Application of the Linear Eddy Model - A Study of Differential Diffusion in Turbulent Hydrogen-Rich Jets
(Master thesis, 2018)Differential diffusion effects in turbulent reactive and non-reactive problems based on hydrogen-rich fuels are not yet fully investigated. Through use of a Fortran implementa-tion of the Linear Eddy Model (LEM) ... -
Applications of Deep Neural Networks in Pulse Design with Parallel Transmission for Ultra-High Field MRI
(Master thesis, 2020)To hovedmål er undersøkt i denne oppgaven, som begge består av å prediktere komplekse vekter for parallelltransmisjon (PTx) for en 8-kanals transmit (Tx) 32-kanal mottak (Rx) Nova hodespole på en Simenes Magneton 7T med ... -
Applications of the Goldstone equivalence theorem to scattering and decay processes
(Master thesis, 2018)We study applications of the Goldstone boson equivalence theorem to decay and scattering processes, exemplifying the broken gauge theory structure of electroweak interactions. Apart from interest on theoretical grounds, ... -
Applikasjon av fokusert ionestråle (FIB) og skanning elektronmikroskop (SEM) for karakterisering av vev, celler og biomaterialer.
(Master thesis, 2011)Dette prosjektet har den intensjon å utforske karakteriseringsmuligheter med fokusert ionestråle (FIB) kombinert med skanning elektronmikroskop (SEM). Aspekter ved prøvepreparering, bilde prosessering har blitt diskutert. ... -
Applying generative adversarial networks for anomaly detection in hyperspectral remote sensing imagery
(Master thesis, 2018)Automatic anomaly detection has previously been implemented on hyperspectral images by use of different statistical methods with good results. We apply a machine learning method using generative adversarial networks (GAN) ... -
Approaches to Numerical Simulations of Causal Sets
(Master thesis, 2018)This project found mixed results for the class of so-called Feynman posets, partially ordered sets with a maximum vertex degeneracy of three. Sets that admit "Y" shaped vertices (so-called "no holes" posets) pass several ... -
Approaching Quantization in Macroscopic Quantum Spin Hall Devices through Gate Training
(Journal article; Peer reviewed, 2019)Quantum spin Hall edge channels hold great promise as dissipationless one-dimensional conductors.However, the ideal quantized conductance of2e2=his only found in very short channels-in contradictionwith the expected ... -
Approaching the Limits of Aspect Ratio in Free-Standing Al2O3 3D Shell Structures
(Peer reviewed; Journal article, 2022)Nanoscale free-standing membranes are used for a variety of sensors and other micro/nano-electro-mechanical systems devices. To tune performance, it is indispensable to understand the limits of aspect ratios achievable. ... -
Approximate analysis concerning wave-power absorption by hydrodynamically interacting buoys
(Doktor ingeniøravhandling (Trondheim);234, Doctoral thesis, 1982) -
Approximating Haze in Reflection - Approximate expressions for two-dimensional randomly rough surfaces
(Master thesis, 2015)We give a definition of haze in reflection from two-dimensional surfaces and study this quantity for Gaussian randomly rough surfaces. A simplified model of light scattering, assuming a scalar incident plane wave, the ... -
Artificial intelligence-based automatic segmentation for breast cancer radiotherapy
(Master thesis, 2020)Bakgrunn og formål: Nøyaktig inntegning av målvolum og risikoorganer er avgjørende for resultatet av pasientbehandling med stråleterapi. Manuell inntegning av strukturer er kjent som den største usikkerheten i stråletera ... -
Aspects of QCD thermodynamics through scalar field theory and NJL models
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:188, Doctoral thesis, 2011) -
Aspects related to variability of radiative cooling by NO in lower thermosphere, TEC and O/N2 correlation, and diffusion of NO into mesosphere during the Halloween storms
(Peer reviewed; Journal article, 2022)Nitric Oxide is a very important trace species which plays a significant role acting as a natural thermostat in Earth’s thermosphere during strong geomagnetic activity. In this paper, we present various aspects related to ... -
Assessing RF-Induced Heating of Orthopedic Implants in Ultra-High Field MRI: Influencing Factors and the Effect of Parallel Transmission
(Master thesis, 2023)Dette studiet undersøker radiofrekvens (RF)-indusert oppvarming av ulike implantater i et gelhodefantom ved bruken av 7T magnetresonanstomografi (MRI). Utviklingen mot høyere statisk magnetfeltstyrker i MRI har ført til ... -
Assessing the value of seismic monitoring of CO2 storage using simulations and statistical analysis
(Peer reviewed; Journal article, 2021)Successful storage of CO2 in underground aquifers requires robust monitoring schemes for detecting potential leakage. To aid in this challenge we propose to use statistical approaches to gauge the value of seismic monitoring ... -
