One of the main objectives of cognitive radar is to adapt the spectrum of transmit waveforms to certain needs, such as avoiding reserved frequency bands or narrowband interferences. Besides spectral… (More)
XML and other types of semistructured data are typically represented by a labeled directed graph. To speed up path expression queries over the graph, a variety of structural indexes have been… (More)
