12. Blended cognitive behavior therapy : efficacy and acceptability for treating depression in the adult and adolescent population
Sammanfattning : Depression is the most burdensome disorder worldwide in terms of health loss. The potential of internet and technologies to scale up psychological treatment resources is substantial. LÄS MER
13. On Gate Drivers for MOS-Controlled Power Devices and dv-dt Filters for Train Traction Converters
Sammanfattning : In this thesis, low-loss gate-drive solutions and a proposed dv/dt-filter have been investigated with focus on train traction converters with dv/dt constraints.By using the silicon carbide (SiC) junction field-effect transistor (JFET), the switching losses can be significantly reduced compared to the commonly used insulated-gate bipolar transistor (IGBT), but complex gate-driver solutions are required for high utilization in terms of loss reduction.

14. Patient Outcomes after Radiotherapy of Prostate Cancer. Impact of Absorbed Dose and Treated Volume
Sammanfattning : Abstract Backgound Prostate cancer is the most common form of cancer in men in Sweden. Radiotherapy, including external beam radiation therapy (EBRT) and brachytherapy (BT), is important treatment alternatives to surgery and active surveillance. LÄS MER
15. The effect of spacecraft charging on low-energy ion measurements around comet 67P/Churyumov-Gerasimenko
Sammanfattning : A spacecraft in space interacts with the surrounding environment and aqcuires an electrostatic potential. Charged particles are constantly bombarding the surface of the spacecraft, and at the same time solar EUV radiation induces photoemission, causing electrons to be emitted from the surface. LÄS MER
