#### Observations On Quasi-Uniform Products

(Elsevier Science Bv, 2007)

We prove that any product of quotient maps in the category of quasi-uniform spaces and quasi-uniformly continuous maps is a quotient map. We also show that a quasi-uniformly continuous map from a product of quasi-uniform ...

#### Green'S Function, Temperature In A Convectively Cooled Sphere With Arbitrarily Located Spherical Heat Sources

(Elsevier Science Inc, 2009)

Steady state heat conduction in a convectively cooled sphere having arbitrarily located spherical heat sources inside is treated with the method of Green's function accompanied by a coordinate transform. Green's function ...

#### Forecasting Nonlinear Time Series With A Hybrid Methodology

(Pergamon-Elsevier Science Ltd, 2009)

In recent years, artificial neural networks (ANNs) have been used for forecasting in time series in the literature. Although it is possible to model both linear and nonlinear structures in time series by using ANNs, they ...

#### Defining The K(Th) Powers Of The Dirac-Delta Distribution For Negative Integers

(Pergamon-Elsevier Science Ltd, 2001)

In [1], Koh and Kuan defined the powers of the Dirac-delta distribution for positive integers. Here we extend their definition for negative integers. Also, we give meaning to the distribution delta (-kappa)(+). (C) 2001 ...

#### Interval Criteria for Oscillation of Second-Order Functional Differential Equations

(Pergamon-Elsevier Science Ltd, 2005)

By using averaging functions, new interval oscillation criteria are established for the second-order functional differential equation, (r (t) vertical bar x' (t)vertical bar(alpha-1) x' (t))' + F (t, x (t), x (tau (t)), ...

#### Lebesgue and Co-Lebesgue Di-Uniform Texture Spaces

(Elsevier Science Bv, 2009)

The author introduces the notions of Lebesgue di-uniformity and co Lebesgue di-uniformity and investigates the relationship between a Lebesgue quasi uniformity on X and the corresponding Lebesgue di-uniformity on the ...

#### Long-Time Behaviour of Wave Equations with Nonlinear Interior Damping

(Amer Inst Mathematical Sciences-Aims, 2008)

We prove the existence of attractors for higher dimensional wave equations with nonlinear interior damping which grows faster than polynomials at infinity.

#### Long-Time Behaviour of Doubly Nonlinear Parabolic Equations

(Amer Inst Mathematical Sciences-Aims, 2009)

We consider a doubly nonlinear parabolic equation in R-n. Under suitable hypotheses we prove that a semigroup generated by this equation possesses a global attractor.

#### Modified Estimators For The Change Point In Hazard Function

(Elsevier Science Bv, 2009)

We propose the consistent estimators for the change point in hazard function by improving the estimators in [A.P. Basu, J.K. Ghosh, S.N. Joshi, On estimating change point in a failure rate, in: S.S. Gupta,J.O. Berger (Eds.), ...

#### Improvement In Estimating The Population Mean In Simple Random Sampling

(Pergamon-Elsevier Science Ltd, 2006)

This paper proposes some estimators for the population mean using the ratio estimators presented in [C. Kadilar, H. Cingi, Ratio estimators in simple random sampling, Applied Mathematics and Computation 151 (2004) 893-902] ...

#### On The Noncommutative Neutrix Product Of Distributions

(Hindawi Publishing Corporation, 2007)

Let f and g be distributions and let g(n) = (g * delta(n))(x), where delta(n)(x) is a certain sequence converging to the Dirac-delta function delta( x). The noncommutative neutrix product f circle g of f and g is defined ...

#### On Powers Of The Heaviside Function For Negative Integers

(Academic Press Inc Elsevier Science, 2007)

The distributions (x(+)(r))(-s) and (x(+)(r))_(-s) were defined as the neutrix limit of the sequences ((x(+)(r))(-s))n and ((x(+)(r))_(-s))n respectively for r, s = 1, 2,..., see [J.D. Nicholos, B. Fisher, The distribution ...

#### Remarks on Separation of Convex Sets, Fixed-Point Theorem, and Applications in Theory of Linear Operators

(Springer International Publishing Ag, 2007)

Some properties of the linear continuous operator and separation of convex subsets are investigated in this paper and a dual space for a subspace of a reflexive Banach space with a strictly convex norm is constructed. Here ...

#### 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 ...

#### 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 ...
