Analysis of hydrocarbon leaks and verification as an operational barrier
(Journal article; Peer reviewed, 2015)Prevention of hydrocarbon (HC) leaks is important; they are the most critical precursor events that may lead to major accidents, such as the Piper Alpha catastrophe in 1988. The number of HC leaks on offshore production ... -
Analysis of Iceberg Drift Trajectories Using the Multivariate Empirical Mode Decomposition
(Journal article; Peer reviewed, 2018)In this study we show how to detect and extract the tidal and inertial oscillation from iceberg velocity data by using the multivariate empirical model decomposition. Due to the similar frequencies of both oscillations in ... -
Analysis of individual quality scores of different image distortions
(Peer reviewed; Journal article, 2022)In this paper, we study individual quality scores given by different observers for various image distortions (saturation, contrast, and color quantization) at different levels. We created a database that contains a total ... -
Analysis of Intra-Tumoral Macrophages and T Cells in Non-Small Cell Lung Cancer (NSCLC) Indicates a Role for Immune Checkpoint and CD200-CD200R Interactions
(Peer reviewed; Journal article, 2021)Lung cancer is the leading cause of cancer-related death worldwide, accounting for nearly one-fifth of all cancer-related deaths. Immunotherapy with immune checkpoint inhibitors has become one of the most promising approaches ... -
Analysis of Lifting Operation of a Monopile Considering Vessel Shielding Effects in Short-crested Waves
(Journal article, 2016)This paper addresses numerical simulations of the lifting operation of an offshore wind turbine monopile foundation, considering both the shielding effects of the vessel and the spreading of the waves. A numerical model ... -
Analysis of lifting operation of a monopile for an offshore wind turbine considering vessel shielding effects
(Journal article; Peer reviewed, 2014)This study addresses numerical simulations of the lifting operation of a monopile for an offshore wind turbine with a focus on the lowering process. A numerical model of the coupled system of the monopile and vessel is ... -
Analysis of loads, motions and cavity dynamics during freefall wedges vertically entering the water surface
(Journal article; Peer reviewed, 2015)In this paper, theoretical models are developed and numerical methods are used to analyze the loads, motions and cavity dynamics for freefall wedges with different deadrise angles vertically entering the water surface at ... -
Analysis of magnetic forces and vibration in a converter-fed synchronous hydrogenerator
(Chapter, 2017)This paper investigates the influence of converter-fed operation on magnetic forces and radial vibration in a hydrogenerator. Flux density distribution is computed using time-stepping finite element (FE) analysis and used ... -
Analysis of Megavariate Data in Functional Omics
(Chapter, 2020)Over the latest decades, there has been a rapid development of laboratory techniques used for analyzing the pathways from the genes to the final physiology of an organism. The study of all genes in an organism is defined ... -
An analysis of mentor and mentee roles in a pre-service teacher education program: a Norwegian perspective on the future mentor role
(Peer reviewed; Journal article, 2022)Globally, pre-service teacher education has experienced a practice turn where there is now greater focus on practice in schools and more attention is being paid to mentoring and the role of the school-based mentors. In ... -
Analysis of MMC Dynamics in DQZ Coordinates for Vertical and Horizontal Energy Balancing Control
(Chapter, 2018)This paper presents a control system implementation in dqz-coordinates for equalizing the average energies stored in each arm of a Modular Multilevel Converter (MMC); a control objective that is typically referred to as ... -
Analysis of monthly and daily profiles of DHW use in apartment blocks in Norway
(Peer reviewed; Journal article, 2020)Profiles of domestic hot water (DHW) use give valuable information for achieving energy saving in buildings. In this article, analysis of monthly and hourly profiles in apartment blocks in Norway was performed. The aim was ... -
Analysis of Natural Gas engine de-loading on LNG fuelled vessels
(Journal article; Peer reviewed, 2015)Onboard the Norwegian Coast Guard vessel KV Bergen, as well as other LNG fuelled vessels, there has been reports of a sudden fall in the fuel tank system pressure, resulting in de-loading of the NG engines. This study ... -
