Average Spectra and Minimum Distances of Low-Density Parity-Check Codes over Abelian Groups
Ensembles of regular low-density parity-check codes over any finite Abelian group G are studied. The nonzero entries of the parity matrix are randomly chosen, independently and uni...

Synthesis of Petri nets from infinite partial languages
In this paper we present an algorithm to synthesize a finite unlabeled place/transition Petri net (p/t-net) from a possibly infinite partial language, which is given by a term ove...

Security for Wiretap Networks via Rank-Metric Codes
The problem of securing a network coding communication system against a wiretapper adversary is considered. The network implements linear network coding to deliver n packets from s...
