A Wireless Sensor Network (WSN) is one that is in continual interaction with its environment, and executes at a pace determined by that environment. The use of rigorous formal method in specification and validation can help designers to limit the introduction of potentially faulty components during the construction of the system. Due to their complex(More)
In this paper, we present a robust approach of automatic detection and recognition of road signs in national roads, starting from the images resulting from a video stream taken by a camera embarked on a vehicle. Our approach is composed of three main phases: the first phase is to extract video stream images containing a circle or a triangle. This extraction(More)
—This paper introduces two decoders for binary linear codes based on Metaheuristics. The first one uses a genetic algorithm and the second is based on a combination genetic algorithm with a feed forward neural network. The decoder based on the genetic algorithms (DAG) applied to BCH and convolutional codes give good performances compared to Chase-2 and(More)
