This research involves the design and analysis of pinch-based water/wastewater networks to minimize water utility in the petrochemical and petroleum industries. A study has been done on Tehran Oil Refinery to analyze feasibilities of regeneration, reuse and recycling of water network. COD is considered as a single key contaminant. Amount of freshwater was reduced about 149m/h (43.8%) regarding ...

Public utility services matter. Around the world, access to clean water and sanitation facilities, effective telecommunications and Internet services and reliable energy and transport services are indispensible to individuals, societies and economies.

Lack of adequate information to determine water allocations, environmental flow requirements and the increasing intensity of cropping systems require a better seasonal distribut...

In this paper, the concept of MIMO is integrated with the existing cognitive radio network to enhance the communication utility of the secondary user. Water filling algorithm based power control is proposed to improve the transmission capacity of the cognitive system without degrading the primary user’s quality of service. Considering the interference constraint of the primary user, an optimal ...
