Baadshaug, Ole (Master thesis; Mastergradsoppgave, 2018-06-29)Moving icebergs represent a major problem for shipping, as well as for oil and gas installations in ice infested waters. To be able to take actions against hazardous icebergs, it is necessary to develop models for prediction of iceberg drift trajectories. Many models have been developed in order to do so, using different approaches. These approaches can be divided into two main categories, dynamic ...
Long-range memory in Earth surface temperatures: spatial scale dependence and land-sea differences Fredriksen, Hege-Beate (Master thesis; Mastergradsoppgave, 2013-05-15)The use of long-range memory models as a description of the noise in Earth surface temperatures has increased the recent years, and as a measure of the persistence for such time series we have the Hurst exponent. It is known that sea surface temperatures are more persistent than land temperatures, and that global temperatures are more persistent than local temperatures. We also know that the persistence ...
Johansen, Thomas A. Haugland (Master thesis; Mastergradsoppgave, 2016-12-08)The key objectives in this thesis are; the study of GPU-accelerated eigenvalue decomposition in an effort to uncover both benefits and pitfalls, and then to investigate and facilitate a future GPU implementation of the symmetric QR algorithm with permutations. With the current trend of having ever larger datasets both in terms of features and observations, we propose that GPU computation can help ...
