In this paper, aiming at the water-consuming of the circulating water system in the petrochemical enterprises, the stage-wise super structure model of the heat exchanger network is established. And the model can be solved by using the MINLP programming method. Considering the characteristics of no-shunt and shunt, the simultaneous optimization of heat exchanger networks is implemented, which is based on the stage-wise super structure method. Thus the company's energy saving can be achieved and the consumption goal of the minimum circulating water system can be also realized. The proposed optimization and technology road-map of the industrial water recycling system have an important reference value for the research and application of process optimization.

According to the limitations and shortcomings of BP neural network in estimating the battery state of charge(State of Charge, SOC), such as slow convergence speed and poor generalization, this paper puts forward an improved BP neural network method of battery SOC estimation. Train the improved BP neural network with the experimental data. It compares the trained neural network of SOC with the real values, and uses Matlab to simulate in order to verify the correctness of the algorithm.

In this paper, a novel over-constrained three degree-of-freedom (DOF) spatial parallel manipulator (SPM) is proposed. The architecture of the SPM is comprised of a moving platform attached to a base through two revolute- prismatic-universal jointed serial linkages and one spherical-prismatic-revolute jointed serial linkage. The prismatic joints are considered to be actively actuated. Kinematics and dynamics of the SPM are studied systematically. Firstly, both of the inverse and forward displacements are derived by analytic formulae. Then, the velocities and the accelerations of the moving platform and each limb are obtained. Finally, dynamics of the mechanism is derived based on the principal of the virtual work. The results are illustrated by numerical examples.
This paper, the mechanism of valve electric actuator failures is analyzed, and the fault diagnosis method based on principle component analysis (PCA) and support vector machines (SVM) is put forward. In order to reduc...
