In this paper we examine the effects of spatial fading correlation on bit-error probability (BEP) and channel capacity of orthogonal space–time block codes (STBCs) over multiple-input multiple-output (MIMO) Weibull fading channel. We derive the characteristic function (cf) of the signal-to-noise ratio (SNR) which is linear combination of Laplace transforms weighted by the eigenvalues of the cha...

BACKGROUND AND PURPOSE Diagnosis of AS and periaqueductal abnormalities by routine MR imaging sequences is challenging for neuroradiologists. The aim of our study was to evaluate the utility of the 3D-SPACE sequence with VFAM in patients with suspected AS. MATERIALS AND METHODS PC-MRI and 3D-SPACE images were obtained in 21 patients who had hydrocephalus on routine MR imaging scans and had cl...

‎By considering a degenerate $p(x)-$Laplacian equation‎, ‎a generalized compact embedding in weighted variable‎ ‎exponent Sobolev space is presented‎. ‎Multiplicity of positive solutions are discussed by applying fibering map approach for the‎ ‎corresponding Nehari manifold‎. 

In this paper Li–Yorke chaotic sets generated by shift and weighted shift maps are studied. The characterization of Li–Yorke chaotic sets by p-scrambled sets, maximal scrambled sets and orbit invariants are proved for the general shift maps. For weighted shift maps on infinite-dimensional spaces, the necessary and sufficient conditions for Li–Yorke chaotic are proved both in the abstract sequen...

In the present paper, we introduce the sequence space [{l_p}(E,Delta) = left{ x = (x_n)_{n = 1}^infty : sum_{n = 1}^infty left|  sum_{j in {E_n}} x_j - sum_{j in E_{n + 1}} x_jright| ^p < infty right},] where $E=(E_n)$ is a partition of finite subsets of the positive integers and $pge 1$. We investigate its topological properties and inclusion relations. Moreover, we consider the problem of fin...

The purpose of this paper is to discuss the degree best monotone multi- approximation unbounded functions weighted space in terms modules smoothness by using some algebraic linear operators. In addition, introduced ,proofs properties modulus smoothness.

Let $Omega_X$ be a bounded, circular and strictly convex domain of a Banach space $X$ and $mathcal{H}(Omega_X)$ denote the space of all holomorphic functions defined on $Omega_X$. The growth space $mathcal{A}^omega(Omega_X)$ is the space of all $finmathcal{H}(Omega_X)$ for which $$|f(x)|leqslant C omega(r_{Omega_X}(x)),quad xin Omega_X,$$ for some constant $C>0$, whenever $r_{Omega_X}$ is the M...

We study the asymptotic shape of random unlabelled graphs subject to certain subcriticality conditions. The are sampled with probability proportional a product Boltzmann weights assigned their $2$-connected components. As number vertices tends infinity, we show that they admit Brownian tree as Gromov–Hausdorff–Prokhorov scaling limit, and converge in strengthened Benjamini–Schramm sense toward ...
