高效内存的R树索引
应用背景
知名的空间索引R树,这个是基于内存的实现,160000个MBR的r树构建时间为4秒
里面包含插入结点,删除结点,和查询结点,支持动态的树结构维护。
关键技术
R树结点插入insert();
R树结点删除delete();
R树索引搜索search();
注意:在插入和删除的同时需要考虑根节点的分裂与替换。

SIMPLE algrithm in Computational fluid mechanics
应用背景This application is to focus on the numerical methods in Computational Fluid Mechanics, dealing with aeronautics, hydraulics, heat and mass transfer etc. We konw fluids have the ability to transport matter and its propertities as well as transmit force, therefore fluid mechanics is a subject that is particularly open to cross fertilization with other sciences and disciplines of engineering. The subject of fluid mechanics will be highly relevant in domains such as chemical,metallurgical, biological and ecological engineering.关键技术
SIMPLE (Semi-Implicit Method for Pressure Linked Equations) algrithm is the principal numerical method to numerical simulate incompressible fluid flow, it can remove the difficults of fake pressure disturbance and neglecting specific pressure equation for incompressible fluid flow successful. The main thoughts and steps of SIMPLE algorithm are given in this application.
