    • Infante, Alejandro; Bergel, Alexandre (Association for Computing Machinery, 2017)
      Modern object-oriented programming languages greatly alleviate the memory management for programmers. Despite the efficiency of garbage collection and Just-In-Time program analyzes, memory still remains prone to be wasted. ...
    • Loncomilla, Patricio; Ruiz del Solar, Javier; Martínez, Luz (2016)
      The main goal of this survey is to present a complete analysis of object recognition methods based on local invariant features from a robotics perspective; a summary which can be used by developers of robot vision applications ...
    • Robbes, Romain; Róthlisberger, David; Tanter, Éric Pierre (Springer, 2015)
      As software evolves, data types have to be extended, possibly with new data variants or new operations. Object-oriented design is well-known to support data extensions well. In fact, most popular books showcase data ...
    • Robbes, Romain; R'othlisberger, David; Tanter, Éric Pierre (Springer, 2014)
      As software evolves, data types have to be extended, possibly with new data variants or new operations. Object-oriented design is well-known to support data extensions well. In fact, most popular books showcase data ...
    • Pérez, Sebastián; Casassus Montero, Simón; Benítez-Llambay, P. (Oxford University Press, 2018)
      Empirical evidence of planets in gas-rich circumstellar discs is required to constrain giant planet formation theories. Here we study the kinematic patterns which arise from planet- disc interactions and their observability ...
    • Cecioni, Giovanni (Universidad de Chile, 1978)
      Geológicamente esta región se puede dividir en dos fajas dispuestas aproximadamente N-S; la oriental constituida por una serie de formaciones arenosas y arcillosas del Cretacico más alto, hasta la base del Maastrichtiano; ...
    • Tlidi, M.; Clerc Gavilán, Marcel; Escaff, D.; Couteron, P.; Messaoudi, M.; Khaffou, M.; Makhoute, A. (Royal Society Publishing, 2018)
      We report for the first time on the formation of spirals like vegetation patterns in isotropic and uniform environmental conditions. The vegetation spirals are not waves and they do not rotate. They belong to the class of ...
    • Sepúlveda Soto, Fabián; Guzmán Silva, Diego; Rosas, Edgardo; Vicencio, Rodrigo A.; Falcón, Claudio (Nature, 2020)
      We report on the observation and characterization of broad-band waveguiding of surface gravity waves in an open channel, in the shallow water limit. The waveguide is constructed by changing locally the depth of the fluid ...
    • Cordaro Cárdenas, Enrique; Gálvez, D.; Laroze, D. (Elsevier, 2016)
      In analysis of experiments carried during September 2008 using secondary cosmic ray detectors located in Chacaltaya (Bolivia) and Niteroi (Brazil), Augusto et al. (2010) showed an increase in the intensity of charged ...
    • Elicer Cortés, Juan; Ruz, C.; Hernández, R. H.; Pavageau, Michel; Boyer, Denis (PERGAMON-ELSEVIER SCIENCE LTD, 2005-02)
      An experimental study of the instability modes of a laminar axisymmetric thermal plume under symmetrical controlled disturbances of varicose type was carried out. The Schlieren technique was used to investigate the considered ...
    • Breitfelder, J.; Kervella, Pierre; Mérand, A.; Gallenne, A.; Szabados, L.; Anderson, R. I.; Willson, M.; Le Bouquin, J.-B. (EDP SCIENCES, 2015)
      Context. The distance of pulsating stars, in particular Cepheids, are commonly measured using the parallax of pulsation technique. The different versions of this technique combine measurements of the linear diameter variation ...
    • Breitfelder, J.; Mérand, A.; Kervella, Pierre; Gallenne, A.; Szabados, L.; Anderson, R. I.; Le Bouquin, J.-B. (ESO, 2016-03)
      Context. The distance to pulsating stars is classically estimated using the parallax-of-pulsation (PoP) method, which combines spectroscopic radial velocity (RV) measurements and angular diameter (AD) estimates to derive ...
    • Anderson, Joseph P.; Covarrubias, R. A.; James, P. A.; Hamuy Wackenhut, Mario; Habergham, S. M. (Royal Astronomical Society, 2010)
      We present constraints on the progenitor metallicities of core-collapse supernovae. To date, nearly all metallicity constraints have been inferred from indirect methods such as metallicity gradients in host galaxies, ...
    • Carraro, Giovanni; Fuente, Marcos R. de la; Villanova, S.; Bidin, C. Moni; Fuente, Marcos C. de la; Baumgardt, H.; Solivella, G. (2007)
      Context. Observations indicate that present-day star formation in the Milky Way disk takes place in stellar ensembles or clusters rather than in isolation. Bound, long-lived stellar groups are known as open clusters. They ...
    • Villenave, M.; Menard, F.; Dent, W. R. F.; Duchene, G.; Stapelfeldt, K. R.; Benisty, M.; Boehler, Y.; Van der Plas, G.; Pinte, C.; Telkamp, Z.; Wolff, S.; Flores, C.; Lesur, G.; Louvet, F.; Riols, A.; Dougados, C.; Williams, H.; Padgett, D. (EDP, 2020)
      Aims. We aim to study vertical settling and radial drift of dust in protoplanetary disks from a different perspective: an edge-on view. An estimation of the amplitude of settling and drift is highly relevant to understanding ...
    • Van der Plas, Gerrit; Pérez M., Sebastián; Dent, William R. F.; Fomalont, Ed; Hagelberg, Janis; Hales, Antonio; Jordán, Andrés; Mawet, Dimitri; Ménard, Francois; Wootten, Al; Wilner, David; Hughes, A. Meredith; Schreiber, Matthias R.; Girard, Julien H.; Ercolano, Bárbara; Canovas, Héctor; Román, Pablo E.; Casassus Montero, Simón; Salinas, Vachail (Nature Publishing Group, 2013-01-10)
      The formation of gaseous giant planets is thought to occur in the first few million years after stellar birth. Models1 predict that the process produces a deep gap in the dust component (shallower in the gas2, 3, 4). ...
    • Jenkins, James Stewart; Díaz, M.; Jones, H. R. A.; Butler, R. P.; Tinney, C. G.; O’Toole, S. J.; Carter, B. D.; Wittenmyer, R. A.; Pinfield, D. J. (Oxford University Press, 2015)
      We report the detection of sixteen binary systems from the Anglo-Australian Planet Search. Solutions to the radial velocity data indicate that the stars have companions orbiting with a wide range of masses, eccentricities ...
    • Hawkins, E.; Frame, D.; Harrington, L.; Joshi, M.; King, A.; Rojas Corradi, María Heloísa; Sutton, R. (American Geophysical Union, 2020)
      Changes in climate are usually considered in terms of trends or differences over time. However, for many impacts requiring adaptation, it is the amplitude of the change relative to the local amplitude of climate variability ...
