This paper studies the secure and accurate clock synchronization problem for sensor net-works with time-varying delays and malicious attacks.A novel clock synchronization scheme based on the attack detection mechanism,attack compensation,and maximum conse
In this paper,an approximation-based event-triggered model predictive control(AETMPC)strategy is proposed to implement event-triggered model predictive control for continuous-time con-strained nonlinear systems under the digital platform.In the AETMPC str
湖南汝城位于华夏“多”字形构造带、南岭东西向构造带中部的交汇处,区内热水镇是中国中南六省最大的地热田,一般水温为91.5℃,最高98℃,异常面积3 km2.为深入查明汝城干热岩地热赋存条件及资源类型,该文在以往地热地质研究基础上,通过对区内地热资源分布、地温场、岩石热物性及放射性特征等,综合分析了汝城地区干热岩地质特征及干热岩地热资源成因,并总结分析了汝城区干热岩资源类型.研究表明,区内隐伏岩体发育,平均地温梯度达13.74℃/100 m,花岗岩生热率达3.13～14.86μW/m3,平均生热率为6.97
The problem of exponential module-phase synchronization of complex-valued neural net-works(CVNNs)with time-varying delay and stochastic perturbations was investigated.The model of CVNNs with time-varying delay and stochastic perturbations was considered.T
The g-SGD algorithm significantly outperforms the conventional SGD algorithm in ReLU neural networks by adopting the basis path set.However,how the inner mechanism of basis paths works remains mysterious,and the g-SGD algorithm that helps to find a basis
The study on how to identify influential spreaders in complex networks is becoming increas-ingly significant.Previous studies demonstrate that considering the shortest path length can improve the accuracy of identification,but which ignore the influence o
This paper investigates the set stability of probabilistic time-delay Boolean networks(PT-DBN)with impulsive effect.Firstly,using the algebraic state space representation,an equivalent stochastic system is established for PTDBN with impulsive effect.Then,
We study the equipment sharing problem where a group of food & beverage companies share the same equipment of a contractor and wish to have their processing tasks coordinated such that the total cost is minimized.The raw materials to be processed are peri
The optimal exponentials of thickness in the geometry rigidity inequality of shells represent the geometry rigidity of the shells.The author obtains that the lower bounds of the optimal exponentials are 4/3,3/2,and 1,for hyperbolic shells,parabolic shells
The problem of designing a passive filter for nonlinear switched singularly perturbed sys-tems with parameter uncertainties is explored in this paper.Firstly,the multiple-time-scale phe-nomenon is settled effectively by introducing a singular perturbation
