Target controllability is an interesting property of complex network and attracts many researchers from different fields. However, controlling large natural or technological networks is a great challenge. But it is not feasible and sometimes unnecessary to control the entire network, hence target control seems efficient in this situation. The greedy algorithm was developed and offers a good approximation to calculate the minimum number of driver nodes, where control signals are injected, for control the target nodes in the network. Based on the target control theory, we investigate the target controllability of directed Erdős-Rényi and the Barabási-Albert networks under attack or failure. Results show that degree-based node attack is more efficient than random attacks in directed BA networks on network target controllability but the similar in directed ER networks.

The quality of mechanical products depends on the quality of mechanical parts and the assembly quality of products, and the quality of parts is the basis of assembly quality. The quality of mechanical parts is related not only to the performance of materials, but also to the accuracy of machining and the quality of machined surface. The accuracy of machining is an important index to evaluate the quality of parts. Due to various reasons in the process of processing, there will always be some deviation between the actual processed parts and the ideal parts. This deviation is called machining error. Machining accuracy and machining error are actually evaluated from two viewpoints on the same problem of part quality. The high or low machining accuracy can be expressed by the small or large machining error. In actual production, the aim of improving the quality of parts processing is often achieved from the point of view of reducing processing errors.

In order to study the variational mode decomposition (VMD) algorithm for the analysis of acoustic signal characteristics of underwater plasma sound source pulse discharge, a simulation model of central control module is established by using VMD algorithm. The whole hardware circuit takes the FPGA (Field Programmable Gate Array) chip as the intelligent control center of the central control module, and combining with the minimum composed of basic power supply circuit, clock circuit, reset circuit and configuration circuit, the model is used to analyze the characteristics of acoustic signals. The results show that the uncertainties of these parameters also affect the performance of VMD. In VMD decomposition, the smaller the equilibrium constraint parameters are, the larger the bandwidth of each modal component is, the more likely the phenomenon of center frequency overlap and mode aliasing will occur. The larger the equilibrium constraint parameters are, the smaller the bandwidth of each component signal will be, and the phenomenon of center frequency overlap and mode aliasing will disappear. Through analysis, it is proposed that the general equilibrium constraint parameters can be taken as sampling frequency fs in practice. The acoustic signal of VMD applied to underwater plasma sound source pulse discharge is analyzed, and the results are as expected. It provides a theoretical basis and practical basis for its application in underwater plasma acoustic signal characteristics analysis. This is of great significance to the study of VMD as an underwater plasma source for the analysis of acoustic signal characteristics of pulse discharge.

Smart grid, as the next generation of power grid characterized by “two-way” communication, has been paid great attention to realizing reliable and flexible electricity delivery for our future lives. In order to support the two-way communication in smart grid, a large number of smart meters (SMs) should be deployed for customers to report their real-time data to control center. However, this kind of real-time report would disclose users’ privacy, bring down the users’ willingness to participate in smart grid. In order to address this problem, in this paper, we propose a groupingbased aggregation protocol with error tolerance for privacy-preservation in smart grid (GBAP-ETPP), which employs the counting bloom filter to save storage space and improve the query efficiency. We also solve the false positive of bloom filter by choosing appropriate IDs in the system setup. In addition, we group users and all users in the same group share the same key. Thus, we can normally run our algorithm by substitution even there are some malfunctioning SMs. Detailed security analysis and theoretical proof show that our scheme can guarantee the security and privacy requirements of all the users in the smart grid.
