Precipitation in an extruded AA7003 aluminium alloy: Observations of 6xxx-type hardening phases
(Journal article; Peer reviewed, 2019)Precipitation behaviour in an industrially extruded AA7003 alloy has been studied using Transmission Electron Microscopy (TEM) together with Differential Scanning Calorimetry (DSC). Air Cooling (AC) after solution heat ... -
Precipitation in multicomponent, lean, Al-Mg-Si alloys: A transmission electron microscopy study
(Doctoral thesis at NTNU;2016:266, Doctoral thesis, 2016)Aluminium alloys have a number of versatile applications, and there are numerous alloys in production today, where a variety of solute additions and heat treatments are applied. This work focusses on lean, age-hardenable ... -
Precipitation, mechanical properties and early slant ductile fracture in cyclic and naturally aged Al-Zn-Mg(-Cu) alloys
(Peer reviewed; Journal article, 2022)Natural and artificial ageing treatments are compared with ageing by cyclic deformation at room temperature. Atom probe tomography and transmission electron microscopy revealed that a fine distribution of GP-zones, was ... -

Prediction of a paramagnetic Meissner effect in voltage-biased superconductor/normal-metal bilayers
(Peer reviewed; Journal article, 2020)Conventional superconductors respond to external magnetic fields by generating diamagnetic screening currents. However, theoretical work has shown that one can engineer systems where the screening current is paramagnetic, ... -
Prediction of Protein Function using semantic Fingerprints - Multivariate Data Classification by Artificial Neural Networks involving dimensional Reduction
(Master thesis, 2016)In many fields of today's scientific research the amount of knowledge is far smaller than the amount of accessible data and often too limited to make meaningful analyses and draw reasonable conclusions. Hence, statistical ... -
Prediction of seakeeping abilities for the free-fall lifeboat FF1200
(Master thesis, 2012)In this thesis we have investigated seakeeping properties of Star CCM+. Star CCM+ is hoped to be used for simulations of the initial sailing phase of UMOE Schat Harding's new free fall lifeboat FF1200. It is a critical ... -
Preliminary in-situ study of FIB-assisted method for aluminium solid-state welding at the microscale
(Peer reviewed; Journal article, 2021)In situ studies allow real time monitoring and deep comprehension of phenomena. This approach has been applied to the current research for the development of a novel solid-state welding technique at the microscale. The ... -
Preon Models in Particle Physics
(Master thesis, 2014)We summarize the standard model and grand unified theories in light of group theoretical properties. We discuss selected classic and modern preon models. Finally, a schematic preon model for all three generations of ... -
Presence of negative entropies in Casimir interactions
(Journal article; Peer reviewed, 2016)Negative entropy in connection with the Casimir effect at uniform temperature is a phenomenon rooted in the circumstance that one is describing a nonclosed system, or only part of a closed system. In this paper we show ... -
Pressure Fluctuations and Correlations in Steady State two Phase Flow in Porous Media
(Master thesis, 2013)This thesis investigates the burst size distribution and pressurecorrelation profiles of steady state two phase flow in porous mediaat various capillary numbers and viscosity ratios. A network modelis used to simulate ... -
Pressure Fluctuations in Steady State Two-Phase Flow in Porous Media
(Master thesis, 2013)Several aspects of two-phase flow in porous are examined numerically.The burst size distributions in both the invasion phase and steady stateare computed; above a threshold, the steady state distribution is found tobe ... -
Pressure-induced 0-π transitions and supercurrent crossover in antiferromagnetic weak links
(Journal article, 2013)We compute self-consistently the Josephson current in a superconductor-antiferromagnet-superconductor junction using a lattice model, focusing on 0−π transitions occurring when the width of the antiferromagnetic region ... -
Pricing Put Options using Heston's Stochastic Volatility Model
(Master thesis, 2013)The Heston model is a partial differential equation which is used to price options and is a further developed version of the more famous Black-Scholes equation. Heston considers stochastic volatility which results in an ... -
Primary Porcine Brain Endothelial Cells as In Vitro Model to Study Effects of Ultrasound and Microbubbles on Blood-Brain Barrier Function
(Journal article; Peer reviewed, 2017)Focused ultrasound in the presence of microbubbles transiently and reversibly opens the blood-brain barrier (BBB) in rodents and humans thereby providing a time window for increased drug delivery into brain tissue. To get ... -
