We present a unique, comprehensive dataset that provides the pattern of five activities walking, cycling, taking train, bus, or taxi. The measurements are carried out by embedded sensor accelerometers in smartphones. offers dynamic responses subjects carrying smartphones varied styles as they perform through vibrations acquired accelerometers. contains corresponding time stamps and three direct...

Underwater bubbles are extremely good acoustic resonators, but freely evolving and dissolving. Recently it was found that can be stabilized in frames, the influence of frame shape is still undocumented. Here we first explore vibration polyhedral with a low number faces, shaped as five Platonic solids. Their resonance frequency well approximated by formula for spherical same volume. Then extend ...
