31. An upgrade of the SCANDAL facility for neutron scattering measurements at 175 MeV
Sammanfattning : The experimental setup SCANDAL, used for measurements of the differential cross section for elastic neutron scattering, has been upgraded with new Na doped CsI scintillating detectors for measurements at 175 MeV. Two experimental campaigns have been carried out, collecting data on three different nuclei: iron, bismuth and silicon. LÄS MER
32. Brownian Relaxation Measurements of Magnetic Nanoparticles: Towards the Development of a Novel Biosensor System
Sammanfattning : Magnetic measurements of the Brownian relaxation time of thermally blocked magnetic nanoparticles dispersed in a solution have been performed in order to determine the hydrodynamic size distribution of the particles. By measuring changes in the hydrodynamic size of the particles, the ammount of analytes attached to the surface of particles can be determined. LÄS MER
33. Contributions to nonlinear mixed-effects modeling
Sammanfattning : The topic of this thesis is nonlinear mixed-effects models. A nonlinear mixed-effects model is a hierarchical regression model used to analyze measurements from several individuals simultaneously, which allows sharing of information between similar individuals. LÄS MER
34. Lidar Techniques for Environmental Monitoring
Sammanfattning : Atoms and molecules absorb and emit light at certain, welldefined wavelengths, and this forms the basis of spectroscopy. The wavelengths are given by the discrete energy levels of the atoms/molecules. LÄS MER
35. Volatility and number measurement of diesel engine exhaust particles
Sammanfattning : Today, emission legislations for engine exhaust particles are mass based. The engines of today are low-emitting with respect to particle mass, with the emissions approaching the detection limit of the current measurement method. This calls for new and improved measurement methods. LÄS MER
