Social media is a platform for people to share their lives and interact with others. Image sharing is an integral component. Privacy information will inevitably be compromised during the process of sharing whole photos. Sometimes, it is not even caused by the person who shares the image but the third party who forwards the image. In the majority of cases, we do not attempt to protect the entirety of the media;rather, we seek to protect the most crucial portion, whether it is the background or specific objects, which decreasing superfluous cryptography procedures. Unfortunately, current research on such field is extremely rare. In this research, we established a novel pixel-level image encryption technique relying on Panoptic FCN panoramic segmentation and chaos for client-intended images on social media sites. Our suggested technology is capable of automated picture encryption on either the whole images or user-selected areas, whether they are rectangular or irregular, which is suited for all region of interest (ROI) encryption. Relying on a novel coupled chaotic map, this universal new encryption method flattens the array of the image ROI into a series of pixels. The module of Panoptic FCN can be replaced by any other panoptic segmentation models which are stronger in performance. Statistical and cryptographic evaluations demonstrate that our technique preserves the high efficiency for practical applications. © 2023 SPIE. All rights reserved.

This paper examines the event-triggered consensus of the multi-agent system on matrix-weighted networks, where the interdependencies among higher-dimensional states of neighboring agents are characterized by matrix-weighted edges in the network. Specifically, a novel distributed dynamic event-triggered coordination strategy is proposed for this category of generalized networks, in which an auxiliary system is employed for each agent to dynamically adjust the triggering threshold, which plays an essential role in guaranteeing that the triggering time sequence does not exhibit Zeno behavior. Distributed event-triggered control protocols are proposed to guarantee leaderless consensus for multi-agent systems on matrix-weighted networks, respectively. Remarkably, the spectrum of matrix-valued weights is crucial in event-triggered mechanism design for matrix-weighted networks, generalizing those results only applicable for scalar-weighted networks. The proposed approach allows each agent to broadcast and receive information only at its triggering instants. Finally, simulation examples are provided to demonstrate the theoretical results. © 2023 Technical Committee on control Theory, Chinese Association of Automation.

In this paper, a second-order fully actuated system model is derived for a six degree of freedom aircraft model with control coupling. Then a three channel joint optimal attitude control method of roll, yaw and pitch is designed on high-order fully actuated system theory. Through mathematical simulation of this controller and the traditional PID controller, it is shown that the PID control method has a great shortage in the aircraft with control coupling, and the fully actuated system theory control method can well solve the problem of aircraft coupling, achieve the stable tracking of aircraft attitude command, and has better rapidity.

Aiming at the problem that the accuracy of observation data is affected by the vibration generated by the floating tide gauge under the excitation of waves and sailing, this paper builds a mechanical model of the spring vibration system with two degrees of freedom based on the tidal observation principle and the mechanical characteristics of the float-rope wheel-heavy hammer, and studies the influence of external stiffness on the vibration of the system. The dynamics equation of the system was established and the relationship between the stiffness and natural frequency was deduced. According to the F- K method and the micro wave theory, the wave force of the float is analyzed and the equation of its force motion is obtained. Finally, Matlab Simulink was used to calculate the system model, and the vibration response of the heavy hammer and float was obtained. The vibration response is simple harmonic motion, and the stiffness will reduce the amplitude and speed of vibration. When the stiffness is greater than 4000N/m, the maximum vibration amplitude at the hammer is less than lcm, which meets the site application requirements. © 2023 IEEE.

Bokeh effect transformation is a novel task in computer vision and computational photography. It aims to convert bokeh effects from one camera lens to another. To this end, we introduce a new concept of blur ratio, which represents the ratio of the blur amount of a target image to that of a source image, and propose a novel framework SBTNet based on this concept. For cat-eye simulation and lens type transformation, a two-channel coordinate map and a two-channel one-hot map are added as extra inputs. The core of the framework is a sequence of parallel FeaNets, along with a feature selection and integration strategy, which aims to transform the blur amount with arbitrary blur ratio. The effectiveness of the proposed framework is demonstrated through extensive experiments, and our solution has achieved the top LPIPS metric in NTIRE 2023 Bokeh Effect Transformation Challenge. © 2023 IEEE.

Game-based Secondary control for DC Microgrids with Nash Equilibrium

引用

IEEE Transactions on Energy Conversion 2025年

作者： Yuan, Qi-Fan Wang, Yan-Wu Liu, Xiao-Kang Guo, Kai-Yuan Huazhong University of Science and Technology Key Laboratory of Image Processing and Intelligent Control School of Artificial Intelligence and Automation Wuhan430074 China

Voltage regulation and current sharing are two major issues when designing distributed control strategies for DC microgrids. However, power supply economy of local generators also needs to be considered. In this paper, a game-based framework is constructed, where multiple generators are regarded as the participants with secondary control signals being the game actions. A distributed secondary control algorithm is proposed, while information mask is introduced to avoid transmitting true control signal to neighbors. Then, payoff function is designed for each generator, which is composed of voltage regulation error, current sharing error and the local generation cost. It is proved that under the proposed secondary control algorithm in conjunction with the payoff function, a unique Nash equilibrium can be reached. Consequently, the minimum of the payoff function can be achieved, where the optimization of system control behavior and local economic operation can be realized simultaneously. Numerical simulations and experimental tests are carried out to demonstrate the effectiveness of the proposed secondary control strategy within several scenarios. © 1986-2012 IEEE.

A novel split ring (SR) wide-angle impedance matching (WAIM) printed on a double-layer PCB was designed to replace the dielectric slabs WAIM or frequency selective surface (FSS) WAIM with high profile. The proposed WAIM is designed together with tightly coupled dipole array (TCDA). Consequently, TCDA loaded with the proposed double-layer SR achieves a impedance bandwidth of 8.5:1(2.12-18 GHz ) with active VSWR＜3.2 at broadside; while scanning up to {60°,75°}in E-plane, a bandwidth of {8.2:1 (2.17-17.91GHz) , 6.1:1(2.91-17.43GHz)} is achieved; while scanning up to 45°in H-plane, a bandwidth of 6.8:1(2.55-16.77GHz) is achieved. Compared to the FSS loaded TCDA with a 0.078λ l profile, the double layer SR loaded TCDA can ensure wideband, wide-angle scanning capability with a lower profile of 0.058λ l (λ l is the free-space wavelength at the lowest frequency).

The expeditious progress of information technology has encouraged the digital enhancement of the educational sector. To remedy the issues of the traditional teaching mode, a blended teaching mode of engineering drawing course has been developed with the use of smart education technology. Based on the Outcomes-based Education ( OBE ), the teaching objectives and teaching contents of the course are reconstructed by using the method of reverse design and forward implementation. By leveraging the synergy of online and offline, virtual and real, and quantitative and qualitative evaluation, a blended teaching approach that is both student-centered and teacher-guided is realized. A course knowledge graph has been built, offering fresh concepts for accomplishing personalized learning for students. The teaching practice shows that the blended teaching mode based on intelligent education has created a multi-dimensional autonomous learning space and personalized learning path for students, which effectively improves the enthusiasm and initiative of students to participate in teaching activities, and also improves the information level of teaching process and management, and promotes the organic integration of teaching and learning. © 2024 ACM.
