according to the reports of who, stability of rev.1 vaccine should take more than one year, while the expiring date for the vaccine produced in iran is 3 to 4 months, therefore any attempt to elongate the stability of this vaccine can solve many problems of the production including the request of veterinary organization of iran in this regard. the objective of this study was to increase the sta...

8 In his paper " Lagrange interpolation on Chebyshev points of two variables " (J. 9 220–238), Y. Xu proposed a set of Chebyshev like points for polynomial interpolation in the square 10 [−1, 1] 2 , and derived a compact form of the corresponding Lagrange interpolation formula. We inves-11 tigate computational aspects of the Xu polynomial interpolation formula like numerical stability and 12 ef...

In this paper we present a shape preserving method of interpolation for scattered data defined in the form of some constraints such as convexity, monotonicity and positivity. We define a k-convex interpolation spline function in a Sobolev space, by minimizing a semi-norm of order k+1, and we discretize it in the space of piecewise polynomial spline functions. The shape preserving condition that...

We study how to use bivariate splines for scattered data interpolation and fitting with preservation of non-negativity of the data values. We propose a minimal energy method to find a C1 smooth interpolation/fitting of non-negative data values from scattered locations based on bivariate splines. We establish the existence and uniqueness of the minimizer under mild assumptions on the data locati...

In this paper, we study the stability of a wide class of switched systems using stability preserving mappings. By considering an existing result and extending it to a general class of switched systems, we show that stability preserving mappings constitute an important and practical tool in stability analysis and design of switched systems.

In this paper, reduced-order models (ROMs) are constructed for the Ablowitz-Ladik equation (ALE), an integrable semi-discretization of nonlinear Schrödinger (NLSE) with and without damping. Both ALEs non-canonical conservative dissipative Hamiltonian systems Poisson matrix depending quadratically on state variables, quadratic Hamiltonian. The full-order solutions obtained energy preserving midp...
