16. Ductility of Tie Connections in Precast Structures
Abstract : Precast concrete structures are normally provided with tie connections that make it possible to transfer tensile forces across the joints. The tie connections are essential for the structural integrity and can contribute to the formation of alternative load-bearing systems in case of local damages of the structure. READ MORE

17. Generation and metrology of ultrashort pulses and their application in attosecond science
Abstract : This thesis deals with the dynamical processes in atoms and small molecules initiated by the absorption of ultrashort, coherent light pulses. The studied phenomena takeplace on the femtosecond (1 fs = 10−15 s) and attosecond (1 as = 10−18 s) timescales and critically depend on the properties of the light fields that drive them. READ MORE

19. Properties and Long-Term Performance of Internal Interfaces in Composite Insulators
Abstract : An important component that secures durability of composite insulators for high voltage applications is the quality of internal interfaces. Weak interfaces, in form of a reduced bonding or a loss of the adhesion between the insulation components, can be devastating for the long-term functionality of an insulator. READ MORE

20. Analysis of rock stress and rock stress measurements with application to Äspö HRL
Abstract : The process of choosing a site for a nuclear waste repository means that many aspects have to be taken into consideration. One of these is that the repository has to be mechanically stable for a long time. The mechanical stability of the rock is very difficult to determine. READ MORE
