Estudio multitemporal de imágenes usando la transformación de componentes principales
, 1993 [EN]The principal components transformation in used to highlight areas that show a change in time, normally associated with fire damage and vegetation regrowth. These variations are enhanced in the high order components, following previous studies. The components are classified by unsupervised techniques to yield thematic maps on which dynamic cover ...

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films
Advanced Functional Materials, EarlyView.Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...
