Estimation of discards in the commercial trawl fishery for Northeast Arctic cod (Gadus morhua L.) and some effects on assessment
(Master thesis, 2001)Discarding of small fish has been and still is a large problem in many fisheries. It is a problem because most of the discarded fish die and are a direct loss to the biomass of the stock. When discards occur and it is not ... -
Estimation of elastic moduli of mixed porous clay composites
(Peer reviewed; Journal article, 2011-01-13)We have developed a procedure for estimating the effective elastic properties of various mixtures of smectite and kaolinite over a range of confining pressures, based on the individual effective elastic properties of pure ... -
Estimation of groundwater storage loss for the Indian Ganga Basin using multiple lines of evidence
(Journal article; Peer reviewed, 2023)We used remote sensing data, field observations and numerical groundwater modelling to investigate long-term groundwater storage losses in the regional aquifer of the Ganga Basin in India. This comprised trend analysis for ... -
Estimation of In-situ Polymer Rheology by Simulation of Radial Flow Experiment
(Master thesis, 2017-06-22)Most experiments about in-situ rheology of polymer flow in porous media presented in literature is executed on linear cores and hence, performed during steady state conditions where the pressure drop is constant over the ... -
Estimation of Ocean Biogeochemical Parameters in an Earth System Model Using the Dual One Step Ahead Smoother: A Twin Experiment
(Journal article; Peer reviewed, 2022)Ocean biogeochemical (BGC) models utilise a large number of poorly-constrained global parameters to mimic unresolved processes and reproduce the observed complex spatio-temporal patterns. Large model errors stem primarily ... -
Estimation of Relative Permittivity and Thickness for Dielectric Materials Using an Open-Ended Waveguide Sensor
(Master thesis, 2016-09-10)The main goal of this thesis has been to conduct a feasibility study on an open-ended waveguide sensor as a tool for estimating the relative permittivity and thickness of dielectric layers in the thickness range 0.5-5 cm. ... -

Estimering av permeabilitet med bruk av adaptiv parameterisering
(Master thesis, 2009-07-17) -
Et dynamisk studium av stormen Narve - et kaldluftsutbrudd i Finnmark - ved hjelp av observasjoner og numeriske simuleringer
(Master thesis, 2007)Title: "A dynamical study of the storm Narve - a cold air outbreak in Finnmark - with the use of observations and numerical simulations."During the storm Narve in January 2006 strong winds from land were blowing during six ... -
Et Killing the Winner-studie av visuelle og taktile organismer i Svartehavet
(Master thesis, 2016-06-01)I løpet av de to siste tiårene har det blitt rapportert om trender som tyder på at det er en økning i manetblomstringer i flere store marine økosystemer. Parallelt med den økende oppblomstringen av maneter er det også ... -
Et kritisk og konstruktivt blikk på naturfaget i norsk skole
(Chapter, 2021)Dette kapitlet retter et kritisk, men konstruktivt blikk på naturfag, og foretar en gjennomgang av naturfag og naturfagdidaktikk innen forskning og i praksis. Kapitlet starter med å beskrive og diskutere naturfagets ... -
Et longitudinelt studium av utvalgte gjellepatogener assosiert med gjellesykdom hos oppdrettslaks i Vest-Norge.
(Master thesis, 2015-01-08)Studien var en longitudinel undersøkelse av forekomst av gjellepatogener. En populasjon av høstutsatt Atlantisk laks på Vestlandet ble fulgt gjennom ett år i sjø (oktober 2013 - september 2014). Det ble utført månedlige ... -
Etablering av holocen askestratigrafi i innsjøarkiver for Vest-Norge
(Master thesis, 2020-07-04)Askestratigrafi er et mye brukt verktøy til kronostratigrafisk korrelering og datering. For vest-norske innsjøer er det tefrakronologiske rammeverket svært begrenset, og en etablering av en askestratigrafi derfra kan gi ... -
ETH Tight Algorithms for Geometric Intersection Graphs: Now in Polynomial Space
(Journal article; Peer reviewed, 2021)De Berg et al. in [SICOMP 2020] gave an algorithmic framework for subexponential algorithms on geometric graphs with tight (up to ETH) running times. This framework is based on dynamic programming on graphs of weighted ... -
ETH-Tight Algorithms for Finding Surfaces in Simplicial Complexes of Bounded Treewidth
(Journal article; Peer reviewed, 2022)Given a simplicial complex with n simplices, we consider the Connected Subsurface Recognition (c-SR) problem of finding a subcomplex that is homeomorphic to a given connected surface with a fixed boundary. We also study ... -
ETH-tight algorithms for long path and cycle on unit disk graphs
(Journal article; Peer reviewed, 2020)We present an algorithm for the extensively studied Long Path and Long Cycle problems on unit disk graphs that runs in time 2O(√k)(n + m). Under the Exponential Time Hypothesis, Long Path and Long Cycle on unit disk graphs ... -
Ethernet-Based Control System and Data Readout for a Proton Computed Tomography Prototype
