Abstract: The FEM model of the body and acoustic cavity are created, and the acoustic-structure coupled system is built up,and the SPL(sound press level) of points corresponding to the drivers ear and passengers ears were calculated using software LMS.virtual.lab. And there are several relatively noticeable acoustic pressure peaks around 60Hz, 102Hz, 120Hz and 168Hz. The maximum noise value was calculated by using the method of ATV method, several suggestions are advised to decrease the vehicle interior noise so that the vehicle ride comfort could be improved.

Abstract: Transportation system is a typical economic system for its operation and structure optimization result from the comprehensive functioning of numerous dynamic and joint driving forces. To accurately grasp the genuine core of the basic principle and operational characteristics of structure optimization of the transportation system is to clarify the dynamic problems of it. The principles to which the characteristic and function and formulation of the transportation system complies are systematically analyzed in this paper. And the external and internal factors of structure dynamic optimization of the transportation system are researched, and further depiction is discussed from four aspects: acquirement, technology, fund, quality and environment respectively, and the source originated from optimization dynamic of transportation system, process of dynamic transmission, influencing factor of dynamic function based on the behavioral function of economy-main-body, which is of vital significance and meaning to the research of the mechanism and principle of the structural optimization of the transportation system.

Abstract: This paper is based on the high-precision temperature control system and focuses on the realization of the serial communication module.

Abstract: In the history, the Grand Canal bore the functions of shipping, water conservation and landscape and created the society, economy and culture of Suzhou. The change of Suzhou development strategy requires Canal function to change accordingly. From the aspect of Canal function, this article makes an analysis of the development interactive relation between the Canal and Suzhou city, study the new requirement of Suzhou city development on the Canal, and raise a new development strategy of Canal Suzhou section.

Abstract: A new type of polycarboxylate superplasticizer with high dispersibility was synthesized by the method of free radical polymerization and the hydrothermal reaction. The synthetic process optimized the influencing factors of reaction had been discussed, including proportion of acid and ether, reaction temperature, initiator concentration, heat preservation time and additive. The dispersibility of new product was superior under the condition of low water/cement ratio, testing by gel permeation chromatography and C60 self-compacting concrete. The new product had already been used in Tianjin Goldin 117 Mega Tower project. The performance of C70 fresh mixed self-compacting concrete, which was added with new product, was very excellent in Tianjin Goldin 117 Mega Tower project, and was satisfied with the design code for high-strength self-compacting concrete in China. It is possible to realize industrial production.

Abstract: Recent studies [1, 2] were devoted to author's efforts in formalization of conceptual design process based on vast data in mechanical design accumulated over years. The suggested novel method of conceptual design is implying direct dependence of function and a mechanism intending to implement the challenged function, considering a wider interpretation for both categories of mechanism and function. Main aspects of this method relate to formalization of both mechanism and function, formatting of design pages for tracking the concept design process, formalization of synthesis and analyze tools and formation of design models serving different design targets. Effectiveness of those formalization tasks is based on development and usage of specific graph and matrix based mathematical engine, enabling compact presentation of various aspects of conceptual design method. The current study is aiming to disclose the specific conditions of formalization for reconfigurable as categories widely used in mechanism synthesis and analyzes. Formalization of reconfigurable mechanisms will categories is contribute a lot in effectiveness of organization of concept design. An example from design experience is considered to confirm the validity of suggested formalization approach for the case of reconfigurable mechanisms.

Abstract: The national library is a source of knowledge location, its construction is very important. Modern libraries are required information and intelligence, but the library as a whole, in the process of building, not only to focus on its management system, but also to pay attention to its functional interior design and interior decoration. This paper presents an intelligent library management and internal functions and decoration materials design, not only the internal functions of the library design were studied, also raised the standard interior materials, and designed a complete intelligent management system.

Abstract: The sequencing specification defines an interoperable method for representing the intended behavior of an authored learning experience such that any Learning Management System (LMS) will sequence discrete learning activities in a consistent way. At present, in the sequencing specifications, the intended Sequencing Strategies is encoded one by one in the XML file, causing the redundancy of sequence data. This paper presents an innovative function mechanism to design learning sequencing. This mechanism adds two categories, a function element and a function-call element, into the IMS Content Package Information Model. The function element is used to design a reusable sequencing component with an interface of parameters, while the function-call element is used to repeatedly call the function element by transferring various actual parameters. This method improves the design environment of the learning sequencing and effectively reduces the redundancy of the learning sequencing in a content package.

Abstract: Current tourism-led tertiary industry achieved remarkable development and achievements. In order to make better use of the natural geological resources, local governments adopt local characteristics as a guide to invest in tourist attraction construction to promote local economic development. However, due to the lack of scientific and technical conditions, tourist attraction construction is only confined to the planning and design of major landscape regions, rather than taking into account the query needs of tourists during the tour. Under this background, this thesis first of all makes an introduction to geographic navigation system function, and then proposes the function design of tourist attraction geographic navigation system and application of GPS technology to tourist attraction navigation, so as to assist the further study.

Abstract: This thesis from the perspective of building group space, through the in-depth analysis and expansion of evaluation elements and operating framework in the book Assessing Building performance, extracted building groups space performance evaluation index system: functional indicators. The land function mixture and analysis of accessibility constitutes the function evaluation. Finally introducing the basic data of Wuhan Optics Valley Software Park, mainly about its spatial parameters, has deeply analyzed and demonstrated by using technique. To provide reference of the later design and transformation of similar industrial park building group space.
