Measurements taken downstream of freeway/on-ramp merges have verified that discharge flow diminishes when a merge becomes an active bottleneck. We show that metering the on-ramp can recover the higher discharge flow and thereby increase merge capacity. Detailed observations collected using video revealed that the outflow drop following activation was triggered by a queue that formed near the me...

We present a comparative study of implementations of the following sorting algorithms on the Parsytec SC320 reconfigurable, asynchronous, massively parallel MIMD machine: Bitonic Sort, Odd-Even Merge Sort, Odd-Even Merge Sort with guarded split&merge, and two variants of Samplesort. The experiments are performed on 2up to 5-dimensional wrapped butterfly networks with 8 up to 160 processors. We ...

Modularity is a popular measure for the quality of a cluster partition. Primarily, its popularity originates from its suitability for community identification through maximization. A lot of algorithms to maximize modularity have been proposed in recent years. Especially agglomerative hierarchical algorithms showed to be fast and find clusterings with high modularity. In this paper we present se...
