Exploring spatio-temporal patterns of palynological changes in Asia during the Holocene
(Journal article; Peer reviewed, 2023-05-05)Historical legacies influence present-day ecosystem composition and dynamics. It is therefore important to understand the long-term dynamics of ecosystems and their properties. Analysis of ecosystem properties during the ... -
Exploring Subexponential Parameterized Complexity of Completion Problems
(Peer reviewed; Journal article, 2014-02-19)Let F be a family of graphs. In the F-Completion problem, we are given an n-vertex graph G and an integer k as input, and asked whether at most k edges can be added to G so that the resulting graph does not contain a graph ... -
Exploring the central and peripheral systems controlling appetite, food intake and digestion in Atlantic halibut (Hippoglossus hippoglossus) larvae- Tissue distribution, ontogeny and effects of food attractants
(Master thesis, 2019-06-25)Atlantic halibut (Hippoglossus hippoglossus) is a cold-water belonging to the Pleuronectidae family and is native to Norwegian waters. Halibut is a high valued food species that have been overfished and wild-stock collapses, ... -
Exploring the Condition of Fish Welfare and Microbial Dynamics in Egget® – a Novel Closed Aquaculture System at Sea
(Master thesis, 2023-10-02)The Norwegian Atlantic salmon (Salmo salar) aquaculture industry faces significant challenges, prompting the need for innovative approaches to enhance sustainability. One such innovation is the prototype Egget®, a novel ... -
Exploring the coupled ocean and atmosphere system with a data science approach applied to observations from the Antarctic Circumnavigation Expedition
(Journal article; Peer reviewed, 2021)The Southern Ocean is a critical component of Earth's climate system, but its remoteness makes it challenging to develop a holistic understanding of its processes from the small scale to the large scale. As a result, our ... -
Exploring the CP-violating Inert-Doublet Model
(Peer reviewed; Journal article, 2011-06-01)We have explored properties of an extension of the Inert Doublet Model by the addition of an extra non-inert scalar doublet. The model offers a possibility of CP violation in the scalar sector and a candidate for the Dark ... -
Exploring the evolution of protein function in Archaea
(Peer reviewed; Journal article, 2012-05-30)Background: Despite recent progress in studies of the evolution of protein function, the questions what were the first functional protein domains and what were their basic building blocks remain unresolved. Previously, we ... -
Exploring the Fermentation Parameters of Kombucha on Caffeine and pH Using Experimental Design and the Feasibility of Raman Spectroscopy in Kombucha Analysis
(Master thesis, 2023-09-30)Kombucha shows promising growth potential due to its claimed health benefits. Through an experimental design, the impact of the fermentation parameters on color and appearance, pH and caffeine content was further understood ... -
Exploring the Microseismicity of the Gakkel Ridge from Arctic Sea Ice
(Master thesis, 2013-06-03)Monitoring of microseismicity is an important tool to understand the magmatism, tectonics and hydrothermal circulation of a mid-oceanic ridge. In the presence of sea ice, use of ocean bottom seismometers is not practical, ... -
Exploring the Phase Space of Jet Splittings at ALICE using Grooming and Recursive Techniques
(Peer reviewed; Journal article, 2019)Hard splittings in the evolution of a hard scattered parton may be modified by the presence of a dense strongly interacting medium. Grooming procedures can be used to isolate such hard components of a jet and allows one ... -
Exploring the potential of citizen science for de novo sequencing of MS/MS spectra
(Master thesis, 2022-06-15)Proteomics is the large-scale study of the function and structure of proteins expressed in a given sample. It generally uses mass spectrometry-based technologies to detect and identify changes in the proteome. One of the ... -
Exploring the potential of the RPA system SUMO for multipurpose boundary-layer missions during the BLLAST campaign
(Peer reviewed; Journal article, 2016-06-24)In June and July 2011 the RPAS (Remotely Piloted Aircraft System) SUMO (Small Unmanned Meteorological Observer) performed a total number of 299 scientific flights during the BLLAST (Boundary Layer Late Afternoon and Sunset ... -
Exploring the use of nanofluids in pump-free systems for solar thermal applications
(Journal article; Peer reviewed, 2023)By using nanofluids as a working fluid in pump-free designs, thermal energy systems can become more efficient and have reduced maintenance costs, ultimately extending the system’s lifespan. In this paper, our goal is to ... -
Exploring virtualisation tools with a new virtualisation provisioning method to test dynamic grid environments for ALICE grid jobs over ARC grid middleware
(Peer reviewed; Journal article, 2014)The Nordic Tier-1 centre for LHC is distributed over several computing centres. It uses ARC as the internal computing grid middleware. ALICE uses its own grid middleware AliEn to distribute jobs and the necessary software ... -
Exploring Ways of Creating an AI Drawing Assistant
(Master thesis, 2022-07-01)Making a digital drawing assistant is a complicated problem for the simple reason that we are trying to make a computer program understand and create something that are as abstract as a drawing. Thus, there have been many ... -
Exponential time algorithms: Structures, measures, and bounds
(Doctoral thesis, 2008-12-05)This thesis studies exponential time algorithms, more precisely, algorithms exactly solving problems for which no polynomial time algorithm is known and likely to exist. Interested in worst–case upper bounds on the running ... -
Export of calcium carbonate corrosive waters from the East Siberian Sea
(Peer reviewed; Journal article, 2017-04-05)The Siberian shelf seas are areas of extensive biogeochemical transformation of organic matter, both of marine and terrestrial origin. This in combination with brine production from sea ice formation results in a cold ... -
Export of ice sheet meltwater from Upernavik fjord, West Greenland
(Journal article; Peer reviewed, 2022)Meltwater from Greenland is an important freshwater source for the North Atlantic Ocean, released into the ocean at the head of fjords in the form of runoff, submarine melt, and icebergs. The meltwater release gives rise ...
