Polynomial Bounds for Bi-Univalent Functions Associated with Sigmoid Function and Q− Derivative Over a Chebyshev Polynomials

I. T. Awolere, A. M. Gbolagade*

This paper introduces a new subclass of the function class P of biunivalent analytic functions defined in the open unit disk, associated with a certain operator and the Sigmoid function via Chebyshev polynomials. Bounds for the initial coefficients are obtained for the defined class, along with results for the Fekete–Szeg¨o functional. Furthermore, by varying the parameters involved, several resul...

On the Nilpotent Fuzzy Subgroups of the Abelian Type: Z₃₂ × Z₂ⁿ, n ≥ 5

S. A. Adebisi*, M. Ogiugo, M. EniOluwafe

The extension of the finite nilpotent groups is now being diversified. As such, results up to two dimensions are now obtainable. In this paper, the fuzzy subgroups of the nilpotent abelian structure given by: Z32 × Z2n, the cartesian product of two abelian subgroups of orders 2n and 32 respectively for every integer n > 5 have been carefully studied and the explicit formulae for its number distinc...

An Extended 2-point Super Class of Block Backward Differentiation Formula with off-step Points for Solving Stiff Initial Value Problems

Hamisu Musa*, Ahmad Abubakar Umar

In this paper, we considered an extended 2-point Super class of block backward differentiation formula for solving stiff initial value problems (IVPs) and introduced two off-step points in it. The method produces two solution values together with two off-step points simultaneously at each iteration. The varying free parameter ρ is chosen in the interval (−1, 1) which leads to different forms of th...

Effect of Brownian Motion and Thermophoresis on Heat and Mass Transfer of a Three- Dimensional Casson Fluid Flow Over a Stretching Sheet with Velocity Slip

I. O. Abiala*, A. S. Odesola, O. J. Fenuga

This paper provides a numerical investigation on the effect of Brownian motion on the heat and mass transfer of a steady laminar MHD three-dimensional, Casson fluid flow over a surface which is stretched linearly in two lateral direction with convective surface boundary conditions. The governing Partial Differential Equations of the flow are transformed into a highly nonlinear coupled Ordinary Dif...

Phase-fitted partitioned Runge-Kutta methods for separable oscillatory Hamiltonian systems and related problems

J. O. Ehigie*, S. A. Okunuga, E. Ayeni

We present an approach for deriving some phase-fitted Parti tioned Runge-Kutta (PRK) methods for numerical integration of separable Hamiltonian and related systems. The approach constitute the modification of the existing PRK such that some parameters are modified to eliminate the phase-lag and the amplification error using the analysis of phase properties. The new coefficients are derived such th...

JUST-IN-TIME SCHEDULING PROBLEMS ON IDENTICAL PARALLEL MACHINES

M. O. Adamu*, Abass O.

Problems involving Just-In-Time (JIT) scheduling provide an interesting and difficult challenge, which is addressed critically within this paper. This study considers the scheduling of parallelidentical machines to maximize the (weighted) number of on-time jobs. This problem is known to be NP-complete. Three problems were dealt with in this paper. Two greedy heuristics with time complexity O(n log...

Result on the Existence and Uniqueness of the Fixed Point with Mann Iteration in a Complete G-Metric Space

A. A. Idowu*, B. Y. Aiyetan, Kamilu RAUF, L. Aminu

In this research, we prove the existence and uniqueness ofthe mixed point in a complete G-metric space using severalgeneralised contractive conditions formulated in G-metricsettings, taking Mann-iteration as our iterative procedure. Our results improve and extend some well-knownresults in the literature. We have utilized these conceptsto deduce that Mann iterative procedure is G-convergent,G-Cauch...

Mathematical Analysis of Draw-Down Level and Its Effect On Crop Yield

M. D. Shehu*, P. O. Evans, H. O. Ahmed, Adeniyi I. A.

In this paper, we formulated mathematical equations for ground water flow considering the Draw-down levels in an unconfined Aquifer system, using the parameters; well pumping rate, hydraulic conductivity, transitivity, radius of influence. Different draw-down levels for different wells were determined in an unconfined aquifer system. Relating the draw-down level to crop production (Maize yield) sh...
