The purpose of this chapter is to investigate multicommodity flow problems that appear in the network design and operation of modern broadband packet-switched networks. We present arc-node and arc-path models and analyze specialized formulations corresponding to hard to solve instances like the minimax congestion problem and the capacity assignment of data networks in the presence of failures. ...

Major disruption to a transportation network can disturb traffic flow patterns significantly. To deploy effective and efficient traffic restoration projects, a good prediction of the traffic flow pattern under network disruption is vital. Although traffic flow evolution processes have been modeled in various ways in the literature, very limited attention has been paid to the traffic flow evolut...

We present a method to find static path exclusions in a control flow graph in order to refine the WCET analysis. Using this information, some infeasible paths can be discarded during the ILP-based longest path analysis which helps to improve precision. The new analysis works at the assembly level and uses the Omega library to evaluate Presburger formulas.

Industrial trends are presenting major challenges and opportunities for research on two-phase flows in microchannels. Semiconductor companies are developing 3D circuits for which multilevel microfluidic cooling is important. Gas delivery microchannels are promising for PEM fuel cells in portable electronics. However, data and modeling are needed for flow regime stability, liquid entrainment/clo...
