6. Dynamics of high-angle grain boundary YBCO Josephson junctions
Sammanfattning : This thesis describes experimental investigations of properties of high-angle YBa2Cu3O7−δ(YBCO)bicrystal Josephson junctions and SQUIDs fabricated on SrTiO3-substrates. The main focus of theinvestigation has been on the effects of the predominant d-wave symmetry of the superconductingwavefunction in YBCO on transport properties and dynamics. LÄS MER
7. Electromagnetic Modelling for the Estimation of Wood Parameters
Sammanfattning : Spiral grain in trees causes trouble to the wood industry, since boards sawn from trees with large grain angle have severe problems with form stability. Measurements of the grain angle under bark enable the optimisation of the refining process. LÄS MER
8. Sensitivity Analysis and Material Parameter Estimation using Electromagnetic Modelling
Sammanfattning : Estimating parameters is the problem of finding their values from measurements and modelling. Parameters describe properties of a system; material, for instance, are defined by mechanical, electrical, and chemical parameters. Fisher information is an information measure, giving information about how changes in the parameter effect the estimation. LÄS MER
9. Birch Stem and Wood Traits in Genetic and Silviculture Trials in Southern Sweden
Sammanfattning : Swedish tree species of birch (silver: Betula pendula and downy: B. pubescens) are often neglected during forest management activities, resulting in low value logs. This thesis investigated birch stem characteristics and wood properties important for solid wood products, in genetics and management trials in southern Sweden. LÄS MER
10. In-plane mechanical properties of birch plywood and its performance in adhesively bonded connections
Sammanfattning : Birch (Betula spp.) is a hardwood species with a wide natural distribution on the Eurasian continent, especially in northern Europe. LÄS MER
