Authors: Liao Maoqiao , Zhang Tiechun , Si Xiaoliang 
Published: October 2024

Abstract
In this paper, according to the terminal vibration test method in SAE-AS5692, a ground fault arc test platform was designed to simulate aircraft vibration-induced ground fault arcs in wiring harnesses and fuel lines, and tandem ground fault arc damage tests were carried out under different conditions and parameters, to study the effects of different power supply types and vibration frequencies on arc damage. The results show that: 1) compared with the arc generated by DC 28 V and AC 115 V, the arc generated by DC 28 V is more damaging to the fuel pipeline, and the pipeline vaporization is more serious; 2) as the vibration frequency is increased from 15 Hz to 60 Hz, the duration of the arc is prolonged, and the arc energy is increased, resulting in a positive correlation between the arc damage and the vibration frequency.

Published: October 2024

Abstract
Wind power has become the focus of new energy generation by its abundant resources and clean and environmentally friendly features. However, as the proportion of wind power connected to the grid rises, there is a risk of causing sub-synchronous oscillation. For the problem of sub-synchronous oscillation, an additional damping control strategy taking into account the rotor side converter of the wind turbine was proposed. This paper establishes the wind power grid connection model, including wind turbine, MMC, and transmission line, and analyzes the generation mechanism of sub-synchronous oscillation using the impedance modeling method. The simulation test was carried out by MATLAB/Simulink. The results show that the control strategy can suppress the oscillation faster, improve the power quality better, and verify the correctness of the method.

Abstract
A PWM method was suggested to eliminate inrush currents in SMPS circuits by digitally controlling the voltage rise rate of the input capacitor. Once the capacitor voltage is fully charged, a bypass switch maintains high conversion efficiency. This PWM-SMPS, tested considering PVT variations, reduces inrush currents by 6× compared to conventional methods with passive components, thus enhancing environmental suitability for SMPS applications.

Authors: Chai Xiaoliang , Zhang Yuanbo , Du Dongyang , Sun Yue 
Published: October 2024

Abstract
To mitigate the adverse effects of uncoordinated charging of electric vehicles (EVs) on the distribution network (DN) stability, this paper proposes a bi-level cooperative optimization scheduling method for EVs and DNs, considering demand response (DR) and carbon quotas. Firstly, EVs are considered flexible resources, and real-time electricity prices are used to guide electric vehicle users to respond to demand, reducing net load fluctuations of DN. Secondly, a carbon quota incentive mechanism based on carbon pricing is introduced, and a dual incentive mechanism of DR and carbon quota is explored to reduce the peak valley load difference further. Then, aiming to minimize the operating cost of the upper-layer EVs and the network loss of the lower-layer DN, a dual-layer cooperative optimization scheduling model for EVs and DNs is constructed, and an improved Particle Swarm Optimization (PSO)-Simulated Annealing (SA) algorithm is used to solve the dual-layer coordination optimization problem. Finally, through case study analysis, the model proposed in this paper demonstrates a 6.32% increase in renewable energy utilization, a 23.75% reduction in carbon emissions, and a significantly reduced network loss.

Published: October 2024

Abstract
At present, the controlled-source audio-frequency magnetotellurics (CSAMT) adopts the traditional tensor measurement with the problems of fragmented detection area and weak signal strength in the far area. In order to realize the 360° omnidirectional tensor measurement of CSAMT, enhance the signal-to-noise ratio of the detection in the far area, and improve the usability of CSAMT under the interference of stronger electromagnetic signals, this paper puts forward a square artifactual source, which is firstly analyzed by the vector synthesis method to realize 360° omnidirectional tensor measurement and simulation verification is carried out. Then, the finite element software COMSOL Multiphysics 6.1 is used to establish the 3D CSAMT model of the square artificial field source and the 3D CSAMT model of the traditional cross-shaped artificial field source, respectively. Through the simulation results of the two types of sources, the signal strengths of the two sources in the far-field region are compared and analyzed, and it is found that the signal strengths of the square field source are improved by about 3.6 times compared with that of the cross-shaped field source in the same position.

Published: October 2024

Abstract
Space charge retention occurs in DC transmission systems during Crosslinked polyethylene (XLPE) cable operation, which causes electric field distortion and insulation failure. For promoting the operation performance of XLPE cable, this paper builds the space charge test system, tests the steady-state space charge distribution of XPLE material at high and low levels in a single period of DC superimposed square wave electric field, and explores the dynamic behavior changes of space charge at the edge time after changing the pressurization time. The reason and macroscopic behavior of the variation of space charge in materials are analyzed from the mechanical point of view. The experimental results show that when the electric field intensity reaches a certain value, the polar space charge will accumulate at the junction of the two poles and the dielectric. The variation of heteropolar space charge is contrary to the absolute value of applied voltage amplitude before and after the edge time. When the edge time increases, the variation of the peak value of space charge at the interface decreases, and the short edge time is more likely to cause microstructure damage. This paper provides direction for explaining the mechanism of electrical branch initiation of XLPE materials.
Cellular mobile station positioning algorithm based on IRS
Authors: Yan Yuqi , Deng Ping 
Published: October 2024

Abstract
Aiming at the problem of positioning performance degradation in complex ground environments due to the Non-Line-of-Sight (NLoS) propagation of cellular uplink signals, in this paper, a cellular mobile station (MS) positioning algorithm based on Intelligent Reflecting Surfaces (IRS) is proposed. First of all, the angle domain method is used to obtain the Angle of Arrival (AoA) information between the MS and each IRS, taking advantage of the emerging IRS technology. Then, based on the position information of each IRS and the AoA measurements, the position of MS can be estimated. In a heavy NLoS environment, when the number of IRS exceeds four, the estimated position mentioned above can be used as the initial position to make position refinement. Based on the known IRS position, base station position, and Time of Arrival measurements from MS to the base station through different paths of IRS, the distances from the MS to each IRS can be estimated. Each IRS can be considered as a Virtual Base Station (VBS) to make this position refinement, and a Time Difference of Arrival (TDoA) positioning algorithm based on iterative Least Squares Estimation (LSE) is proposed to refine the position of the MS. Simulation results show that utilizing the TDoA positioning algorithm proposed in this paper in a heavy NLoS environment, the average positioning error could be reduced to about 0.24 meters compared with only using the AoA positioning algorithm.

Authors: Zhang Jiangcheng , Li Hao , Zhang Zhaolin , Ge Lili 
Published: October 2024

Abstract
In response to the requirements of a satellite micro-vibration testing method, a multi-channel synchronous data acquisition system was designed based on FPGA. The system adopts a modular design philosophy, allowing flexible configuration of the number of acquisition channels by modifying program parameters and reconstructing hardware resources. Signal sampling is performed using high-precision Σ-Δ type ADCs with synchronization capabilities. The synchronization signals for each ADC and the clock signal for filters are uniformly generated by the FPGA, achieving mutual synchronization of multiple sampling channels. LVDS is chosen as the data interface to meet the bandwidth requirements. The host computer communicates with the hardware through the RS232 interface, sending control commands and retrieving LVDS-transmitted data through USB via an interface conversion circuit. The acquired data is displayed in real-time on the user interface in a graphical format. Test results indicate that the system successfully achieves the synchronous acquisition of analog voltage signals across multiple channels, making it suitable for the development of space payload equipment and ground testing devices.
Control strategy of distributed flexible distribution network based on hierarchical optimal control
Authors: Song Zihong , Zheng Youzhuo , Yang Yekui , Wang Xuexue , Guo Dao 
Published: October 2024

Abstract
In traditional hierarchical control strategies, droop control is employed to simulate the behavior of power system generators, modifying the distributed generation (DG) output in relation to frequency and voltage adjustments. However, this control strategy has a single control mode, with all DG operating at the same voltage level, which cannot achieve the economic mode of prioritizing renewable energy supply. Moreover, the adoption of traditional droop control leads to poor current sharing and is not conducive to system stability. This invention introduces a hierarchical optimization control strategy, building upon the traditional hierarchical control strategy. Its characteristics lie in two aspects. Firstly, the hierarchical control strategy is combined with the DC bus signaling (DBS) control strategy, using the bus voltage to reflect the operating state and switch working modes, thereby achieving the optimization control goal of prioritizing renewable energy generation. Secondly, by compensating for the bus voltage and reducing bus voltage fluctuations, the system circulating current is suppressed, and operational stability is enhanced through a PI controller that uses the deviation between the output voltage of the converter and the desired bus voltage. Finally, the effectiveness of the proposed strategy is validated through simulation by using the Matlab/Simulink platform.

Published: October 2024

Abstract
Time-sensitive network requires monitoring the network’s operational status in real-time and dynamically changing the network’s traffic scheduling configuration. A method that can timely obtain network operation information is needed. In this paper, a method for proxy hosts to send monitoring packets is proposed, which enables visits and the collection of status information for all switches through a single monitoring packet. Then, it returns the monitoring packet to the CNC controller for processing. To verify this method, the collection of TSN status information in a ring topology is simulated, mainly to obtain the delay of each hop node. The simulation results show that the BE flow is blocking some switches and requires adjustment and load balancing, while the delay of TT flow is relatively stable on all switches. The end-to-end latency difference between BE and TT flows is nearly 20 times. The experiment shows that under the TSN scheduling mechanism, a deterministic delay of TT flow has been achieved.

Published: October 2024

Abstract
The Bandgap reference (BGR), usually referred to as a voltage source with high stability, is an indispensable basic circuit module in digital analog systems such as sensors, serdes, linear voltage regulators (LDO), and switching regulators. This paper put forward a BGR, which is based on the Brokaw structure, with a low-temperature coefficient and high precision. The BGR has the characteristics of fewer components, wide applicability, and an excellent index. At the process corner, in the range of -40-125°C, the temperature coefficient can reach 4.52 ppm/°C, while in the Monte Carlo simulation, the 3σ accuracy is 0.6%. The circuit can work under a wide input voltage of 1.8-3.3 V, which greatly reduces the influence of resistance, bipolar transistor, and op-amp input offset voltage on BGR output.

Published: October 2024

Abstract
Considering the special structure of a wireless power transfer system, there is no direct electrical connection between the sending module and the receive module. To increase the system interoperability, it is necessary to realize the information transfer during power transmission. In this paper, Selected Harmonic Elimination PWM (SHEPWM) is applied to make a single inverter generate two controlled frequency components. During normal power transmission, the proposed WPT system can also realize information without any high-frequency signal sources. For information transmission, an additional coil is applied to build an information transmission channel without a tightly coupled transformer. Besides, the corresponding information modulation and demodulation methods are redesigned. Finally, a simulation case based on this proposed WPT system is carried out. The rate of information transfer is 42.5 kbps.

Published: October 2024

Abstract
This paper proposes improved radar pulse sorting signals by the Density-Peak (DP) algorithm. In this study, we propose finding a density threshold within the entire density interval to distinguish radar pulse signals and noise pulse signals, leading to higher sorting accuracy. Through MATLAB simulations, we compared the performance of the improved DP algorithm with the original Density Peak algorithm, as well as the traditional K-means and FCM algorithms. Our results verify that the proposed DP algorithm outperforms these other methods by sorting accuracy and Adjusted Rand Index (ARI). The accuracy of this work can reach 98.30%, and the ARI of this work can reach 0.9627, which verifies excellent performance.

Abstract
In recent years, the launch and operation of large-scale LEO communication satellites has been a development trend and research hotspot in the field of satellite communication. However, large-scale satellite networking will inevitably lead to the waste of beam and frequency resources, thus reducing the efficiency of the system and increasing the energy consumption of the satellites. In this paper, a beam management strategy based on LEO constellation topology is proposed and simulated by using the Iridium generation constellation system as model input. The simulation results show that the proportion of C/I greater than 16 dB in the global region has increased from 84.57% to 98.89%.

Authors: Liu Kai , He Chuchao , Zhao Xiangmo , Di Ruohai , Li Xiaoyan , Sun Mengyu 
Published: October 2024

Abstract
Nowadays, load cells are widely used. However, the influence of the external environment, the degradation of the sensor performance, and other issues may result in measuring sensor deviation, thus affecting the accuracy of the measurement results. An adapted Kalman filter algorithm calibration algorithm is designed. Firstly, it compares the output of the sensor with the real value to get the observation residual. Secondly, based on the residuals and predefined noise and covariance matrices, the calculation of the gain matrix is performed, and finally, the estimate and matrix are updated. In the updating process, to address the issue of sensor output anomaly, adaptive adjustment of the parameters of the Kalman filter is used. Experiments show that the calibration algorithm based on adaptive Kalman filtering can run well on the embedded platform with good accuracy and stability. After calibration, the accuracy of the sensor is improved from 0.05% F.S to 0.01% F.S.

Towards Defining Climate Adaptation Literacy in the Context of Urban Resilience
Authors: Khoja Ahmed , Felicioni Licia , Danylenko Olena 
Published: October 2024

Abstract
The climate crisis intensifies rapidly, straining the urban environment and society. Addressing climate change requires collaborative efforts, integrating physical resilience with knowledge empowerment. Formal and informal knowledge are vital for effective adaptation. In the updated Intergovernmental Panel on Climate Change (IPCC) AR6 Report an emphasis on knowledge and its role in reducing response risk was highlighted. At the urban scale, adaptation knowledge is essential, bridging social and technical systems. Here, community knowledge evolves from a passive component within a greater adaptation strategy to an active, integral element. This paper develops a unique definition of climate adaptation literacy for the urban built environment based on an extensive literature review on urban climate adaptation, guided by the PISA (Program for International Student Assessment) 2025 Framework. The results of this work highlight existing gaps in climate adaptation knowledge and present urban climate adaptation literacy as a means to measure the response risk. These insights aid the formulation of resilience policies and urban adaptation strategies and contribute to the safety, resilience, sustainability, and functionality of the material and non-material values of the urban environment

Published: October 2024

Abstract
This chapter explains that wavetable synthesis is a category of music synthesis useful for producing realistic sounds. With wavetable synthesis, a table of samples is stored in a memory block and played back at a periodic rate to recreate a sound. The wavetable project is a simple synthesizer that uses two potentiometers to control the attack and release of an envelope. The chapter then discusses how to use potentiometers to interact with the audio system and incorporate USB to process MIDI Note-On and Note-Off messages. It elaborates on how the wavetable object’s output can be processed by other objects in the library, such as filters and digital signal processors.
