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.
The scientific abandonment of the most important places of education and science in the Happy Yemen, which Manfred them from the rest of the Islamic Alomassar such kind of places Education existence, has contributed to a variety of factors paved the way for the emergence and originated scientific migration in the (fifth century AH / atheist century AD), and was in the forefront divisions witnessed by the Zaidi sect to if divided into three teams are (Almpartyah and inventor and Husseiniya) Because of differences doctrinal debates Pima including a heated end the fighting of the conflict between the parties,

It was very useful to get use of the potentialities of this system of GIS in the field of archaeology and to harvest very accurate results in a relatively short time, compared to the old archaeological methods.
The family is considered one of the most important social institutions which has a
strong and clear effect on the child in forming his personality through the process
of social upbringing which works on transforming the child from a merely
biological being into an individual who has customs and traditions and the behavior
of the group to which he belongs, and till now there is no social organization or
institution that can do this process not even in partial way like the family
.Therefore depriving the child of his parents leads to depriving him of the normal
chances of growth which relate to his age stage and thus this shortcoming is hard to
treat and based on the preceding the current research aimed at the follo
Despite the G protein-coupled receptors (GPCRs) being the largest family of signalling proteins at the surface of cells, their potential to be targeted in cancer therapy is still under-utilised. This review highlights the contribution of these receptors to the process of oncogenesis and points to some likely challenges that might be encountered in targeting them. GPCR-signalling pathways are often complex and can be tissue-specific. Cancer cells hijack these communication networks to their proliferative advantage. The role of selected GPCRs in the different hallmarks of cancer is examined to highlight the complexity of targeting these receptors for therapeutic benefit. Our
