In this paper, we suggested new algorithms to discriminate between eight analogue modulated signals (amplitude modulation (AM), frequency modulation (FM), double side band (DSB), lower side band (LSB), upper side band (USB), vestigial side band (VSB), combined (AM-FM) and carrier wave (CW)). The simulation results show that the overall recognition of the new algorithms over 97% when the signal ...

High signal-to-noise ratio spectra of Europa and Callisto’s trailing side show a 0.3% deep 5771 Å absorption band due to condensed O2 at the same wavelength as a stronger band previously identified on Ganymede. Excellent longitudinal coverage for Europa shows that unlike Ganymede, where the band is much stronger on the trailing side, Europa shows no significant longitudinal variation in the O2 ...

We have used Landsat-5 TM and Landsat-7 ETM+ images together with simultaneous ground-truth data at sample points in the Doñana marshes to predict water turbidity and depth from band reflectance using Generalized Additive Models. We have point samples for 12 different dates simultaneous with 7 Landsat-5 and 5 Landsat-7 overpasses. The best model for water turbidity in the marsh explained 38% of...

Integrated optical filters based on microring resonators play a critical role in many applications, ranging from wavelength division multiplexing and switching to channel routing. Bandwidth tunable are capable of meeting the on-demand flexible operations complex situations, due their advantages scalability, multi-functionality, being energy-saving. Recent studies have investigated how parity-ti...

The two-scale model (TSM) based on Bragg tilting is widely employed to the normalized radar cross section (NRCS) from sea surface in microwave bands. It also leads compound distribution when used represent of intensity high-resolution clutter. While TSM satisfactorily describes dynamical behavior polarized NRCS at moderate incidence angles for various states and frequencies, it fails consistent...
