Confronted with a looming crisis of ecological deprivation and global resource depletion, the political response of most liberal regimes has been a complacent wait-and-see attitude, at best combined with piecemeal environmental reforms and moral support for international initiatives such as the Kyoto Treaty. Meanwhile, the theoretical discourse on sustainability seems to be oscillating between the

When concatenated coding schemes operate near channel capacity their component encoders may operate above capacity. The decoding bit-error performance of binary convolutional codes near and above capacity is investigated

Solid oxide fuel cells (SOFCs) are promising candidates for future energy systems due to their ability to use renewable fuels and that they are energy efficient. A fully coupled two-dimensional computational fluid dynamics (CFD) model based on the finite element method (using COMSOL Multiphysics) is developed to describe an intermediate temperature SOFC single cell. Governing equations for various

ForcePAD is an intuitive tool for visualising the behavior of structures subjected to loading and boundary conditions. The design of the user interface aims to be as intuitive as a standard image processing software. Users should be able to design structures, apply and boundary conditions and visualise results without knowledge of the underlying nite element model.
