    The design of a Structural Health Monitoring (SHM) systems is a requirement in the task of improving the safety and maintainability of the structures. Among the multiple techniques available for health monitoring, ...
  • Prediction system for the anticipation of Space Weather events affecting ionosphere and GNSS satellite systems 

    García Rigo, Alberto; Nuñez, Marlon; Qahwaji, Rami; Ashamari, Omar W; Jiggens, Piers; Pérez, Gustau; Hernández Pajares, Manuel; Hilgers, Alain (European Space Agency (ESA), 2015)
    Conference lecture
    Open Access
    The solar activity can be considered one of the main sources of hazards not only affecting launch operations but also the reliability of Global Navigation Satellite Systems (GNSS), such as Galileo, and Satellite Based ...
  • Space Weather Prediction System providing forecasts and alerts on solar flares and SEP events 

    García Rigo, Alberto; Nuñez, Marlon; Qahwaji, Rami; Ashamari, Omar W; Jiggens, Piers; Pérez, Gustau; Hernández Pajares, Manuel; Hilgers, Alain (2015)
    Conference lecture
    Open Access
    A web-based prototype system for predicting Solar Flares and Solar Energetic Particle (SEP) events for its use by space launcher operators or any interested user has been implemented. The main goal of this system, called ...
  • Sensorless force estimation using a neuro-vision-based approach for robotic-assisted surgery 

    Avilés Rivero, Angélica Ivone; Alsaleh, Samar M.; Sobrevilla Frisón, Pilar; Casals Gelpi, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference lecture
    Open Access
    This paper addresses the issue of lack of force feedback in robotic-assisted minimally invasive surgeries. Force is an important measure for surgeons in order to prevent intra-operative complications and tissue damage. ...
  • Counting configuration–free sets in groups 

    Rué Perna, Juan José; Serra Albó, Oriol; Vena Cros, Lluís (2015)
    Conference lecture

    We present a unified framework to asymptotically count the number of sets, with a given cardinality, free of certain configurations. This is done by combining the hypergraph containers methodology joint with arithmetic ...
  • Lissajous curves: an experiment in creative coding 

    Barrière Figueroa, Eulalia (2015)
    Conference lecture

    Do you want to become a creative coder for a day? When artists use a computer to make art, they often experience the need of improving their mathematical skills. On the other hand, students with technical skills are less ...
  • Proyecto, desarrollo y valoración en la UPC de un caso de feedforwarding en campus virtual 

    Fabregat Fillet, Jaume; Pelayo Melero, Ignacio Manuel; Valero Baya, Jordi; Ornat Longarón, Cèsar; Achaerandio Puente, María Isabel; Pineda Soler, Eloi; Buenestado Caballero, Pablo (Universitat Politècnica de València, 2015)
    Conference report
    Open Access
    Docentes de UPC, UB, UAB, UIB, UOC y URV investigamos sobre una evaluación formativa "feedforwarding", que realimente de inmediato, que no se limite al "correcto-incorrecto", que guíe más que resuelva, que sea suficientemente ...
  • Ramsey numbers for empty convex polygons 

    Bautista-Santiago, Crevel; Cano, Javier; Fabila-Monroy, Ruy; Hidalgo-Toscano, Carlos; Huemer, Clemens; Leaños, Jesús; Sakai, Toshinori; Urrutia, Jorge (University of Ljubljana, 2015)

    We study a geometric Ramsey type problem where the vertices of the complete graph Kn are placed on a set S of n points in general position in the plane, and edges are drawn as straight-line segments. We define the empty ...
  • On the disks with diameters the sides of a convex 5-gon 

    Huemer, Clemens; Pérez-Lantero, Pablo (Universitat Politècnica de Catalunya. Departament de Matemàtica Aplicada II (MA2), 2015)
    Conference report
    Restricted access - publisher's policy
    We prove that for any convex pentagon there are two disks, among the five disks having a side of the pentagon as diameter and the midpoint of the side as its center, that do not intersect. This shows that K5 is never the ...
  • Structural health monitoring by means of strain field pattern recognition on the basis of PCA and automatic clustering techniques based on SOM
