Bistable Auxetic Metamaterials (BAMs) are a class of monolithic perforated periodic structures with negative Poissons ratio. Under tension, a BAM can expand and reach a second state of equilibrium through a globally large shape transformation that is ensured by the flexibility of its elastomeric base material. However, if made from a rigid polymer, or metal, BAM ceases to function due to the inevitable rupture of its ligaments. The goal of this work is to extend the unique functionality of the original kirigami architecture of BAM to a rigid solid base material. We use experiments and numerical simulations to assess performance, bistability and durability of rigid BAMs at 10,000 cycles. Geometric maps are presented to elucidate the role of the main descriptors of BAM architecture. The proposed design enables the realization of BAM from a large palette of materials, including elastic-perfectly plastic materials and potentially brittle materials.

Today, high technology is transforming traditional industry. The science, suitable measuring technique and data application method are the basis of large-scale manufacture realizing, which not only meet individual consumer demand, but also are meaningful to raise the economic efficiency and reduce production cycle of custom-made. Custom-made enterprise always has its own contact measuring method and mechanism, which uses uniform size clothing to wear or measurement by manual re-confirm to obtain data.The efficiency of this method is low and its accuracy is poor. But non-contact measuring method has problems in application of equipment and can not completely replace manual operation. How make manual measuring method and laser measuring instruments work together to get data is the demand of practical management and production improvement in enterprise, but there is no data standard between the two methods. This research based on national size standard and professional normative measuring method, and used manual and three-dimensional laser measuring ways to collect sample data in identical situation. Under designed data standard, the research used mathematical statistics to analyse data, and then made comprehensive assessment in aspects of instrumental stability and data correlation. This paper is the case of practical application, among which used to study the tolerance range of the standard data was initial issue (sci-tech novelty report was attached).

In the era of mass production, bulk and individual customizing is the ultimate purpose of the clothing processing. Now, how to make the customized body dimensions generated automatically is the foundation of Agile Manufacturing. The allowance of clothes can be provided according to the style and size of the clothing, and the function of mapping the human dimensions to measurements is a part of The Clothing CAD system .This paper introduced the detail of design and implement on the demand of the system which is made up of two parts. The first part of the system can classify the body dimensions according to diffferent criteria; when the body dimensions and the clothing style are fixed ,the second part will search in the Expert Knowledge database, and finally, the most optimalizing allowance of clothes is given. With this system, personalized customization of garment will come true under the condition of volume-produce; it will not only improves the efficiency, but also increases the accuracy of the customization.

As the Internet infrastructure gradually improved, electronic commerce based on Internet is also beginning to flourish. Colleges and universities is mainly to gather the youth, occupies an important position in the Internet, so the development of electronic commerce has a good potential in Colleges and universities. In recent years, the campus e-commerce with its unique mode of rapid rise, the campus electronic commerce mode of inquiry and analysis, provide a theoretical basis for the development of the campus e-commerce.

As the internet penetrates into all spheres of society gradually, network information technology is affecting all areas of society in a unique way. College students are an important group of Network User. In the network environment, the individual qualities, career pathways, career scope, business conditions about students have undergone great changes. Networks are becoming an important carrier for students to broaden employment channels, change the passive situation in the job market. This paper discusses the science construction of students’ employment network system in an angle of the characteristics and advantages of college students online employment, aiming at taking full advantage of Networks to promote the graduate employment, elevating employment information network to a new height, thereby increasing the employment rate of university students
