This equation is a nonlinear equation. The main objective in this paper is to find an exact solution of ZK-equation using Adomain decomposition method. An exact solution of ZK(n,n,n) is derived by Adomain decomposition method. The solution of types ZK(2,2,2) and ZK(3,3,3) are presented in many examples to show the ability and efficiency of the method for ZK-equation. The solution is calculated in the form of convergent power series with easily computable components.</p> Fadlallah Mustafa Mosa Eltayeb Abdellatif Mohamed Yousif ##submission.copyrightStatement## 2020-03-24 2020-03-24 1 11 10.9734/arjom/2020/v16i430182 On the Hyper-Zagreb Index of Some Graph Binary Operations <p>This study looked at Graph theory as it is an important part of mathematics. Topological indices are numerical parameters of a graph which describe its structure, they have many applications as tools for modeling chemical and other properties of molecules. In this paper, we presented some exact formulas of the Hyper-Zagreb index for some special graphs and some graph binary operations such disjunction G v H, symmetric difference G H, and tensor product G <br> H of graphs.</p> Mohammed Saad Yahya Al-Sharafi Mahioub Mohammed Shubatah ##submission.copyrightStatement## 2020-03-30 2020-03-30 12 24 10.9734/arjom/2020/v16i430183 Modelling Building Renovation Using PERT <p>Effective project management techniques are critical to managers and decision makers in handling projects in today’s competitive environment. It is required that with such techniques, managers can carry out projects and complete them within specified time and resource constraint. This research considers the application of Program Evaluation and Review Technique (PERT). PERT was used to analyze data collected from Mega Star Technical and Construction Company in charge of the renovation/building construction of renovaworks at 48 Forces Avenue, Old GRA, Port Harcourt, Nigeria. The technique was used to obtain the network diagram, critical path, expected completion time for the project and the probability of completion within a required date. Ms Project version (2013) software was also used for the analyses. Results obtained revealed that the project can be completed within record time and possess a very high probability of completing the project within a stipulated date.</p> Nsikan Paul Akpan Gregory Okiemute Agadaga ##submission.copyrightStatement## 2020-04-01 2020-04-01 25 38 10.9734/arjom/2020/v16i430184 Some Properties and Estimation of Parameters for the Five Parameter Type I Generalized Half Logistic Distribution under Complete Observation <p>This paper is a further study of the five parameter type I generalized half logistic distribution. We derived some properties of the distribution. Estimation of the parameters of the distribution under complete observation was studied using the maximum likelihood method. To assess the flexibility of the distribution, it was applied to a real lifetime data and the results when compared to the sub-models showed that the five parameter type I generalized half logistic distribution performed best.</p> O.
