  1. 6. Statistical Modelling of Cell Cycle Dynamics Analysis and Interpretation of BrdUrd DNA FCM-Derived Data

    Författare :Sara Larsson Lönn; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; G2 phase duration; DNA replication; flow cytometry; Natural science; Naturvetenskap; S phase duration; DNA distribution; branching processes; cell cycle kinetics;

    Sammanfattning : It it of great importance to increase the knowledge of various cell cycle kinetic parameters and the objective of this thesis is to use stochastic models to interpret Bromodeoxyuridine (BrdUrd) DNA Flow Cytometry (FCM) derived data in order to estimate such parameters. The cell cycle is the process of growth and division that is essential for an organism to increase in size. LÄS MER

  3. 7. Some Extensions of Poincaré-Bendixson Theory Applied to a Resonant Converter

    Författare :Jan Melin; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datalogi; numerisk analys; system; kontroll; numerical analysis; systems; control; Naturvetenskap; Computer science; Natural science; Poincaré-Bendixson Theory; Limit Cycles; Resonant Converter; Distributions; Piecewise Linear Systems;

    Sammanfattning : In this thesis existence and uniqueness of limit cycles are shown for a resonant converter, by extending Poincaré-Bendixson theory to non-smooth vector fields. We discuss relevant control theory and the role of simulations... LÄS MER

  4. 8. A Catalytic and Mechanistic Investigation of Palladium-Phosphine Catalysed Aqueous Hydroxycarbonylation. Steric and Electronic Properties of the Ligands

    Författare :Adriana Ionescu; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oorganisk kemi; Inorganic chemistry; Naturvetenskap; Natural science; Isomerisation of hydroxyalkenes; Mechanism; Regioselectivity; Steric and electronic properties; Hydroxycarbonylation of styrene; Water-soluble phosphines; Palladium; Aqueous catalysis;

    Sammanfattning : The steric and electronic properties of eight water-soluble phosphines (1-8) were investigated by different methods. Phosphines 1-6 were tested as ligands in palladium catalysed hydroxycarbonylation of styrene. LÄS MER

  5. 9. Evaluating credal set theory as a belief framework in high-level information fusion for automated decision-making

    Författare :Alexander Karlsson; Sten F. Andler; Ronnie Johansson; Lars Karlsson; Galina Rogova; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; High-level information fusion; belief framework; credal set theory; Bayesian theory; Computer science; Datavetenskap; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Datalogi; Computer and Systems Science; Teknik;

    Sammanfattning : High-level information fusion is a research field in which methods for achieving an overall understanding of the current situation in an environment of interest are studied. The ultimate goal of these methods is to provide effective decision-support for human or automated decision-making. LÄS MER

  7. 10. Charge transport modulation in organic electronic diodes

    Författare :Fredrik Lars Emil Jakobsson; Magnus Berggren; Xavier Crispin; Paul W. M. Blom; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; switch device; memory; photochromic; trapping; resistance switching; Physics; Fysik;

    Sammanfattning : Since the discovery of conducting polymers three decades ago the field of organic electronics has evolved rapidly. Organic light emitting diodes have already reached the consumer market, while organic solar cells and transistors are rapidly maturing. One of the great benefits with this class of materials is that they can be processed from solution. LÄS MER
