A fuzzy observer based scheme for synchronizing two hyperchaoticoscillators via a scalar transmitted signal for cryptographic application isproposed. The Takagi-Sugeno fuzzy model exactly represents chaotic systems.Based on the general fuzzy model, the fuzzy observer of a chaotic system isdesigned on the basis of the n-shift multiple state based key encryption algorithm.The scalar transmitted s...

An oscillating, homogeneous and isotropic Universe which arises from Scalar-Tensor gravity is discussed in the linearized approach, showing that some observative evidences like the Hubble Law and the Cosmological Redshift are in agreement with the model. In this context Dark Energy appears like a pure curvature effect arising by the scalar field. PACS numbers: 04.80.Nn, 04.30.Nk, 04.50.+h

The aim of this paper is to present a method computer formulation and solution equations kinematics spatial mechanical systems. the vector closed loop generally known way how built constraint equations. This recommended for planar kinematics. shows take advantage cross product, magnitude scalar product two vectors getting mechanism.

In this paper, we present a numerical technique for performing Lie advection of arbitrary differential forms. Leveraging advances in high-resolution finite volume methods for scalar hyperbolic conservation laws, we first discretize the interior product (also called contraction) through integrals over Eulerian approximations of extrusions. This, along with Cartan’s homotopy formula and a discret...

Let Mn be the set of n × n complex matrices, and for every A ∈ Mn, let Sp(A) denote the spectrum of A. For various types of products A1 ∗ · · · ∗ Ak on Mn, it is shown that a mapping φ : Mn → Mn satisfying Sp(A1 ∗ · · · ∗ Ak) = Sp(φ(A1) ∗ · · · ∗ φ(Ak)) for all A1, . . . , Ak ∈ Mn has the form X → ξS−1XS or A → ξS−1XtS for some invertible S ∈ Mn and scalar ξ. The result covers the special cases...

Starting from a complete operator product expansion up to mass dimension-6 twist4 and up to first order in the coupling constants we investigate the splitting and mixing of ρ and ω mesons in isospin symmetric nuclear matter. Special attention is devoted to the impact of the scalar 4-quark condensates on both effects. In nuclear matter the Landau damping governs the ρ−ω mass splitting while the ...

This paper discusses Sobolev orthogonal polynomials for a class of scalar products that contains the sequentially dominated products introduced by G. L. Lagomasino and H. Pijeira. We prove asymptotics for Markov type functions associated to the Sobolev scalar product and an extension of Widom’s Theorem on the location of the zeroes of the orthogonal polynomials. In the case of measures supporte...
