Seismic Response Characteristics of High-Speed Railway Hub Station Considering Pile-Soil Interactions by Ning Zhang, Ziwei Chen

“…The results show that the hub station structural system, considering pile-soil interaction, presents the ‘soft-upper-rigid-down’ characteristics as a whole, and the natural vibration is lower than that of the station structure with a rigid foundation assumption. Under the action of three strong seismic motions, the nonlinear site seismic effect is significant, the surface acceleration is significantly enlarged, and decreases with the buried depth. …”

Quick, but Not Dirty: The Usefulness of Flash Mob Studies as a Method for Action Research in eHealth by Kira Oberschmidt, Christiane Grünloh, Stephanie Jansen-Kosterink, Monique Tabak

“…Outcomes show that the flash mob is a potential method for AR, as it is situated in a practical setting where stakeholders can easily be involved, and its pace could speed up the AR cycles. To further improve the applicability for AR, our main recommendations include: promoting the flash mob adequately to increase participation and improve the involvement of 'champions'; tracking interactions outside the flash mob (e.g., comments and questions from bystanders); and choosing an accessible and visible location, taking into account the activities associated with the location.…”
