Assume we have a set of k colors and to each vertex of a graph G we assign an arbitry of these colors. If we require that each vertex to set is assigned has in its closed neighborhood all k colors, then this is called the generalized k-rainbow dominating function of a graph G. The corresponding γgkr, which is the minimum sum of numbers of assigned colores over all vertices of G, is called the gk-rainbow domination number of G. In this paper we present a linear algorithms for determining a minimum generalized 2-rainbow dominating set of a tree and on GP(n,2).

One of the most important methods for solving linear and nonlinear problems is the homotopic analysis method, which was proposed by Liao in 1992. The main purpose of this paper is to present a modification of homotopy analysis method (HAM), which is called successive homotopy analysis method (SHAM). Several numerical examples are presented to present a comparison between the results obtained by homotopy analysis method and its successive type. The results show that the calculation volume in the successive homotopy analysis method is less that the homotopy analysis method. Also, unlike the homotopy analysis method, the numerical solutions obtained by the successive homotopy analysis method are satisfactory over a relatively wide range. So, by using the successive homotopy analysis method, various types of linear and nonlinear mathematical equations and also some nonlinear equations which are obtained in other scientific branches, for instance physics, mechanics and etc, can be solved numerically.

Ghanbari and Mojdeh \cite{gm} initiated the concept of restrained2-rainbow domination in graphs. In this paper is given upperbounds for 2-restrained domination number of a particular case ofgeneralized Petersen graphs.

Alienation is a phenomenon dating back to human history that has a broad meaning. The concept of this phenomenon starts from romantic homelessness, which is the result of nostalgia and return to childhood, and extends to psychological alienation, which is the result of escaping from the pursuit of political and social conditions. This phenomenon has increased in some periods for various reasons. In the contemporary era, the Algerian people have been affected by this phenomenon due to the presence of colonialism and the resulting economic and social crises. The Algerian novelist Abdelhamid ben Hadouga, who felt the consequences of the presence of colonialism in this period, reflected alienation in his works. Relying on a descriptive-analytical method, this research seeks to investigate the phenomenon of intrinsic and cultural alienation based on Melvin Seaman's theory of alienation in the novel "The New Day Food". Findings of the research indicate that the author has been able to present a manifestation of alienation that is the result of the presence of colonialism and the result of some old traditions in the form of story characters and while criticizing this phenomenon has tried Suggest your own identity and culture to deal with it.

Honeycomb networks are built recursively using hexagonal tessellations. Wireless networks such as satellite networks, radio networks, sensor networks, cellular networks, ad hoc networks and other mobile network where honeycomb networks is used extensively. In this paper we study upper bound for restrained double Roman domination number for honeycomb networks.

The post-colonial feminism is a new feministic approach that deals with the cultural, economic and political impacts of colonialism on the women of non-western races in developing countries especially those that were once colonized.Indeed, the approach seeks to question the proclaimed comprehensiveness of the western theory of feminism by addressing the problems and experiences of women in marginal communities The novel Ghadan Youm ol-Jadid (Tomorrow is a New Day) by Abd ol-Hamid Bin Hadouqheh depicts the women’s status during the colonial time by making realistic references to the discriminations against them. The present study is an attempt to examine this issue in the novel through a descriptive-analytic method. The question to answer in this research is ‘How does the novel classify the women in terms of their function?’ and ‘How does the author react to their inferiority?’ As the results show,the women discussed in the novel are either Europeans or natives. The former are a part of colonial policies and look down on the other women. The latter, however, include married women who are passive and quite easy to dominate, as compared to the unmarried. Such women are found responsible for their own inferiority because they help it to take roots. In this regard, Bin Hadouqheh charges the patriarchal society of cooperating with colonizers to oppress women and then asks for the redemption of their rights. He also calls for a change of their situation from the margin to the center on the purpose of granting them a decent identity.

The construction of a control is usually based on completeinformation on the coordinates of an object. In the absence ofthis information, the control can be constructed by solving twoconsecutive sub problems, namely, detecting a desired object andcapturing the target object with complete information on itscoordinates. In this paper we suppose that start-point for motionsis variable and using the diagrams constructed in the plane ofgeometric objects of the operation zone of the manipulator, theproblem of selecting a control under which a guaranteed searchwith a subsequent capture of a target object is carried out in aminimum time is solved.

We the revolution are coming or bringing in different theories of structure lism and agent oriented is of different answers. The present study is seeking to analys the success of Islamic republic of iran revolution the encounter of structure agent so answering the question of how the agent in case of iran benifited from the confradication of that time stracture and successed but in Egypt this was a temporary success and failed at the end? Comparing the international structure of time and familiarity withe the how of using failure of egyption agent failure is great importance white is the main focus of this study analysis.In this research, we are trying to explain how the agents of the Islamic Revolution of Iran, such as leadership, social forces and the army, were able to stabilize their political system in front of the international structure, but this success was not achieved in Egypt.

The unit disk graph is used to model a wireless sensor network when all sensors have the same communication radius. Hence, the following two optimization problems have been investigated by the researchers: maximal independent set in the network and minimal network dominating set. Since these problems are Np-hard, several algorithms have been presented for their approximation. In this paper, we have presented a honeycomb graph and algorithmic matrix methods for approximating the maximal independent set in the network. Finally, we have confirmed the validity of the algorithm and its complexity and studied it with a numerical example.

Literature of a nation consists of components that serve as the best and most visible means of understanding the attitudes and the worldview of that nation. When it comes to recounting the intellectual foundations of a nation in the field of literature, post-colonial literature has a great contribution. This is because it expresses the attitudes and positions of that nation against foreign colonialism. The long-standing presence of French colonialism in Algeria has led to the emergence and prosperity of post-colonial literature in that country. The novel "Ghadan youmon jadid" by "Abdol Hamid ibn-e Hadouqa" narrates the effects of colonial racism on the people of Algeria. Using a descriptive-analytical method, the present research seeks to analyze the most important fields of colonial racism in the novel and interpret them with examples. It also addresses the reasons for the emergence of colonial racism in the characters of the story and the way the author resolves this problem. The post-colonial analysis of the novel suggests that colonial racism has been practiced in the biological, religious, judicial, and internal aspects of the society. Vocational monopoly is another manifestation of racism. The author's strategy to get out of this crisis is to rely on indigenous culture and history, to gain knowledge about Europeans, and to reinforce the spirit of unity, resistance and oppression in the people.

In this manuscript, we introduce a new class of fuzzy problems, namely ``fuzzy inclusion linear systems" and propose a fuzzy solution set for it. Then, we present a theoretical discussion about the relationship between the fuzzy solution set of a fuzzy inclusion linear system and the algebraic solution of a fuzzy linear system. New necessary and sufficient conditions are derived for obtaining the unique algebraic solution for a fuzzy linear system. Also, all new concepts are illustrated by numerical examples.

In this paper, a fuzzy numerical procedure for solving fuzzy linear Volterra integro-differential equations of the second kind under strong generalized differentiability is designed. Unlike the existing numerical methods, we do not replace the original fuzzy equation by a $2\times 2$ system of crisp equations, that is the main difference between our method and other numerical methods. Error analysis and numerical examples are given to show the convergency and efficiency of the proposed method, respectively.

In this paper, we apply the homotopy analysis method (HAM) for solving fuzzy linear systems and present the necessary and sufficient conditions for the convergence of series solution obtained via the HAM. Also, we present a new criterion for choosing a proper value of convergence-control parameter $hbar$ when the HAM is applied to linear system of equations. Comparisons are made between the results of the HAM and several well-known numerical algorithms such as Jacobi method (JM), Gauss-Seidel method (GSM), successive over relaxation method (SOR), Adomian decomposition method (ADM) and homotopy perturbation method (HPM).

Recently, Abbasbandy and Asady have been proposed a modification of the distance based approach, namely ``sign distance method''. However, in this paper, it is shown that this method has some drawbacks, i.e., the result is not consistent with human intuition for special cases and this method cannot always logically infer ranking order of the images of the fuzzy numbers. In this paper, we present a revised method which can avoid these problems for ranking fuzzy numbers. Also, we present several properties for revised sign distance method while the original method does not have some of them.

In this paper, we show that the computed distance between two fuzzy numbers using the fuzzy distance measure proposed by Chakraborty et al. [Mathematical and Computer Modelling 43 (2006) 254 261] is not always a fuzzy number. Then, we improve it and prove that the result of the revised distance is always a nonnegative fuzzy number.

Integral equations have many applications in the theory of elasticity, engineering, mathematical physics, potential theory, electrostatic and radiative heat transfer problems. In this paper, we present a method for solving fuzzy linear Fredholm integral equations of the second kind, namely “homotopy analysis method” (HAM). It is found that the HAM provides us with a simple way to adjust and control the convergence region of solution series by introducing convergence-control parameter ~, which is the main advantage of this method.
