Rockslides have a high socioeconomic and environmental importance in many coun- tries. Norway is particularly susceptible to large rockslides due to its many fjords and steep mountains. One of the most dangerous hazards related to rock slope failures are tsunamis that can lead to large loss of life. It is therefore very important to systemati- cally identify potential unstable rock slopes. In this ...

<p>In recent years, Deep learning (DL) networks have shown considerable improvements and have become a preferred methodology in many different applications. These networks have outperformed other classical techniques, particularly in large data settings. In earth observation from the satellite field, for example, DL algorithms have demonstrated the ability to learn complicated nonlinear relationships ...

The Svyatogor Ridge, located in the Fram strait, is a site hosting a fluid flow system. The Svyatogor Ridge is part of the inside corner high at the Knipovich Ridge-Molloy Transform fault intersection. The Knipovich Ridge is an ultra-slow, melt-poor spreading ridge with approximately 8 mm/yr spreading rate. At this northernmost segment of the Knipovich Ridge, spreading is predominantly accommodated ...

Methane, a high potential greenhouse gas, travels as a fluid and releases as a gas in large quantities from the seafloor. This seepage impacts marine ecosystems and in specific cases, it has potential to reach the atmosphere, and therefore affect the climate. Gas seepage is documented worldwide, but there are still large unknowns regarding seepage dynamics, faulting/fracturing of the sediments and ...

Human-model data are very valuable and important in biomedical research. Ethical and economical constraints limit the access to such data, and consequently these datasets rarely comprise more than a few hundred observations. As measurements are comparatively cheap, the tendency is to measure as many things as possible for the few, valuable participants in a study. With -omics technologies it is cheap ...

The thesis contains new results on the connection between the algebraic properties of certain ideals of a polynomial ring and properties of error-correcting linear codes, matroids and simplicial complexes. We demonstrate that the graded Betti numbers of the facet ideal of a matroid are determined by the Betti numbers of the blocks of the matroid. The extended weight enumerator of coding theory is ...

Solar proton events cause large-scale ionization in the Earth's middle atmosphere leading to chemical changes, changes in the energy budget of the middle atmosphere, and radio wave absorption. The accurate implementation of the spatial impact of solar protons and other particle ionization sources in climate models is necessary to understand the role of energetic particle precipitation in natural ...

The use of statistical shape analysis in medical settings has increased during the last decades. This thesis presents contributions to three major topics of statistical shape analysis with application to medical problems. These topics are: the modeling of the shape by a geometrical model, the study of rotational shape deformations and the comparison of shapes between populations. Paper I presents ...

<p>The analysis of curves can be claimed to be the core of most scientific ventures. In this dissertation, we focus on the statistical aspect of this type of analysis. Here, the curves originate from health and food-related areas and include improvements in blood glucose measurements, classification of moles, measurements of parameters during liver transplants in pigs, and data from the monitoring ...
