in this paper, the removal of phenol by using aqueous solution in a low pressure reverse osmosis membrane was investigated. the effect of feed pressure, feed concentration, feed flow rate and feed ph on phenol rejection was investigated. the results showed that feed ph is the most affective parameter on the phenol rejection. rejection of phenol increased with increasing ph from 2 to 10 under th...

Fab-less business model in semiconductor industry has led to serious concerns about trustworthy hardware. In untrusted foundries and manufacturing companies, submitted layout may be analyzed and reverse engineered to steal the information of a design or insert malicious Trojans. Understanding the netlist topology is the ultimate goal of the reverse engineering process. In this paper, we propose...

The large reverse flow region of the rotor with a high advance ratio is an important factor that affects performance improvement helicopters. This paper examines dynamic stall airfoil in to develop set pressure measurement systems for low region. pitch oscillation experiment NACA0018 and out has been carried out, influence motion parameters on stalls studied. results show more likely under stat...
