e-Science and e-Research is about supporting collaborations especially those that cross administrative boundaries. Typically this is achieved through establishing virtual organizations (VOs) where several institutions and individuals wish to contribute resources for their mutual interest, e.g....

A key problem in time series prediction using autoregressive models is to fix the model order, namely the number of past samples required to model the time series adequately. The estimation of the model order using cross-validation may be a long process. In this paper, we investigate alternative...
