11. Inflation and Instabilities of Hyperelastic Membranes
Sammanfattning : The applications of membranes are increasing rapidly in various fields of engineering and science. The geometric, material, force and contact non-linearities complicate their analysis, which increases the demand for computationally efficient methods and interpretation of counter-intuitive behaviours.

12. Mathematical modelling approach to collective decision-making
Sammanfattning : In everyday situations individuals make decisions. For example, a tourist usually chooses a crowded or recommended restaurant to have dinner. Perhaps it is an individual decision, but the observed pattern of decision-making is a collective phenomenon. LÄS MER
13. Plastic instability analysis of plane frames using a co-rotational approach
Sammanfattning : .... LÄS MER
14. Computer-aided Computation of Abelian integrals and Robust Normal Forms
Sammanfattning : This PhD thesis consists of a summary and seven papers, where various applications of auto-validated computations are studied. In the first paper we describe a rigorous method to determine unknown parameters in a system of ordinary differential equations from measured data with known bounds on the noise of the measurements.

15. Rheology of cement grout : Ultrasound based in-line measurement technique and grouting design parameters
Sammanfattning : Grouting is performed in order to decrease the permeability and increase the stiffness of the material, especially soil and rock. For tunnelling and underground constructions, permeation grouting is done where cement based materials are pumped inside drilled boreholes under a constant pressure, higher than the ground water pressure.
