A Subclass of Analytic-Functions Defined By Using Certain Operators of Fractional Calculus
(Pergamon-Elsevier Science Ltd, 1995)Making use of certain operators of fractional calculus, we introduce a new class F-delta(n,lambda,alpha) of functions which are analytic in the open unit disk mu and obtain a necessary and sufficient condition for a function ... -
A Textural View of The Distinction Between Uniformities and Quasi-Uniformities
(Elsevier Science Bv, 2006)In this paper the authors consider the interplay between di-uniformities on a texture and a complementation on that texture. It is shown that with each di-uniformity corresponds a second di-uniformity, called its complement. ... -
Almost-Perfect Modules
(Cambridge Univ Press, 2010)We call a module M almost perfect if every M-generated flat module is M-projective. Any perfect module is almost perfect. We characterize almost-perfect modules and investigate some of their properties. It is proved that ... -
An Alternative Perspective on Injectivity of Modules
(Academic Press Inc Elsevier Science, 2011)Given modules M and N, M is said to be N-subinjective if for every extension K of N and every homomorphism : N M there exists a homomorphism phi : K -> M such that phi vertical bar N = phi. For a module M, the subinjectivity ... -
An Analytic Shooting-Like Approach For The Solution of Nonlinear Boundary Value Problems
(Pergamon-Elsevier Science Ltd, 2011)In this paper a novel approach is presented for an analytic approximate solution of nonlinear differential equations with boundary conditions. By converting the nonlinear problem into an initial value form, a shooting-like ... -
An Asymptotic Investigation Into The Stabilization Effect Of Suction In The Rotating-Disk Boundary Layer Flow
(Pergamon-Elsevier Science Ltd, 2007)The suction effects in the three-dimensional boundary layer flow due to a rotating disk are analyzed from the linear stability point of view making use of the asymptotic structure of the suction mean velocity profiles of ... -
An Extension of the Incomplete Beta Function For Negative Integers
(Academic Press Inc Elsevier Science, 2008)The incomplete beta function B-x(a, b) is defined for a, b > 0 and 0 < x < 1. Its definition can be extended, by regularization, to negative non-integer values of a and b. In this paper we define the incomplete beta function ... -
An Optimal Variational Iteration Method
(Pergamon-Elsevier Science Ltd, 2011)The variational iteration method is studied in the present work. The classical variational iteration method is improved and extended by introducing a new concept of a convergence accelerating parameter. A rigorous approach ... -
An Unconventional Finite Difference Scheme For Modified Korteweg-De Vries Equation
(Hindawi Ltd, 2017)A numerical solution of the modified Korteweg-de Vries (MKdV) equation is presented by using a nonstandard finite difference (NSFD) scheme with theta method which includes the implicit Euler and a Crank-Nicolson type ... -
Analytic Approximate Solutions of Parameterized Unperturbed And Singularly Perturbed Boundary Value Problems
(Elsevier Science Inc, 2011)A novel approach is presented in this paper for approximate solution of parameterized unperturbed and singularly perturbed two-point boundary value problems. The problem is first separated into a simultaneous system regarding ... -
Antimicrobial Activities of Some Bacillus Spp. Strains Isolated From The Soil
(Elsevier Gmbh, Urban & Fischer Verlag, 2006)In this study a total of 29 Bacillus species isolated from the soil was analyzed using the agar diffusion method in terms of their general, inhibition effects to some test bacteria. It has been found that isolates are ... -
Asymptotic Behaviour of a Class of Nonlinear Functional Differential Equations of Third Order
(Pergamon-Elsevier Science Ltd, 2001)This paper deals with nonoscillatory behaviour of solutions of third-order nonlinear functional differential equations of the form y''' + p(t)y' + q(t)F(y(g(t))) = 0. It has been shown that under certain conditions on ... -
Asymptotic Calculation of Inviscidly Absolutely Unstable Modes of the Compressible Boundary Layer on a Rotating Disk
(Pergamon-Elsevier Science Ltd, 2006)In this work a long-wavelength asymptotic approach is used to analyze the region of absolute instability in the compressible rotating disk boundary layer flow. Theoretically determined values of branch points for the ... -
Blow-Up of Solutions to Quasilinear Parabolic Equations
(Pergamon-Elsevier Science Ltd, 1999)Sufficient conditions for global nonexistence (blow up) of solutions of the initial-boundary value problem for a class of second-order quasilinear parabolic equations: [GRAPHICS] are established. (C) 1999 Elsevier Science ... -
Categories of Rough Sets and Textures
(Elsevier Science Bv, 2013)It is known that the theories of rough sets and fuzzy sets have successful applications in computing. Textures, as a theoretical model, provide a new perspective for both rough sets and fuzzy sets. Indeed, recent papers ... -
Completeness Types For Uniformity Theory On Textures
(Univ Nis, Fac Sci Math, 2015)In this paper the author considers the various types of completeness for di-uniform texture spaces and especially for complemented ones. Following that, the relationships between completeness of uniform spaces and these ... -
Complex And Symplectic Structures On Panelled Web 4-Manifolds
(Elsevier Science Bv, 2012)We analyze the symplectic and complex structures on the panelled web 4-manifolds of S. Akbulut and M. Kalafat [1]. In particular, we give infinite families of examples of almost complex but not symplectic and not complex ... -
