In this paper, we extend Bai and Perron’s (1998, Econometrica, p.47-78) framework for multiple break testing to linear models estimated via Two Stage Least Squares (2SLS). Within our framework, the break points are estimated simultaneously with the regression parameters via minimization of the residual sum of squares on the second step of the 2SLS estimation. We establish the consistency of the...

This paper proposes two new weighting schemes that average forecasts using different estimation windows to account for structural change. We let the weights reflect the probability of each time point being the most-recent break point, and we use the reversed ordered Cusum test statistics to capture this intuition. The second weighting method simply imposes heavier weights on those forecasts tha...

Besides achieving an optimal scheduling generator, the operation safety of generator itself needs to be focused on. The development virtual visualization a capability curve simulation visualize condition is proposed in this paper. In paper, neural network applied redraw original generator’s curve. can simulate operating considering limitation constraints on various elements generator. Furthermo...

Abstract In order to break through the traditional von Neumann architecture of computing and memory cell separation speed up speed, it is necessary realize in computing, memristor an excellent carrier computing. Then, development, principle, characteristics application prospect are briefly introduced, characteristic curve obtained by simulating model memristor. The principle explained more intu...

A one-dimensional model framework of unsteady free-surface flow through a blocking-drag region is developed, tested, and applied to understand the dam-break past rectangular building. This achieved by studying steady-state, adjustment response region. Three steady regimes are identified based on Froude number upstream downstream region: subcritical state, choked state with subcritical-supercrit...

in the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. in this study, a series of compression tests were simulated using abaqus software. in this study, it has been employed the taguchi method to design experiments by the factor...
