The Korteweg-de Vries equation plays an important role in fluid physics and applied mathematics. This equation is a fundamental within study of shallow water waves. Since these equations arise in many applications and physical phenomena, it is officially showed that this equation has solitary waves as solutions, The Korteweg-de Vries equation is utilized to characterize a long waves travelling in channels. The goal of this paper is to construct the new effective frequent relation to resolve these problems where the semi analytic iterative technique presents new enforcement to solve Korteweg-de Vries equations. The distinctive feature of this method is, it can be utilized to get approximate solutions for travelling waves of non-linear partial differential equations with small amount of computations does not require to calculate restrictive assumptions or transformation like other conventional methods. In addition, several examples clarify the relevant features of this presented method, so the results of this study are debated to show that this method is a powerful tool and promising to illustrate the accuracy and efficiency for solving these problems. To evaluate the results in the iterative process we used the Matlab symbolic manipulator.
The estimation of the initial oil in place is a crucial topic in the period of exploration, appraisal, and development of the reservoir. In the current work, two conventional methods were used to determine the Initial Oil in Place. These two methods are a volumetric method and a reservoir simulation method. Moreover, each method requires a type of data whereet al the volumetric method depends on geological, core, well log and petrophysical properties data while the reservoir simulation method also needs capillary pressure versus water saturation, fluid production and static pressure data for all active wells at the Mishrif reservoir. The petrophysical properties for the studied reservoir is calculated using neural network technique
... Show MoreOscillation criteria are obtained for all solutions of the first-order linear delay differential equations with positive and negative coefficients where we established some sufficient conditions so that every solution of (1.1) oscillate. This paper generalized the results in [11]. Some examples are considered to illustrate our main results.
In this paper, we deal with games of fuzzy payoffs problem while there is uncertainty in data. We use the trapezoidal membership function to transform the data into fuzzy numbers and utilize the three different ranking function algorithms. Then we compare between these three ranking algorithms by using trapezoidal fuzzy numbers for the decision maker to get the best gains
La description, est une mode discursive et une forme d’écriture, consiste à rendre un objet en quelque sorte visible par l’exposition vive et animé des propriétés et des circonstances les plus intéressantes.
Elle occupe au XIXe ([1]) siècle une place centrale dans les œuvres littéraires. Cette technique a une place privilégiée chez les écrivains qui veulent représenter la vie telle quelle est.
Ce type de la représentation littéraire apparaît avec l’avènement du roman réaliste où se trouve de longs passages descriptifs dans les œuvres littéraires « Tout récit comporte…, quoique intimement mêlées et en proportions très vari

En este trabajo de investigación titulado, tratamos las bases científicas necesarias que debe seguir un crítico competente a la hora de elaborar un proceso critico extenso y preciso de las traducciones literarias de forma satisfactoria, teniendo en consideración mostrar los aspectos tanto lingüísticos como los extralingüísticos del texto original en comparación con el de meta. Actualmente el proceso crítico de las traducciones literarias se pone más importante a fin de aclarar posiciones débiles y de fuerza a las obras literarias y a sus traducciones.

The writings of famous French novelist Antoine de Saint- Exupery being describes his life and his career as a pilot. That's where aviation and modern means of transport at the beginning of the twentieth century. It is also through his writings that tainted documentary chronicled the history of occupied France by the Germans in World War II. Has contributed to the publication of documents and real events and attended by military missions. However, before he died, wrote us a novel immortal "The Little Prince ", which is quite different from previous writings in terms of dependence entirely on the imagination. And are almost close to science fiction to fact that the hero falls to the ground in a vague, of a small asteroid. We are tryi
... Show MoreIn this paper, we introduce and discuss an algorithm for the numerical solution of two- dimensional fractional partial differential equation with parameter. The algorithm for the numerical solution of this equation is based on implicit and an explicit difference method. Finally, numerical example is provided to illustrate that the numerical method for solving this equation is an effective solution method.
