The Das-Moser commutator closure for filtering through a boundary is well-posed
When filtering through a wall with constant averaging radius, in addition to the subfilter scale stresses, a non-closed commutator term arises. We consider a proposal of Das and ...

Reaching consensus in asynchronous WSNs: Algebraic approach
Many models of wireless sensor networks (WSNs) assume a perfect synchronization along the graph of such network as a simplifying assumption. In our contribution we base our invest...
