Animal study assessing safety of an acoustic coupling fluid that holds the potential to avoid surgically induced artifacts in 3D ultrasound guided operations

Jakola, Asgeir S; Jørgensen, Arve; Selbekk, Tormod; Michler, Ralf-Peter; Solheim, Ole; Torp, Sverre Helge; Sagberg, Lisa Millgård; Aadahl, Petter; Unsgård, Geirmund (Journal article; Peer reviewed, 2014)

Background Use of ultrasound in brain tumor surgery is common. The difference in attenuation between brain and isotonic saline may cause artifacts that degrade the ultrasound images, potentially affecting resection grades ...

Animasjon i naturfagsundervisningen

(Bachelor thesis, 2022)

Animasjonsfilmens status i akademia

Kvamsøe, Kristian V. (Bachelor thesis, 2019)

Denne bacheloroppgåva er ein historisk og teoretisk studie av animasjonsfilmen som medium, med mål om å belyse grunnane til at den har vorte marginalisert i akademia, samt fått eit stempel blant sjåarar som hovudsakleg for ...

Anime-esque in the West: How LEGO Monkie Kid Uses Anime-esque Traits as a Tool for Emphasis

Berg, Halldis (Bachelor thesis, 2023)

I de siste årene har anime gått inn i mainstream-bevisstheten som en del av aktuell popkultur. Denne populariseringen har fått mange til å hente inn inspirasjon fra de visuelle egenskapene den har. Denne artikkelen vil ...

Animering av eksplosjoner i sanntid

Ek, Lars Andreas; Vistnes, Rune (Master thesis, 2007)

Eksplosjoner er en viktig del av mange spill. Men eksplosjoner er hurtige og veldig turbulente fenomener som vanskelig lar seg simulere bra, spesielt for sanntidsapplikasjoner. Vi presenterer en metode for animering av ...

Anion Exchange Membrane Water Electrolysis from Catalyst Design to the Membrane Electrode Assembly

Faid, Alaa Yahia Abulgheit A.; Sunde, Svein (Peer reviewed; Journal article, 2022)

Anion exchange membrane (AEM) electrolysis aims to combine the benefits of alkaline electrolysis, such as stability of the cheap catalyst and advantages of proton-exchange membrane systems, like the ability to operate at ...

Anisotropic and controllable Gilbert-Bloch dissipation in spin valves

Kamra, Akashdeep; Polishchuk, Dmytro; Korenivski, Vladislav; Brataas, Arne (Peer reviewed; Journal article, 2019)

Spin valves form a key building block in a wide range of spintronic concepts and devices from magnetoresistive read heads to spin-transfer-torque oscillators. We elucidate the dependence of the magnetic damping in the free ...

Anisotropic contribution to the van der Waals and the Casimir-Polder energies for CO2 and CH4 molecules near surfaces and thin film

Thiyam, Priyadarshini; Parashar, Prachi; Shajesh, K. V.; Persson, Clas; Schaden, Martin; Brevik, Iver Håkon; Parsons, Drew F.; Milton, Kimball A.; Malyi, Oleksandr; Boström, Mathias (Journal article; Peer reviewed, 2015)

In order to understand why carbon dioxide ( CO 2 ) and methane ( CH 4 ) molecules interact differently with surfaces, we investigate the Casimir-Polder energy of a linearly polarizable CO 2 molecule and an isotropically ...

Anisotropic depth migration of converted wave data, inversion of multicomponent data to estimate elastic parameters at the seafloor and one-dimensional data-driven inversion

Helgesen, Hans Kristian (Doktoravhandlinger ved NTNU, 1503-8181; 2008:210, Doctoral thesis, 2006)

The increasing demand for oil and gas in the world today drives the need for new and improved methods for identifying hydrocarbon prospects. The petroleum industry uses information about the subsurface in the exploration ...

Anisotropic diffusion and the cosmic ray anisotropy

Kachelriess, Michael (Journal article; Peer reviewed, 2019)

We argue that the diffusion of cosmic rays in the Galactic magnetic field has to be strongly anisotropic. As a result, the number of CR sources contributing to the local CR flux is strongly reduced. The CR density is ...

Anisotropic Diffusion for Depth Estimation in Shape from Focus Systems

Ahmad, Bilal; Farup, Ivar; Floor, Pål Anders (Chapter, 2024)

Shape from focus is a monocular method that uses the camera’s focus as the primary indicator for depth estimation. The initial depth map is usually improved by penalizing the L2 regularizer as a smoothness constraint, which ...

Anisotropic failure modes of high-strength aluminium alloy under various stress states

Fourmeau, Marion; Børvik, Tore; Benallal, A; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2013)

The influence of stress state and plastic anisotropy on the fracture behaviour of a rolled AA7075-T651 aluminium plate under quasi-static loading conditions is studied both experimentally and numerically. Material tests ...

Anisotropic fluid diffusion in carbon fiber reinforced composite rods: Experimental, analytical and numerical study

Gagani, Abedin; Krauklis, Andrejs; Echtermeyer, Andreas (Journal article; Peer reviewed, 2018)

Carbon fiber composite plastic (CFRP) rods immersed in water present a pronounced anisotropic diffusion behavior. Understanding and predicting this behavior is important as the mechanical properties of the material are ...

Anisotropic in-plane dielectric and ferroelectric properties of tensile-strained BaTiO3 films with three different crystallographic orientations

Ræder, Trygve Magnus; Holstad, Theodor Secanell; Nylund, Inger-Emma; Glaum, Julia; Einarsrud, Mari-Ann; Meier, Dennis; Grande, Tor (Peer reviewed; Journal article, 2021)

Ferroelectric properties of films can be tailored by strain engineering, but a wider space for property engineering can be opened by including crystal anisotropy. Here, we demonstrate a huge anisotropy in the dielectric ...

Anisotropic long-range spin transport in canted antiferromagnetic orthoferrite YFeO3
