Porous media can be characterized by studying the kinetics of liquid rise within the pore spaces. Although porous media generally have a complex structure, they can be modeled as a single, vertical capillary or as an assembly of such capillaries. The main difficulties lie in separately estimating the effective mean radius of the capillaries and the contact angle between the liquid and the pore. In
Kernel density estimation is an important tool in visualizing posterior densities from Markov chain Monte Carlo output. It is well known that when smooth transition densities exist, the asymptotic properties of the estimator agree with those for independent data. In this paper, we show that because of the rejection step of the Metropolis-Hastings algorithm, this is no longer true and the asymptoti
We use integrability to prove the stability of smooth periodic solutions of the Camassa-Holm equation. In particular, the smooth periodic traveling wave solutions are shown to be orbitally stable.

Computer supported gaming is an accepted methodology for the training of decision makers on several levels in crisis management. Commonly these tools are focused on two levels of training. One of them is training managers and leaders as if they had to do everything themselves, like training a general as a tank driver or a gunner, or a politician taking care of a car fire. The other level is aimed
In this thesis we will study some basic concepts in algebraic topology such as the fundamental group, simplicial complexes and simplicial homology. These are then used together with a method called surgery to prove a complete topological classification of closed surfaces.
In this project, calculations for the total binding energy of all even-even nuclei available from experimental data are performed using the HFBTHO program. An artificial neural network is applied to train the information obtained from the HFBTHO calculations and predict the binding energy for the nuclei. The results show impressive improvements to the HFBTHO program. In recent years, the combinati
Performance improvements are always needed in computer graphics. Better performance frees up computational resources which can be used to increase the level of realism in the rendered images. Despite a very rapid development of graphics hardware, we are still far from the point where photo-realistic rendering can be done in real time. Therefore, better algorithms must be developed in order to adva
This design project addressed the need of a real company (which works with fishing boats) to expand its own audience towards a new market and questioned whether its actual product portfolio can fit and be successful in that new environment. The main intention with this project was to explore forms and shapes, which have been the major focus of the work, even though other several parts have been i
In this thesis, I attempt to categorize variable stars found with the OGLE telescope with the main aim being to find binaries containing white dwarfs. To do this, I combine light curve data from the OGLE telescope with data from the large Gaia EDR3 catalogue and a recently published 3-dimensional extinction map to gather the colour and absolute magnitude of the binary stars. Lastly, I use an artif
Detta examensarbete fokuserar på PLC-programmering av en loggningsfunktion med structured text för HKM-robot. Syftet var att skapa en förbättrad och användarvänlig lösning för loggning av meddelanden på olika nivåer, inklusive trace, debug, info, error och warn för att underlätta övervakning och felsökning av PLC-program för HKM-robot. Genom en systematisk metodik och analys av befintliga loggfunkThis thesis focuses on the PLC programming of a logger function using structured text for the HKM robot. The aim was to create an improved and user-friendly solution for logging messages of various levels, including trace, debug, info, error and warn, to facilitate monitoring and debugging of PLC programs for the HKM robot. Through a systematic methodology and analysis of existing logging function
We have previously identified tagSNPs at 8q24.21 influencing glioma risk. We have sought to fine-map the location of the functional basis of this association using data from four genome-wide association studies, comprising a total of 4147 glioma cases and 7435 controls. To improve marker density across the 700 kb region, we imputed genotypes using 1000 Genomes Project data and high-coverage sequen
A celebrated theorem in operator theory is A. Beurling's description of the invariant subspaces in $H^2$ in terms of inner functions [Acta Math. {\bf81} (1949), 239--255; MR0027954 (10,381e)]. To do the same thing for the Bergman space $L^2_a$ has been deemed virtually impossible by many analysts, in view of the fact that the lattice of invariant subspaces is so large, and that the invariant subsp
In the world we live in today, the presence and claims of crisis abound – from climate change, financial and political crisis to depression, livelihoods and personal security crisis. There is a challenge to studying crisis due to the ways in which crisis as a notion, condition and experience refers to and operates at various societal levels. Further, different kinds of crisis can overlap and inter
This paper presents an integrated cognitive robotics systemfor industrial kitting operations in a modern factory setting.The robot system combines low-level robot control and execution monitoring with automated mission and task planning,and a logistics planner which communicates with the factory’smanufacturing execution system. The system has been implemented and tested on a series of automotive k
