Nonequilibrium attractor in high-temperature QCD plasmas
(Peer reviewed; Journal article, 2020)We establish the existence of a far-from-equilibrium attractor in weakly coupled gauge theory undergoing one-dimensional Bjorken expansion. We demonstrate that the resulting far-from-equilibrium evolution is insensitive ... -
A Multiscale Approach for Whole-Slide Image Segmentation of five Tissue Classes in Urothelial Carcinoma Slides
(Peer reviewed; Journal article, 2020)In pathology labs worldwide, we see an increasing number of tissue samples that need to be assessed without the same increase in the number of pathologists. Computational pathology, where digital scans of histological ... -
Numerical simulations of the sliding impact between an ice floe and a ship hull structure in ABAQUS
(Peer reviewed; Journal article, 2022)This paper studies the hull structural responses of a steel grillage subjected to sliding ice loads, which have been rarely investigated in the literature. Sliding ice loads are modelled using nonlinear finite element ... -
An evaluation of different RANS turbulence models for simulating breaking waves past a vertical cylinder
(Peer reviewed; Journal article, 2021)The purpose of the present study is to evaluate the performance of different turbulence models for predicting the interaction between breaking waves and a vertical cylinder based on the volume of fluid (VOF) method. Six ... -
A Multi-Agent Reinforcement Learning Architecture for Network Slicing Orchestration
(Chapter, 2021)The Network Slicing (NS) paradigm is one of the pillars of the future 5G networks and is gathering great attention from both industry and scientific communities. In a NS scenario, physical and virtual resources are partitioned ... -
Modelling Melanin Biosynthesis Pathway with Petri Nets
(Peer reviewed; Journal article, 2021)Melanin is a UV radiation-absorbing pigment that is responsible for variation in skin color. The melanin synthesis pathway is a series of chemical reactions that lead to the formation of melanin. By creating a mathematical ... -
Early and Late Time Analytical Solutions for Co-current Spontaneous Imbibition and Generalized Scaling
(Peer reviewed; Journal article, 2020)We propose an explicit analytical solution for 1D cocurrent (COC) spontaneous imbibition (SI) in which a core is exposed to water (inlet) and oil (outlet). The system is described using an advection-capillary diffusion ... -
Effects of mooring line breakage on dynamic responses of grid moored fish farms under pure current conditions
(Peer reviewed; Journal article, 2021)Due to the lack of sheltered area, Norwegian fish farms are expanding to more exposed and remote sites. The severe environmental conditions in exposed sites can increase the risk of structural failure during aquaculture ... -
Extracting Petri Modules From Large and Legacy Petri Net Models
(Peer reviewed; Journal article, 2020)Petri nets, even though very useful for modeling of discrete event systems, suffer from some weaknesses such as huge size, huge state space, and slow in simulation. Due to the huge state space, model checking a Petri net ... -
Climate change and small pelagic fish price volatility
(Peer reviewed; Journal article, 2020)Price volatility, an indicative measure of price uncertainty, is an important factor influencing fisheries cost, income, food security, and pressure on fish stocks. An increase in price volatility means that prices are ... -
Validation and assessment of different RANS turbulence models for simulating turbulent flow through an orifice plate
(Peer reviewed; Journal article, 2021)In the present study, numerical simulations using different Reynolds-Averaged Navier–Stokes (RANS) turbulence models are carried out to investigate the turbulent flow through the orifice plate at Reynolds number (Re) of ... -
Estimation in uncertain switched systems using a bank of interval observers: local vs glocal approach
(Peer reviewed; Journal article, 2020)This paper discusses some issues related with the design of a bank of interval observers for uncertain switched systems, in which several sources of uncertainty are considered: parametric uncertainties, unknown disturbances, ... -
Introducing a New Toolbox for Theory of Connection
(Peer reviewed; Journal article, 2020)These days, graphs and graph theory is being used for modelling, simulation, and performance analysis of many physical systems, as physical systems are becoming more and more connected. However, ca. 75 years ago, Gabriel ... -
CFD investigation of blind-tee effects on flow mixing mechanism in subsea pipelines
(Peer reviewed; Journal article, 2022)Blind tees are widely used in subsea pipelines to enhance the mixing conditions of oil and gas products, but their structural design still relies on experience. In this paper, a series of numerical investigations have been ... -
Promoting effect of Fe on supported Ni catalysts in CO2 methanation by in situ DRIFTS and DFT study
(Peer reviewed; Journal article, 2020-12)Bimetallic NiFe catalysts have emerged as a promising alternative to the traditional Ni catalysts for CO2 methanation. However, the promoting effect of Fe on the bimetallic catalysts remains ambiguous. In this study, a ... -
Data-Driven Approaches Tests on A Laboratory Drilling System
(Peer reviewed; Journal article, 2020)In recent years, considerable resources have been invested to exploit vast amounts of data that get collected during exploration, drilling and production of oil and gas. Data-related digital technologies potentially become ... -
Drilling data quality improvement and information extraction with case studies
(Peer reviewed; Journal article, 2020)Data analytics is a process of data acquiring, transforming, interpreting, modelling, displaying and storing data with an aim of extracting useful information, so that decision-making, actions executing, events detecting ... -
Wind turbines designed for easy installation
(Peer reviewed; Journal article, 2020)The costs of installation, intervention/maintenance and decommissioning of fixed bottom, founded offshore wind turbine concepts are unreasonably high when using state of the art technology. For such wind turbine concepts, ... -
