Permittivity measurements using dual open ended coaxial probes
(The University of Bergen, 2012-11-19)
The motivation for this study has been to conduct a feasibility study on a measuring device to monitor hydrate formation close to the inner surface of a pipe where a multiphase hydrocarbon fluid mixture is flowing. This ...
Correlations among elliptic flow parameter, impact parameter, and multiplicity
The elliptic flow parameter, v2, in the Fourier expansion of the event-by-event charged-particle multiplicity azimuthal distribution in the momentum space is studied by taking into account the multiplicity fluctuations. ...
Reaching towards higher masses of supersymmetric particles decaying to tau leptons
(The University of Bergen, 2014-06-30)
This thesis presents an optimisation of the search for SUSY in final states with one tau lepton, jets and missing transverse energy. The SUSY model considered is mSUGRA with the parameter values: A_0 = -2m0, tan(beta) ...
Measurement of electrons from beauty hadron decays in pp collisions at root √s=7 TeV
The production cross section of electrons from semileptonic decays of beauty hadrons was measured at mid-rapidity (|y| < 0.8) in the transverse momentum range 1 < pT <8 GeV/c with the ALICE experiment at the CERN LHC in ...
Characterization of Hyper Spectral Irradiance and Radiance Sensors
(The University of Bergen, 2013-09-11)
It is surprisingly problematic to to accurately measure light in the laboratory. Even more so when measuring in the field. There are lots of areas where measuring light spectrum and irradiance outside a laboratory is ...
Acoustic measurement of liquid density with applications for mass measurement of oil
(The University of Bergen, 2007-11-23)
Vannbasert eor i oppsprukne bergarter - økt oljeutvinning ved kjemikalietilsetning i injeksjonsvannet
(The University of Bergen, 2010-06-01)
En stor del av verdens hydrokarbonreserver finnes i karbonater. Karbonatreservoarer er komplekse fordi reservoarbergarten ofte er sprø og sprekker lett. Mineralsammensetningen av karbonater gjør poreoverflaten mer tilbøyelig ...
Simulation of viscous instabilities in miscible and immiscible displacement
(The University of Bergen, 2008-06-09)
This study includes modeling of viscous instabilities at both miscible and immiscible displacement. Oil recovery of heavy oil leads to unstable displacement for adverse mobility ratio for both miscible and immiscible ...
Måling av forholdet mellom ladning og masse for elektronet - Utførelse og laboratorieveiledning
(The University of Bergen, 2010-05-31)
Hensikten med denne masteroppgaven er å lage en laboratorieveiledning til en øvelse i et fag for laveregradstudenter ved Universitetet i Bergen. Foruten å finne en interessant fysisk verdi er hovedhensikten at studentene ...
Measurements of four-lepton production at the Z resonance in pp collisions at √s = 7 and 8 TeV with ATLAS
(American Physical Society, 2014-06-13)
Measurements of four-lepton (4ℓ, ℓ=e,μ) production cross sections at the Z resonance in pp collisions at the LHC with the ATLAS detector are presented. For dilepton and four-lepton invariant mass regions mℓ+ℓ−>5 GeV and ...
