In recent years, multi-agent systems are becoming more complex, scalable, adaptive, and integrating machine learning for enhanced capabilities. A popular approach for addressing this challenge involves the utilisation of artificial potential functions (APF). In this article, we address the problem of obstacle avoidance and achieving a predefined formation, particularly promoting smooth trajectory generation in multi-agent formation control. We employ the APF method to enhance the smoothness of the agents’ movement paths during these tasks. Collision damping terms are generated by differentiating the gradient of APF with respect to time. Incorporating generated damping terms in the APF control, we suppress irregular fluctuations during agents’ motion procedures. To ensure stability in the multi-agent system, we design an energy-based Lyapunov function and utilise it for proof. Simulation examples are presented to validate the theoretical results and demonstrate the advantages of the proposed control algorithm. Through these simulations, it becomes evident that the collision-free formation control algorithm enhances the smoothness of the agents’ trajectories. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

In order to satisfy the modulation recognition requirements for radar signal with agility pulse-width, bandwidth and modulation type, the multi-scale self-correlation combined with layered convolution-GRU network is proposed in this paper. First, the waveform is processed by multi-scale self-correlation with different accumulation points to obtain the time-amplitude and time-frequency information; Second, the local characteristics were extracted by layered convolution network respectively; Lastly, the local characteristics of each self-correlation are integrated, and the GRU network is adopted to extract the serialization representation. The proposed network combines the advantages of local characteristics of CNN and the sequence characteristics of GRU. The simulation shows that the modulation recognition accuracy is more than 95.4% over the detection sensitivity for normal, LFM, NLFM, FSK, BPSK, QPSK signals.

Semi-supervised learning has garnered significant attention, particularly in medical image segmentation, owing to its capacity to leverage a large number of unlabeled data and a limited amount of labeled data to improve performance. However, most existing semi-supervised segmentation methods exhibit shortcomings in supervising unlabeled data, both in the label space due to potential noise in pseudo-labels, and the feature space due to indistinct class boundaries. To address the issues above, we propose Dual-view Label and Feature Supervision Network, termed DLFS-Net, to enhance label and feature supervision for unlabeled data. Our approach is based on a dual-view learning strategy that incorporates two modules: the Confidence Fusion Supervision Module (CFS) and the Dual-view Prototype Learning Module (DPL). Specifically, the CFS module generates weight matrices to integrate complementary information from two model outputs, producing more accurate pseudo-labels in the label space. The DPL module reduces intra-class variations in the feature space from two different views through prototype learning to generate clear class boundaries. Experiments on the LA and Pancreas-CT datasets demonstrate that our framework show solid gains (e.g.,1.76% Dice and 2.37% Jaccard improvement on Pancreas-CT dataset with 20% labeled data) compared with the state-of-the-art methods. © 2024 ACM.

In this paper, we propose a control concept that the control system based on fuzzy control algorithm is used in external magnetic field control system, and this control system is used to control the intestinal robot. First, modelling and control of magnetic actuated intestinal robot with image acquisition function is proposed in this paper. Then, hydrodynamic simulation is introduced to simulate the modelling of proposed intestinal robot to verify the rationality and feasibility. Finally, using fuzzy controller, a simple control system based on the fuzzy control algorithm is proposed to control external magnetic field in this paper. Experimental results showed that the proposed robot can withstand simulated experimental conditions, and it has a good performance on the feasibility and rationality of structure which are verified by hydrodynamic simulation experiments. © 2023 IEEE.

In response to discrete industrial processes characterized by unmeasurable states, actuator faults, and time delays, a novel robust predictive fault-tolerant control approach based on dynamic output feedback is proposed. First, we establish an innovative iterative error model that expands the notion of output tracking error to guarantee superior tracking performance for the system. Subsequently, based on the dynamic output feedback method, a robust predictive fault-tolerant controller is developed utilizing this model. By employing Lyapunov stability theory, linear matrix inequality (LMI) techniques, relaxation strategies, and variable transformation methods, stability conditions are given in the form of LMI. Real-time optimal control gains are obtained by online solving of these stability conditions, leading to a significant enhancement in control performance. The feasibility and effectiveness of the proposed approach are finally demonstrated through a simulation case study involving the TTS20 water tank. © 2023 IEEE.

Halide perovskites exhibit high performance in all sorts of optoelectronic and photonic areas, suggesting their huge potential in integrated photonic devices. However, until now, all optical logic gates based on perovskites are still rarely explored, hindering the development of all-optical networks and computing. Herein, a new concept of all-optical logic gates is proposed based on the modulation of photoluminescence(PL) from perovskite nanocrystals(PNCs). A hierarchical photonic crystal(Hie PhC) is developed by self-assembling polystyrene(PS) and SiO2nanoparticles, which exhibit a higher PL enhancement than that of a monolayer PhC. Moreover, the light-controlled PL is realized by taking advantage of the high thermal response of the PL from PNCs/Hie PhC on polyethylene(PE) substrate, assisted by a graphene layer for light-heat conversion. Consequently, optical diode and triode are achieved based on the modulated PL, which exhibit contrast ratios(CR) of 24.7 and 74.0 dB, ***-optical logic gates, including “AND”, “OR” and “NOT”, are realized based on the optical diode and triode.

In this article, we present a switchable frequency selective surface (FSS) featuring angular stability and polarization symmetry (transmission/reflection). The proposed structure comprises two orthogonal distributions of active FSSs printed on a dielectric substrate. By altering the state of the PIN diode (ON/OFF), two distinct switchable electromagnetic functions (transmission/reflection) are achieved within the x-band frequency range. Furthermore, we analyze the behavior of the switchable transmission/reflection FSS, using equivalent circuit models (ECMs). © 2024 IEEE.
