The increasing availability of ubiquitous, small, low-cost devices using wireless communications to build wireless sensor networks calls for autonomous solutions and algorithms capable of calculating the location where the information is gathered, processed, used. The requirements are particularly strict when sensor nodes are mobile; in fact, mobile(More)
—Cooperative positioning algorithms have been recently introduced to overcome the limitations of traditional methods, relying on GNSS or other terrestrial infrastructure. In particular, SPAWN (Sum-Product Algorithm over a Wireless Network) was shown to provide accurate position estimate even in challenged indoor environments, thanks to exchange of local(More)
DNA sequences can be analyzed by spectral techniques, looking for hidden periodicities. Anyway, mapping between nucleotide bases and numeric values has a strong impact on the DNA spectrum. The Minimum Entropy Mapping algorithm introduced the concept of adaptive mapping: the association between bases and numbers is not fixed, but is chosen to minimize a cost(More)
