    • Rosier, Lionel; Bing-Yu Zhang (Elsevier B.V., 2008-02)
      This Note investigates the boundary controllability, as well as the internal controllability, of the complex Ginzburg–Landau equation. Null-controllability results are derived from a Carleman estimate and an analysis based ...

    • Dávila, Juan; Dupaigne, Louis; Farina, Alberto (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011-07-01)
      We prove regularity and partial regularity results for finite Morse index solutions u is an element of H-1 (Omega) boolean AND L-P(Omega) to the Lane-Emden equation -Delta u = vertical bar u vertical bar(P-1)u in Omega.
    • Palma, Sergio; Ihle Bascuñán, Christian; Tamburrino Tavantzis, Aldo; Dalziel, Stuart (American Institute oh Physics, 2016)
      A series of sedimentation experiments and numerical simulations have been conducted to understand the factors that control the final angle of a static sediment layer formed by quasi-monodisperse particles settling in an ...
    • Pola Contreras, Daniel; Navarrete Echeverría, Hugo; Orchard Concha, Marcos; Rabié Durán, Ricardo; Cerda Muñoz, Matías; Olivares Rubio, Benjamín; Silva Sánchez, Jorge; Espinoza, Pablo; Pérez Mora, Aramis (IEEE, 2015)
      We present the implementation of a particle-filteringbased prognostic framework that utilizes statistical characterization of use profiles to (i) estimate the state-of-charge (SOC), and (ii) predict the discharge time ...
    • Acuña, David E.; Orchard Concha, Marcos (Elsevier, 2017)
      This paper presents a novel prognostic method that allows a proper characterization of the uncertainty associated with the evolution in time of nonlinear dynamical systems. The method assumes a state-space representation ...
    • Olivares, Benjamín E.; Muñoz, Cerda; Orchard Concha, Marcos; Silva, Jorge F. (IEEE, 2013)
      This paper presents the implementation of a particlefiltering- based prognostic framework that allows estimating the state of health (SOH) and predicting the remaining useful life (RUL) of energy storage devices, and ...
    • Díaz Turra, César; Quintero, Vanessa; Pérez, Aratnis; Jaramillo Montoya, Francisco; Burgos Mellado, Claudio Danilo; Rozas, Heraldo; Orchard Concha, Marcos; Sáez Hueichapan, Doris; Cárdenas Dobson, Roberto ((IEEE) Institute of Electrical and Electronics Engineers, 2020)
      Nowadays, electric vehicles such as cars and bicycles are increasing their popularity due to the rising environmental consciousness. The autonomy required by these means of transport has marked a significant and steady ...
    • Riquelme Hernández, Mario; Quataert, Eliot; Verscharen, Daniel (American Astronomical Society, 2015)
      We use particle-in-cell simulations to study the nonlinear evolution of ion velocity space instabilities in an idealized problem in which a background velocity shear continuously amplifies the magnetic field. We simulate the ...
    • López, R. A.; Lazar, M.; Shaaban, S. M.; Poedts, S.; Yoon, P. H.; Viñas, A. F.; Moya, P. S. (Institute of Physics Publishing, 2019)
      We report the first results from particle-in-cell simulations of the fast-growing aperiodic electron firehose instability driven by the anisotropic bi-Kappa distributed electrons. Such electrons characterize space plasmas, ...
    • Alvarado Espina, Eduardo; Morales Olivares, Rommy; Rivera Vargas, Pablo (Universidad Complutense de Madrid, 2020)
      La crisis económica del 2008, cuyos peores efectos se percibieron en los países desarrollados, reavivó la disputa política por la hegemonía ideológica. Con ella se evidenció la disfunción existente entre bienes materiales ...
    • Bustamante, Sebastián; Stein, Maya (Elsevier, 2018-06)
      We show that for all l, k, n with l <= k/2 and (k-l) dividing n the following hypergraph-variant of Lehel's conjecture is true. Every 2-edge-colouring of the k-uniform complete hypergraph kappa((k))(n) on n vertices has ...
    • Rodríguez Bustamante, Sebastián Fernando; Corsten, Jan; Frankl, Nora; Pokrovskiy, Alexey; Skokan, Jozef (Siam, 2020)
      Confirming a conjecture of Gyarfas, we prove that, for all natural numbers k and r, the vertices of every r-edge-colored complete k-uniform hypergraph can be partitioned into a bounded number (independent of the size of ...
    • Bustamante, Sebastián; Corsten, Jan; Frankl, Nóra (Springer, 2020)
      Extending a result of Rado to hypergraphs, we prove that for all s,k,t is an element of N$$s, k, t \in {\mathbb {N}}$$\end{document} with k >= t >= 2 the vertices of every r=s(k-t+1)-edge-coloured countably infinite complete ...
    • Schaudt, Oliver; Stein, Maya (Wiley-Liss Inc., 2019)
      © 2018 Wiley Periodicals, Inc. We show that any complete k-partite graph G on n vertices, with k≥3, whose edges are two-coloured, can be covered with two vertex-disjoint monochromatic paths of distinct colours, given that ...
    • Hernández Pellicer, Rodrigo; Rodríguez, G. (Institute of Physics Publishing, 2017)
      Numerical simulations were used to study the dynamics of a passive conservedscalar quantity entrained by a self-propelling viscous vortex ring. The trans-port and mixing process of the passive scalar variable were studied ...
    • Fernández, R.; Gulick, S.; Domack, E.; Montelli, A.; Leventer, A.; Shevenell, A.; Frederick, B.; Frederick, B. (Elsevier B.V., 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 ...

      We consider a generic interaction-redistribution model of vegetation dynamics to investigate the formation of patchy vegetation in semi-arid and arid landscapes. First, we perform a weakly nonlinear analysis in the ...
    • Gagie, Travis; He, Meng; Navarro, Gonzalo (Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2017)
      Let f: [1.n] → [1.n] be a function, and i: [1.n] → [1.σ] indicate a label assigned to each element of the domain. We design several compact data structures that answer various queries on the labels of paths in f. For ...
