Solution combustion synthesis is a well–known method around the world. This method is used to manufactured different kind of nanomaterial.Goal of present study is to finding optimize fuel\oxidizer ratio in order to deposition thin film nanocomposite including copper as matrix and alumina as nano particle reinforcement on copper substrate.Broad range of F\O were examined consist of 0.9,1,1.25,1.5 and 1.75 including 25% weight percent of alumina.Products were analyzed using XRD diffraction,thickness measurmnet,time–temperture curves and pin on disc wear test.During the process temperature was recorded as a function of time.Results showed that wear resistant increased four times compared to base state in contrast of base attitude in F\O=1.5.<\div>

This project investigates chaos theory as a method for information cryptography in optical communication. Information security and communicated information error reduction are the main communication issues. Different methods including chaos theory have been suggested for its analysis. In addition to introducing the theory, this article investigates whether it could be used in optical communication and suggests a method to use the theory in the communication.
