Laser structuring, stress modification and Bragg grating inscription in silicon-core glass fibers
(Journal article; Peer reviewed, 2017)Semiconductor core fibers have numerous potential applications in optoelectronics and photonics, and the key to realizing these opportunities is controlled processing of the material. We present results on laser treatments ... -
Laser-induced spatial composition gradients in SiGe core fiber
(Doctoral theses at NTNU;2020:219, Doctoral thesis, 2020)An important contributor to global warming is greenhouse gas emission caused by burning fuels such as oil and coal. To preserve the environment for the whole world and to simultaneously meet growing global energy demand, ... -
Lattice rotations in precipitate free zones in an Al-Mg-Si alloy
(Journal article; Peer reviewed, 2018)Scanning precession electron diffraction and automated crystal orientation mapping in a transmission electron microscope (TEM) have been applied to quantitatively study the crystal orientation of precipitate free zones ... -
Leakage and dephasing in 28Si-based exchange-only spin qubits
(Journal article; Peer reviewed, 2018)Exchange-only spin qubits hosted in 28Si-based triple quantum dots do not suffer from decoherence caused by randomly fluctuating nuclear-spin ensembles and can be relatively robust against electrical noise when operated ... -
Learners’ Critical Thinking About Learning Mathematics
(Journal article; Peer reviewed, 2021)Developing critical thinking practices among young learners through mathematics education is a topic of attention for mathematics education research community. Learners’ critical thinking concerning cognitive and social ... -
Learning radiation oncology in Europe: Results of the ESTRO multidisciplinary survey
(Journal article; Peer reviewed, 2018)Introduction Radiotherapy education can be very different across Europe, despite the publication of the ESTRO core curricula in 2011. The purpose of the current study is to map the different RO European education systems, ... -
Learning to learn, bolt-on, or integrated? Analysis of student feedback from a pilot with learning to learn integrated into first-year engineering mathematics
(Chapter, 2022)Learning to learn is one of the generic skills that are important to becoming an engineer. One outcome of the education is to be prepared for a role as an engineer with lifelong learning. In this paper, I convey experiences ... -
Legendre-Fenchel transforms capture layering transitions in porous media
(Peer reviewed; Journal article, 2022)We have investigated the state of a nanoconfined fluid in a slit pore in the canonical and isobaric ensembles. The systems were simulated with molecular dynamics simulations. The fluid has a transition to a close-packed ... -
A Legendre–Fenchel Transform for Molecular Stretching Energies
(Peer reviewed; Journal article, 2020)Single-molecular polymers can be used to analyze to what extent thermodynamics applies when the size of the system is drastically reduced. We have recently verified using molecular-dynamics simulations that isometric and ... -
Lévy Processes and Path Integral Methods with Applications in the Energy Markets
(Master thesis, 2011)The objective of this thesis was to explore methods for valuation of derivatives in energy markets. One aim was to determine whether the Normal inverse Gaussian distributions would be better suited for modelling energy ... -
Light Emission of Streamers in Dielectric Liquids
(Master thesis, 2017)Liquid insulation is widely used in various high voltage equipments crucial to a modern electrical grid. It is thus important to understand the behaviour and limits of performance for such liquids. In these experiments, ... -
Light trapping in horizontally aligned silicon microwire solar cells
(Journal article; Peer reviewed, 2015)In this study, we demonstrate a solar cell design based on horizontally aligned microwires fabricated from 99.98% pure silicon via the molten core fiber drawing method. A similar structure consisting of 50 μm diameter close ... -
Limits on primordial black holes
