Edge Diffraction Implementation by Semi-Transparent Surfaces in Geometrical Room Acoustics
(Master thesis, 2011)This report presents a potential method to efficiently implement edge diffraction from a noise barrier into geometrical room acoustic softwares. The modelling is based on semi-transparent surfaces, and the classic digital ... -
EEG-based Brain Computer Interface for Controlling a Drone - using machine learning, optimized for a battery powered device
(Master thesis, 2018)Brain Computer Interfaces enable the use of brain waves to control computer-based external devices. It can, however, be difficult to trigger a specific brain wave, and it might not be repetitive enough to be used in such ... -
Effect of (111)-oriented strain on the structure and magnetic properties of La2/3Sr1/3MnO3 thin films
(Journal article; Peer reviewed, 2018)Using strain, i.e. subtle changes in lattice constant in a thin film induced by the underlying substrate, opens up intriguing new ways to control material properties. We present a study of the effects of strain on structural ... -
Effect of power ultrasound and Fenton reagents on the biomethane potential from steam-exploded birchwood
(Journal article; Peer reviewed, 2019)The global demand for non-fossil energy sources is increasing rapidly. As a result, biogas presents a suitable alternative; however, first generation biofuels (e.g., sugar cane) potentially impact food crops globally. ... -
Effect of sensor location on continuous intraperitoneal glucose sensing in an animal model
(Journal article; Peer reviewed, 2018)In diabetes research, the development of the artificial pancreas has been a major topic since continuous glucose monitoring became available in the early 2000’s. A prerequisite for an artificial pancreas is fast and reliable ... -
Effect of surface roughness, chemical composition, and native oxide crystallinity on the orientation of self-assembled GaN nanowires on Ti foils
(Journal article; Peer reviewed, 2017)We report on plasma-assisted molecular beam epitaxial growth of almost randomly oriented, uniformly tilted, and vertically aligned self-assembled GaN nanowires (NWs), respectively, on different types of polycrystalline Ti ... -
Effective Channel Hardening in an Indoor Multiband Scenario
(Journal article; Peer reviewed, 2019)We evaluate channel hardening for a large scale antenna system by means of indoor channel measurements over four frequency bands, 1.472 GHz, 2.6 GHz, 3.82 GHz and 4.16 GHz. NTNU’s Reconfgurable Radio Network Platform has ... -
Effects of field annealing on MnN/CoFeB exchange bias systems
(Peer reviewed; Journal article, 2019)We report the effects of nitrogen diffusion on exchange bias in MnN/CoFeB heterostructures as a function of MnN thickness and field-annealing temperature. We find that competing effects occur in which high-temperature ... -
Effects of lattice geometry on the dynamic properties of dipolar-coupled magnetic nanodisk arrays
(Journal article; Peer reviewed, 2019)We have studied the impact of lattice geometry on the dynamic properties of close-spaced arrays of circular nanomagnets, also known as magnonic crystals. To this end, we prepared 2D nanomagnet arrays with both square and ... -
Effects of substrate annealing on the gold-catalyzed growth of ZnO nanostructures
(Journal article; Peer reviewed, 2011)The effects of thermal substrate pretreatment on the growth of Au-catalyzed ZnO nanostructures by pulsed laser deposition are investigated. C-plane sapphire substrates are annealed prior to deposition of a thin Au layer. ... -
Effects of water column variations on sound propagation and underwater acoustic communications
(Journal article; Peer reviewed, 2019)Underwater sound propagation is very sensitive to geometric and environmental variations. The geometric variations are the motion of the source and/or receiver, while the environmental variations are due to surface motion ... -
Effektoptimalisering av trådløse radiomottakere
(Master thesis, 2010)Effektoptimalisering av mottakerarkitekturer er en kompleks oppgave. Et konstruksjonsvalg vil typisk virke inn forskjellig på forskjellige mål for ytelsen i en arkitektur. Det er derfor nyttig for en konstruktør å kunne ... -
