16. Security of Time Synchronization for PMU-based Power System State Estimation: Vulnerabilities and Countermeasures
Abstract : Phasor Measurement Units (PMUs) constitute an emerging technology that is essential for various smart grid applications such as phase angle monitoring, power oscillation damping, fault localization, and linear state estimation. To obtain precise PMU measurements of voltage and current phasors, time synchronization in the order of 1 microsecond is typically required. READ MORE

20. Towards model-based development of heavy truck synchronizers
Abstract : Gear shifts are becoming more and more important as engines are adapted to low speed and high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to future engines and thus new working conditions, improved development tools are needed. READ MORE
