TL;DR: The main idea behind this work is the use of the well-known Adomian decomposition method, and in this technique, the solution is found in the form of a rapid convergent series.
Abstract: In this paper, a method for solving multipoint boundary value problems is presented. The main idea behind this work is the use of the well-known Adomian decomposition method. In this technique, the solution is found in the form of a rapid convergent series. Using this method, it is possible to obtain the solution of the general form of multipoint boundary value problems. The Adomian decomposition method is not affected by computation round off errors and one is not faced with the necessity of large computer memory and time. To show the efficiency of the developed method, numerical results are presented.

TL;DR: A new robust two-stage multi-period stochastic model for the blood supply network design with the consideration of a possible natural disaster and the possibility of transfusion of one blood type as well as its derivatives to other types based on the medical requirements is considered in the optimization model.
Abstract: In a natural disaster such as an earthquake, very often due to the extensive number of severe injuries, demands for blood units sharply increase in emergency hospitals. Regarding such a problem, we propose a new robust two-stage multi-period stochastic model for the blood supply network design with the consideration of a possible natural disaster. The demand for blood units from different types and their derivatives including plasma and platelets are uncertain variables. As a novel contribution, the possibility of transfusion of one blood type as well as its derivatives to other types based on the medical requirements is considered in the optimization model. The pertinent network consists of three layers including the donated areas, the collection blood centers, and the transfusion blood center, which is usually a governmental organization. The model is also constructed for considering a likely earthquake in Tehran (the capital of Islamic Republic of Iran) using a professional report prepared in the year 1999 and also updated in a next research work. The scenarios for the demands of blood units and their derivatives are generated based on these reports. The mathematical model is implemented and assessed in a proper way using the simulation method.

TL;DR: In this paper, a compact finite difference approximation of fourth order for discretizing spatial derivatives of linear hyperbolic equation and collocation method for the time component is introduced, which is unconditionally stable and solves the two-dimensional linear hyper bolic equation with high accuracy.
Abstract: In this article, we introduce a high-order accurate method for solving the two dimensional linear hyperbolic equation We apply a compact finite difference approximation of fourth order for discretizing spatial derivatives of linear hyperbolic equation and collocation method for the time component The resulted method is unconditionally stable and solves the two-dimensional linear hyperbolic equation with high accuracy In this technique, the solution is approximated by a polynomial at each grid point that its coefficients are determined by solving a linear system of equations Numerical results show that the compact finite difference approximation of fourth order and collocation method give a very efficient approach for solving the two dimensional linear hyperbolic equation © 2008 Wiley Periodicals, Inc Numer Methods Partial Differential Eq, 2009
