In this work, thermal deep drawing and thermoelectric coupling tests were performed on an annealed ZK60 magnesium alloy sheet to investigate the effect of pulse current formability during process. The effects forming drawn parts studied, changes thinning rate hardness obtained. results showed that using improved increased ultimate depth drawing. value part overall increasing trend, followed by ...

Hydraulic fracturing is a technique to extract oil and gas from shale formations, obtaining uniform proppant concentration along the fracture key its productivity. Recently, various model predictive control schemes have been proposed achieve this objective. But such controllers require an accurate computationally efficient which difficult obtain given complexity of process uncertainties in rock...

In studies of irrigation and drainage projects for drainage, it is necessary to extend the data from the sampling point to the network. Therefore, based on available data from observational wells, estimating the state of hydraulic conductivity (K) in the surrounding area. The estimation process values for locations where there is no information for them based on viewing areas called wells spati...
