Performance of dynamic safety barriers-Structuring, modelling and visualization
(Master thesis, 2014)The main objective of this master thesis is to discuss performance of dynamic safety barriers. A comprehensive literature review is performed in order to get understanding what dynamic safety barrier is. Three different ... -
Performance Supervised Plant-Wide Process Monitoring in Industry 4.0: A Roadmap
(Peer reviewed; Journal article, 2021)The intensive research and development efforts directed towards large-scale complex industrial systems in the context of Industry 4.0 indicate that safety and reliability issues pose significant challenges. During online ... -
Performance Testing Real-Time Robot Communication for a Constraint-Based Robotic Welding System
(Master thesis, 2021)I denne masteroppgaven gjennomføres det en sanntid-ytelsestest for moto biblioteket. Dette er et Python bibliotek lagd for å styre Motoman roboter fra YASKAWA ved bruk av både banepunk og sanntidsstyring. Ytelsestestingen ... -
PESTOL - Framework for «Project Evaluation on Strategic, Tactical and Operational Levels»
(Peer reviewed; Journal article, 2016)The paper focuses on the development of the ex-post conceptual holistic framework for Project Evaluation on Strategic, Tactical and Operational Levels, the PESTOL model, by reviewing different definitions of project success ... -
Phase formation during heating of amorphous nickel-based bni-3 for joining of dissimilar cobalt-based superalloys
(Peer reviewed; Journal article, 2021)Phase transformations and the melting range of the interlayer BNi-3 were investigated by differential scanning calorimetry, which showed three stages of crystallization during heating. There were three exothermic peaks ... -
Phase Type Modelling for Approximation of the Geometric Brownian Motion
(Chapter, 2020)A geometric Brownian motion (GBM) is a continuous-time stochastic process in which the logarithm of the randomly varying quantity follows a Brownian motion with drift. The GBM allows to model degradation where the increase ... -
Phenomenological approach towards modelling the acoustic emission due to plastic deformation in metals
(Journal article; Peer reviewed, 2019)Considering acoustic emission (AE) as a phenomenon reflecting the elastic energy dissipation process in deforming metals, a simple yet self-consistent model is proposed to account for the AE behaviour accompanying ... -
A phenomenological model of deformation twinning kinetics
(Peer reviewed; Journal article, 2021)Inspired by the classical Olson and Cohen model for martensitic phase transformations, a simple phenomenological model of the deformation twinning kinetics is proposed with account for twin-twin interactions. The model was ... -
A phenomenological model of twinning-mediated strain hardening
(Peer reviewed; Journal article, 2020)We present a model of strain-hardening in materials with twinning-mediated plasticity. While the model is largely phenomenological, it was motivated by microstructural considerations and can be claimed to be physically ... -
Phosphorus management in the Baltic Sea historic evidence and future options
(Master thesis, 2012)Phosphorus being one of the essential elements for all forms of life is also a finite resource. The extensive use of Phosphorus in anthropogenic activities has lead to high nutrient load in surface waters causing eutrophication. ... -
Photogrammetry-based 3D scanning for supporting design activities and testing in early stage product development
(Peer reviewed; Journal article, 2021)In the early stages of product development and design, physical prototypes are designed and built from varying materials with the aim of providing valuable experience and decision support for the project team. In the era ... -
Photography - A New Tool in Needfinding
(Chapter, 2015)In this paper we are proposing the use of photography as a dedicated tool to capture latent needs and create anchor points for future solutions in engineering design. We are grounded in user centric design. Based on a ... -
Photography - Bridging the Gap between Needfinding and Visual Thinking
(Master thesis, 2015)Founding on the pre-master project Photography a new tool in needfinding (Wulvik et al., 2015) as starting point and based on theory from the fields of needfinding and visual thinking, an explorative experiment has ... -
