“…These problems were known to be common in the fields of natural sciences, engineering, medical sciences, fluid mechanics, aerodynamics, magnetic dynamics, diffusion theory, reaction diffusion, light emitting waves, electron plasma waves, communication networks, plasma dynamics, refined gas dynamics, mass transport, plastics, chemical reactor theory, oceanography, meteorology, electricity current, ion acoustic waves plasma and several physical modelling techniques (see, [2,4,9,14,15,18,24,25,26,27]). Lately, singularly perturbed problems, particularly with the nonlocal boundary condition and boundary layers have been studied by several researchers (e.g., [1,7,8,10,11,12,16,17,19,20,23] and the references therein). Bakhvalov used a special transformation in numerical solution of boundary solid problems [5].…”
