Evaluating the suitability of RAS culture environment for rainbow trout and Atlantic salmon: A ten-year progression of applied research and technological advancements to optimize water quality and fish performance
(Doctoral thesis, 2020)Over the last several decades, recirculating aquaculture systems (RAS) have become a viable technology for the production of high-value food-fish. In Norway, for example, many Atlantic salmon smolt farms are now using RAS, ... -
Evaluating the utility of a Novel Harvest Control Rule in the management of long-lived sporadically recruiting species through Management Strategy Evaluation
(Master thesis, 2019-08-16)Fish species that exhibit sporadic recruitment, late maturity and that are long-lived, can be difficult to manage. The issue arises from the high variability in stock dynamics. Where there are significant interannual ... -
Evaluating two numerical advection schemes in HYCOM for eddy-resolving modelling of the Agulhas Current
(Ocean Science, Journal article, 2009-06-02)A 4th order advection scheme is applied in a nested eddy-resolving Hybrid Coordinate Ocean Model (HYCOM) of the greater Agulhas Current system for the purpose of testing advanced numerics as a means for improving the model ... -
Evaluating vascular visualization methods for pre-operative planning in the mesentery
(Master thesis, 2021-11-26)In this thesis I evaluate and compare a selection of vascular visualization methods with the help of surgeons. Vessel topology is highly varied, and individuals may have extra or "missing" branches, changes in connectivity, ... -
Evaluation and design of readout electronics for electron and proton detectors
(Master thesis, 2017-06-16)Researchers at Birkeland center of space science have initiated a project where the precipitating flux of energetic electrons and protons into the middle atmosphere will be measured. An instrument will be attached to a low ... -
Evaluation and Improvement of Machine Learning Algorithms in Drug Discovery
(Master thesis, 2022-06-01)Drug discovery plays a critical role in today’s society for treating and preventing sickness and possibly deadly viruses. In early drug discovery development, the main challenge is to find candidate molecules to be used ... -
An evaluation of 0-group abundance indices of Barents Sea fish stocks
(Peer reviewed; Journal article, 2009-01-23)The International 0-group fish survey in the Barents Sea (1965-2002) aimed to give initial indication of the recruiting year class strengths. Since 2003 the 0-group survey has been a part of a Joint Norwegian-Russian ... -
Evaluation of a deep neural network for acoustic classification using simulated echo sounder data
(Master thesis, 2020-06-16)An important part of fisheries acoustics is the classification of fish species. Sound waves are transmitted through water to detect fish species, and the echoes returning from the fish are categorized to be used for fish ... -
Evaluation of a eukaryote phylogenetic microarray for environmental monitoring of marine sediments
(Journal article; Peer reviewed, 2020)Increased exploitation of resources in sensitive marine ecosystems emphasizes the importance of knowledge regarding ecological impacts. However, current bio-monitoring practices are limited in terms of target-organisms and ... -
Evaluation of a sub-kilometre NWP system in an Arctic fjord-valley system in winter
(Journal article; Peer reviewed, 2020)Terrain challenges the prediction of near-surface atmospheric conditions, even in kilometre-scale numerical weather prediction (NWP) models. In this study, the ALADIN-HIRLAM NWP system with 0.5 km horizontal grid spacing ... -
Evaluation of analytical strategies for quantifying selected polyphenols in feed production: from ingredient to fish.
(Master thesis, 2023-09-30)Polyphenols are an extensive group of compounds with important antioxidant properties, whose industrial use has shown a continuous increase in the last years. Their utilization in aquaculture is becoming progressively ... -
Evaluation of black soldier fly larvae meal as a functional feed ingredient in Atlantic salmon (Salmo salar) under farm-like conditions
(Journal article; Peer reviewed, 2023)Atlantic salmon (Salmo salar) were fed diets containing black soldier fly larvae (BSFL) meal at two inclusion levels for 13 months in open sea-cages. BSFL meal replaced plant-based ingredients and dietary insect meal ... -
Evaluation of different wind fields for the investigation of the dynamic response of offshore wind turbines
(Journal article; Peer reviewed, 2020)As the size of offshore wind turbines increases, a realistic representation of the spatiotemporal distribution of the incident wind field becomes crucial for modeling the dynamic response of the turbine. The International ... -
Evaluation of Gaussian wake models under different atmospheric stability conditions: Comparison with large eddy simulation results
(Journal article; Peer reviewed, 2020)The calculation of the velocity deficit in the wake of individual wind turbines is a fundamental part of the wind farm analysis. A good approximation of the wake deficit behind a single wind turbine will improve the power ... -
Evaluation of harvest control rules: simple one-parameter versus complex multi-parameter strategies
(Master thesis, 2004)Harvest control rules (HCR) are sets of well-defined rules that can be used for determining annual fish catch quotas or effort. If a management policy can be expressed as a HCR, then the HCR provides means to determine the ... -
Evaluation of Methane and Water Structure at a Hematite Surface - A Hydrate Prevention Perspective
(Master thesis, 2017-09-25)In Norway oil and gas is found in reservoirs below the North Sea and the Barents Sea. When this is transported through pipelines it is exposed to temperatures and pressures in the hydrate stability zone. If sufficient ... -
