in this research the experimental and theoretical studies on different enhanced oil recovery (eor) techniques, i.e. water flooding (wf), gas injection (gi) and water alternating gas process (wag) were performed on specimens taken from an iranian carbonate offshore reservoir at the reservoir condition. the experimental results for each specified techniques were compared with the corresponding re...

Macdonald's criticism of structural models of mobility is empty because it denies ideas or theories a place in model con'struction. Specifically, the equivalent models proposed by Macdonald do not meet the criterion of minimal asymmetry that was applied in the selection of models for British and American mobility tables. Under certain conditions, equivalent models meet the symmetry criterion, b...

Abstract- Efficient message delivery in city environment is required to ensure driver’s safety and passenger’s comfortability. In cities of developed nations, routing of data in vehicular Ad hoc Network (VANET) faces many challenges such as radio obstacles, mobility constraints and uneven nodes distribution. These factors primarily makes communication between vehicles complex. To overcome and t...

mobile ad hoc networks (manets) are composed of mobile stations communicating through wireless links, without any fixed backbone support. in these networks, limited power energy supply, and frequent topology changes caused by node mobility, makes their routing a challenging problem. tora is one of the routing protocols that successfully copes with the nodes’ mobility side effects, but it doesn’...
