[CA]En les costes valencianes, s'han arribat a visualitzar set espècies diferents d’odontocets. Destaca el dofí llistat
(Stenella coeruleoalba), el dofí comú (Delphinus delphis) i el dofí mular (Tursiops truncatus), entre ...
[EN] Accurate whistle contour extraction is crucial in many dolphin behavioural studies. Traditionally, whistle contour extraction involves a first step of finding whistle candidates by peak-level detection in the ...
[EN] Passive acoustic monitoring of underwater sounds is an emerging discipline that can be used to guarantee that anthropogenic noise meets acceptable limits, to detect the presence of cetacean species, and to ensure ...
[EN] In this paper, we present a novel and completely different approach to the problem of scattering material characterization: measuring the degree of predictability of the time series. Measuring predictability can provide ...
