Blasting is widely used in mining, subway, demolition and groundwater-sealed tunnel, among them, the last one is widely concerned because of its many adjacent tunnels, high anti-seepage requirements, strict blasting control, etc. The identification of bl
It is commonly known that a number of variables, including price, supply levels, time, and green level, affect how quickly certain things are in demand. Furthermore, the inventory carrying cost is considered to be a nonlinear representation of time and i

The BPSK modulation technique is determined according to the sign of the real value of the symbol; hence, if many symbols have a real value close to the origin, the probability of an error increases. Because the output SNR of the temporal diversity method is lower than that of the beam ...
Groundwater endmember concentrations are shown on the left with the standard error of the estimate indicated after the ± symbol. Mean, salinity-unmixed, coastal groundwater concentrations are shown on the right with the standard deviation shown after the ± symbol and the number of samples ...

The second step is maximum likelihood decoding, which is performed by projecting the mean-subtracted received symbol on the time-series symbols y0 and y1, which represent bits ‘0’ and ‘1’, respectively, as per the equation: $$b=\mathop{{{\arg }}\,{{\max }}}\limits_{k={{{\math...
