recent studies on wavelet transform and fractal modeling applied on mammograms for the detection of cancerous tissues indicate that microcalcifications and masses can be utilized for the study of the morphology and diagnosis of cancerous cases. it is shown that the use of fractal modeling, as applied to a given image, can clearly discern cancerous zones from noncancerous areas. in this paper, f...

in this paper, shielding effectiveness (se) of a perforated enclosure with imperfectly conducting walls is evaluated. to this end, first, an accurate numerical technique based on method of moments (mom) ispresented. in this method, lossy metallic walls of the enclosure are replaced by equivalent electric surfacecurrent sources. then, the impedance boundary condition on the imperfectly conductin...

The advancement of nanofluid technology has become an essential tool for investigating thermal conductivity enhancement, which is highly valuable industrial and engineering applications in many fields including mathematics, physics, engineering, materials science. This analysis focuses on 3-D boundary-layer flow over a rotating disk by incorporating chemical reaction radiations effects. One aim...

This work aimed to establish a numerical simulation of kerosene oil as host Casson fluid flowing around cylindrical shape with an applied magnetic field crossing through it, under constant wall temperature boundary conditions. Nanoparticles zinc, aluminum, and titanium oxides were included reinforce its thermal characteristics. The governing model was established based on the Tiwari Das model. ...

This study emphasis on the analysis of boundary layer flow viscoelastic fluid with microrotation moving over a porous horizontal circular cylinder. The model problem is based Navier Stokes equations which involved continuity, momentum and micro inertia equations. mentioned are first undergo Boussinesq approximation before transforming to non-dimensional form in partial differential system. Sinc...

The impact of buoyancy on axisymmetric radiative Powell-Exring fluid flow towards a radially stretched surface is examined. To analyze the heat and mass transfer characteristics, thermal radiation, joule heating chemical reactions are incorporated to flow. equations governing obtained with help boundary layer approximation. modeled coupled PDE system transfigured as ODE by exerting adequate sim...
