Main Features of a modern Wire Rod Mill IspatGuru

Jan 03, 2014 Modern wire rod mills are high speed mills capable of rolling of smaller dimensions at high production rates, while at the same time keeping investments and operating costs at the reasonable levels. As a rule, wire rod mills are designed for an annual output of between 300,000 t and over 800,000 t (two strand mills).

Processing approximate aggregate queries in wireless

Dec 01, 2006 In-network data aggregation has been recently proposed as an effective means to reduce the number of messages exchanged in wireless sensor networks. Nodes of the network form an aggregation tree, in which parent nodes aggregate the values received from their children and propagate the result to their own parents.
