Application of ultrasonic waves coupled with functional link neural network for estimation of carrageenan concentration

In this paper, a simple functional link neural network (FLNN) model is developed for the quantification of polysaccharides using ultrasonic waves. Every material has its own intensity to absorb the sound waves. The sound absorption capability of Carrageenan is based on its concentration in the solution. The sound pressure leave obtained from the one third octave band frequency spectrum is given as input to the FLNN and...

A quadratic based integration scheme for the solution of singulo-stiff differential equations

In this term paper, we designed a quadratic based integration scheme for the solution of initial value problem (IVPs) in ordinary differential equation (ODEs). This was achieved by considering the rational interpolating operator      satisfying          A class of rational integrator formula given...

Extraction of zinc (II) by triphenylphosphite (TPP) in hydrochloric acid: Kinetics and mechanism

The extraction of Zinc (II) in chloride medium with triphenyl phosphite (TPP) in kerosene has been investigated under different experimental conditions in order to have a better understanding of the extraction mechanism. The extraction yield was found to depend on the concentrations of Zinc (II) and TPP, and pH. The extraction yield can easily be predicted based on an established linear expression. The effect of...
