—The present work establishes that the usual method of remote measurement of vegetation reflectance can also detect steady-state solar-induced fluorescence of vegetation. It identifies the hyperspectral signature of chlorophyll fluorescence as a small spike on the reflectance spectral curve of vegetation at the oxygen absorption (O 2 –A) band around 760 nm.(More)
In this article, we discuss the space-time of a global monopole field as a candidate for galactic dark matter in the context of scalar tensor theory. It is believed that our Universe in the past was denser and hotter. So the early stage of the Universe was in a systematic phase and there were no topological defects. As the Universe expands, it cools down(More)
A methodology is proposed for extracting information on land cover based on hyperspectral reflectance data derived from satellite image, without supervising with ground truth. The reflectance percentage, being a characteristic feature of the ground object acts as an indirect guidance to the classification and hence the method is named semi-supervised(More)
