1. Fast wave heating and current drive in tokamaks
Sammanfattning : This thesis concerns heating and current drive in tokamak plasmas using the fast magnetosonic wave in the ion cyclotron range of frequencies. Fast wave heating is a versatile heating method for thermonuclear fusion plasmas and can provide both ion and electron heating and non-inductive current drive. LÄS MER
2. Hydrodynamic Modelling for a Point Absorbing Wave Energy Converter
Sammanfattning : Surface gravity waves in the world’s oceans contain a renewable source of free power on the order of terawatts that has to this date not been commercially utilized. The division of Electricity at Uppsala University is developing a technology to harvest this energy. LÄS MER
3. Premolar autotransplantation in orthodontic treatment : a clinical and radiographic long-term study
Sammanfattning : Premolar aplasia and avulsed or malformed anterior teeth are common in young people. Using autotransplantation, it is possible to move problems in the dental arches to regions where they are more easy to solve orthodontically. LÄS MER
4. X-ray Phase Contrast Tomography : Setup and Scintillator Development
Sammanfattning : X-ray microscopy and micro-tomography (μCT) are valuable non-destructive examination methods in many disciplines such as bio-medical research, archaeometry, material science and paleontology. Besides being implemented at synchrotrons radiation sources, laboratory setups using an X-ray tube and high-resolution scintillation detector routinely provide information on the micrometre scale.

5. Mechanical Modelling of Powder Compaction : Due to Corona is not possible to attend this defense in person, instead attend via this link: https://play.kth.se/media/t/0_mbkr2jhi
Sammanfattning : Cutting tool inserts, for instance used in steel machining, have the requirement to be toughand are therefore most often manufactured out of cemented carbides, using powdermetallurgy. Manufacturing components with powder metallurgy has its advantages in highproductivity and good net shape. LÄS MER
