(Master thesis / Masteroppgave, 2014)This thesis explores the use of bioimpedance measurements within the field of electrosurgery. A standard monopolar electrosurgery setup has been utilized in order to discriminate between the characteristic impedance of the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)A phase-field model of a crystalline material is introduced to develop the necessary theoretical framework to study plastic flow due to dislocation motion. We first obtain the elastic stress from the phase-field crystal ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Dispersion forces such as van der Waals forces between two microscopic particles, the Casimir-Polder forces between a particle and a macroscopic object, or the Casimir force between two dielectric objects are well studied ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The injection of a reactive fluid into an open fracture may modify the fracture surface locally and create a ramified structure around the injection point. This structure will have a significant impact on the dispersion ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The Casimir-Lifshitz torque between two biaxially polarizable anisotropic planar slabs is shown to exhibit a nontrivial sign reversal in its rotational sense. The critical distance ac between the slabs that marks this ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)X-ray emission under electron-channelling conditions is used to distinguish between a non-centrosymmetric half-Heusler and a centrosymmetric full-Heusler crystal. For TiCo 1.5+ xSn the space-group determination based on a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Heart rate variability (HRV) has become an increasingly popular index of cardiac autonomic control in the biobehavioral sciences due to its relationship with mental illness and cognitive traits. However, the intraindividual ...
-
(Master thesis / Masteroppgave, 2007)In this study we take advantage of the slow, smooth rotation of the strong magnetic fields in interplanetary magnetic clouds to identify transitions between particle precipitation/plasma convection states of the magnetosphere ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)We have used a combination of optical absorption and electrical conductivity measurements to study the effect of the main donor on small polarons in rutile TiO2 single crystals rendered n-type conductive by hydrogenation ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)Incorporation of beryllium (Be) and tellurium (Te) dopants in epitaxially grown Al0.9Ga0.1As0.06Sb0.94 layers was investigated. Carrier concentrations and mobilities of the doped layers were obtained from room temperature ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The proposed Compact Linear Collider (CLIC) uses a high intensity, low energy drive beam to produce the RF power needed to accelerate a lower intensity main beam with 100 MV/m gradient. This scheme puts stringent requirements ...
-
(Doctoral thesis / Doktoravhandling, 2018)This thesis describes the development of a dual-mode optical power detector, where two measurement principles are combined into one device. The dual-mode detector combines the principles of thermal detection and photo-electrical ...
-
(Master thesis / Masteroppgave, 2010)Abstract Positron emission tomography (PET) is a medical imaging technique widely used for cancer diagnostics. The objective of this study was to investigate whether dynamic 18F-FDG PET imaging could be used to characterize ...
-
(Master thesis / Masteroppgave, 2011)FDG PET/CT scans from eleven patients with grade III or IV soft tissue sarcomas where obtained. Nine of the patients where liposarcomas, one was a schwannoma and one was a myxoid liposarcoma. Four of the patients were ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The potential and density wake behind a finite-sized object in a magnetized collisionless plasma flow is studied with self-consistent numerical simulations. With increasing magnetization of the plasma, the standard picture ...
