Based on the ICMmethod,the discrete topological optimization problem about spot-weld's existence or not is transformed into the continuous optimization problem on[0,1].The optimization model is founded with maximizing the structural stiffness as objective and structural strength as constraints.The problem of multi-objectives and multi-constraints is transformed into the problem of single-objective and single-constraint with the K-S function.The displacement and stress are transformed into the explicit function of design variables with the Response Surface Methodology.The optimization model is solved with Sequential Quadratic Program.

基于ICM(Independent Continuous Mapping,即独立、连续、映射)方法,将焊点有无的离散拓扑优化问题转化为[0,1]区间上的连续优化问题;建立了以结构刚度最大为目标、结构强度为约束的连续拓扑优化模型;采用K-S函数将多目标和多约束问题转化为单目标和单约束问题;运用响应面方法将位移和应力转化为设计变量的显式函数,采用序列二次规划方法求解优化模型。

在二维空间中,分析了利用Allen区间关系对方法分别描述方向区域和常用的8大拓扑关系(disjoint,meet,overlap,cover,coveredby,contain,inside,equal)的不足,并改进了现有的方法。

A simple polynomial approach for A Class of nonlinear system modeling is presented. By this, the input-output data are firstly changed into [0, 1] by using topological homeomorphism conversion; then an initial polynomial model is selected. The parameters of polynomial model are estimated by using recursion least squares method. A final polynomial model is obtained by repeatedly estimating parameter and eliminating redundant terms.

After analyzing the merit and lack of 9I model, the main idea is proposed: to distill some basic topological relations from 9I model, of which the composite topological relations of complex objects are made up. In detail, the composite topological relationships between region and region, line and line, line and region are particularly discussed;(2)Analyze the characteristics and inner relations of cadastral features. According to the expressional model of complex topological relations, the author discovers the possible topological relations between parcels, parcel lines and parcel points. In addition, sum up the general topological relationship rules of cadastral data.(3) Then the topological relations model is extended to the spatio-temporal data. Time in cadastral database and change semantic are discussed. It's redefined that spatio-temporal topological relations is composed of time, location, status and event relation. Spatio-temporal topological relationships can be represented by extended 4I model. Taking cadastral parcels as example, there are different possible spatio-temporal topological relationships between parcels when they are extended, shrunken, split, merged or others. Thus, some deductions are drawn that, for example, if parcels have be coexisting for some time they are impossible to be overlapped. Furthermore, the parents of parcels alternated and their possible change types can be detected by their spatio-temporal topological relationships.(4) Before carrying out the experiment, the calculation method must be designed.

具体研究工作及成果如下:(1)根据点集拓扑理论中与拓扑空间相关的概念,本文对空间的点、线、面进行了重新定义,以区分对象的复杂性;分析了9I模型在表示简单对象方面的优点,以及在表达复杂对象上的不足,阐述了本文的研究思路和解决方案,并以复杂的面面、线线和线面为例详细探讨了复合拓扑关系的表达方法;(2)分析了地籍权属数据和地类数据的内涵、特点和要素之间的联系,根据复杂对象的拓扑关系表达模型,本文讨论了宗地、界址线、界址点之间,图斑、线状地物、零星地类之间可能存在的拓扑关系和形式化表达方法,归纳总结了地籍对象的拓扑关系满足的约束性规则;(3)将拓扑关系的研究延伸到时空领域,从地籍对象的时态性出发,本文阐述了地籍数据中时间的含义和变化语义描述的需要;从时间、位置、状态、事件等之间的拓扑关系方面,重新系统性地进行了时空拓扑关系的定义;研究了一维时间和二维空间的集成表达方式,以宗地、界址线为例,分析了变更前后不同时间区间里可能的拓扑关系,探讨了时空拓扑关系对时空变化操作类型和变化语义的推理方法和意义;(4)为实现空间拓扑关系的查询分析等应用,本文研究了空间拓扑关系的计算方法。

For single-attribute range queries in Armada, this thesis designs the single-attribute order-preserving naming algorithm Single_hash to assign adjoining ObjectIDs to objects with close attribute values based on the partition tree model, so that the objects can be published to the same or related peers in the P2P system. Then this thesis proposes the single-attribute range query processing algorithm PIRA, which can match the search paths of range queries to the underlying FissionE topology efficiently based on the forward routing tree to reduce the delay and message cost of range queries.
