A high performance biometric system based on image morphological analysis
(2014)At present, many of the algorithms used and proposed for digital imaging biometric systems are based on mathematical complex models, and this fact is directly related to the performance of any computer implementation of ... -
High resolution, week-long, locomotion time series from Japanese quail in a home-box environment
(2016-06-07)Temporal and spatial patterns of locomotion reflect both resting periods and the movement from one place to another to satisfy physiological and behavioural needs. Locomotion is studied in diverse areas of biology such as ... -
ICME international survey on teachers working and learning through collaboration : June 2016
(2016)This article presents preliminary results from a survey commissioned for ICME 13 (2016) focusing on “Teachers Working and Learning Through Collaboration”. It takes as a starting point a previous survey, commissioned for ... -
Implementation of an F-statistic all-sky search for continuous gravitational waves in Virgo VSR1 data
(2014)We present an implementation of the F -statistic to carry out the first search in data from the Virgo laser interferometric gravitational wave detector for periodic gravitational waves from a priori unknown, isolated ... -
Implementation of several mathematical algorithms to breast tissue density classification
(2014)The accuracy of mammographic abnormality detection methods is strongly dependent on breast tissue characteristics, where a dense breast tissue can hide lesions causing cancer to be detected at later stages. In addition, ... -
Improved upper limits on the stochastic gravitational-wave background from 2009-2010 LIGO and Virgo data
(2014)Gravitational waves from a variety of sources are predicted to superpose to create a stochastic background. This background is expected to contain unique information from throughout the history of the Universe that is ... -
Improving furosemide polymorphs properties through supramolecular complexes of beta-cyclodextrin
(2014)In this work, complexes of β-cyclodextrin and the two solid forms of furosemide were prepared and characterized for their potential pharmaceutical applications, with the interactions between the two compounds being studied ... -
In vivo EDXRF scanning analysis of human nail
(2014-09)This paper presents the results of a new technique forin vivoenergy dispersive X-rayfluorescence (EDXRF) scan analysis, applied to humanfingernails. The scan employs a specially designed EDXRF spectrometer, which allows a ... -
The index of symmetry of compact naturally reductive spaces
(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
(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
(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 ... -
Influence of the incorporation of fibers in biscuit dough on proton mobility characterized by time domain NMR
(2016)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
(2014-12-16)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
(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
(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
(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
(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
(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
(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
(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 ...
