Green Energy & Environment 2023年第4期8卷 1117-1127页

Hydrogel electrolyte is especially suitable for solid-state Al-air batteries targeted for various portable applications, which may, however, lead to continuous Al corrosion during battery standby. To tackle this issue, an ethanol gel electrolyte is developed for Al-air battery for the first time in this work, by using KOH as solute and polyethylene oxide as gelling agent. The ethanol gel is found to effectively inhibit Al corrosion compared with the water gel counterpart, leading to stable Al storage. When assembled into an Al-air battery, the ethanol gel electrolyte achieves a much improved discharge lifetime and specific capacity, which are 5.3 and 4.1 times of the water gel electrolyte at 0.1 mA cm^(-2), *** studying the gel properties, it is found that a lower ethanol purity can improve the battery power output, but at the price of decreased discharge efficiency. On the contrary, a higher polymer concentration will decrease the power output, but can bring extra benefit to the discharge efficiency. As for the gel thickness, a moderate value of 1 mm is preferred to balance the power output and energy efficiency. Finally, to cater the increasing market of flexible electronics, a flexible Al-air battery is developed by impregnating the ethanol gel into a paper substrate, which can function normally even under serious deformation or damage.

Addressing the issues of blurred details, color distortion, and reduced brightness in hazy images, we propose a dehazing method grounded in model optimization and brightness enhancement. Firstly, the traditional atmospheric scattering model is optimized based on the dark channel prior theory. Second, a luminance augmentation branch is proposed to improve the image brightness. Finally, the images processed by both the model optimization and luminance enhancement branches are fused and subsequently color-corrected to enhance the visual quality of the images. Experimental results on the RESIDE dataset and realworld images show that our method outperforms classical and the latest dehazing methods. © 2025, Politechnica University of Bucharest.

Beamforming prediction based on the multireward DQN framework for UAV-RIS-assisted THz communication systems

作者： Yuewei WU Peng XU Yi LV Dongming WANG Feifei GAO Jiangzhou WANG School of Electronics and Information Engineering Shenyang Aerospace University National Mobile Communications Research Laboratory Southeast University Department of Automation Tsinghua University School of Engineering University of Kent

The terahertz(THz) frequency band offers abundant bandwidth resources but is highly sensitive to obstacles. Attaching a reconfigurable intelligent surface(RIS) to an unmanned aerial vehicle(UAV) to achieve 360-degree panoramic reflection can alleviate blockage [1]. Meanwhile,optimizing the beamforming strategies for the large-scale antenna arrays of the RIS allows for precise coverage of specific areas.

Impacting Mechanism of Variable Leakage Flux on Magnetizing and Demagnetizing Effects in Dual-Variable Flux Memory Machines for EV Traction

引用

IEEE Transactions on Transportation Electrification 2025年第3期11卷 8202-8212页

作者： Zeng, Xianxian Lin, Heyun Yang, Hui Zhong, Yuxiang Zhao, Xifang Liu, Xiping Southeast University School of Electrical Engineering Nanjing210096 China Nanyang Technological University School of Electrical and Electronic Engineering Jurong West 639798 Singapore Jiangxi University of Science and Technology School of Electrical Engineering and Automation Ganzhou341000 China

This article explores the impacting mechanism of variable leakage flux on magnetizing (mag-) and demagnetizing (demag-) effects in dual-variable flux memory machines (D-VFMMs). By reasonably utilizing the variable leakage flux, this kind of machine can achieve higher air-gap flux density by enhancing the mag- effect under high magnetization states (MSs) and lower air-gap flux density by weakening the mag- effect under low MSs. Therefore, an expanded flux regulation (FR) range can be expected without sacrificing torque, which is desired for electric vehicle (EV) traction. The feasibility of regulating the mag- and demag- effects by adjusting the variable leakage flux is first analyzed. The influences of main parameters on the degree of mag- effects are then analyzed in detail. Three topologies are designed to quantitatively investigate the mag- effects by analyzing their electromagnetic properties. Finally, a D-VFMM prototype is manufactured and the impacting mechanism is verified by relevant experiments. © 2015 IEEE.

Dual Perspective Secure Analysis for Local Estimate-Based FDI Attacks in Networked Systems

IEEE Transactions on Systems, Man, and Cybernetics: Systems 2025年第5期55卷 3312-3325页

This article discusses the security concerns related to networked systems, where the sensor sends the local estimate to the remote estimator, which may be attacked. Traditionally, in the remote state estimation with the innovation or raw measurement case, denial of service (DoS) and false data injection (FDI) attacks are investigated thoroughly. Notably, for remote state estimation with local estimate cases considered in this article, most existing works consider DoS attacks but not FDI attacks, negatively affecting remote state estimation performance. Furthermore, current detection mechanisms encounter challenges when identifying such attacks due to the unavailable innovation or raw measurement. As such, we study FDI attacks under this framework and provide the corresponding secure analysis using a dual-perspective approach. Specifically, we propose a detector to detect such attacks using the prior information extracted from the remote estimator. Then, we analyze the existence of stealthy attacks and characterize the corresponding performance evaluation for the remote estimation under such attacks. Following this, we construct the optimal attack scheme, maximizing the expected average and terminal estimation error covariances, respectively. To reduce the above vulnerability, we develop a co-design transmission strategy and offer an analytical detection performance evaluation under different attack scenarios. Finally, simulations are provided to illustrate the proposed results. © 2025 IEEE.

State and parameter identification of linearized water wave equation via adjoint method

In this paper, we focus on the state and parameter identification problem of a hydrodynamical system. This system is modeled as a linearized water wave equation(LWWE), a hyperbolic state-space model coupled with a Laplace equation. We assume that the wave elevation at two distinct points is the only measurement of water waves. We show that the state and water depth can be reconstructed from this point measurement records. The identification problem is recast as an optimization problem over an infinite-dimensional space. We propose the adjoint method-based identification algorithm to generate an estimated state and water depth. We then performed a numerical simulation to show the effectiveness of our designed algorithm by comparing it with existing studies.
