Underwater supporting robots serving as a relay of energy supplements and communication for other underwater equipment are promising for ocean exploration, development, and protection. This paper proposes a novel autonomous docking system centered on a designed supporting robotic fish named 'CourierFish'. Specifically, CourierFish is capable of docking with a surface dock station for supplying itself and docking with a seafloor platform for supporting equipment in the platform. A visual navigation scheme integrating LED and ArUco markers is presented for accurate localization. The control approach for docking motion is also illustrated. Simulations and aquatic experiments are performed to verify the feasibility of the proposed docking system. The obtained results lay a solid foundation for the construction of various underwater equipment and robot networks. © 2023 IEEE.

The global energy sector is transforming significantly, driven by the need for an efficient and sustainable generation with the goal of net-zero carbon emissions. Microgrids (MGs) have therefore risen to the challenge by facilitating the decentralization of power supply and consumption. This paper proposes a Bi-Level Optimization approach to promote optimal decision-making in Networked Microgrids (NMGs) by leveraging the real-time data processing capabilities of edge-fog devices. Furthermore, the study seeks to optimize both independent MG and NMG, in a bid to achieve cost optimization. To accomplish this, the framework utilizes two optimization strategies: an internal Mixed-Integer Nonlinear Programming (MINLP) optimizer within the microgrids to minimize costs and optimize energy source utilization at the MG level, and an external MINLP optimizer at the fog level to handle energy transactions between the MGs. The simulation analysis on Australian grid data demonstrates that this framework effectively decreases operational expenses by efficiently managing energy use inside and between MGs, improving cost effectiveness by 19.5%.

In textile processing companies, after purchasing fabric, dyeing, and other treatments, such as surface finishing are carried out before shipping. Defect detection technology is one of the most important issues in this field. Because if we ship a defective fabric without noticing the defect, it will cause damage to the delivery destination. Previously, defect detection of fabric has been performed using methods such as CNN. However, conventional methods such as general multilayer neural networks require two separate processing stages: object detection and identification. Therefore, there is a problem that sufficient real-time performance cannot be guaranteed in the inspection process on an actual manufacturing line. Therefore, in this study, we construct a fabric defect detection system using YOLO which is capable of real-time object detection. In the future, we aim to realize the automation of textile defect detection systems by the construction of an image recognition system using machine learning. It is expected that this will result from reduced detection errors by the human eye, improve detection accuracy, and reduce labor costs.

Scalable intensity-based photonic matrix-vector multiplication processor using single-wavelength time-division-multiplexed signals

Optics letters 2025年第11期50卷 3656-3659页

Photonic integrated circuits provide a compact platform for ultrafast and energy-efficient matrix-vector multiplications (MVMs) in the optical domain. Recently, schemes based on time-division multiplexing (TDM) have been proposed as scalable approaches for realizing large-scale photonic MVM processors. However, existing demonstrations rely on coherent detection or multiple wavelengths, both of which complicate their operations. In this work, we demonstrate a scalable TDM-based photonic MVM processor that uses only single-wavelength intensity-modulated optical signals, thereby avoiding coherent detection and enabling simplified operations. A 32-channel processor is fabricated on a Si-on-insulator (SOI) platform and used to experimentally perform convolution operations in a convolutional neural network (CNN) for handwritten digit recognition, achieving a classification accuracy of 93.47% for 1500 images.

Nowadays, traffic accidents not only come from public transportation but also from pedestrians. Therefore, designing a solution to protect pedestrian safety is essential. This article proposes a system for forewarning the crossing intentions of pedestrians, comprising the tasks of detection, tracking, and intention prediction. Firstly, our proposed system performs the detection and pose estimation of pedestrians using the YOLOv7-Pose model. Subsequently, the OC-SORT algorithm is employed for the tracking task. Ultimately, an efficient architecture based on the VoVNet backbone and Temporal Shift Module is provided to forewarn whether pedestrians will cross the road or not. The input of the proposed network in multimodality includes RGB image or semantic image map, keypoints, and vehicle speed. In addition, the bag-of-freebies technique is applied to enhance the model's overall performance and address the issue of biased model creation caused by imbalanced data. Comprehensive experiments performed on the JAAD benchmark dataset demonstrate that our proposed method performs better than existing benchmark classification models. © 2024 IEEE.

This paper constructs a non-cooperative/cooperative stochasticdifferential game model to prove that the optimal strategies trajectory ofagents in a system with a topological configuration of a Multi-Local-Worldgraph would converge into a certain attractor if the system’s configuration isfixed. Due to the economics and management property, almost all systems aredivided into several independent Local-Worlds, and the interaction betweenagents in the system is more complex. The interaction between agents inthe same Local-World is defined as a stochastic differential cooperativegame;conversely, the interaction between agents in different Local-Worldsis defined as a stochastic differential non-cooperative game. We construct anon-cooperative/cooperative stochastic differential game model to describethe interaction between agents. The solutions of the cooperative and noncooperativegames are obtained by invoking corresponding theories, and thena nonlinear operator is constructed to couple these two solutions *** last, the optimal strategies trajectory of agents in the system is proven toconverge into a certain attractor, which means that strategies trajectory arecertainty as time tends to infinity or a large positive integer. It is concluded thatthe optimal strategy trajectory with a nonlinear operator of cooperative/noncooperativestochastic differential game between agents can make agentsin a certain Local-World coordinate and make the Local-World paymentmaximize, and can make the all Local-Worlds equilibrated;furthermore, theoptimal strategy of the coupled game can converge into a particular attractorthat decides the optimal property.
