Default TVD/NVD in unstructured grids

I have been looking through the literature on ways to extend the TVD or NV (Normalized Variable) formulation of High Resolution schemes to unstructured grids. Concerning the NV formulation work at Imperial College describe one way of using HR scheme for cell centered unstructured grids, but their method is not applicable to cell vertex based grids Concerning the TVD the definition of sweby's 'r' is not clear for unstructured grid

if you have any clarification concerning these issues, I will be very glad to discuss them with you

thanks in advance
