We present a new set of learning rules for the non-linear blind source separation problem based on the information maximization criterion. The mixing model is divided into a linear mixing part and a nonlinear transfer channel. The proposed model focuses on a paramet-ric sigmoidal nonlinearity and higher order polynomials. Our simulation results verify the convergence of the proposed algorithms.

This paper consists of two parts. First, a review of classical mixing principles lists the multitude of the various ways to characterize the effective permittivity of heterogeneous materials. Different connections between the various mixing formulas are underlined and the homogenization principles are classified into families of mixing rules. The second part emphasizes and analyzes the richness...

Application of cavity ring down (CRD) spectrometry for measuring the optical properties of pure and mixed laboratory-generated aerosols is presented. The extinction coefficient (α ext), extinction cross section (σ ext) and extinction efficiency (Q ext) were measured for polystyrene spheres (PSS), ammonium sulphate ((NH 4) 2 (SO 4)), sodium 5 chloride (NaCl), glutaric acid (GA), and Rhodamine-59...

This paper presents a discussion of complex shift dynamics of some elementary cellular automaton rules (rules 30, 41, and 110). Equations that show some degree of self-similarity are obtained. It is demonstrated that rules 30, 41, and 110 exhibit Bernoulli shifts and are topologically mixing on one of their own closed invariant subsystems. Furthermore, many complex Bernoulli shifts are explored...

Frustration is introduced in randomly connected totalistic cellular automata via mixing of rules leading to incompatible periods. As the respective concentration of rules is varied, these cellular automata go through 8 phases many of which with symmetries diierent from the two rules mixed in. The complex phase diagram so created is similar to those seen in frustrated systems in static equilibri...

In this work, we investigated the mixing between strange axial vector mesons K1(1270) and K1(1400) by using QCD Sum Rules approach. Since these states couple to same interpolating currents, defined them in terms of orbital angular momentum eigen K1A K1B. By tensor currents which are almost purely coupling K1B, then employing orthogonality physical states, obtained an analytical expression for K...
