• Critical Measures and Parameter Space of Jenkins-Strebel Quadratic Differentials ﻿

(The University of Bergen, 2012-05-07)
The thesis is devoted to applications of the theory of quadratic differentials to the problems of construction of critical measures, that provide critical values of the logarithmic energy of a charge system on the ...

Master thesis
• Critical vulnerabilities of marine and sea ice–based ecosystems in the high Arctic ﻿

(Springer, 2010-12-01)
The objectives of this paper are to summarise: (1) observed 20th-century and projected 21st-century changes in key components of the Arctic climate system and (2) probable impacts on the Arctic marine environment, with ...

• Crude oil components with affinity for gas hydrates in petroleum production ﻿

(The University of Bergen, 2007-06-28)
Some crude oils are believed to contain natural inhibiting components that can prevent hydrate plugging of oil pipelines in petroleum production. A method for classification of the oils that form hydrate plugs, as opposed ...
Doctoral thesis
• Crude oil exposures reveal roles for intracellular calcium cycling in haddock craniofacial and cardiac development ﻿

(Nature Publishing Group, 2016-08-10)
Recent studies have shown that crude oil exposure affects cardiac development in fish by disrupting excitation-contraction (EC) coupling. We previously found that eggs of Atlantic haddock (Melanogrammus aeglefinus) bind ...

• Crustal structure of the ultra-slow spreading Knipovich Ridge, North Atlantic, along a presumed ridge segment center ﻿

(Springer, 2010)
A combined ocean bottom seismometer, multichannel seismic reflection and gravity study has been carried out along the spreading direction of the Knipovich Ridge over a topographic high that defines a segment center. ...
Peer reviewedJournal article
• Crustal transect from the Knipovich Ridge to Bear Island across the western Barents Sea margin ﻿

(The University of Bergen, 2010-06-08)
A crustal model of a 322 km long transect from the Knipovich Ridge to Bear Island (Bjørnøya) has been obtained by use of reflection seismic data and wide angle Ocean Bottom Seismometer (OBS) data. Further constraints of ...
Master thesis
• Crustal velocity-depth model from Barents Sea Southeast based on a SSW-NNE oriented OBS-profile transecting the Tiddlybanken Basin and the Bjarmeland Platform ﻿

(The University of Bergen, 2014-11-20)
A crustal model transecting the Tiddlybanken Basin, Hjalmar Johansen High and Bjarmeland Platform in the Barents Sea Southeast have been constructed with emphasis on P-wave phase picking and subsequent P-wave model-building ...
Master thesis
• The crypsis hypothesis explained: a reply to Jayasuriya et al. (2015) ﻿

(Cambridge University Press, 2015-08-18)
In imbibing seeds, resumption of metabolism leads to the unavoidable release of volatile by-products that are perceived as cues by rodent seed predators. The crypsis hypothesis proposes that the primary function of a ...

• Cryptanalysis of Cryptographic Primitives and Related Topics ﻿

(The University of Bergen, 2011-09-09)
This thesis has focused on the cryptanalysis of cryptographic primitives especially stream ciphers which is an important topic in cryptography. Additionally, the security of network coding is discussed and improved with ...
Doctoral thesis
• Cultivation and genomics of extremophiles from a deep and hot North Sea oil reservoir ﻿

(The University of Bergen, 2014-10-02)
In this study, production water from the Troll B oilfield in the North Sea has been used as a source in order to isolate and characterize new extremophilic prokaryotes. Anaerobic enrichment cultures with different carbon ...
Master thesis
• Current systematic carbon-cycle observations and the need for implementing a policy-relevant carbon observing system ﻿

(Copernicus Publications, 2014-07-03)
A globally integrated carbon observation and analysis system is needed to improve the fundamental understanding of the global carbon cycle, to improve our ability to project future changes, and to verify the effectiveness ...
Journal article
• Current systems associated with Non-Conjugate Aurora ﻿

(The University of Bergen, 2015-01-20)
The main goal of this Thesis is twofold. First, we want to develop a solid method for identifying the field aligned currents related to the specific non-conjugate auroral features identified by Reistad et al. [2013] and ...

• Current Trends for 4D Space-Time Topology for Semantic Flow Segmentation ﻿

(Elsevier, 2011)
Journal article
• Curve Density Estimates ﻿

(Blackwell Publishing Ltd., 2011-06-28)
In this work, we present a technique based on kernel density estimation for rendering smooth curves. With this approach, we produce uncluttered and expressive pictures, revealing frequency information about one, or, ...

• Curve-Centric Volume Reformation for Comparative Visualization ﻿

(IEEE, 2009-10-11)
We present two visualization techniques for curve-centric volume reformation with the aim to create compelling comparative visualizations. A curve-centric volume reformation deforms a volume, with regards to a curve in ...

• Cutoff latitude variation during solar proton events: Causes and consequences ﻿

(WileyAmerican Geophysical Union, 2015-01)
To accurately quantify the effect of solar proton events (SPEs) on the atmosphere requires a good estimate of the particle energy deposition in the middle atmosphere (60–100 km) and how the energy is distributed globally. ...

• Cyclopentane Hydrate for Hydrate Wetting Studies ﻿

(The University of Bergen, 2013-06-03)
Abstract Gas hydrates are often found in the systems for production of petroleum, natural gas and water systems, which is highly undesirable. In some systems the hydrates can form rapidly into large plugs and agglomerate ...
Master thesis
• Cytoskeleton-mediated templating of complex cellulose-scaffolded extracellular structure and its association with oikosins in the urochordate Oikopleura ﻿

(Springer, 2010)
Oriented cellulose deposition is critical to plant patterning and models suggest microtubules constrain cellulose synthase movements through the plasma membrane. Though widespread in plants, urochordates are the only animals ...

• D meson elliptic flow in non-central Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76TeV ﻿

(American Physical Society, 2013-09)
Azimuthally anisotropic distributions of $D^0, D^+$ and $D^{*+}$ mesons were studied in the central rapidity region (|y| < 0.8) in Pb-Pb collisions at a centre-of-mass energy $\sqrt{s_{NN}}$ = 2.76 TeV per nucleon-nucleon ...
