A Study of Weighted Polynomial Approximations with Several Variables (II)
《Applied Mathematics》2017年第9期1239-1256,共18页Ryozi Sakai 
In this paper we investigate weighted polynomial approximations with several variables. Our study relates to the approximation for by weighted polynomial. Then we will give some results relating to the Lagrange interp...

γ and β Approximations via General Ordered Topological Spaces
《Applied Mathematics》2016年第14期1580-1588,共10页Mohamed Abo-Elhamayel 
In this paper, we introduce the concepts of g and b approximations via general ordered topological approximation spaces. Also, increasing (decreasing) g, b boundary, positive and negative regions are given in general ...

Convergence Properties of Piecewise Power Approximations
《Applied Mathematics》2016年第13期1440-1445,共16页Arcady Ponosov Anna Machina Valeria Tafintseva 
We address the problem of convergence of approximations obtained from two versions of the piecewise power-law representations arisen in Systems Biology. The most important cases of mean-square and uniform convergence ...

Method of Successive Approximations for a Fluid Structure Interaction Problem
《Applied Mathematics》2014年第15期2299-2304,共6页Aliou Gueye Sow Ibrahima Mbaye 
In this paper, we present a method for solving coupled problem. This method is mainly based on the successive approximations method. The external force acting on the structure is replaced by λ = p (x1, H + u (x1, λ)...

On the Efficacy of Fourier Series Approximations for Pricing European Options
《Applied Mathematics》2014年第17期2786-2807,共22页A. S. Hurn K. A. Lindsay A. J. McClelland 
This paper investigates several competing procedures for computing the prices of vanilla European options, such as puts, calls and binaries, in which the underlying model has a characteristic function that is known in...

Approximation by Splines of Hermite Type
《Applied Mathematics》2013年第11期5-10,共6页Yuri K. Dem’yanovich Irina G. Burova 
The approximation evaluations by polynomial splines are well-known. They are obtained by the similarity principle;in the case of non-polynomial splines the implementation of this principle is difficult. Another method...

The Conservation Laws and Stability of Fluid Waves of Permanent Form
《Applied Mathematics》2013年第3期486-490,共5页Troyan A. Bodnar 
The solution of Nekrasov’s integral equation is described. By means of this solution the wave kinetic, potential, and full mechanical energies are defined as functions of fluid depth and wavelength. The wave obeys th...

Convergence of Invariant Measures of Truncation Approximations to Markov Processes被引量：2
《Applied Mathematics》2012年第12期2205-2215,共11页Andrew G. Hart Richard L. Tweedie 
Let Q be the Q-matrix of an irreducible, positive recurrent Markov process on a countable state space. We show that, under a number of conditions, the stationary distributions of the n × n north-west corner augmentat...

On the Behavior of Combination High-Order Compact Approximations with Preconditioned Methods in the Diffusion-Convection Equation
《Applied Mathematics》2011年第12期1462-1468,共7页Ahmad Golbabai Mahboubeh Molavi-Arabshahi 
In this paper, a family of high-order compact finite difference methods in combination preconditioned methods are used for solution of the Diffusion-Convection equation. We developed numerical methods by replacing the...
