In this work we use complex Lagrangian technique to obtain Noether-like operators and the associated conserved quantities of an Euler-Lagrange (EL) system. We show that the three new conserved quantities namely, Noether conserved quantity, Lie conser

In this work, we present in detail a novel approach to solve the time-dependent Schrödinger equation in the momentum space (TDSE- ). It is based on the expansion of the electron wavepacket and the nonlocal interacting Coulomb potential in a Coul

The challenging and pervasive issue associated with information exchange is inferential disclosure. It occurs in the following three situations: (1) the exchanged data correlate with publicly available information, (2) the exchanged data comprise pat

We proposed an algorithm for modeling the average (monochromatic) light attenuation coefficient and predicting the euphotic zone in shallow waters. Our algorithm uses Kalman filter and Kalman smoother to preprocess experimental data and utilizes Expe

We perform an approximate symmetry classification of the hyperbolic heat equation with variable parameters. It is found that its approximate symmetry Lie algebra is infinite-dimensional. We obtain optimal systems of one-dimensional subalgebras of som

The pressure–velocity formulation of the Navier–Stokes (N–S) equation is solved using the radial basis functions (RBF) collocation method. The non-linear collocated equations are solved using the Levenberg–Marquardt method. The primary novelt

The notions of partial Lagrangians, partial Noether operators and partial Euler–Lagrange equations are used in the construction of first integrals for ordinary differential equations that need not be derivable from variational principles. We obtain

We provide accurate, non-perturbative, semi-analytical solutions to a constrained fourth-order integro-differential equation derived by Djorjevic and Vukobratovic [On a steady, viscous flow in two-dimensional channels, Acta Mech. 163 (2003) 189–205
