The growing demand for reliable and sustainable energy has driven researchers and engineers to explore renewable energy sources to complement traditional power grids. Wind energy conversion systems (WECS), particularly those using permanent magnet synchronous generators (PMSG), are among the most widely adopted renewable energy solutions. Integrating WECS into traditional grids introduces challenges, including power system oscillations, especially during disturbances or faults. Inertia control and power electronics converters are pivotal in mitigating these oscillations and ensuring grid stability. This review investigates the design and optimization of damping controllers, emphasizing their integration with excitation systems to enhance the dynamic performance of PMSG-based wind integrated grids. Additionally, the role of power electronics in control strategies and inertia emulation for stable grid operation is discussed. The findings highlight the critical importance of advanced control measures in addressing the inherent uncertainties of renewable energy systems integrated with conventional grids. © 2025 IEEE.

Underwater wireless sensor networks can monitor ocean information, which provides a new approach to marine environmental monitoring, disaster warning and resource exploration. However, the development of underwater wireless sensing networks is limited by factors such as ocean currents and limited energy of the sensors themselves. Based on this situation, this paper proposes a transmission scheme based on collaborative communication with autonomous underwater vehicles (AUVs), in which autonomous underwater vehicles (AUVs) are used as a tool for distributed data collection and forwarding, which can solve the problem of imbalanced energy consumption of sensor nodes in the traditional multi-hop underwater communication network. At the same time, we consider the influence of ocean currents on the node positions to maximize the imitation of the real underwater environment, and the simulation results show that the proposed transmission scheme for collaborative communication with AUVs can significantly prolong the service life of underwater sensor networks. © 2025 SPIE.

In today's software testing community, quality assessment remains critical, with mutation testing standing as a cornerstone technique for evaluating the effectiveness of test cases. This method involves introducing faulty code, or mutants, into the program to assess the quality of the test suite and other testing methods. However, mutation testing faces challenges such as the generation of numerous mutants, the presence of equivalent mutants that are difficult to detect through testing, and the lack of realistic mutant creation. Literature reviews indicate significant efforts to address these issues through formal solutions and heuristic methods. Recent optimization-based methods are now recognized as cost-effective result in an optimized solution. Hence, to overcome these limitations, this study introduces SQUMUTH, a novel approach for high-order mutant generation based on the Squirrel Search Algorithm (SSA). Inspired by the foraging behavior of squirrels, SSA offers a promising solution for enhancing the efficiency and effectiveness of mutation testing. Experimental evaluations on eight well-known Java benchmark programs demonstrate that SQUMUTH outperforms existing methods. Comparative analyses of mutation scores and the rates of realistic mutants consistently show its better performance across all subject programs compared to other state-of-the-art methods such as Social Group Optimization, Binary Genetic Algorithm, and random testing. The experimental results underscore its effectiveness in generating more realistic mutants. The experimental results indicated that the proposed approach has the potential to advance software testing by improving the cost-effectiveness of mutation analysis and the quality of software systems. © The Author(s) 2025.

It has been observed that individuals prefer to favour information that strengthens their beliefs or values, while information that contradicts them causes unpleasant feelings and is more likely to be ignored. This is known as confirmation bias, and it is usually difficult to dislodge once affirmed. Confirmation bias has been shown to lead to flawed decisions in political, organizational, financial and scientific domains. To better understand the origins and detection of neural biomarkers for confirmation bias, this article presents a study that employed electroencephalography (EEG) signals from 10 participants. The study revealed an apparent increase in theta activity (phase-resetting) and prediction error negativity (PEN) among participants exhibiting confirmation bias. These findings have the potential to contribute to the development of novel brain-computer interface systems capable of detecting confirmation bias. Such systems may help mitigate social polarization and the negative effects of biased decision-making. © 2025 IEEE.

A New Benchmark and Algorithm for Clothes-Changing Video Person Re-Identification

引用

IEEE Transactions on Information Forensics and Security 2025年 20卷 1993-2005页

作者： Wang, Likai Zhang, Xiangqun Han, Ruize Wei, Yanjie Wang, Song Feng, Wei Tianjin University College of Intelligence and Computing Tianjin300350 China Shenzhen University of Advanced Technology Faculty of Computer Science and Control Engineering Shenzhen518107 China Shenzhen Institute of Advanced Technology Chinese Academy of Sciences Shenzhen518055 China

Person re-identification (Re-ID) is a classical computer vision task and has significant applications for public security and information forensics. Recently, long-term Re-ID with clothes-changing has attracted increasing attention. However, existing methods mainly focus on image-based setting, where richer temporal information is overlooked. In this paper, we focus on the relatively new yet practical problem of Clothes-Changing Video-based Re-ID (CCVReID), which is less studied. First, given the dataset shortage, we build two new benchmark datasets for CCVReID problem, including a large-scale synthetic video dataset and a real-world one, both containing human sequences with various clothing changes. Moreover, we systematically study this problem by simultaneously considering the classical appearance feature and temporal feature contained in the video. We develop a dual-branch fusion framework that makes use of the information from both clothes-aware appearance feature and clothes-free gait feature. For better information fusion, a confidence-guided re-ranking strategy is proposed to adaptively balance the weight of these two categories of features. We have released the benchmark and code proposed in this work to the public at https://***/kkw98/CCVReID. © 2025 IEEE.

A Note on the Local Observability of Uniform Hypergraphs

A Note on the Local Observability of Uniform Hypergraphs

引用

94th Annual Meeting of the International Association of Applied Mathematics and Mechanics, GAMM 2024

作者： Gerbet, Daniel Röbenack, Klaus Institute of Control Theory Faculty of Electrical and Computer Engineering TUD Dresden University of Technology Dresden Germany

Hypergraphs generalize graphs in such a way that edges may connect any number of nodes. If all edges are adjacent to the same number of nodes, the hypergraph is called uniform. Thus, a graph is a 2-uniform hypergraph. Each uniform hypergraph can be identified with an autonomous dynamical state-space system, whose vector field is composed of homogenous polynomials. We consider the observability of dynamical systems, which possess this special structure. In control theory, the observability of a dynamical system asks for the possibility to reconstruct the systems state from an output trajectory, where the output is a projective measurement of the systems state. In addition, one can ask for the observable subspace of the state. Nonlinear systems, although observable at almost all points in the state space, may possess not-locally observable ones. The existence and location of such states are important for observability analysis and observer design. Recently, the observability of these hypergraph systems has been studied for the general case. We apply an extended deterministic observability test to uniform hypergraphs and also compute the not-observable states for different linear output maps. We are able to confirm the results of the recent study, at least for graphs with a small number of nodes, due to the computational complexity of our method. In addition, the not-locally observable states are computed for different combinations of measured nodes. © 2025 The Author(s).

Enhancing Power Density in Switched Reluctance Generators Through Split Axial Segmentation

引用

IEEE Access 2025年 13卷 70055-70079页

作者： Siagian, Parlin Sara, Ira Devi Tarmizi, Tarmizi Nasaruddin, Nasaruddin Universitas Syiah Kuala School of Engineering Banda Aceh23111 Indonesia Universitas Pembangunan Panca Budi Sains and Technology Faculty Medan20122 Indonesia Universitas Syiah Kuala Department of Electrical and Computer Engineering Banda Aceh23111 Indonesia

The main contribution of this paper is to propose a methodology for the electromagnetic design of split axial segmentation switched reluctance generators (SRGs) to optimize power and torque. This paper investigates the impact of generator geometry segmentation on performance, addressing the longstanding challenges of torque ripple and power density. The hypothesis suggests that dividing the stator magnetization at each rotor angle can counteract the opposing machine torque, thereby improving torque ripple and enhancing power density. A mixed-methods approach combining literature review, simulation, and experimental validation was used to evaluate torque retarding effects and machine power density. The results demonstrate a significant reduction in torque ripple (59.3%) and an increase in power density 603.3kW/m3 across all four segments. Specifically, axial separation segmentation markedly enhanced power density and design efficiency compared to conventional SRGs designs. This paper provides novel insights into improving torque ripple and power output while maintaining the same overall machine dimensions at 1206.6 W. Additionally, the simpler fabrication process of axial segmentation—where each segment maintains the same diameter—offers distinct advantages over radial segmentation, making it more practical for manufacturing. These findings highlight the potential for harvesting low-power driving energy from natural sources, contributing to advancing renewable energy technologies. So, the improvements in torque ripple reduction and power density provide valuable directions for optimizing SRGs, with further potential for enhancing driving turbine performance and utilizing better materials for greater energy harvesting efficiency. © 2013 IEEE.
