Experimental and theoretical study on the effect of wall roughness on the phenomenon end of the vortex in swirl tubes
(The University of Bergen, 2011-11-18)
In this thesis, a combination of experimental measurements and numerical simulations are used to investigate the phenomenon "End of the Vortex" in swirl tubes. The main focus here has been comparing swirl tubes containing ...
Two Higgs Doublets plus One Dark Matter Singlet
(The University of Bergen, 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 ...

Invariant Mass Distributions of SUSY Cascade Decays
(The University of Bergen, 2011-06-01)
If supersymmetry (SUSY) is realised at experimental energies and R-parity is conserved, sparticles might be produced and decay in cascades at the LHC. A neutral LSP will escape detection, complicating the reconstruction ...
Low-energy surface vibration measurements on the alpha-quartz (0001) surface
(The University of Bergen, 2011)
Despite the enormous range of usages, only little is known about the dynamic and structural properties of quartz (SiO2) surfaces on the atomic scale. The main reason for this is probably that quartz is an insulator, with ...
Space and Energy Distribution of Dark Matter
(The University of Bergen, 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. ...
CP Violation in the Two Higgs Doublet Model
(The University of Bergen, 2010-06)
We look into CP violating properties in the two Higgs Doublet Model and search for the possibility that Spontaneous and Explicit CP Violation have no physical difference.
Experimental investigation of particle trajectory through an hydrocyclone using a Positron Emission Tomography (PET) scanner
(The University of Bergen, 2010-08-31)
Hydrocyclones are much used in process technology and in many different industrial applications. In the oil and gas industry the hydrocyclones, both gas-solid and liquidsolid cyclones are widely used. Getting the sand ...
Long-range interactions and dynamics of excited atoms
(The University of Bergen, 2010-06-10)
A study of the dynamics of excited hydrogenic atoms, with emphasis on analytical and numerical calculations of the time-independent and the time-dependent Schrõdinger equation. A short description of Rydberg atoms and their ...
Studier av algoritmer for tau-identifikasjon
(The University of Bergen, 2010-05-31)
Mange signaturer for ny fysikk i ATLAS vil henfalle til eit eller fleire tau-lepton. Derfor har ATLAS utvikla verktøy for identifikasjon av tau-lepton som henfall eit eller fleire pion. Verktøya er kompliserte og inneheld ...
