Dimensional reduction of 3D building models using graph theory and its application in building energy simulation

Since the various people involved in the design process for a building project tend to hold conflicting views, this inevitably leads to a range of disparate models for planning and calculation purposes. In order to interpret the relevant geometrical, topological and semantical data for any given building model, we identify a structural component graph, a graph of room faces, a room graph and a relational object graph as aids and explain algorithms to derive these relations. We start with a building model by transferring its geometrical, topological and semantical data into a volume model, decomposing the latter into a so-called connection model and then extracting all air volume bodies and hulls of the model by means of further decomposition into elementary cyclic connection components. The technique is demonstrated within the scope of building energy simulation by deriving both a dimensionally reduced object model required for setting up a thermal multizone model and a geometrical model for defining single or multiple computational fluid dynamic domains in a building together with incidence matrices correlating these models. The algorithm is basically applicable to any building energy simulation tool.

Industry evaluation of the Requirements Abstraction Model

Software requirements are often formulated on different levels and hence they are difficult to compare to each other. To address this issue, a model that allows for placing requirements on different levels has been developed. The model supports both abstraction and refinement of requirements, and hence requirements can both be compared with each other and to product strategies. Comparison between requirements will allow for prioritization of requirements, which in many cases is impossible if the requirements are described on different abstraction levels. Comparison to product strategies will enable early and systematic acceptance or dismissal of requirements, minimizing the risk for overloading. This paper presents an industrial evaluation of the model. It has been evaluated in two different companies, and the experiences and findings are presented. It is concluded that the requirements abstraction model provides helpful improvements to the industrial requirements engineering process.

我国纺织业展会的知识产权保护

近年来,我国各类纺织专业展会盛事不断,这些展会覆盖了纺织行业的整个产业链：纺纱、织布、服装、印染、家用纺织品、产业用纺织品、纺织化学用品和纺织机械等。但由于我国会展业仍处于起步阶段,与发达国家相比,管理体制尚不完善,特别在展会知识产权保护方面存在一定差距,导致了纺织会展业诉讼纠纷不断。如何加强纺织业展会的知识产权保护俨然成为中国纺织业界不可忽视的一个重要问题。

地球重力场模型在高程控制网中的应用

不同地球重力场模型的优选及不同拟合方法的合理选择是GPS高程转换所需考虑的关键问题。随着以卫星重力梯度为主要观测值的GOCE重力卫星的发射成功及其相关重力场模型的推出,地球重力场模型的精度及分辨率有了较大提高,有必要将其应用于GPS高程转换的研究。本文提出了用目前具有较高精度的SGG地球重力场模型来代替以往较低精度地球重力场模型的策略,计算分析了这种模型解算全球高程异常的精度,并将这种模型应用于”移去一拟合一恢复”法的GPS高程转换中,使GPS提供真正意义上的三维坐标。
