A decision theorem is given for the linear branch numbers and the difference branch numbers of the invertible linear transformations on F8×42,And a siuplified decision theorem is given for a specialinvertible linear transformation,namely the cyclic shift plus on F2.

This paper proposes a new method to model and predict network traffic based on fractional differencing and fuzzy-AR model.

Univariate forecasting methods are still used far more in practice, such as Fractional Differencing models, Structural models and Bayesian Forecasting methods.

The characteristic of the unitary auto correlation function of the fractionally differenced result of the random fractal signal is analyzed on the basis of the fractional difference equation.

A new method to model and predict network traffic based on multi-fractional difference and AR model was proposed in this paper.

Fast calculation on branch coefficient in protection relay setting and coordination;

In this paper the function and structure of relay setting on-line coordination system are presented,in which accurate fault calculation model is adopted and branch coefficient is no more introduced,so the computation accuracy is improved.

Different elements influencing calculation of line branch coefficient and sideline current addition coefficient are fault points,fault types and operating modes.

Moreover, the analysis has indicated that the asymptotic heuristic branching factor is same as the brute-force branching factor.

The branching factor of a regular search tree has a decisive effect on the time complexity of a search algorithm.
