(Peer reviewed; Journal article, 2023)We demonstrate that ab-initio calculations in QCD at high densities offer significant and nontrivial information about the equation of state of matter in the cores of neutron stars, going beyond that which is obtainable ... -
Acceptance of wind power development and exposure – Not-in-anybody’s-backyard
(Peer reviewed; Journal article, 2020)Despite a large stated-preference (SP) literature on wind power externalities, few SP studies employ a case-control approach to examine whether people’s acceptance of new wind power developments and renewable energy ... -
Accountability Requirements in the Cloud Provider Chain
(Journal article; Peer reviewed, 2018-04)In order to be responsible stewards of other people’s data, cloud providers must be accountable for their data handling practices. The potential long provider chains in cloud computing introduce additional accountability ... -
Actuator and sensor fault estimation based on a proportional multiple‐integral sliding mode observer for linear parameter varying systems with inexact scheduling parameters
(Peer reviewed; Journal article, 2020)This article proposes an approach for the estimation of states, actuator, and sensor faults in nonlinear systems represented by a polytopic linear parameter varying (LPV) system with inexact scheduling parameters. In the ... -
Adaptive machine learning-based surrogate modeling to accelerate PDE-constrained optimization in enhanced oil recovery
(Peer reviewed; Journal article, 2022)In this contribution, we develop an efficient surrogate modeling framework for simulation-based optimization of enhanced oil recovery, where we particularly focus on polymer flooding. The computational approach is based ... -
Adaptive mesh refinement in locally conservative level set methods for multiphase fluid displacements in porous media
(Peer reviewed; Journal article, 2023)Multiphase flow in porous media often occurs with the formation and coalescence of fluid ganglia. Accurate predictions of such mechanisms in complex pore geometries require simulation models with local mass conservation ... -
Adaptive Methods for Revenue Model learning of a Slice Broker in the Presence of Adversaries
(Peer reviewed; Journal article, 2024)In the fifth-generation (5G) of mobile networks, Multi-Access Edge Computing (MEC) refers to the deployment of computing resources closer to the end-users for improved service delivery. In the context of 5G MEC, the slice ... -
Adaptive non-conform behaviour in accident investigations in the road based heavy goods transport sector
(Peer reviewed; Journal article, 2021)This paper presents findings from a study of 29 accident investigations in the heavy goods transportation sector in Norway. The investigations are performed by the Norwegian Safety Investigation Authority (NSIA). The NSIA ... -
Additive manufacturing best practices and its impact on supply chain performance through structural equation modelling: A case study in Ethiopian footwear industry
(Peer reviewed; Journal article, 2023)The aim of this study is to analyze the effects of additive manufacturing (AM) best practices on supply chain (SC) performance. The study developed conceptual framework with four AM best practice as independent variables ... -
Additive Multi-Effort Contests
(Peer reviewed; Journal article, 2020-03)Impact on rent seeking occurs even when a player exerts only one effort. This contrasts with models of multiplicative efforts with impact on rent seeking only when a player exerts all its available efforts. An analytical ... -
Addressing challenges in uncertainty quantification: The case of geohazard assessments
(Peer reviewed; Journal article, 2023)We analyse some of the challenges in quantifying uncertainty when using geohazard models. Despite the availability of recently developed, sophisticated ways to parameterise models, a major remaining challenge is constraining ... -
Addressing human error when collecting failure cause information in the oil and gas industry: A review of ISO 14224:2016
(Peer reviewed; Journal article, 2020-02)The international standard ISO 14224 provides key guidance on how to achieve quality information about equipment failures for decision-making in the oil and gas industry, including specific guidance on data collection ... -
Adhesive forces between two cleaved calcite surfaces in NaCl solutions: The importance of ionic strength and normal loading
(Journal article; Peer reviewed, 2018-12-15)The mechanical strength of calcite bearing rocks is influenced by pore fluid chemistry due to the variation in nano-scale surface forces acting at the grain contacts or close to the fracture tips. The adhesion of two ... -
