Internet of things (IoT) is an important part of the new generation of information technology; the name suggests that IoT is the internet of material connecting to material.
The clients exchange their information and communication between materials to any other materials.
Knowledge Engineering.
Knowledge Engineering was first proposed by the artificial intelligence expert EA Feigenbaum, it mainly includes three aspects of knowledge acquisition, knowledge representation and use of knowledge and treatment.
The use of knowledge and treatment is the third key factors of knowledge engineering, it consist mainly of reasoning, search, knowledge management and maintenance, matching and identification.

With continuous development of the structural engineering, a perfect theoretical foundation and construction means is the key to its development.
Considering the security need of prestressing curved beam’s tendon connection, attention should be paid not only to its materials and mechanical properties, but also to the convenience of construction.
The scientific and favorable technical guidance can be provided for actual engineering of the external prestressing.
Engineering Application With the vigorous development of engineering technology, requirements of the structure bearing are also gradually increase.
In general, prestressing steel can be used as materials of high-strength force, and the tendon role can offset part of the load internal force.

Due to their unique properties, auxetic materials have been extensively investigated for load bearing applications including in biomedical engineering and aircraft structures.

Based on the grey relation analysis of ecological composite wall seismic performance research Yin Zhang1, a, You Han1,b and Shuai Liang1,c 1School of Civil Engineering, Xi'an University of Architecture and Technology, Shanxi, Xi'an, 710055, China azhangyyt@xauat.edu.cn, bhanyou_good@126.com, c404507026@qq.com Keywords: Grey correlation; Ecological composite wall; Seismic performance; Key parameters.
Introduction The ecological composite wall structural system [1] is a kind of product ,which is adapt to the wall materials innovation of our country.
The main characteristic of it is the using of new material, new structure and new technology.
Discuss four kinds of the ecological composite wall bearing capacity of the ecological composite wall with standard curve, the relationship between the selection so that more conducive to the performance of the structure wall body construction, has guiding significance for practical engineering.
For practical engineering problems for flexible collocation, the specific requirements for selecting a reasonable design and construction of the ecological composite wall structure.

Application of a very wide range of engineering and construction of concrete beam, generally by the concrete and steel components, plays an important role in civil engineering.
Introduction Steel Reinforced Concrete (SRC) is -steel and concrete in a certain structure and connection ways of combining, [1] structure form a better performance than the two kinds of materials, the structure can make up for their shortcomings, is a commonly used building materials in civil engineering.
The bonding mechanism analysis. materials will occur deformation, accompanied by both, the deformation of the material produces sliding phenomenon between [5], the bearing capacity is greatly reduced, so want to find a way to increase the cohesive action between steel and concrete.

A material selection criterion for hot-stamping dies Yongsheng Ye1,2, Zhongde Shan 1,#, Baoyu Wang 2, Chao Jiang 1, Bailiang Zhuang1 1 No.18 XueQing Road HaiDian district, Beijing, China, State Key Laboratory of Forming Technology & Equipment 2 No.30 XueYuan Road HaiDian district, Beijing, China, School of mechanical engineering University of Science & technology Beijing # shanzd@cam.com.cn Key words: Hot stamping; Hot-working die steel; Die material; Material selection formula Abstract: Hot-stamping technology applies hot-stamping dies to the forming and quenching of austenitized high-strength steel plates to produce super-high-strength parts.
However, since the material performance requirements of hot-stamping dies have not been standardized, and special die materials have not been developed, the choice of materials is based on improving the safety coefficient, which leads to material waste and increased costs.
