  4. 2. Case studies in omniparametric simulation

    Author : Fredrik Lundin; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; growth model; Ising model; Markov chain; omnithermal simulation; omniparametric simulationpercolatiion; Potts model; parameter estimation; partial observations; random cluster model; Richardson model; simulation driven parameter estimation; two-type Richardson model; omnithermal simulation;

    Abstract : In the eld of particle systems and growths models simulation is an important tool. When explicit calculations are too complex or impossible to perform we may use simulations instead. We adapt a new technique here denoted omniparametric simulation, to the two-type Richardson, Ising and Potts models. READ MORE

  5. 3. A Statistical Approach to Near Dry Machining

    Author : Marina Isaksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooling; turning; carbide; lubrication.; aerospace; Near-dry-machining; ceramic; MQL;

    Abstract : To substantiate the implementation of near dry machining in such a demanding industry as the aerospace industry, it is essential to have a broad understanding about the phenomena behind near dry machining. The conditions for the aerospace industry is stated in such a way, that changes or method development of the process had to be very well founded before it could be executed. READ MORE

  6. 4. Diversification of TGF-β Signaling in Homeostasis and Disease

    Author : Michael Vanlandewijck; Aristidis Moustakas; Carl-Henrik Heldin; Steven Dooley; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-β; signaling; SIK; EMT; polarity; Notch; ALK5; p21; growth arrest; Smurf; Smad7; receptor; SNF1LK; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Abstract : With the dawn of metazoans, the ability of cells to communicate with each other became of paramount importance in maintaining tissue homeostasis. The transforming growth factor β (TGF-β) signaling pathway, which plays important roles during embryogenesis and in the adult organism, signals via a heterodimeric receptor complex consisting of two type II and two type I receptors.

  7. 5. Epidemic models with contact tracing: manual and digital tracing

    Author : Dongni Zhang; Tom Britton; Peter Olofsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; matematisk statistik; Mathematical Statistics;

    Abstract : Contact tracing is an effective measure for controlling the epidemic spreading. In this thesis, we consider a Markovian SIR epidemic model in a homogeneous community with a constant rate of diagnosis (testing) and investigate the preventive effect of contact tracing. READ MORE
