Abstract The structural fire safety of tunnels is a highly debated theme at international level. Car accidents in road tunnels, failures on the power lines railway [1,2] and electrical related issues technological installations underground research infrastructures can lead to trigger fire. Fire due cars, trains combustion cable insulations be considerably dangerous. such causes stress increases...

The article covers the problem of determination loads blast wave on aboveground and underground structures. In industrial production, chemical sources explosion occur, for which environment is air. most common typical source solid products (PE) in form a packed charge. explosion, highly compressed heated gaseous are formed volume main parameters shock that determine its effect structure, i.e., ...

Converting the actual scenes into three-dimensional models has inevitably become one of fundamental requirements in autonomous driving. At present, main obstacle to large-scale deployment is high-cost lidar for environment sensing. Monocular depth estimation aims predict scene and construct a 3D map via merely monocular camera. In this paper, we add geometric consistency constraints address non...
