Virtual Experiment Services

Abstract

There is increasing recognition of the need for laboratory experience that is through these experiences that students could deepen their understanding of the conceptual material, especially for the science and engineering courses. Virtual Experiment has advantages over physical laboratory at many aspects. Nowadays virtual experiments are mostly stand-alone applications without standard interface, which are difficult to reuse. Moreover it is a challenging for compute and data intensive virtual instruments to be reasonably responsive. In this paper, we propose a virtual experiment model based on novel grid service technology. In this model we employ two-layered virtual experiment services to provide cheap and efficient distributed virtual experiment solution. This model could reuse not only virtual instruments but also compositive virtual experiments. In order to reuse successfully-deployed virtual experiment, we advance a uniform schema to describe a virtual experiment plan and process.
