MYOCARDIAL STRAIN MEASUREMENTS WITH MRI USING FEATURE TRACKING
(Master thesis, 2016)Myocardial strain is increasingly used in determination of myocardial function in the medical field due to its ability to detect cardiac diseases in the early stages, its ability to quantify regional myocardial function ... -
A bridge between statistical learning and agent based modelling in stock market predictions
(Master thesis, 2016)The research related to agent based modelling and statistical learning has increased in the recent years, as alternatives to main stream econometrics. This project combines the three for constructing and evaluating a ... -
Describing synchronization and topological excitations in arrays of magnetic spin torque oscillators through the Kuramoto model
(Journal article; Peer reviewed, 2016)The collective dynamics in populations of magnetic spin torque oscillators (STO) is an intensely studied topic in modern magnetism. Here, we show that arrays of STO coupled via dipolar fields can be modeled using a variant ... -
Accurately measured precipitate–matrix misfit in an Al–Mg–Si alloy by electron microscopy
(Journal article, 2016)The age-hardenable Al–Mg–Si alloy system is strengthened by needle-shaped coherent β″ phase precipitates. Using distortion-corrected high-resolution scanning transmission electron microscopy images, we measure the considerable ... -
Behaviour of the S1 and S2 Components of the Semidiurnal Tide in the MLT
(Master thesis, 2016)9 years (2000-2008) of wind data from a longitudinal chain of up to 10 Super Dual Auroral Radar Network (SuperDARN) radars spanning over 184 degrees in longitude and ranging in latitude from 51.4 - 65.7 degrees N is used ... -
Nanoparticle uptake by brain endothelial cells and focused ultrasound-mediated transport across the blood-brain barrier
(Doctoral theses at NTNU;2017:3, Doctoral thesis, 2016)More and more people in the world suffer from various brain diseases such as Parkinson’s disease, Alzheimer’s disease and brain cancer. One of the reasons it is so difficult to treat them is the blood-brain barrier (BBB) ... -
Feasibility of Using Phototherapy with Sunlight for Treatment of Neonatal Jaundice in Low-Income Countries
(Master thesis, 2016)This thesis aimed to investigate the feasibility of using sunlight exposure as treatment for neonatal jaundice in low-income countries. The investigation answered four questions: 1. Is it feasible to treat infants with ... -
Effect of task-correlated physiological fluctuations and motion in 2D and 3D echo-planar imaging in a higher cognitive level fMRI paradigm
(Journal article; Peer reviewed, 2016)Purpose: To compare 2D and 3D echo-planar imaging (EPI) in a higher cognitive level fMRI paradigm. In particular, to study the link between the presence of task-correlated physiological fluctuations and motion and the fMRI ... -
Electric field control of magnon-induced magnetization dynamics in multiferroics
(Journal article; Peer reviewed, 2016)We consider theoretically the effect of an inhomogeneous magnetoelectric coupling on the magnon-induced dynamics of a ferromagnet. The magnon-mediated magnetoelectric torque affects both the homogeneous magnetization and ... -
Quantitative atomic force microscopy and light microscopy of hydrogels and cells
(Doctoral theses at NTNU;2016:343, Doctoral thesis, 2016)Quantitative biology is an interdisciplinary subject that combines biology, mathematics and physics. Intimate collaboration on a global scale between these disciplines results in a wide variety of tools and innovation in ... -
Transporterer atmosfæriske bølger polarlysprodusert NO ned til den midtre atmosfæren
(Master thesis, 2016)Hensikten med denne studien var å undersøke potensielle mekanismer bak observerte nivåer av NO-gass i mesosfæren på høyder mellom 60 og 80 kilometer. Tre hypoteser ble formulert og undersøkt i denne sammenheng. Lokal ... -
Controlled microfluidic emulsification of oil in a clay nanofluid: Role of salt for Pickering stabilization
(Journal article; Peer reviewed, 2016)Research on emulsions is driven by their widespread use in different industries, such as food, cosmetic, pharmaceutical and oil recovery. Emulsions are stabilized by suitable surfactants, polymers, solid particles or a ... -
Feasibility study of the permeability and uptake of mesoporous silica nanoparticles across the blood-brain barrier
(Journal article; Peer reviewed, 2016)Drug delivery into the brain is impeded by the blood-brain-barrier (BBB) that filters out the vast majority of drugs after systemic administration. In this work, we assessed the transport, uptake and cytotoxicity of promising ... -
Monte-Carlo studies of multi-component Ginzburg-Landau theories with competing interactions
(Doctoral thesis at NTNU;2016:214, Doctoral thesis, 2016)This thesis presents four research papers in the field of condensed-matter theory. Three of the papers make use of large-scale Monte-Carlo simulations to explore various aspects of Bose-Einstein condensates with multiple ... -
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 ... -
Robot Control in Image-Guided Intervention
(Master thesis, 2016)Introducing autonomous robot systems in clinical medicine is deemed extremely challenging due to the complex scene involved and variations between patients. The majority of commercialized systems are controlled directly ... -
