This paper firstly summarizes and defines data grid models and the process of job scheduling, simultaneously analyzes the time and cost of job execution in the data grid. The job scheduling strategy influences the QoS of the data grid immediately and then proposes a design proposal of the job scheduling simulator of data grid based on a grid simulator named GridSim and introduces the architectu...

A very large-scale logic simulation engine "VELVET" has been developed VELVET is a vectorized event-driven simulator which can handle simultaneously both gate-level logic and Register-Transfer Level structure. VELVET can process simulation jobs two orders of magnitude faster than a conventional gate-level simulator. This paper describes how to realize such high performance, an algoritha for vec...

This article addresses how computer-based simulations may support conceptual learning in science education. The study investigates how these interactions unfold, and explores how it may inform design. The article reports on project-based learning in schools where four pairs of students from upper secondary school use a future climate simulator integrated in a web-based learning environment. Our...

In our experience, one of the most challenging aspects of conducting research using driving simulators is the postprocessing of simulator data, a process often referred to as data reduction. This step is necessary to produce various numeric measures that in turn are used for statistical analysis. Although commercial software packages can often be used to facilitate the process, such tools are n...

Biomass pyrolysis process from a drop tube reactor was modelled in plug flow using Aspen Plus simulation software. A kinetic mechanism for developed considering the recent improvements and updated schemes to account different content of cellulose, hemicellulose, lignin. In this regard, oak, beechwood, rice straw, cassava stalk biomasses were analyzed. The main phenomena governing are identified...
