2. Pre-study of optical LED units for shunting signals
University essay from KTH/Hälsoinformatik och logistikAbstract : Alstom wanted to investigate the possibility of adapting its light emitting diode (LED) technology for shunting signals in train traffic. The LED technology uses 50V, but Alstom wants to adapt it for 12V. The LED technology is energy efficient but needs to be adapted for existing signal interlocking by drawing a higher current.

3. Trends in Flooding in Europe and North America - an Extreme Value Approach
University essay from Lunds universitet/Matematisk statistikAbstract : This study examines minimally altered catchments in Europe and North America in order to determine whether any changes to the dynamics of flooding have occurred due to changes in the climate. By examining the parameters of the Generalized Extreme Value (GEV) distributions of in- dividual catchments it is possible to determine not just if changes in flood patterns have occurred, but also the nature of these changes.

4. Trends in Flooding in Europe and North America - an Extreme Value Approach
University essay from Lunds universitet/Matematisk statistikAbstract : This study examines minimally altered catchments in Europe and North America in order to determine whether any changes to the dynamics of flooding have occurred due to changes in the climate. By examining the parameters of the Generalized Extreme Value (GEV) distributions of individual catchments it is possible to determine not just if changes in flood patterns have occurred, but also the nature of these changes.

5. Active rectification and control of magnetization currents in synchronous generators with rotating exciters : Implementation of the SVPWM algorithm using MOSFET technology
University essay from Uppsala universitet/ElektricitetsläraAbstract : This thesis aims to design and build a power electronics system for the rectification and control of magnetization currents in synchronous generators with rotating exciters.The rotating exciter provides three-phase AC while the generator rotor needs DC with a high degree of control.
