so far, there is a question about the existing study of electromagnetic relay’s life prediction: they mainly focused on the research of batch products as a whole, which cannot reflect individual differences. This paper proposes one kind of way about the life prediction of electromagnetic relay based on Bayesian method. Firstly, a prior distribution of the model parameters is determined on the basis of the determined degradation model. Then, the degradation data (contact resistance) based on the prior distribution is fused, and the parameters of the degenerate trajectory model are updated to obtain the reliability function. Finally, we can predict the lifetime of a single electromagnetic relay. The results show that the lifetime prediction of a single electromagnetic relay is realized by the Bayesian method, in which the No.10 electromagnetic relay predicts the life of the electromagnetic relay to be $1.28 times 10^{5}$ times and the relative error is 0.06 for the test lifetime value is $1.21 times 10^{5}$ times under the condition of a reliability of 90%. The feasibility of predicting the lifetime of a single electromagnetic relay using fusion degradation data is verified

This paper presents a method for checking the status of isolators, which is applied in the sequence control in smart substation based on mobile substation inspection robot (PowerRobot). It can recognize the status of an isolator through analyzing the features. The homography matrix can be obtained by using the SIFT feature between the template image and new acquired image. Then it gets the range of isolator, finally recognizing the status of isolator by image processing. The experiment results prove that the method could recognize the isolator status effectively. The substation realizes one key sequence control system through this technology based substation inspection robot.

To solve the problem that low efficiency and slow convergence speed of traditional attribute reduction algorithm, we propose an attribute reduction algorithm which based on the genetic algorithm and rough sets. To obtain the minimum attribute reduction, attribute dependence and hamming distance as constrains is introduced in population initialization. When the fitness function is designed, the average attribute importance is introduced as the correction factor, and the fitness function is dynamically adjusted. The improved adaptive crossover and mutation probability are adopted, and in the cross-operation, a small-scale competition strategy is used. Experimental results prove the efficiency of the proposed algorithm in attribute reduction for high dimensionality and big data.

In this paper, we propose a novel image segmentation algorithm, Fuzzy-Based Differential Lion Pride optimization (FDLPO). We combine the concept of the Fuzzy C Means (FCM) and an improved Lion Pride optimization (DLPO) with a new crossover strategy which is inspired by Differential Evolution (DE). First, we search for optimum clusters by fuzzy membership function and LPO which has better performance than most of the other algorithms. Then, the crossover mechanism of the differential evolution is used to improve the diversity of offspring and speed up convergence in lion pride optimization. FDLPO becomes more efficient as it overcomes the drawbacks of FCM and LPO which does not depend on the choice of initial cluster centers and it performs better in terms of convergence, time complexity and robustness. The experiments with DLPO, LPO and PSO are executed over some benchmark test functions. Meanwhile, the efficiency of FDLPO is proven by both quantitative and qualitative measures.

With the rapid development of social economy and modern technology, people have shown unprecedented concern about the safety needs of civil aviation travel. The ADS-B system has been gradually adopted by more and more countries in the world because of its high positioning accuracy, fast data update, low cost of building stations, and no low-altitude blind spots. This paper uses the self-developed KZ-SDR-ED software radio development platform to design an ADS-B all-digital software receiver, which receives the broadcast signals of multiple civil aircraft within 100km and follows the message format of ADS-B signals. It is decoded to obtain operational parameters such as speed, altitude, latitude and longitude coordinates of the civil aircraft, and the four-dimensional position and navigation trajectory of the aircraft are displayed in real time through an intuitive GUI interface.

As the information of online music resources continues to grow, it becomes more and more difficult for users to find their favorite music. Accurate and efficient music recommendation is very important. Music recommendation is a research hotspot in the field of speech processing. Calculate the mel frequency cepstral coefficient (MFCC) feature quantity by analyzing the characteristics of music content. Then, the feature quantities are clustered to compress the music feature values. Finally, the distance metric function is used to calculate the similarity between all music in the feature value database of the searched music. The closer the distance is, the higher the similarity is. According to the similarity, we can get the result of recommendation. The method recommended results have higher accuracy in experiments and provides an idea for music recommendations when user data is missing.
