Streetonomics: Quantifying culture using street names
Quantifying a society's value system is important because it suggests what
people deeply care about -- it reflects who they actually are and, more
importantly, who they will like to be. This cultural quantification has been
typically done by studying literary production. However, a society's value
system might well be implicitly quantified based on the decisions that people
took in the past and that were mediated by what they care about. It turns out
that one class of these decisions is visible in ordinary settings: it is
visible in street names. We studied the names of 4,932 honorific streets in the
cities of Paris, Vienna, London and New York. We chose these four cities
because they were important centers of cultural influence for the Western world
in the 20th century. We found that street names greatly reflect the extent to
which a society is gender biased, which professions are considered elite ones,
and the extent to which a city is influenced by the rest of the world. This way
of quantifying a society's value system promises to inform new methodologies in
Digital Humanities; makes it possible for municipalities to reflect on their
past to inform their future; and informs the design of everyday's educational
tools that promote historical awareness in a playful way.Comment: 17 pages, 6 figures, 2 table
Mobility-Aware, Correlation-Based Node Grouping and Selection for Cooperative Spectrum Sensing, Journal of Telecommunications and Information Technology, 2014, nr 2
Cooperative spectrum sensing has been proposed as a solution to increase the sensing function accuracy in cognitive radio networks, but the research has, so far, mainly focused on static scenarios, all but neglecting the impact of mobility on spectrum sensing. In this work a novel cooperative spectrum sensing scheme for mobile cognitive networks, based on a correlation-based, mobility-aware node selection algorithm is proposed. Correlation among sensing decisions is used to divide nodes into groups, and mobility is taken into account in the group leaders selection by means of a node selection metric that considers both sensing performance and mobility. Performance of the proposed algorithm is evaluated by computer simulations taking into account mobility and a detailed modeling of temporal and spatial correlation of fading and shadowing components in the channel path loss, going way beyond the performance evaluation carried out in previous works on correlation-based cooperative sensing schemes. Simulation results highlight that the proposed metric leads to a signi cant increase of the update period required to maintain acceptable sensing performance, and correspondingly to a strong reduction in the overhead caused by the grouping and node selection procedure

D13.3 Overall assessment of selected techniques on energy- and bandwidth-efficient communications
Deliverable D13.3 del projecte europeu NEWCOM#The report presents the outcome of the Joint Research Activities (JRA) of WP1.3 in the last year of the Newcom# project. The activities focus on the investigation of bandwidth and energy efficient techniques for current and emerging wireless systems. The JRAs are categorized in three Tasks: (i) the first deals with techniques for power efficiency and minimization at the transceiver and network level; (ii) the second deals with the handling of interference by appropriate low interference transmission techniques; (iii) the third is concentrated on Radio Resource Management (RRM) and Interference Management (IM) in selected scenarios, including HetNets and multi-tier networks.Peer ReviewedPostprint (published version
