Let G=SU(2) and let \Omega G denote the space of continuous based loops in G, equipped with the pointwise conjugation action of G. It is a classical fact in topology that the ordinary cohomology H^*(\...

It is a complicated problem for the bottom-to-top adaptive conceptual design of complicated products between structure and function. Reliable theories demand to be found in order to determine whether ...
针对产品结构变型需求，结合面向对象方法中的框架表示和继承理念，提出了基础框架的概念。元件基础框架代表了功能相似产品元件共性的功能、结构及几何特性，基础框架解决了异构可变型元件的难以统一形式化表示的问题。提出了一种基于元件基础框架的结构变型设计方法，研究了基础框架构建关键技术。通过继承相同基础框架的异构零部件族模型变型实例的替换以及零部件模型自身的尺寸变型，实现产品结构与尺寸的复合变型。最后，将该方...
