This note presents three ways of constructing simultaneous condence intervals for linear estimates of linear functionals in inverse problems, including \Backus-Gilbert" estimates. Simultaneous con dence intervals are needed to compare estimates, for example, to nd spatial variations in a distributed parameter. The notion of simultaneous con dence intervals is introduced using coin tossing as an...

bstract. We propose a novel unsupervised multiresolution adapive and progressive gradient-based color-image segmentation algoithm (MAPGSEG) that takes advantage of gradient information in n adaptive and progressive framework. The proposed methodolgy is initiated with a dyadic wavelet decomposition scheme of an rbitrary input image accompanied by a vector gradient calculation f its color-convert...

—Phylogenetic analyses of large data sets pose special challenges, including the apparent tendency for the bootstrap support for a clade to decline with increased taxon sampling of that clade. We document this decline in data setswith increasing numbers of taxa in Astragalus, the most species-rich angiospermgenus. Support for one subclade, Neo-Astragalus, declinedmonotonicallywith increased sam...

in this paper, the notions of $(t,s)$-composition matrix and$(t,s)$-interval-valued intuitionistic fuzzy equivalence matrix areintroduced where $(t,s)$ is a dual pair of triangular module. theyare the generalization of composition matrix and interval-valuedintuitionistic fuzzy equivalence matrix. furthermore, theirproperties and characterizations are presented. then a new methodbased on $tilde{...

background: prolonged qt interval may lead to serious arrhythmias and ventricular fibrillation, hence prevention of the qt-interval prolongation is crucial for physicians. the aim of this study was to assess the influence of intravenous lidocaine on the qtc interval resulting from spinal anesthesia with bupivacaine. methods: in a randomized double blind trial, fifty male patients with mean age ...
