A density-dependent failure criterion for concrete
(Journal article, 2016)This work focuses on the large effect of small secondary stresses on the compressive strength of concrete. The strength and especially the ductility of structural concrete members depend on local triaxial stress conditions ... -
A depth semi-averaged model for coastal dynamics
(Journal article, 2017)The present work extends the semi-integrated method proposed by Antuono and Brocchini [“Beyond Boussinesq-type equations: Semi-integrated models for coastal dynamics,” Phys. Fluids 25(1), 016603 (2013)], which comprises a ... -
A descriptive study of ten-year longitudinal changes in weight and waist circumference in the multi-ethnic rural Northern Norway. The SAMINOR Study, 2003-2014
(Journal article; Peer reviewed, 2020)The obesity epidemic is dynamic with varying secular trends and differences between countries and ethnic groups. The objective of this study was to describe the age- and sex-specific longitudinal changes in weight and waist ... -
A design methodology for resilience in fleets for service operations
(Chapter, 2016)In this paper, we present a new conceptual design methodology for increasing the resilience in complex operations involving a fleet of ships. The objective of the methodology is to support design decisions to reduce ... -
A Detached-Eddy-Simulation study: Proper-Orthogonal-Decomposition of the wake flow behind a model wind turbine
(Journal article; Peer reviewed, 2018)In times of intense renewable energy development, the planning of wind farms and the improvement of their total efficiency has become a major field of research. A precise analysis of the velocity deficit, fluctuation load ... -
A Developed Eco-Sourcing Tool Based on Model View Control Architecture for Small and Medium Enterprise
(Journal article; Peer reviewed, 2019)This study aims to develop an eco-sourcing tool grounded on Model View Control (MVC) architecture for Small and Medium Enterprise (SME) to enable clients’ select automobiles products online and order any automobile by just ... -
A diagram for capturing and predicting failure locations in notch geometries produced by additive manufacturing
(Journal article; Peer reviewed, 2020)In a recent work by the authors Solberg and Berto (2019), as-built notch geometries of Inconel 718 produced by selective laser melting was investigated under fatigue loading. One of the findings was that fatigue did not ... -
A Discovery of Quite Exceptional Proportions: Controversies in the Wake of Anders Nummedal’s Discoveries of Norway’s First Inhabitants
(Journal article; Peer reviewed, 2014)Around the beginning of the twentieth century archaeologists believed that Norway was not inhabited until the Late Stone Age. In 1909 two pieces of flint, found by the school-teacher Anders Nummedal, launched an extensive ... -
A discrete dopaminergic projection from the incertohypothalamic A13 cell group to the dorsolateral periaqueductal gray in rat
(Journal article; Peer reviewed, 2013)Several findings have indicated an involvement of dopamine in panic and defensive behaviors. The dorsolateral column of the periaqueductal gray (dlPAG) is crucially involved in the expression of panic attacks in humans and ... -
A discrete-modules-based frequency domain hydroelasticity method for floating structures in inhomogeneous sea conditions
(Journal article; Peer reviewed, 2017)Based on the three-dimensional (3D) potential theory and finite element method (FEM), this paper proposes a new numerical method for hydroelastic predictions of floating structures in inhomogeneous seabed and wave field ... -
A discussion of risk influencing factors for maritime accidents based on investigation reports
(Chapter, 2017)This paper reports findings from a review of investigation reports from maritime accidents. Based on a systematic analysis of 95 reports, we discuss a selection of typical causes and circumstances for serious maritime ... -
A displacement-free formulation for the Timoshenko beam problem and a corresponding isogeometric collocation approach
(Journal article; Peer reviewed, 2017)We present a reformulation of the classical Timoshenko beam problem, resulting in a single differential equation with the rotation as the only primal variable. We show that this formulation is equivalent to the standard ... -
A Distributed Algorithm for Scenario-based Model Predictive Control using Primal Decomposition *
(Journal article; Peer reviewed, 2018)In this paper, we consider the decomposition of scenario-based model predictive control problem. Scenario MPC explicitly considers the concept of recourse by representing the evolution of uncertainty by a discrete scenario ... -
A distributed anti-collision decision support formulation in multi-ship encounter situations under COLREGs
(Journal article; Peer reviewed, 2015)A multi-ship anti-collision decision support formulation is studied in a distributed and real time way. Under the general requirements from COLREGs rules and regulations, the performance of course alteration and changing ... -
A distributed architecture of L1 attrition
(Journal article; Peer reviewed, 2019) -
A Distributed Optimization Strategy for Large Scale Oil and Gas Production Systems
(Journal article; Peer reviewed, 2018)n this paper, we consider the problem of real-time optimization of an oil and gas production network. The production network is often made of several wells from different reservoir sections producing to a common processing ... -
A distributed parameter systems view of control problems in drilling
(Journal article; Peer reviewed, 2015)We give a detailed view of estimation and control problems raised by the drilling process where the distributed nature of the system cannot be ignored. In particular, we focus on the transport phenomena in Managed Pressure ... -
A dither-free extremum-seeking control approach using 1st-order least-squares fits for gradient estimation
(Journal article; Peer reviewed, 2014) -
A Domain with Non-plurisubharmonic Squeezing Function
(Journal article; Peer reviewed, 2018)We construct a strictly pseudoconvex domain with smooth boundary whose squeezing function is not plurisubharmonic. -
A domain-decomposition strategy for a compressible multi-phase flow interacting with a structure
(Journal article, 2014)The problem of a high-pressure gas cavity and its interaction with surrounding liquid and a close-by structure is examined numerically. Even though this is of interest in many practical applications, here, the focus is on ...
