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 ...
GraCT: A Grammar-based Compressed Index for Trajectory Data
(Elsevier Ltd, 2019)
[Abstract]: We introduce a compressed data structure for the storage of free trajectories of moving objects that efficiently supports various spatio-temporal queries. Our structure, dubbed GraCT, stores the absolute positions ...
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 ...
Applicability of EU(7)-PIM criteria in cross-national studies in European countries
(2019)
[Abstract] Background: The European Union (EU)(7)-PIM (potentially inappropriate medication) list
presents the most comprehensive and up-to-date tool for evaluation of PIM prescribing in
Europe; however, several ...
New Treebank or Repurposed? On the Feasibility of Cross-Lingual Parsing of Romance Languages with Universal Dependencies
(Cambridge University Press, 2018-01)
[Abstract] This paper addresses the feasibility of cross-lingual parsing with Universal Dependencies (UD) between Romance languages, analyzing its performance when compared to the use of manually annotated resources of the ...
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 ...
Spectrally undiscerned isomers might lead to erroneous determination of water exchange rates of paraCEST Eu(III) agents
(American Chemical Society, 2017-07-17)
[Abstract] We report a detailed study of the solution structure and water exchange rate of a Eu(III) complex with the cyclen-based ligand L1, containing (S)-2-(2-acetamido)-3-(4 (trifluoromethyl)phenyl)propanoate pendant ...
