Microgrids equipped with hybrid energy storage systems (ESSs) are increasingly critical for balancing the intermittency of renewable energy sources (RESs) and the fluctuations in demand. This paper introduces a novel Multi-Agent Imitation Learning (MAIL) framework for real-time energy management in microgrids, particularly under real-time pricing conditions. The approach leverages a problem decomposition strategy, which separates the energy management task into two phases: first, optimal actions for each ESS are estimated using individual agents, each employing a deep neural network (DNN) trained to emulate an ideal mixed-integer linear programming (MILP) solver;then, a one-step online optimization reacts to these decisions to optimize the remaining system components holistically. Rigorous proofs establish the equivalence of the decomposed subproblems to the original optimization problem, ensuring integrity and effectiveness. Comparative simulation studies with real-world data reveal that our MAIL framework offers significant cost advantages and superior training efficiency relative to both traditional single and emerging multi-agent reinforcement learning (RL) methods. Notably, the operational costs achieved through our approach are markedly lower than those of its counterparts, closely approximating the theoretical minimum. This underscores the method's proficiency and its potential as an effective solution for microgrid energy management. Moreover, the MAIL strategy's multi-agent design allows for straightforward scalability to more extensive systems involving multiple ESSs and shows promising potential for cooperative management across interconnected microgrids. © 2014 IEEE.

Sensing Metal Coil Vibration of Headsets for Eavesdropping on Online Conversations With Out-of-Vocabulary Words Using RFID

IEEE Transactions on Mobile Computing 2025年

作者： Chen, Yunzhong Yu, Jiadi Chen, Yingying Kong, Linghe Zhu, Yanmin Chen, Yichao Shanghai Jiao Tong University Department of Computer Science and Engineering Shanghai China Rutgers University Department of Electrical and Computer Engineering United States

As one of the most essential accessories, headsets have been widely used in common online conversations. The metal coil vibration patterns of headset speakers/microphones have been proven to be highly correlated with the speaker-produced/microphone-received sound. This paper presents an online conversation eavesdropping system, RFSpy, which uses only one RFID tag attached on a headset to alternately sense metal coil vibrations of headset speaker and microphone for eavesdropping on speaker-produced and microphone-received sound. In some accessible scenarios, assuming attackers secretly attach a small, battery-free RFID tag under one ear cushion of an eavesdropped user's headset without being noticed. Meanwhile, RFID readers are camouflaged as decorations placed in/out of rooms to transmit and receive RF signals. When the eavesdropped user talks with other users online through the headset, RFSpy first activates the RFID tag to capture the metal coil vibration patterns of headset speaker and microphone upon RF signals. Then, RFSpy reconstructs sound spectrograms from the RF signal-based vibration patterns for not only trained words but also untrained (i.e., out-of-vocabulary) words utilizing designed SSR network. Finally, RFSpy converts the sound spectrograms to conversation content through sound recognition API. Extensive experiments demonstrate that RFSpy can eavesdrop on online conversations with out-of-vocabulary words effectively. © 2002-2012 IEEE.

The evolution of science and technology has led to increasingly complex cyber security threats, with advanced evasion techniques and encrypted communication channels making attacks harder to detect. While encryption has improved privacy and confidentiality for users, it has also provided a new avenue for attackers to exploit. Traditional intrusion detection systems, which transitioned from signature-based to behavior-based approaches, have struggled to keep up with these challenges. To address this issue, researchers have turned to continuous system monitoring and network traffic packet analysis. However, this method can be resource-intensive and time-consuming, particularly when analyzing encrypted packets. In this study, the JA3 fingerprint infrastructure was examined as a potential solution for quickly detecting attacks conducted over encrypted sessions while minimizing system downtime and damage. The results demonstrated that the JA3 infrastructure effectively detected attacks carried out via encrypted channels. Although Windows 10 and Kali 2020.4 operating systems were used as the victim and attacker systems respectively, the methodology can be applied to other operating systems and network hardware by following the outlined steps. This research is expected to make a significant contribution to the field of encryption-based attack prevention. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

In expressway systems, critical challenges in toll plaza management arise due to traffic congestion at toll plazas during rush hours. Existing studies often rely on prediction models or simulations, where their accuracy to real traffic conditions is compromised. This study proposes a new framework for the service time to improve the overall analysis of lane capacity calculation for toll plaza management. The investigation uses real transaction data from the three expressways with the highest traffic volume from the Expressway Authority of Thailand (EXAT). The preprocessing includes data cleaning and outlier removal, where the interquartile range method is used to eliminate data that are above the range of realistic service time. Afterward, the upper bound threshold and k-nearest neighbors algorithm are used to learn a traffic pattern model to categorize peak and off-peak traffic. Our new framework is investigated both with real transaction data and in simulations. As a result, the lognormal distribution is best suited for describing the service time. It can improve the accuracy of the service time by 80.59% on weekdays and by 72.64% on weekends for the calculation of the lane capacity. This marks a significant improvement in toll plaza management. © 2024 IEEE.

Nowadays, the speed of solving optimization problems by increasing various issues and the number of variables is critical. The Harris Hawk optimization method is a brand-new, intelligent system that resolves optimization issues by mathematically simulating the natural behavior of hawks. In this study, the Harris Hawks optimization method and the Laplace crossover operator are merged, and a new enhanced Harris Hawks algorithm (LX-HHO) based on the Laplace optimization algorithm is suggested. The purpose of improving this algorithm is to increase the convergence speed while maintaining good accuracy in achieving the optimal solution. The results of the proposed method on the test functions demonstrate that the algorithm has achieved faster convergence than the original version of the Harris Hawks algorithm and other meta-heuristic algorithms. This is due to the algorithm's accuracy in obtaining the best answer in these functions and to a reduction in the evaluation of the optimization function. Also, comparing and evaluating the proposed algorithm with other algorithms by Friedman and MAE test shows the superiority of the LX-HHO algorithm. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

This paper presents a systematic literature review conducted to investigate the validity of the adopted methodologies and variable considerations of forecasting renewable energy load requirements. A total of 213 studies from renowned scientific databases, including IEEE, Springer, Elsevier, ACM, and Taylor & Francis, were initially considered, resulting in a final selection of 23 primary studies using the inclusion and exclusion criterion. The review focused on analyzing the internal and external validity threats associated with the methods employed in these studies. Findings revealed several critical gaps in the methodology of the reviewed studies. Studies failed to address the bias-variance tradeoff, which is crucial for ensuring accurate predictions. A significant number of studies ignored parameter optimization in deep learning models, potentially impacting the reliability and precision of the load requirement forecasts. Studies did not conduct tests for multicollinearity of predictive attributes, which may lead to misleading results and inflated model performance. Few studies incorporated environmental and socioeconomic attributes in their datasets, which could have significant implications for energy consumption. Observations from this study highlight the importance of considering these gaps in renewable energy load requirement forecasting to enhance the accuracy and applicability of the resulting models. It emphasizes the significance of properly accounting for bias-variance tradeoffs, optimizing model parameters, and conducting tests for multicollinearity. The inclusion of environmental and socioeconomic variables in training sets is encouraged to capture the intricate relationships between these factors and energy consumption accurately. The study contributes to the improvement of renewable energy load requirement forecasting methodologies by promoting robust practices and considering comprehensive sets of variables. © 2024 IEEE.
