In this paper, the homotopy analysis method (HAM) is successfully applied to the fractional Sharma-Tasso-Olver equation to obtain its approximate analytical solutions. Comparison of the obtained results with those of variational iteration method (VIM), Adomian’s decomposition method (ADM) and homotopy perturbation method (HPM) has led us to conclude that the method gives...
In this paper we prove that the entropy of a fuzzy measure preserving transformation with respect to a sub-σ-algebra having finite atoms is affine and then we extend the method of computing the entropy of a finite sub-σ-algebra to a sub-σ-algebra having countable atoms, and we investigate the ergodic properties of fuzzy probability dynamical systems. At the end by using this...

The paper investigates a numerical method for the second kind Fredholm integral equation with weakly singular kernel k(x, y), in particular, when k(x, y) = ln |x−y|, and k(x, y) = |x − y| −α, −1 ≤ x, y ≤ 1, 0 < α < 1. The solutions of such equations may exhibit a singular behaviour in the neighbourhood of the endpoints x = ±1. We introduce a new smoothing transformation based on...

We then fully embed the just mentioned categories of preclass-valued lax presheaves on X , in certain categories of topological functors on X . Combining the full embeddings obtained, we...
Injectivity of dynamical systems and essential extension of any dynamical system are the most important notions in this paper. We prove the existence of injective extension for any dynamical system. Also we see that every dynamical system without any proper essential extension is injective.
In this paper the concept of outer product for R 4 is considered. By using this outer product a new product on R 5 is introduced. R 5 with this product and usual addition and scalar multiplication is an associative algebra. Via this algebra a new representation for quaternions as a Lie group is presented. Moreover a representation for SU(2) is deduced.
In this paper, partition and entropy of partitions in a D-poset are introduced and their properties are investigated. Also we introduce the conditional entropy and then we study some their results. At the end we define the entropy of a dynamical system, we prove some results on that, and we show its invariance.
Digital image steganography techniques deal with three subjects lossy/lossless compressed images, uncompressed images. Steganography techniques embed secret data pixel directly into uncompressed and lossless compressed cover images. The most popular data hiding method is, changing pixels’ left most digits or last two, known as Least Significant Bit (LSB). Lossless image formats...
The present paper examines the effect of thermal radiation on steady MHD mixed convection over a vertical plate with a convective boundary condition embedded in a porous medium. The effect of chemical reaction is also taken into account and hence a first-order chemical reaction is considered. Firstly, the governing equations of fluid have been written into a normalized form and...

In this article, a new method known as the Chebyshev wavelet collocation method is presented for the solution of second-order linear ordinary differential equations (ODEs). The method is based on the approximation of the truncated Chebyshev wavelet series. By using the Chebyshev collocation points, an algebraic equation system has been obtained and solved. Hence the implicit...
The general function of a matrix converter is to conver AC supply to variable-voltage variable-frequency outputs. A new matrix is presented to reduce harmonic components in the output voltage. The transfer ratio has improved in the proposed converter. The structure of the proposed converter is identical to the cascaded H-bridge multilevel converter, but here the switches are bi...
In this paper, the Homotopy Analysis Method (HAM) is applied to the damped Burgers and Boussinesq-Burgers equations to obtain their approximate analytical solutions. The HAM solution includes an auxiliary parameter h¯ which provides a convenient way to adjust and control the convergence region of the solution series. An appropriate choice of the auxiliary parameter in the model...

A new version of Jacobs Theorem concerning the entropy of a dynamical system is...
Globally, hyperbolic spacetimes are the simplest kind of spacetimes which are studied in General Relativity. It is shown by Martin and Panangaden that it is possible to reconstruct globally hyperbolic spacetimes in a purely order theoretic manner using the causal relation J +. Indeed these spacetimes belong to a category that is equivalent to a special category of domains known...

We introduce the notion of commutators in BCK-algebras and also discuss their properties. It has been found that the sub-algebras, isomorphic image and inverse image of a solvable BCKalgebras are still solvable BCK-algebras.
