1. 1. Runaway electrons and Alfvén eigenmodes in tokamaks

   Författare :Håkan Smith; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; two-way diffusion equation; compressional Alfvén eigenmode; fusion plasma physics; tokamak disruption; runaway electron; Alfvén cascade;

   Sammanfattning : Runaway electrons can be generated as a consequence of the rapid thermal quench of the plasma in a tokamak disruption. If the time scale of this cooling is short compared to the collision time in the tail of the electron velocity distribution, incomplete thermalisation of this tail leads to a burst of runaway production.

5. 4. Essays on R&D and Growth

   Författare :Henrik Braconier; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; International commerce; Technology; Scale effects; Innovation; Imitation; R D; Endogenous Growth; Internationell ekonomi;

   Sammanfattning : The purpose of this study is to analyze some aspects of the relationship between R&D and economic growth. In Chapter 2 we analyze how costly imitation may be incorporated into an R&D-driven endogenous growth model. In the model, optimizing firms allocate resources to innovation or imitation. LÄS MER
