    • The index of symmetry of compact naturally reductive spaces 

      Olmos, Carlos Enrique; Reggiani, Silvio Nicolás; Tamaru, Hiroshi (2014)
      We introduce a geometric invariant that we call the index of symmetry, which measures how far is a Riemannian manifold from being a symmetric space. We compute, in a geometric way, the index of symmetry of compact naturally ...
    • Inequality between size and angular momentum for bodies 

      Dain, Sergio Alejandro (2014-01-31)
      A universal inequality that bounds the angular momentum of a body by the square of its size is presented and heuristic physical arguments are given to support it. We prove a version of this inequality, as consequence of ...
    • Inequality between size and charge in spherical symmetry 

      Anglada, Pablo Rubén; Dain, Sergio Alejandro; Ortiz, Omar Eduardo (2016)
      We prove that, for a charged spherically symmetric body, twice the radius is always strictly greater than the charge of the body. We also prove that this inequality is sharp. Finally, we discuss the physical implications ...

      The effect of fiber addition on the distribution and mobility of protons in biscuits is studied by using low resolution time domain Nuclear Magnetic Resonance (TD-NMR). The proportion of flour is reduced in order to ...
    • Influence of β-cyclodextrin on the Properties of Norfloxacin Form A

      Cyclodextrins are able to form host-guest complexes with hydrophobic molecules to result in the formation of inclusion complexes. The complex formation between norfloxacin form A and β-cyclodextrin was studied by exploring ...
    • Information extraction with active learning : a case study in legal text 

      Cardellino, Cristian Adrián; Villata, Serena; Alonso i Alemany, Laura; Cabrio, Elena (2015)
      Active learning has been successfully applied to a number of NLP tasks. In this paper, we present a study on Information Extraction for natural language licenses that need to be translated to RDF. The final purpose of our ...
    • Initial dynamics of initial solid-liquid interface in presence of a thermal gradient 

      Xu, M.; Fabietti, Luis María Rodolfo; Song, Younggil; Tourret, Damien; Karma, Alain S.; Trivedi, Rohit K. (2014)
      In directional solidification experiments an alloy is placed in the thermal gradient assembly and kept stationary to achieve a steady-state thermal profile. During this time an interface motion occurs that is experimentally ...
    • Interfaz visual para un Autocolimador Nikon 6D mediante procesamiento de imágenes con precisión sub-píxel : un caso de estudio 

      Schürrer, Clemar Aldino; Flesia, Ana Georgina; Bergues, Guillermo Juan; Ames, Lucas Guillermo; Canali, Luis Rafael (2014)
      Este documento tiene el objetivo de describir el potencial de una interfaz visual básica en un Autocolimador del tipo Nikon 6B/6D, para reemplazar al operario en una medición de calidad metrológica. La interfaz visual ...
    • Internal - External stimulus competition in a system of interacting moving particles : persuasion vs propaganda 

      Clementi, Natalia Carolina; Revelli, Jorge Alberto; Sibona, Gustavo Javier (2015)
      We propose a general nonlinear analytical framework to study the effect of an external stimulus in the internal state of a population of moving particles. This novel scheme allows us to study a broad range of excitation ...
    • Internal dosimetry for alpha emitters radiopharmaceuticals in biological tissue studied with the FLUKA code 

      Valente, Mauro Andrés; Malano, Francisco Mauricio; Pérez, Pedro Antonio (2014)
      Nuclear medicine clinical practices for neoplasic disease diagnose and treatment are based on the incorporation of α, β and γ radiotracers and radiopharmaceuticals, which might be associated with potential damage. Thus, ...
    • Interpolation of geometric structures compatible with a pseudo Riemannian metric 

      Fernández Culma, Edison Alberto; Godoy, Yamile Alejandra; Salvai, Marcos Luis (2016)
      Let (M, g) be a pseudo Riemannian manifold. We consider four geometric structures on M compatible with g: two almost complex and two almost product structures satisfying additionally certain integrability conditions. For ...
    • Interpreting natural language instructions using language, vision and behavior 

      Benotti, Luciana; Lau, Tessa; Villalba, Martín Federico (2010)
      We define the problem of automatic instruction interpretation as follows. Given a natural language instruc- tion, can we automatically predict what an instruction follower, such as a robot, should do in the environment to ...
    • Intrinsic angular momentum for radiating spacetimes which agrees with the Komar integral in the axisymmetric case 

      Gallo, Emanuel; Moreschi, Osvaldo Mario (2014)
      Here, we present a new definition of intrinsic angular momentum at future null infinity, based on the charge-integral approach. This definition is suitable for the general case of radiating spacetimes without symmetries, ...
