    • On fractional extensions of Barbalat Lemma 
      Gallegos, Javier A.; Duarte Mermoud, Manuel; Aguila Camacho, Norelys; Castro Linares, Rafael (Elsevier, 2015)
      This paper presents Barbalat-like lemmas for fractional order integrals, which can be used to conclude about the convergence of a function to zero, based on some conditions upon its fractional integral. Some examples in ...
    • On Liouville type theorems for fully nonlinear elliptic equations with gradient term 
      Chen, Huyuan; Felmer Aichele, Patricio (Elsevier, 2013)
    • On MAC Protocols Performance for M2M Communications 
      Ortiz-Guerra E., Rojas M.O., Montejo-Sanchez S., Souza R.D., Azurdia-Meza C.A., Cespedes S. (Institute of Electrical and Electronics Engineers Inc., 2020)
    • On minimal forbidden subgraph characterizations of balanced graphs 
      Bonomo, Flavia; Durán Maggiolo, Guillermo; Safe, Martín D.; Wagler, Annegret K. (2013)
      A graph is balanced if its clique-matrix contains no edge–vertex incidence matrix of an odd chordless cycle as a submatrix. While a forbidden induced subgraph characterization of balanced graphs is known, there is no ...
    • On minimizing the makespan when some jobs cannot be assigned on the same machine 
      Das, Syamantak; Wiese, Andreas (Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2017)
      We study the classical scheduling problem of assigning jobs to machines in order to minimize the makespan. It is well-studied and admits an EPTAS on identical machines and a (2 − 1/m)- approximation algorithm on unrelated ...
    • On Mobius Duality and Coarse-Graining 
      Huillet, Thierry; Martínez Aguilera, Servet (Springer, 2016)
      We study duality relations for zeta and Mobius matrices and monotone conditions on the kernels. We focus on the cases of families of sets and partitions. The conditions for positivity of the dual kernels are stated in terms ...
    • On non-coplanar Hohmann transfer using angles as parameters 
      Rincón Rivero, Ángel; Rojo Rubke, Ángel; Lacruz, Elvis; Abellán, Gabriel; Díaz, Sttiwuer (Springer, 2015)
      We study a more complex case of Hohmann orbital transfer of a satellite by considering non-coplanar and elliptical orbits, instead of planar and circular orbits. We use as parameter the angle between the initial and ...
    • On perturbed sweeping process 
      Azzam Laouir, D.; Makhlouf, Amira; Thibault, Lionel (Taylor and Francis, 2016)
      This paper is devoted to the study of a perturbed differential inclusion governed by a sweeping process in a Hilbert space. The sweeping process is perturbed by a sum of a single-valued map satisfying a Lipschitz condition ...
    • On polymorphism for discrete evolutionary dynamics driven either by selection or segregation distortion 
      Huillet, Thierry; Martínez Aguilera, Servet; Möhle, Martin (Springer, 2018-05)
      We revisit some problems arising in the context of multiallelic discrete-time and deterministic evolutionary dynamics driven first by fitness differences and then by segregation distortion. In the model with fitness, we ...
    • On probe 2-clique graphs and probe diamond-free graphs 
      Bonomo, Flavia; Figueiredo, Celina de; Durán Maggiolo, Guillermo; Grippo, Luciano; Safe, Martín; Szwarcfiter, Jayme (Discrete Mathematics and Theoretical Computer Science, 2015)
      Given a class G of graphs, probe G graphs are defined as follows. A graph G is probe G if there exists a partition of its vertices into a set of probe vertices and a stable set of nonprobe vertices in such a way that ...
    • On Reducing Harmonic and Sampling Distortion in Vocal Tract Length Normalization 
      Becerra Yoma, Néstor; Garretón, Claudio; Huenupán, Fernando; Catalán, Ignacio; Wuth Sepúlveda, Jorge (2013)
      This paper proposes a novel feature-space VTLN (vocal tract length normalization) method that models frequency warping as a linear interpolation of contiguous Mel filter-bank energies. The presented technique aims to ...
    • On regions of existence and nonexistence of solutions for a system of p-q-Laplacians 
      Clément, Philippe; García-Huidobro, Marta; Guerra, Ignacio; Manásevich Tolosa, Raúl (IOS PRESS, 2006)
    • On SDE associated with continuous-state branching processes conditioned to never be extinct 
      Fittipaldi, M. C.; Fontbona Torres, Joaquín (2012)
      We study the pathwise description of a (sub-)critical continuous-state branching process (CSBP) conditioned to be never extinct, as the solution to a stochastic differential equation driven by Brownian motion and Poisson ...
    • On semicoercive sweeping process with velocity constraint 
      Adly, Samir; Le, Ba Khiet (Springer, 2018-06)
      In this note, by solving a variational inequality at each iteration, we study the existence of solutions for a class of sweeping processes with velocity in the moving set, originally introduced in a recent paper (Adly et ...
    • On signal representations within the Bayes decision framework 
      Silva, Jorge F.; Narayanan, Shrikanth S. (Elsevier, 2012-05)
      This work presents new results in the context of minimum probability of error signal representation (MPE-SR) within the Bayes decision framework. These results justify addressing the MPE-SR criterion as a complexity-regularized ...
    • ON SOLAR RADIUS VARIATIONS OBSERVED WITH ASTROLABES 
      Noel Plaza, Fernando (SPRINGER, 2005-11)
      Ground-based results on cyclic variations of the apparent solar radius are so far controversial and inconsistent. This is blamed to atmospheric noise which effects can be so severe that even in cases in which the ...
    • On some consistency conditions for geostatistical change-of-support models 
      Emery, Xavier (2007)
      This work deals with a family of geostatistical models used in application fields concerned with a change of support, such as mineral resources evaluation and polluted soil management. Three models are examined: the discrete ...
    • On some graph classes related to perfect graphs: A survey 
      Bonomo-Braberman, Flavia; Durán, Guillermo; Safe, Martín D.; Wagler, Annegret K. (Elsevier, 2020)
      Perfect graphs form a well-known class of graphs introduced by Berge in the 1960s in terms of a min-max type equality involving two famous graph parameters. In this work, we survey certain variants and subclasses of perfect ...
    • On somemixedvariationalprinciplesinmagneto-elastostatics 
      Vogel, Franziska; Bustamante Plaza, Roger; Steinmann, Paul (Elsevier, 2013)
      Some mixed variational formulations are presented for the problem of a deforming and magneto-active body completely surrounded by free space. The possibility of large elastic deformations is considered, in particular due ...
    • On Sorting, Heaps, and Minimum Spanning Trees 
      Navarro, Gonzalo; Paredes, Rodrigo (2006)
      Let A be a set of size m. Obtaining the first k ≤ m elements of A in ascending order can be done in optimal O(m + k log k) time. We present Incremental Quicksort (IQS), an algorithm (online on k) which incrementally gives ...
