Cardiovascular diseases (CVDs) are the world's leading cause of death; therefore cardiac health human heart has been a fascinating topic for decades. The electrocardiogram (ECG) signal is comprehensive non-invasive method determining health. Various practitioners use ECG to ascertain critical information about heart. In this paper, noisy denoised based on Discrete Wavelet Transform (DWT) optimi...

rain modeling in recent years has been of great importance in water resource management and its function in long term and short term planning, especially its great effect on agricultural economy. to reach to good results box-jenkins model is much more efficient. the writers of this article have used the data collected in tabriz and oroumiyeh stations in a fifty year period and then presented th...

viscosity (µ) and density (ρ) are important physical roperties for analysis of membrane processes performance and for designing a new membrane process. in addition, the energy requirement for fluid pumping is depend on these two physical properties magnitiude. in this study, firstly, the effects of different process factors such as transmembrane pressure (51, 101, 152, 203 and 253 kpa), tempera...

The presence of coal in complex structures featuring sandstone reservoirs seriously hinders reservoir characterization and the identification fluids subsurface formations. Coal can strongly obscure reflections from sandstone, easily leading to false bright spots during exploration; thus, their boundaries cannot be accurately described. Furthermore, layers intercalated with thin seams form compo...

optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of zno semiconductor. in optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the bruggeman homogenization formalism. zno nano rods (zonrs) as a nucleus layer were fabricated on the indium tin oxide (ito) by chronoamperometry (ca) in a...
