Many time-critical applications, such as emergency evacuation, demand decision-makers to make prompt decisions under time pressure. Therefore, it is essential to design an intuitive and interactive user interface to present critical information to users so that they can make effective decisions in time-critical situation. Using Ajax technology, this paper designs a GIS-based, flexible and interactive...
Since numerous large-scale scientific applications executed on grids are expressed as complex scientific workflows, workflow management has appeared as one of the most important service in grid environment in past few years. However, most of the management systems do not fully hide the complexity of the underlying orchestration language. Meanwhile, grid environment is dynamic when each scientist involves...
Computational Chemistry as a data-intensive application involves the geographically dispersed extraction of complex data information from very large collections of measured or computed data. And many chemists from different domains have to work together to explore, query, analyze, visualize and process large-scale heterogeneous data sets. Therefore, in order to address these challenges, we present...
Scientists are increasingly using scientific workflow environment to manage large data sets and execute experiments on distributed resources. Scientific workflows have become an important mechanism for scientists to combine scientific data management, analysis, simulation, and visualization tasks. However, most of the environments don't fully hide the complexity of the underlying orchestration language...
Scientific workflows are becoming increasingly important as a mechanism for orchestrating distributed resources such as computational devices, data, applications, and scientific instruments on the grid environment. BPEL is generally accepted as a de-facto standard for web-services composition. However, the lack of generic graphical interfaces that abstract the technical details for domain scientists...
