Tripled Fixed Point Theorems in Partially Ordered G-Metric Space

S. A. Aniki*, M. Raji, F. Adegboye, E. E. Aribike, K. Rauf

Tripled fixed point theorem is an improvement to coupled fixed point. In this manuscript, we prove the existence and uniqueness of tripled fixed point for mixed monotone mapping satisfying nonlinear contractions in the framework of partially ordered G-metric space. Our results generalize and improve some results in the literature.

Comparison between Taylor Series and Picard Method of Successive Approximation in Solving First Order Ordinary Differential Equation

S. A. Onitilo*, D. O. Daniel

In this paper, Taylor series method and Picard's method of suc-cessive approximation is being compared with their exact solutionof first order ordinary di erential equation. For numerical anal-ysis of the methods, four examples are considered. The resultsobtained are compared with their corresponding exact solutions.The results confirmed the e ective and ease of using Picard'smethod of successive ...

Performance Analysis of GPON-FTTx

O. A. Tiamiyu*, S. O. Onidare, A. O. Babatunde, A. O. Ajagbe, A. A. Ayeni, H. B. Akande

The demand for data services and necessary bandwidth have grown rapidly because of new telecommunications services like HDTV via the Internet, video on demand, etc. An increase in demand for broadband connection from private homes, companies, etc. leads to an increase in bandwidth demand in the access domain. Issues associated with copper cables being used for transmission are quite enormous, from...

Concerning Certain Finite Groups and the Elgamal Cryptosystem

S. M. Tudunkaya*

This paper presented a modification of the ElGamal cryptosystem with the aid of finite multiplicative groups of rhotrices defined over Zp for a prime p: This system may have an additional advantage of higher security.

Modeling The Fluid Flow for Seepage Problem: A Crank-Nicolson Approach

A. A. Hassan*, I. O. Abiala, J. S. Aroloye

The two-dimensional Laplace equation (which models the fluid flow of the seepage problem) was solved by a finite difference method, which is the Crank-Nicolson Method (CNM) subject to some boundary and initial conditions. We compared the numerical results of CNM to the Alternating Direction Explicit Finite Difference Scheme (ADES). First, we derived the finite differential form of the implicit, ex...

Systolic Array Residue Number System Based Smith-Waterman Algorithm

Hassan Kehinde Bello*

Smith-waterman algorithm (SWA) is widely used in computational biology. It is regarded as the most accurate sequence alignment algorithm on state-of-the-art (SOA). However, the algorithm is devoid of highspeed in term of performance. Evidence showed that various platforms have been used to implement the algorithm in order to improve the poor speed of operation, such as systolic array (SA) implemen...

On The Strength of Agreement Between Students’ Initial and Final Academic Performances In Nigeria University System

A. W. Banjoko*, Yahya W. B., H. S. Abiodun, M. O. Adeleke, B. Afolayan, M. K. Garba, Olorede K. O., Dauda K. A.

This paper examines the strength of agreement between academic performances of students after their first and final years in the University. Academic performances of a total of 886 students that were admitted into various academic programs in the Faculty of Science, University of Ilorin, during the 2008/2009 academic session were followed-up to their year of graduation in 2012. Information on the ...

Selecting Best Arima Model for Poison Data at Different Parameter Values

I. Akeyede*

A problem occurs when poison data have to be modeled. The number of counts in a certain period can only be an integer that is why the commonly used Autoregressive Moving Average (ARMA) model in time series, which assumes stationarity, seems not very useful anymore, simply because there are some associated problems like outlier and over dispersion that can be encountered in the poison data. For thi...

Mathematics Teaching as a Fundamental Tool for Self-Reliance and National Development

Khadijat Saka AMEEN*, Semiu Ayinla SALAWU, Saidat Morenike ADENIJI

Mathematics teaching is an interaction between the teacher and the learners that leads to acquisition of desirable mathematical knowledge, ideas and skill. These mathematical ideas, knowledge and skills form the basic essential tools for human and national independence. This paper therefore discusses the concept of self-reliance, the concept of National development, the concept of Mathematics teac...

Evaluating Accessibility of Healthcare Delivery in Edo South Senatorial District using Kernel Density Estimation

O. Ikpotokin*, A. A. Idowu, E. M. Ogbeide

Sound health is a major requirement for living essential and productive life. Meanwhile, due to lack of access to quality healthcare delivery, some treatable health conditions often goes untreated and which has in turn reduced productive life of many generations. Kernel Density Estimations (KDE) and Geographic Information System (GIS) based spatial analytical tools and nearest neighbor methods wer...
