  1. 1. Perturbed discrete time stochastic models

    University dissertation from Stockholm : Department of Mathematics, Stockholm University

    Author : Mikael Petersson; Stockholms universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Renewal equation; Perturbation; Asymptotic expansion; Regenerative process; Risk process; Semi-Markov process; Markov chain; Quasi-stationary distribution; Ruin probability; First hitting time; Solidarity property; matematisk statistik; Mathematical Statistics;

    Abstract : In this thesis, nonlinearly perturbed stochastic models in discrete time are considered. We give algorithms for construction of asymptotic expansions with respect to the perturbation parameter for various quantities of interest. READ MORE

  2. 2. Asymptotic Expansions for Perturbed Discrete Time Renewal Equations

    University dissertation from Department of Mathematics

    Author : Mikael Petersson; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Renewal equation; Perturbation; Asymptotic expansion; Regenerative process; Quasi-stationary distribution; Risk process; Ruin probability;

    Abstract : In this thesis we study the asymptotic behaviour of the solution of a discrete time renewal equation depending on a small perturbation parameter. In particular, we construct asymptotic expansions for the solution of the renewal equation and related quantities. READ MORE

  3. 3. Methanation of biosyngas in a fluidized bed reactor

    University dissertation from Department of Mathematics

    Author : Martin Seemann; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENERGY TECHNOLOGY; REGENERATIVE ENERGIES; GASIFICATION OF WOOD; FLUIDIZED BED PROCESSES; CHEMICAL ENGINEERING; FUEL TECHNOLOGY; ALTERNATIVE ENERGIES; METHANATION OF HYDROGEN-CARBONMONOXIDE MIXTURES; SYNTHETIC FUELS; NATURAL GAS; BIOGASES;

    Abstract : Rising prices for fossil fuels and concerns over the climate change increase the interest in renewable energies. Synthetic natural gas (SNG) can be an option, filling the request for alternatives in the transportation sector, where the dependence on the oil is very strong. READ MORE

  4. 4. Studies on glycosphingolipids in regenerative medicine

    University dissertation from Göteborg : University of Gothenburg

    Author : Angela Barone; Göteborgs universitet.; Gothenburg University.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glycosphingolipids; human embryonic stem cells; Cell surface markers; porcine heart valves; xenotransplantation; regenerative medicinr;

    Abstract : Regenerative medicine, including stem cell based therapies and xenotransplantation, is a new and developing field that aims to restore normal function in end stage cell/organ failure. However, in therapeutic settings involving transfer of cells with a different genetic background, these cells will expose the recipient to non-self cell surface antigenic determinants that may evoke an immune response and subsequent graft damage.

  5. 5. Low-Power Clocking and Circuit Techniques for Leakage and Process Variation Compensation

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Martin Hansson; Linköpings universitet.; Linköpings universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-power; resonant clocking; multi-GHz; CMOS; leakage tolerance; low-leakage techniques; process variation; process variation compensation; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronik;

    Abstract : Over the last four decades the integrated circuit industry has evolved in a tremendous pace. This success has been driven by the scaling of device sizes leading to higher and higher integration capability, which have enabled more functionality and higher performance. READ MORE
