCES; Tacit knowledge; Small scale production; Operator´s computer; Cross-functional work teams; Robot arc welding; Decentralised work organisation;

    Sammanfattning : This licentiate report attempts to add to our knowledge of how the competence of skilled workers can be incorporated into modern manufacturing systems, without depriving them of the status that they had earned through their previous specialised skills and knowledge. The work is concentrated on establishing a theoretical basis for a model of how the computer can support this work: the Operator's Computer approach has been applied in three case-studies, thus taking it over the threshold into the Swedish engineering industry.

  3. 3. Evaluation of attenuation and scatter corrections in lung and brain SPECT

    Författare :Agnetha Gustafsson; Bertil Axelsson; Göteborgs universitet Avdelningen för radiofysik Department of Radiations Physics; []
    Nyckelord :SPECT; attenuation; scatter; detectability; Monte Carlo simulation; MEDICINE; MEDICIN;

    Sammanfattning : Single Photon Emission Computed Tomography (SPECT) is used to image functional processes in the human body. The image process is affected by physical effects such as attenuation, scatter, spatial resolution and statistical noise. LÄS MER

  4. 4. Numerical simulation of kinetic effects in ionospheric plasma

    Författare :Bengt Eliasson; Bertil Gustafsson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

    Sammanfattning : In this thesis, we study numerically the one-dimensional Vlasov equation for a plasma consisting of electrons and infinitely heavy ions. This partial differential equation describes the evolution of the distribution function of particles in the two-dimensional phase space (x,v). LÄS MER

  5. 5. Numerical Vlasov–Maxwell Modelling of Space Plasma

    Författare :Bengt Eliasson; Bertil Gustafsson; Bo Thidé; Anders Bondeson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Vlasov equation; Maxwell equation; Fourier method; outflow boundary; domain decomposition; Numerical Analysis; Numerisk analys;

    Sammanfattning : The Vlasov equation describes the evolution of the distribution function of particles in phase space (x,v), where the particles interact with long-range forces, but where shortrange "collisional" forces are neglected. A space plasma consists of low-mass electrically charged particles, and therefore the most important long-range forces acting in the plasma are the Lorentz forces created by electromagnetic fields.
