Sabriraghadasm@yahoo.com<span>In this paper, the solution of the nonlinear equation is evaluated using Newton method, and then an extrapolation procedure with Aitken method is applied to improve and accelerated the Newton solution by reducing the number of iterations in order to find the roots of the nonlinear equation with minimum iterations. Several examples are solved using Newton Aitken technique. The comparison based on depending on the number of iterations. </span>2019-08-22T08:22:17+00:00Copyright (c) 2019 Raghad I.

Shihab100031@uotechnology.edu.iqSamaa Foud100031@uotechnology.edu.iqThe main purpose of this paper is the construction an explicit formula for modified Hermit function differentiation operational matrix and other new properties. Then an efficient approximate method is investigated for treating quadratic optimal control problem with the aid of the derived operation matrix. The technique essentially based on reducing the optimal problem indirectly to a system of linear algebraic equations in the expansion of unknown coefficients. The obtained numerical results are compared with the exact one.2019-08-23T03:38:55+00:00Copyright (c) 2019 Suha N.

A fuzzy logic calculates the modules according to both the degree of membership of the indices to the subsets (L), (M), (H) and a set of decision rules. Then the modules are aggregated into the indicator parameter output of solar cell is presented.</p>2019-08-28T01:14:11+00:00Copyright (c) 2019 Mohammed RASHEED, Mohammed Abdelhadi Sarhanhttps://insight.piscomed.com/index.php/MTA/article/view/212Solve and Implement the main Equations of Photovoltaic Cell Parameters Using Visual Studio Program2019-11-24T21:57:42+00:00Mohammed RASHEEDrasheed.mohammed40@yahoo.comMohammed Abdelhadi Sarhanrasheed.mohammed40@yahoo.com<p>In the present work the main equations of Photovoltaic cell parameters are desined and implemented using visual Studio program.

Suggest way to identify a start system of the proposed method is also included within this work. The obtained results are compared in terms of the iterations number and the application of the presented method based on studding several examples.</p>2019-08-28T01:32:01+00:00Copyright (c) 2019 Rasha Jalal Mitlif
