An Interactive Tool for Collaboration and Knowledge Sharing of Customer Needs in the Conceptual Phase
(Peer reviewed; Journal article, 2020)This paper aims to research how the use of an interactive tool can facilitate collaboration, knowledge sharing and enhance the understanding of customer needs in conceptual phase at a global shipbuilding company. An effective ... -
Introduction to Non Commutative Algebraic Geometry
(Journal article; Peer reviewed, 2015)Ordinary commutative algebraic geometry is based on commutative polynomial algebras over an algebraically closed field k. Here we make a natural generalization to matrix polynomial k-algebras which are non-commutative ... -
Joint Detection and Decoding of Mixed-ADC Large-Scale MIMO Communication Systems with Protograph LDPC Codes
(Peer reviewed; Journal article, 2021)Nowadays, large-scale multiple-input multiple-output (LS-MIMO) with low-resolution analog-to-digital converters (ADCs) is a favorable transmission scheme for 5G and beyond wireless networks to reduce the power consumption ... -
The Journey Towards Computational Materials
(Peer reviewed; Journal article, 2021)This research explores the journey towards computational materials by looking at metals, powder-based materials, composite materials and smart materials. This journey can not be explored without considering the processes ... -
Managing Risk and Opportunities in Complex Projects
(Chapter, 2019)Projects is the preferred model for one-of-a-kind production. Projects may be difficult to manage due to complexity and many involved stakeholders. Stakeholders are a major source of uncertainty. Uncertainty may be both ... -
Mathematical modelling of fluid flow in electromagnetically stirred weld pool
(Peer reviewed; Journal article, 2021)In this paper, a mathematical model has been proposed to study the relationship between electromagnetic stirring (EMS) weld parameters and the mode of fluid flow on grain refinement of AA 6060 weldments. For this purpose, ... -
Measurement disturbance and conservation laws in quantum mechanics
(Peer reviewed; Journal article, 2023)Measurement error and disturbance, in the presence of conservation laws, are analysed in general operational terms. We provide novel quantitative bounds demonstrating necessary conditions under which accurate or non-disturbing ... -
A Model for an Effective Learning Process in Higher Education: An Example from Three User Cases
(Peer reviewed; Journal article, 2022)Knowledge is the most important asset in education. Knowledge Management has been the focus for many years in higher education. Recently, universities have embraced innovative processes that could foster a better learning ... -
Modelling and Simulation of Detection Rates of Emergent Behaviours in System Integration Test Regimes
(Peer reviewed; Journal article, 2021)System level testing generally lacks coverage due to cost of performing realistic tests on the “system as a whole”. This lack in test coverage gives rise to seemingly emergent aviour at system level. The interactions between ... -
The Need for Systems Awareness to Support Early-Phase Decision-Making—A Study from the Norwegian Energy Industry
(Peer reviewed; Journal article, 2021)In this paper, we explore the need to improve systems awareness to support early-phase decision-making. This research uses the Norwegian energy industry as context. This industry deals with highly complex engineering systems ... -
Nonclassical photon statistics in two-tone continuously driven optomechanics
(Peer reviewed; Journal article, 2021)In cavity optomechanics, single-photon detection of Raman scattered photons can be a useful tool for observing nonclassical features of both radiation and motion. While this tool has been employed in experiments with pulsed ... -
On the contribution of learning analytics to the quality of hybrid course delivery
(Peer reviewed; Journal article, 2021)This paper discusses the use of the learning analytics that are commonly available to teachers in general, but particularly to the academic staff at the University of South-Eastern Norway (USN). The importance of the ... -
Optimal Operation of Stand-Alone Microgrid Considering Emission Issues and Demand Response Program Using Whale Optimization Algorithm
(Peer reviewed; Journal article, 2021)Microgrids are new technologies for integrating renewable energies into power systems. Optimal operation of renewable energy sources in standalone micro-grids is an intensive task due to the continuous variation of their ... -
Performance Analysis of Protograph LDPC Codes Over Large-Scale MIMO Channels With Low-Resolution ADCs
