(The University of Bergen, 2006-05-16)
Classification of protein structures
(The University of Bergen, 1999-12)
Empirical and Numerical Evaluation of Mechanisms in Gas Production from CH4-Hydrates: Emphasis on Kinetics, Electrical Resistivity, Depressurization and CO2-CH4 Exchange
(The University of Bergen, 2013-12-13)
Focus is shifted towards renewable energy and sources of natural gas as the demand for cleaner energy continues to increase with global awareness on anthropogenic climate change. Methane (CH4) provides advantages such as ...
Optimization of Separation Efficiency in Temperature Programmed Gas Chromatography : Application of Response Surface Methodology
(The University of Bergen, 2014-03-14)
Chromatographic efficiency can be defined as the maximal number of chromatographic peaks that can be separated within a section of a chromatogram. In isothermal gas chromatography (GC) it is usually measured by number of ...
Data Profiling to Reveal Meaningful Structures for Standardization
(The University of Bergen, 2009-11-20)
Today many organisations and enterprises are using data from several sources either for strategic decision making or other business goals such as data integration. Data quality problems are always a hindrance to effective ...
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 ...
Nanostructuring of free-standing, dielectric membranes using electron-beam lithography
(American Institute of Physics, 2013)
Nanostructured dielectric membranes are used in several applications ranging from de Broglie matter-wave optical elements to photonic crystals. Precise pattern transfer and high aspect ratio structures are crucial for ...
Sammenligning av spredningsmodellering med kodene PHAST og FLACS, for “tyngre en luft” gassjeter med horisontalt sammenstøt, og valideringssimuleringer av MUST forsøkene.
(The University of Bergen, 2011-01-20)
Denne rapporten er et arbeid som sammenligner to dataverktøy, PHAST og FLACS vedrørende ulike spredningsscenarier for fluider, først og fremst tung-gassutslipp. Det er utført en rekke simuleringer som ligger til grunn for ...

Environmental Remediation: Removal of polycyclic aromatic hydrocarbons Dissertation
(The University of Bergen, 2012-08-17)
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous persistent semi-volatile organic compounds. They are contaminants that are resistant to degradation and can remain in the environment for long periods due to their ...
