The stability of the method may impose a strict mesh spacing, therefore a proper stabilized scheme, which is stable whatever spacing is used, has been developed.
This latter method was originally proposed as an 'exponential fitting' difference scheme by Allen and Southwell in [29] and subsequently referred to as an artificial diffusion stabilized scheme with 'optimal viscosity' by Brooks and Hughes in [18].

An h-convergence study and test problems for the three stabilized schemes are discussed.
Then, for systems with relaxed diffusion vector fields, a decentralized adaptive stabilizing scheme is proposed to ensure the boundedness in probability of all signals in the closed-loop system.
The technique is applied to obtain an (almost) globally stabilizing scheme for the vertical takeoff and landing aircraft with strong input coupling, and a controller for the chariot with the pendulum that can swing-up the pendulum from any position in the upper half plane and stop the chariot at any desired location.
Here, since the three-dimensional stress state is known, the calculations of cell traction forces is straightforward using Eq. 13, and since all traction calculations are performed in a forward manner stabilizing schemes are not needed as in the case for typical inverse problems.
We characterized the UvrABC incision of two chemically stabilized analogues (Scheme 2) of interstrand cross-links produced by oxidatively damaged DNA (Scheme 1).
We then introduce our explicit approach which is based on three main ingredients: first recast the RD discretization as a stabilized Galerkin scheme, then use a shifted time discretization in the stabilization operator, and lastly apply high order mass lumping on the Galerkin component of the discretization.
In this paper a stabilized discretization scheme for the heterogeneous and anisotropic diffusion problems is proposed on general, possibly nonconforming polygonal meshes.
