TBMs can excavate tunnels using a circular cross-section that drills through soil and rock strata, seamlessly laying concrete segments to construct tunnels, subway tubes and sewer lines.

Seabed-origin oil spills pose distinct challenges in marine pollution management due to their complex transport dynamics and ...

A technique for fabricating silica channel waveguides with circular cross sections is presented. The geometrical mismatch between a square or rectangular waveguide and a regular optical fiber is ...

A novel giant electro-rheological fluid damper is designed and manufactured, which works on a shear-flow mixed mode, and the Bingham mode has been used for the damping force modelling. To better study ...
