Low Density Parity Check (LDPC) coding is a classical method for the detection and correction of errors. Its problem relatively complex operations which must be performed at encoding, especially decoding, to detect correct errors caused by communication channels. We present solution using regular LDPC Hopfield network-based associative memories. Our solves this an memory based on network decoding stage, stores code words. This tends transform words received with in free improved ability...

The paper proposes an intelligent method for real-time monitoring of the evolution pests in agricultural crop. system consists a pheromone trap, camera that periodically fetches frames with trap and data transceiver module where frame is encapsulated date station id. arrives at server they are retrieved analyzed using two deep learning artificial neural networks. One determines type number other identifies pest population. has been experimented apple tree culture order to early identify combat them.

In this paper the authors propose a solution in which an intelligent algorithm - genetic our case is used to generate commands for robot real time, so that can determine optimal moves considering several aspects: route tracking and low power consumption. Genetic algorithms are solutions multi-criteria optimization using them find problems containing constrictions. However, they were designed as running on computer therefore cannot ensure rapid generation of solutions. On other hand, problem...
