6. Elastic wave scattering by rough crack in an anisotropic solid
Sammanfattning : .... LÄS MER
7. Modeling of Scattering by Cracks in Anisotropic Solids - Application to Ultrasonic Detection
Sammanfattning : Elastodynamic wave scattering in anisotropic solids with application to ultrasonic nondestructive testing (NDT) is treated and mathematically modeled in this thesis. The scatterers are infinite strip-like cracks and the solids are homogeneous and linearly elastic with negligible damping. LÄS MER
8. Laser Diagnostics in Combustion - Elastic Scattering and Picosecond Laser-Induced Fluorescence
Sammanfattning : Elastic scattering and the Lorenz-Mie (LM) theory in particular is used for the characterization of sub-micron- and micron-sized droplets of organic fuels in sprays and aerosols. Calculations on the Lorenz- Mie theory show that backward-sideward scattered visible radiation can be used for unambiguous detection of ensembles of homogeneous droplets of organic substances with diameters around 1 micrometer (size parameter between 2 and 6).

9. Scattering of elastic waves by an anisotropic sphere with application to polycrystalline materials
Sammanfattning : Scattering of a plane wave by a single spherical obstacle is the archetype of many scattering problems in various branches of physics. Spherical objects can provide a good approximation for many real objects, and the analytic formulation for a single sphere can be used to investigate wave propagation in more complex structures like particulate composites or grainy materials, which may have applications in non-destructive testing, material characterization, medical ultrasound, etc. LÄS MER
10. Neutron-Deuteron Scattering and Three-Body Interactions
Sammanfattning : High-precision differential cross section data of the neutron-deuteron elastic scattering reaction at 95 MeV are presented. The neutron-proton scattering differential cross section was also measured and used as a reference to allow an accurate absolute normalization of the neutron-deuteron data. LÄS MER
