Crack detection on bridges is an important part of assessing whether a bridge safe for service. The methods using manual inspection and bridge-inspection vehicles have disadvantages, such as low efficiency affecting road traffic. We conducted in-depth study bridge-crack proposed crack identification algorithm Unet, called the CBAM-Unet algorithm. CBAM (Convolutional Block Attention Module) ligh...

This paper demonstrates the viability of in-situ transmission electron microscopy for studying the deformation mechanisms of polymer nano-composites. In-situ straining studies are performed on carbon multiwalled nanotube (MWNT)-polystyrene composite films. The experiments show that load transfer across the nanotube-polystyrene interface is operative well into the plastic deformation regime of t...

To meet with the requirement in virtual rendering, an OpenFlight mesh generation method based on B-Rep model is proposed. The bridge construction method, which is flexible for arbitrary multi-loop regions, are employed on model planes. In order to get the closed parametric region for the curved surface, Boolean trimming operations between surface grids and boundary poly-lines are implemented ef...

Adjustable throat-area expansion valves (ATAEV) are functioned as area regulator control units. In literatures, there are many expansion valves normally used in automotive air-conditioning systems, as regulator and electrical type valves. Nevertheless, a review study for such issue has not been introduced, according to the best of author knowledge. The present paper presents a review study for ...
