    • Da Silva, Bruno Fontana; Azurdia Meza, César; Silva, Danilo; Uchôa-Filho, Bartolomeu F. (IEEE, 2017)
      In this paper, we consider the deployment of multiple antennas as a way to exploit spatial diversity in the uplink of multiple access systems that adopt low-density spreading (LDS) with orthogonal frequency-division ...
    • Maleki, Mohammad; Emery, Xavier; Mery, Nadia (MDPI AG, 2017)
      Geostatistics offers a set of methods for modeling, predicting, or simulating geological domains in space. In addition of being an input of some of these methods, indicator direct and cross-variograms convey valuable ...

      Single-layer, ultrasmall ReS2 nanoplates embedded in amorphous carbon were synthesized from a hydrothermal treatment involving ammonium perrhenate, thiourea, tetraoctylammonium bromide, and further annealing. The rhenium ...
    • Munro, J. Ian; Navarro, Gonzalo; Nekrich, Yakov (Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2017)
      We introduce a compressed suffix array representation that, on a textTof lengthnover analphabet of sizeσ, can be built inO(n)deterministic time, withinO(nlogσ)bits of workingspace, and counts the number of occurrences of ...
    • Araya Hernández, Lerko; Osses Alvarado, Axel; Silva Sánchez, Jorge; Tobar Henríquez, Felipe Arturo (IEEE, 2017)
      The interferometry problem addresses the estimation of an unknown quantity exploiting the interference among measurements from different sources. These measurements are obtained from the Fourier domain but are sparse and ...
    • Castro, R. L.; Basaure Matsumoto, Kenji Andrés; Palma, S.; Vallejos, J. (South African Institute of Mining and Metallurgy, 2017)
      Mudrushes are sudden inflows of mud ore into underground miningfacilities. They may cause harm to people and equipment, productiondelays, dilution of ore, and mine closure. The aim of this work is to charac-terize, by ...
    • Montejo Sánchez, Samuel; Azurdia Meza, César; Bolufé, Sandy; Céspedes Umaña, Sandra; Soto, Ismael; Souza, Richard Demo (IEEE, 2017)
      Vehicularad hocnetworks (VANETs) have emergedas a paradigm for sharing information among vehicles andinfrastructure that has the potential to provide road safety andtravellers comfort. The bandwidth limitation is one of ...
    • Castruccio, Angelo; Diez, Mikel; Gho, Rayen (Blackwell Publishing Ltd, 2017)
      Volcano morphology has been traditionally studied from a descriptive point of view, but inthis work we took a different more quantitative perspective. Here we used volcano dimensions such asheight and basal radius, together ...
    • Cuevas, Alejandro; Veragua, Alejandro; Español Jiménez, Sonia; Chiang, Gustavo; Tobar, Felipe (IEEE, 2017)
      In the context of bio-acoustic sciences, call detection is a critical task for understanding the behaviour of marine mammals such as the blue whale species (Balaeonoptera musculus) considered in this work. In this paper ...
    • Salgado, Ronie; Bergel, Alexandre (Association for Computing Machinery, 2017)
      Collaborative software development platforms such as GitHub simplify the process of contributing into open source projects by the use of a pull request. The decision of accepting or rejecting a pull request has to be made ...
    • Mira Gebauer, Nicolás F.; Rojo Olea, Erick F.; Mendoza Araya, Patricio A. (IEEE, 2017)
      The presence of both electronic-converter-based and rotating-machine-based energy sources in microgrids poses a challenge for its stable operation. Most of the stability studies in microgrids have been focused on the ...
    • Muñoz, Caterina; Montoto, Francisco; Bustos Jiménez, Javier; Cifuentes, Francisco (IEEE, 2017)
      The Domain Name System (DNS) has evolved to support the exponential growth of the Internet, by relying heavily on a highly distributed infrastructure. Nevertheless, trust between server must exist in order to guarantee ...
    • Cortés Carmona, Marcelo; Mallco Mallco, Abdiel; Palma Behnke, Rodrigo; Calderón Muñoz, Williams; Reyes Marambio, Jorge (IEEE, 2017)
      One of the most noticeable effects on the loss of performance and capacity of thermal systems is caused by the effect of altitude, which causes the density of a compressible fluid and the atmospheric pressure to be ...
    • Jiménez J., Diego; Vives S., María; Jiménez E., Guillermo; Mendoza Araya, Patricio (IEEE, 2017)
      Rural electrification brings economic and social welfare to communities through benefits such as power supply for medical centers, technology access, household tasks improvement and water quality, among others. However, ...
    • Correa Haeussler, José; Hoeksma, Rubén; Schröder, Marc (Springer, 2017)
