(Elsevier, 2017)A connected graph G=(V,E) with m edges is called universal antimagic if for each set B of m positive integers there is an bijective function f:E→B such that the function f˜:V→N defined at each vertex v as the sum of all ...

(Elsevier, 2017)Microalgae culture fed with ammonium may face the presence of nitrifying bacteria. The aim of this paper is to propose and analyze a nonlinear system which represents the dynamics of these two species (microalgae and ...

(Association for Computing Machinery, 2017)Today online social networks seem to be good tools to quicklymonitor what is going on with the population, since they provideenvironments where users can freely share large amounts of infor-mation related to their own ...

(Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2017)Karp et al. (1988) described Deferred Data Structures for Multisets as “lazy” data structureswhich partially sort data to support online rank and select queries, with the minimum amount ofwork in the worst case over instances ...
-
(IEEE, 2017)For the last ten years we have been teaching acapstone course for fifth year students of the Computer ScienceDepartment of the Universidad de Chile. Five year ago weredesigned the course, shifting from ...
-
(IEEE, 2017)Wireless sensor networks are pervasive systems that continuously demonstrate increase in growth by branching into diverse applications. The state of charge is an indicator that conveys the amount of energy available in ...
-
(Elsevier, 2017)Earth has been a traditional building material to construct structures in many different continents. In particular, adobe buildings are widely diffused in South America, and in Peru where form part of the cultural identity ...
-
(Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2017)The General Scheduling Problem (GSP) generalizes scheduling problems with sum of cost objectives such as weighted flow time and weighted tardiness. Given a set of jobs with processing times, release dates, and job dependent ...

(Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2017)In this paper we present distributed property-testing algorithms for graph properties in thecongestmodel, with emphasis on testing subgraph-freeness. Testing a graph propertyPmeansdistinguishing graphsG= (V,E)having ...
-
(IEEE, 2017)The ongoing implementation of a fog observatory in a coastal fog forest in northern Chile is expected to provide valuable information to improve our comprehension of these ecosystems alongside retrieving valuable data to ...
-
(Institute of Physics, 2017)We compare the structure of molecular gas at 40pc resolution to the ability of gas to form stars across the disk of the spiral galaxy M51. We break the PAWS survey into 370pc and 1.1kpc resolution elements, and within ...
-
(Elsevier, 2017)Sinter deposits are formed by precipitation of silica from hydrothermal fluids that have reached the surface environment. They are commonly found around hot springs and represent surface expressions of underlying geothermal ...
-
(Elsevier, 2017)The geomorphology of the Denton Hills provides insight into the timing and magnitude of glacial retreats in a region of Antarctica isolated from the influence of the East Antarctic ice sheet. We present 26 Beryllium-10 ...
-
(Association for Computing Machinery, 2017)Posted price mechanisms constitute a widely used way of selling items to strategic consumers. Although subop-timal, the a ractiveness of these mechanisms comes from their simplicity and easy implementation. In this pa-per, ...

Almost partitioning 2-edge-colourings of 3-uniform hypergraphs with two monochromatic tight cycles (Elsevier B.V., 2017)We show that any 2-colouring of the 3-uniform complete hypergraph Kn (3) on n vertices contains two disjoint monochromatic tight cycles of distinct colours covering all but o(n) vertices of Kn (3). The same result holds ...
-
(Elsevier, 2017)Understanding the evolution of a volcanic edifice is important in establishing its associated geological hazards. Apacheta and Aguilucho volcanoes, northern Chile, formed a volcanic complex with known fumaroles and geo-thermal ...
-
(Elsevier, 2017)The precipitation kinetics of secondary phases in a 10.5%Cr heat resistant steel, designed by the authors, was studied experimentally and theoretically. Experimental data of nucleation, growth and coarsening stages for ...
-
(Taylor and Francis, 2017)Recoverable mineral resources assessment has become a standard geostatistical application in the mining industry, with various geostatistical techniques currently available. This investigation aimed to improve the prediction ...
-
(Heldermann Verlag, 2017)Bregman distances play a key role in generalized versions of the proximal algorithm. This paper proposes a new characterization of Bregman distances in terms of their gradient and Hessian matrix. Thanks to this characterization, ...
-
(Elsevier, 2017)The Tolhuaca Volcano near Lonquimay in south-central Chile has been the subject of several studies due to its geothermal manifestations, but little is known about the stratigraphy and reservoir potential of the Cura-Mallin ...
