Hyperspectral imaging of speleothems
Proxy records from speleothems are used in palaeoclimatic reconstructions, as the factors controlling their growth rate, nature of their internal structure and chemical composition respond to changes in surface climate. Optical analyses of stalagmites include visual observation of stalagmite images obtained from flatbed scanners or digital cameras. Hyperspectral imaging has not been used in sta...

متن کاملSeasonality in Tourism and Forecasting Foreign Tourist Arrivals in India
In the present age of globalization, technology-revolution and sustainable development, the presence of seasonality in tourist arrivals is considered as a key policy issue that affects the global tourism industry by creating instability in the demand and revenues. The seasonal component in a time-series distorts the prediction attempts for policy-making. In this context, it is quintessential to...
متن کاملModeling and Rendering the Growth of Speleothems in Real-time
Among the many natural phenomena already studied in computer graphics research, the interior of caves remains largely unexplored. We present in this paper a plausible approach, based on Geological studies, for modeling the genesis and growth of speleothems. Speleothems are mineral depositions formed in caves, such as stalactites, stalagmites and columns. Our approach takes advantage of the new ...
متن کاملModification and preservation of environmental signals in speleothems
Speleothems are primarily studied in order to generate archives of climatic change and results have led to significant advances in identifying and dating major shifts in the climate system. However, the climatological meaning of many speleothem records cannot be interpreted unequivocally; this is particularly so for more subtle shifts and shorter time periods, but the use of multiple proxies an...
