Circulation and Ocean Driven Glacial Melting in a Greenland Fjord
(Master thesis, 2017-11-20)The Nioghalvfjerdsbræ (79NG) is a floating ice tongue on Northeast Greenland draining a large part of the Greenland Ice Sheet. New hydrographic observations show that Atlantic Water (AW, T > 0 °C, S > 34.3 psu) recirculates ... -
Climate forcing of summer carbon drawdown in the subpolar North Atlantic
(Master thesis, 2015-08-28)This thesis present a 9-year long time series of surface seawater fCO2 data obtained aboard the MV Nuka Arctica. The Nuka Arctica provide full seasonal fCO2 measurements which give a good picture of the fCO2 variability ... -
Climatic mean and interannual variation of northern Barents Sea water mass distribution and circulation. A combined study of ROMS, current and hydrography observations
(Master thesis, 2008-06-02)Evaluating current measurements, hydrography observations and model (ROMS) results of the northern Barents Sea, water mass distribution and circulation is investigated. Water mass exchange with the Arctic Ocean is linked ... -
Climatology of polar lows impacting Norway
(Master thesis, 2016-06-01)Polar lows (PLs), mesoscale cyclones in high latitudes, impacting Norway are studied in this thesis. A climatology of PLs in the Nordic seas for the period 1979-2015 is made, by applying a cyclone detection and tracking ... -
Cold nuclear fusion theories. Exploration of exotic hydrogen states
(Master thesis, 2018-05-10)Nuclear fusion technologies hold the potential to revolutionize the way we produce energy on earth. It is an opportunity to lift our current dependency on external factors such as weather and fossil reserves while producing ... -
Constraining the exchange through the strait of Bab el Mandab
(Master thesis, 2012-10-01)The strait of Bab el Mandab connects the Red Sea with the Indian ocean via the Gulf of Aden. The mean circulation at the strait is a three-layered exchange. The circulation in the Red Sea is understood to be driven by the ... -
Constructive and experimental examination of reliability and robustness in dynamically stressed bolted joints
(Master thesis, 2018-12)Loosening and failure of bolts and nuts is, and has historically always been, a challenge for industries all over the world. This thesis examines the bolted connections of a local plough manufacturer (hereafter referred ... -
Cool Roofs in Smart Cities: Implications for Urban Heat Island Mitigation and Building Energy Efficiency in Different Climate Zones
(Master thesis, 2018-10-05)As climate change contributes to elevate urban temperatures, undesirable consequences like increased energy consumption, reduced air and water quality and elevated levels of thermal stress for the population continue to ... -
Deep weakly-stratified layers in the Greenland Sea
(Master thesis, 2021-12-06)Deep weakly-stratified layers in the Greenland Sea constitute a mode of convection poorly understood. The Greenland Sea is where the densest portion of the overflow waters on either side of Iceland are formed through ... -
Dense water formation in the Greenland Sea between 1999 and 2009
(Master thesis, 2019-08-22)A 10-year continuous hydrographic data record from moored profilers located in the central Greenland Sea between 1999 and 2009 were used to examine the mixed-layer depth evolution through winter as well as interannual ... -
Design of rectifier system for electric ferries
(Master thesis, 2018-06-16)This study investigates the requirements and technologies to provide power from shore to ship when the electric ferry is at quay. Different rectifier systems will be evaluated in terms of requirements given by the utility ... -
Development and Comparison of Compressor Models for Heat Pump Applications in TRNSYS
(Master thesis, 2018-06-22)Heat pump systems may serve as a replacement for many heating systems using fossil fuels for heating purposes. Heat pumps are widely used in Norway where electric energy is abundant and inexpensive. Research and development ... -
The development and evaluation of an idealized ocean model for the Bergen Dynamic Model
(Master thesis, 2013-11-20)Three idealized ocean model versions are developed for the Bergen Dynamic Model (Bedymo). All three model versions fall into the category of slab ocean models. One version is more or less a standard slab ocean model, while ... -
Dispersion and abundance of salmon lice (Lepeophtheirus salmonis) in a Norwegian fjord system
(Master thesis, 2011-11-20)Based on numerical results of currents from a high resolution fjord model, dispersion of salmon lice (Lepeophtheirus salmonis) in the Hardangerfjord has been modelled. The results show that salmon lice abundance in the ... -
Dissolved Oxygen and Biochemical Oxygen Demand in the waters close to the Quelimane sewage discharge
(Master thesis, 2010-06-01)The River dos Bons Sinais Estuary is one of the most important estuaries in the central region of the Mozambican coast. It is situated between the confluence of Cuácua and Licuári rivers and the Mozambican Channel in the ... -
Dynamic Modelling of Squirrel Cage Induction Motors for Studying Motor Current Signature Analysis
(Master thesis, 2018-06-16)This study investigates dynamic modelling of induction motors with a variety of different defects and condition monitoring of these. The focus is directed at squirrel cage induction motors(SCIM) which is the most used ... -
Dynamics and Predictability of the Extreme Extratropical Cyclone Nina
