Local Search-Based Anytime Algorithms for Continuous Distributed Constraint Optimization Problems

IEEE/CAA Journal of Automatica Sinica 2025年第1期 288-290页

作者： Xin Liao Khoi Hoang Xin Luo the College of Computer and Information science Southwest University the Department of Computer science and Engineering Washington University in St.Louis IEEE

Dear Editor,The distributed constraint optimization problems(DCOPs) [1]-[3]provide an efficient model for solving the cooperative problems of multi-agent systems, which has been successfully applied to model the real-world problems like the distributed scheduling [4], sensor network management [5], [6], multi-robot coordination [7], and smart grid [8]. However, DCOPs were not well suited to solve the problems with continuous variables and constraint cost in functional form, such as the target tracking sensor orientation [9], the air and ground cooperative surveillance [10], and the sensor network coverage [11].

One-step synthesis of graphitic-C_3N_4/ZnS composites for enhanced supercapacitor performance

Journal of Energy Chemistry 2018年第2期27卷 472-477页

作者： Binbin Wei Hanfeng Liang Rongrong Wang Dongfang Zhang Zhengbing Qi Zhoucheng Wang College of Chemistry and Chemical Engineering Xiamen University Materials science and Engineering King Abdullah University of Science and Technology (KAUST) School of Materials science and Engineering Xiamen University of Technology

A series of graphitic-C3N4/ZnS（g-C3N4/ZnS） supercapacitor electrode materials have been prepared via a one-step calcination process of zinc acetate/thiourea with different mass ratios under nitrogen atmosphere. The optimized g-C3N4/ZnS composite shows a highest specific capacitance of 497.7 F/g at 1 A/g and good cycling stability with capacitance retention of 80.4% at 5 A/g after 1000 cycles. Moreover, gC3N4/ZnS composites display an improved supercapacitor performance in terms of specific capacitance compared to the pure g-C3N4 and ZnS. In addition, our designed symmetric supercapacitor device based on g-C3N4/ZnS composite electrodes can exhibit an energy density of 10.4 Wh/kg at a power density of 187.3 W/kg. As a result, g-C3N4/ZnS composites are expected to be a prospective material for supercapacitors and other energy storage applications.

Judging or setting weight steady-state of rational Bézier curves and surfaces

引用

Applied Mathematics(A Journal of Chinese Universities) 2014年第4期29卷 391-398页

作者： CAI Hong-jie WANG Guo-jin Department of Mathematics Zhejiang University Mathematics and Applied Mathematics Foshan University

Many works have investigated the problem of reparameterizing rational B^zier curves or surfaces via MSbius transformation to adjust their parametric distribution as well as weights, such that the maximal ratio of weights becomes smallerthat some algebraic and computational properties of the curves or surfaces can be improved in a way. However, it is an indication of veracity and optimization of the reparameterization to do prior to judge whether the maximal ratio of weights reaches minimum, and verify the new weights after MSbius transfor- mation. What＇s more the users of computer aided design softwares may require some guidelines for designing rational B6zier curves or surfaces with the smallest ratio of weights. In this paper we present the necessary and sufficient conditions that the maximal ratio of weights of the curves or surfaces reaches minimum and also describe it by using weights succinctly and straightway. The weights being satisfied these conditions are called being in the stable state. Applying such conditions, any giving rational B6zier curve or surface can automatically be adjusted to come into the stable state by CAD system, that is, the curve or surface possesses its optimal para- metric distribution. Finally, we give some numerical examples for demonstrating our results in important applications of judging the stable state of weights of the curves or surfaces and designing rational B6zier surfaces with compact derivative bounds.

Reputation-based secure spectrum situation fusion in distributed cognitive radio networks

引用

The Journal of china Universities of Posts and Telecommunications 2015年第3期22卷 110-117页

作者： Li Fangwei Liu Fan Zhu Jiang Nie Yifang School of Communication and Information Engineering Chongqing University of Posts and Telecommunications

In distributed cognitive radio （CR） network, the cooperative spectrum situation sensing based on consensus scheme may be disrupted by spectrum sensing data falsification （SSDF） attacks. In this paper, a secure spectrum situation fusion scheme based on reputation is proposed to counter attacks. The neighboring nodes of secondary users （SUs） get the corresponding dynamic trust value according to their behavior, which restrict the impact of the malicious behavior on the premise to ensure information interaction of normal nodes. Theoretical analysis and simulation results show that the consensus fusion scheme based on reputation has better performance than the existing algorithm which eliminates the neighboring node with the biggest deviation value from mean value. It demonstrates that the proposed scheme not only achieves better convergence properties but also has higher detection probability than the existing scheme in the process of spectrum situation fusion.
