In this research work, the main task is to increase the DC open loop gain of a CMOS
operational amplifier for biomedical applications. It involves three basic concepts,
theoretical calculation, design, simulation, and ...
The present project work has mainly focused on reviewed structural and optical properties of
pure and Al, Cu doped Tin oxide (SnO2) Nanoparticles. The structure and nature of SnO2
Nanoparticles with different percentage ...
Superconductivity is a phenomenon that is seen in a few different elements and com pounds which is defined by the charge-carrying Fermions that condense into a Bose Einstein condensation. The main objective of this research ...
In this project, we successfully study the class of generalized non expansive mappings. We also
study s-iteration method for approximation for fixed points of generalized non-expansive
mappings which is faster than ...
In this project, we used the variational iteration method (VIM) to find the approximate
solution of linear and nonlinear Volterra Fredholm integro- ordinary differential
equations of the second kind. The reduction in ...
In this project, we apply the combination of Elzaki transform and homotopy perturbation method
(ETHPM) to solve nonlinear fractional heat -like equations and system of equations. The linear term in
the equation can be ...
In this project we solve solving some families of fractional order partial differential
equations using Laplace transform Homotopy Perturbation methods. The aim of the
methods is to find series analytic approximate ...
In this poject, we understand the new equational class of algebra which we call MS-almost
distributive lattice (MS-ADL) as a common abstraction of De Morgan ADLs and Stone
ADLs. We observed that the class of MS-ADLs ...
O. integrifolia is one of the medicinal plants used traditionally for the treatment of different
diseases. This study is intended to identify the phytochemical constituents and to evaluate the
antibacterial and antioxidant ...
A simple, versatile and selective cyclic voltammetry method for simultaneous determination of
paracetamol and amoxicillin on poly (DHRPCO)/GCE has been developed. The good potential
separation between the oxidation ...
This study investigates the extent of solar ultraviolet radiation (UVR), wavelength ranges
