Authors: Zhang Hai , Li Shixin , Liu Xiaoyu 
Published: June 2020

Abstract
Aiming at the shortcomings of single algorithm such as blind operation, directionless, long calculation time, low accuracy in Genetic Algorithm and poor diversity of population of Particle Swarm Optimization, which is prone to premature and fall into local optimum. In this study, the serial algorithm fusion idea is adopted, and the population evolved from the Genetic Algorithm is taken as the initial population to be executed by the Particle Swarm Algorithm, namely GAPSO algorithm. In view of the drawbacks of the respective algorithms in the execution of GAPSO algorithm, this paper proposes an Improved Genetic Particle Swarm Optimization algorithm, namely IGAPSO algorithm. In this algorithm, the improved GA only optimizes the initial particle once and then gives it to the improved PSO for optimization. Its optimization method and ability are greatly improved, resulting in a rapid increase in convergence speed. In addition, the improved PSO introduces adaptive inertia weight and learning factor, so that the particles can adaptively adjust global search and local search, and adaptively balance the influence of self-experience and social experience, which greatly avoids falling into local optimization problem and makes the solution more accurate. Through the verification of test functions, GAPSO has obviously improved the calculation accuracy, convergence speed and global stability compared with a single algorithm, while IGAPSO has also improved the convergence accuracy and speed compared with GAPSO, especially in multi-peak functions.

Abstract
Renewable energy sources are beneficial to provide clean power generation but simultaneously brings power supply risk due to natural uncertainties. A hybrid wind-solar-hydro generation system, which takes advantage of the complementary characteristic of renewable energy sources, is capable to supply the power demand reliably. A multi-objective model of the hybrid system is proposed to achieve minimum power supply risk and maximum economic benefit under natural limitations. To handle natural uncertainties, autoregressive integrated moving average model is applied to produce typical daily models of weather conditions in different scenarios.

The study has shown that the hybrid system does not crash reliability but increases economic benefit, it’s necessary to reserve wind and solar generation, wind generation needs to cooperate with hydro generation according to water dispatching.

As you can see, the hybrid model based on Connectionist Temporal Classification (CTC)/Attention has very prominent advantages in decoding, which can combine the excellent sequence-to-sequence modeling ability of attention, and can also combine CTC to achieve temporal alignment. We propose SA-Conv-CTC/Attention model, which apply a Self-Attention and shallow Convolution based hybrid encoder to Hybrid CTC/Attention Architecture, and we also explored the method of decoding with Self-Attention language models. The CTC network sits on top of the encoder and is jointly trained with the attention-based decoder, even participated in decoding. We achieve a 0.8-4.75% error reduction compared to other hybrid CTC/Attention systems on WSJ and HKUST dataset.

Authors: Zhu Yongyong , Liu Bao , Zhang Kai 
Published: June 2020

Abstract
An indirect boundary element method using discrete sound field of virtual sound source is used to calculate the acoustic and vibration coupling response of the stiffened plate in water. In this paper, the relationship between the structural vibration mode coefficient and the virtual sound source intensity is established by using the superposition principle through Fourier transform using structural dynamics equations and boundary compatibility condition satisfying the function of virtual sound source intensity. Once the virtual sound source intensity is obtained, the radiation power can be determined. Taking the simply supported rectangular thin plate as an example, the sound radiation power is calculated on the condition that surface velocity is unknown, and the results are compared with the results of the analytical method, which shows that the method has high accuracy.

Published: June 2020

Abstract
As one of the important components of modern microfluidic devices, micromixers have attracted more and more attention. Among many microfluidic mixers, electro-osmotic flow mixers have been widely studied and applied due to their advantages such as simple structure, convenient control and remarkable mixing effect. In this paper, a two-dimensional numerical model of an electro-osmotic flow micromixer with an annular mixing chamber is established by means of the simulation software COMSOL Multiphysics. The mixing process of fluid in the electro-osmotic flow micromixer is simulated, and the flow characteristics of fluid in the micromixer are analyzed. The analysis shows that the electroosmotic flow micromixer generates electroosmotic flow under the action of alternating electric field, and disturbs the fluid to form vortex, thus greatly improving the mixing efficiency. The results show that the micromixing efficiency increases with the increase of zeta potential and applied alternating electric field potential, and in a certain range, the micromixing efficiency increases first and then decreases with the increase of alternating electric field frequency.

Abstract
Recently, with the rising proportion of new energy installed capacity in China, the problem of new energy consumption in the northwest region is particularly prominent, and the phenomenon of abandoning wind power and solar power is serious. In order to alleviate this situation, this paper proposes an annual maintenance plan optimization method for new energy consumption. Under the premise of considering the new energy output, the goal is to minimize the limited power of new energy generation and the minimum cost of maintenance. Transmission maintenance planning model is mixed integer linear programming model and can be solved by a solver such as CPLEX. The feasibility of the method is verified by a provincial power grid example, which effectively reduces the limited power of new energy generation.
