Hydromagnetic Peristaltic Transportation With Porous Medium Through An Asymmetric Vertical Tapered Channel And Joule Heating, S. R. Kumar
Applications and Applied Mathematics: An International Journal (AAM)
The present paper deals with a theoretical investigation of the hydromagnetic peristaltic transportation with porous medium through coaxial asymmetric vertical tapered channel and joule heating which has been studied under the assumption of long wavelength approximations. Exact analytical expressions of axial velocity, volume flow rate, pressure gradient, temperature and heat transfer coefficient at both walls were calculated. The effects of various emerging parameters, Hartmann number, Non-uniform parameter, Prandtl number, Heat generator parameter, Brinkman number, Porous parameter are discussed through the use of graphs. We notice from the figures that the temperature of the fluid increases in the entire vertical tapered …

A Mathematical Model For Micropolar Fluid Flow Through An Artery With The Effect Of Stenosis And Post Stenotic Dilatation, R. B. Vijaya, K. M. Prasad, C. Umadevi
Applications and Applied Mathematics: An International Journal (AAM)
The effects of both stenosis and post stenotic dilatation have been studied on steady flow of
micropolar fluid through an artery. Assuming the stenosis to be mild, the equations governing the
flow of the proposed model are solved. Closed form expressions for the flow characteristics such
as velocity, pressure drop, and volumetric flow rate, resistance to the flow and wall shear stress
are derived. The effects of various parameters on resistance to the flow and wall shear stress
have been analyzed through the graphs. It is found that the resistance to the flow increases with
the height and length of …
Upper, Lower Solutions And Analytic Semigroups For A Model With Diffusion, Yannick T. Kouakep
Upper, Lower Solutions And Analytic Semigroups For A Model With Diffusion, Yannick T. Kouakep
Applications and Applied Mathematics: An International Journal (AAM)
In this discussion we consider an autonomous parabolic epidemic 2-dimensional system modelling the dynamics of transmission of immunizing diseases for a closed population into bounded regular domain. Our model takes into account diffusion of population with external influx as well as one class of infected individuals. We study the well-posedness two-component diffusion equations including external supplies with Neumann conditions using upper/lower solutions and analytic semigroups. In case of constant population or not, with non-oscillatory solution and constant diffusion, this problem admits travelling wave solutions whose minimum wave speed is surveyed here.

Color Image Encryption And Decryption Using Hill Cipher Associated With Arnold Transform, Rakesh Ranjan, R. K. Sharma, M. Hanmandlu
Applications and Applied Mathematics: An International Journal (AAM)
Image security over open network transmission is a big concern nowadays. This paper proposes another methodology for color image encoding and decoding using two stage Hill Cipher method which is connected with Arnold Transformation. The forgoing created a strategy for encryption and decryption of color image information and touched on just the premise of keys. In this plan, keys and the agreement of Hill Cipher (HC) are basic. Moreover, keys multiplication (pre or post) over an RGB image information framework is inevitable to know to effectively decrypt the first image information. We have given a machine simulation with a standard …
