Most of Iranian oil reservoirs, usually fractured carbonate, are in the end of primary or secondary recovery. Enhanced oil recovery methods are required for obtaining more performance from these resources. It seems to obtain more oil from reservoirs by flooding polymer after water flooding due to persistence of polymer effect, so the cost remain low. In this project, at the first the theory of water flooding and polymer flooding is described and after that we have done the following steps: •Injection of water into the plugs and calculate secondary recovery •Injection of polymer samples with 700 ppm concentration into the plugs •Injection of polymer samples with 1500 ppm concentration into... 

Analog to digital converters with different specifications are widely used in modern electronic circuits. The significant demand on pipeline converters in several low power applications is mainly due to their high speed and high resolution characteristics. Fast and simple design of analog circuits using CAD tools, is highly sought after by integrated circuit designers. In this thesis, pipeline analog to digital converters is studied and a CAD tool is proposed for transistor level design and optimizations. The main advantage of this design in comparison with the previous works is that the yield and power consumption are considered as optimization factors. The module operates in three parts:...
