Biogeography based Satellite Image Classification
TL;DR: Modifications have been proposed to the original BBO algorithm and the modified algorithm is used to classify the satellite image of a given region and the results indicate that highly accurate land cover features can be extracted effectively when the proposed algorithms are used.
Journal ArticleDOI
Zircon to monazite phase transition in CeVO4: X-ray diffraction and Raman-scattering measurements
V. K. Panchal,S. López-Moreno,David Santamaría-Pérez,Daniel Errandonea,Francisco Javier Manjón,Plácida Rodríguez-Hernández,Alfonso Muñoz,Srungarpu N. Achary,Avesh K. Tyagi +8 more
TL;DR: In this article, a pressure-induced irreversible phase transition from the zircon to the monazite structure was observed and diffraction peaks and Raman-active modes of the monzite phase were measured.
Journal ArticleDOI
High-pressure study of ScVO 4 by Raman scattering and ab initio calculations
V. K. Panchal,Francisco Javier Manjón,Daniel Errandonea,Plácida Rodríguez-Hernández,Javier López-Solano,Alfonso Muñoz,Srungarpu N. Achary,A. K. Tyagi +7 more
TL;DR: In this paper, the authors report results of experimental and theoretical lattice-dynamics studies on scandium orthovanadate up to 35 GPa, where the onset of an irreversible zircon-to-scheelite phase transition is detected.
