1. Oscillation Mark Formation in Continuous Casting Processes
Sammanfattning : .... LÄS MER
2. QCM-D with focus on variations in oscillation amplitude
Sammanfattning : The QCM-D (quartz crystal microbalance with dissipation monitoring) technique is an increasingly popular tool in studies of molecular interactions at interfaces, e.g. binding/unbinding reactions at surfaces, studies of thin film properties, and conformational changes. LÄS MER
3. Power System Oscillations - Detection, Estimation and Control
Sammanfattning : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. LÄS MER
4. On the Load Distribution and Design of a Chain Drive
Sammanfattning : Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. LÄS MER
5. Laser-Driven Particle Acceleration - Improving Performance Through Smart Target Design
Sammanfattning : Laser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the ~10 MeV regime. LÄS MER
