MHD Free Convection Flow of Viscoelastic Fluid Through a Vertical Porous Plate with Thermal Conductivity under Soret-Dufour Influence

A. S. Idowu*, Abdulwaheed Jimoh, Ahmed Lukman Olalekan

A study of MHD heat and mass transfer of viscoelastic fluid past a porous plate with thermal conductivity under soret-dufour effect is investigated. The governing boundary-layer equations are formulated with appropriate boundary conditions. The Roseland diffusion approximation is used to analyze the radiative heat flux and it is appropriate for non-Scattering media. The governing boundary layer eq...

Gronwall-Bellman-Bihari Type Integral Inequalities of a Certain Class of Nonlinear Second Order Differential Equations

I. Fakunle*, P. O. Arawomo, B. D. Ogunbona

In this paper, we obtain nonlinear integral inequalities similar to Gronwall-Bellman-Bihari type. These inequalities are used to establish the boundedness and asymptotic behaviour of solutions of certain class of nonlinear second order differential equations. An example where f is a singular function is presented to show the application of our main results.

Design and Implementation of a Mobile Voice Assistant System for the Visually Impaired

A. O. Babatunde*, Olatinwo Suhurat Ikeola, G. B. Balogun, Mohammed Ahmed Adeola

Voice assistant systems are now becoming the newest technology in human computer interaction. However, the use of voice assistant systems has not been fully explored to help visually impaired individuals get the best out of their mobile devices as there have been challenges revolving around privacy and ease of use. The system was implemented using Kotlin for Android apps to work offline facilitati...
