This method is called the Shehu transform homotopy method (STHM). This method is used to solve the time-fractional partial differential equations (TFPDEs) with proportional delay. The fractional derivative is described in Caputo's sense. The solutions proposed in the series converge rapidly to the exact solution. Some examples are solved to show the STHM is easy to apply.</p> Ahmad. A. H. Mtawal , Sameehah R. Alkaleeli Copyright (c) 2020 Ahmad. A. H. Mtawal , Sameehah R.

Finally, we give some figures.</p> Khalid D. Abbood Copyright (c) 2020 Khalid D.

The first objective is to study the relationship between the density property and some modules in detail, for instance; semisimple and divisible modules. The Addition complement has a good relationship with the density property of the modules as this importance is highlighted by any submodule N of M has an addition complement with Rad(M)=0. The second objective is to clarify the relationship between the density property and the essential submodules with some examples. As an example of this relationship, we studied the torsion-free module and its relationship with the essential submodules in module M.</p> Majid Mohammed Abed, Fatema F.

However, the classification of such rings via a well-known structure of zero divisors has not been done in general. More specifically, the automorphisms of such classes of rings have not been fully characterized. In this paper, we obtain a more complete<br />illustration of the automorphisms of zero divisor graphs of finite rings in which the product of any zero divisor</p> Lao Hussein Mude, Owino Maurice Oduor, Ojiema Michael Onyango Copyright (c) 2020 Lao Hussein Mude, Owino Maurice Oduor, Ojiema Michael Onyango Mon, 24 Aug 2020 00:00:00 +0000 An Estimation of Parameters For Exponentiated Burr Type XII Distribution Based on Ranked Set Sampling <p>The aim of this paper is to estimate the parameters of exponentiated Burr type XII distribution (EBXII) based on ranked set sampling (RSS) technique, and also simple random sampling(SRS) is provided by the method of maximum likelihood. Fisher information matrix for both (SRS) and (RSS) for the unknown parameters are derived. Simulation study compared between the estimators of both methods in terms of their biases, mean square errors, and efficiencies. It is shown that the estimators based on RSS are more efficient than those of SRS.</p> Abdallah Abdelfattah, Nagwan Reyad Elshendidy Copyright (c) 2020 Abdallah Abdelfattah, Nagwan Reyad Elshendidy Sat, 15 Aug 2020 00:00:00 +0000 On the existence of continuous solutions of a nonlinear quadratic fractional integral equation <p>We prove an existence theorem for a nonlinear quadratic integral equation of fractional order, in the Banach space of real functions defined and continuous on a closed interval. This equation contains as a special case numerous integral equation studied by other authors. Finally, we give an example for indicating the natural realizations of our abstract result presented in this paper.</p> Wagdy G. El-Sayed, Mahmoud M. El-Borai, Mohamed M.A. metwali, Nagwa I.

In this paper, a modern method to find the square root of the complex number has been analyzed, and some examples on the subject were presented.</p> Ahmed A. Almoselmawy Copyright (c) 2020 Ahmed A.

The Laplace transform was used in this modification to eliminate the linear differential operator in the differential equation. The convergence of the solution was discussed according to the modification proposed. To illustrate this modification some examples were presented.</p> Alaa K. Jabber Copyright (c) 2020 Alaa K.
