(Springer, 2017)We present the first algorithms that perform the LZ78 compression of a text of length n over alphabet [1..σ], whose output is z integers, using only O(z lg σ) bits of main memory. The algorithms read the input text from ...
-
(Springer, 2017)The Block Tree is a recently proposed data structure that reaches compression close to Lempel-Ziv while supporting efficient direct access to text substrings. In this paper we show how a self-index can be built on top of ...
-
(Springer, 2017)It is an open problem whether the 3-coloring problem can be solved in polynomial time in the class of graphs that do not contain an induced path on t vertices, for fixed t. We propose an algorithm that, given a 3-colorable ...
-
(CEUR-WS, 2017)IMGpedia is a linked dataset that provides a public SPARQL endpoint where users can answer queries that combine the visual similarity of images from Wikimedia Commons and semantic information from existing knowledge-bases. ...
-
(Oxford University Press, 2017)The Puyehue-Cordon Caulle Volcanic Complex (PCCVC) is one of the best examples of tectonic control on volcanism at the Southern Volcanic Zone of the Andes (southern Chile). The PCCVC comprises several volcanic centres that ...
-
(Springer, 2017)In this paper, decentralized reinforcement learning is applied to a control problem with a multidimensional action space. We propose a decentralized reinforcement learning architecture for a mobile robot, where the individual ...
-
(Springer, 2017)Having a good estimation of the robot-players positions is becoming imperative to accomplish high level tasks in any RoboCup League. Classical approaches use a vector representation of the robot positions and Bayesian ...
-
(IOP Publishing, 2017)We present final natural-system optical (ugriBV) and near-infrared (YJH) photometry of 134 supernovae (SNe) with probable white dwarf progenitors that were observed in 2004-2009 as part of the first stage of the Carnegie ...
-
(Elsevier, 2017)We demonstrate that the anodization of copper in alkaline water/ethylene glycol media containing fluoride ions generates nanostructured copper oxide films. By modifying the anodization conditions (fluoride and OH– ...
-
(Springer, 2017)The proliferation of social media tools for facilitating interpersonal communication has inadvertently modified the ways in which intergenerational exchanges are supported. However, such technology has generally not ...
-
(Springer, 2017)Virtual museums have been very popular since the early days of the World Wide Web and many scientific works have been published on this topic. Although the rich variety of possibilities for supporting collaboration among ...
-
(Springer, 2017)Digital games have become increasingly popular for both entertainment and education purposes. However, making these games universal and accessible poses a challenge for interface designers and game developers, since they ...
-
(Springer, 2017)There are many representations of planar graphs but few are as elegant as Turán’s (1984): it is simple and practical, uses only four bits per edge, can handle multi-edges and can store any specified embedding. Its main ...
-
(Springer, 2017)Teaching and learning in most current university lectures has remained unchanged for centuries and nowadays, large lecture classes are a fact at universities. Technologies such as Classroom Response Systems have been ...
-
(Wiley, 2017)This paper proposes a novel simulator of energy consumption patterns that allows designing demand side management(DSM) strategies without economic incentives. The simulator emulates consumers’patterns with and without ...
-
(Springer, 2017)An unsupported microspherical ReS2 catalyst, consisting in self-assembled nano-layers, was evaluated in the hydrodesulfurization (HDS) of 3-methylthiophene showing an excellent catalytic activity. The samples were ...
-
Adjustment of discrete load changes in feeder databases for improving medium-term demand forecasting (Institution of Engineering and Technology, 2017)A discrete load change (DLC) event may be described as an abrupt change in feeder demand. These events are due to network reconfigurations, or the connection/disconnection of large consumers to the grid. This phenomenon ...
-
(Pontificia Universidad Catolica de Chile, Escuela de Construccion Civil, 2017)One of the problem of geotechnical engineering is the analysis of the retaining walls stability, where are several uncertainty sources. Some of these uncertainties relate to the inherent variability of fill soil, retained ...
-
(IEEE, 2017)Clustering is one of the main data mining tasks with many proven techniques and successful real-world applications. However, in changing environments, the existing systems need to be regularly updated in order to describe ...
-
(Springer, 2017)The Linked Data Fragment (LDF) framework has been proposed as auniform view to explore the trade-offs of consuming Linked Data when serversprovide (possibly many) different interfaces to access their data. Every such ...
