Will (or can) people pay for headache care in a poor country?
(Journal article; Peer reviewed, 2012)We asked whether attempts to introduce headache services in poor countries would be futile on grounds of cost and unsustainability. Using data from a population-based survey in the Republic of Georgia, an exemplary poor ... -
Will an implementation of “Joy of Life in Nursing Homes” have positive effect for the work culture? A comparison between two Norwegian municipalities
(Journal article; Peer reviewed, 2021) -
Will borealization of Arctic tundra herbivore communities be driven by climate warming or vegetation change?
(Peer reviewed; Journal article, 2021)Poleward shifts in species distributions are expected and frequently observed with a warming climate. In Arctic ecosystems, the strong warming trends are associated with increasing greenness and shrubification. Vertebrate ... -

Williams Syndrome neuroanatomical score associates with GTF2IRD1 in large-scale magnetic resonance imaging cohorts: A proof of concept for multivariate endophenotypes
(Journal article; Peer reviewed, 2018)Despite great interest in using magnetic resonance imaging (MRI) for studying the effects of genes on brain structure in humans, current approaches have focused almost entirely on predefined regions of interest and had ... -
Wind affecting berthing operations
(Peer reviewed; Journal article, 2020)ABSTRACT: Almost every voyage culminates in a manoeuvre to berth the ship safely along a quay or wharf. During this phase a ship is affected by a number of factors, one of them being wind. This paper seeks to understand ... -
Wind and soil model influences on the uncertainty in fatigue of monopile supported wind turbines
(Peer reviewed; Journal article, 2022)Several alternative engineering models are available for the use in analysis of offshore wind turbines. However, it is not always clear which of the models will yield the most accurate or sufficiently conservative results. ... -
Wind deflection analysis of railway catenary under crosswind based on nonlinear finite element model and wind tunnel test
(Peer reviewed; Journal article, 2022)This paper evaluates the railway catenary's wind deflection under crosswind based on wind tunnel experiments and a nonlinear finite element model. A catenary model is constructed based on the absolute nodal coordinate ... -
Wind Estimation with Multirotor UAVs
(Peer reviewed; Journal article, 2022)Unmanned Aerial Vehicles (UAVs) have benefited from a tremendous increase in popularity over the past decade, which has inspired their application toward many novel and unique use cases. One of them is the use of UAVs in ... -
Wind farm control - Part I: A review on control system conceptsand structures
(Journal article; Peer reviewed, 2021)Wind farm control design is a recently new area of research that has rapidly become a key enabler for the development of large wind farm projects and their safe and efficient connection to the power grid. A comprehensive ... -
Wind farm voltage dip measurements
(Journal article; Peer reviewed, 2014)This paper is based on continuous measurements of voltages and currents from three wind farms for a period of 1 year, and the focus is on voltage dips. The purpose is to get an overview of the characteristics and rate of ... -
Wind Field Variability in Complex Terrain: Lessons from the Hardanger Bridge
(Chapter; Peer reviewed, 2019)Along the Coastal Highway E39 in the western coast of Norway, Norwegian Government is planning to build several extreme bridges spanning from 1.5 to 5 km. The region is typically mountainous with deep fjords seeping inland. ... -
Wind in Complex Terrain - Lidar Measurements for Evaluation of CFD Simulations
(Journal article; Peer reviewed, 2018)Computational Fluid Dynamics (CFD) is widely used to predict wind conditions for wind energy production purposes. However, as wind power development expands into areas of even more complex terrain and challenging flow ... -
Wind power - An assault on local landscapes or an opportunity for modernization?
(Journal article; Peer reviewed, 2012)Wind power development has produced controversies in many places. Some people see wind power as a sustainable source of energy, others see it as destroying nature and landscapes. The opposition to wind power is often ... -
Wind power plant grid-forming control and influences on the power train and power system oscillation
(Chapter, 2022)In future power systems, wind power plants are supposed to contribute in the voltage and frequency stability of the grid. For this purpose, the control strategy of the wind power-frequency converter system needs to change ... -
Wind pressure coefficients for roof ventilation purposes
(Journal article; Peer reviewed, 2018)Wind pressure coefficients (cp) are important inputs for analytical calculations of wind load. The aim of this research is to investigate wind pressure coefficients on a test house located in Norway in order to pave the ... -
Wind tunnel experiments on wind turbine wakes in yaw: effects of inflow turbulence and shear
(Journal article; Peer reviewed, 2018)The wake characteristics behind a yawed model wind turbine exposed to different customized inflow conditions are investigated. Laser Doppler anemometry is used to measure the wake flow in two planes at x∕D = 3 and x∕D = 6, ... -
Wind tunnel experiments on wind turbine wakes in yaw: redefining the wake width
(Journal article; Peer reviewed, 2018)This paper presents an investigation of wakes behind model wind turbines, including cases of yaw misalignment. Two different turbines were used and their wakes are compared, isolating effects of boundary conditions and ... -
Wind tunnel investigation on the effect on the turbine tower on wind turbines wake symmetry
(Journal article; Peer reviewed, 2017)In wind farms, the wake of the upstream turbines becomes the inflow for the downstream machines. Ideally, the turbine wake is a stable vortex system. In reality, because of factors like background turbulence, mean flow ... -
Wind tunnel study on power output and yaw moments for two yaw-controlled model wind turbines
