The waste power battery drive system utilizes a unique form of chain drive that connects the silo. However, due to the large vibration amplitude of the silo during actual operation, it was necessary to establish a three-dimensional model of the automatic feeding mechanism using Solidworks. Through Solidworks/simulation modal analysis, the relationship between the excitation frequency and the natural frequency of the system was analyzed and compared. Furthermore, the model structure was imported into ADAMS for dynamic simulation analysis to study the impact of chain speed, load, and silo number on the system's operational stability. The simulation results indicate that, for this type of low-speed chain drive mechanism, the silo generates periodic excitation to the system through the sprocket. It is important to keep this excitation away from the first-order natural frequency of the system. Moreover, the load quality within the design scope has little impact on the system, and increasing the number of silos can help to enhance the stability of the system's operation. The above conclusions are important for suppressing vibrations in such forms of chain drives.

High altitude areas often lead to more serious corona discharge, and produce more serious electromagnetic environment problems such as audible noise and radio interference, which greatly restrict the selection of transmission lines and cause certain environmental problems. In order to study the characteristics of audible noise in high altitude areas, Yangbajing Town, Lhasa, Tibet Autonomous Region, China (altitude :4320m) and Wuhan city, Hubei, China(altitude :20m). The audible noise characteristics of three different lengths of discharge fine copper wires in high altitude areas (0.8mm, 1.0mm, 1.2mm) were tested. The influence of applied voltage and wire diameter on corona audible noise in plain area and high altitude area is analyzed.

With the emergence of the "double height" features in power systems, the decline of system equivalent inertia has become a serious stability issue. Therefore, virtual inertia control on the power source, energy storage and load side to enhance system equivalent inertia has received widespread attention. Compared to the power source and energy storage sides, the load side has a large adjustable capacity and lower comprehensive cost. Therefore, this paper focuses on loadside virtual inertia control and proposes a time-invariant virtual inertia control strategy for current-source controllable rectifier loads, which solves the potential instability risk caused by time-varying inertia in traditional control methods during multi-machine operation. Finally, detailed simulation results based on PSCAD verify the effectiveness of the proposed control strategy.

The electromagnetic loop network problem of power system is a kind of power network problem that evolves with the development of power grid. In order to avoid the further spread of the problems caused by the electromagnetic ring network, the open-loop operation mode is widely used in the power grid below 500kV to reduce the impact on the power system. In electrified railways, the same phase connection of adjacent traction substations can be achieved through bilateral power supply technology, which increases the terminal voltage level of the traction network. However, an electromagnetic loop network is formed at the 27.5kV traction feeder. The purpose of this paper is to study the generation mechanism of electromagnetic ring network and its influence to power system under bilateral power supply technology. Theoretical support and technical guidance are provided for engineering practice and trial operation.

Remote sensing image classification has experienced three stages: pixel-level, object-level and scene-level. With the improvement of remote sensing image resolution, pixel-level and object-level methods cannot be completely correctly classified, and thus, scene classification is the current focus of this research. We consider the complex background of remote sensing images, the existence of many small objects and the large scale of change, as well as intraclass diversity and interclass similarity. Through the salient regions and features in remote sensing images, a dual attention dense network is proposed. In addition, an adaptive spatial attention module and an adaptive channel attention module are designed. Specifically, the network combines the output of the two proposed attention modules as the feature representation. Among them, the adaptive parameter activation function is introduced into the adaptive spatial attention module, and different nonlinear transformations are performed on the input features in the spatial attention network to achieve attention on important regions. By capturing the adaptive cross channel interaction range to learn channel attention, important weights of each channel are generated and an adaptive parameter activation function is introduced to adjust the feature values of different channels, thereby acting with the global features to achieve attention on the salient features. We present extensive experiments on three scene classification datasets, including the UCM dataset, the AID dataset and the OPTIMAL dataset, and compare them with various algorithms. The experimental results demonstrate the effectiveness of our proposed dual attention model.

Photon counting detector (PCD) is a hot topic at present. Compared with traditional energy integral detector, it has the potential of high spatial resolution, high sensitivity and low dose, which can effectively promote medical imaging diagnosis. However, when PCD is counting X-ray photons, the photon number of each energy bin is relatively small. Additionally, charge-sharing response and pulse superposition effect will also affect the photon count rate, resulting in serious noise and affecting the imaging quality. In this paper, a photon-counting denoising algorithm based on subspace decomposition is proposed. According to the similarity between the data of different bins and the self-similarity of the data, this paper constructs sparse representation by subspace decomposition method and uses block matching algorithm to suppress noise. In simulation experiments, we carried out spectral computed tomography imaging experiments with the three-dimensional phantom of a digital mice based on PCD, and denoised the data by different algorithms. The quantitative results show that our method improves peak signal-to-noise ratio by 2.21dB compared with block-matching and 3D filtering when photon flux is 4×103 , which verifies the potential of the proposed algorithm in medical imaging.
