—In the past, many clustering algorithms for ad-hoc networks have been proposed. Their main objective is to solve the scalability issue of ad-hoc networks by grouping nodes into clusters. The challenge in MANETs for those clustering algorithms is to cope with the high node mobility which affects the stability of the cluster structures. Wireless mesh(More)
We present a defect-free lithography method for printing periodic features with nanoscale resolution using coherent extreme ultraviolet light. This technique is based on the self-imaging effect known as the Talbot effect, which is produced when coherent light is diffracted by a periodic mask. We present a numerical simulation and an experimental(More)
