Density Functional Theory Studies of Precipitate Interfaces in Aluminium Alloys, with Focus on Theta'-Al2Cu
(Master thesis, 2016)The atomic structure of bulk crystal of aluminium and the precipitate phase $\theta^\prime$ connected to age-hardening of Al-Cu alloys have been studied using Density Functional Theory (DFT). The lattice constant of ... -
Density of States and Critical Temperature in Superconductor/Ferromagnet Structures with Spin-Orbit Coupling
(Master thesis, 2015)We present both an analytical discussion of the weak proximity regime, and a full numerical investigation of the strong proximity regime. The results show that the spin-orbit coupling leaves a clear trace in the density ... -
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 ... -
Design and Analysis of Optical Fiber Probes for Glucose Sensing in the Peritoneal Cavity
(Master thesis, 2016)This thesis is focused on the design and analysis of optical fiber probes for glucose sensing in the peritoneal cavity. The probes are to be used as absorption cells for near-infrared absorption spectroscopy of peritoneal ... -
Design and Construction of Mueller Matrix Scatterometer for Use in Metasurface Characterisation
(Master thesis, 2022)Konstruksjonen av et komplett Mueller matrise scatterometer er presentert i denne avhandlingen. Til dette formålet har en supercontinuum laserkilde i kombinasjon med akusto-optiske filetere blitt brukt som en strålingskilde. ... -
Design and fabrication of (Cr + N) co-doped TiO2 films with a continuous compositional spread
(Doctoral theses at NTNU;2023:228, Doctoral thesis, 2023)Intermediate band solar cells (IBSCs) have a theoretically conversion efficiency that is approximately 50 % higher than for the solar cell technologies dominating today. IBSCs are based on a new type of materials, where ... -
Design knowledge and teacher-student interactions in an inventive construction task
(Journal article; Peer reviewed, 2013)The teacher plays an important role in the Technology and Design (T&D) classroom in terms of guiding students in their design process. By using concepts developed within engineering philosophy along with a framework for ... -
Design of a 5-axis Manipulator for Use in Angle-Resolved Photoemission Spectroscopy
(Master thesis, 2016)The design of a 5-axis manipulator for use in Angle-Resolved Photoemission Spectroscopy (ARPES) is presented along with an outline of the specific challenges it was designed to adress. The theory and nomenclature of X-ray ... -
Design of an End-Pumped Laser Source for Generation of High-Energy Nanosecond Pulses at 1.6 µm Wavelength
(Master thesis, 2015)A numerical model for simulating a pulsed laser has been implemented. The modelled laser can generate pulses with a duration of a few nanoseconds and a tunable wavelength. The laser consists of a diode-pumped neodymium-LiYF4 ... -
Design of multi-luminescent silica-based nanoparticles for the detection of liquid organic compounds
(Journal article; Peer reviewed, 2024)Tracer testing in reservoir formations is utilised to determine residual oil saturation as part of optimum hydrocarbon production. Here, we present a novel detection method of liquid organic compounds by monodisperse SiO2 ... -
Design, test and implementation of a UV 355 nm LIDAR depolarization channel to characterize particles in the atmosphere above ALOMAR
(Master thesis, 2023)Det har lenge vært kjent at aerosoler gir en netto avkjølede effekt i klimabalansen, likevel er det individuelle strålingspådrivet til noen aerosoler fremdeles ukjent. En større forståelse for disse atmosfæriske partiklene ... -
