In this paper, the problem of cubature Kalman fusion filtering(CKFF) is addressed for multi-sensor systems under amplify-and-forward(AaF) relays. For the purpose of facilitating data transmission, AaF relays are utilized to regulate signal communication between sensors and filters. Here, the randomly varying channel parameters are represented by a set of stochastic variables whose occurring probabilities are permitted to exhibit bounded uncertainty. Employing the spherical-radial cubature principle, a local filter under AaF relays is initially constructed. This construction ensures and minimizes an upper bound of the filtering error covariance by designing an appropriate filter gain. Subsequently, the local filters are fused through the application of the covariance intersection fusion rule. Furthermore, the uniform boundedness of the filtering error covariance's upper bound is investigated through establishing certain sufficient conditions. The effectiveness of the proposed CKFF scheme is ultimately validated via a simulation experiment concentrating on a three-phase induction machine.

In this paper, a unified influence networks model incorporating differential privacy mechanisms (DPMs), called the differentially private opinion dynamics (DPODs) model is proposed. In this model, each individual uses protected opinions rather than the private opinions of his/her neighbors to update his/her private opinions, where the protected opinion of an individual is a blend of private opinions and random noise following Laplace distribution. Building on stochastic analysis techniques and matrix theory, we show that the influence network under consideration converges under specific conditions governing individual sensitivities and interaction weights. In addition, the statistical properties related to convergence accuracy are established by utilizing the Markov inequality to estimate a lower bound on the probability of all individuals' final opinions converging to a neighborhood formed by their initial opinions' convex hull. We further conduct a differential privacy analysis to validate the efficacy of the proposed DPMs in safeguarding the private opinions of all individuals. Finally, two examples including one of the Karate-Club networks are provided to shed new light on the effectiveness of the theoretical results. © 2014 IEEE.

The detection and isolation of early and minor faults in electric vehicle battery systems is vital to safe driving and improving energy efficiency. The Support Vector Data Description (SVDD) is a widely popular algorithm for anomaly detection under complex distribution. However, it faces three significant challenges in fault detection and isolation for electric vehicle battery systems: high missed detection rate, unachievable fault isolation and difficult hyperparameter selection. To address these issues, this paper proposes a novel semi-supervised method named KDSVDD by introducing kernel space partial differential and Bayesian Optimization to expand SVDD. This method incorporates a small amount of lab.led fault data and constructs the semi-supervised model to refine the decision boundary, effectively decreasing the fault missed rate. By calculating the relative contribution of variables to faults using partial differential in kernel space, a unified contribution plot is generated, effectively solving the challenge of fault isolation that SVDD cannot overcome. In addition, Bayesian Optimization is employed to obtain the optimal hyperparameter combination quickly and effectively, which improves the performance of fault detection and isolation. The experimental results indicate that this method outperforms others in terms of detection time, accuracy, and robustness across datasets with different fault types, particularly in detecting early and minor faults. Additionally, it achieves the isolation ability for different faults, from the moment of occurrence to termination, effectively identifying and pinpointing the fault source. © 2025

This study investigates the network-based fixed-time stabilization problem of the direct drive wheel (DDW) system of electric vehicles under stochastic cyber-attacks and intermittent denial of service (DoS) attacks via reliable discontinuous control strategy, which has important research significance for the application of the communication network security of the direct drive wheel system of electric vehicles. Firstly, aiming at the fact that the widths of control channels induced by stochastic cyber-attacks are inconsistent, a new controller based on quantization discontinuous delay control method is designed. Secondly, the actuator fault is also taken into account to conform to the actual operation of the direct drive wheel system of electric vehicles. Moreover, given the reliability of controllers in practical engineering, this work develops a new sufficient condition for easy implementation based on Lyapunov functional, and construct a new reliable discontinuous safety controller with stochastic cyber-attacks and intermittent DoS attacks to control the stability of the direct drive wheel system of electric vehicles in fixed time. Finally, the correctness and feasibility of the developed theoretical results are verified by experiments. © 2015 IEEE.

In order to increase the capacity of encrypted information and reduce the loss of information transmission, a three-dimensional(3 D) scene encryption algorithm based on the phase iteration of the angular spectrum domain is proposed in this paper. The algorithm, which adopts the layer-oriented method, generates the computer generated hologram by encoding the three-dimensional scene. Then the computer generated hologram is encoded into three pure phase functions by adopting the phase iterative algorithm based on angular spectrum domain,and the encryption process is completed. The three-dimensional scene encryption can improve the capacity of the information,and the three-phase iterative algorithm can guarantee the security of the encryption information. The numerical simulation results show that the algorithm proposed in this paper realized the encryption and decryption of three-dimensional scenes. At the same time, it can ensure the safety of the encrypted information and increase the capacity of the encrypted information.

Exciting dark plasmon mode using heterogeneous hybrid cylindrical nanostructure for SERS detection

Physics Letters A 2025年 552卷

In this study, we engineered a novel SERS substrate featuring a coupled Metal-Dielectric-Metal (MDM) dimer structure integrated with a metal nanorod array, where small metal nanorods are strategically positioned within the nanoscale gaps. The hotspot enhancement effect of the SERS substrates was optimized by modulating the number of metal nanorods and the materials of the MDM nanocylinders, thereby extending the plasmonic decay time of the nanostructures. Compared to a pure silver dimer nanostructure, this MDM nanostructure enhances the local electric field intensity by up to ∼150-fold at the same gap width. Furthermore, we elucidate the underlying mechanisms: (1) the excitation of a dark hybrid plasmon mode in the nanogap, and (2) the controlled manipulation of the LSPR mode. These findings are expected to significantly advance the design of larger and more intense hotspot regions for SERS substrates.

The problem of asymptotic tracking control for a vertical take-off and landing (VTOL) aircraft system is addressed in this paper, in which unknown external disturbances and nonlinear dynamics are added. Unknown nonlinear dynamics are deal with by using neural networks, and some adaptive laws are addressed. Additionally, some control laws for unknown parameters are developed to address unknown nonlinearities resulting from the analysis process. Based on the dynamic surface control approach and neural network control, the adaptive control laws with dynamic surface method and neural network are developed for the system. The results show that the developed control laws insure that the system under consideration asymptotically follows the given desired signal, and the system's tracking errors can converge to zero. At last, a simulation case is shown to validate the effectiveness of developed control strategies. © 2023 IEEE.
