Received ABSTRACT An analysis of voids using cosmological N-body simulations of cold dark matter (CDM) models is presented. It employs a robust statistics of voids, that was recently applied to discriminate between data from the Las Campanas Redshift Survey (LCRS) and different cosmological models. Here we extend the analysis to 3D and show that typical void sizes D in the simulated galaxy samp...

a method based on electrical capacitance tomography (ect) and an improved least squares support vector machine (ls-svm) is proposed for void fraction measurement of oil-gas two-phase flow. in the modeling stage, to solve the two problems in ls-svm, pruning skills are employed to make ls-svm sparse and robust; then the real-coded genetic algorithm is introduced to solve the difficult problem of ...

The objective of this article is to present a semiotic analysis of void— which in this article is the spacio-temporal empty space existing in any representation—in order to consider the representation of quality and to show how this is essential in human representation yet difficult to process computationally. First, a summary of reference to void is presented through a comparison between Weste...

We study the possible magnetization of cosmic voids by void galaxies. Recently, observations revealed isolated starforming galaxies within the voids. Furthermore, a major fraction of a voids volume is expected to be filled with magnetic fields of a minimum strength of about 10 −15 G on Mpc scales. We estimate the transport of magnetic energy by cosmic rays (CR) from the void galaxies into the v...

Dataset description vocabularies focus on provenance, versioning, licensing, and similar metadata. VoID is a notable exception, providing some expressivity for describing subsets and their contents and can, to some extent, be used for discovering relevant resources and for optimizing querying. In this paper we describe the Sevod vocabulary, an extension of VoID that provides the expressivity ne...

Detection of a large void (∼7 Mpc) is reported between the redshifts 2.16286 and 2.20748 in the Ly α forest of TOL 1038-2712. This void is centered near a foreground QSO TOL 1037-2704 which is at a distance ∼4.4 Mpc away from the void. The estimated probability for the void to occure by chance in front of the foreground QSO is few times 10 −3. Various implications of the void being produced by ...
