  • Frå transistor til datamaskin 

    Tengesdal, Morten (Notater fra Universitetet i Stavanger;39, Report, 2018-04)
    Dette skrivet prøver å gi ei forståing av korleis datamaskinar er oppbygde og virkar. Ein ser også på korleis ein kan programmera mindre datamaskinar brukte til styring og overvaking av prosessar. Skrivet er laga for bruk ...

    Among others, properly designed drilling fluid is a key for a success of drilling operation. The rheology, and lubricity of drilling fluids control the hydraulics, hole cleaning and the mechanical friction between string ...
  • Drilling Optimisation on the Norwegian Continental Shelf: Opportunities in Well Design Practice 

    Harris, Patrick James (Master thesis, 2018-04-17)
    The purpose of this thesis was to attempt to provide evidence that Norway’s drilling fraternity is long overdue for a re-think in the way it drills wells. In so doing, the author has chosen to focus on slim well drilling ...
  • The cost of lice: Quantifying the impacts of parasitic sea lice on farmed salmon 

    Abolofia, Jay; Wilen, James E; Asche, Frank (Journal article; Peer reviewed, 2017-04)
    Diseases are an important challenge in aquaculture. However, most of what is known about the effect of diseases comes from laboratory experiments. Using a farm-level data set containing sea lice infestation counts for all ...
  • The Effect Of Titanium Nitride(TiN) Nanoparticle On The Properties & Performance Bentonite Drilling Fluid 

    Agonafir, Mesfin Belayneh; Berg, Vegard (Journal article; Peer reviewed, 2017)
    In recent years, the application of nano technology is attracting the oil and gas industry. Nanomaterials research results show an improving result of cement, drilling fluid and Enhanced Oil Recovery. In this paper, the ...
  • An accurate fatigue damage model for welded joints subjected to variable amplitude loading 

    Aeran, Ashish; Siriwardane, S.A. Sudath C.; Mikkelsen, Ove; Langen, Ivar (Journal article; Peer reviewed, 2017)
    Researchers in the past have proposed several fatigue damage models to overcome the shortcomings of the commonly used Miner's rule. However, requirements of material parameters or S-N curve modifications restricts their ...
  • Fatigue strength degradation of metals in corrosive environments 

    Adasooriya, Mudiyan Nirosha Damayanthi; Hemmingsen, Tor; Pavlou, Dimitrios (Journal article; Peer reviewed, 2017)
    Structures exposed to aggressive environmental conditions are often subjected to time-dependent loss of coating and loss of material due to corrosion; this causes reduction in the cross-sectional properties of the members, ...
  • Anomalous low-temperature thermodynamics of QCD in strong magnetic fields 

    Brauner, Tomas; Kadam, Saurabh (Journal article; Peer reviewed, 2017-11)
    The thermodynamics of quantum chromodynamics at low temperatures and in sufficiently strong magnetic fields is governed by neutral pions. We analyze the interacting system of neutral pions and photons at zero baryon chemical ...
  • Universal spacetimes in four dimensions 

    Hervik, Sigbjørn; Pravda, Vojtech; Pravdova, Alena (Journal article; Peer reviewed, 2017-10)
    Universal spacetimes are exact solutions to all higher-order theories of gravity. We study these spacetimes in four dimensions and provide necessary and sufficient conditions for universality for all Petrov types except ...
