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

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.

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

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 .
