Analytical and Approximate Solutions for Volterra Integro-Differential Equations and It’s Applications
The main objective of this thesis is to study and solve the Volterra integral and integro-differential equation and some scientific models for real life problems. This objective may be divided into three sub objectives, as follows:
Solution of Fuzzy Network Problems Using Statistical Methods
This thesis developed three defuzzification approaches to convert the coefficients and the variables of the fuzzy linear programming problems (FLPP) into crisp (deterministic) linear programming problems (CLPP) and obtain the critical path with the optimal completion time for the different fuzzy network problems.The three defuzzification approaches are based respectively on the philosophies of probability density function, ranking measures and the program evaluation and review technique (PERT).Finally, the critical path method (CPM) has been used to compare its
Approximate Solutions For Delay Differential Equations Of Fractional Order
The main theme of this thesis is oriented about two objects:
Numerical and Approximate Methods for Solving Stochastic Integral Equations
Stochastic and random integral equations are of great importance that may be used in modeling certain type of problems that contains random process and noise. Therefore, the main objectives of this thesis may be oriented as follows: The first objective is to study the theoretical side of stochastic calculus and stochastic processes, which include the basic definitions and fundamental concepts related to this topic, such as stochastic processes,stochastic differentiation and stochastic integration the existence and uniqueness theorem.
Approximation Method for Solving Fractional Order Variational Problems using Haar Wavelet
In this thesis, we present a clear procedure of solutions for the fractional variational problems via Haar wavelet technique. The fractional derivative is defined in the Riemann-Liouville sense.The main theme of this thesis is oriented about two objects:
مدى سلطة القاضي الاداري في توجيه الادارة العامة
لطالما كانت العلاقة بين الادارة والقضاء الاداري محكومة وفقاً لمبدأ الفصل بين السلطات الذي يقتضي ان لا تتدخل اي من السلطات في عمل السلطات الاخرى اعتماداً على التفسير السائد لذلك المبدأ لذلك فأن هذه الدراسة تهدف الى مدى امكانية التوفيق بين متطلبات مبدأ الفصل بين السلطات الذي يحظر على القاضي الاداري التدخل في عمل الادارة او الحلول محلها وبين مقتضيات مبدأ المشروعية الذي يقتضي توجيه الاوامر للإدارة لإخضاعها لحكم القانون واحترام حجية الشيء المقضي به ، كما انها تهدف الى القاء الضوء على التطورات الحديثة التي طرأت على تلك العلاقة وخصوصاً فيما يتعلق بسلطة الق

The aim of this work is to study some types of the fractional non-local problems.
Numerical Solution of Fractional Order Differential Equations Using Wavelets Methods
The main theme of this thesis is oriented about three objects:
Radiation Dose Assessment for Ionizing and Ultraviolet Radiations Using CR-39 , Lexan and LR-115 Nuclear Track Detectors
The aim of this study is the radiation dose assessment of gamma rays-γ and ultraviolet-UV radiation on nuclear track detector-NTDs types CR-39 , Lexan and LR-115 through measuring the absorbance-A by using uv-visible spectroscopy technique and measuring the spectral deviation of Fourier transform infrared- FTIR technique .The radiation response for gamma rays was measured at low dose range 1Gy to 10 Gy and high dose range 10 Gy to 195 kGy .There is gamma ray response for all NTDs used in this study .
