Untouched Antarctica: mapping a finite and diminishing environmental resource

A new total variation diminishing implicit nonstandard finite difference scheme for conservation laws

In this paper, a new implicit nonstandard finite difference scheme for conservation laws, which preserving the property of TVD (total variation diminishing) of the solution, is proposed. This scheme is derived by using nonlocal approximation for nonlinear terms of partial differential equation. Schemes preserving the essential physical property of TVD are of great importance in practice. Such s...

Calving Fronts of Antarctica: Mapping and Classification

Antarctica is surrounded by a variety of large, medium and small sized ice shelves, glacier tongues and coastal areas without offshore floating ice masses. We used the mosaic of the Radarsat-1 Antarctica Mapping Project (RAMP) Antarctic Mapping Mission 1 (AMM) to classify the coastline of Antarctica in terms of surface structure patterns close to the calving front. With the aid of an automated ...

Transformational Change in Environmental and Natural Resource Management

It is widely agreed the Anthropocene has seen an unprecedented decline in the natural resources conditions that have underpinned the economic growth of the last few hundred years. As communities, we have not responded to Boulding’s vision of ‘the coming space ship earth’ although not for want of much official and private effort. As ‘wicked problems’ the impacts have been often ignored or off lo...

Distributed multiagent resource allocation in diminishing marginal return domains

We consider a multiagent resource allocation domain where the marginal production of each resource is diminishing. A set of identical, self-interested agents requires access to sharable resources in the domain. We present a distributed and random allocation procedure, and demonstrate that the allocation converges to the optimal in terms of utilitarian social welfare. The procedure is based on d...
