CO2 mobility reduction using foam stabilized by CO2- and water-soluble surfactants
(Journal article; Peer reviewed, 2021)Foam can reduce CO2 mobility to improve the sweep efficiency during injection into subsurface geological formations for CO2 storage and enhanced oil recovery. However, CO2 foams are thermodynamically unstable, so they must ... -

CO2-Foams for Enhanced Oil Recovery and CO2 Storage
(Doctoral thesis, 2019-03-01)Human prosperity, economic growth and energy supply have shown a strong positive correlation from the start of the industrial revolution until the present. During the 20th century, cheap and reliable energy from fossil ... -
CO2-injeksjon i Utsiraformasjonen - et studie av CO2/vann-kontakten og temperaturavhengige parametere
(Master thesis, 2012-06-01)Since the start-up in 1996 over 15 Mt CO2 have been injected in to the geological formation Utsira at the commercial CO2 storage project Sleipner. The propagation of CO2 in the reservoir has been monitored by time-lapse ... -
Coastal heathland vegetation is surprisingly resistant to experimental drought across successional stages and latitude
(Journal article; Peer reviewed, 2021)In the last decade, several major dwarf-shrub dieback events have occurred in northern European coastal heathlands. These dieback events occur after extended periods with sub-zero temperatures under snow-free conditions ... -
Coastal ocean fronts and eddies imaged with ERS 1 synthetic aperture radar
(Peer reviewed; Journal article, 1996-03-15)ERS 1 C band synthetic aperture radar (SAR) data were collected during the Norwegian Continental Shelf Experiment (NORCSEX) both in November 1991 during the ERS 1 commissioning phase and at different seasons in 1992 and ... -
Coastal permafrost was massively eroded during the Bølling-Allerød warm period
(Journal article; Peer reviewed, 2023)The Bølling-Allerød interstadial (14,700–12,900 years before present), during the last deglaciation, was characterized by rapid warming and sea level rise. Yet, the response of the Arctic terrestrial cryosphere during this ... -
Coastal submesoscale processes and their effect on phytoplankton distribution in the southeastern Bay of Biscay
(Journal article; Peer reviewed, 2021)Submesoscale processes have a determinant role in the dynamics of oceans by transporting momentum, heat, mass, and particles. Furthermore, they can define niches where different phytoplankton species flourish and accumulate ... -
COASTWATCH´95: ERS 1/2 SAR detection of natural film on the ocean surface
(Peer reviewed; Journal article, 1998-10-15)Ocean mesoscale phenomena such as eddies and current convergence zones can often be seen in synthetic aperture radar (SAR) images due to characteristic patterns caused by natural film induced damping of the waves. Such ... -
Cod spawning in the Borgundfjord Marine Protected Area
(Master thesis, 2020-06-27)The Norwegian coastal cod population north of 62°N declined in the years from 1997 to 2005 and has since remained low. The Borgundfjord has since 2009 served as an extractive Marine Protected Area (MPA) for protecting the ... -
Code-based cryptography: A superficial introduction
(Master thesis, 2018-10-06)This thesis provides an overview of some known post-quantum cryptography schemes with special attention given to code-based schemes. It also discusses some challenges that may arise trying to implement a McEliece-like ... -
Coded communication on the Internet
(Master thesis, 2019-06-26)The Internet is giving people many opportunities to interact, but for latency-sensitive activities, there is still room for improvement. It is not always good enough that messages arrive; some times they should arrive ... -
Coding for DNA-based Storage Systems
(Doctoral thesis, 2024-05-24)DNA-basert lagring, eller lagring av brukerdata i deoksyribonukleinsyre (DNA) tråder, kan teoretisk gi dramatisk høyere lagringskapasitet og lagringsrobusthet sammenlignet med dagens lagringsteknologier. Flere småskalaek ... -
Coding for passive RFID communication
(Doctoral thesis, 2012-08-31)This dissertation elaborates on channel coding for reliable communication in passive RFID systems. RFID applications have been developed and used widely. Since a passive RFID tag has no power requirements, passive RFID has ... -
Coding for Privacy in Distributed Computing
(Doctoral thesis, 2023-04-21)I et distribuert datanettverk samarbeider flere enheter for å løse et problem. Slik kan vi oppnå mer enn summen av delene: samarbeid gjør at problemet kan løses mer effektivt, og samtidig blir det mulig å løse problemer ... -
Codium fragile in Norway: subspecies identity and morphology
(Peer reviewed; Journal article, 2016)The green alga Codium fragile consists of 10 subspecies, of which subspecies fragile is a well-known invasive seaweed. Morphological work carried out in the 1950s suggested that there were three subspecies along the Norwegian ... -
Codium fragile subsp. fragile and Sargassum muticum: Non-native seaweeds in a changing environment
(Doctoral thesis, 2017-11-17)Non-native species have received increasing scientific and public attention over the last three decades, and have been identified as a threat to biodiversity. However, coastal environments may also be affected by several ... -
Coevolution between king crabs (Paguridae: Lithodinae) and parasitic barnacles (Cirripedia: Rhizocephala)
(Doctoral thesis, 2017-01-27)Molecular evidence has established that king crabs (Lithodinae) are gigantic hermit crabs without a gastropod shell to protect their abdomen. Secondarily, the abdomen has become calcified and flexed, in a crab-like manner. ... -

Coherence for Monoidal and Symmetric Monoidal Groupoids in Homotopy Type Theory
(Doctoral thesis, 2021-12-03)Homotopy Type Theory (HoTT) is a variant of Martin-Löf Type Theory (MLTT) developed in such a way that types can be interpreted as infinity-groupoids, where the iterated construction of identity types represents the different ...
