Sammanfattning : This PhD thesis consists of a summary and five papers which all deal with asymptotic problems on certain homogeneous spaces.In Paper I we prove asymptotic equidistribution results for pieces of large closed horospheres in cofinite hyperbolic manifolds of arbitrary dimension.

Sammanfattning : This thesis is about the application of lean homogeneous combustion in SI engines using a passive SCR after treatment system. By implementing this concept a decrease in fuel consumption and engine out NOx is expected. The data and results are obtained through engine experiments. LÄS MER
Sammanfattning : To use multiprocessors in hard real-time systems, schedulability analysis is needed to provide formally proven guarantees for the timing behavior of the system. Programming models for parallel applications, such as OpenMP, use pragmas to specify parts of the application as parallel tasks, for example, a function or a body of a loop. LÄS MER
Sammanfattning : Used nuclear fuel contains radiotoxic elements with lifetimes in the range of 100 000 years. Although possibilities for recycling of the fuel exist, a final storage for the ultimate high-level waste will be necessary. LÄS MER
5. A Treatise on the Geometric and Electronic Structure of Clusters Investigated by Synchrotron Radiation Based Electron SpectroscopiesDetta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
Sammanfattning : Clusters are finite ensembles of atoms or molecules with sizes in the nanometer regime (i.e. nanoparticles). This thesis present results on the geometric and electronic structure of homogeneous and heterogeneous combinations of atoms and molecules. LÄS MER
