16. Development of Energy-based Damage and Plasticity Models for Asphalt Concrete Mixtures
Sammanfattning : Characterizing the full range of damage and plastic behaviour of asphalt mixtures under varying strain-rates and stress states is a complex and challenging task. One reason for this is partly due to the strain rate and temperature dependent nature of the material as well as the variation in the properties of the constituent materials that make up the composite asphalt mixture.

17. Congenital and Childhood Myotonic Dystrophy type 1 - the impact on central nervous system, visual and motor function
Sammanfattning : Background and aims: Myotonic dystrophy type 1 (DM1) is an autosomal dominant multisystemic disorder, caused by an expanded CTG repeat on chromosome 19. The disorder can present both in children and adults. LÄS MER
18. Polyethylene/metal oxide nanocomposites for electrical insulation in future HVDC-cables : probing properties from nano to macro
Sammanfattning : Nanocomposites of polyethylene and metal oxide nanoparticles have shown to be a feasible approachto the next generation of insulation in high voltage direct current cables. In order to reach an operationvoltage of 1 MV new insulation materials with reduced conductivity and increased breakdown strengthas compared to modern low-density polyethylene (LDPE) is needed.

19. Urodynamic modelling and measurement techniques for assessment of urethral function during micturition
Sammanfattning : According to Griffiths' theory of flow through elastic tubes the urinary flow is controlled by an elastic constriction. The mechanical properties of this flow-controlling zone are described by the intrinsic urethral pressure as a function of cross-sectional area given by the pressure/area relation p(A)=pmo + KnAn, where pmo is the minimal urethral opening pressure, A the cross-sectional area and Kn and n are parameters describing the distensibility of this zone.

20. In conversation with simulation: The application of numerical simulation to the design of structural nodal connections
Sammanfattning : The thesis explores methods for integration of structural analysis, design and production in a digital design environment. The somewhat ambiguous title implies the ambition to make such integration in relation to the explorative phase of the design process which is described by Donald Schön as having a conversational character.
