简介:在这份报纸,一个分布式的一致协议在一般固定指导拓扑学下面与测量噪音为分离时间的单个整数的多代理人系统被建议。变化时间的控制获得令人满意随机的近似条件被介绍稀释噪音,这样靠近环的多代理人系统是内在地一个线性变化时间的随机的差别系统。然后,吝啬的方形的一致集中分析基于Lyapunov技术被开发,并且Lyapunov函数的构造特别不要求为二次的Lyapunov功能的存在假定的典型平衡网络拓扑学条件。因此,建议一致协议能对更一般的联网的多代理人系统适用,特别地当在代理人之间的双向或平衡的信息交换没被要求时。在建议协议下面,每个代理人的状态在吝啬的平方收敛到其数学期望是起始的状态珍视的代理人的加权的一般水准的一个普通随机的变量,这被证明;同时,随机的变量变化被围住。
简介:在这研究,离氨酸被介绍进apatitewollastonite玻璃的表面陶器(AW-GC)走反应在二改进它的cytocompatibility过程。第一,离氨酸与N连接了--(aminoethyl)--由酰胺组有约束力的共有原子价的aminopropyltrimethoxysilane(A-1120)。第二,lysine-functionalizedA-1120通过包含一个共有原子价附件的silanization反应在AW-GC的表面上被扔。FTIR系列显示离氨酸成功地被使不能调动到AW-GC的表面上。表面的Bioactivity修改了AW-GC被模仿的身体液体(SBF)调查,并且在里面vitrocytocompatibility被coculturing与人的osteosarcoma房间MG63评估。当hydroxyapatite免职的模式被改变时,结果证明在修改材料上形成的hydroxyapatite层的过程类似于AW-GC。MG63细胞的生长证明与离氨酸修改AW-GC表面提高细胞粘附和增长。
简介:摘要院针对智能化群体决策,结合Agent技术提出了基于多Agent的智能决策支持系统模型。分别对该模型的交互层以及智能决策层中的各Agent进行了描述,并说明了资源层中各库的功能。该系统通过黑板控制Agent进行Agent之间地协调,有助于多个Agent协同求解大规模复杂问题。
