Abstract: Provided is an evaluation method of ductility of a grouted rock mass for advanced renovation of a water-sand mixture inrush prevention area including following steps: first, acquiring a spatial distribution law of cracks in overlying strata, and establishing a three-dimensional geological model and a grouted rock mass unit geological model; calculating rock mass quality standard of the target rock strata; performing compression tests on multiple groups of grouted consolidated bodies, and calculating an average value of strain softening indexes of the multiple groups of grouted consolidated bodies; selecting multiple groups of grouted target rock strata, and calculating an average value of unstable fracture ductility of the multiple groups of grouted target rock strata; finally, acquiring a permeability strength of the grouted rock mass, and calculating and grading an evaluation index of ductility of the grouted rock mass,

Abstract: A first device comprising a transceiver module configured to begin transmission of a first signal to a second device. A control module is configured to, in response to the transceiver module receiving a second signal during the transmission of the first signal to the second device, determine whether the second signal corresponds to crosstalk by having the transceiver module suspend the transmission of the first signal. In response to the transceiver module continuing to receive the second signal subsequent to the transceiver module having suspended the transmission of the first signal to the second device, the control module determines that the second signal does not correspond to crosstalk. In response to the transceiver module not continuing to receive the second signal subsequent to the transceiver module having suspended the transmission of the first signal to the second device, the control module determines that the second signal does correspond to crosstalk.
