In this paper, we present a general model for predicting the fatigue behavior for any stress level and amplitude using the exponential model. Based on the W\"ohler field for fixed stress level, a compatibility functional equation enables us to derive the general model with eight parameters. The problem of parameter estimation is then

EDAs guide search by building and sampling an explicit probabilitic model of high-quality solutions. EDAs can solve broad classes of hard problems scalably, often in low-order polynomial time. But scalable performance is sometimes not enough.

Results on multiple orthogonal polynomials will be surveyed. Multiple orthogonal polynomials are intimately related to Hermite–Pad e approximants and often they are also called Hermite–Pad e polynomials. Special attention will be paid to an application of multiple orthogonal polynomials and to analytic theory of two model families of general multiple orthogonal polynomials, referred to as Angel...

There is a close analogy between empirical distributions of i.i.d. random variables and normalized spectral distributions of widesense stationary processes. Herein we make use of this analogy to develop nonparametric comparisons of two spectral distributions and nonparametric tests of stationarity versus change-point alternatives via spectral analysis of a time series. © 2006 Elsevier B.V.

We formulate as a deconvolution problem thecausalhoncausal non-Gaussian multichannel autoregressive (AR)parameter estimation problem. The super exponential aljporithmpresented in a recent paper by Shalvi and Weinstein is generalizedto the vector case. We present an adaptive implementation that isvery attractive since it is higher order statistics (HOS) based b u t doesno...

one of the most important economic factors is potential output. in macroeconomic models and structural studies, the estimation of potential output is necessary for projections and analyzing policy performances. there exist several methods for estimating potential output. meanwhile, its estimation is a difficult and complicated matter. empirical studies and researches show that using various tec...
