Many problems with today's Internet routing infrastructure--slow BGP convergence times exacerbated by timer-based route scanners, the difficulty of evaluating new protocols--are not architectural or protocol problems, but software problems. Router software designers have tackled scaling challenges above all, treating extensibility and latency concerns as(More)
This paper describes an implementation of the class based queueing (CBQ) mechanisms proposed by Sally Floyd and Van Jacobson 1] 2] to provide real time policies for packet forwarding. CBQ allows the traac ows sharing a data link to be guaranteed a share of the bandwidth when the link is congested, yet allows exible sharing of the unused bandwidth when the(More)
A cluster obtained in high yield from the reduction of a silver-thiolate precursor, Ag-SCH(2)CH(2)Ph, exhibited a single sharp peak near 25 kDa in the matrix-assisted laser desorption mass spectrum (MALDI MS) and a well-defined metal core of ~2 nm measured with transmission electron microscopy (TEM). The cluster yields a single fraction in high-performance(More)
In this paper, a novel strategy based on the notion of threshold is proposed to accomplish segmentation of objects and background in a scene. Optimal threshold for two class and three classes problems are determined from the histogram of featured pixel values as opposed to the original normalized histogram. Genetic algorithm (GA) and Parallel Genetic(More)
—A Parallel Genetic Algorithm (PGA) based scheme for detection of cracks in images is proposed. The proposed segmentation scheme is a feature based one and the optimum threshold is determined from the the feature histogram. Parallel Genetic Algorithm (PGA) based clustering is proposed to detect two peaks and thereafter the optimal threshold is determined by(More)
