(Master thesis, 2024)I jakten på å forbedre sikkerheten og påliteligheten til komplekse industrielle systemer har teknologien for Prognostisk Helsestyring (PHM), spesielt dens komponenter for feildiagnose og prognose, funnet økende relevans i ... -
A comparative study between traditional topology optimization and lattice optimization for additive manufacturing
(Journal article; Peer reviewed, 2019)Topology optimization (TO) aids designers to come up with new ideas that would be impossible to be designed without this technology. However, the optimized results are usually characterized by high geometric complexity, ... -
A comparative study of beam element formulations for nonlinear analysis: corotatinal vs. geometrically exact formulations
(Chapter, 2017)In this work the geometrically exact three-dimensional beam theory has been used as basis for development of a family of isoparametric higher order large deformation curved beam elements. Geometrically exact three-dimensional ... -

A Comparative Tribocorrosion Study of Additive Manufactured and Wrought 316L Stainless Steel in Simulated Body Fluids
(Journal article; Peer reviewed, 2018)In this study, the corrosion and tribocorrosion behavior of additive manufactured (AM) 316L is investigated and compared to wrought 316L. The experiments were performed in both a 0.9 wt% NaCl solution and a simulated body ... -
A comparison between numerical and approximate methods for rapid calculation of NSIFs
(Journal article; Peer reviewed, 2019)To more rapidly predicting the integrity of components weakened by sharp notches, notch stress intensity factors (NSIFs) are usually evaluated. Many methods have been proposed evaluating NSIFs, ranging from the stress ... -
A Comparison of Hazards and Efficiencies of Conventional and Adaptive Control Algorithms Using Systems-Theoretic Process Analysis
(Journal article; Peer reviewed, 2019)Control systems are an important and increasingly complex part of most industrial and non-industrial systems. As such, identifying and handling associated risks is increasingly important. Systems- Theoretic Process Analysis ... -
A Comparison of Theoretical and Measured Pressure Losses Within a Drinking Water Treatment Plant
(Master thesis, 2016)Pressure loss and its effects on the resulting hydraulics within a drinking water treatment plant are extremely important aspects of design and operation. Pressure losses are important to monitor as they are the driving ... -
A comprehensive numerical investigation of the impact behaviour of an offshore wind turbine blade due to impact loads during installation
(Journal article, 2019)For installing offshore wind turbines into deep waters, use of floating crane vessels is essential. One of the major challenges is their sensitivity to wave-induced vessel and crane tip motions, which can cause the impact ... -
A computational approach to expose conversation dynamics in engineering design activities
(Journal article, 2017)In this paper, we apply a computational approach to expose conversation dynamics in design conversations. We apply this approach to a case study comprising of two sessions, with 300 speaker turns respectively. The resulting ... -
