Investigation fatigue crack initiation and propagation cruciform welded joints by extended finite element method (XFEM) and implementation SED approach
(Peer reviewed; Journal article, 2022)This study has used the strain energy density (SED) approach to evaluate the stress intensity factor (SIF) of cracked cruciform welded joints in Hardox 450 steel. A microstructural analysis was made of Hardox 450 steel ... -
Investigation into Norwegian Teachers’ Perspectives on the Use of Students' Mother Tongue in the EFL Classroom
(Journal article; Peer reviewed, 2018)This paper reports the results of a questionnaire-based study that examined Norwegian EFL teachers’ views on the use of students' mother tongue (MT) in teaching English as a foreign language (EFL). It focuses on the teachers’ ... -
Investigation into Phishing Risk Behaviour among Healthcare Staff
(Peer reviewed; Journal article, 2022)A phishing attack is one of the less complicated ways to circumvent sophisticated technical security measures. It is often used to exploit psychological (as as well as other) factors of human users to succeed in social ... -
An Investigation into Technological Potentials of Library Intralogistics Operations
(Chapter, 2023)The efficiency of operations in service-oriented organizations is amongst the primary objectives. Libraries are no exception in this context, and this goal becomes even more complex due to being a non-profitable entity. ... -
Investigation into the effect of simulating a 3D cylindrical fluidized bed reactor on a 2D plane
(Journal article; Peer reviewed, 2013)2D planar simulations of 3D cylindrical fluidized bed reactors are routinely carried out in order to reduce computational costs. The error involved in this simplification is largely unknown, however, and this study was ... -
Investigation of `glitches' in the energy spectrum induced by single-crystal diamond compound X-ray refractive lenses
(Peer reviewed; Journal article, 2018)Single-crystal diamond stands out among all the candidate materials that could be exploited to fabricate compound refractive lenses (CRLs) owing to its extremely stable properties. Among all related experimental features, ... -
Investigation of a Drum Controlled Cross-Adaptive Audio Effect for Live Performance
(Journal article; Peer reviewed, 2017)Electronic music often uses dynamic and synchronized digital audio effects that cannot easily be recreated in live performances. Cross-adaptive effects provide a simple solution to such problems since they can use multiple ... -
Investigation of a Francis turbine during speed variation: Inception of cavitation
(Peer reviewed; Journal article, 2020)Variable-speed operation of a hydro turbine is considered as an alternative option to meet fluctuating energy demand as it allows high-ramping rate. Cavitation can be a limiting factor to utilize the variable-speed technology ... -
Investigation of a new application for cellulose nanocrystals: a study of the enhanced oil recovery potential by use of a green additive
(Journal article; Peer reviewed, 2018)Cellulose nanocrystals (CNC) were investigated for use in a potential new application, enhanced oil recovery. Core flooding experiments were performed on outcrop sandstone cores using CNC particles dispersed in low salinity ... -
Investigation of AC and DC power distributions to seafloor mining equipment
(Chapter, 2017)The main goal of this paper is to study and compare different power distribution alternatives for subsea electrical components for deep-sea mining in the Norwegian Sea. Such application requires power delivery in the ... -
Investigation of an air-cushion supported solar island
(Chapter, 2018)A preliminary investigation of a low-weight carrying marine platform concept was conducted by means of experiments and approximate theories. The platform consists of a circular elastic tube with circular cross-section, ... -
Investigation of an Innovative Latent Heat Storage Concept in a Stovepipe
(Journal article; Peer reviewed, 2018)Latent heat storage (LHS) is a promising concept for small-scale batch combustion. One example is wood stoves, which rely on a batch combustion process that yields a transient heat production with high peak effect. A ... -
Investigation of an outbreak caused by antibiotic susceptible Klebsiella oxytoca in a neonatal intensive care unit in Norway
(Journal article; Peer reviewed, 2018)Abstract Aim Klebsiella spp. have been stated to be the most frequent cause of neonatal intensive care unit (NICU) outbreaks. We report an outbreak of Klebsiella oxytoca in a NICU at a tertiary care hospital in Norway ... -
Investigation of bubbling behavior in deep fluidized beds at different gas velocities using electrical capacitance tomography
