Spatial evolutionary spectrum for DOA estimation and blind signal separation

IEEE Transactions on Signal Processing, 2000
We combine the concepts of evolutionary spectrum and array processing. We present a cross-power stationary periodogram for both direction-of-arrival (DOA) estimation and blind separation of nonstationary signals. We model the nonstationary signals received by each array sensor as a sum of complex sinusoids with time-varying amplitudes. These magnitudes

Evolutionary Model for Synthetic Spectrum Compatible Accelerograms

2016
This paper proposes a numerical procedure for the generation of sets of synthetic acceleration time histories that result compatible with an assigned target design spectrum. The proposed formulation is able to take into account both the energy distribution in time and the contemporary variability of the frequency content.

The multidimensional spectrum of eco‐evolutionary relationships between sharks and remoras

Journal of Fish Biology
AbstractRemoras are a highly specialised group of fishes known to associate with a range of marine megafauna, including elasmobranchs, cetaceans and marine reptiles. Remoras appear to benefit from these interspecific interactions through consumption of host dermal parasites or reduced cost of transport.
