Gross misinterpretation of a conditionally solvable eigenvalue equation
(World Scientific, 2020-11-10)
We solve an eigenvalue equation that appears in several papers about a wide range of physical problems. The Frobenius method leads to a three-term recurrence relation for the coefficients of the power series that, under ...

Development of regression equations for estimating height and weight using body segments in Argentine children
(Elsevier Science Inc, 2019-01)
Objectives: Body weight and height measurements are essential in children for assessing growth and nutrition, for the calculation of medication doses, and for the effectiveness of medical interventions. When direct ...
Some qualitative properties of generalized Liénard's equation

This book is the result of research done in the last two years by the "Group of Nonlinear Analysis" (GANol) of the Faculty of Exact and Natural Sciences and Surveying of the National University of the Northeast (UNNE). ...
Analysis of the stability and dispersion for a Riemannian acoustic wave equation
(ELSEVIER SCIENCE INC, 2019-01-15)
The construction of images of the Earth's interior using methods as reverse time migration (RTM) or full wave inversion (FWI) strongly depends on the numerical solution of the wave equation. A mathematical expression of ...
