1. Signal Transduction in Photoreceptor Proteins : Insights From Time-Resolved X-ray Solution Scattering
Sammanfattning : The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals with this ability. LÄS MER
2. Time-domain Reconstruction Methods for Ultrasonic Array Imaging : A Statistical Approach
Sammanfattning : This thesis is concerned with reconstruction techniques for ultrasonic array imaging based on a statistical approach. The reconstruction problem is posed as the estimation of an image consisting of scattering strengths. LÄS MER
3. Multi-Dimensional Quantitative Laser-based Diagnostics - Development and Practial Applications
Sammanfattning : Laser based optical diagnostic methods are routinely used in combustion research. Many of the more common approaches are based on illuminating a cross-section of the sample with a thin laser sheet. For example, by targeting an electronic transition in a molecule, its concentration within the plane illuminated by the laser sheet can be deduced. LÄS MER
4. Multiphase flow measurements using ultrasound
Sammanfattning : In process industries such as for example the oil and gas industry, the paper pulp industry, and the mining industry, multiphase flows are common. It is often of interest to measure the mass fractions of the different phases. LÄS MER
5. Model Based Reconstruction of Ultrasonic Images
Sammanfattning : This thesis is concerned with reconstruction methods for ultrasonic imaging, primarily applied to non-destructive material inspection. In ultrasonic inspection, a specimen is insonified with pulses of high frequency ultrasound, which enters the material and propagates through it. LÄS MER
