  2. 11. Linear and Non-linear Deformations of Stochastic Processes

    Author : Gustaf Strandell; Maciej Klimek; Richard Aron; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Riesz bases and frames; Weakly stationary stochastic processes; Set-valued analysis; Matematisk analys; Mathematical analysis; Analys;

    Abstract : This thesis consists of three papers on the following topics in functional analysis and probability theory: Riesz bases and frames, weakly stationary stochastic processes and analysis of set-valued stochastic processes. In the first paper we investigate Uniformly Bounded Linearly Stationary stochastic processes from the point of view of the theory of Riesz bases. READ MORE

  4. 12. Groundwater Recharge in Crystalline Bedrock : Processes, Estimation, and Modelling

    Author : Niclas Bockgård; Sven Halldin; Allan Rodhe; Auli Niemi; Lars O. Ericsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; groundwater recharge; bedrock; crystalline rocks; tracers; CFC; surface loading; loading efficiency; barometric effect; heterogeneity; stochastic modelling; Hydrologi; Hydrology; Hydrologi;

    Abstract : Kunskap om grundvattenbildningen är nödvändig för att man ska kunna förutsäga konsekvenserna av grundvattenuttag och underjordsbyggande. Grundvattenbildningen i berggrunden är dock svår att uppskatta. READ MORE

  5. 13. The stochastic nature of intracellular control circuits

    Author : Johan Paulsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Stochastic; mesoscopic; noise; gene; plasmid; metabolic; regulation; control; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Chemical reactions are probabilistic by nature, causing random fluctuations inconcentrations to emerge spontaneously. In conventional (macroscopic) kinetics this internal noise is ignored under the assumption that average copy numbers are so high that fluctuations are negligible in comparison. READ MORE

  6. 14. A Serendipitous Journey through Stochastic Processes

    Author : Ludovico Theo Giorgini; John Scott Wettlaufer; Valerio Lucarini; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : In this licentiate thesis I will present some new insights in different problems in the field of stochastic processes. A stochastic resonance system is studied using path integral techniques, originally developed in quantum field theory, to recover the optimal means through which noise self-organises before a rare transition from one potential well to the other.

  7. 15. A Class of Renewal Processes in Random Environments

    Author : David Svensson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; point process; renewal process; random environment; coupling; regeneration; failure rate; Poisson embedding; asymptotics; stochastic domination; stochastic monotonicity; renewal process;

    Abstract : This paper deals with a generalization of the class of renewal processes with absolutely continuous life length distribution, obtained by allowing a random environment to modulate the stochastic intensity of the renewal process. The random environment is a birth and death process with a finite state space. READ MORE
