    • Brain, Matthew J.; Moya Fuentes, Pablo Sebastian; Kincey, Mark E.; Tunstall, Neil; Petley, David N.; Sepúlveda Valenzuela, Sergio Andrés (AMER Geophysical Union, 2021)
      Earthquakes trigger widespread landsliding in tectonically active landscapes. The effects of strong ground shaking on hillslope stability persist into the post-seismic stage; rates of landsliding remain elevated in the ...
    • Sáez, Miguel; Ruiz Tapia, Sergio (Amer Geophysical Union, 2018)
      T phases from 54 South American earthquakes with M-w > 5.2 are observed at a broadband station on Juan Fernandez Island. We computed the T phase energy flux (TPEF) values of the seismograms. The TPEF values show a large ...
    • San Martín, Jorge; Smaranda, Loredana; Takahashi, Takéo (Elsevier, 2009)
      We consider the approximation of the unsteady Stokes equations in a time dependent domain when the motion of the domain is given. More precisely, we apply the finite element method to an Arbitrary Lagrangian Eulerian ...
    • Gallegos, Javier A.; Duarte Mermoud, Manuel (Elsevier, 2017)
      Conditions for boundedness and convergence of the output error and the parameter error for various Caputo's fractional order adaptive schemes based on the steepest descent method are derived in this paper. To this aim, the ...
    • Attouch, Hedy; Peypouquet, Juan (Springer Verlag, 2019)
      © 2018, Springer-Verlag GmbH Germany, part of Springer Nature and Mathematical Optimization Society. We study the behavior of the trajectories of a second-order differential equation with vanishing damping, governed by the ...
    • San Martín, Jorge; Scheid, Jean-Francois; Takahashi, Takéo; Tucsnak, Marius (SIAM PUBLICATIONS, 2005)
      In this paper, we consider a Lagrange-Galerkin scheme to approximate a two dimensional °uid-rigid body problem. The equations of the system are the Navier- Stokes equations in the °uid part, coupled with ordinary di®erential ...
    • Felmer Aichele, Patricio; Topp Paredes, Erwin (2013)
      In this article we study various convergence results for a class of nonlinear fractional heat equations of the form ⎧⎨ ⎩ ut(t, x)− I[u(t, ·)](x) = f(t, x), (t, x) ∈ (0, T) × Rn, u(0, x) = u0(x), x∈ Rn, where I is a ...
    • Nutz, Marcel; San Martín, Jaime; Tan, Xiaowei (Inst Mathematical Statistics, 2020)
      We study the convergence of Nash equilibria in a game of optimal stopping. If the associated mean field game has a unique equilibrium, any sequence of n-player equilibria converges to it as n -> infinity. However, both the ...
    • Ren, Zhiyuan; Zhu, Lei; Shi, Hui; Yue, Nannan; Li, Di; Zhang, Qizhou; Mardones Pérez, Diego; Wu, Jingwen; Jiao, Sihan; Liu, Shu; Luo, Gan; Xie, Jinjin; Zhang, Chao; Xu, Xuefang (Oxford, 2021)
      Filamentary structures are closely associated with star-forming cores, but their detailed physical connections are still not clear. We studied the dense gas in OMC-3 MMS-7 region in the Orion A molecular cloud using the ...
    • Gallegos, Javier A.; Duarte-Mermoud, Manuel A. (TUBITAK, 2019)
      We establish a characterization of the Lyapunov and Mittag-Leffler stability through (fractional) Lyapunov functions, by proving converse theorems for Caputo fractional order systems. A hierarchy for the Mittag-Leffler ...
    • Grippo, Luciano N.; Matamala Vásquez, Martín; Safe, Martín D.; Stein, Maya (Elsevier, 2016)
      A set of vertices X of a graph G is convex if no shortest path between two vertices in X contains a vertex outside X. We prove that for fixed p >= 1, all partitions of the vertex set of a bipartite graph into p convex sets ...
    • Torres J., Hitschfeld N., Ruiz R.O., Ortiz-Bernardin A. (Springer Science and Business Media Deutschland GmbH, 2020)
    • Xie, Feiyi; Wen, Hong; Wu, Jinsong; Chen, Songlin; Hou, Wenjing; Jiang, Yixin (IEEE Computer Soc, 2020)
      In this article, a convolutional neural network (CNN) enhanced radio frequency fingerprinting (RFF) authentication scheme is presented for Internet of things (IoT). RFF is a non-cryptographic authentication technology, ...
    • Maior C.B.S., dos Santos M.C.M., de Santana J.M.M., de Negreiros A.C.S.V., das Chagas Moura M., Lins I.D., Droguett E.L. (Research Publishing Serviceseditorial@rpsonline.com.sg, 2020)
    • Modarres, Ceena; Astorga, Nicolás; López Droguett, Enrique; Meruane Naranjo, Viviana (John Wiley and Sons Ltd, 2018)
      Recurring expenses associated with preventative maintenance and inspectionproduce operational inefficiencies and unnecessary spending. Human inspec-tors may submit inaccurate damage assessments and physically inaccessibl ...
    • Schultheis, M.; Rojas Arriagada, A.; Cunha, K.; Zoccali, M.; Chiappini, C.; Zasowski, G.; Queiroz, A. B. A.; Minniti, D.; Fritz, T.; García Hernández, D. A.; Nitschelm, C.; Zamora, O.; Hasselquist, S.; Fernández-Trincado, J. G.; Muñoz, R. R. (EDP Sciences, 2020)
      The Galactic center region, including the nuclear disk, has until recently been largely avoided in chemical census studies because of extreme extinction and stellar crowding. Large, near-IR spectroscopic surveys, such as ...
    • Casassus Montero, Simón; Pérez, Sebastián; Osses, Axel; Marino, Sebastián (Oxford University Press, 2019)
      © 2019 The Author(s).The mass of the gaseous reservoir in young circumstellar discs is a crucial initial condition for the formation of planetary systems, but estimates vary by orders of magnitude. In some discs with ...
    • Escobar, Juan; Llanes, Gastón (Academic Press Inc., 2018)
