Given the shortcomings of the traditional Golden Jackal Optimization (GJO) algorithm, including limited accuracy and slow convergence speed in solving mobile robot path planning problems, an improved adaptive Golden Jackal Optimization (IAGJO) method is proposed. Firstly, a nonlinear adaptive energy strategy is presented to adjust the energy decay pattern, balancing global and local search. Secondly, an enhanced position update mechanism based on Cauchy and Gaussian mutation increases population diversity and guide the search based on optimal individuals, thereby facilitating efficient exploration of unknown regions and avoiding local optima. Finally, the IAGJO algorithm is applied to mobile robot path planning (MRPP), demonstrating that the IAGJO achieves shorter path lengths and higher search efficiency, exhibiting significant advantages over existing methods. © 2025 SPIE.

This paper explores the critical issue of enhancing cybersecurity measures for low-cost, Wi-Fi-based Unmanned Aerial Vehicles (UAVs) against Distributed Denial of Service (DDoS) attacks. In the current work, we have explored three variants of DDoS attacks, namely Transmission Control Protocol (TCP), Internet Control Message Protocol (ICMP), and TCP + ICMP flooding attacks, and developed a detection mechanism that runs on the companion computer of the UAV system. As a part of the detection mechanism, we have evaluated various machine learning, and deep learning algorithms, such as XGBoost, Isolation Forest, Long Short-Term Memory (LSTM), Bidirectional-LSTM (Bi-LSTM), LSTM with attention, Bi-LSTM with attention, and Time Series Transformer (TST) in terms of various classification metrics. Our evaluation reveals that algorithms with attention mechanisms outperform their counterparts in general, and TST stands out as the most efficient model with a run time of ~0.1 seconds. TST has demonstrated an F1 score of 0.999, 0.997, and 0.943 for TCP, ICMP, and TCP + ICMP flooding attacks respectively. In this work, we present the necessary steps required to build an onboard DDoS detection mechanism. Further, we also present the ablation study to identify the best TST hyperparameters for DDoS detection, and we have also underscored the advantage of adapting learnable positional embeddings in TST for DDoS detection with an improvement in F1 score from 0.94 to 0.99.

Machine vision has numerous uses and is currently at the forefront of research in this field. In this paper, for monocular vision systems, we mainly compare the monocular camera hand-eye calibration results and errors of two vision software platforms, and analyze the possible causes of errors to provide an idea for obtaining accurate hand-eye calibration results. And this paper derives the accuracy chain of hand-eye calibration from the whole process of hand-eye calibration, and analyzes the causes of errors in the hand-eye calibration results from each link in the accuracy chain. The results show that the accuracy of the hand-eye calibration results of Halcon software platform is higher than that of OpenCV calibration results, and the error from the robot arm can be reduced by using the relative coordinate system of the robot arm considering the direction of the hand-eye calibration accuracy chain analysis.

With the development of computer-related technologies, robot technology and machine vision technology have also been greatly improved. The intelligent sorting system composed of traditional robots and machine vision can not only reduce production costs, but also improve the efficiency and accuracy of sorting operations. With these advantages, the machine sorting system is gradually replacing the manual sorting system. It develops in the direction of networking, automation, collaboration and intelligence, and has extremely broad development prospects. Therefore, this paper discusses and analyzes the composition, classification and application of the intelligent sorting system in detail, and expounds the key technologies. At the same time, the intelligent sorting system proposed in this paper is introduced. Finally, the current development of intelligent sorting system is summarized, and the future development trend is prospected.

This study investigates the effects of data transformation techniques on the performance of various machine learning classification models. Specifically, the standard scaler (or Z-score) and min-max scaler techniques coupled with several machine learning and statistical algorithms, including K-Nearest Neighbors, Naive Bayes, Support Vector Machine, and Logistic Regression (LR), are examined systematically. Based on a set of student performance data from an institution, application of the resulting model to predicting student dropout rate is demonstrated. The empirical results indicate that LR with a standard scaler yields the highest AUC (area under the receiver operating characteristic curve) score of 89.95%. © 2024 IEEE.

In this study, a delicate fractional-order fast terminal sliding mode controller is proposed for the position and attitude tracking of a quadrotor UAV under actuator saturation. In this controller, the fractional order calculus is incorporated to the fast terminal sliding mode surface design, which can enhance the convergence speed of the controlled UAV system. Meanwhile, to solve the problem of actual control input limitation, a RBF-based estimator is designed to evaluate the error between the virtual control input and actual control output. The stability of the controlled system is proved by using Lyapunov theorem, where the validity and effectiveness of the proposed controllers and estimator are verified by a detailed numerical simulation. © 2023 IEEE.

The problem of high-precision attitude tracking is studied in this paper under model uncertainty and external disturbance risk. First of all, the kinematics and dynamics model of rigid body is derived based on the quaternion theory. Then, a standard logarithmic sliding-mode function is constructed using the attitude quaternion and its derivatives of the rigid spacecraft, and the corresponding logarithmic sliding-mode controller is also derived. Finally, the stability of the controlled closed-loop system is demonstrated. Consistenting with theoretical proof, the numerical simulation results showed that the controlled rigid body can quickly track its desired attitude command, even if there are model uncertainty and external disturbance risks. © 2023 IEEE.
