On the structure and arithmeticity of lattice envelopes
Article history: Received 28 November 2014 Accepted after revision 9 February 2015 Available online 25 March 2015 Presented by the Editorial Board We announce results about the structure and arithmeticity of all possible lattice embeddings of a class of countable groups that encompasses all linear groups with simple Zariski closure, all groups with non-vanishing first 2-Betti number, non-elemen...
متن کاملUncertainty envelopes
We introduce a new class of problems: computing the set of all the convex combinations of sites when their position is uncertain and depends linearly on shared parameters which vary according to a uniform distribution. The boundary of the set, called the uncertainty envelope, is useful in optimizing processes where there is uncertainty on the site positions and the objective functions. We provi...
متن کاملGreen envelopes classification: the comparative analysis of efficient factors on the thermal and energy performance of green envelopes
This paper classifies green envelopes as green roofs and green walls according to effective factors, which were derived from literature to compare the green envelopes’ thermal and energy performance in a more effective way. For this purpose, an extensive literature review was carried out by searching keywords in databases and studying related journal papers and articles. The research meth...
متن کاملStereopsis from contrast envelopes
We report two experiments concerning the site of the principal nonlinearity in second-order stereopsis. The first exploits the asymmetry in perceiving transparency with second-order stimuli found by Langley et al. (1998) (Proceedings of the Royal Society of London B, 265, 1837-1845) i.e. the product of a positive-valued contrast envelope and a mean-zero carrier grating can be seen transparently...
متن کاملRobustness envelopes of networks
We study the robustness of networks under node removal, considering random node failure, as well as targeted node attacks based on network centrality measures. Whilst both of these have been studied in the literature, existing approaches tend to study random failure in terms of average-case behavior, giving no idea of how badly network performance can degrade purely by chance. Instead of consid...
