Compared with the interior design activities, the furniture is one of the important factors in the process of the interior decoration. The choice of the appropriate furniture not only can effectively improve the quality of the interior design activities, but also can fully meet the specific application needs of the people. This paper starts from the analysis of the specific requirements on the design and production of the modern furniture. And combined with the analysis of the specific characteristics and the connotation of the design styles of the furniture in the Ming Dynasty, the author further explores the specific influence of the design styles of the Ming Dynasty furniture on the modern furniture.展开更多

With the deepening of the concept of green environmental protection, green building, as a new design concept, has sprung up, which has effectively promoted the development of new construction industry. As a new concept of environmental protection, green building has also been improved and adjusted in industrial buildings and applied in the process of architectural design to realize that the design results have the characteristics of ecological environmental protection and realize the strategy of sustainable development. Green building has now become the inevitable trend of the development of the construction industry.展开更多

First the genetic algorithm (GA) was adopted for recognizing the material parameters. Then according to the even design idea, the suitable calculation scheme was confirmed, and FEM was used for calculating the springback. The computation results were compared with experiment data, the difference between them was taken as source data, and a new pattern recognition method of DM called hierarchical optimal map recognition method (HOMR) is applied for summarizing the calculation regulation in FEM. At the end, the mathematics model of the springback simulation was established. Based on the model, the calculation errors of springback can be controlled within 10% compared with the experimental results.展开更多

Its trend is gradually changed from client to web, and so many people start to research the 3D graphics engine technology on the web. WebGL and HTML5 rise in recent years and WebGL solves two problems of interactive 3D application on the web perfectly. Firstly, it implements the interactive 3D web application by JavaScript without any browser plug-in components. Secondly, it makes graphics rendering using the underlying graphics hardware, which is united, standard and cross-platform OpenGL interface. However, it is very difficult for 3D application web programmer to understand multifarious details. Therefore, a 3D engine based on WebGL comes into being. The paper consults the existing 3D engine design idea, architecture and implementation experience, and designs a 3D graphics engine based on WebGL and Typescript.展开更多
