  • Textural image classification of foams based on variographic analysis 

    Mesa, D.; Kracht, W.; Díaz, G. (Elsevier, 2016)
    Froths can be characterised according to several features, such as colour, bubble size distribution, velocity, mobility or texture. In the case of texture, there are some alternatives that can be used to analyse and classify ...
  • Biocryptography 

    Figureau, A.; Soto, M. A.; Tohá, J. (Churchill Livingstone, 2000)
    A new cryptology that uses biomolecules as carriers of hidden information is described here. The huge dimension of biopolymers permits the insertion there of private messages and the rapidity and specificity of biomolecular ...
  • Fast DNA sequencing 

    Figureau, A.; Soto, M. A.; Tohá, J. (Elsevier, 2000)
    A method for fast nucleotide sequencing is described. It is based in the selection of well-known small oligomers able to be hybridized with the unknown target. The selected oligomers are afterwards ordered following a ...
  • Effects of translational coupling on dissipative localized states 

    Campo, F. del; Haudin, F.; Rojas, R. G.; Bortolozzo, Umberto; Clerc Gavilán, Marcel; Residori, S. (2012)
    Nonequilibrium localized states under the influence of translational coupling are studied experimentally and theoretically. We show that localized structures are deformed and advected in the direction of the coupling, ...
  • The seismic network of Chile 

    Barrientos, Sergio (Seismological Society of America, 2018)
    Chile is frequently affected by large and potentially tsunamigenic and damaging earthquakes as a result of rapid convergence of the Nazca plate beneath the South America plate. Ten M 8 or larger earthquakes have occurred ...

    Liao, Run-Fa; Wen, Hong; Wu, Jinsong; Song, Huanhuan; Pan, Fei; Dong, Lian (Wiley-Hindawi, 2018)
    This paper presents a multi-time channel prediction system based on backpropagation (BP) neural network with multi-hidden layers, which can predict channel information effectively and benefit for massive MIMO performance, ...
  • The impact of a buried high-velocity layer in the seismic site amplification of the city of Llolleo, Chile 

    Sáez, Miguel; Pastén Puchi, César; Ruiz, Sergio; Salomón, José (Seismological Society of America, 2018)
    We studied the influence of a buried high-velocity layer (HVL) on the surface ground amplification of the city of Llolleo, Chile, where large peak ground accelerations were observed during the 1985 M-w 8.0 Valparaiso and ...
  • The chilean GNSS network: current status and progress toward early warning applications 

    Báez, J. C.; Leyton, F.; Troncoso, C.; Campo, F. del; Bevis, M.; Vigny, C.; Moreno, M.; Simons, M.; Kendrick, E.; Parra, H.; Blume, F. (Seismological Society of America, 2018)
    Chile is one of the world's most seismically active regions and is therefore extensively studied by the earthquake sciences. The great length of the country hosts a variety of measurement systems allowing for the ...
  • Sensitivity and effectiveness analysis of incentives for concentrated solar power projects in Chile 

    Simsek, Yeliz; Mata Torres, Carlos; Guzmán, Amador M.; Cardemil Iglesias, José; Catalán Escobar, Rodrigo Ignacio (Elsevier, 2018)
    Northern Chile has excellent conditions to develop concentrated solar power projects. Although solar irradiation makes a significant contribution to production in the region, solar thermal projects need some support ...
  • Preface to the focus section on geophysical networks and related developments in Latin America 

    Barrientos, Sergio; Pérez-Campos, Xyoli (Seismological Society of America, 2018)
  • Past ice stream and ice sheet changes on the continental shelf off the Sabrina Coast, East Antarctica 

    Fernández Vásquez, Rodrigo; Gulick, S.; Domack, E.; Montelli, A.; Leventer, A.; Shevenell, A.; Frederick, B. (Elsevier, 2018)
    Our understanding of the response of the Antarctic ice sheet to climate and ocean changes requires the improvement of current ice-atmosphere-ocean models and the accurate determination of boundary conditions such as ice ...
  • Overidentification tests for the exogeneity of instruments in discrete choice models 

    Guevara Cue, Cristian (Elsevier, 2018)
    Endogeneity is often present in discrete choice models, precluding the consistent estimation of the model parameters. To correct for this problem, the researcher needs to gather exogenous instrumental variables, which ...
  • Nanoscale partitioning of Ru, Ir, and Pt in base-metal sulfides from the Caridad chromite deposit, Cuba

  • Loving and loathing: portrayals of school mathematics in young adult fiction 

    Darragh, Lisa (Natl Council Teachers Mathematics-NCTM, 2018)
