1. Laser on kinetic operator
Sammanfattning : This thesis highlights a variety of aspects within the field of mobile robots. The hinge is system architecture for mobile robots. For a mobile robot to be put into operation all necessary systems have to be functioning and control mechanisms have to be established. The robot may be set to operate autonomously as well as remotely controlled. LÄS MER
2. Continuous Welded Railway Rails: Residual Stress Analyses, Fatigue Assessments and Experiments
Sammanfattning : Railway rails are today often continuously welded. This type of joint generally requires less maintenance than is needed for the bolted joints. It has also reduced wheel damage and made the ride more comfortable. However, these joints are subject to damage. LÄS MER
3. Statistical processing of Flash X-ray Imaging of protein complexes
Sammanfattning : Flash X-ray Imaging (FXI) at X-ray Free Electron Lasers (XFELs) is a promising technique that permits the investigation of the 3D structure of molecules without the need for crystallization, by diffracting on single individual sample particles.In the past few years, some success has been achieved by using FXI on quite large biological complexes (40 nm-1 μm in diameter size).

4. Heat transfer,inclusion characteristics and fluid flow phenomena during up-hill teeming
Sammanfattning : Clean steel production requires good control of the sizedistribution and the composition of the inclusions at allstages of the steel making process. So far, there exists verylittle information on the behavior of the inclusion populationduring ingot casting of steel. LÄS MER
5. Investigations of the Kinetics of Reduction and Reduction/Carburization of NiO-WO3 Precursors
Sammanfattning : Kinetic studies of reduction of the mixtures of NiO and WO3 having different Ni/(Ni+W) molar ratios in flowing hydrogen gas were investigated by means of Thermo Gravimetric Analysis (TGA), Fluidized Bed (FB) technique as well as Thermal diffusivity measurements under isothermal conditions. In the case of TGA, the reaction progress was monitored by mass loss, while evolved gas analysis by a gas chromatograph was the indicator of the reaction progress in the case of FB. LÄS MER
