The number of syllables per phrase in songs of Great Tits Parus major decreases with high levels of anthropogenic noise and at northern latitudes
(Peer reviewed; Journal article, 2023)Birds may sing to defend a territory and to attract a mate. However, despite many studies clear conclusions remain on how ecological conditions affect the song, such as physical obstacles that may reduce the sound transmission, ... -
Numbers, Governance, Health: A Norwegian Case of Statistics and Documentation Production
(Journal article; Peer reviewed, 2013)This paper follows the documents (texts, numbers) of a statistics system called IPLOS. IPLOS is intended to coordinate, control, standardize and stabilize municipal care services in Norway and generate statistical knowledge ... -
Numeric work: The efforts of calculation actors to make numbers count in climate and energy policy
(Peer reviewed; Journal article, 2022)Policy documents suggest that quantitative information is important in the development of climate and energy policy. This is supported by quantitative studies research into the use of numbers in governance, which tends to ... -
Numerical analysis of a vessel- shaped offshore fish farm
(Journal article; Peer reviewed, 2018)The aquaculture industry is aiming to move fish farms from nearshore areas to open seas because of many attractive advantages in the open water. However, one major challenge is to design the structure to withstand the ... -
Numerical analysis of boundary conditions in a Lagrangian particle model for vertical mixing, transport and surfacing of buoyant particles in the water column
(Journal article; Peer reviewed, 2019)Lagrangian particle models are used for many applications in the ocean sciences, including transport modelling of oil spills, fish eggs and larvae, plastics, and sediment particles. In the context of oil spill modelling, ... -
Numerical analysis of buckling failure in flexible pipe armor wires
(Journal article; Peer reviewed, 2015)Flexible pipes may be exposed to high axial compression and bending during deep-water installation. As the compression force is mainly sustained by the tensile armor layers, this may result in localized lateral or radial ... -
Numerical Analysis of Combined VIV and Slug Flow in Time Domain
(Chapter; Peer reviewed, 2016)Vortex induced vibrations (VIV) and slug flow are two important aspects for marine risers conveying a multiphase flow, and should be carefully examined due to the influence on the fatigue life of the structure. This article ... -
Numerical analysis of dynamic response of jacket structures subject to slamming forces by breaking waves
(Journal article; Peer reviewed, 2017)The present study numerically analyzed the dynamic behavior of 3D framed structures subject to impulsive slamming forces by violent breaking waves. The structures were modeled using multiple lumped masses for the vertical ... -
Numerical Analysis of Flow across Brush Elements Based on a 2-D Staggered Tube Banks Model
(Journal article; Peer reviewed, 2021)n order to improve efficiency in turbomachinery, brush seal replaces labyrinth seals widely in the secondary air system. A 2-d staggered tube bank model is adopted to simulate the gas states and the pressure character in ... -
Numerical analysis of fluid-added parameters for the torsional vibration of a Kaplan turbine model runner
(Journal article; Peer reviewed, 2017)The impact of fluid on the runner of a hydraulic turbine is a recurrent problem. Fully coupled fluid–structure simulations are extremely time-consuming. Thus, an alternative method is required to estimate this interaction ... -
Numerical analysis of local and global responses of an offshore fish farm subjected to ship impacts
(Journal article; Peer reviewed, 2019)Due to limited nearshore areas and great impact to local ecosystems, the aquaculture industry is moving the fish farms into more exposed sea regions where the environmental conditions are much more severe. Like other ... -
Numerical analysis of mixed-mode rupture propagation of faults in reservoir-caprock system in CO2 storage
(Journal article, 2018)Injection-induced seismicity and caprock integrity are among the most important concerns in CO2 storage operations. Understanding and minimizing fault/fracture reactivation in the first place, and rupture growth/propagation ... -
Numerical Analysis of NREL 5MW Wind Turbine: A Study Towards a Better Understanding of Wake Characteristic and Torque Generation Mechanism
(Journal article; Peer reviewed, 2016)With the increased feasibility of harvesting offshore wind energy, scale of wind turbines is growing rapidly and there is a trend towards clustering together higher number of turbines in order to harvest maximum yield and ... -
Numerical analysis of pit-to-crack transition under corrosion fatigue using a stochastic pit generation algorithm
(Chapter, 2023)In numerical corrosion fatigue studies, the complex pit morphology is often idealized using an overly simplified geometry with a smooth surface because of the difficulties involved in modelling defects with the irregular ... -
