Spline Method with Three Collocation Parameters for Solving Ninth-Order General Differential Equations Subject to Boundary Conditions

In this paper, we use polynomial splines of eleventh degree with three collocation points to develop a method for computing approximations to the solution and its derivatives up to ninth order for general linear and nonlinear ninth-order boundary-value problems (BVPs). The study shows that the spline method with three collocation points when is applied to these problems is existent and unique. We prove that the proposed method if applied to ninth-order BVPs is stable and consistent of order eleven, and it possesses convergence rate greater than six. Finally, some numerical experiments are presented for illustrating the theoretical results and by comparing the results of our method with the other methods, we reveal that the proposed method is better than others.

Techno-media AND DEVELOPMENT IN SYRIA

This study is about the concept of techno-media in Syria, where the world developing techno-media has been identified. As well as there has been a survy on the spreading of technological applications between memberships and this has been done through presenting evidence about the usage of technological applications in Syria comparing with other countries. Also, the study has identified the most important problems of techno-media. Besides the study has also found out some important elements that identified the techno-media and helps in activating it, aiming to find out other reasons there has been a survy on the connecting relations between problems that lay behind technomedia and how much it is used. After that we have produced some important illustrations and instructions that will have its impact on developing and supporting the process of having technological media and how will this serve the community and participate in improving it.

Numerical Simulation Stochastic of Differential Equations by Using Spline Function Approximations

In this paper, spline approximations with five collocation points are used for the numerical simulation of stochastic of differential equations(SDE). First, we have modeled continuous-valued discrete wiener process, and then numerical asymptotic stochastic stability of spline method is studied when applied to SDEs. The study shows that the method when applied to linear and nonlinear SDEs are stable and convergent. Moreover, the scheme is tested on two linear and nonlinear problems to illustrate the applicability and efficiency of the purposed method. Comparisons of our results with Euler–Maruyama method, Milstein’s method and Runge-Kutta method, it reveals that the our scheme is better than others.

Numerical Method for Finding Single and Multiple Integrals

In this paper, an iterative numerical method for obtaining approximate values of definite single, double and triple integrals will be illustrated. This method depends on approximating the single integral function by spline polynomial of fifth degree, while Gauss Legendre points as well as spline polynomials are used for finding multiple integrals. The study shows that when the method are applied to single integrals is convergent of order sixth, as well as when applied to triple integrals is convergent of order sixth for three Gauss Legendre points or greater. Errors estimates of the proposed method alongside numerical examples are given to test the convergence and accuracy of the method.

Study of the Long Term Stability of Butrylcholinesterase and its Dependence on Sex and Age

Specimens of serum from ١٦٨ healthy subjects (٨٠ men and ٨٨ women, ages ١٨ to ٧٨ years)were divided into three groups: fresh, storage at ٤°C, and freezing at-٢٠°C . Periodic essays for the activity of Butrylcholinesterase (BChE,EC. ٣٫١٫١٫٨) were made on each frozen and unfrozen specimen. Serum frozen at-٢٠°C and left at ٤°C gave results similar to those from fresh specimens. Comparison of samples from men and women revealed significantly higher activity in men than in women (P<٠٫٠٠١). Activity was greatest in men aged ١٨-٥٠ years and then declined to slightly lower values. In women the activity was less in those under ٥٠ years old than in those above ٥٠.
