The statistical errors in the estimated correlation function matrix for operational modal analysis
TL;DR: In this article, it is proven that the estimated correlation function matrix is a Gaussian stochastic process and that the envelope of the modal correlation function is Rice distributed, which causes the tail region of the correlation function to become erroneous.

Simple model for turbulence intermittencies based on self-avoiding random vortex stretching
TL;DR: A bridge between polymer physics, self-avoiding walk, and random vortex stretching is established which may help to obtain new insights on the topic of statistics of intermittencies in homogeneous and isotropic turbulence.
Journal ArticleDOI
Earthquake motion input and its dissemination via the internet
TL;DR: The user community for this research is both academic researchers and practicing engineers who may use the seismic input generated by the synthesis techniques developed under this task for a variety of applications, including ground motions for scenario earthquakes, for developing fragility curves and in specifying ground motion input for critical facilities located in the eastern U.S.
Journal ArticleDOI
Nature and origin of sporadic E regions as observed at different hours (over Calcutta)
TL;DR: In this paper, the results of measurement on the variation of reflection co-efficient of the sporadic E echoes and of the statistical study of the variations of amplitude of the same, carried out, over a period of 8 months (March to October, 1952) at the Ionosphere Laboratory of the University of Calcutta.
Journal ArticleDOI
Comparison of methods for calculation of the wave envelope
TL;DR: Different methods for computing of the Hilbert transform are reviewed and discussed and statistical characteristics of the wave envelope determined by different methods are compared with the theoretical ones.
