The olefin moiety presents in styrylsulfonylmethyl-1,2,4-triazolylamine (1) was exploited to build up five-member heterocycle-pyrazoles. series of novel pyrazolyl-1,2,4-triazole amine derivatives (2-3) have been synthesized. All the entitles compounds were characterized by 1H and 13C NMR spectra.

Multispectral and hyperspectral feature spaces are useful for a variety of remote sensing applications ranging from spectral mixture modeling to discrete thematic classification. In many these applications, models used project the higher dimensional continuum reflectances (or radiances) onto lower mappings image target’s physical properties or categorical composition. such cases, characterizati...
