Report on the 44th European Conference on Information Retrieval (ECIR 2022): The First Major Hybrid IR Conference
(Journal article, 2022)The 44th European Conference on Information Retrieval (ECIR’22) was held in Stavanger, Norway. It represents a landmark, not only for being the northernmost ECIR ever, but also for being the first major IR conference in a ... -
Neighbourhood conditions and quality of life among local and immigrant population in Norway
(Peer reviewed; Journal article, 2022)This paper explores the relationship between the quality of life and neighbourhood characteristics among immigrant and local population in Storhaug (Stavanger) and Grünerløkka (Oslo), two Norwegian neighbourhoods. The ... -
Thoughts about the utility of perturbative QCD in the cores of neutron stars – contribution to a roundtable discussion on neutron stars and QCD
(Peer reviewed; Journal article, 2022)In this contribution, I discuss the utility that perturbative QCD offers in studying the matter in the cores of neutron stars. I discuss the reasons why perturbative QCD can constrain the equation of state at densities far ... -
A novel design approach for estimation of extreme load responses of a 10-MW floating semi-submersible type floating wind turbine
(Peer reviewed; Journal article, 2022)Offshore structures are constructed to withstand extreme wind and wave-induced loads, so studying these extreme loads is vital as it allows offshore structures, e.g., wind turbines, to be designed and operated with minimal ... -
An investigation of the effects and consequences of combining Expanding Dual Pin with radial spherical plain bearings
(Peer reviewed; Journal article, 2022)An expanding pin locks the pin assembly to its supports and bearings and prevents any relative movements between the surfaces in contact. In this study, the diameter changes of the bearing inner ring as a function of the ... -
Further insight into the genetic diversity of Entamoeba coli and Entamoeba hartmanni
(Peer reviewed; Journal article, 2022)Despite the species' wide distribution, studies of the genetic diversity within Entamoeba coli and Entamoeba hartmanni remain limited. In the present study, we provide further insight into the genetic diversity of both ... -
A level set approach to Ostwald ripening of trapped gas bubbles in porous media
(Peer reviewed; Journal article, 2022)Ostwald ripening of gas bubbles is a thermodynamic process for mass transfer, which is important for both foam enhanced oil recovery and geological CO2 storage. We present a methodology for simulating Ostwald ripening of ... -
Towards a Taylor-Carleman bilinearization approach for the design of nonlinear state-feedback controllers
(Peer reviewed; Journal article, 2022)The Carleman bilinearization is an approach that performs an exact conversion of a finite-dimensional nonlinear system into an infinite-dimensional bilinear system. A finite-dimensional system is later obtained through a ... -
The complex heavy-quark potential in an anisotropic quark-gluon plasma — Statics and dynamics
(Peer reviewed; Journal article, 2022)We generalize a complex heavy-quark potential model from an isotropic QCD plasma to an anisotropic one by replacing the Debye mass mD with an anisotropic screening mass depending on the quark pair alignment with respect ... -
Bayesian inference of real-time dynamics from lattice QCD
(Peer reviewed; Journal article, 2022)The computation of dynamical properties of nuclear matter, ranging from parton distribution functions of nucleons and nuclei to transport properties in the quark-gluon plasma, constitutes a central goal of modern theoretical ... -
Design of shifting output-feedback controllers for LPV systems subject to time-varying saturations
(Peer reviewed; Journal article, 2022)This paper considers the problem of designing a shifting output-feedback controller for polytopic linear parameter-varying (LPV) systems subject to time-varying saturations. By means of the LPV framework and the use of the ... -
An improved delay and state observer for SISO LTI systems withknown delay lower bound
(Peer reviewed; Journal article, 2022)It is known that the presence of delays hinders the performance achievable by a feedback control system, and it can even lead to closed-loop instability if not considered during the design. For this reason, predictors are ... -
Mechanical Performance of Polymeric ARGF-Based Fly Ash-Concrete Composites: A Study for Eco-Friendly Circular Economy Application
(Peer reviewed; Journal article, 2022)At present, low tensile mechanical properties and a high carbon footprint are considered the chief drawbacks of plain cement concrete (PCC). At the same time, the combination of supplementary cementitious material (SCM) ... -
A Novel Technique for Temporarily Repair and Improvement of Damaged Pin Joint Support Bores
(Peer reviewed; Journal article, 2022)Damaged support bores due to wear and ovality can be critical for a machine and its operation, in addition to representing a safety problem and risk of pin breakage. It can be a costly operation to perform the required ... -
Dynamic Analysis of Splash-zone Crossing Operation for a Subsea Template
(Peer reviewed; Journal article, 2022)Subsea templates are steel structures used to support subsea well components. Normally, offshore crane vessels are employed to install them to the target location on the seabed. Crossing the splash-zone during the lowering ... -
Prediction of permeability of tight sandstones from mercury injection capillary pressure tests assisted by a machine-learning approach

Pressure Build-Up in Closed Wells During Kick Migration and Fluid Compressibility Effects
(Chapter, 2022)If a kick is migrating in a closed well, this will lead to pressures building up in the well. It has earlier been shown that for Non-Newtonian fluids, suspension effects will make it impossible to deduce a unique gas ... -
Reaction kinetics determined from core flooding and steady state principles for Stevns Klint and Kansas chalk injected with MgCl2 brine at reservoir temperature
(Peer reviewed; Journal article, 2022)A methodology is presented for determining reaction kinetics from core flooding: A core is flooded with reactive brine at different compositions with injection rates varied systematically. Each combination is performed ... -
Immigration and its effects on European urban areas
(Peer reviewed; Journal article, 2022)Immigration is a highly discussed topic in Europe. Flows of immigrants with different ethnic and social background into cities often occupy urban areas. This arrival of immigrant population to cities is based on certain ... -
Cyclic production of biocompatible few-layer graphene ink with in-line shear-mixing for inkjet-printed electrodes and Li-ion energy storage
(Peer reviewed; Journal article, 2022)The scalable production of two-dimensional (2D) materials is needed to accelerate their adoption to industry. In this work, we present a low-cost in-line and enclosed process of exfoliation based on high-shear mixing to ...
