Background: With more and more blockages in the drainage pipe, recent patents on the design of the pipe cleaning device are also being addressed increasingly. But the current pipe cleaning device has only a single dredging function, and due to the inefficiency of the nozzle head, it cannot be used for cleaning of the seriously blocked pipelines. Objective: In order to solve these problems, a novel pipe cleaning device Read More

Background: With the improvement of the properties of plastic products, people gradually realize that the mixing capacity of extruders cannot meet the requirements of fully mixing materials, especially for nano-composites, colored products. In order to improve the mixing level of materials, static mixers are widely used. Researchers developed different types of static mixers to meet the purpose of homogenizing di Read More

Purpose: The purpose of this paper was to design an intelligent controller of ship motion based on sliding mode control with a Radial Basis Function (RBF) neural network optimized by the genetic algorithm and expansion observer. First, the improved genetic algorithm based on the distributed genetic algorithm with adaptive fitness and adaptive mutation was used to automatically optimize the RBF neural network. Then, with th Read More
