Clusters in protein interaction networks can potentially help identify functional relationships among proteins. The clustering problem can be modeled as a graph cut problem. Given an edge weighted graph the problem is to partition the vertices of the graph into k partitions of prescribed sizes such that the total weight of the edges within partitions are maximized. This problem is NP-complete for...
This paper addresses the problem of frequency domain packet scheduling (FDPS) incorporating spatial division multiplexing (SDM) multiple input multiple output (MIMO) techniques on the 3GPP long term evolution (LTE) downlink. We impose the LTE MIMO constraint of selecting only one MIMO mode (spatial multiplexing or transmit diversity) per user per transmission time interval (TTI). First, we address...
In this paper, an exact analytical model for computation of burst length distribution under time-correlated input sources, at the output of an edge optical burst switching node, has been developed. Approximation techniques, to reduce time complexity of the model, have also been suggested. Effects of time correlation is successfully captured and it is found that for constant load, the variance of burst...
