NUMERICAL SIMULATION OF BLAST VIBRATION AND CRACK FORMING EFFECT OF ROCK-ANCHORED BEAM EXCAVATION IN DEEP UNDERGROUND CAVERNS

Numerical Simulation of Blast Vibration and Crack Forming Effect of Rock-Anchored Beam Excavation in Deep Underground Caverns

Aiming at surrounding rock damage induced by dynamic disturbance from blasting excavation of rock-anchored beam in rock mass at moderate or far distance in underground cavern, numerical model of different linear charging density and crustal korpskaft stress in underground cavern is established by adopting dynamic finite element software based on bo

The temporal cost of deploying attention limits accurate target identification in rapid serial visual presentation

Abstract Lag-1 sparing is a common exception to the attentional blink, where a target presented directly after T1 can be identified and reported accurately.Prior work has proposed potential mechanisms for lag 1 sparing, including the boost and bounce model and the attentional gating model.Here, we apply a rapid serial visual presentation task to in
