    • New experimental techniques to study the adhesion to various solid surfaces of hydrate-relevant droplets and particles 

      Dahl, Maren Andrea (Master thesis, 2010-10-01)
      Hydrate plugging is a substantial problem in the oil and gas industry, both economically, environmentally and safety wise. Plugging may occur as a result of agglomeration of hydrate particles, deposition of hydrates on the ...

    • On automatic data processing and well-test analysis in real-time reservoir management applications 

      Olsen, Stig (Doctoral thesis, 2011-06-30)

    • Particle–wave discrimination in Poisson spot experiments 

      Reisinger, Thomas; Bracco, Gianangelo; Holst, Bodil (Peer reviewed; Journal article, 2011)
      Matter–wave interferometry has been used extensively over the last few years to demonstrate the quantum-mechanical wave nature of increasingly larger and more massive particles. We have recently suggested the use of the ...

    • Phase transitions in non-equilibrium dynamical systems 

      Horvát, Szabolcs (Doctoral thesis, 2010-12-09)
      This work is a summary of three papers (references [5, 14, 24]), which deal with modelling the hadronization and freeze-out in heavy ion collisions. There is evidence that this is a non-equilibrium process, and therefore ...

    • Poisson’s spot with molecules 

      Reisinger, Thomas; Patel, Amil A.; Reingruber, Herbert; Fladischer, Katrin; Ernst, Wolfgang E.; Bracco, Gianangelo; Smith, Henry I.; Holst, Bodil (Peer reviewed; Journal article, 2009)
      In the Poisson-spot experiment, waves emanating from a source are blocked by a circular obstacle. Due to their positive on-axis interference an image of the source the Poisson spot is observed within the geometrical shadow ...

    • Production of pions, kaons and protons in pp collisions at s=900 GeV with ALICE at the LHC 

      The ALICE Collaboration; Aamodt, K.; Abel, N.; Abeysekara, U.; Quintana, A. Abrahantes; Alme, Johan; Helstrup, Håvard (Peer reviewed; Journal article, 2011-06-15)
      The production of π +, π −, K+, K−, p, and p at mid-rapidity has been measured in proton-proton collisions at s=900 GeV with the ALICE detector. Particle identification is performed using the specific energy loss in the ...

    • Recreating the top quark: Commissioning and monitoring of the ATLAS Inner Detector and search for New Physics with heavy particles. 

      Tonoyan, Arshak (Doctoral thesis, 2012-02-03)
      The ATLAS (A Toroidal Lhc ApparatuS) experiment is one of the two general purpose experiments at the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research. The LHC is a proton-proton and ion-ion ...

    • Search for single top quark production via contact interactions at LEP2 

      The DELPHI Collaboration; Abdallah, Jalal; Abreu, P.; Adam, W.; Adzic, P.; Albrecht, T.; Eigen, Gerald (Peer reviewed; Journal article, 2011-02-15)
      Single top quark production via four-fermion contact interactions associated to flavour-changing neutral currents was searched for in data taken by the DELPHI detector at LEP2. The data were accumulated at centre-ofmass ...

    • Space and Energy Distribution of Dark Matter 

      Blitzner, Åsmund (Master thesis, 2011-11-17)
      I start by an introduction to the notion of, and motivation for, Dark Matter, as well as a short motivation for supersymmetry, the theoretical framework usually examined when looking for places that dark matter may hide. ...

    • Strange particle production in proton–proton collisions at s=09 with ALICE at the LHC The ALICE Collaboration 

      The ALICE Collaboration; Aamodt, K.; Quintana, A. Abrahantes; Adamová, D.; Adare, A.M.; Richter, Matthias (Peer reviewed; Journal article, 2011-03-30)
      The production of mesons containing strange quarks (, φ) and both singly and doubly strange baryons (, , and ) are measured at mid-rapidity in pp collisions at s = 0.9 TeV with the ALICE experiment at the LHC. The results ...

    • Studies of the performance of the ATLAS detector using cosmic-ray muons 

      ATLAS, Collaboration; Aad, Georges; Abbott, Brad; Abdallah, Jalal; Abdelalim, A. A.; Buanes, Trygve (Peer reviewed; Journal article, 2011-03-29)
      Muons from cosmic-ray interactions in the atmosphere provide a high-statistics source of particles that can be used to study the performance and calibration of the ATLAS detector. Cosmic-ray muons can penetrate to the ...

    • A study of selected problems related to accidental process fires 

      Drange, Leiv Anfin (Doctoral thesis, 2011-04-15)
      An experimental full scale characterization of a turbulent propane jet flame has been made in terms of temperatures and radiation. Sonic propane gas releases were achieved at steady pressure and near steady flow. Commercial ...

    • Tilstandsovervåkning av undervanns motordrift med lange forsyningskabler 

      Stjernberg, Stian (Master thesis, 2010-06-01)
      Hensikten med denne mastergradsoppgaven er å sette opp et testanlegg bestående av forsyningskabel og induksjonsmotor for å teste om tilstandsovervåkning kan utføres ved strømanalyse av lange forsyningskabler. Det skal ...

    • Two Higgs Doublets plus One Dark Matter Singlet 

      Tochin, Alexey (Master thesis, 2010-08-01)
      In this thesis an extension of the 2HDM (see chapter 1) is explored. The extension admits an extra inert singlet which is a dark matter candidate. Before the exploration a large part of the thesis (chapter 2) is an overview ...
