Reliable water supply from the Ganges and Brahmaputra is of critical importance to the sustainability of the agricultural societies of India and Bangladesh. But, the flow in both basins is highly variable on timescales ranging from days to years, creating challenges for the optimization of agricultural practices, water resource management and disaster(More)
The proliferation of mobile smart devices has led to a rapid increase of location-based services, many of which are amassing large datasets of user trajectory information. Unfortunately, current trajectory information is not yet sufficiently rich to support classification of user transportation modes. In this paper, we propose a method that employs both the(More)
M any of the largest rivers on the planet emanate from the Tibetan Plateau and the Himalayas (Fig. 1a), fed by glacial and snow melting and monsoon rainfall. Nearly 25% of the global population reside in the vast agrarian societies in the each of which is subject to periods of widespread and long-lived flooding. Flooding remains the greatest cause of death(More)
Following the popularity of smart phones and the development of mobile Internet, the demands for accurate indoor positioning have grown rapidly in recent years. Previous indoor positioning methods focused on plane locations on a floor and did not provide accurate floor positioning. In this paper, we propose a method that uses multiple barometers as(More)
The uncertainty associated with predicting extreme weather events has serious implications for the developing world, owing to the greater societal vulnerability to such events. Continual exposure to unanticipated extreme events is a contributing factor for the descent into perpetual and structural rural poverty. We provide two examples of how probabilistic(More)
