As a friendly biometric method, face recognition has the advantages of not easy to forge, easy to obtain, and high accuracy. The paper builds a development environment for embedded face recognition. In terms of hardware, the embedded development board and camera of the ARM architecture are chosen; in terms of software, the open source Linux operating system is chosen. The virtual machine was installed on the PC, the cross-compilation environment was established, and the kernel, driver and other related ports were transplanted on the development board, which established a stable running environment for the design and development of the face recognition application. An embedded system pooling-patch algorithm based on deep learning pooling operation and Deep ID algorithm is proposed. Experiments on the ORL face database and the face image library of our lab members show that the method not only has a high recognition rate but also takes a short time.

Considering the fact that the optimization of operation process of CCHP microgrid is complex, characterized with uncertainties, nonlinearity, strong coupling and dynamics. This paper proposes a method for optimal operation of CCHP microgrid system based on ADHDP (action based heuristic dynamic programming) to solve this problem. ADHDP involves three neural networks, namely the Action Network, Critic Network and Model Network. The Critic network weights keep being updated inline with the control error and performance index function. In addition, the action network weights keep being updated inline with the control error. The ADHDP model is trained with real-time data of the system until an optimal control strategy of CCHP microgrid is obtained. In the end, the simulation results suggest that the proposed scheduling method has effectively reduced the total electricity cost and improved energy efficiency.

In this paper, a semi-analytical method for acoustic black hole cantilever beams is presented. Based on Euler-Bernoulli beam theory, the governing equation of the free vibration of the variable section beam is derived. The finite difference method (FDM) is used to solve the equation. The mode shape and nature frequency of the one-dimensional acoustic black hole (ABH) cantilever beam is obtained, and the error between the result and the finite element result is within 1%, which proves that the method has high precision. The effects of various parameters of ABH beam on natural frequency and mode shape are studied. The results show that as the exponent m increases, the natural frequency decreases. The higher the order, the lower the percentage. The thickness of the free end hn increases, the natural frequency increases, and the higher the order, the greater the increase. Moreover, m and hn have a certain influence on the node and amplitude of the mode. The semi-analytical method in this paper is simple and efficient, with good accuracy and convergence. The parameterization is convenient, and its good programmability is very convenient, which means that it provides a simple and efficient new method for parameterization and optimization design of the acoustic black hole beams.

Based on the mathematical model of the current filament method in induction coil gun, the factors of inductance matrix in the mathematical model are studied. The schemes of sparsing mutual inductance gradient matrix and inversing the matrix by block iterative and order reduction are used to shorten the time of the current filament method simulation model while maintaining reliability. In order to verify the validity and reliability of the improved current filament simulation model, the 25-stage, 50-stage and 100-stage induction coil guns are taken as the research objects respectively. The results of the current filament method simulation model before and after improvement are compared. The effectiveness and reliability of the improved current filament method are verified. In order to further study the influence of the sub-schemes, the 50-stage and 100-stage induction coil guns are taken as the research objects, and the influence of each sub-scheme is analyzed by the control variable method. It can be seen from the results that inversing the matrix by block iterative and order reduction is better than sparsing mutual inductance gradient matrix in shortening the time of the simulation model.
