Aiming at the low prediction accuracy of current lithium-ion battery cycle, this paper proposes a model based on differential evolution algorithm (DE) and BP neural network fusion. BP neural network is used to predict the cycle life of lithium-ion battery. The DE algorithm is used to optimize the initial weight and threshold of BP neural network, which reduces the number of iterations of neural network and accelerates the convergence speed. The prediction results show that the prediction model has higher prediction accuracy, effectively improves the convergence speed of BP neural network, and meets the characteristics of battery operation, which is of great significance for improving the timeliness and accuracy of battery life assessment.

The advent of the internet of things and big data era has brought new ideas for corrosion analysis and prediction of refining units. With the establishment and application of all kinds of information systems, refining enterprises have accumulated a large number of structured, unstructured, corrosion influencing factors and corrosion result data sources, but all kinds of system data are independent, and the traditional storage methods are limited in calculation, processing and analysis and mining ability, which do not have the conditions of big data analysis and utilization, so it is urgent to study the standardized collection method of corrosion data and establish a unified data center. Based on the whole life process of equipment, this paper studies the data content, data characteristics and current main data acquisition and management forms of corrosion related data in each link of the equipment through-life. In addition, this paper puts forward the overall structure of corrosion big data standard acquisition system for refining process in the enterprise as a whole. The big data acquisition system, which is suitable for corrosion big data comprehensive collection, efficient storage and open interface, is established to carry on the data acquisition step by step, and lays a foundation for the acquisition and analysis and utilization of corrosion big data from refining process.

A The combat command and control system is the nerve center to carry out joint operations. It is an important part of military operations in the information age and plays the role of "amplification multiplier" in the enemy operations. In this paper, a combat command network system was taken as the research object, and the reliability modeling and analysis of the combat command network were conducted based on dynamic Bayes-GO method. Firstly, the mapping rules for transforming common operators, type 18A and type 20 operators in GO method into dynamic Bayesian networks are given. Then, the task of the brigade command vehicle 2 commanding the combat vehicle 5 to strike the target in a combat command network was modeled and analyzed. Finally, the dynamic availability curve of the system within t = 300h and the availability corresponding to the system at each moment are calculated, which can enable the combat commander to clearly judge the reliability of the system in successfully hitting the target at each moment, thus the other combat equipment can be better dispatched for cooperative operations.

An efficient reliability design optimization method based on information reconstruction Kriging model is developed to further improve the computational efficiency. Inspired by the concept of incremental shifting vector, the conventional nested double-level optimization can be decomposed into updated deterministic optimizations and reliability analysis subproblems, which can simplify the reliability design optimization problem. The history iteration information of the reliability analysis is used to reconstruct the Kriging model and the active Kriging method is employed to address the reliability analysis problems efficiently. The most probable points (MPP) and its gradients of the current iteration process for the reliability constraints are obtained approximately to update the deterministic optimizations. Two numerical examples are investigated to demonstrate the effectiveness and efficiency of the proposed method. It is shown that the proposed method can improve the calculation efficiency while satisfying precision. And the method has the characteristics of high precision and moderate calculation when dealing with nonlinear problems.

Considering the diesel engine vibration signals have the characteristics of the non-stability and non-linearity due to its compact-complex structure, strong noise and especially unstable operating conditions, we proposes an novel method based on improved wavelet packet-Mel frequency and convolutional neural network (CNN) to extract features and diagnose faults of diesel engine valve. Firstly, the wavelet packet transform is applied with the purpose of decomposing vibration signal and reconstructing each wavelet packet coefficient. Secondly, an improved Mel frequency cepstrum method is used to extract features from the reconstructed vibration signals. MFC algorithm is a well-known feature extraction technique widely used for speech recognition. Then, feature matrixes are constituted to obtain more definite and comprehensive time-frequency distributed representation, of which the row represents the average Mel frequency cepstrum coefficients and the column represents the frequency bands of wavelet packet decomposition in ascending order. Finally, a deep hierarchical CNN structure constructed by convolution layers, max-pooling layers and fully-connected layers is trained using a standard backpropagation, of which the input of first layer with 256 neurons is the above 2D feature matrixes and the output of final layer with 3 neurons is the number of vibration signal states. The experimental results of the fault diagnosis for the diesel engine valves show that the proposed method has the good diagnosis performance for diesel engine valve clearance faults.

To address the problems of the details blurring and color distortion existing in the multi-angle underwater polarized images, the paper proposes a restoration algorithm of underwater polarized images based on DCP(dark channel prior), which combines the characteristics of underwater polarized images with the DCP. Firstly, the transmittance and the object reflected light with polarization characteristics of two Orthogonal polarized images are calculated by the improved DCP. Then, the polarization components existing in the object reflected lights are eliminated by the global polarization angle to obtain the original object radiance. Finally, the color correction is carried out by gray world algorithm to get the final restoration result. The proposed method is mainly designed to solve the problems of the limited utility of DCP in the deblurring of single underwater image and the noise caused by conventional polarized restoration methods. The experimental results show that the proposed method can make the details of images more obvious and significantly improve the clarity, contrast and the color distribution of underwater polarized images.

To address the problems of high incidence of faults in tank autoloaders, long diagnosis cycle and low accuracy of diagnosis, this paper proposed a perceptive fuzzy Petri net-based fault diagnosis method on the basis of relevant expertise. The corresponding NFPN failure model was established according to the specific structure of the autoloader, fuzzy Petri net was used to present the process of fault propagation, the perceptron error back propagation method was adopted to learn the limited expertise, and the values of arc weights of trigger accidents in the Petri net were determined. An accurate judgment on autoloader faults was achieved by way of forwarding reasoning. At the time of backward reasoning, the minimal cut set method was also adopted to narrow the troubleshooting scope, thus improving the reasoning efficiency. By taking an autoloader with a rotary failure as an example, this paper established the corresponding PFPN fault model and made a comparison with the fault tree seasoning method and the historical statistic data. The comparison results reveal that this method can realize a quick and high-efficiency fault diagnosis of autoloaders thanks to its higher reliability and accuracy compared with the traditional fault tree diagnosis method.

The present study is centered around the micro actuator, which uses the microelectromechanical system (MEMS) technology in the safety and arming (S & A) device for the fuze. In a complex fuze system, we propose a design optimization scheme for arming based on the conventional disc-type micro electromagnetic actuator. The working principle of this S &A device is first introduced in brief. Then theoretical numerical calculation is performed and finite element simulation software is used for simulation. It is found that as compared with the conventional micro electromagnetic actuator, the electromagnetic force required by the lock pin of this new actuator during unlocking of the lock pin decreases by 41%. Thus the jamming problem of lock pin during the working process of the micro electromagnetic actuator is well solved. This S&A mechanism enhances the reliability of fuze. The present study lays the basis for the design of a micro electromagnetic actuator used in MEMS.
