    • Fronts and localized structures in a liquid-crystal-light-valve with optical feedback 
      Residori, S.; Petrossian, A.; Nagaya, T.; Riera, C. S.; Clerc Gavilán, Marcel (ELSEVIER, 2004-12-01)
      We show that in a liquid-crystal-light-valve with optical feedback the Freedericksz transition displays a subcritical character. Experimentally, we determine the extension of the bistable region and we study the propagation ...
    • Fully adaptive particle filtering algorithm for damage diagnosis and prognosis 
      Rabiei, Elaheh; López Droguett, Enrique; Modarres, Mohammad (MDPI, 2018)
      A fully adaptive particle filtering algorithm is proposed in this paper which is capable of updating both state process models and measurement models separately and simultaneously. The approach is a significant step toward ...
    • Fully coupled "online" chemistry within the WRF model 
      Grell, Georg A.; Peckham, Steven E.; Schmitz, Rainer; McKeen, Stuart A.; Frost, Gregory; Skamarock, William C.; Eder, Brian (PERGAMON-ELSEVIER SCIENCE LTD, 2005-12)
      A fully coupled "online" Weather Research and Forecasting/Chemistry (WRF/Chem) model has been developed. The air quality component of the model is fully consistent with the meteorological component; both components use the ...
    • Fully dynamic metric access methods based on hyperplane partitioning 
      Navarro, Gonzalo; Uribe Paredes, Roberto (PERGAMON-ELSEVIER SCIENCE LTD, 2011-06)
      Metric access methods based on hyperplane partitioning have the advantage, compared to the ball partitioning-based ones, that regions do not overlap. The price is less flexibility for controlling the tree shape, especially ...
    • Fully functional static and dynamic succinct trees 
      Navarro, Gonzalo; Sadakane, Kunihiko (ACM, 2014)
      We propose new succinct representations of ordinal trees and match various space/time lower bounds. It is known that any n-node static tree can be represented in 2n + o(n) bits so that a number of operations on the tree ...
    • Fully functional suffix trees and optimal text searching in BWT-Runs bounded space 
      Gagie, Travis; Navarro, Gonzalo; Prezza, Nicola (Assoc Computing Machinery, USA, 2020)
      Indexing highly repetitive texts-such as genomic databases, software repositories and versioned text collections-has become an important problem since the turn of the millennium. A relevant compressibility measure for ...
    • Fully well-balanced, positive and simple approximate Riemann solver for shallow water equations 
      Berthon, C.; Chalons, C.; Cornet, S.; Sperone, Gianmarco (Springer, 2016)
      The present work is focused on the numerical approximation of the shallow water equations. When studying this problem, one faces at least two important issues, namely the ability of the scheme to preserve the positiveness ...
    • Functional medium dependence of the nonrelativistic optical model potential 
      Arellano Sepúlveda, Hugo; Bauge, E. (2007)
      By examining the structure in momentum and coordinate space of a two-body interaction spherically symmetric in its local coordinate, we demonstrate that it can be disentangled into two distinctive contributions. One of ...
    • Fundamental parameters of six neglected old open clusters 
      Carraro, Giovanni; Subramaniam, Annapurni; Janes, Kenneth A. (BLACKWELL, 2006-09-21)
      In this paper, we present the first BV I CCD photometry of six overlooked old open clusters (Berkeley 44, NGC 6827, Berkeley 52, Berkeley 56, Skiff 1 and Berkeley 5) and derive estimates of their fundamental parameters by ...
    • THE FUNDAMENTAL PLANE EVOLUTION OF ACTIVE GALACTIC NUCLEUS HOST GALAXIES 
      Woo, Jong-Hak; Urry, C. Megan; Lira Teillery, Paulina; van der Marel, Roeland P.; Maza Sancho, José (2004-12-20)
      We measured the stellar velocity dispersions of 15 active galactic nucleus (AGN) host galaxies at redshifts as high as 0.34. Combining these with published velocity dispersion measurements from the literature, we study the ...
    • Fundamental solutions and dual boundary element methods for fracture in plane Cosserat elasticity 
      Atroshchenko, Elena; Bordas, Stéphane P. A. (Royal Soc, 2015)
      In this paper, both singular and hypersingular fundamental solutions of plane Cosserat elasticity are derived and given in a ready-to-use form. The hypersingular fundamental solutions allow to formulate the analogue of ...
    • Fundamental solutions and Liouville type theorems for nonlinear integral operators 
      Felmer Aichele, Patricio; Quaas, Alexander (Elsevier, 2011)
      In this article we study basic properties for a class of nonlinear integral operators related to their fundamental solutions. Our goal is to establish Liouville type theorems: non-existence theorems for positive entire ...
    • Further observations of quasars in ESO/SERC field 927 
      Clowes, Roger G.; Campusano, Luis E.; Graham, Matthew J. (BLACKWELL SCIENCE LTD, 1999-10-11)
      We present the spectra and redshifts of 62 quasars, from observations made with the Cerro Tololo Inter-American Observatory (CTIO) 4-m Blanco Telescope. These quasars form part of a total sample of 118 (with 56 having been ...
    • Fusion of local normalization and Gabor entropy weighted features for face identification 
      Cament Riveros, Leonardo; Castillo, Luis E.; Pérez, Juan E.; Galdámes, Francisco J.; Pérez Flores, Claudio (Elsevier, 2014)
      Face recognition is one of the most extensively studied topics in image analysis because of its wide range of possible applications such as in surveillance, access control, content-based video search, human–computer ...
    • Future changes in the free tropospheric freezing level and rain–snow limit: The case of central Chile 
      Mardones, Piero; Garreaud Salazar, René (MDPI, 2020)
      The freezing level in the free troposphere often intercepts the terrain of the world's major mountain ranges, creating a rain-snow limit. In this work, we use the free tropospheric height of the 0 degrees C isotherm (H0) ...
    • Fuzzing to Estimate Gas Costs of Ethereum Contracts 
      Soto D., Bergel A., Hevia A. (Institute of Electrical and Electronics Engineers Inc., 2020)
    • Fuzzy Arithmetic for the DC Load Flow 
      Cortés Carmona, Marcelo; Palma Behnke, Rodrigo; Jiménez Estévez, Guillermo Andrés (IEEE, 2010-02)
