Awinawinsus@yahoo.com<p> Ordering is an important subject of learning; it has so many applications in day -to - day life. Hence, in this paper exact and general exact ordering methods are reviewed giving sample applications for them.</p> <p>Firstly, the exact ordering method is introduced and few theorems are given to assign the conditions needed to locate the position of a required object among a class of objects to be ordered in a certain manner in three classes.</p> <p>Secondly, the exact ordering method is generalized to any odd number of classes In both cases and if the required object class is put in the middle of other classes, then the required object will be located exactly in the middle of all objects provided that we arrange the objects orderly in three classes in the first case and in ones in the second general case and where certain defined steps are to be followed.In general steps are required to determine the required object exactly and where is the odd number of classes.</p> <p>Making the subject more interesting, deeper, and handled in a sophisticated manner, through the introduction of exact ordering operators, is then exposed to.</p> <p>Finally, few different applications are suggested in physics, operational research, criminal investigation and in sorting files and postal mailing. A practical demonstration with playing cards is also mentioned.</p>2022-08-08T00:00:00+00:00##submission.copyrightStatement##http://scitecresearch.com/journals/index.php/jprm/article/view/2158Two Classes of Optimal Fourth-Order Iterative Methods Free from Second Derivative for Solving Nonlinear Equations2022-08-08T01:45:09+00:00Laila A. Alnaserlnaser@taibahu.edu.sa<p>This work proposes new fourth-order iterative methods to solve non-linear equations <em> </em> . The iterative methods proposed here are presented by modifications of a third-order iterative method to be two classes of optimal fourth order. Convergence analysis was done for the iterative methods proposed in this paper. Multiple numerical examples were taken to explain the accuracy and efficiency of the proposed iterative methods.</p>2022-08-08T01:45:09+00:00##submission.copyrightStatement##http://scitecresearch.com/journals/index.php/jprm/article/view/2150Idempotent Structures Of Semigroup Of Singular - Regular Matrices2022-10-27T16:38:00+00:00Adenike Olusola Adenijiadeniji4love@yahoo.com<p>Let S be a semigroup of singular matrices over a subset of the set of integers. The idempotent<br>elements of S are classified into tridempotent, fractional idempotent and skew idempotent<br>elements. Matrices are generally known to be non-commutative but an example of commutative<br>matrices is established in this work. Matrix multiplication and its axioms are employed<br>to establish the results. Regularity was first established and the condition for regularity of<br>each idempotent structure obtained is discussed. Some of the structures obtained are used to<br>establish bands of regular elements. The fractional component of S is obtained combinatorially<br>by choosing a number with its sign for every row of each matrix. There are m values of<br>matrices with first and second rows being equal, which are removed from the set since their<br>multiplication gives zero. The satisfaction of the condition for commutativity implies that all<br>the matrices have the same characteristic equation and all are of a specified order n. This is<br>evident in the fact that the product of the principal diagonal, D1 of matrix A is the same as<br>the product of the principal diagonal D2 of matrix B. Also, the product of the off- diagonal of<br>matrices A and B are the same.</p>2022-10-27T16:38:00+00:00##submission.copyrightStatement##http://scitecresearch.com/journals/index.php/jprm/article/view/2166On the Solutions of Systems of Rational Difference Equations2022-11-02T14:50:16+00:00E.

One way to present the drainage system is to use graphs. A graph is defined as a set of pairs (𝑉, 𝐸), which in this case 𝑉 is a finite non-empty set whose elements are called vertices and 𝐸 is a set (possibly empty) of unsorted pairs connecting a pair of vertices called sides. In this study, a drainage system in Madiun City, Indonesia, will be presented in a graph using the Graphviz application. Graphviz is software that can be used to create a visualization of structured data such as network images.</p>2022-08-08T01:44:37+00:00##submission.copyrightStatement##
