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 ... -
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 ... -
