Abstract Underground excavation is required for mining engineering and nuclear waste repository. As the progresses, stress increases, brittle failures frequently exist. Brittle are arranged into two types: spalling rock bursting. Spalling in shape of a V-notch may severely damage machine workers involved its development. This potential hazard can be mitigated by fully representing all parameter...

The ability to form freestanding oxide membranes of nanoscale thickness is great interest for enabling material functionality and integrating oxides in flexible electronic photonic technologies. Recently, a route has been demonstrated forming conducting heterostructure LaAlO3 SrTiO3, the canonical system electronics. In this route, epitaxial growth on SrTiO3 resulted strained state that relaxed...

Conventional practices of bridge visual inspection present several limitations, including a tedious process analyzing images manually to identify potential damages. Vision-based techniques, particularly Deep Convolutional Neural Networks, have been widely investigated automatically identify, localize, and quantify defects in images. However, massive datasets with different annotation levels are...

Concrete has good fire resistance. However, once exposed to rapidly increasing temperatures, concrete may suffer from thermal stress-induced spalling or pore pressure-induced spalling. Compared with normal-weight (NWC), lightweight aggregate (LWAC) a low conductivity and is more prone cause higher temperature gradient under the action of high temperatures. This poses hidden concern safety gener...

Viscoelastic elements of Kelvin-Feugt type are supposed to be used for modelling dynamic influences from the transport side and behaviour separate whole structure as a whole. Periodic monitoring bridge crossings using considered approaches will make it possible detect presence defects in span itself, associated with formation cracks, spalling, because such estimated frequencies change.
