A discussion on turbulent and undular bores using the models from the shallow water equations and the dispersive system.
(The University of Bergen, 2010-05-26)
The bore is a wave phenomenon that occurs in channels and rivers of shallow water. Referred to as a discharge wave, a bore is generated by a sudden increase of water flow. Bores appear in certain rivers as the tide pushes ...
Contemporary evolution caused by fisheries: Contributions from experimental studies
(The University of Bergen, 2012-11-06)
Evolutionary change is occurring within tens of generations or fewer in nature. This contemporary evolution is commonly caused by human activities, as they alter the selective pressures that the populations experience. ...
Spatial transcription of CYP1A in fish liver
(BioMed Central, 2007-12-05)
Background: The aim of this work was to study how evenly detoxifying genes are transcribed spatially in liver tissue of fish. Ten Atlantic salmon Salmo salar were intraperitoneally injected with 50 mg/kg of the strong ...
An expanded calibration model for inferring lakewater and air temperatures from fossil chironomid assemblages in northern Fennoscandia
Chironomid-temperature inference models based on an expanded data set of surface-sediment and limnological data from 53 Subarctic lakes in northern Fennoscandia have been developed using eight different numerical techniques, ...
Linear dependencies between non-uniform distributions in DES
(The University of Bergen, 2014-05-30)
Davies and Murphy explained some non-uniform distributions of the output from pairs and triplets of S-boxes in DES, and how they are completely dependent on some key bits. There are linear dependencies between these ...
Portfolio Optimization with PCC-GARCH-CVaR model
(The University of Bergen, 2014-06-02)
This thesis investigates the Conditional Value-at-Risk (CVaR) portfolio optimization approach combined with a univariate GARCH model and pair-copula constructions (PCC) to determine the optimal asset allocation for a ...
Possibility of Measuring the CP of a Higgs Boson at the LHC
(The University of Bergen, 2002)
Interpretation of geometrical effects in consequence modelling. Comparison study between the commercial consequence assessment tools FLACS and PHAST for flammable gas dispersion
(The University of Bergen, 2014-04-02)
Computational fluid dynamics and integral consequence modeling is today a crucial part of safety assessments worldwide. The models are widely used to predict the effects of ventilation patterns, hazardous gas dispersion, ...
Finite element modeling of ultrasound measurement systems for gas. Comparison with experiments in air.
(The University of Bergen, 2013-06-10)
A finite element based system model of an ultrasonic measurement system in air is developed. Simulations and experiments in air are compared.
