Global modelling of the early Martian climate under a denser CO2 atmosphere: Water cycle and ice evolution [PDF]
Icarus 222 (2013), pp. 1-19, 2012 We discuss 3D global simulations of the early Martian climate that we have performed assuming a faint young Sun and denser CO2 atmosphere. We include a self-consistent representation of the water cycle, with atmosphere-surface interactions, atmospheric transport, and the radiative effects of CO2 and H2O gas and clouds taken into account.

The Vibration Characteristics of Ground of Rock Blasting in Silt-Rock Strata
Shock and Vibration, 2021 As the shield section passes through the silt-rock strata, the rock stratum of the tunnel section has to be blasted into blocks in advance, and the diameter of the blocks should be less than 30 cm after breaking, and then, the blocks could smoothly enter

Geology prediction based on operation data of TBM: comparison between deep neural network and statistical learning methods [PDF]
2019 1st International Conference on Industrial Artificial
Intelligence (IAI), 2018 Tunnel boring machine (TBM) is a complex engineering system widely used for tunnel construction. In view of the complicated construction environments, it is necessary to predict geology conditions prior to excavation. In recent years, massive operation data of TBM has been recorded, and mining these data can provide important references and useful ...
