1. Hydromechanical simulations of wave energy conversion : Linear aspects
Sammanfattning : Hydrodynamic simulations of buoy movement is crucial when designing a point absorbing wave power plant. The wave energy converter (WEC) that is developed in the Lysekil project by Uppsala University is studied in this thesis. LÄS MER
2. Quantum chemical calculations of non-linear optical absorption
Sammanfattning : This thesis represents a quantum chemical treatise ofvarious types of interactions between radiation and molecularsystems, with special emphasis on the nonlinear opticalprocesses of Multi-Photon Absorption and Excited StateAbsorption. Excitation energies, transition dipole moments,two-photon and three-photon tensor elements have beencalculated from different approaches; density functional theoryandab-initiotheory, employing different orders ofcorrelation treatment with the purpose to provide accuratevalues as well as evaluate the quality of the lower ordermethods.

3. Linear wave energy converter : Study of electromagnetic design
Sammanfattning : The thesis presents results from synchronous linear wave energy converters developed at Uppsala University. A study is done on closed stator slots and a study presenting offshore data focusing on the power absorption from a wave energy converter (WEC). LÄS MER
4. Synthesis and development of compounds for nonlinear absorption of light
Sammanfattning : High-intensity light — for instance that from a laser — can be destructive, not only to the human eye, but also to equipment such as imaging sensors and optical communication devices. Therefore, effective protection against such light is desirable. LÄS MER
5. Inhibition of Calcium and Zinc Absorption by Phytate in Man Methodological Studies and Hydrothermal Processing of Cereals to Improve Absorption
Sammanfattning : A mathematical model based on measurements in a whole-body counter described the retention of calcium in the human body. It was shown that the relative retention of intravenous and orally administered 47Ca in all subjects (n = 10 - 11) were well described by fitting a simple function of time with two free parameters to a few whole-body measurements after day 6, when the unabsorbed calcium had been excreted.
