This work derives the Lagrangean hydrodynamic representation of the Dirac field that, by using the minimum action principle in the non-Euclidean generalization, can possibly lead to the formulation of the Einstein equation as a function of the fermion fie... see more

The bound state solution of the Dirac equation for generalized Pöschl-Teller and trigonometric Pöschl-Teller non-central potentials was obtained usingSUSY quantum mechanics and the idea of shape invariance potential. Theapproximate relativistic energy spe... see more

The radiation self-force of a point charge is obtained in a mathematically exact way in the framework of Distribution theory: the world line and the electromagnetic field of a point charge are treated as Distributions; the energy-momentum tensor of the po... see more

This paper concerns with the down-stream propagation of waves over initially still water. Such a study is relevant to generate waves of large amplitude in wave tankof a hydrodynamic laboratory. Input in the form of a time signal is provided at the wave-ma... see more

Charge transport phenomena can been tackled in silicon quantum wires using a subband hydrodynamic model. This has been formulated by closing the moment system derived from the Schödinger-Poisson-Boltzmann equations on the basis of the Maximum Entropy Prin... see more

Two simple, rapid, accurate and precise spectrophotometric methods have been developed for simultaneous estimation of Nimorazole and Ofloxacin from tablet dosage form. Method ? involves formation of ‘simultaneous equations’ at 304 nm (? max of Nimorazole)... see more

We solve the Dirac equation for the quadratic exponential-type potential plus Eckart potential including a Coulomb-like tensor potential with arbitrary spin–orbit coupling quantum number ?. In the framework of the spin and pseudospin (spin) symmetry, we o... see more

ExcerptModeling complex systems is basically a two-fold process. The first step involves formulation of the dynamical relations which usually takes the form of differential equations (DE) while the second step engages in determination of the relationship ... see more

Offshore spar platform is a compliant offshore floating structure used for deep water applications for drilling, production, processing, storage and offloading of ocean deposits. The offshore spar platform is modelled as a rigid body with six degrees-of-f... see more
