Transnational social mobility strategies and quality of work among latin-american women sex workers in Spain
(Universities of Surrey and Stirling, Sage Publications Ltd. and the British Sociological Association, 2016-11-30)
[Abstract] The aim of this article is to analyse the quality of work of two of the main types of female sex work in Spain (clubs and in-call flats). In order to do so I will focus on the following working dimensions: wages, ...
Navigational Rule Derivation: An algorithm to determine the effect of traffic signs on road networks
(2016-11-17)
[Abstract] In this paper we present an algorithm to build a road network map enriched with traffic rules such as one-way streets and forbidden turns, based on the interpretation of already detected and classified traffic ...
Efficient and Compact Representations of Some Non-canonical Prefix-Free Codes
(Springer, 2016-09-21)
[Abstract] For many kinds of prefix-free codes there are efficient and compact alternatives to the traditional tree-based representation. Since these put the codes into canonical form, however, they can only be used when ...
GraCT: A Grammar Based Compressed Representation of Trajectories
(Springer, 2016-09-21)
[Abstract] We present a compressed data structure to store free trajectories of moving objects (ships over the sea, for example) allowing spatio-temporal queries. Our method, GraCT, uses a k2k2 -tree to store the absolute ...
Grammar compressed sequences with rank/select support
(Elsevier BV, 2016-10-14)
[Abstract] Sequence representations supporting not only direct access to their symbols, but also rank/select operations, are a fundamental building block in many compressed data structures. Several recent applications need ...
Universal indexes for highly repetitive document collections
(Elsevier Ltd, 2016-11)
[Abstract] Indexing highly repetitive collections has become a relevant problem with the emergence of large repositories of versioned documents, among other applications. These collections may reach huge sizes, but are ...
Los primeros robots manipuladores aéreos
(Comité Español de Automática, 2016)
[Resumen] En este artículo se describen los primeros robots manipuladores aéreos dotados con brazos robóticos de seis grados de libertad y capacidades de percepción y planificación que se han desarrollado en el mundo. Estos ...
Parallel construction of wavelet trees on multicore architectures
(Springer U K, 2016-10-05)
[Abstract] The wavelet tree has become a very useful data structure to efficiently represent and query large volumes of data in many different domains, from bioinformatics to geographic information systems. One problem ...
Compact Trip Representation over Networks
(Springer, 2016-09-21)
[Abstract] We present a new Compact Trip Representation ( CTRCTR ) that allows us to manage users’ trips (moving objects) over networks. These could be public transportation networks (buses, subway, trains, and so on) where ...
Aggregated 2D range queries on clustered points
(Elsevier Ltd, 2016-09)
[Abstract] Efficient processing of aggregated range queries on two-dimensional grids is a common requirement in information retrieval and data mining systems, for example in Geographic Information Systems and OLAP cubes. ...
