... A well known problem with EOP prediction is that a prediction strategy proved to be the best for some testing period and prediction length may not remain as such for other period of time. In this paper we consider possible strategies to combine EOP predictions made using different analysis techniques to obtain a final prediction with the best accuracy corresponding to the least prediction error between input predictions. ... C2 ­ best previous prediction for given length. ...

... In our numerical experiments we have mainly considered two test objects provided by R. Hanisch and characterized by different types of brightness distribution; one of the objects simulates an elliptical galaxy and the other one a star cluster with size 512 512 and 256 256 pixels, respectively. ... The best performances in the restoration of the star cluster image are provided by the R-L algorithm and the LWPOS one; they give accuracies of 6%and 5%, respectively (see Table 1). ...

It was organized in the frame of the thematic year on the multiscale methods and modeling in biology and medicine organized by the Russian-French laboratory J.-V.Poncelet. ...

A very important stage in a story of formation of any new science is the shift from discussion of situation which are possible but do not occur in practice due to some reason to recognition of real phenomena of interest. ... We suggest to consider computer viruses as this new specific form of life which is coming in the contact with our form of life. ... Computer life has been created by human being, the role of independent evolution of computer viruses seems to be still negligible. ...

... trous Up: The discrete wavelet Previous: Introduction . Multiresolution analysis [ 25 ] results from the embedded subsets generated by the interpolations at different scales. ... In order to restore the original data, Mallat uses the properties of orthogonal wavelets, but the theory has been generalized to a large class of filters [ 8 ] by introducing two other filters and named conjugated to h and g . ... Figure: The filter bank associated with the multiresolution analysis . ...

Next: One example Up: No Title Previous: No Title . Wavelets are versatile tools of harmonic analysis. Because of their many uses, the word `wavelet' comes with different connotations (and different promises) to users in different fields. ... To pursue the analogy, one may wish to select from the data some contact surfaces with specific finish tolerances. the amount of information is then reduced by selection and/or by statistical means. ...

... Chapter 14. ... Data consist of numbers, of course. ... In the following sections, you will repeatedly encounter the following paradigm: § apply some formula to the data to compute a statistic § compute where the value of that statistic falls in a probability distribution that is computed on the basis of some null hypothesis § if it falls in a very unlikely spot, way out on a tail of the distribution , conclude that the null hypothesis is false for your ... 609 610 Chapter 14. ...
