Abstract -
The paper presents a framework for the automation of testing of component-based systems and embedded systems by considering test purposes. We deal with the component-based systems from communication point of view. Hence, only the external behavior of the components at the interaction points can be observed. For test generation, we adapt a generic FSM-based method by including test purposes to optimize the amount of the generated test sequences for practicability reasons. These methods have been generically since decades successfully used for testing both hardware and software including protocols and communicating systems.

Abstract -
A Hybrid encode standard H264/AVC is the strongest and most standard encode advanced in encode and data processing used in data compression systems. Modern so as to what possessed of strength and flexibility in the encode of data to be moved, because of platforms used in most applications, in this paper the System intra frame encode and data compression for single works to encrypt and decode the encrypted data display of all kinds of different that the target of the message implementation of all components of the encrypted and encode emulated a practical on-chip FPGA, represented by the implementation of encode and decode the Intra frame algorithm within the time frame (1.294 ms) with frame size (120x160) and consumption of approximately (3714) slides to implement all components of the encoder (integer conversion function, function approximation, inverse transfer function, inverse function approximation), 92% of the chip size within the frequency 68MHZ within the programmer of practical applications ISE version 14.1 company Xilinx and chip Spartan3E (XC3S500E). Note the implementation time can work in real time to encode and decode the videos.

Abstract -
One of the most important decisions for regulatory body is to give a license for increasing or decreasing reactor power or reactor operation. Model predictive control proves its reliability to help the operator and regulatory body to ensure NPP operational safety. This paper introduces a modified model predictive control based on genetic algorithm. It relies on decreasing both the input cost and the difference between real output and optimum output by using a minimizing factor. The results show a reduction in overshoot and settling time of NPP systems parameters, which improve the NPP safety and stability.
