Sphero NAV - Robotic Navigation and Control Platform
(Master thesis; Mastergradsoppgave, 2014-06-01)
This thesis presents Sphero NAV, a camera based navigation and control platform for the robotic ball Orbotix Sphero. Sphero NAV is a Python library that serves as a base for developing new Sphero applications. The library allows for communication and control of one or multiple Sphero devices using Sphero’s rich API and functionality. Sphero NAV implements a tracker system that uses image based ...
Super-Resolution Imaging of Sub-Mitochondrial Structures using Structured Illumination Microscopy
(Master thesis; Mastergradsoppgave, 2016-05-15)
Modern science is based on observation, and its advances are limited by what is possible to observe. For centuries optical microscopy was limited by the diffraction of light, making structures closer together than half the wavelength of light unresolvable. In recent years, the new field of optical nanoscopy has emerged, enabling diffraction-limited structures to be resolved. As opposed to ...
Bruk av teknologiske verktøy og problemløsning i arbeid med forståelse av funksjonsbegrepet
(Master thesis; Mastergradsoppgave, 2016-05-31)
Oppgaven beskriver et undervisningsopplegg som ble gjort i emnet funksjoner på en ungdomsskole. Undersøkelsen ble gjennomført med hjelp fra seks 10.klasseelever. Studien bestod av to intervjuer og et undervisningseksperiment. Det ene intervjuet ble gjennomført før undervisningen for å etablere hvordan kunnskapsnivået til elevene var og det andre ble gjennomført i etterkant. Undervisningen ...
Reconstructions of paleoceanography and ice retreat based on benthic foraminifera, stable isotopes and sedimentological investigations from the northwestern Barents Sea south of Nordaustlandet, Svalbard
(Master thesis; Mastergradsoppgave, 2016-07-12)
One gracity core NP05–11–49GC was retrieved from a 320 m water depth in the central part of Erik Eriksen Strait, south of Nordaustlandet, northwestern Barents Sea. The core was investigated for benthic foraminiferal distribution patterns, stable isotopes and sedimentological parameters in order to reconstruct the Late Weichselian deglaciation and Holocene paleoenvironment and paleoceanography of the ...
Paleoceanographic development in Leirdjupet, during the last deglaciation
(Master thesis; Mastergradsoppgave, 2016-08-23)
The focus of this master thesis is to investigate the paleoenvironmental and paleoceanography during the last deglaciation in Leirdjupet, a small submarine trough in the southwestern Barents Sea. The lower half of the piston corer HH15-1303PC has been investigated for the distribution pattern of benthic foraminifera faunas, ice rafted debris (IRD), lithology and oxygen and carbon isotopes covering; ...
Investigation of the ion composition in the topside ionosphere at solar maximum using incoherent scatter technique
(Master thesis; Mastergradsoppgave, 2016-05-15)
The aim of this study was to investigate the altitudinal and diurnal variations of light ion densities in the topside ionosphere during the 23rd and 24th solar maximums. This made it possible to understand the behavior of the ion composition after extended solar minimum and compare how it differs from the preceding solar maximum. The observed variations are compared with estimates of empirical (IRI) ...
A compact portable resonance probe system for in situ measurements of snow conditions
(Master thesis; Mastergradsoppgave, 2018-01-31)
A resonance probe for measuring the dielectric properties of snow in terms of the resonance frequency is described and tested. The dielectric properties of snow are closely related to the density and the water content in snow. Having a probe capable of measuring the dielectric properties is therefore a useful tool for anyone working with quantitative descriptions of snow properties. In situ measurements ...
Insulating the Vacuum. Calculating the Casimir force using the boundary integral method with von Neumann boundary conditions
(Master thesis; Mastergradsoppgave, 2016-08-15)
In 2012, a new method for calculating the Casimir force between compact objects was developed, expressing the force in terms of a boundary integral equation. The case of perfectly conducting objects with Dirichlet boundary conditions in two dimensions was treated by Isak Kilen. The method was later extended to three dimensions by Karl Øyvind Mikalsen. The contribution of this thesis will be to ...
Petrographic investigation of methane-derived authigenic carbonate crusts from Barents Sea and Norwegian Sea
(Master thesis; Mastergradsoppgave, 2016-06-15)
Methane-derived authigenic carbonate crusts from four seepage sites at the Loppa High in the southwestern Barents Sea, and one seepage site at Hola, off Vesterålen in the Norwegian Sea, have been investigated, with the main focus of understanding if and how the tests of benthic and planktonic foraminifera occurring in the crusts could serve as nucleation centers for the precipitated carbonates.
A complex contour based perfectly matched layer applied to a pattern generating model equation.
(Master thesis; Mastergradsoppgave, 2017-02-17)
The observable universe consists of several non equilibrium systems that generate spatiotemporal behaviour in the form of various patterns. As the elementary laws of physics and chemistry are unable to explain the pattern forming behaviour of such systems, scientists have turned to desktop experiments and model equations to gain further insight. The model equations that generate numerical solutions ...
