in this paper, the reduced dierential transform method is investigated fora nonlinear partial dierential equation modeling nematic liquid crystals, itis called the hunter-saxton equation. the main advantage of this methodis that it can be applied directly to nonlinear dierential equations withoutrequiring linearization, discretization, or perturbation. it is a semi analytical-numerical metho...

Rising energy costs have spawned renewed interest in improving methodologies for the synthesis, design and/or retrofitting of separation rocesses. It is well known that energy use in many process industries is dominated by separation tasks—particularly distillation. In this work, the hortest stripping line approach recently proposed by Lucia, Amale, & Taylor (2006) is used to find minimum energ...
