The ordinary spectrum is restricted in its applications, since it based on the second-order moments (auto- and cross-covariances). Alternative approaches to analysis have been investigated other measures of dependence. One such approach was developed for univariate time series by authors this paper using local Gaussian auto-spectrum auto-correlations. This makes possible detect structures that ...

For seismic resistant design of critical structures, a dynamic analysis, based on either response spectrum or time history is frequently required. Due to the lack of recorded data and randomness of earthquake ground motion that might be experienced by the structure under probable future earthquakes, it is usually difficult to obtain recorded data which fit the necessary parameters (e.g. soil ty...

A review of previous studies shows that there are two general views on how to determine demand in structures through incremental nonlinear static analysis. In the first view, multi-modal methods are used to determine demand in structures. In this view, the applied load pattern is applied to the structure according to the shape of each vibration mode, assuming that the structure deformation foll...

a more detailed analysis is made of the energy spectrum of the diffuse component of extragalactic gamma rays over the range of 0.3- 10 gev, obtained fromthe egret instrument at the compton gamma ray observatory. the derived excess energy spectrum of high galactic latitude, b > 60°, using intercept method shows that it is correlated with virgo cluster (over lsr) and average virgo intensity is ab...

The Hartley transform, a real-valued alternative to the complex Fourier transform, is presented as an efficient tool for the analysis and simulation of earthquake accelerograms. This paper is introduced a novel method based on discrete Hartley transform (DHT) and radial basis function (RBF) neural network for generation of artificial earthquake accelerograms from specific target spectrums. Acce...

Abstract Purpose: Autism Spectrum Disorder (ASD( identified via deficit of social communication, stereotyped movements and limited interactions. Postural instability is common in children with autism spectrum disorder. The purpose of this study is the effects of 8 weeks core stability training on trunk endurance in boys with autism spectrum disorder. Methods: The research subjects include ...
