1. Studies of excitation modes of atomic nuclei by means of magnetic moment determinations and general decay investigations : construction of an instrument for determinations of electromagnetic moments of nuclei by angular correlation methods
Sammanfattning : .... LÄS MER
2. Purification, Stereoisomeric Analysis and Quantification of Biologically Active Compounds in Extracts from Pine Sawflies, African Butterflies and Orchid Bees
Sammanfattning : Stereochemistry plays an important role in nature because biologically important molecules such as amino acids, nucleotides and sugars, only exist in enantiomerically pure forms. Semiochemicals carry messages, between the same species (pheromones) and between different species (allelochemicals). LÄS MER
3. Laser welding of boron steels for light-weight vehicle applications
Sammanfattning : Laser beam welding has gained a significant interest during the last two decades. The suitability of the process for high volume production has the possibility to give a strong advantage compared to several other welding methods. However, it is important to have the process in full control since various quality issues may otherwise occur. LÄS MER
4. Laser welding of ultra-high strength steel and a cast magnesium alloy for light-weight design
Sammanfattning : There is a strong industrial need for developing robust and flexible manufacturing methods for future light-weight design. Better performing, environmental friendly vehicles will gain competitive strength from using light weight structures. LÄS MER
5. Antenna Evaluation for Vehicular Applications in Multipath Environment
Sammanfattning : Antennas are essential components in any wireless communication system. To evaluate them is challenging, especially when new technologies are emerging.Future intelligent transport systems, where vehicular communications play an important role will cover important aspects such as traffic safety and traffic efficiency.
