On the role of pre-exposure time and corrosion products in stress-corrosion cracking of ZK60 and AZ31 magnesium alloys
(Peer reviewed; Journal article, 2021)Pre-exposure of Mg alloys to corrosive media causes their embrittlement, which has been long associated with diffusible hydrogen penetrating into the metal. The time of the pre-exposure was suggested to promote embrittlement ... -
On the shear band velocity in metallic glasses: A high-speed imaging study
(Journal article; Peer reviewed, 2018)Development of localised shear bands (SB) in bulk metallic glassy (BMG) alloys was investigated by a high-speed microscopic imaging technique. The velocities of SBs propagating by a progressive mechanism were found to be ... -
On the Substitution of Aluminium for Copper Conductors in Battery Systems
(Doctoral theses at NTNU;2024:86, Doctoral thesis, 2024)Aluminium’s electrical conductance per-unit mass and per-unit cost is unequalled. These are two desirable properties in a world undergoing widespread electrification. Electricity generation, transmission and utilisation ... -
On the suitability of insourced Additive Manufacturing for spare parts management
(Peer reviewed; Journal article, 2022)Additive Manufacturing (AM) has recently emerged as a promising technique in spare parts manufacturing. Unlike conventional manufacturing (CM) techniques, AM can lead to a reduction in inventory levels, particularly when ... -
On the terms violating the custodial symmetry in multi-Higgs-doublet models

The main contributions are principles and software relating to the control of production ... -
An Open-Source Python-Based Boundary-Element Method Code for the Three-Dimensional, Zero-Froude, Infinite-Depth, Water-Wave Diffraction-Radiation Problem
(Journal article; Peer reviewed, 2021)In this paper, a new open-source implementation of the lower-order, 3-D Boundary Element Method (BEM) of solution to the deep-water, zero Froude-number wave-body interaction problem is described. A validation case for ... -
Operation-oriented reliability and availability evaluation for onboard high-speed train control system with dynamic Bayesian network
(Journal article; Peer reviewed, 2018)The reliability and availability of the onboard high-speed train control system are important to guarantee operational efficiency and railway safety. Failures occurring in the onboard system may result in serious accidents. ... -
Operational capacity planning in warehousing
(Master thesis, 2023)Kapasitetsplanlegging er ofte utfordrende for lager på grunn av svingende etterspørsel og mangel på viktig informasjon. Nøyaktig informasjon om tilgjengelig arbeidsstyrke og arbeidsbelastning er avgjørende for at lageret ... -
Operational data-driven prediction for failure rates of equipment in safety instrumented systems: A case study from the oil and gas industry
(Journal article; Peer reviewed, 2019)Safety instrumented systems are frequently deployed to reduce the risk associated with industrial activities, such as those in the oil and gas industry. A key requirement for safety-instrumented systems in standards like ... -
Operational integration in a craft-oriented small enterprise
(Journal article, 2017)Purpose Many leisure boat manufacturers have thrived on designing and building highly customized boats based on longstanding traditions of craftsmanship. To achieve efficient value chains, it is not enough to optimize ... -
