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...

Due to invisibility and complexity of the underground displacement monitoring, there exit few practical monitoring sensors capable of monitoring the underground horizontal and vertical displacements simultaneously. A novel electromagnetic underground displacement sensor able to monitor both the horizontal and the vertical displacements was proposed in our previous studies and abbreviated as the...

in recent decades, attention to contamination propagation into soils and underground water has increased, which has led to a rise in the studies on soil contamination problems and methods of in-situ remediation. in this research, effective parameters on oil contamination propagation in soils and underground water have been investigated using fem in order to determine propagation patterns. the m...

Variations in seasonal snowfall regulate regional and global climatic systems and vegetation growth by changing energy budgets of the lower atmosphere and land surface. We investigated the effects of snow on the start of growing season (SGS) of temperate vegetation in China. Across the entire temperate region in China, the winter snow depth increased at a rate of 0.15 cm yr(-1) (P = 0.07) durin...

Measurements of cosmic-ray muon rates and energy deposition spectra in a one tonne liquid scintillator detector at 1070 metres vertical depth in the Boulby underground laboratory are discussed. In addition, the simulations used to model the detector are described. The results of the simulations are compared to the experimental data and conclusions given. The muon flux in the laboratory is found...

Permeability at high temperature is a very important parameter to be considered for designing underground high level nuclear waste repository (HLW) in rock mass. The surrounding rock mass is exposed to heat radiated by HLW when it is buried underground and development or extension of micro-cracks takes place in the host rock due to rise in temperature. Keeping this in view, the permeability stu...
