1. Laser-Induced Incandescence for Soot Diagnostics: Theoretical Investigation and Experimental Development
Sammanfattning : Laser-induced incandescence, LII, is a laser-diagnostic technique that can be used to measure the volume fraction and the sizes of soot particles suspended in a gas, such as within a combustion process or in its exhausts. The technique is based on the facts that the time-decay of the radiation from laser-heated soot particles is directly related to the particle size in the probed volume, and that the time-integrated radiation is related to the soot volume fraction.

2. Surrogate Measures of Safety with a Focus on Vulnerable Road Users : An exploration of theory, practice, exposure, and validity
Sammanfattning : Surrogate measures of safety (SMoS) are meant to function as tools to investigate traffic safety. The term surrogate indicates that these measures do not rely on crash data; instead, they focus on identifying safety critical events (or near-crashes) in traffic, which can be used as an alternative to crash records.

3. Structures in High-Dimensional Data: Intrinsic Dimension and Cluster Analysis
Sammanfattning : With today's improved measurement and data storing technologies it has become common to collect data in search for hypotheses instead of for testing hypotheses---to do exploratory data analysis. Finding patterns and structures in data is the main goal. LÄS MER

5. Characterization of Gcn5 histone acetyltransferase in Schizosaccharomyces pombe
Sammanfattning : The organisation of eukaryotic DNA into chromatin provides a natural barrier that prevents full access to the DNA thereby inhibiting events such as transcription, replication and repair. In order for these DNA-related events to occur, the chromatin needs to be modified by chromatin remodelling or, by reversible post-translational modifications. LÄS MER
