In Online Social Networks (OSNs), participants can conduct rich activities, where trust is one of the most important factors for their decision making. This necessitates the evaluation of the trustworthiness between two unknown participants along the social trust paths between them based on the trust transitivity properties (i.e., if A trustsB andB trusts C, then A can trust C to some extent). ...

One of the ASR applications is the generation of transcripts to facilitate searching through multi-media collections containing spoken data. Especially in the broadcast news domain ASR systems have been successfully deployed to index large collections of news. First of all because retrieval performed on ASR generated transcripts with an word-error rate (WER) under 50% gives resonable results [1...

We present off-nuclear spectra of 3 radio loud QSO’s, 3C249.1, 3C273 and 3C323.1., taken with the echellette spectrograph and imager (ESI) at Keck observatory. From these spectra we have extracted the spatial profile along the slit of the [OIII], λ = 5007 line. Fitted Gaussian distributions to each of these profiles show emission-line gas out to several tens of kiloparsecs from the galaxy nucle...

Seinosuke Toda introduced the class Mid P of functions that yield the middle element in the set of output values over all paths of nondeterministic polynomial time Turing machines. We deene two related classes: Med P consists of those functions that yield the middle element in the ordered sequence of output values of nondeterministic polynomial time Turing machines (i.e. we take into account th...

This paper deals with the problem of entry deterrence in two different ways. First, we analyze conditions under which entry prevention is the best strategy for an incumbent firm, and second, we link entry prevention with another important field of industrial organization, the analysis of reasonable conjectures. That entry prevention may be of interest for incumbent firms has been studied by Osb...

We investigate the possibility of using accelarator beam particles to collide with the ambient neutralino dark matter particles in cosmic rays as a way to search for the cold dark matter. We study in detail its inelastic and elastic scattering with the projectile particles at electron-positron colliders and discuss the possible experimental signals and the relevent background. There is strong e...

in this study which was carried out in 1974 in the province of isphahan a total of 23,273 individuals in the cities, and 18,671 individuals in the villages of the same area were studied. results show that the median age in rural area is 16 and in urban area is 18 years. the birth rate in rural is 27.7 per thousand were as the same rate in urban area is 40.2 per thousand. similarly the general f...
