Rotating detonation engines (RDEs) have been observed to exhibit several operating modes and instabilities under different operation conditions (reactant mixture, injection pressure, engine geometry, mass flow rate, etc.). We develop the simplest model possible describing of an RDE. This takes into account dependence properties on conditions, process, geometric constraints. Using this model, we...

This report provides an (updated) overview of Grafalgo, an opensource library of graph algorithms and the data structures used to implement them. The programs in this library were originally written to support a graduate class in advanced data structures and algorithms at Washington University. Because the code’s primary purpose was pedagogical, it was written to be as straightforward as possib...

We study the maximum flow problem in an undirected planar network with both edge and vertex capacities (EVC-network). A previous study reduces the minimum cut problem in an undirected planar EVC-network to the minimum edge-cut problem in another planar network with edge capacity only (EC-network), thus the minimum-cut or the maximum flow value can be computed in O(n log n) time. Based on this r...
