Estimation the unknown parameters of a two-dimensional sinusoidal signal model is an important and a difficult problem , The importance of this model in modeling Symmetric gray- scale texture image . In this paper, we propose employment Deferential Evaluation algorithm and the use of Sequential approach to estimate the unknown frequencies and amplitudes of the 2-D sinusoidal components when the signal is affected by noise. Numerical simulation are performed for different sample size, and various level of standard deviation to observe the performance of this method in estimate the parameters of 2-D sinusoidal signal model , This model was used for modeling the Symmetric gray scale texture image and estimating by using proposed method, we have conclude that the 2-D Sinusoidal signal model can be effectively used to model symmetric gray- scale texture image and The efficiency of the proposed method to estimate model parameters.
Fraud Includes acts involving the exercise of deception by multiple parties inside and outside companies in order to obtain economic benefits against the harm to those companies, as they are to commit fraud upon the availability of three factors which represented by the existence of opportunities, motivation, and rationalization. Fraud detecting require necessity of indications the possibility of its existence. Here, Benford’s law can play an important role in direct the light towards the possibility of the existence of financial fraud in the accounting records of the company, which provides the required effort and time for detect fraud and prevent it.

This research shows Ibn Battuta's approach in his book Ibn Battuta's Journey that is called "Tuhfet Al-Anzar fi Ghera'ib Al-Amsar wa Eaja'ib-Al-Asfar", which explore the urban aspects of shops, markets, palaces, houses, mosques, monasteries and other antiquities within its pages, whether in terms of the site or in terms of studying it and the plans that explained the basis for the art and architecture of these cities, the intellectual dimensions in their civilizational history are clarified
Books of plans are a type of writing in Islamic history , its a type of work whose authors have strived to serve as a comprehensive historical encyclopedia, and they focused most of their attention on highlighting the various aspects of the history of Egypt
There was an ancient Myth came from cuneiform texts which had written by ancient Iraqi , its hero is the goddess Nerottaa .it was appeared in two languages Sumerian and Akkadian .

Literary heritage and its employment in poetry has received the attention of poets, and they have employed it in their literary texts, as this employment is one of the oldest phenomena in Arabic literature, that the inspiration of this heritage in texts through the overlap of their texts with previous texts, and no poet neglected the importance of this employment. The ancient critics determined that the poet’s special culture is represented in the necessity of taking from the ancients, and this taking is the reference from which the poet draws his material and idea, as well as to clarify the meaning and its significance
