Escalator is an essential large-scale public transportation equipment. Once the failure occurs, it will inevitably affect the operation and even cause safety accidents. As an important part of the structure of escalator, the loosening of the anchor bolt will lead to abnormal operation of escalator. Aiming at the current difficultyin extracting the fault features of anchor bolt loosening, a fault feature extraction method of escalator anchor loosening is constructed based on empirical wavelet transform (EWT) and bispectrum analysis. First, perform EWT decomposition of the original footing vibration acceleration signal to obtain a series of empirical mode functions(EMFs).Then, for each empirical mode function, the bispectrum was calculated by using bispectrum analysis method, and six texture features of the bispectrum were extracted as fault feature vectors by means of gray-gradient co-occurrence matrix. Finally, the extracted multi-scale fault feature vectors and bi-directional longshort-term memory (BI-LSTM) were used to classify and identify the four types of fault signals with different degrees of foot loosening, and the fault types of foot loosening were determined. The results show that the feature extraction method based on empirical wavelet decomposition and bispectrum analysis can more effectively identify the loosening level of anchor bolts.

The Sino-US trade friction since 2018 is an important turning point in trade relations between these two countries. As the world's two major manufacturing powers, the friction will have a profound impact on the world. This articlesorts out the comparison of economic and trade strength between these two countries in the past ten years, the dependence of import and export, and the changes in trade structure. Then we construct a dynamic evolutionary model of the strategic choices of these two countries in trade friction from the perspective of evolutionary game. Finally, we analyze the stability of the equilibrium point of the evolutionary game by copying the dynamic equation. The results show that when at least one of these two countries has a cooperative benefit less than the speculative benefits brought about by competition, (competition,competition) is the only evolutionary stable strategy combination, andboth of them will adopt competitive measures. The prerequisite for the combination of (cooperation, cooperation) strategies adopted by these two countries are that the net benefits obtained by the two countries' cooperation strategies are greater than the speculative benefits obtained when one side chooses to cooperate and the other side adopts competitive strategy. The probability that two countries choose cooperation strategy is directly proportional to benefits brought about by cooperation and inversely proportional to the cost of cooperation, the loss of sticking to the cooperation strategy, and the speculative benefits of abandoning cooperation. The trade policies of these two countries cannot be achieved overnight, but can gradually tend to be stable and balanced through mutual imitation and learning.

In order to reduce the missed detection error and the systematic error caused by acoustic resonance fluid level detection, liquid level estimation method based on evidence fusion mechanism is designed. It establishes a two dimensional dynamic system model of the standingwavelength. The state evidence of wavelength is obtained through the random set description of evidence, and the extension principle of random set is used to get the observation evidence ofwavelength. The evidential reasoning (ER) rule and dependent evidence fusion are used to fuse those evidence, and the estimation value of fluid level can be calculated from fused result based on pignistic expectation. The corresponding liquid level estimation experiment illustrates the validity and feasibilityof the proposed method.

In recent years, wireless sensor networks (WSNs) have found numerousapplications in industrial manufacturing and people’s daily lives. However, security risks associated with the use of WSNs have also become increasingly pronounced. An attacker launching an internal attack on a WSNmust first physically capture several nodes, i.e., take control of the target nodes by acquiring, cracking, and analyzing important information carried by the target nodes, thus laying the groundwork for subsequent attack steps. Therefore, physical node capture is a critical step in an internal attack on aWSN. Detecting behaviorsthat indicatephysical capture of nodes provides an early warning of anetwork attack, allowing steps to be taken to prevent further attacks from being launched from the captured nodes. This paper proposes an RNN (recurrent neural network)-based detection method that can be used to detect node capture in WSNs with asynchronous sleep mode at an early stage (i.e., before captured nodes rejoin the network).Thus, the methodenables early detection of network attacks. During the decision-making process, a common monitoring mechanism that relies on cooperation between neighboring nodes is employed to improve detection accuracy. The proposed method obtains the sensor nodes’ states and makes a judgment with the help of RNN, achieving accurate detection of node capture under the condition of unsynchronized clocks. Simulation results demonstrate the proposed method’s capability to achieve high detection accuracy.

The new urbanization has a connotation of human-centered urbanization, covering the synchronization of informatization, industrialization, agricultural modernization and urbanization, the optimization of layout, ecological civilization, cultural inheritance, and the realization of balanced and sustainable development among population, economy, society, resources and environment. Taking the path of new urbanization is the development direction of Chinese cities in the future.It is an important measure taken by the Chinese government to implement the new concept of development to promote the optimization and upgrading of the industrial structure and achieve balanced development between ecological and ecological protection and economic and social development. In this paper, firstly, based on the relevant theories of urbanization at home and abroad, the evaluation index system of urban sustainable development is constructed in five dimensions: economic market driving force, population and social development force, resources and environment carrying capacity, public service guarantee force, and urban-rural integration and aggregation force to study the cities and counties in the Beibu Gulf urban agglomeration region. Then, the factor analysis method is used to perform sub-item and comprehensive evaluation on the urban sustainable development capability. Finally, combined with the development characteristics of each city in the urban agglomeration, relevant development strategies and suggestions are put forward to provide reference for the development of urbanization.

Moving target detection is difficult for synthetic aperture radar (SAR). As SAR is designed for imaging of stationary ground scene, the moving targets would be blurred and displaced in conventional SAR imaging. To increase the signal clutter ratio, the moving targets should be refocused while detecting. Based on relative range equation, one can refocus and detect the moving targets simultaneously by searching the relative velocity. This method has been derived and applied for side looking SAR. In this paper, we extend the relative range equation to squint mode. The procedures of the refocusing method are also illustrated. By introducing a parameter of relative squint angle, the imaging position of the moving target is derived. The refocusing method is validated by simulations. The moving target can be optimally refocused, and the refocused position can be parametrized by the relative motion parameters.
