6. Time Domain Boundary Element Methods for Acoustic Scattering
Sammanfattning : In room acoustics, numerical computation of scattering phenomena is an important subject, since it is needed to accurately predict the influence of reflectors, the audience, balconies, etc, on the perceived acoustic quality of auditoria. The large physical volumes of auditoria and the wide frequency content of music and speech, together with the complicated geometries involved however, makes predictions in room acoustics a challenging task from a computational point of view.

7. Energy system perspectives on transport biofuel policies – a modelling analysis
Sammanfattning : Climate concerns and energy security issues have in recent years triggered the interest in biofuels for transport. This has resulted in governmental and intergovernmental targets that, if implemented, will lead to an unprecedented growth in biofuel production. LÄS MER
8. Rytmens estetik, formens kraft
Sammanfattning : We meet rhythm as a concept for composition within all forms of art. In this thesis I discuss visual and spatial rhythms. In my research I have reflected about how one via rhythmisation can build up the feeling of a work’s internal movement. LÄS MER
9. Hydro-mechanical optimization of a wave energy converter
Sammanfattning : Wave energy conversion technology has gained popularity due to its potential to be-come one of the most preferred energy sources. Its high energy density and low car-bon footprint have inspired the development of many wave energy converter (WEC) technologies, few of which have made their way to commercialisation, and many are progressing.

10. Studies of Edge Diffraction and Scattering: Applications to Room Acoustics and Auralization
Sammanfattning : This thesis examines ways of including edge diffraction and surface scattering to improve room acoustics auralization, i.e., the binaural replication of an acoustic environment. The approach combines numerical and psychoacoustical studies to discern what level of computational accuracy is necessary to obtain perceptually adequate replication. LÄS MER
