Fixed Point Results on Certain Contractive Conditions in Complete G-Metric Space

O. R. Zubair^*, R. U. Kanu, B. Y. Aiyetan, Kamilu RAUF

In this work, results on the existence and uniqueness of a fixed point in a complete G-metric space are obtained. Ciric, λ-generalized and Geraghty contractions formulated in G-metric settings are involved by applying Picard iterative procedure. Our results extends and also improve some results in the literature.

Finite geometries and Finite quantum systems: Duality between lines in phase space and mutually unbiased bases in Hilbert space

Oladejo S. O.^*, Olupitan T., Bukar A. M.

In this work, we focus on finite quantum systems with variables in Zd and finite geometry Gd where d is a prime integer. In it, we confirmed the existence of duality between mutually unbiased bases in Hilbert space of a finite quantum system and lines in phase space.

Application of Assignment Model in Optimizing Cost of a Building Project

Nyor Ngutor^*, Olaniyan Toyin, Ladi Kevin

The study sought to minimize the total cost of building a three bed-room Detached House in Minna. An Assign ment problem was formulated and using Hungarian solu tion method, a realistic result was obtained. The sighting study with unpopular scenario in building recommended the sum of N3,885,000 which can be used to build a house of the type and specifications as provided in the study.

Efficiency of Simpson’s Rule; A Case Study of Unilorin Land Area

Ayinla Ally Yeketi^*, Isola Olatomiwa Oluwadamilare

Simpson’s rule, a numerical integration technique, provides anefficient method for estimating the area of an irregularly shapedlarge landmasses when analytical solutions are impractical. Thisstudy applies Simpson’s 13 , 38 and hybrid rules to determine thearea of the University of Ilorin landmass. The hybrid method,combining the 13 and 38 rules, proves to be more efficient due to itsflexibility wi...

Some generalized k-Fractional companions of Hadamard's inequality

Hussain R.^*, Kehkashan B., Ali A., Latif A., Kamilu RAUF

The present study deals with the derivation of some new companions of Hadamard's inequality of fractional type by means of generalised convex functions, viz. h-convex functions, s-convex functions and also by co-ordinated h-convex functions on a rectangle from the plane R2.

HYDROMAGNETIC BOUNDARY-LAYER FLOW OF A NANOFLUID PAST A STRETCHING SHEET EMBEDDED IN A DARCIAN POROUS MEDIUM WITH RADIATION

Yusuf A^*, Aiyesimi Y. M, Jiya M.

The problem of laminar fluid flow which results from the stretching of a flat surface in a nanofluid has been obtained using the Adomian Decomposition Method. The model used for the nanofluid was presented in its rectangular form. The model is considered in a porous medium and incorporates the magnetic effect, thermal radiation effect and the effect of Brownian motion and thermophoresis. A similar...

Dynamics of Non-Newtonian Nano fluid Flow Past a Semi-Infinite Vertical Porous Plate Under the Influence of Lorentz Force and Soret-Dufour Mechanism

Ahmed Lukman Olalekan^*

This paper considered the boundary layer behavior, and e ects of magnetohydrodynamic (MHD) and viscous dissipation on the simultaneous ow of Casson and Walter-B viscoelastic nano uid past a vertical penetrable plate in the presence of heat generation, radiation, chemical reaction, Soret, and Dufour mechanism. The nature of Casson uids examined in the study are blood and uid juice. These two non-Ne...

A Three-Step Algorithm for Solving Second Order Ordinary Differential Equations

L. A. Ukpebor^*

A linear Multistep Method (LMM) of step length of three with six integrators and uniform order four through interpolation and collocation procedures were developed. The integrators are implemented on a Vanderpol’s oscillator Problem, stiff problem and, exponential problems. The results acquired compares satisfactorily with the existing method in the literatures. The properties of the integrators a...
