Multifrequency acoustic target strength of Northern krill
(The University of Bergen, 2009-03-30)
Although this thesis is a dissertation based on articles, an exhaustive overview on the main issues involved is also presented *. This is due to the necessity to summarize the numerous aspects of the problem, as well as ...
Methane Production from Natural Gas Hydrates. Impact of Temperature on CH4 -CO2 Exchange rate in Hydrate Bearing Sandstone
(The University of Bergen, 2013-06-17)
Dissociation by pressure depletion, thermal stimulation and/or injection of inhibitors are three known methods for gas production from natural gas hydrates. Challenges concerning these production methods are water and sand ...
Search for neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at √s= TeV with the ATLAS detector
A search for the neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is performed on data from proton-proton collisions at a centre-of-mass energy of 8TeV collected ...
A setup for electrical tests of ATLAS SCT barrel modules
(The University of Bergen, 2003)
The ATLAS SemiConductor Tracker (SCT) is part of the inner detector in the ATLAS detector at the LHC complex at CERN. SCT will consist of a system of silicon strip detectors with digital readout, reading out space point ...
Decontamination of persistent organic pollutants in fishmeal and fish oil. Process optimization and modeling
(The University of Bergen, 2011-10-07)
Persistent organic pollutants (POPs) are fat soluble chemical substances that persist in the environment and bioaccumulate in the food chain. Through long-range environmental transportation by air, water and migratory ...
Investigation of the possibilities for seabottom characterization using echosounder data
(The University of Bergen, 2009-11-18)
This thesis focuses mainly on using the information present in the first echo returned from the seafloor, using a normal-incidence echosounder, to characterize or classify the seabed. This is done using a monostatic setup ...
Two-photon double ionization of helium by attosecond laser pulses: Evidence of highly correlated electron motion
(American Physical Society, 2012)
We apply a recently developed ab initio numerical framework to investigate the angular distributions of the emitted electrons in the immediate proximity of the threshold for the two-photon double ionization of helium. Provided ...
Måling av akustisk spreiing fra makrellbein
(The University of Bergen, 2006-06)
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 ...
