Membrane fouling reduces wastewater treatment efficiency and cause financial and energy costs to some extent. The size of membrane flux reflects the degree of membrane pollution. Make timely cleaning membrane or replacement membrane decision to maintain considerable treatment effect on the basis of the membrane flux. particle swarm optimization (PSO) algorithm can quickly find the global optimum. Genetic algorithm (GA) has the property of global convergence. The prediction model used in this paper is based on the PSO-GA hybrid algorithm. The combination of these not only improves the convergence speed of genetic algorithm but also reduces the probability of particle swarm optimization algorithm falling into local optimum. Elman neural network acts as the basic network. Compared with Elman neural network and BP neural network, the prediction accuracy of PSO-GA-Elman is improved.

A PI (proportional integral) control parameter optimization method based on particle swarm optimization improved grey wolf algorithm is proposed to address the issues of insufficient parameter adjustment accuracy, slow response speed, and poor stability in traditional PI control for permanent magnet synchronous motors (PMSM). To improve the issue of the traditional grey wolf optimization algorithm easily falling into local optima and causing a decrease in accuracy, the position update strategy of the particle swarm algorithm is applied to the position update of the grey wolf algorithm, effectively enhancing the global optimization capacity of the grey wolf algorithm. By establishing a simulation model of the PMSM vector control system and conducting hardware-in-the-loop experimental tests, the motor system response of the improved grey wolf algorithm and traditional PI control is compared and analyzed. The results show that compared to optimizing PI control parameters using traditional methods, the improved grey wolf algorithm significantly enhances the response speed, anti-interference capability, and robustness of the PMSM control system. © 2023 ACM.

Under the limit of engineering investment, the aseismic optimum design of pipeline system is used to minimize the sum of aseismic cost. Since optimal problem is an nonlinear hybrid model which involves dual "curse of dimensionality" during the mathematical programming and system reliability calculation, traditional optimal techniques can hardly solve the problems of distribution of aseismic engineering investment for lifeline network system. Evolutionary-based particle swarm algorithm has been investigated and the improved design of inertia weight has been fulfilled in this paper. A new hybrid particle swarm algorithm makes use of the ergodicity of chaos to improve the capability of precise search and keep the balance between the global search and the local search. Combining with Boolean cubical matrix disjoint calculation method used as aseismic reliability analysis tool of network system, the improved algorithm is applied to the optimization solution of investment distribution for gas pipeline network The analysis of an example in a certain pipeline network system demonstrates that the established model and algorithm can achieve better convergent performance and speed.

Traditional battery thermal models either lack accuracy or have high computational costs, making it difficult for battery management systems to monitor battery temperature online. In this study, a three-dimensional thermal network model was developed specifically for a 120Ah square lithium-ion battery, significantly reducing the computational burden while ensuring relatively accurate outputs at multiple temperature points. Firstly, the heat generation rate of the entire battery during charging and discharging processes was obtained using an accelerated adiabatic calorimeter (ARC). Then, based on the positions of the electrode tabs and temperature measurement points, the battery was divided, and a three-dimensional thermal network model architecture was constructed. Special particle swarm algorithms and neural networks were used to fit the thermal parameters of the thermal network model. Finally, discharge temperature experiments were conducted to validate the feasibility of the thermal network model. © 2023 IEEE.

In order to solve the problem that the period of designing metasurface with specific functions is too long by using electromagnetic simulation software, this paper proposes a metasurface design method based on artificial neural network, which can accurately predict the far-field pattern. In the training process, the root-mean-square error decreases with the increase of the number of iterations, the minimum root-mean-square error is 0.01, and the training time is 21 s. After the training is completed, the model can quickly predict the far-field pattern according to the coding matrix. The single prediction time of the neural network is 0.0065 s, while the single simulation time of the full-wave simulation software is 4 min, which is far more than that of the neural network. The accuracy of the predicted data is verified by comparing the predicted results with the results of the full-wave simulation. By combining the neural network with particle swarm optimization algorithm, the metasurface coding matrix corresponding to the target pattern can be designed. Compared with the traditional metasurface design method, this design method greatly reduces the design time and solves the problems of time consuming and cost in the traditional design method.
