Comparing freight transport strategies and measures in London and Paris

The paper compares the approach being taken to freight transport strategy and the specific policy measures being implemented in London and Paris. It highlights the serious consideration that has been given to freight transport by the Mayors of London and Paris in the last five years. These freight policy considerations are taking place against a background of growing levels of road freight activity, energy use and pollutant emissions in both cities. The key freight transport objectives being followed in London and Paris are similar and focus on improving the efficiency and reliability of freight transport while reducing the negative environmental impacts that it causes. The specific freight transport policy measures being followed show some differences in each city. However, attempts to address problems related to loading and unloading are taking place in both, albeit through different specific initiatives. These policy initiatives have important implications for companies concerned with urban logistics operations.

Quantitative evaluation of three reconfiguration strategies on FPGAs: a case study

Reconfigurable computing is becoming an important new alternative for implementing computations. Field programmable gate arrays (FPGAs) are the ideal integrated circuit technology to experiment with the potential benefits of using different strategies of circuit specialization by reconfiguration. The final form of the reconfiguration strategy is often non-trivial to determine. Consequently, in this paper, we examine strategies for reconfiguration and, based on our experience, propose general guidelines for the tradeoffs using an area-time metric called functional density. Three experiments are set up to explore different reconfiguration strategies for FPGAs applied to a systolic implementation of a scalar quantizer used as a case study. Quantitative results for each experiment are given. The regular nature of the example means that the results can be generalized to a wide class of industry-relevant problems based on arrays.
