Data streaming applications, usually composed of sequential/parallel data processing tasks organized as a workflow, bring new challenges to workflow scheduling and resource allocation in grid environments. Due to the high volumes of data and relatively limited storage capability, resource allocation and data streaming have to be storage aware. Also to(More)
Learning evaluation is an effective way to ensure the quality of online education. However, most of online learning evaluation models are not fully consider the characteristics of online learning. This paper, from the view of the characteristics of online learning, establishes an index system of evaluation of the online learning's effect. Besides, weight of(More)

11 We have developed a new method to analyze the power law based non-Darcian flow toward a well in a confined aquifer with and 12 without wellbore storage. This method is based on a combination of the linearization approximation of the non-Darcian flow equation 13 and the Laplace transform. Analytical solutions of steady-state and late time drawdowns are(More)
