    Sammanfattning : In the past decade, accessing information has become easier than ever, leading to a rapid growth in popularity of social media, online gaming, and multimedia broadcast systems. These and other services put pressure on the Internet service providers to support high-speed Internet connections and motivate the need for faster communication systems. LÄS MER

  2. 22. Modelling Approaches to Molecular Systems Biology

    Författare :David Fange; Måns Ehrenberg; Johan Elf; Terence Hwa; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stochastic reaction-diffuion kinetics; antibiotic drugs; efflux pumps; amino acid biosynthesis; Min-system; rRNA operon; transcription; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Implementation and analysis of mathematical models can serve as a powerful tool in understanding how intracellular processes in bacteria affect the bacterial phenotype. In this thesis I have implemented and analysed models of a number of different parts of the bacterium E. coli in order to understand these types of connections. LÄS MER

  3. 23. Housing, Banking and the Macro Economy

    Författare :Rachatar Nilavongse; Mikael Bask; Nils Gottfries; Jesper Lindé; Uppsala universitet; []
    Nyckelord :House price expectations; Debt default; Boom-bust cycles; Monetary policy; Inflation; Welfare analysis; Credit supply disruptions; Working capital; DSGE models; Economics; Nationalekonomi;

    Sammanfattning : Essay 1: Expectation-Driven House Prices, Debt Default and Inflation DynamicsWe contribute to the literature on dynamic stochastic general equilibrium (DSGE) models with housing collateral by including shocks to house price expectations. We also incorporate endogenous mortgage defaults that are rarely included in DSGE models with housing collateral. LÄS MER

  4. 24. Linking plant population dynamics to the local environment and forest succession

    Författare :Johan Petter Dahlgren; Johan Ehrlén; Ove Eriksson; Mark Rees; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Actaea spicata; Forest herbs; Forest succession; Integral projection model; Plant demography; Plant phenology; Population dynamics; Pre-dispersal seed predation; Seed mass; Soil potassium; Specific leaf area; Terrestrial ecology; Terrestisk ekologi; Plant Ecology; växtekologi;

    Sammanfattning : Linking environmental variation to population dynamics is necessary to understand and predict how the environment influences species abundances and distributions. I used demographic, environmental and trait data of forest herbs to study effects of spatial variation in environmental factors on populations as well as environmental change in terms of effects of forest succession on field layer plants.

  5. 25. Life histories and population dynamics

    Författare :Annie Jonsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : During the last decades there has been a growing interest and attention to random variation in population densities and their causes. It has been shown that even in constant environments (deterministic population growth) the dynamics of populations can display random like behaviour depending on parameter values. LÄS MER
