wastewater treatment technology in the cyclic nature of the process that takes a long time. but man tries to rush to their needs with experience and understanding of the natural processes of interaction, and using technology to build their industrial development is authorized. sewage treatment reed have been born from the vision of man's increasing need to water daily decreases the natural reso...

In recent times the explosive growth in computing and networking abilities has occurred. This has caused an increased reliance on distributed computing and process operations across the networks. The main aspect in the process control via network is the network delay, which depends on the network type and protocol. This paper gives the literature review about the network-based control systems a...
