The problem of known signal detection in Additive White Gaussian Noise is considered. In this paper a new detection algorithm based on Discrete Wavelet Transform pre-processing and threshold comparison is introduced. Current approaches described in [7] use the maximum value obtained in the wavelet domain for decision. Here, we use all available information in the wavelet domain with excellent r...
متن کاملIgnacio Vives Ponseti (1914-2009)
Ignacio Vives Ponseti developed a noninvasive method for treating congenital club foot in the US during the late 1940s. Congenital club foot is a birth deformity in which one or both of an infant's feet are rotated inward beneath the ankle, making normal movement rigid and painful. Ponseti developed a treatment method, later called the Ponseti method, that consisted of a series of manipulations...

siblings (with whom they have equal genetic similarity), etc. The conflicting heritability estimates fall nicely into place on this hypothesis, but do not and cannot converge on a single better estimate. The reason is that, once different figures for environmental similarity are required for different kinships, the heritability equations become underidentified; there are more unknowns to solve ...
متن کاملIgnacio Angelelli Predication Theory: Classical Vs Modern
This essay aims, first, at describing the conflict between the theory of predication (classical, Aristotelian) prevailing in philosophy until the end of the 19th century, and the theory arisen with the new logic (modern, Fregean). Three features characterize the preFregean period: 1) conflation of predication and subordination (extensionally: membership and class-inclusion), 2) conflation of id...
متن کاملpopulation genetics of gene function Ignacio
This paper shows that differentiating the lifetimes of two phenotypes independently from their fertility can lead to a qualitative change in the equilibrium of a population: since survival and reproduction are distinct functional aspects of an organism, this observation contributes to extend the population-genetical characterisation of biological function. To support this statement a mathematic...
