  1. 1. Hidden Markov models - Traffic modeling and subspace methods

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Sofia Andersson; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; programming; actuarial mathematics; Statistik; operationsanalys; Statistics; operations research; subspace identification; state space representation; likelihood estimation; Poissonification; traffic analysis; hidden Markov model; Markov-modulated Poisson process; programmering; aktuariematematik;

    Abstract : The main motivation for this thesis, however not the only one, is the search for models for traffic in telecommunication networks. Traffic characterization and modeling are of great importance in the analysis and dimensioning of communication systems. During the last decades we have experienced an explosive growth of our telecommunication networks. READ MORE

  2. 2. Invariant NKT cells and CD1d in HIV-1 infection

    University dissertation from Stockholm : Karolinska Institutet, Dept of Medicine, Huddinge

    Author : Sofia Andersson; Karolinska Institutet.; Karolinska Institutet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The invariant natural killer T (iNKT) cells are a subset of T lymphocytes that share characteristics of both innate and adaptive immunity. These cells are defined as T cells restricted by the lipid antigen presenting molecule CD1d and express an invariant T cell receptor (TCR) as well as classical natural killer (NK) cell markers.

  3. 3. Exocytosis in Type 2 Diabetes- Functional and genetic studies of hormone secretion

    University dissertation from Unit of Islet Cell Exocytosis

    Author : Sofia A Andersson; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 Diabetes; Insulin; Glucagon; Alpha-cells; Beta-cells; Exocytosis; Capacitance; SNARE; SNAP25; Syntaxin1A; Synaptotagmin; Munc-18 Stxbp1 ; SNP; Expression; miRNA;

    Abstract : Type 2 Diabetes (T2D) is characterized by dysregulated beta-and alpha-cell hormone secretion leading to elevated blood glucose levels. Several proteins are crucial in maintaining exocytosis of the hormone-containing granules such as Syntaxin1A (Stx1A), SNAP25, Munc-18 (Stxbp1) and the family of Synaptotagmins (Syts). READ MORE

  4. 4. Characterization of Bacterial Biofilms for Wastewater Treatment

    University dissertation from Stockholm : Kungliga Tekniska Högskolan

    Author : Sofia Andersson; KTH.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biofilm; extracellular polymeric substances; exopolysaccharides; interspecies interactions; wastewater treatment; denitrification; phosphorus removal; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi;

    Abstract : Research performed at the Division of Environmental Microbiology has over the last years resulted in the isolation of possible bacterial key-organisms with efficient nutrient removal properties (Comamonas denitrificans, Brachymonas denitrificans, Aeromonas hydrophila). Effective use of these organisms for enhanced nutrient removal in wastewater treatment applications requires the strains to be retained, to proliferate and to maintain biological activity within theprocess.
