(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2005)The orientation relationship between ferroelastic domains in LaNbO4 (with 0.5 at.% Sr) is studied by selected area electron diffraction and high-resolution electron microscopy. At room temperature the domains are related ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract The seismic waves emitted during granular flows are generated by different sources: high frequencies by interparticle collisions and low frequencies by global motion and large scale deformation. To unravel these ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)Silicon (Si) is an efficient n-type dopant in gallium oxide (Ga2O3)—an ultra-wide bandgap semiconductor promising in a number of applications. However, in spite of the technological importance for device fabrication, the ...
-
(Doctoral thesis / Doktoravhandling, 2021)In his annus mirabilis, Albert Einstein published several important works that would strongly affect the future of physics. Among these was a work on Brownian motion – the random motion of small particles suspended in a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We study the dynamics of active nematic films on a substrate driven by active flows with or without the incompressible constraint. Through simulations and theoretical analysis, we show that arch patterns are stable in the ...
-
(Master thesis / Masteroppgave, 2022)In this thesis, we study active particles with focus on statistical properties of trapping time near a boundary. Active particles have a self-propelled force that drives the system out of equilibrium. The trapping time is ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Adsorption and assembly of colloidal particles at the surface of liquid droplets are at the base of particle-stabilized emulsions and templating. Here we report that electrohydrodynamic and electro-rheological effects in ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Calls for renewal of physics education include more varied learning activities and increased focus on qualitative understanding and history and philosophy of science (HPS) aspects. We have studied an innovative approach ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Background The purpose of this study was to investigate acute normal tissue responses in the head and neck region following proton- or X-irradiation of a murine model. Materials and methods Female C57BL/6J mice were ...

An AD5940-based instrument for bioimpedance spectroscopy and electrochemical sensingRestricted Access (Master thesis / Masteroppgave, 2021)As a low-cost, non-destructive analysis technique, bioimpedance has lately seen a broad range of utilization in different areas. This has resulted in an increased necessity for portable and inexpensive instrumentation. ...
-
(Master thesis / Masteroppgave, 2011)Denne oppgaven har sett på metoder for kompensasjon av friksjon i et Harmonic Drive gear som sitter på main azimuth aksen av en observasjonsplattform. Det har blitt sett på teorien bak friksjon med tanke på kompensasjon ...
-
(Master thesis / Masteroppgave, 2010)Denne oppgaven gikk ut på å lage en matematisk modell av et fly som hadde varierende stabilitet i forhold til angrepsvinkelen. Deretter ble det utviklet en adaptiv regulator som ga en raskere referanseforfølging enn en ...
-
(Master thesis / Masteroppgave, 2005)ABSTRACT There is a considerable and growing interest in broadband system for providing high capacity communications and broadcasting, through for example high speed Internet. Because of the large bandwidth available in ...
-
(Master thesis / Masteroppgave, 2019)WLAN (Wireless local area network ), also known as Wi-Fi has gained lots of attention during the past two decades due to its promising capabilities, ease of installation and low-cost of access points (APs), which offers ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Power-law attenuation in elastic wave propagation of both compressional and shear waves can be described with multiple relaxation processes. It may be less physical to describe it with fractional calculus medium models, ...

(Master thesis / Masteroppgave, 2014)
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)The mechanical strength of calcite bearing rocks is influenced by pore fluid chemistry due to the variation in nano-scale surface forces acting at the grain contacts or close to the fracture tips. The adhesion of two ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Real-time simulations of laser-driven electron dynamics contain information about molecular optical properties through all orders in response theory. These properties can be extracted by assuming convergence of the power ...
