—Commercial off-the-shelf autonomous underwater vehicles (AUVs) are commonly equipped with short range radios (for high bandwidth, low-cost close range operation) and satellite modems (for low bandwidth, global operation). In a coastal observatory it should thus be possible to exploit an AUVs' proximity to the coast to use the short range radios when(More)
Trace elements (Fe, Mn, Al, Zn, Cr, Cu, Ni, Pb, Cd, Hg, and As) and stable isotope ratios (delta(13)C and delta(15)N) were analyzed in sediments, invertebrates, and fishes from a tropical coastal lagoon influenced by iron ore mining and processing activities to assess the differences in trace element accumulation patterns among species and to investigate(More)
— Radio communications between an Autonomous Underwater Vehicle at sea and shore-based base-stations faces considerable challenges particularly if the antenna on the vehicle does not rise high enough above the water surface. At distances comparable to the maximum line-of-sight distance to a base-station at a given height, situations may occur where the(More)
Massive Multiple-input Multiple-output (MIMO) systems offer exciting opportunities due to their high spectral efficien-cies capabilities. On the other hand, one major issue in these scenarios is the high-complexity detectors of such systems. In this work, we present a low-complexity, near maximum-likelihood (ML) performance achieving detector for the(More)
