Geogebra og funksjonar. Elevane si tilnærming til representasjonsskifte i arbeid med funksjonar, med og utan bruk av Geogebra, i matematikk på vidaregåande skule.
(Master thesis, 2018-06-20)Digitale hjelpemiddel har for lengst fått sin plass i matematikkundervisninga i norsk skule. I den vidaregåande skulen har dataprogram med grafteiknar også langt på veg erstatta kalkulatorar, som digitalt hjelpemiddel i ... -
Geographic distribution, abundance, diet, and body size of invasive pink salmon (Oncorhynchus gorbuscha) in the Norwegian and Barents Seas, and in Norwegian rivers
(Journal article; Peer reviewed, 2022)We report for the first time the geographic distribution, abundance, diet, and body size of invasive pink salmon (Oncorhynchus gorbuscha) in the Norwegian and Barents Seas and Norwegian coast and rivers. We found that pink ... -
Geographic variation in gene flow from a genetically distinct migratory ecotype drives population genetic structure of coastal Atlantic cod (Gadus morhua L.)
(Journal article; Peer reviewed, 2022)Identifying how physical and biotic factors shape genetic connectivity among populations in time and space is essential to our understanding of the evolutionary trajectory as well as the management of marine species. ... -
Geographical and management related factors affecting lambs of outwintered sheep along the west coast of Norway. A baseline study in the research project feral sheep in coastal heats - developing a sustainable local industry in vulnerable cultural landscapes
(Master thesis, 2008)The Ancient Norse breed of outwintered sheep (ANBOS/Feral sheep) are the traditional sheep of Norwegian coastal heathlands, an open semi-natural landscape now threatened by regrowth due to cessation of management. One of ... -
Geologic controls on fluid flow and seismic imaging of faults in carbonate rocks : Insights from quantitative outcrop analysis and reflection seismic modeling
(Doctoral thesis, 2023-06-16)Utforsking av undergrunnen har historisk sett hovudsakleg vore drive av økonomiske insentiv gjennom leiting etter hydrokarbon og andre geologiske ressursar. I nyare tid, derimot, har geologiens rolle i det grøne skiftet ... -
Geological constraints on hydrocarbon contacts in the greater Norne area
(Master thesis, 2018-06-13)The understanding of the geological constraints on the position of fluid contacts is important for the evaluation of the remaining resources on the Norwegian Continental Shelf. Different mechanisms can lead to filled, ... -
Geological contraints on the position of hydrocarbon-contacts in the Gina Krog and Sleipner East areas
(Master thesis, 2018-08-22)Knowledge of the geological constrains on the position of hydrocarbon-water contacts are crucial in terms of hydrocarbon exploration. The controlling mechanisms have a large impact on the in-place volumes in a potential ... -
Geological control on dinosaurs’ rise to dominance: Late Triassic ecosystem stress by relative sea level change
(Journal article; Peer reviewed, 2020)The Late Triassic is enigmatic in terms of how terrestrial life evolved: it was the time when new groups arose, such as dinosaurs, lizards, crocodiles and mammals. Also, it witnessed a prolonged period of extinctions, ... -
Geological controls on fluid flow and seepage in western Svalbard fjords, Norway. An integrated marine acoustic study
(Doctoral thesis, 2015-11-06)The study of seabed fluid flow facilitates assessment of gas hydrate accumulation, submarine geohazards, localizing shallow and deep hydrocarbon reservoirs. Other fluid flow related studies include for example the benthic ... -
Geological evolution and stratigraphic relationships of the ophiolitic terrane in the outer Hardangerfjord area: evidence from geochronology and geochemistry
(Master thesis, 2017-10-13)Field relations, geochemistry and U-Pb single zircon ages have provided new information about the rocks of the outer Hardangerfjord area that represent a part of the Upper Ordovician ophiolitic terrane of south-western ... -
Geological Storage of CO2: Sensitivity and Risk Analysis
(Doctoral thesis, 2014-04-10)Geological CO2 storage has the potential to be a key technology for prevention of industrial CO2 emission into the atmosphere. A successful storage operation requires safe geological structures with large storage capacity. ... -
Geomagnetic Response to Rapid Increases in Solar Wind Dynamic Pressure: Event Detection and Large Scale Response
(Journal article; Peer reviewed, 2022)Discontinuities in the solar wind trigger a variety of processes in the magnetosphere-ionosphere system. A rapid increase in solar wind dynamic pressure causes compression of the magnetosphere. This manifests itself as a ... -
Geometric and Spectral Properties of Hypoelliptic Operators
(Master thesis, 2017-07-26) -
Geometric controls of tidewater glacier dynamics
(Journal article; Peer reviewed, 2022)Retreat of marine outlet glaciers often initiates depletion of inland ice through dynamic adjustments of the upstream glacier. The local topography of a fjord may promote or inhibit such retreat, and therefore fjord geometry ... -
Geometric Frustration on the Trillium Lattice in a Magnetic Metal-Organic Framework
(Journal article; Peer reviewed, 2022)In the dense metal-organic framework Na[Mn(HCOO)3], Mn2+ ions (S=52) occupy the nodes of a “trillium” net. We show that the system is strongly magnetically frustrated: the Néel transition is suppressed well below the ... -
Geometric Planar Networks on Bichromatic Points
(Journal article; Peer reviewed, 2020)We study four classical graph problems – Hamiltonian path, Traveling salesman, Minimum spanning tree, and Minimum perfect matching on geometric graphs induced by bichromatic ( Open image in new window and Open image in new ... -
Geometric reconstruction and persistence methods
(Master thesis, 2020-07-01)In the present work we reconstruct the homotopy type of an unknown Euclidean subspace from a known sample of data. We carry out such reconstruction through generalized Čech complexes, by choosing radii which are less or ... -
Geometric rough paths on infinite dimensional spaces
(Journal article; Peer reviewed, 2022)Similar to ordinary differential equations, rough paths and rough differential equations can be formulated in a Banach space setting. For α ∈ (1/3,1/2), we give criteria for when we can approximate Banach space-valued ... -
