Sequential Data Assimilation in High Dimensional Nonlinear Systems
(The University of Bergen, 2011-10-21)
Since its introduction in 1994, the ensemble Kalman filter (EnKF) has gained a lot of attention as a tool for sequential data assimilation in many scientific areas. Due to its computationally fast and easy to implement ...
3D stochastic modelling of fault zones in siliciclastic reservoirs. Implications for reservoir description and fluid flow modelling
(The University of Bergen, 2014-12-16)
Fault zones in siliciclastic rocks form distinct volumetric entities and typically exhibit great structural complexity. While it has been considered that the main impact of fault zones to fluid flow is to baffle or block ...
The distribution of Skagerrak coastal cod (Gadus morhua) in relation to oxygen depletion, temperature and salinity, studied by acoustic telemetry in the Tvedestrand fjord in south-eastern Norway
(The University of Bergen, 2013-06-02)
Decreased oxygen levels in coastal waters due to human activities are receiving increased attention as a potential threat to marine biodiversity and harvestable resources. Hydrographic measurements and hydroacoustic single ...
Process Monitoring of Continuous Flow Organic Syntheses by means of Inline Fiber Optical Raman Spectroscopy
(The University of Bergen, 2010-02-08)
The objective of the current study was to investigate the feasibility of the inline optical fiber Raman spectroscopy as a tool for the process monitoring of the continuous flow organic syntheses. The synthesis of ...
Characterization of Linked Polymer Solutions (LPS) – Influence of salinity and divalent ions
(The University of Bergen, 2011-05-31)
Water flooding with addition of polymers cross-linked by polyvalent ions (LPS) has proven to increase the oil recovery both in field applications and laboratory studies, but with constraints on the brine salinity. With of ...
Vertical mixing in the marginal ice zone of the Barents Sea Spatial and temporal variation of oceanic turbulence - observations and numerical model experiments
(The University of Bergen, 2007-01-12)
Vertical mixing affects water mass modification, biological productivity, and chemical fluxes in the ocean, but its response to forcing and variability in time and space in seasonally ice-covered seas is inadequately known. ...
High order volume preserving integrators for three kinds of divergence-free vector fields via commutators
(Huiyan Xue, 2013)
In this paper, we focus on construction of high order volume preserving integrators for divergence-free vector fields of the monomial basis, exponential basis and tensor product of the monomial and exponential basis. We ...
Læring av matematikk gjennom prosjekter i teknologi og design
(Caspar forlag og kursvirksomhet, 2006)
Separating blue whiting (Micromesistius poutassou Risso, 1826) from myctophid targets using multi-frequency methods
(The University of Bergen, 2008)
Blue whiting (Micromesistius poutassou Risso, 1826) is a physoclists species, widely distributed in the Barents Sea, Norwegian Sea and Mediterranean Sea. They appear on the continental slope and shelf, in high concentration ...
Early post-deglaciation shorelines and sea-level changes along Hardangerfjorden and adjacent fjord areas, W. Norway
(The University of Bergen, 2008-09-05)
