The dependence of scattering length on van der Waals interaction and on the reduced-mass of the system in two-atomic collision at cold energies
Hasi Ray
The static-exchange model (SEM) and the modified static-exchange model (MSEM) recently introduced by Ray [1] is applied to study the elastic collision between two hydrogen-like ato…
A study of state variable participation in limit-cycle of induction motor
Krishnendu Chakrabarty, Urmila Kar
The paper presents bifurcation behavior of a single phase induction motor. This paper also attempts to discuss the bifurcation behavior of the system based on the evolution of diff…
Stabilization of unstable periodic orbits in dc drives
Krishnendu Chakrabarty, Urmila Kar
Electric drive using dc shunt motor or permanent magnet dc (PMDC) motor as prime mover exhibits bifurcation and chaos. The characteristics of dc shunt and PMDC motors are linear in…
The effect of long-range forces on cold-atomic interaction: Ps-H system
Hasi Ray
The s-wave elastic phase-shifts and s-wave elastic cross sections are studied to find the effect of long-range forces on cold-atomic interactions using a modified static-exchange m…
