In this work, a compact fiber-optic 3D shape sensor consisting of two serially connected 2°
tilted fiber Bragg gratings (TFBGs) is proposed, where the orientations of the grating planes …

In order to investigate the actual health condition of asphalt concrete pavements on widened
road embankments, a full-scale model test study was conducted. A fiber Bragg grating …

Temperature is one of the most significant parameters influencing heavy-duty machine tool
accuracy. In order to model the correlation between temperature field distribution and …

Owing to the increasing needs for robust highway pavement structural monitoring tools with
