The underwater radiated noise of ships contains a lot of information, which is mainly divided into two signal forms: transient state and steady state. At present, the research technology for steady-state signals has been very mature, but the research on transient signals has always been the focus and difficulty. Therefore, how to obtain the instantaneous characteristics of ship underwater acoustic is an urgent problem in signal acquisition and processing. From the perspective of engineering research, this paper focuses on the analysis of multiple transient signal feature extraction

With the development of the country in information technology, and those technology products are also used in life. Such as capacitive devices in power systems. But capacitive equipment will also have some failures, so it is necessary to monitor it online. Now researchers have found a lot of online monitoring methods, but in most of the current monitoring methods, the monitoring process will produce a huge amount of data, which is very large, so that technicians may miss some important data. In order to solve this problem which can not be discovered early because of the excessive amount of data, this paper adopts some methods based on big data to dig through the data the data obtained by the dig algorithm are statistically analyzed in big data technology. Using the data collected in this paper, through the analysis and research of these data, the results show that the application of big data technology to the on-line monitoring of capacitive equipment is very accurate and practical.

Aiming at the fault of carbon deposition in spark plug of a certain aircraft engine, the sand blasting cleaning technology was proposed. The sand blasting to remove the carbon deposition in spark plug was carried out and the test results were analyzed. The test results show that the surface color of the spark plug after sandblasting is changed from black gray to bright gray, the resistance value of the central electrode was reduced by 120 and 134Ω, and the central electrode is converted from non-conductive to conductive. At the same time, the roughness of the central electrode and the surrounding metal shell after sandblasting is greater than that before sandblasting, and the surface after sandblasting was coarsened. This technology can remove the carbon in the spark cold surface area, and it can provide a good method for removing the carbon deposition in the engine spark plug.

But past skills should also be passed on, some of which contain thousands of years of Chinese spiritual civilization, such as gardens. Therefore, we should make further improvements to the past skills to adapt to the present era, rather than abandoned under the wheels of history to become the past, so the purpose of this article is to use the current front-end virtual reality technology for landscape design to build a new 3Dlandscape design the system. Therefore, after reviewing the development and application level of virtual technology, we construct a new 3D landscape design system on virtual reality technology by using the existing points on the market about the construction of drawing system and classical landscape construction.

With the development of the Internet, intelligence has become an indispensable part, especially in e-commerce, education, and medical treatment. The intelligent sports prediction system came into being. At present, most schools in our country have not established a scientific, reasonable, practical and effective intelligent sports forecasting analysis system for students. So it needs to be studied. This paper mainly uses comparative and experimental methods to compare and analyze the relative advantages of data fusion algorithms and the capabilities of different algorithms in data processing. It is concluded that the system designed in this paper has a higher accuracy of applying SVM algorithm, which can reach 87.25. Although the other methods take a shorter time, their accuracy is not as high as that of SVM.

The digital campus system is based on a computer network and can collect and process existing information to achieve the purpose of modernization of school education, teaching and management. The genetic algorithm does not need to establish a mathematical model and input a large amount of auxiliary information when it is optimized to solve the problem, and it can manage the school well. For this reason, this paper studies and improves the application of genetic algorithm in the design of digital campus system to improve the accuracy of the system. This article mainly uses the experimental method and statistical method to summarize and sort the data formed by the system test, and provide a feasible scheme for the design of the digital campus system. Experimental research shows that the accuracy of the system can reach more than 90% after applying the improved genetic algorithm, which is a design that meets the requirements of the system.
