Requirement on multi-point data distribution in IP networks assumes some distribution service, be it implemented as a part of network native services (IP multicast) or user-empowered solution (data reflectors). In our previous work, we have introduced user-empowered distribution networks based on Active Elements (AE) [1], which scale well in terms of number of clients connected. It is however n...

a compact formulation of the set of tours neither in a graph nor its complement is presented and illustrates a general methodology proposed for constructing polyhedral models of decision problems based upon permutations, projection and lifting techniques. directed hamilton tours on n vertex graphs are interpreted as (n-1)- permutations. sets of extrema of birkhoff polyhedra are mapped to tours ...

This work focuses on an experimental and numerical investigation into monitoring damage in a cube-shaped concrete specimen under compression. Experimental uses acoustic emission (AE) signals acquired by two independent measurement apparatuses, the same process is numerically simulated with lattice discrete element method (LDEM). The results from experiment simulation are then compared terms of ...
