Abstract During track construction or ballast bed maintenance, layer compaction quality plays an essential role in the following irregularity accumulation, its lifecycle, and maintenance costs. The process is characterized by accumulation of stressed state. elastic wave propagation methods are effective way for identification properties. paper presents theoretical experimental studies consolida...

Movers and Shakers is a tablet-based serious game that explores how subversive game design can foster meaningful conversational conflict beyond outside the game’s digital screens. This twoplayer strategy puzzle was developed at the Singapore-MIT GAMBIT Game Lab and is used as a research tool to explore novel challenges in multiplayer serious games.
