    Target Tracking System Using Multiple Cameras and Bayesian Estimation
    (2016-08-29) Redolfi, Javier; González Dondo, Diego; Griffa, Martín; Steiner, Guillermo; Canali, Luis
    In recent years, the increase in amount of camera networks available has led to the rise up of new techniques and applications of signal processing. In this work, an implementation of image sensor network, cameras, for mobile target tracking is shown. More specifically, it is performed an application of particle filter in a distributed way, based on leader agents for state estimation. Finally, simulations are presented, as well as a real experiment made with a camera network to track a mobile platform.

    Synthesis and characterization of new thermosetting polybenzoxazines with other functional groups in the network
    (Journal of Polymer Research, 2018-03-03) Taverna, María E.; Gilbert, Elangeni; Dieser, María Fernanda; Morales, Graciela; Spontón, Marisa; Estenoz, Diana
    The reduction of phenol and/or formalde-hyde consumption during phenolic resin synthesis is of great technological and scientific interest because of its economic and environmental implications. In this work, the addition of sodium lignosulfonate as par-tial replacement of phenol in the phenolic resol base resins used for decorative laminates production is experimentally studied. The work involves: i) the characterization and reactivation of lignosulfonate, ii) the industrial synthesis of traditional and modified resoles by replacement of 10%w/w of phenol, iii) the industrial impregnation of Kraft-type papers with the produced resins, iv) the pro-duction of laminates at laboratory and industrial scale, and, v) the measurement of their final properties. Tensile, bending and impact strength were evaluated. Modified laminates exhibited mechanical properties statistically comparable with those of traditional laminates. Industrial tests were carried out at Centro S.A, San Francisco, Córdoba.

    Effect of Kraft Lignin from Hardwood on Viscoelastic, Thermal, Mechanical and Aging Performance of High Pressure Laminates.
    (Waste and Biomass Valorization, 2017-07-10) Taverna, María E.; Tassara, Oriana; Morán, Juan; Nicolau, Verónica V.; Estenoz, Diana; Frontini, Patricia
    In this work, the synthesis and characterization of phenol-formaldehyde resols modified with 10, 20 and 30 wt% of Kraft lignin (a waste from pulp industry) from hardwood were studied. In all cases, the Kraft lignin was activated by hydroxymethylation. The resols characterization involved industrial measurements of free formaldehyde, viscosity, total solids and density. The resins were used for the industrial impregnation of Kraft-type paper and the production of laboratory laminates. The mechanical and thermal properties of the laminates were determined. Mechanical measurements included tensile, flexural, impact and interlaminar tests. Thermogravimetric and dynamic mechanical analysis were used for the thermal characterization. In addition, the aging of materials in water was studied. No significant differences in mechanical and thermal properties between traditional and modified materials were found with replacement up to 20 wt% of phenol. Modified laminates exhibited better water resistance due to the lignin hydrophobicity. This work was carried out in collaboration with Centro S.A., San Francisco, Córdoba, Argentina, a high pressure-laminates industry.
