Solitary waves for dispersive equations with inhomogeneous nonlinearities
(Master thesis, 2017)We prove existence of solitary-wave solutions to a class of pseudodifferential evolution equations with inhomogeneous nonlinearities in one spacial dimension, i.e. we prove existence of solutions of the form u(x-ct), where ... -
Solitary waves for weakly dispersive equations with inhomogeneous nonlinearities
(Peer reviewed; Journal article, 2020) -
Solitary waves in dispersive evolution equations of Whitham type with nonlinearities of mild regularity
(Journal article; Peer reviewed, 2020)We show existence of small solitary and periodic traveling-wave solutions in Sobolev spaces Hs, s>0, to a class of nonlinear, dispersive evolution equations of the formut+(Lu+n(u))x=0,where the dispersion ... -
Solitary waves in equations with fully mixed nonlocal and nonlinear terms
(Master thesis, 2022)Vi studerer eksistens av solitære bølger i to familier av pseudodifferensialligninger med ikkelokale ikkelineariteter. Ikkelineariteten er enten kubisk: $\partial_{t}u + \partial_{x}(Lu - uNu^{2})=0$ eller kvadratisk: ... -
Soliton absorption spectroscopy in normal-dispersion lasers
(Chapter, 2010)An all-normal-dispersion oscillator with narrowband intracavity absorption acquires spectral features which follow the index of refraction of the absorber, as confirmed by experimental obsevation. Compared to the conventional ... -
Soliton delivery of mid-IR femtosecond pulses with ZBLAN fiber
(Journal article; Peer reviewed, 2012)We demonstrate environmentally protected delivery of highpower femtosecond mid-IR pulses in a single-mode ZBLAN fiber by soliton formation. A 70-fs Cr:ZnS laser at 2.4 µm reaches this regime already at ~2 nJ launched pulse ... -
Solitons of general topological charge over noncommutative tori
(Peer reviewed; Journal article, 2021)We study solitons of general topological charge over noncommutative tori from the perspective of time-frequency analysis. These solitons are associated with vector bundles of higher rank, expressed in terms of vector-valued ... -
Solparker i landbruket - en solskinnshistorie?
(Master thesis, 2022)Solparker er et lite diskutert tema i Norge, men i løpet av det siste tiåret har prisene på solkraft sunket drastisk. Erfaringene fra denne oppgaven viser at det finnes store muligheter i Norge for solparker, men solparker ... -
Solsensor design og testing til Orbit NTNUs CubeSat
(Bachelor thesis, 2021)Bachelor-gruppen har hatt som mål å designe og kalibrere en prototype solsensor med Field of View på 60°. Solsensorer er kommersielt sett veldig kostbare, av denne grunnen ønsker Orbit å designe og produsere disse in-house. ... -
"Solskinn" - Konseptforslag for å motivere pasienter til å møte til time ved DPS
(Bachelor thesis, 2021)Prosjektet har undersøkt hvordan motivere pasienter til å møte til time ved DPS, for å bidra til å redusere pasientfravær. For å løse denne problematikken ble det utført tjenestedesign som designprosess, hvor pasienter med ... -

Solubility and characterization of synthesized 11 Å Al-tobermorite
(Peer reviewed; Journal article, 2022)The structure and solubility of hydrothermally prepared 11 Å Al-tobermorite with Al/(Al + Si) = 0.1 has been studied. NMR and FTIR data indicated the formation of a cross-linked, well crystalline 11 Å Al-tobermorite and ... -
Solubility and Heat of Absorption of CO2 into Diisopropylamine and N,N-Diethylethanolamine Mixed with Organic Solvents
(Journal article; Peer reviewed, 2020)We have evaluated the vapor–liquid equilibrium and heat of absorption of CO2 over water-lean mixtures of the amines diisopropylamine and N,N-diethylethanolamine (DEEA). This extends our previous research on water-lean ... -
Solubility of Carbon and Nitrogenin the Silicon Rich Part of theSi–C–N–B-System

Solubility of Carbon Dioxide, Hydrogen Sulfide, Methane, and Nitrogen in Monoethylene Glycol; Experiments and Molecular Simulation
(Peer reviewed; Journal article, 2020)Knowledge on the solubility of gases, especially carbon dioxide (CO2), in monoethylene glycol (MEG) is relevant for a number of industrial applications such as separation processes and gas hydrate prevention. In this study, ... -
Solubility of Nickel in Mg-Al, Mg-Al-Fe, and Mg-Al-Mn Systems
(Doctoral thesis, 2001)The corrosion properties of magnesium alloys strongly depend on the alloy composition and impurities. Heavy elements like nickel, and iron have low solubility in solid magnesium. The dissolved elements in molten magnesium ... -
Solubility Patterns in Relation to Coating of Mineral Supplements
(Master thesis, 2019)Målet for dette prosjektet var å utvikle et belegg eller en bærer for Bolifor® fosfatsalt som brukes i akvakulturfôr. Bæreren/belegget må være slik at det beskytter fosfatsaltet mot å lekke i vann. Lekking av fosfat er et ... -
Soluble collectin-12 mediates C3-independent docking of properdin that activates the alternative pathway of complement
(Peer reviewed; Journal article, 2020)Properdin stabilizes the alternative C3 convertase (C3bBb), whereas its role as pattern-recognition molecule mediating complement activation is disputed for decades. Previously, we have found that soluble collectin-12 ... -
Soluble IL-1 receptor 2 is associated with left ventricular remodelling in patients with ST-elevation myocardial infarction
(Journal article; Peer reviewed, 2018)Background The inflammatory response following myocardial infarction (MI) is prerequisite for proper healing of infarcted tissue, but can also have detrimental effects on cardiac function. Interleukin (IL)-1α and IL-1β ... -
