This paper presents a set of new receiver structures for the detection of weak signals in nonGaussian noise. The receiver structures result from an extension of the likelihood ratio based on the information generating function of a density. These detectors are termed self-critical in that the assumed noise probability density function serves as an adaptive factor in the information processing a...

We present a brief review of brane-world models — models in which our observable Universe with its standard matter fields is assumed as localized on a domain wall (three-brane) in a higher dimensional surrounding (bulk) spacetime. Models of this type arise naturally in M-theory and have been intensively studied during the last years. We pay particular attention to the covariant projection appro...

Electromagnetic wave scattering by many parallel infinite cylinders is studied asymptotically as a → 0. Here a is the radius of the cylinders. It is assumed that the points x̂m are distributed so that N (∆) = 1 a R ∆ N(x)dx[1+o(1)], whereN (∆) is the number of points x̂m = (xm1, xm2) in an arbitrary open subset of the plane xoy, the axes of the cylinders are passing through points x̂m, these axes ...

Adaptive networks include a set of nodes with adaptation and learning abilities for modeling various types of self-organized and complex activities encountered in the real world. This paper presents the effect of heterogeneously distributed incremental LMS algorithm with ideal links on the quality of unknown parameter estimation. In heterogeneous adaptive networks, a fraction of the nodes, defi...
