This paper describes the development of encryption algorithms using the magic square of order 5 and Multi-level keys with the addition of Matrix keys to increase implementation speed and complexity. This work relied mainly on the magic sum and some…
The unsteady two-dimensional magnetohydrodynamic heat and mass transfer free convection flow of an incompressible viscous electrically conducting polar fluid through a porous medium past a semi-infinite vertical porous moving plate in the presence of…
An analysis of free convection and mass transfer unsteady magnetohydrodynamic flow of an electrically conducting viscous incompressible fluid past an infinite vertical porous plate is presented by taking into account the Dufour and Soret effects.…
Context-awareness is becoming a key aspect of mobile learning systems. In fact, an efficient mobile learning system has to be sensitive to the context that characterizes the interactions between humans, applications and the surrounding environment.…
The heat and mass transfer characteristics of the nonlinear, unsteady, radiative MHD boundary layer slip flow of a chemically reacting fluid past an infinite vertical porous plate are taken into account in this study. The effect of physical…
Technology advent has been transforming students’ perceptions and preferences mostly on how they acquire information and learn. The way students perceive e-books and print books significantly influences the format they prefer to use for academic…
In this article, we discuss the outbreak of the Covid-19 pandemic as abiopolitical challenge that – along the lines of the contemporary academicdebate on biopower – may be approached through the concepts ofsovereignty and governmentality. Within this…
According to the current international climate change regime, countries are responsible for greenhouse gas (GHG) emissions that result from economic activities within their national borders, including emissions from producing goods for export. At the…
In an effort to find out the best suitable application of mobile learning, several research works are undertaken till date. A review of related papers unveiled that mobile devices act better as a supporting media in teaching and learning scenario.…
