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 ... -
Assessment of Articular Cartilage by Second Harmonic Microscopy: Challenges and Opportunities
(Journal article; Peer reviewed, 2019)Second harmonic microscopy (SHM) has emerged as a powerful non-destructive optical imaging modality that has high potential to perform the advanced structural characterization of intact articular cartilage. This article ... -
Assessment of Gestational Age using Optical Methods
(Master thesis, 2020)Kvart år blir om lag 15 millionar nyfødde fødd for tidleg, og ein stor del av desse tilfella skjer i låg- og mellominntektsland. Komplikasjonar knytt til prematur fødsel er den viktigaste årsaka til barnedødelegheit globalt. ... -
Assessment of sensitivity, degradation and treatment response in two breast cancer xenograft models using HR MAS MRS
(Master thesis, 2011)Breast cancer is the most frequently form of cancer in women and new methods fordiagnostics and monitoring of treatment are desired. High resolution magic angle spin-ning magnetic resonance spectroscopy (HR MAS MRS) has ... -
Asymmetric ferromagnetic resonance, universal Walker breakdown, and counterflow domain wall motion in the presence of multiple spin-orbit torques
(Journal article; Peer reviewed, 2013)Measurement of the maximum blood flow velocity is the primary means for determining the degree of carotid stenosis using ultrasound. The current standard for estimating the maximum velocity is Pulsed Wave (PW) Doppler with ... -
Asymmetriske Energivariasjoner i Turbulens: Invers statistikk metode for beskrivelse av asymmetrisk energivariasjon
(Master thesis, 2011)Energivariasjon i fullt utviklet turbulens er studert. I en tidsserie for tur- bulens energi er det oppdaget en asymmetri mellom positive og negative energiendringer. Invers statistikk metode gir en mulighet til å studere ... -
Atmospheric Correction over Coastal Waters Based on Machine Learning Models
(Master thesis, 2020)Atmospheric correction (AC) is often the first step in ocean-color remote sensing algorithms for satellites and would ideally remove atmospheric and ocean surface radiances to produce water-specific properties like the ... -
Atmospheric dispersion management in mid-IR mode-locked oscillators
(Peer reviewed; Journal article, 2023)The atmospheric dispersion in the mid-infrared transparency windows presents an important albeit often neglected factor when developing ultrashort-pulsed lasers. We show that it can amount to hundreds of fs2 in 2–3 µm ... -
Atmospheric ozone above Troll station, Antarctica observed by a ground based microwave radiometer
(Journal article; Peer reviewed, 2014)This paper describes the stratospheric and mesospheric ozone profiles retrieved from spectral measurements of the 249.96 GHz O3 line, using the British Antarctic Survey's ground-based Microwave Radiometer at Troll (BAS-MRT), ... -
Atmospheric Tides in the Mesosphere and Lower Thermosphere: Meteor Radar Observations and Mechanistic Tidal Model Simulations
(Doctoral theses at NTNU;2022:131, Doctoral thesis, 2022)Atmospheric tides are global-scale waves whose periods are an integer fraction of a solar or lunar day. While the tides are primarily excited in the lower atmosphere, their amplitudes can become very large at high altitudes. ... -
Atmospheric tomography using the Nordic Meteor Radar Cluster and Chilean Observation Network de Meteor Radars: Network details and 3D-Var retrieval
(Peer reviewed; Journal article, 2021)Ground-based remote sensing of atmospheric parameters is often limited to single station observations by vertical profiles at a certain geographic location. This is a limiting factor for investigating gravity wave dynamics ... -
Atomap - Automated Analysis of Atomic Resolution STEM Images
(Journal article, 2017)Atomic resolution scanning transmission electron microscopy (STEM) data contain a large amount of information about the structure of a crystalline material. Often, this information is hard to extract, due to the large ... -
Atomap: a new software tool for the automated analysis of atomic resolution images using two-dimensional Gaussian fitting
(Journal article; Peer reviewed, 2017)Scanning transmission electron microscopy (STEM) data with atomic resolution can contain a large amount of information about the structure of a crystalline material. Often, this information is hard to extract, due to the ... -
Atomic force microscopy and variable angle spectroscopic ellipsometry of oxidising GaAs substrates for intermediate band solar cells
(Master thesis, 2018)The AFM images of the substrate sample revealed pits all over the sample surface that were tens of nanometers deep. The geometry of the pits on the surface seemed to be affected by the geometry of the AFM probe tip, ... -
Atomic force microscopy measurements for the surface and the interaction characterization to optimize the surface patterning for bacterial micro arrays
(Master thesis, 2013)This Master project was done in the Department of Physics at NTNU in the spring2013. The project focus on the optimization of micro patterning techniques to producemicro arrays for single bacterial cell studies. The micro ... -
