As a kind of socialization of investment tools, private equity funds originated in the U.S.100 years ago. In our country, the private equity funds have a shorter history. There is no formal official definition. it generated a pattern by itself, including private equity funds and venture investment company, industrial investment funds, investment companies, investment management companies, investment consultation companies, asset management companies, investment guarantee companies, trust. China private equity funds have been developing rapidly, it has its own features, but it also has many problems. That should be settled as soon as possible. © 2011 IEEE. Source

Currently 3D model animation has been widely used in film, television, games and other fields. The basic principle o 3D model animation is that the position of each vertex of the model will change in different time. It can be divided into Morph animation, Skeleton animation and Skinned Mesh animation. Skinned Mesh animation solves the problem of seams. And it is popular because of its realistic, flexible interaction effects. In the application background of three-dimensional e-learning platform, this article describes the principle of skinned mesh animation technology, and compares three kinds of key frame interpolation methods. We hope to improve the picture quality while increasing the run speed of Skinned Mesh animation. Meanwhile, the visual effects of the network teaching platform can be optimized. Source

Integral imaging is a promising technology for 3D imaging and display. This paper reports the 3D spatial-resolution research based on reconstructed 3D space. Through geometric analysis of the reconstructed optical distribution from all the element images that attend recording, the relationship among microlens parameters, planar-recording resolution, and 3D spatial resolution was obtained. The effect of microlens parameter accuracy on the reconstructed position error also was discussed. The research was carried on the depth priority integral imaging system (DPII). The results can be used in the optimal design of integral imaging. © 2013 Optical Society of America. Source

Teaching of e-commerce in higher vocational education must adapt to the demand of the social e-commerce development, highlighting the educational mode focusing on ecommerce technique and skill. E-commerce practical training teaching system in accordance with the characteristics of vocational education should be constructed. Comprehensive practical training teaching process sufficiently embodying characteristics of e-commerce vocational education of finance and economics as well as the items basing on positional typical task should be mapped out. © 2010 IEEE.

With the rapid development of the cloud computing and big data, many data center network are growing more large scale, and the number of servers is increasing at an exponential rate. In this paper, VCG (Vickrey-Clarke-Groves) mechanism was introduced into replica placement. Mapping from replica placement model to VCG mechanism was established and suitable payment function was designed. Data storage strategy is built on the distributed file system. In order to ensure the reliability of data storage further, GFS and HDFS both refer to the concept of replica of data block. This paper generally introduced replica strategy, and mentioned that the storage location of data replica is a key point of the research on replica technology currently. © 2015 IEEE. Source
