摘要：
Recently, the computational requirements for large-scale data-intensive analysis of scientific data have grown significantly. In High Energy Physics (HEP) for example, the Large Hadron Collider (LHC) produced 13 petabytes of data in 2010. This huge amount of data is processed on more than 140 computing centers distributed across 34 countries. The MapReduce paradigm has emerged as a highly successful programming model for large-scale data-intensive computing applications. However, current MapReduce implementations are developed to operate on single cluster environments and cannot be leveraged for large-scale distributed data processing across multiple clusters. On the other hand, workflow systems are used for distributed data processing across data centers. It has been reported that the workflow paradigm has some limitations for distributed data processing, such as reliability and efficiency. In this paper, we present the design and implementation of G-Hadoop, a MapReduce framework that aims to enable large-scale distributed computing across multiple clusters.

摘要：
The information technology based on computers is developing rapidly, which provides basis and possibilities for digital learning. So it is very meaningful to develop a digital learning environment to support present learning with the help of network technology, virtual reality technology and multimedia technology. In the basis of analyzing the users of instruction system, this paper has discussed detaily the design of the open digital-classroom system and its workflow. And the goal is that these studies are helpful to build a new completed digital environment for E-Education.

摘要：
With the development of the network and computer technology, the educational technology based on computer network is becoming popular worldwide. However, nowadayspsila distance education merely stays on the stage of Web-based courseware and one-way teaching, and it can not effectively support real-time classroom teacher-student interaction. This paper proposes a new interactive distance teaching and demonstration mode, which can allow the interaction between the teacher and the virtual scene as well as between the teacher and the student. We emphasize the design of the smart classroom that based on blending reality. In this paper, It shows the train of thoughts that how to integrate the virtual reality technology into distance teaching to help teachers show their teaching materials. We also present the method of that teachers interact on the object in the virtual reality.

摘要：
E-learning is the hottest point in the education. But the present status of its technology support is unoptimistic .In this paper it discussed a new system that used in the network distance teaching. First, the motivation of the blending-reality smart classroom is overviewed. Then it describes the system’s functions and frame as well as its work flow. At last the paper elaborates with emphasis the key technologies that involved in the system development.
