1. Development of a non-destructive testing method for thermal assessment of a district heating network
Abstract : This thesis presents the development of a non-destructive testing (NDT)method for thermal assessment of pre-insulated district heating (DH) pipes with high accuracy, in which the development process from literature review to its present stage is presented and discussed. Pre-insulated DH pipes have been in use for more than 40 years. READ MORE

2. Simulation of runaway electron generation during plasma shutdown by impurity injection
Abstract : Disruptions are dangerous instabilities in tokamaks that should be avoided or mitigated. One possible disruption mitigation method is to inject impurities into the plasma to shut it down in a controlled way. Runaway Electrons (REs) can be generated after the plasma is cooled down bythe impurities and these electrons can damage the tokamak. READ MORE

3. Reducing Energy Consumption through Adaptive Shutdown Scheduling on a Chip-Multiprocessor
Abstract : There is seemingly a never-ending consumer demand for mobileterminals such as cellular phones and personal digitalassistants (PDAs). Each new generation of terminals comes withmore elaborate functions than in the previous generation. READ MORE

4. Low head pumped hydro storage with contra-rotating pump-turbines
Abstract : The increasing share of electrical energy production by intermittent sources pushes the demand for energy storage. Pumped hydro storage (PHS) has a long history of providing a cost-efficient energy storage solution. However, for PHS to be a viable option, a large head is typically required. READ MORE

5. Material migration in tokamaks : Erosion-deposition patterns and transport processes
Abstract : Controlled thermonuclear fusion may become an attractive future electrical power source. The most promising of all fusion machine concepts is called a tokamak. The fuel, a plasma made of deuterium and tritium, must be confined to enable the fusion process. It is also necessary to protect the wall of tokamaks from erosion by the hot plasma. READ MORE
