Abstract
Several scientific areas benefits from the research methods empowered by computers in an e-Science paradigm. One of the major issues in this context regards to the underlying infrastructure interoperability. This work provides an e-Science environment named Sentinel to support scientists in their research in a cloud environment using any enabled device to access the web. The web portal allows parameterization, initialization and monitoring of experiments transparently from net infrastructure. As an illustration, techniques as such as Detrended Fluctuation Analysis (DFA) and Gradient Pattern Analysis (GPA) will be discussed in the context of a time series analysis application to understand seemingly unpredictable behaviors as extreme events in space physics. The EMBRACE (Brazilian Space Weather Program) program was chosen as a DFA case study for the knowledge and prediction of different phenomena that directly affect human activities, such as solar activity, magnetic storms and ionospheric storms, they have great importance for the well being of society. Furthermore, new applications can be uploaded to Sentinel easily empowering researchers to manage their scientific work-flows. It is hoped that this work may contribute for a friendlier environment for e-Science users.
