السلطة التقديرية للادارة في مجال الضبط الاداري في الظروف العادية )دراسة مقا رنة ( في القانون الوضعي والشريعة الاسلامية

ان خضوع الادارة الى القانون يعني احترام الادارة القانونية المستمدة من مصادرها مختلفة وهذا يكفل على احسن وجه العدالة والمساواة بالنسبة الى المحكومين ويضمن ان تكون الادارة ملتزمة بلا تتجاوز حدود القواعد التي تنظم نشاطاتها وتحدد اختصاصاتها وتبين وسائل ممارساتها لسلطاتها وان كان هذا هدفاً يرضي طموح الافراد للمحافظة على حقوقهم وحرياتهم الا انه لايومن متطلبات تحقيق المصلحة العامة لاسباب في مقدمتها انه يستحيل على المشرع ان يتصدى لتنظيم النشاط الاداري بشكل تفصيلي بكل دقائقه وجزئياته.

Some Methods for Solving Initial and Boundary Value Problems with Nonlocal Conditions

The nonlocal conditions for the boundary or initial value problems appear when values of the function on the boundary or on the initial are connected to values inside the domain. Such problems are known as
nonlocal problem.The aim of this work is to study some types of nonlocal problems. This study includes the following aspects:

Solutions of Stochastic Ordinary Differential Equations Using Variable Step Size Runge-Kutta Methods

 The main objective of this thesis is divided in to three directions which are:
The first one is to study and overview the main and basic concepts of stochastic calculus, as well as, studying stochastic ordinary differential equations. The second objective is to study explicit stochastic Runge-Kutta methods, then generalize this scheme for semi-explicit, implicit and mixed schemes and study theirs numerical stability. The third objective is to introduce variable step size method for solving

On Stability of Multi Fractional Order Differential Equations with Constant Coefficient

         The use of fractional orders differential and integral operators in mathematical models has been increasingly widespread in recent years. The non-linear multi-term fractional (arbitrary) order differential equation has been considered. Its solution existences and uniqueness are proved by transform it into a linear system of equations.
