    • Borges, Marcos R. S.; Pino Urtubia, José; Araujo, Renata M. (SPRINGER, 2006-05)
      Decisions are frequently sent to implementers without the context that guided them. It should not be a surprise, then, that results are not as expected. The lack of supplementary information and a common context produces ...
    • Goles Chacc, Eric,; Meunier, P.-E.; Rapaport Zimermann, Iván; Theyssier, G. (Elsevier, 2011)
      The notions of universality and completeness are central in the theories of computation and computational complexity. However, proving lower bounds and necessary conditions remains hard in most cases. In this article, ...
    • Serban, Ioan; Céspedes Umaña, Sandra; Marinescu, Corneliu; Azurdia Meza, César; Gómez, Juan S.; Sáez Hueichapán, Doris (IEEE, 2020)
      Progress in Microgrid (MG) research has evolved the MG concept from classical, purely MG power networks to more advanced power and communications networks. The communications infrastructure helps control and manage the ...
    • Moreno, Jenny; Lara, Alejandro; Torres, Mauricio (Elsevier Ltd, 2019)
      This paper examines the role of community resilience during the emergency response after the 2010 Chile earthquake and tsunami. El Morro – a fishing community that managed to survive the tsunami in the Talcahuano region – ...
    • Ramírez Cabrera, Héctor; Seeger, Alberto; Sossa Aguirre, David (2013)
      This paper establishes a commutation result for variational problems involving spectral sets and spectral functions. The discussion takes places in the context of a general Euclidean Jordan algebra.

      The structure and properties have been comprehensively studied for metallocene copolymers of propylene-1-hexene (CiPH) and propylene-1-octadecene (CiPOD). The comonomer content constitutes the most important factor ...
    • Garay Brignardello, Guido; Moran, James M.; Rodríguez, Luis F. (1993-08-20)
      We present observations of the (2, 2) and (3, 3) inversion transitions of ammonia toward a group of compact H II regions near l = 10-degrees.5, b = 0-degrees.0, made at 4'' resolution using the VLA. We detected three ...

      A pathway to the formation of planetesimals, and eventually giant planets, may occur in concentrations of dust grains trapped in pressure maxima. Dramatic crescent-shaped dust concentrations have been seen in recent ...

      A pathway to the formation of planetesimals, and eventually giant planets, may occur in concentrations of dust grains trapped in pressure maxima. Dramatic crescent-shaped dust concentrations have been seen in recent radio ...
    • Feuilloley L., Fraigniaud P., Montealegre P., Rapaport I., Rémila É., Todinca I. (Association for Computing Machineryacmhelp@acm.org, 2020)
    • Marino Estay, Sebastián; Casassus Montero, Simón; Perez, Sebastián; Lyra, W.; Roman, P.; Avenhaus, H.; Wright, C. M.; Maddison, S. T. (The American Astronomical Society, 2015-11-01)
      The formation of planetesimals requires that primordial dust grains grow from micron- to kilometer-sized bodies. Dust traps caused by gas pressure maxima have been proposed as regions where grains can concentrate and ...
    • Marino Estay, Sebastián; Casassus Montero, Simón; Pérez, Sebastián; Lyra, W.; Román, P.; Avenhaus, H.; Wright, C. M.; Maddison, S. T. (IOP Publishing, 2015)
      The formation of planetesimals requires that primordial dust grains grow from micron- to km-sized bodies. Dust traps caused by gas pressure maxima have been proposed as regions where grains can concentrate and grow fast ...
    • Garay Brignardello, Guido; Rodríguez, Luis F. (1990-10-10)
      The VLA was used to map the NH3 emission in the lines of the (J,K) = (2,2) and (J,K) = (3,3) inversion transitions toward the warm molecular cloud associated with the compact H II region G34.3 + 0.2. The main HF line of ...
    • Brisaboa, NievesR; Ladra, Susana; Navarro, Gonzalo (Elsevier, 2013)
      Many relevant Web mining tasks translate into classical algorithms on the Web graph. Compact Web graph representations allow running these tasks on larger graphs within main memory. These representations at least provide ...
    • Brisaboa, Nieves; De Bernardo, Guillermo; Navarro, Gonzalo; Rodeiro, Tirso; Seco, Diego (Institute of Electrical and Electronics Engineers Inc., 2018)
      We introduce a new technique for the efficient management of large sequences of multi-dimensional data, which takes advantage of regularities that arise in real-world datasets and supports different types of aggregation ...
    • Chávez, Edgar; Navarro, Gonzalo (ELSEVIER SCIENCE BV, 2005-07-01)
      he metric space model abstracts many proximity search problems, from nearest-neighbor classifiers to textual and multimedia information retrieval. In this context, an index is a data structure that speeds up proximity ...
    • Dolbeault, Jean; Felmer Aichele, Patricio; Mayorga Zambrano, J. (SPRINGER, 2008-09)
      Interpolation inequalities of Gagliardo-Nirenberg type and compactness results for self-adjoint trace-class operators with finite kinetic energy are established. Applying these results to the minimization of various free ...
