(Society for Industrial and Applied Mathematics, 2017)LetDbe a collection ofDdocuments, which are strings over an alphabet of sizeσ,of total lengthn. We describe a data structure that uses linear space and reportskmost relevantdocuments that contain a query patternP, which ...
-
(Institute of Physics Publishing, 2017)The coming era of large photometric wide-field surveys will increase the detection rate of supernovae by orders of magnitude. Such numbers will restrict spectroscopic follow-up in the vast majority of cases, and hence new ...
-
(Elsevier, 2017)In this study, we examine the fracture network of the Tolhuaca geothermal system located in the Southern Andean volcanic zone that may have acted as a pathway for migration and ascent of deepseated fluids under the ...
-
(Wiley, 2017)The strain smoothing technique over higher order elements and arbitrary polytopes yields less accurate solutions than other techniques such as the conventional polygonal finite element method. In this work, we propose a ...
-
(IEEE, 2017)Inrobotic mapping and simultaneous localization and mapping, the ability to assess the quality of estimated maps is crucial. While concepts exist for quantifying the error in the estimated trajectory of a robot, or a ...
-
(Institute of Physics Publishing, 2017)Using cosmological hydrodynamical simulations, we study the effect of supernova (SN) and active galactic nucleus (AGN) feedback on the mass transport (MT) of gas onto galactic nuclei and the black hole (BH) growth down to ...
-
(IOP Publishing, 2017)We present new ALMA band-7 data for a sample of six luminous quasars at z similar or equal to 4.8, powered by fast-growing supermassive black holes (SMBHs) with rather uniform properties: the typical accretion rates and ...
-
(IOP Publishing, 2017)Chemical abundances of eight O-and B-type stars are determined from high-resolution spectra obtained with the MIKE instrument on the Magellan. 6.5 m Clay telescope. The sample is selected from 42 candidates for membership ...
-
(Elsevier, 2017)Today we have the opportunity without precedents to analyze human land use or mobility behavior in a city, country or even the globe. Some studies have analyzed existing data generated daily by mobile networks, mostly using ...
-
(Academic Press- Elsevier, 2017)We show that for any 2-local colouring of the edges of the balanced complete bipartite graph Kn,n, its vertices can be covered with at most 3 disjoint monochromatic paths. And, we can cover almost all vertices of any ...
-
(Elsevier, 2017)First, we estimate the connectivity properties of a predefined (fixed node locations) spatial network which optimizes a connectivity functional that balances construction and transportation costs. In this case we obtain a ...
-
(Elsevier, 2017)The q-Weibull model is based on the Tsallis non-extensive entropy [22] and is able to model various behaviors of the hazard rate function, including bathtub curves, by using a single set of parameters. Despite its flexibility, ...
-
(Elsevier, 2017)Typically, development of robot behavior entails writing the code, deploying it on a simulator or robot and running it in a test setting. If this feedback reveals errors, the programmer mentally needs to map the error in ...
-
(Elsevier, 2017)This study assesses the environmental impact and the potential valorization of metal-sludge waste generated by the active neutralization of extremely metal-polluted acid mine drainage (AMD). To this end, two regulated ...
-
(Elsevier, 2017)This paper examines the determinants of perceived and actual knowledge of commission paid by contributors in the Chilean pension funds industry. Results show that price consciousness and brand credibility are positively ...
-
(Taylor and Francis, 2017)A methodology is presented for deciding the location of a third ore crusher to be installed at Chile’s Chuquicamata copper mine. The proposed approach determines which location alternative exhibits the minimum capital and ...
-
(Elsevier, 2017)The method for the deconvolution of overlapping DSC peaks here proposed has been used by the first time for the quantitative determination of the enthalpies associated to the phase transitions undergone during the aging ...
-
(Elsevier, 2017)This paper presents a novel prognostic method that allows a proper characterization of the uncertainty associated with the evolution in time of nonlinear dynamical systems. The method assumes a state-space representation ...
-
An entropy-based technique for classifying bacterial chromosomes according to synonymous codon usage (Springer, 2017)We present a framework based on information theoretic concepts and the Dirichlet distribution for classifying chromosomes based on the degree to which they use synonymous codons uniformly or preferentially, that is, whether ...
-
(Elsevier, 2017)tThis study presents a novel load estimation method for isolated communities that do not receive energyor only receive it for a limited time each day. These profiles have been used to determine the installedcapacity of ...
