21. Efficient Simulation of Wave Phenomena
Sammanfattning : Wave phenomena appear in many fields of science such as acoustics, geophysics, and quantum mechanics. They can often be described by partial differential equations (PDEs). As PDEs typically are too difficult to solve by hand, the only option is to compute approximate solutions by implementing numerical methods on computers. LÄS MER
22. Evolution and taxonomy of Cambrian arthropods from Greenland and Sweden
Sammanfattning : Arthropods have a rich fossil record spanning the Phanerozoic. Biomineralized forms such as the extinct trilobites are particularly common and are proven index fossils for biostratigraphy. Forms with an unmineralized cuticle are more rare, preserved only in so called konservat lagerstätten. LÄS MER
23. Direct Numerical Simulation of Turbulence on Heterogenous Computer Systems : Architectures, Algorithms, and Applications
Sammanfattning : Direct numerical simulations (DNS) of turbulence have a virtually unbounded need for computing power. To carry out these simulations, software, computer architectures, and algorithms must operate as efficiently as possible to amortize the large computational cost. LÄS MER
24. Tunable superconducting transmissionline resonator for qubit coupling
Sammanfattning : In this licentiate thesis design, fabrication, and measurements of tunable superconducting microwave transmission line resonators are described. The resonators are of quarter wavelength type were the tuning is achieved by changing one of the boundary conditions of the resonator through a tunable impedance. LÄS MER
25. On the Analysis of Horns, Reflectors, and Periodic Structures
Sammanfattning : The design and manufacturing of a dual-frequency horn is presented. The dual-depth corrugated horn is fed by a circular and a coaxial waveguide, in the upper and lower frequency band, respectively. The reason for choosing a waveguide-only feeding network is discussed. LÄS MER
