1. 1. Propagation of Chaos for Kac-like Particle Systems

   Författare :Dawan Mustafa; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Master equations; chaotic densities; kinetic equations; propagation of chaos; Kac model; thermostatted master equation; Boltzmann equation; BGK equation; quenched process; uniform distribution; spectral gap; approximation process; kinetic equations;

   Sammanfattning : This thesis concerns various aspects of the Kac model. The Kac model is a Markov jump process for a particle system where the total kinetic energy of the system is conserved. This particle model is connected to a limiting equation, describing the evolution of a one-particle density, when the numbers of particles tends to infinity. LÄS MER

3. 2. Neutron Multiplicity Counting with the Analysis of Continuous Detector Signals

   Författare :Lajos Nagy; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kolmogorov equation; fissile material assay; nuclear safeguards; fission chamber; neutron multiplicity counting; master equation;

   Sammanfattning : Neutron multiplicity counting is a non-destructive assay method for determining the mass of fissile materials (primarily plutonium) using the measured values of the singles, doubles and triples detection rates. Traditionally, the detection rates are obtained from the counting statistics of neutron detectors. LÄS MER

4. 3. Numerical methods for the chemical master equation

   Författare :Stefan Engblom; Per Lötstedt; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

   Sammanfattning : The numerical solution of chemical reactions described at the meso-scale is the topic of this thesis. This description, the master equation of chemical reactions, is an accurate model of reactions where stochastic effects are crucial for explaining certain effects observed in real life. LÄS MER

7. 5. Numerical Methods for Stochastic Modeling of Genes and Proteins

   Författare :Paul Sjöberg; Per Lötstedt; Måns Ehrenberg; Achim Schroll; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; master equation; Fokker-Planck equation; stochastic models; biochemical reaction networks; Scientific Computing; Beräkningsvetenskap;

   Sammanfattning : 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. LÄS MER
