Sophie M. Moufawad, Nabil R. Nassif, Faouzi Triki
Simultaneous use of partial differential equations in conjunction with data analysis has proven to be an efficient way to obtain the main parameters of various phenomena in differe…
Newton Type Methods for solving a Hasegawa-Mima Plasma Model
Sophie M. Moufawad, Nabil R. Nassif
In [1], the non-linear space-time Hasegawa-Mima plasma equation is formulated as a coupled system of two linear PDE's, a solution of which is a pair (u, w). The first equation is o…
A Finite-Element Model for the Hasegawa-Mima Wave Equation
Hagop Karakazian, Sophie Moufawad, Nabil Nassif
In a recent work, two of the authors have formulated the non-linear space-time Hasegawa-Mima plasma equation as a coupled system of two linear PDEs, a solution of which is a pair $…
Strong and Weak Solutions to the Hasegawa-Mima Equation with Periodic Boundary Conditions
Hagop Karakazian, Nabil Nassif
The two dimensional Hasegawa-Mima (HM) equation describes the time evolution of drift waves in magnetically-confined plasma. Several authors have t…
