   Abstract : This doctoral thesis provides a comprehensive numerical analysis and exploration of several stochastic partial differential equations (SPDEs). More specifically, this thesis investigates time integrators for SPDEs with white noise dispersion. READ MORE

4. 2. From irrotational flows to turbulent dynamos

   Author : Fabio Del Sordo; Axel Brandenburg; Mordecai-Mark Mac Low; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; astrophysics; magnetic fields; insterstellar medium; MHD; dynamo; turbulence; instability; Astronomy; astronomi;

   Abstract : Many of the celestial bodies we know are found to be magnetized:the Earth, many of the planets so far discovered, the Sun and other stars,the interstellar space, the Milky Way and other galaxies.The reason for that is still to be fully understood, and this work is meant to be a step in that direction.

5. 3. The Buddhist World Emperor's Mission : Millenarian Buddhism in Postcolonial Burma

   Author : Niklas Foxeus; Per-Arne Berglie; Erik af Edholm; Guillaume Rozenberg; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Buddhism; millenarianism; weizzā weikza ; esotericism; supernatural powers; identity; politics; Burma; Theravāda Buddhism; cakkavattin; authority; legitimacy; charisma; History of religion; Religionshistoria; History of Religion; religionshistoria;

   Abstract : In early postcolonial Burma, a number of so-called royal esoteric associations with a millenarian and eschatological orientation, and founded by persons believed to be the world emperor, emerged in response to political turmoil, nation-building projects, modernization, and after-effects of colonialism. These Theravāda Buddhist esoteric congregations, revivalist and innovative at the same time, were indicative of a general crisis of authority and identity. READ MORE

6. 4. Homogenization in Perforated Domains

   Author : Martin Strömqvist; Henrik Shahgholian; Scott Armstrong; KTH; []
   Keywords : Mathematics; Matematik;

   Abstract : Homogenization theory is the study of the asymptotic behaviour of solutionsto partial differential equations where high frequency oscillations occur.In the case of a perforated domain the oscillations are due to variations in thedomain of the equation. READ MORE

7. 5. Charge transport in polymer-based insulating materials for high voltage applications: effect of single- and multi-layered structures

   Author : Tuan Anh Hoang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; charge trapping and de-trapping; polyethylene; surface potential decay; enamel insulation; charge transport; charging current; charge injection; charge mobility; DC conductivity; nanocomposite;

   Abstract : Polymer composites have been widely employed as electrical insulating materials for high voltage components and devices such as power cables, gas-insulated systems, rotating machines, line and post insulators, etc. Such materials are usually made by introducing inorganic oxides (SiO2, TiO2, Al2O3, MgO) into polymeric matrices e.g. READ MORE
