  1. 1. Multi-Timescale Modelling of Ethernet Traffic

    Författare :Patrik Carlsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ethernet Traffic Model; Multi-Timescale; Multifractal; Bit Rate; Moments; Fluid Flow Analysis; Model Matching; Measurement;

    Sammanfattning : Ethernet is one of the most common link layer technologies, used in local area networks, wireless networks and wide area networks. There is however a lack of traffic models for Ethernet that is usable in performance analysis. In this thesis we describe an Ethernet traffic model. LÄS MER

  2. 2. Geomorphology and environmental dynamics in Save River delta, Mozambique : A cross-timescale perspective

    Författare :Elidio Massuanganhe; Lars-Ove Westerberg; Robert Marchant; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Save River delta; deltaic wetlands; biogeomorphology; climate change; landscape evolution; coastal management; socio-ecological systems; Physical Geography; naturgeografi;

    Sammanfattning : Long-term perspectives on the evolution of river deltas have provided useful knowledge capable of responding to pending questions related to the ongoing climate and environmental changes. Increasing utilization pressure on delta environments has necessitated increased attention to protect the socio-economic and ecological values. LÄS MER

  3. 3. Volumetric Analysis in Mechanical Behaviour and Physical Ageing of Polymers

    Författare :Mats Delin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ageing rate; Gr neisen parameter; bulk modulus; KAHR model; dilatometry; Poisson s ratio; timescale; physical ageing; dynamic mechanical properties; stress relaxation; volume changes; creep; Doolittle s equation;

    Sammanfattning : Volumetric changes associated with the deformation of ideal elastic solids depends on elastic constants of the solid and applied strain. Their magnitude is easily determined from the corresponding Poisson's ratios. LÄS MER

  4. 4. Light-Matter Interaction on the Attosecond Timescale

    Författare :Marcus Dahlström; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2011:Dahlström; Temporal characterization; Two-color harmonic generation; High-order harmonic generation; Attosecond pulse trains; Electron wave packets; Two-photon ionization; Coherent control;

    Sammanfattning : Attosecond science refers to physical processes that occur on the natural timescale of electron motion in atomic and molecular systems. Attosecond time resolution can be obtained experimentally through a process called high-order harmonic generation where sharp attosecond pulses are formed in the time domain. LÄS MER

  5. 5. Probing Electron Correlation on the Attosecond Timescale

    Författare :Diego Guenot; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Guénot;

    Sammanfattning : This thesis describes how photoemission stimulated by an attosecond pulse train (APT) can be used to extract information on electron correlation in simple quantum systems such as atoms. The emission of the electron by an APT induces a reorganization of the electrons remaining in the ion core. LÄS MER
