Hierarchical tree queries mechanism in relation database system Natural Variation and Improved Variety selection of Catalpa 关系数据库层次树查询机制浅析楸树自然变异与良种选择
A new complex hierarchical structure, Group Cluster, is firstly proposed. Expanded from traditional tree structure, the Group Cluster can illustrate the complex system. 独创性地提出了复杂的层次式协作系统结构&群簇,对传统的树型层次结构加以扩充,使其能够描述由多个协作群体组成的复杂大系统(群体的群体)。
In real-time rendering phase, hierarchical visibility culling and optimized tree traversal efficiently improve system integral performance. 实时绘制阶段,层次可见性裁剪以及优化的树遍历提高了系统的整体性能。
Feature Hierarchical Tree Representation of the Self-Embedded Waveform and a Waveform Parsing System 自嵌套波形的特征层次树表达及波形分类系统
This paper first discusses the representation scheme of robot in computer and presents a hierarchical tree structure which can be used as the managing manner for the intelligent robot mechanism simulation system. 探讨机器人的计算机内表示,提出一种树层次模型作为智能机器人机构仿真系统的管理方式;
Adopting centralized and hierarchical tree and replacement algorithms based on visiting rate, current cache management proposals cannot efficiently utilize cached video segments in user end-systems and increase system service capacity. 由于当前的P2P点播缓存管理机制多采用集中式或层次树形的缓存管理,以及基于访问热度的淘汰算法,不能高效地利用用户节点缓存资源和提高点播系统服务能力。
