In this paper, a method to determine the "stability" probability p_1~T of the network points of repeated relative gravity surveys is derived, and based on this, a method for calculation of information entropy of that network is given. With these methods, some information entropys of repeated relative gravity before and after some earthquakes, such as Haicheng earthquake (Ms=7.3) in 1975, Tangshan earthquake (Ms=7.8) in 1976 and Heze earthquake (Ms=5.9) in 1983, are calculated. And the characteristic...

Based on the present probabilistic eigenvalue studies, this paper presents a hybrid algorithm using moments and cumulants of random variables. Uncertainties considered are system multi operating conditions derived from operating curves of nodal loads and generations. By means of the first and second order eigenvalue sensitivity representation with different approximation, moments and cumulants of eigenvalues are determined from the statistical nature of nodal voltages and nodal injections. Probabilistic distributions and stability probabilities of critical eigenvalues are calculated from the Gram Charlier series. In the proposed hybrid algorithm, random variables can have arbitrary distribution. Dependencies among random variables, interaction between expectations and covariances, as well as the correction of covariance to expectation are all considered.
