  2. 11. Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy flavour quarks with the ATLAS experiment

    Author : Anna Shcherbakova; Sara Strandberg; Chad Finley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; b-tagging; calibration; Dark Matter; simplified model; Physics; fysik; High Energy Physics;

    Abstract : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS detector is a general-purpose particle detector at the LHC, designed to cover a wide range of physics measurements. READ MORE

  4. 12. Methods for Optimal Model Fitting and Sensor Calibration

    Author : Erik Ask; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Model Fitting; Sensor Networks; Computer Vision; Polynomial Equations; Action Matrix Methods;

    Abstract : The problem of fitting models to measured data has been studied extensively, not least in the field of computer vision. A central problem in this field is the difficulty in reliably find corresponding structures and points in different images, resulting in outlier data. READ MORE

  5. 13. Calibration Adjustment for Nonresponse in Sample Surveys

    Author : Bernardo João Rota; Thomas Laitila; Sune Karlsson; Risto Lehtonen; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Auxiliary variables; Calibration; Nonresponse; principal com-ponents; regression estimator; response probability; survey sampling; two-step estimator; variance estimator; weighting; Statistics; Statistik;

    Abstract : In this thesis, we discuss calibration estimation in the presence of nonresponse with a focus on the linear calibration estimator and the propensity calibration estimator, along with the use of different levels of auxiliary information, that is, sample and population levels. This is a fourpapers- based thesis, two of which discuss estimation in two steps. READ MORE

  6. 14. Biotic Ligand model : A tool for risk assessment of metals in Scandinavian fresh waters?

    Author : Sabina Hoppe; Magnus Breitholtz; Jon-Petter Gustafsson; Karel De Schamphelaere; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BLM; Soft freshwaters; Sweden; Cu; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Products from iron and copper mining are among Sweden’s top exports. However, as the metals are excavated, they often end up in the aquatic environment where they can cause toxicity. READ MORE

  7. 15. ATLAS Calorimetry : Hadronic Calibration Studies

    Author : Karl-Johan Grahn; Bengt Lund-Jensen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : The ATLAS experiment -- situated at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) in Geneva -- is on schedule to take its first collision data in 2009. Physics topics include finding the Higgs boson, heavy quark physics, and looking for extensions of the standard model such as supersymmetry. READ MORE
