(Master thesis / Masteroppgave, 2015)In this master thesis digital readout systems for radiation detection and mea- surement has been studied and designed. The project was split in two where one student developed analog front end electronics, and the other ...
-
(Master thesis / Masteroppgave, 2021)The multi-Needle Langmuir Probe (m-NLP) instrument is an electron density sensor made for sounding rockets and satellites. It is capable of a much higher sampling rate and spacial resolution compared to a traditional single ...

(Master thesis / Masteroppgave, 2018)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)At the time of energy transition, it is important to be able to predict the effects of fluid overpressures in different geological scenarios as these can lead to the development of hydrofractures and dilating high-porosity ...
-
(Doctoral thesis / Doktoravhandling, 2013)This thesis presents a study of fracture formation in low permeability rocks induced by generation of fluid or gas during chemical reaction. In nature, primary migration of hydrocarbons, i.e. generation of oil and gas from ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Across the field of education research there has been an increased focus on the development, critique, and evaluation of statistical methods and data usage due to recently created, very large datasets and machine learning ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The first direct observation of gravitational waves in 2015 has led to an increased public interest in topics of general relativity (GR) and astronomy. Physics teachers and educators respond to this interest by introducing ...
-
(Master thesis / Masteroppgave, 2021)The mystery of dark matter (DM) has intrigued scientists for many decades. The type of DM particles that has been studied the most is Weakly Interacting Massive Particles (WIMPs). These particles are assumed to have been ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)In high-energy collisions, the spatio-temporal size of the particle production region can be measured using the Bose–Einstein correlations of identical bosons at low relative momentum. The source radii are typically extracted ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)A bstract Relic density calculations of dark matter freezing out from the primordial plasma have reached a high level of sophistication, with several numerical tools readily available that match the observationally ...
-
Frequency and phase relations of entangled photons observed by a two-photon interference experiment (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)An entangled photon experiment has been performed with a large variation of the temperature of the nonlinear crystal generating the entangled pair by spontaneous downconversion. The photon pairs are separated by a nonpolarizing ...

-
(Master thesis / Masteroppgave, 2023)This master thesis centers on the exploration of a frequency delta-sigma modulator (FDSM) with ultra-low power supply down to 80 mV for the analog circuitry. The FDSM is configured with ring voltage controlled oscillator ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The surface morphology of faults controls the spatial anisotropy of their frictional properties and hence their mechanical stability. Such anisotropy is only rarely studied in seismology models of fault slip, although it ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Multiphase flows involving granular materials are complex and prone to pattern formation caused by competing mechanical and hydrodynamic interactions. Here we study the interplay between granular bulldozing and ...
-
(Master thesis / Masteroppgave, 2017)Summary: Lung cancer is a disease which has poor prognosis and is very life-threatening, as the survival rate five years after being diagnosed is merely 20%.This is the reason why the scientific community continues research ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)When learning chemistry, students must learn to extract chemical information from mathematical expressions. However, chemistry students’ exposure to mathematics often comes primarily from pure mathematics courses, which ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Despite the widespread use of current‐source density (CSD) analysis of extracellular potential recordings in the brain, the physical mechanisms responsible for the generation of the signal are still debated. While the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Transition metal antimonides form a class of intermetallic compounds, which has drawn considerable attention due to their potential applications in various fields. However, the formation of nanostructures containing multiple ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Self-assembled molecular monolayer (SAMM) doping has great potential in state-of-the-art nanoelectronics with unique features of atomically precision and nondestructive doping on complex 3D surfaces. However, it was recently ...
