1. Signal Processing for Spectroscopic Applications
Abstract : Spectroscopic techniques allow for studies of materials and organisms on the atomic and molecular level. Examples of such techniques are nuclear magnetic resonance (NMR) spectroscopy—one of the principal techniques to obtain physical, chemical, electronic and structural information about molecules—and magnetic resonance imaging (MRI)—an important medical imaging technique for, e.

2. Signal Transduction in Photoreceptor Proteins : Insights From Time-Resolved X-ray Solution Scattering
Abstract : 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. READ MORE

3. Formation of Mesoporous Materials and their use as Lipid Bilayer Supports
Abstract : Mesoporous materials have acquired great scientific interest in various applications; something that is largely due to that their properties, such as pore size, pore orientation, material composition and surface chemistry, can be controlled to a large extent. One idea, which has been investigated in this thesis, is to use mesoporous materials as supports for lipid bilayers and by doing so fabricate devices that mimic the cell wall and at the same time has sufficient mechanical robustness for practical use.

4. Mechanism of the passive NOx adsorption process on zeolite-supported Pd in controlling cold-start emissions
Abstract : Passive NOx adsorbers (PNA) have been used for preventing NOx emissions being released during a cold start. This method involves trapping NOx on an adsorbent at low temperatures and releasing them later, when the exhaust temperature exceeds 200℃. READ MORE

5. Multivariate Exploration and Processing of Sensor Data-applications with multidimensional sensor systems
Abstract : A sensor is a device that transforms a physical, chemical, or biological stimulus into a readable signal. The integral part that sensors make in modern technology is considerable and many are those trying to take the development of sensor technology further. READ MORE
