Most modern buildings incorporate a façade system to conform to green building regulations. Several common facade systems utilize composite panels made of combustible materials and can significantly enhance the fire risk, as shown by many recent building fires. This study presents the development of a full-scale research facility at IIT Gandhinagar to better understand the behaviour of real fires involving façade systems. Such a facility will facilitate scientific studies pertaining to façade fires and help in improving fire safety of such buildings.Keywords

Crop health monitoring and assessment have become more successful with the advent of remote sensing technology in agriculture. Using this technology, retrieving information about crop biophysical parameters on a non-destructive basis at spatial and temporal scales has been made possible. Several drone-derived spectral vegetation indices (VIs) have assessed crop growth status in a larger farming area. In this study, we generated VI maps for a cotton field area in the Tamil Nadu Agricultural University, Coimbatore, India. The ground-truth chlorophyll data (SPAD-502 Minolta meter) were collected from the field on the same day of drone image acquisition. Pearson correlation analysis and regression analysis were done for validation and accuracy of the ground-truth chlorophyll data and VIs. The study reveals that obtaining near real-time chlorophyll content using high spatial resolution drone images is quick and reliableKeywords
