Using data from an association of coffee cooperatives in Central America, we verify that arbitrage on this margin causes ...

At high transmission speeds, complexity of implementation for fair queuing disciplines can impose a bottleneck to the overall system performance. Available scheduling algorithms set a fixed trade off between fairness and complexity, fairer systems involving more operations per packet and vice versa. In this paper first a new fair queuing scheme is proposed, with almost the same fairness and com...

In this paper, we, therefore, investigate greening and show that it can be decomposed into two dimensions: the price of g...
