1. Models of porous, elastic and rigid materials in moving fluids
Sammanfattning : Tails, fins, scales, and surface coatings are used by organisms for various tasks, including locomotion. Since millions of years of evolution have passed, we expect that the design of surface structures is optimal for the tasks of the organism. These structures serve as an inspiration in this thesis to identify new mechanisms for flow control. LÄS MER
2. Manufacturing and Characterization of Cellulose Nanofibers
Sammanfattning : The usage of wood has been a dominant driving force during the evolution of the human species. It allowed us to cook food, build tools, put roofs over our head and explore the world. The fibers making up the tree has been the most important way to store and transmit knowledge in the form of paper for centuries. LÄS MER
3. Homogenization of some problems in hydrodynamic lubrication involving rough boundaries
Sammanfattning : This thesis is devoted to the study of some homogenization problems with applications in lubrication theory. It consists of an introduction, five research papers (I–V) and a complementary appendix.Homogenization is a mathematical theory for studying differential equations with rapidly oscillating coefficients.

4. Modelling of fracture toughness using peridynamics : A Study of J-integral, essential work and homogenisation
Sammanfattning : Fracture toughness is one of the most important properties of a material. Being able toaccurately estimate the energy that goes into forming new crack surfaces is essential for the development of new materials, quality assurance, structural monitoring and failure analysis. LÄS MER
5. Direkt demokratins svårigheter: En studie av den tyska Graswurzelrörelsen och dess organisation Graswurzelrevolution, Föderation Gewaltfreier Aktionsgruppen (FöGA) : [The Difficulties of Direct Democracy: A Study of the German Graswurzel Movement and its Organisation Graswurzelrevolution Föderation Gewaltfreier Aktionsgruppen (FöGA)]
Sammanfattning : Syftet med denna uppsats är att studera svårigheterna i att tillämpa direktdemokratiska strukturer i en organisation. Klarar fallexemplet, den tyska anarkistiska och pacifistiska organisationen Graswurzelrevolution, av att tillämpa sina radikaldemokratiska principer under tiden 1972 till 1996? Jag har genomfört studien med hjälp av litteraturstudier, deltagande observation, arkivstudier och intervjuer och speciellt intresserat mig för organisationens formella respektive informella makt- och konflikthantering.
