Boundary element method for resonances in dielectric microcavities

A boundary element method based on a Green's function technique is introduced to compute resonances with intermediate lifetimes in quasi-two-dimensional dielectric cavities. It can be applied to single or several optical resonators of arbitrary shape, including corners, for both TM and TE polarization. For cavities with symmetries a symmetry reduction is described. The existence of spurious solutions is discussed. The efficiency of the method is demonstrated by calculating resonances in two coupled hexagonal cavities.Comment: 9 pages, 7 figures (quality reduced

Multithreaded enhancements of the Dijkstra algorithm for route optimization in urban networks

In this paper, we present a case study, showing step by step, how to speed up Dijkstra’s method by parallelizing its computation and using different data structures. We compare basic algorithm with its bidirectional version and investigate two-and-multi-thread implementations based on Fibonacci heaps and regular priority queues. Experimental results obtained for artificially generated graphs as well as real-world road network data are presented and described
