      The Ayllu Solar project’s main goal is to foster the sustainable development of rural/urban communities in Arica & Parinacota region, northern Chile, by means of using solar energy. This 5-year project is based on three ...
    • Sacaan, Rafael; Rudnick, Hugh; Lagos, Tomás; Ordóñez Pizarro, Fernando; Navarro Espinosa, Alejandro; Moreno Vieyra, Rodrigo (IEEE, 2017)
      Due to the stochastic nature of equipment failures, the accurate assessment of power system reliability is a complex task. Consequently, the optimal selection of new network infrastructure to improve reliability is even ...
    • Moncada de la Rosa, Daniel; Baker, Darcy; Bodnar, Robert J. (Elsevier, 2017)
      Theoretical, experimental and observation data provide strong evidence that boiling is the dominant depositional mechanism in many low to intermediate sulfidation epithermal precious metals deposits. Textural and petrographic ...

      Automatic Speech Recognition (ASR) field has improved substantially in the last years. We are in a point never saw before, where we can apply such algorithms in non-ideal conditions such as real classrooms. In these scenarios ...
    • Pradenas Márquez, Bastián; Araya, Isidora; Clerc Gavilán, Marcel; Falcón Beas, Claudio; Gandhi, Punit; Knobloch, Edgar (American Physical Society, 2017)
      We report on an experimental, theoretical, and numerical study of slanted snaking of spatially localized parametrically excited waves on the surface of a water-surfactant mixture in a Hele-Shaw cell. We demonstrate ...
    • Vogel, E. E.; Saravia, G.; Pastén Guzmán, Denisse; Muñoz Gálvez, Víctor (Elsevier, 2017)
      Three seismic sequences of several thousand earthquakes each are analyzed by means of a tunable information recognizer known as wlzip. These sequences are different both in the geographical coverage and the time span, ...
    • Bauer, Franz E.; Treister, Ezequiel; Schawinski, Kevin; Schulze, Steve; Luo, Bin; Alexander, David M.; Brandt, William N.; Comastri, Andrea; Forster, Francisco; Gilli, Roberto; Kann, David Alexander; Maeda, Keiichi; Nomoto, Ken'ichi; Paolillo, Maurizio; Ranalli, Piero; Schneider, Donald P.; Shemmer, Ohad; Tanaka, Masaomi; Tolstov, Alexey; Tominaga, Nozomu; Tozzi, Paolo; Vignali, Cristian; Wang, Junxian; Xue, Yongquan; Yang, Guang (Oxford University Press, 2017)
      © 2017 The Authors. We report on the detection of a remarkable new fast high-energy transient found in the Chandra Deep Field-South, robustly associated with a faint (mR = 27.5mag, zph ~2.2) host in the CANDELS survey. The ...
    • Cárdenas, Roberto; Pérez, Marcelo; Clare, Jon (Institute of Electrical and Electronics Engineers Inc., 2017)
      Solar-based energy generation has increased by more than ten times over the same period. In total, worldwide electrical energy consumption increased by approximately 6340 TWh from 2003 to 2013. To meet the challenges created ...
    • Leiva Illanes, Roberto; Catalán Escobar, Rodrigo Ignacio; Cardemil Iglesias, José; Alarcón Padilla, Diego César (Elsevier, 2017)
      A thermoeconomic assessment of the joint production of electricity, fresh-water, cooling and heat for a solar polygeneration plant is carried out. The aims are to assess the actual cost of each product, to conduct a ...
    • Rubio Carrasco, André; Castro Arellano, Iván; Mills, James N.; List, Rurik; Ávila Flores, Rafael; Suzán, Gerardo (Public Library of Science, 2017)
      High species diversity of the potential animal host community for a zoonotic pathogen may reduce pathogen transmission among the most competent host, a phenomenon called the “dilution effect”, but the mechanisms driving ...
    • Nova, David; Estévez Valencia, Pablo (IEEE, 2017)
      In this contribution we propose a new regularization method for the Generalized Matrix Learning Vector Quantization classifier. In particular we use a nuclear norm in order to prevent oversimplifying/over-fitting and ...
    • Vergara, Jorge R.; Estévez Valencia, Pablo (IEEE, 2017)
      Segment Growing Neural Gas (Segment-GNG) has been recently proposed as a new spatiotemporal quantization method for time series. Unlike traditional quantization algorithms that are prototype-based, Segment-GNG uses segments ...
    • Li, Yong; Astroza, Rodrigo; Conte, Joel P.; Soto Muñoz, Pedro (Elsevier, 2017)
      In this paper, nonlinear finite element model updating (FEMU) is performed to study the prediction accuracy of a state-of-the-art finite element (FE) model of a seismic isolated bridge (SIB). The seismic isolator model ...
    • Rojas, Félix; Kennel, Ralph; Cárdenas Dobson, Jesús Roberto; Repenning, Ricardo; Clare, Jon C.; Díaz, Matías (IEEE, 2017)
