Wavefront aberration correction in medical ultrasound imaging
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:165, Doctoral thesis, 2004)Medisinsk ultralydavbildning er et relativt rimelig verktøy som er i utstrakte bruk på dagens sykehus og tildels også legekontor. En underliggende antakelse ved dagens avbildningsteknikker er at vevet som skal avbildes i ... -
Waveguide asymmetric long-period grating couplers as refractive index sensors
(Peer reviewed; Journal article, 2020)A highly sensitive integrated photonic transducer is designed by utilizing asymmetric long-period gratings on a silicon waveguide. These gratings are formed by periodic perturbation of the waveguide width, leading to ... -
Wavelength and orientation dependent capture of light by diatom frustule nanostructures
(Peer reviewed; Journal article, 2015)The ecological success of diatoms is emphasized by regular blooms of many different species in all aquatic systems, but the reason behind their success is not fully understood. A special feature of the diatom cell is ... -
Wavelength conversion and supercontinuum generation in silicon optical fibers
(Journal article, 2018)This paper describes the state of the art in wavelength conversion and supercontinuum generation using glass-clad silicon core optical fibers. Such semiconductor fibers have enjoyed considerable attention due to their ... -
Wavelet based feature extraction and visualization in hyperspectral tissue characterization
(Journal article; Peer reviewed, 2014)Hyperspectral images of tissue contain extensive and complex information relevant for clinical applications. In this work, wavelet decomposition is explored for feature extraction from such data. Wavelet methods are simple ... -
Wavelet based Video coding with optical flow for motion compensation
(Master thesis, 2011)In broadcasting environments intra-only video coding with JPEG 2000 has shownto provide many desired features along with high picture quality. However, thereis no exploitation of temporal redundancy, which can reduce the ... -
Wavelet Techniques in Medical Imaging: Classification of UltraSound Images using the Windowed Scattering Transform
(Master thesis, 2014)In this thesis we will study wavelet techniques for image classification in ultrasound(US) images. The aim is to develop a method for classifying the degree of inflammation in finger-joints.We develop and apply the techniques ... -
Wavelets and irregular time series
(Master thesis, 2012)In this thesis we study time series containing pressure measurements from a three phase flow pipeline at the Ekofisk oil field. The pipeline transports a mixture of oil, water and gas from $15$ wells for approximately ... -
WaveRider - A high-intensity interval training exergame for exercise bikes
(Master thesis, 2022)Statistikk levert av New England Journal of Medicine viser at den norske befolkningen har et høyere nivå av overvekt enn flere europeiske land og de høyeste verdiene i Skandinavia. Studier viser at vi bruker mer tid bak ... -

Waves in Excitable Media
(Master thesis, 2012)This thesis is dedicated to the study of Barkley's equation, a stiff diffusion-reaction equation describing waves in excitable media. Several numerical solution methods will be derived and studied, range from the simple ... -
Waves Propagating on Fluids with Piecewise Constant Vorticity
(Master thesis, 2015)The purpose of this study was to find the dispersion relation for waves on an arbitrary current velocity profile approximated by N linear layers. Using a Stokes expansion to first order in the steepness parameter ka the ... -
Waves' numerical dispersion and damping due to discrete dispersion relation
(Chapter; Peer reviewed, 2014)In linear Rankine panel method, the discrete linear dispersion relation is solved on a discrete free-surface to capture the free-surface waves generated due to wave-body interactions. Discretization introduces numerical ... -
Wax Deposition as a Function of Flow Regimes
(Master thesis, 2018)As petroleum fluids flow in subsea pipelines, the fluids are cooled by the surrounding water. Many crude oils contain substantial amounts of wax molecules, and if the temperature of the fluids drops below the Wax Appearance ... -
Wax-Inhibitor Interactions Studied by Isothermal Titration Calorimetry and Effect of Wax Inhibitor on Wax Crystallization
(Journal article; Peer reviewed, 2017)Isothermal titration calorimetry is applied to investigate the interactions of polymeric pour-point depressants (PPDs) or asphaltenes with macrocrystalline wax in a model oil system. This represents a novel approach to ... -
Waxholm Space atlas of the rat brain hippocampal region: Three-dimensional delineations based on magnetic resonance and diffusion tensor imaging
(Journal article; Peer reviewed, 2015)Atlases of the rat brain are widely used as reference for orientation, planning of experiments, and as tools for assigning location to experimental data. Improved quality and use of magnetic resonance imaging (MRI) and ... -
The Way Forward
(Chapter, 2023)This chapter points to the way ahead by introducing five recommendations to meet the requirements set forward by the Stockholm+50 agenda. The requirements identify co-working as vital to addressing the planetary crisis of ... -
