Many partitioning methods may be used to partition a network into smaller clusters while minimizing the number of cuts needed. However, other considerations must also be taken into account when a network represents a real system such as a power grid. In this paper we use a simulated annealing Monte Carlo (MC) method to optimize initial clusters on the(More)
In Nature, the primary goal of any network is to survive. This is less obvious for engineering networks (electric power, gas, water, transportation systems etc.) that are expected to operate under normal conditions most of time. As a result, the ability of a network to withstand massive sudden damage caused by adverse events (or survivability) has not been(More)
The Reynolds-stress transport equation (RSTE) includes the velocity/pressure-gradient correlation < p,jui >. Following Rotta (1951), it is common practice to split this correlation into two parts: the pressure-strain correlation < pui,j > and the pressure-diffusion part < pui >,j . This approach has advantages if one simulates homogeneous turbulence with a(More)
Engineering networks fall into the category of large-scale networks with heterogeneous nodes such as sources and sinks. The survivability analysis of such networks requires the analysis of the connectivity of the network components for every possible combination of faults to determine a network response to each combination of faults. From the computational(More)
The paper presents an approach based on Dempster-Shafer theory of evidence to quantify uncertainty in flight plan trajectories. The approach is developed for 4D aircraft trajectories. However, as the full data set (latitude, longitude, altitude vs. time) for flight plan trajectories is not publicly available, only uncertainty in the horizontal projection(More)
