Thermal performance of concrete with recycled aggregates from CDW plants
(Peer reviewed; Journal article, 2017)This investigation intends to analyse the thermal performance of concrete with recycled aggregates (RA) from construction and demolition waste (CDW) collected from several locations in Portugal. A total of 17 concrete mixes ... -
Decarbonizing primary steel production : Techno-economic assessment of a hydrogen based green steel production plant in Norway
(Peer reviewed; Journal article, 2022)High electricity cost is the biggest challenge faced by the steel industry in transitioning to hydrogen based steelmaking. A steel plant in Norway could have access to cheap, emission free electricity, high-quality iron ... -
Static quark-antiquark interactions at nonzero temperature from lattice QCD
(Peer reviewed; Journal article, 2022)flavor lattice QCD calculations. The study consists of two parts. The first investigates the properties of Wilson line correlators in Coulomb gauge and compares to predictions of hard-thermal loop perturbation theory. As ... -
Evolutionary Maintenance of the PTS2 Protein Import Pathway in the Stramenopile Alga Nannochloropsis
(Peer reviewed; Journal article, 2020)The stramenopile alga Nannochloropsis evolved by secondary endosymbiosis of a red alga by a heterotrophic host cell and emerged as a promising organism for biotechnological applications, such as the production of polyunsaturated ... -
Definition of reliability and maintenance concepts in oil and gas - validity aspects
(Peer reviewed; Journal article, 2020)International standards have a key role in establishing consistent terminology. Amongst these is the recently published and revised ISO standard on reliability and maintenance data collection and exchange, i.e. ISO 14224:2016. ... -
Application of short-range dual-Doppler lidars to evaluate the coherence of turbulence
(Peer reviewed; Journal article, 2016)Two synchronized continuous wave scanning lidars are used to study the coherence of the along-wind and across-wind velocity components. The goal is to evaluate the potential of the lidar technology for application in wind ... -
Numerical Investigation on Aerodynamic Characteristics of Dual-Rotor Wind Turbines
(Peer reviewed; Journal article, 2022)Improving power output and reducing costs are crucial to the sustainable development of offshore wind power. In the present study, a dual-rotor wind turbine (DRWT) is proposed to improve wind energy capture efficiency by ... -
A discussion on the implementation of the Polar Code and the STCW Convention’s training requirements for ice navigation in polar waters
(Peer reviewed; Journal article, 2022)In 2017, the International Maritime Organization (IMO) implemented the International Code for Ships Operating in Polar Waters (Polar Code), with mandatory requirements covering the Arctic and Antarctic Oceans. In this ... -
Thermalization of non-Abelian gauge theories at next-to-leading order
(Peer reviewed; Journal article, 2022)We provide the first next-to-leading-order (NLO) weak-coupling description of the thermalization process of far-from-equilibrium systems in non-Abelian gauge theory. We study isotropic systems starting from either over- ... -
Prediction of tensile strength in fused deposition modeling process using artificial neural network and fuzzy logic
(Peer reviewed; Journal article, 2022)Fused deposition modeling is a modern rapid prototyping technique that is used for swiftly replicating concept modeling, physical modeling, and end-of-line manufacture. Precision parameter selection is crucial for generating ... -
Barents Sea Oil and Gas 2025: Three Scenarios
(Chapter, 2015)What are some of the possible futures for Barents Sea oil and gas? This chapter draws upon the key trends and issues covered by the book’s thematic chapters and presents three scenarios on the prospects for Norwegian–Russian ... -
Method for reconstruction of axisymmetric capillary wave surface topography using inverse ray-tracing of refracted laser sheet
(Peer reviewed; Journal article, 2022)Capillary waves can be used to measure the fundamental fluid properties such as surface tension as well as, potentially, the viscosity of Newtonian fluids. This requires the measurement of various wave parameters, mainly ... -
OpenIaC: open infrastructure as code - the network is my computer
(Peer reviewed; Journal article, 2022)Modern information systems are built fron a complex composition of networks, infrastructure, devices, services, and applications, interconnected by data flows that are often private and financially sensitive. The 5G networks, ... -
Perturbative thermal QCD: Formalism and applications
(Peer reviewed; Journal article, 2020)In this review article, we discuss the current status and future prospects of perturbation theory as a means of studying the equilibrium thermodynamic and near-equilibrium transport properties of deconfined QCD matter. We ... -
Dynamic Analysis and Extreme Response Evaluation of Lifting Operation of the Offshore Wind Turbine Jacket Foundation Using a Floating Crane Vessel
(Peer reviewed; Journal article, 2022)The jacket is the most widely-used fixed foundation for offshore wind turbines due to its superior strength and low installation cost in relatively deep waters. Floating crane vessels are commonly used to install jacket ... -
Integrated management of safety and security in Seveso sites - sociotechnical perspectives
