2Magnetic and microwave absorption properties of Ni_(1-x)Zn_xFe_2O_4 nanocrystalline synthesized by sol-gel method显示文摘Ni1-xZnxFe2O4(0≤x≤1,in steps of 0.1) nanocrystallines were synthesized by sol-gel route.The doping effects of zinc on structural,magnetic and microwave absorption properties were investigated in detail.X-ray diffraction(XRD) results show that all the samples are single-phase spinel structure.The magnetic and microwave absorption properties are strongly dependent on the zinc content,which can be understood in terms of the cations redistribution in spinel tetrahedral and octahedral sites with the increase of zinc content.The magnetic measurement shows the antiferromagnetic nature of the samples for x=0.9 and x=1.0.The saturation magnetization reaches the maximum of 3.35μB/f.u.at x=0.5.The optimal reflection loss(RL) of-29.6 dB is found at 6.5 GHz for an absorber thickness of 5 mm.The RL values exceeding 10 dB are obtained for the absorber in the range of 3.9-8.9 GHz.These Ni1-xZnxFe2O4 nanocrystallines may be attractive candidates for electromagnetic wave absorption materials.ZHANG Min LIU QiangChun ZI ZhenFa DAI YuQiang ZHU XueBin SUN YuPing DAI JianMing 2013Science China(Technological Sciences)2013,56,1:4
3Modeling and Finite-Time Tracking Control for Mobile Manipulators with Affine and Holonomic Constraints显示文摘This paper focuses on the problem of modeling and finite-time tracking control for mobile manipulators with affine and holonomic constraints.A reduced dynamic model is obtained by appropriately processing affine and holonomic constraints,respectively.Then finite-time tracking controllers are designed to ensure that output tracking errors of closed-loop system converge to zero in finite time while the constraint force remains bounded.Finally,detailed simulation results are provided to confirm the effectiveness of the control strategy.SUN Wei WU Yuqiang 2016Journal of Systems Science & Complexity2016,29,3:3
4Adaptive Tracking Control for Mobile Manipulators with Stochastic Disturbances显示文摘This paper investigates adaptive tracking control for mobile manipulators with stochastic disturbances and parametric uncertainties. Based on an appropriate reduced dynamic model and an adaptive law, a controller, which is provided by incorporating stochastic control theory with related adaptive technique, overcomes the problem of over-parametrization. It is shown that the designed state-feedback controllers can guarantee that the mean square of the tracking errors can be made arbitrarily small by choosing suitable design parameters. Simulation studies on the control of 2-DOF mobile manipulator shows the effectiveness of the proposed scheme.SUN Wei XIA Jianwei WU Yuqiang 2019Journal of Systems Science & Complexity2019,32,5:3

8Modeling and adaptive motion/force tracking for vertical wheel on rotating table显示文摘This paper is devoted to the problem of modeling and adaptive motion/force tracking for a class of nonholonomic dynamic systems with affine constraints(NDSAC): a vertical wheel on a rotating table. Prior to the development of tracking controller,the dynamic model of the wheel in question is derived in a meticulous manner. A continuously differentiable friction model is also considered in the modeling. By exploiting the inherent cascade interconnected structure of the wheel dynamics, an adaptive motion/force tracking controller is presented guaranteeing that the trajectory tracking errors asymptotically converge to zero while the contact force tracking errors can be made small enough by tuning design parameters. Simulation results are provided to validate the effectiveness of the proposed tracking methodology.Zhongcai Zhang Yuqiang Wu Wei Sun 2015Journal of Systems Science & Complexity2015,28,5:1

17Synchronization clusters located on epileptic onset zones in neocortical epilepsy显示文摘Background Brain function is thought to rely on complex interactions of dynamic neural systems,which depend on the integrity of structural and functional networks.Focal epilepsy is considered to result from excessive focal synchronization in the network.Synchronization analysis of multichannel electrocorticography(ECoG)contributes to the understanding of and orientation of epilepsy.The aim of this study was to explore the synchronization in multichannel ECoG recordings from patients with neocortical epilepsy and characterize neural activity inside and outside the onset zone.Methods Four patients with neocortical epilepsy,who became seizure-free for more than 1 year after surgery guided by ECoG monitoring,were included in this study.ECoG data recorded during pre-surgical evaluation were analyzed.Synchronizations in phase and amplitude of different frequency bands between ECoG channels was analyzed using MATLAB.We generated 100 surrogate data from the original ECoG data using Amplitude Adjusted Fourier Transform to calculate the enhanced synchronization.The relationship between synchronization characteristics and seizure onset zone was analyzed.Results We found synchronization clusters in the 14–30 Hz and 30–80 Hz bands around the onset areas during both interictal and the beginning of ictal periods in all four patients.Conclusions The enhanced-synchronization clusters play a central role in epilepsy,and may activate the onset areas and contribute to the spreading of epileptiform activity.Yanping Sun Yuqiang Song Hongjin Ren Haifang Zhu Yanning Wang Xiaoli Li Wenjing Yan Yuping Wang 2022Acta Epileptologica2022,5,4:1

20Numerical Simulation of the Impact of Urban Non-uniformity on Precipitation显示文摘To evaluate the influence of urban non-uniformity on precipitation, the area of a city was divided into three categories(commercial, high-density residential, and low-density residential) according to the building density data from Landsat satellites. Numerical simulations of three corresponding scenarios(urban non-uniformity, urban uniformity, and non-urban) were performed in Nanjing using the WRF model. The results demonstrate that the existence of the city results in more precipitation, and that urban heterogeneity enhances this phenomenon. For the urban non-uniformity, uniformity, and non-urban experiments, the mean cumulative summer precipitation was 423.09 mm, 407.40 mm, and 389.67 mm, respectively. Urban non-uniformity has a significant effect on the amount of heavy rainfall in summer. The cumulative precipitation from heavy rain in the summer for the three numerical experiments was 278.2 mm, 250.6 mm, and 236.5 mm, respectively. In the nonuniformity experiments, the amount of precipitation between 1500 and 2200(LST) increased significantly. Furthermore, the adoption of urban non-uniformity into the WRF model could improve the numerical simulation of summer rain and its daily variation.Yuqiang SONG Hongnian LIU Xueyuan WANG Ning ZHANG Jianning SUN 2016Advances in Atmospheric Sciences2016,33,6:1
