In this article, for the given wavelength division multiplexing (WDM) network, the demand traffic matrix, the old and new survivable virtual topologies which are protected by the failure-independent path-protecting p-cycles (FIPP p-cycles) protection scheme, the virtual topology transition sequence (VTTS) problem is studied. The goal of this problem is to(More)
We report the results obtained from the studies of polymer-stabilized cholesteric texture films. Two sets of samples were fabricated. The first set were fabricated by adding various ferroelectric liquid crystal (SmC*) dopant concentrations in the mixtures. The second were fabricated using a dual-frequency liquid crystal. The experimental results obtained(More)
