Abstract: In this thesis, we considered the problem of scheduling ???? jobs on a single machine. The aim of this study is to find the optimal and near optimal solutions for the sum of cost of total flow time and maximum late work with unequal ready time, this problem denoted by 1????????⁄Σ????????+????????????????????????=1⁄. The problem is strongly NP - hard, the branch and bound method was using to find optimal solution. Two lower bounds (LB1, LB2) are proposed each of them based on decompose the problem into two sub problems. The lower bounds of the problem is the sum of the lower bounds of the two sub problems. A heuristic which gives an upper bound in the root node of BAB algorithm was proposed, its effective in finding an optimal or near optimal schedule. Also, we proved some special cases of the problem which lead to optimal solution, three dominance rules were stated and proved. The results of extensive computational tests show that the proposed BAB algorithm is effective in solving problems up to (35) jobs at a time less than or equal to (30) minutes.We apply two local search methods to find near optimal solutions : Artificial Fish Swarm Algorithm (AFSA) and Fruit Fly Optimization Algorithm (FOA) .Computational experience found that these local search methods can solve the problem up to (6000) jobs with reasonable time, also found that : The AFSA has better results for the problem of size less than or equal to (35) jobs, but for the problems of size larger than (35) jobs, The FOA has the best results. All methods used in this research are programmed by using a programming language (MATLAB Language).

Abstract: This thesis deals with studying a new subject of a singularity perturbed ordinary di erential equations system. It is considered the foundation base to get a di erential algebraic equations, where the concept of singularity perturbed ODEs is explained. Thenit studies the ways to deal with the perturbation parameter ϵ through two case studies : The rst case : Is the study of behavior of solution for singularity perturbed ODEs when perturbation parameter 0

Abstract: The superconvergence of finite element solutions is surely an interesting and useful phenomenon in scientific computing of real world problems. The main objective of this thesis of is to construct a new approximation by post - processing an existing finite element solution so that the new approximation is closer to the exact solution than the existing finite element solution. The accuracy of finite element approximation can be improved to obtain superconvergence by applying some post process techniques to them. The - projection method is a such technique. The idea of the method is to make an - projection of existing finite element solutions to another finite element space associated with a coarse mesh. The advantage of this method is that it is easy to implement and can be applied to different elements with general meshes. We will apply the - projection method to obtain the super convergence for the different finite element approximations of the second order elliptic problem. The finite element methods involved are the conforming finite element method and the nonconforming finite method for the second order elliptic problem.

Abstract: In this thesis, we define contractive mapping, uniformly continuous mapping, ( ) uniformly locally contractive mapping, chainable fuzzy normed space, chainable intuitionistic fuzzy normed space and IFNS contraction mapping and also prove a fixed point theorems in fuzzy normed spaces and intuitionistic fuzzy normed spaces.In addition, in this thesis, we establish common fixed point theorems for mappings by using the concept of commuting mappings, weakly commuting mappings, weakly commuting mappings, compatible mappings, reciprocally continuous mappings, subcompatibility mappings and occasionally weakly compatible mappings in fuzzy normed spaces and intuitionistic fuzzy normed spaces.
