  3. 2. On Perfect Simulation of Markovian Queueing Networks with Blocking

    Författare :Dan Mattsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Markov chain; Monte Carlo methods; Propp-Wilson algorithm; perfect simulation; queueing theory; Jackson networks; birth and death processes; Jackson networks;

    Sammanfattning : Perfect simulation of a class of Markovian queueing networks with finite buffers is examined in this monograph. The network processes defined are modelled by restricted multivariate birth and death processes with intensities depending on a random environment. The random environments are mainly a set of independent onoff processes. LÄS MER

  4. 3. Aspects of Modeling Fraud Prevention of Online Financial Services

    Författare :Gorton Dan; Lars-Göran Mattsson; Simin Nadjm-Tehrani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Online banking; fraud; incident response; metrics; incident response tree IRT ; value at risk VaR ; simulation; Transportvetenskap; Transport Science;

    Sammanfattning : Banking and online financial services are part of our critical infrastructure. As such, they comprise an Achilles heel in society and need to be protected accordingly. The last ten years have seen a steady shift from traditional show-off hacking towards cybercrime with great economic consequences for society. LÄS MER

  5. 4. Development of techniques for measurements of shock wave response and moisture content in granite

    Författare :Dan Tilert; Lars Mattsson; Mikael Sjödahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : For measuring small, fast deformations on a micrometre scale optical methods are common. Various forms of interferometry are available, and holography is another possibility. However, if there are complications such as limited space and hazardous environments special demands arise. LÄS MER
