Future developments in AI and robotics, brain interfaces, the Internet and virtual and augmented reality, will make possible new types of integration of humans and machines which will change how we think, learn and live. This paper uses a story about a future scenario involving systems of this kind to respond to crises and disasters to explore the possibilities of collective intelligence and co...

Shape indices have been in use for several decades to describe the characteristics and hydrological properties of drainage basins. Due to the fractal behaviour of the basin boundary, perimeter-based shape indices depend on the scale at which they are determined. Therefore, these indices cannot objectively compare drainage basins across a range of scales and basin sizes. This paper presents an o...
