1. 11. Visualization and mesoscopic simulation in systems biology

   Författare :Martin Falk; Thomas Ertl; Germany University of Stuttgart Visualization Research Center; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Visualization; GPGPU; Simulation; Systems Biology; Model Development; Signal Transduction;

   Sammanfattning : Biological cells appear everywhere on earth. They might live on their own as unicellular organism, like bacteria, or might form complex organisms consisting of several thousands or millions of cells. Despite their small size of only a few micrometers, they are complex little miracles. LÄS MER

3. 12. Barycentric Markov processes and stability of stochastic integrators

   Författare :Philip Kennerberg; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geometric probability; dirichlet processes; Markov processes; stochastic integration; interacting particle systems;

   Sammanfattning : This thesis consists of four papers that broadly concerns two dierent topics. The rsttopic is so-called barycentric Markov processes. By a barycentric Markov process wemean a process that consists of a point/particle system evolving in (discrete) time,whose evolution depends in some way on the mean value of the current points in thesystem.

4. 13. Collective behavior of disordered magnetic systems

   Författare :Tomas Jonsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Sammanfattning : Magnetic properties of disordered and frustrated magnets have been experimentally investigated. The magnetic systems in focus in this work are spin-glasses and frozen ferrofluids (suspensions of nano-sized magnetic particles). LÄS MER

5. 14. Dark Matter Phenomenology in Astrophysical Systems

   Författare :Stefan Clementz; Mattias Blennow; Kai Schmidt-Hoberg; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

   Sammanfattning : There is now a great deal of evidence in support of the existence of a large amount of unseen gravitational mass, commonly called dark matter, from observations in astrophysical systems of sizes ranging from that of dwarf galaxies to the scale of the entire Universe. One of the most promising explanations for this unseen mass is that it consists of a species of unobserved elementary particles. LÄS MER

7. 15. Numerical study of dynamics of mass-emitting particles in multi-phase flow

   Författare :Zeinab Moradi Nour; Minh Do-Quang; Fredrik Lundell; Gustav Amberg; Hans Kuipers; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particles with outflow; lattice Boltzmann method; particle interaction; liquid-gas-solid systems; sedimentation; shear flow; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Suspended particles can be found in wide range of industrial applications such as food industry, mining industry and energy conversion processes. Depending on flow cases which particles are involved, different dynamics and motions are expected from suspended particles. LÄS MER
