This study explores linear encryption techniques to protect against information-based stealthy attacks on re-mote state estimation. Utilizing smart sensors equipped with local Kalman filters, the system transmits innovations rather than raw measurements via wireless networks. However, this transmission is susceptible to malicious data interception and manipulation by attackers. To safeguard against these stealthy threats, encryption and decryption modules are integrated into the system. This research aims to assess the effectiveness of the encryption strategy when faced with information-based stealthy attacks. A key contribution of this paper is the adoption of the most comprehensive attack models, moving away from the conventional reliance on innovation-based linear attack models. Our results demonstrate that the proposed linear encryption approach effectively mitigates stealthy attacks under certain mild conditions. The efficacy of the encryption is further validated through numerical examples, corroborating the theoretical advancements presented in this paper.

Recent years have witnessed the explosive growth of data annotation due to the deep learning algorithm's thirst for labelled datasets. To ease the workload of data annotation, researchers begin to concentrate on automatic dataset generation, i.e. dataset synthesis via virtual engine like Unity. However, the large domain gap between the target and simulated images hinders the great potential of these methods. In this paper, we propose a novel method to simulate labelled datasets under an image-level content consistent graph constraint. A detection model is applied to extract the semantic content of target and simulated images, and the corresponding scene graphs are constructed to compare the differences between them. This method not only utilizes the high-dimensional features of the images to reduce the content gap between target and simulated datasets, but also reserves the differentiability of the whole learning pipeline. As a result, we are able to automatically simualte labelled datasts in an end-to-end manner, and the models trained on the simulated datasets behave the best against existing methods.

IEEE International Conference on Robotics and Biomimetics

The trajectory tracking control task is of vital importance to the USV control system, especially when it is under-actuated. Focusing on the problem that the USV system model identification is difficult and the lateral motion control is usually affected by the environmental disturbance, we propose a novel USV trajectory tracking method that combines the control law with a data-driven state prediction algorithm. Due to the fact that the yaw of USV is usually calculated by a simplified dynamic model according to other state variables, accurate trajectory tracking control becomes quite difficult. Therefore, we replace the yaw calculation with a learning-based method based on the multi-sensor data captured from the USV in real-time. Our method takes the environmental factors into account while calculating the yaw variable. Simulation experiments are conducted and the comparison of 5 experimental data in the straight line and turning conditions shows that the average lateral displacement MSE error is reduced by 70.86% and 78.4% respectively compared with the model calculation method. The average tracking accuracy RMSE decreased by 43.47% and 42.31%, indicating the effectiveness of the method.

Soft fault detection for transmission lines is of great significance to secure electricity distribution network, since a soft fault will gradually develop into a hard fault or electrical fires. The existing detection methods are often applied to localize point-like faults, while most of soft faults are line-like faults with a certain length. Considering that soft faults will change the signal propagation speed, this paper establishes a transmission line model with respect to speed distribution. Then, a wavenumber domain reflectometry (WNDR) is developed to obtain the speed distribution using Volterra inverse scattering series (VISS). By dealing with zero wavenumber compensation and Gibbs ringing artifact suppression issues of VISS in the wavenumber domain, WNDR achieves not only localization but also imagination of fault length and dielectric permittivity for line-like faults, without the need of time synchronization and the knowledge of line topology. The simulation results show that WNDR locates the range of line-like faults more precisely than the existing fault detection methods, and achieves dielectric permittivity imagination with an accuracy larger than 97%. © 2023 IEEE.

Ltd. Jining China

In recent years, the rapid advancement of automation control and intelligent sensing technologies has positioned autonomous driving as a focal point of interest for both academia and industry. As core equipment in modern construction and industrial production, engineering machinery urgently requires intelligent transformation. To promote the intelligent development of engineering machinery, we have designed an integrated intelligent autonomous driving bulldozer system, which can be extended to various types of engineering machinery. For the specific mine dumping operation environment, we propose a multisensor fusion pose estimation algorithm framework based on the Global Navigation Satellite System, inertial measurement unit, visual cameras, and light detection and ranging (LiDAR) to address issues arising from sensor failures under harsh construction conditions. Furthermore, to ensure safety during task execution, we design a three-dimensional object detection method based on the optimal observation plane from LiDAR data. By integrating pose estimation and environmental perception results, we develop a comprehensive work planning and path-tracking algorithm to maintain task efficiency. Experimental results demonstrate that our intelligent autonomous driving bulldozer system performs excellently under various working conditions. The accuracy of its pose estimation, object detection, and path tracking meets the requirements of actual construction environments, showcasing its significant potential in engineering applications. © 2025 Wiley Periodicals LLC.

As a vital technology in the field of image processing, numerous visible and infrared fusion methods have emerged with the aim of generating a single image containing salient targets and abundant details. However, owing to the influence of target motion or camera shake, source images may suffer from motion blur, resulting in blurred edges and unrecognizable objects. To address this issue, this paper bridges the gap between deblurring and fusion tasks and proposes a joint motion deblurring and fusion network for visible and infrared image (MDbFusion). On the one hand, we innovatively merge motion deblurring task into network design, which effectively ensures the capacity of MDbFusion to process images in the extreme condition. On the other hand, an Adaptive Weight Module (AWM) is designed to calculate contribution between visible and infrared features, which solves the channel contrast between two tasks, greatly reducing the complexity of network. Extensive experiments demonstrate that the MDb-Fusion outperforms state-of-the-art (SOTA) fusion algorithms in terms of preserving texture details and quantitative metrics. Furthermore, we also compare with a two-step fusion strategy that first deblurring then fusion, both with SOTA methods. The results reveal superiority of our framework in coupling and reciprocity between two tasks.

This paper introduces a novel algorithm for recognizing speech emotions, utilizing an enhanced version of the ShuffleNet V2 network. Previous studies typically analyze speech signals solely from the time or frequency domain, resulting in the loss of detailed information. Our algorithm initially converts speech data into an acoustic spectrogram to address this limitation, preserving rich original information across both time and frequency domains. This approach optimizes feature extraction by leveraging the capabilities of deep convolutional networks to capture local changes in images. Furthermore, we integrated the attention mechanism from ECA-Net into the ShuffleNet V2 model. This incorporation enhances the extraction of significant features, amplifying the expression of features strongly correlated with the emotional state conveyed in speech while suppressing irrelevant ones. In addition to these enhancements, we replace the ReLU activation function with Hardswish to deepen the neural network, thereby improving feature information without compromising model accuracy. Finally, the training stage incorporates the hot restart Cosine Annealing Learning Rate to optimize the network further. Simulation experiments are conducted on the enterface'05 dataset to evaluate the accuracy of the proposed algorithm. The experimental results show that the recognition rate of the method is higher than the existing algorithms. © 2024, The Authors. All rights reserved.
