A lumped parameters model for cerebral blood flow in neonates and infants with patent ductus arteriosus
(Master thesis, 2019)En lumped parametermodell er utviklet for a ̊ studere dynamikken til en pulserende strømning i et sirkulasjonssystem, inkludert det cerebrale vaskulære nettverket. Denne modellen ble utviklet fra en forenklet anatomisk ... -
A minimal model for extragalactic high-energy particles
(Journal article; Peer reviewed, 2017)We explain in a unified way the experimental data on ultrahigh energy cosmic rays (UHECR) and neutrinos, using a single source class and obeying limits on the extragalactic diffuse gamma-ray background (EGRB). If UHECRs ... -
A Model for the Mixing of Black Carbon Aerosols and Mineral Dust Particles in the Atmosphere
(Master thesis, 2016)The process when freshly emitted black carbon particles are forming clusters and the mixing of these black carbon clusters and mineral dust particles has been simulated for a two-dimensional system. This has been done by ... -
A Monte Carlo Algorithm for Immiscible Two-Phase Flow in Porous Media
(Journal article; Peer reviewed, 2017)We present a Markov Chain Monte Carlo algorithm based on the Metropolis algorithm for simulation of the flow of two immiscible fluids in a porous medium under macroscopic steady-state conditions using a dynamical pore ... -
A Monte Carlo Study of the Criticality of the 3D XY Model
(Master thesis, 2015)In this master thesis the criticality of the 3D XY model with cubic anisotropy has been examined by the means of Monte Carlo simulation. The 3D XY model is a special case of the $O(n)$ spin-vector model which describe ... -
A nano-silicate material with exceptional capacity for CO2 capture and storage at room temperature
(Journal article; Peer reviewed, 2018)In order to mitigate climate change driven by the observed high levels of carbon dioxide (CO2) in the atmosphere, many micro and nano-porous materials are being investigated for CO2 selectivity, capture and storage (CCS) ... -
A new algorithm for remote sensing mesopause temperatures using the hydroxyl airlgow
(Master thesis, 2013)Ground based measurements of the hydroxyl airglow started in Trondheim (63.4 N, 10.4 E) 20. November 2012 using a linear InGaAs PDA detector covering the ∼1450-1650 nm wavelength range. The instrument have suc- cessfully ... -
A New Initialization Method for RETIS
(Master thesis, 2022)Monte Carlo-simuleringer (MC) i banerommet (eng. path space) er langt mer beregningskrevende enn MC-simuleringer i konfigurasjonsrommet fordi molekylærdynamikkbaner må genereres hvert MC-steg. Hvis initialtilstanden i ... -
A Numerical Study of Capillary and Viscous Drainage in Porous Media
(Dr. ingeniøravhandling, 0809-103X; 1999:131, Doctoral thesis, 1999)This work concentrates on the flow properties when one fluid displaces another fluid in a network of pores and throats. We consider the scale where individual pores enter the description and we use a network model to ... -
A Numerical Study of Transient Friction and Transient Friction Modelling in Ramp-up and Ramp-down Flow Conditions Similar to Pump Ramp-up and Valve Closure in Gas Transport Pipelines
(Master thesis, 2014)When gas is transported in long pipelines, computational models are used as tools to plan and to optimize hydraulic capacities. Because of the length of the pipelines the models are mostly one-dimensional (1D) which in ... -
A random Matrix Approach to collective Trends of falling and rising Stock Markets
(Master thesis, 2011)An inverse statistics analysis of one minute stock quotes from 492 large Europeancompanies has revealed the existence of a gain-loss asymmetry in thefollowing index. The gain-loss asymmetry differs from that observed for ... -
A Renormalization Group Procedure for Fiber Bundle Models
(Journal article; Peer reviewed, 2018)We introduce two versions of a renormalization group scheme for the equal load sharing fiber bundle model. The renormalization group is based on formulating the fiber bundle model in the language of damage mechanics. A ... -
A review of materials engineering in silicon-based optical fibre
(Journal article; Peer reviewed, 2017)Semiconductor optical fibre technologies have grown rapidly in the last decade and there are now a range of production and post-processing techniques that allow for a vast degree of control over the core material's ... -
A Scanning Tunneling Microscope for Point Contact Investigations of Magnetodynamics in FeMn/FeNi Bilayers
(Master thesis, 2009)This thesis presents the development of a scanning tunneling microscope purpose built for point contact investigations of magnetodynamics. The contributed changes include new measurement electronics, with 40-60% improvement ... -
A simple way for targeted delivery of an antibiotic: In vitro evaluation of a nanoclay-based composite
(Journal article; Peer reviewed, 2017)The sodium-modified form of fluorohectorite nanoclay (NaFh) is introduced as a potential drug carrier, demonstrating its ability for the controlled release of the broad-spectrum antibiotic Ciprofloxacin through in vitro ... -
A Simulated Annealing Approach to Electrical Resistivity Tomography
(Master thesis, 2018)In this study, a new approach to Electrical Resistivity Tomography (ERT) data inversion was investigated. ERT is a geophysical method for imaging the subsurface. An electrical current is injected into the surface, and the ... -
A Soft-Limit Theorem for the On-Shell Scattering Amplitudes Describing Processes Involving Massive Nambu-Goldstone Bosons
(Master thesis, 2017)In this thesis we consider systems where both Lorentz invariance and a continuous symmetry group G is explicitly broken by coupling a chemical potential µ to one of the generators Q of G. In such systems it is well known ... -
A Spectroscopic Study of in situ Magnetic Doping of Novel Layered Materials for Spintronics
(Master thesis, 2016)MoS2 is a layered material in the family of the transition metal dicalchogenides (TMDCs), which hosts interesting spin physics. Even though the TMDCs are nonmagnetic in their bulk form, a local breaking of inversion symmetry ... -
