A New Subclass Of Starlike Harmonic Functions Defined By Subordination, Serkan Çakmak, Sibel Yalçın, Şahsen Altınkaya Jan 2020

A New Subclass Of Starlike Harmonic Functions Defined By Subordination, Serkan Çakmak, Sibel Yalçın, Şahsen Altınkaya

Al-Qadisiyah Journal of Pure Science

In this current work, by using a relation of subordination, we define a new subclass of starlike harmonic functions. We get coefficient bounds, distortion theorems, extreme points, convolution and convex combinations for this class of functions. Moreover, some relevant connections of the results presented here with diverse known results are briefly denoted.


The New Combination Of Semi-Analytical Iterative Method And Elzaki Transform For Solving Some Korteweg-De Vries Equations, Areej Salah Mohammed Jan 2020

The New Combination Of Semi-Analytical Iterative Method And Elzaki Transform For Solving Some Korteweg-De Vries Equations, Areej Salah Mohammed

Al-Qadisiyah Journal of Pure Science

The purpose of this research applied a method that includes the combination of an iterative method (Temimi and Ansari method (TAM)) and a new transform called the Elzaki transform (ET )for some Korteweg-de Vries (Kdv) equations. The TAM was present as a basic tool for solving Kdv equations with Elzaki transformation in the associated nonlinear equations because the Elzaki transformation cannot deal with nonlinear terms. It has been proven that the use of this method can be more reliable, accurate and fast if it has been using analytical methods alone.


Ranking Function Application For Optimal Solution Of Fractional Programming Problem, Rasha Jalal Mitlif Jan 2020

Ranking Function Application For Optimal Solution Of Fractional Programming Problem, Rasha Jalal Mitlif

Al-Qadisiyah Journal of Pure Science

The aim of this paper is to suggest a solution procedure to fractional programming problem based on new ranking function (RF) with triangular fuzzy number (TFN) based on alpha cuts sets of fuzzy numbers. In the present procedure the linear fractional programming (LFP) problems is converted into linear programming problems. We concentrate on linear programming problem problems in which the coefficients of objective function are fuzzy numbers, the right- hand side are fuzzy numbers too, then solving these linear programming problems by using a new ranking function. The obtained linear programming problem can be solved using win QSB program (simplex …


Regional Boundary Asymptotic Gradient Full Order Observer Via Internal Region, Raheam A. Al-Saphory, Zinah A. Khalid Jan 2020

Regional Boundary Asymptotic Gradient Full Order Observer Via Internal Region, Raheam A. Al-Saphory, Zinah A. Khalid

Al-Qadisiyah Journal of Pure Science

The purpose of this paper is to deals with the problem of regional boundary asymptotic gradient full order observer (-observer) concept by using internal regional case. Thus, we study the relation between this notion and the corresponding asymptotic detectability and sensors. More precisely, various important results have been examined and explored concern an extension of an approach which enables to reconstruct the gradient of current state from internal region. In addition, it has been shown that the characterization of -observability under which conditions to be achieved. Finally, we have illustrate that there is a dynamical system which does not represent …
