Sammanfattning : Atmospheric icing is a large problem for many structures located in regions with cold climate. Structures as guyed masts and overhead transmission lines and towers are particularly exposed. A 323 meter high guyed TV and radio mast in Arvidsjaur in Northern Sweden was equipped with an extensive data collection system in the winter 1988-89. LÄS MER
2. Development and characterization of damped cubic response functions with application to two-photon absorption
Sammanfattning : Molecular response to electromagnetic fields - static or optical - within a framework of perturbation theory diverges close to resonance with molecular transitionen energies, and need work-around solutions for real-valued response functions. This licentiate thesis deals with nonlinear response, with focus being on cubic polarizaibilities, and outlines the underlying mathematics for exact-state and approximatestate, complex-valued response functions applicable to quantum chemical computation.

Sammanfattning : This thesis is titled ’Derivation and application of response functions for nonlinear absorption and dichroisms’ and was written by Tobias Fahleson at the Division of Theoretical Chemistry & Biology at KTH Royal Institute of Technology in Sweden. It explores and expands upon theoretical means of quantifying a number of nonlinear spectroscopies, including two-photon absorption, resonant inelastic x-ray scattering, Jones birefringence, and magnetic circular dichroism.
