   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

3. 7. Control of HCCI by aid of Variable Valve Timings with Specialization in Usage of a Non-Linear Quasi-Static Compensation

   Författare :Fredrik Agrell; Hans-Erik Ångström; Wai K. Cheng; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCCI; Homogeneous; Charge Compression Ignition; Engine Control; Variable Valve Timings; Other technology; Övriga teknikvetenskaper;

   Sammanfattning : This doctoral thesis is about controlling the combustion timing of the combustion concept Homogeneous Charge Compression Ignition, HCCI, by means of variable valve timings. The HCCI research usually is regarded to have started in Japan during the later part of the 1970´s. The world of HCCI has since grown and HCCI is of today researched worldwide. LÄS MER

4. 8. Some applications of representation theory in homogeneous dynamics and automorphic functions

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; automorphic functions; effective equidistribution; Eisenstein series; homogeneous dynamics; horospheres; lattices; Lie groups; representation theory; Mathematics; Matematik;

   Sammanfattning : This thesis consists of an introduction and five papers in the general area of dynamics and functions on homogeneous spaces. A common feature is that representation theory plays a key role in all articles. LÄS MER

5. 9. Complex disease genetics : Utilising targeted sequencing and homogeneous ancestry

   Författare :Argyri Mathioudaki; Kerstin Lindblad-Toh; Panagiotis Deloukas; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ankylosing spondylitis; breast cancer; targeted sequencing; Sweden; genetics; population stratification.; Molekylär genetik; Molecular Genetics;

   Sammanfattning : The complex disease investigations presented in this thesis aimed to provide new information regarding underlying genetics by using targeted sequencing and ethnically homogeneous cohorts. This work moved past current methodologies and addressed data stratification issues, that might have been hindering new findings.
