  2. 2. Fibre Orientation Modelling Applied to Contracting Flows Related to Papermaking

    University dissertation from Stockholm : KTH

    Author : Marko Hyensjö; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fokker-Planck; fibre orientation; shear flow; fibre suspension; planar contraction; headbox; turbulent flow; TECHNOLOGY Engineering mechanics Other engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik Övrig teknisk mekanik;

    Abstract : The main goal of this work was to develop numerical models for studying the behaviour of fibres in an accelerated flow. This is of special interest for e.g. papermaking. READ MORE

  3. 3. Numerical Methods for Stochastic Modeling of Genes and Proteins

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Paul Sjöberg; Uppsala universitet.; Uppsala universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; master equation; Fokker-Planck equation; stochastic models; biochemical reaction networks; Scientific Computing; Beräkningsvetenskap;

    Abstract : Stochastic models of biochemical reaction networks are used for understanding the properties of molecular regulatory circuits in living cells. The state of the cell is defined by the number of copies of each molecular species in the model. READ MORE

  4. 4. Kinetic modelling of runaway in plasmas

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ola Embréus; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fokker-Planck equation; synchrotron radiation; plasma; runaway; bremsstrahlung; Boltzmann equation;

    Abstract : The phenomenon of runaway occurs in plasmas in the presence of a strong electric field, which overcomes the collisional friction acting on the charged particles moving through the plasma. A subpopulation of particles can then be accelerated to energies significantly higher than the thermal energy. READ MORE

  5. 5. Kinetic modelling of runaways in plasmas

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Ola Embréus; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; runaway; Fokker-Planck equation; tokamak; Boltzmann equation; positrons; bremsstrahlung; plasma; synchrotron radiation;

    Abstract : The phenomenon of runaway occurs in plasmas in the presence of a strong electric field, when the accelerating force overcomes the collisional friction acting on the charged particles moving through the plasma. Electron runaway is observed in both laboratory and space plasmas, and is of great importance in fusion-energy research, where the energetic electrons can damage the plasma-facing components of fusion reactors.
