The results extend those of autonomous systems to case for no autonomous systems . 4 . the stability and the existence of periodic solutions for ecological systems of reaction - diffusion type are discussed by using of smoller invariant domains principle liapunov functional method comparison principle and fixed point theorem 四、研究了用偏微分? ?积分方程描述的生态系统平衡位置的稳定性、渐近稳定性及周期解的存在性、稳定性,采用smoller不变区域原理、比较原理,不动点原理及liapunov泛函方法。
More recently he is researching in robots for service and entertainment purposes , such as a wearable robot , a medical diagnose robot and smart toys . he has also made contributions to modeling and transfer of human control strategy to autonomous systems and implemented in the world first autonomous land vehicle that drove across the american continent in 1997 他在智能控制理论上作出过许多贡献,例如,他所领导研发的对车辆驾驶技能的实时检模的系统,已成功用于世上第一辆横跨美洲大陆的无人自动车。
Also according to the basic solution matrix , hopf bifurcation of is investigated by creating subsequence functions , the measure of which differs from that of autonomous system . in the paper i apply myself to seek out a new idea to investigating heteronymous system that is no longer stickled in autonomous system 同样以这个基本解方阵为依据,本文接着研究二维周期系统的hopf分支,所用方法是构造后继函数法,但在具体构造方法上,与自治系统的hopf分支不同,本文致力于探索一种不再拘泥于自治系统的,研究非自治系统hopf分支的新思路。
Stsc does not only reduction statistical performance of multi - hops paths but also decrease estimation of upper bound of traffic delay and tail distribution . we also present generalized integrated service model ( cis model ) that founds bandwidth brokers in autonomous systems ( as ) that support traffic aggregating and traffic tagging . thus as are able to work under hybrid mode , so cis model is more adaptive to integrated data communication in broad bandwidth ip network 本文还提出了广义集成服务模型,通过在支持通信量聚合和标记的自治域中设定带宽代理和在网络边界实施面向应用通信量特征的分类机制,使得自治域能够在混合模式下工作,从而能更好地适用于宽带ip网络中的综合数据通信。
On the basis of analysis on the problems and elements which are interrelated with each other , a solution was put forward form the writing , that is to enable the community of xigang district to develop faster , you must establish a new type community autonomy concept , renew the autonomous system , perfect its organizational system , autonomous system and improve its service level , we should try to create more favourable conditions to make profit - making and non - profit making organizations play even greater role 在综合分析存在的问题和制约因素的基础上,本文提出解决问题的对策,即要加快西岗区社区自治建设,就必须树立新型的社区自治理念,创新社区自治体制,建立完善的社区自治组织体系,健全社区自治制度,提高社区服务的层次和水平,并积极创造条件发挥社区非营利组织和社团组织的作用。
