    Article
    Accés restringit per política de l'editorial
    Despite recent advances in surveying techniques, publicly available Digital Elevation Models (DEMs) of terrains are low-resolution except for selected places on Earth. In this paper we present a new method to turn ...
  • Visualization of large molecular trajectories 

    Duran Rosich, David; Hermosilla Casajus, Pedro; Ropinski, Timo; Kozliková, Barbora; Vinacua Pla, Álvaro; Vázquez Alcocer, Pere Pau (2018-09-06)
    Article
    Accés obert
    The analysis of protein-ligand interactions is a time-intensive task. Researchers have to analyze multiple physico-chemical properties of the protein at once and combine them to derive conclusions about the protein-ligand ...
  • A general illumination model for molecular visualization 

    Hermosilla Casajus, Pedro; Vázquez Alcocer, Pere Pau; Vinacua Pla, Álvaro; Ropinski, Timo (2018-06)
    Article
    Accés restringit per política de l'editorial
    Several visual representations have been developed over the years to visualize molecular structures, and to enable a better understanding of their underlying chemical processes. Today, the most frequently used atom-based ...
  • Visual analysis of protein-ligand interactions 

    Vázquez Alcocer, Pere Pau; Hermosilla Casajus, Pedro; Guallar, Víctor; Estrada, Jorge; Vinacua Pla, Álvaro (2018-06)
    Article
    Accés restringit per política de l'editorial
    The analysis of protein-ligand interactions is complex because of the many factors at play. Most current methods for visual analysis provide this information in the form of simple 2D plots, which, besides being quite space ...

    Mobile devices have experienced an incredible market penetration in the last decade. Currently, medium to premium smartphones are relatively affordable devices. With the increase in screen size and resolution, together ...
  • Linear buckling analysis of perforated cold-formed steel storage rack columns by means of the generalised beam theory 

    Casafont Ribera, Miguel; Bonada Bo, Jordi; Pastor Artigues, María Magdalena; Roure Fernández, Francisco; Susín Sánchez, Antonio (2017-03)
    Article
    Accés obert
    The investigation attempts to adapt a be am finite element procedure based on the Generalised Beam Theory (GBT) to the analysis of perforated columns. The presence of perforations is taken into account through the use of ...
  • Gemelli-obturator complex in the deep gluteal space: an anatomic and dynamic study 

    Balius, Ramon; Susín Sánchez, Antonio; Morros, Carles; Pujol, Montse; Pérez Cuenca, Dolores; Sala Blanch, Xavier (2017-12-07)
    Article
    Accés obert
    Objective: To investigate the behavior of the sciatic nerve during hip rotation at subgluteal space. Materials and methods: Sonographic examination (high-resolution ultrasound machine at 5.0–14 MHZ) of the gemelli-obturator ...
  • Coherent multi-layer landscape synthesis 

    Argudo Medrano, Óscar; Andújar Gran, Carlos Antonio; Chica Calaf, Antonio; Guerin, Eric (Springer, 2017-05-08)
    Article
    Accés obert
    We present an efficient method for generating coherent multi-layer landscapes. We use a dictionary built from exemplars to synthesize high-resolution fully featured terrains from input low-resolution elevation data. Our ...
  • Interactive GPU-based generation of solvent-excluded surfaces 

    Hermosilla Casajús, Pedro; Krone, Michael; Guallar, Víctor; Vázquez Alcocer, Pere Pau; Vinacua Pla, Álvaro; Ropinski, Timo (Springer, 2017-05-08)
    Article
    Accés obert
    The solvent-excluded surface (SES) is a popular molecular representation that gives the boundary of the molecular volume with respect to a specific solvent. SESs depict which areas of a molecule are accessible by a specific ...
  • Bifurcation diagram of Saddle/Spiral bimodal linear systems 

    Ferrer Llop, Josep; Peña Carrera, Marta; Susín Sánchez, Antonio (2017-01-01)
    Article
    Accés obert
    We complete the study of the bifurcations of saddle/spiral bimodal linear systems, depending on the respective traces T and t: one 2-codimensional bifurcation; four kinds of 1-codimensional bifurcations. We stratify the ...
  • Colonic content: effect of diet, meals, and defecation 

    Bendezú García, Álvaro; Mego, Marianela; Monclús Lahoya, Eva; Merino, Xavi; Accarino Garaventa, Anna María; Malagelada Benapres, Juan Ramon; Navazo Álvaro, Isabel; Azpiroz Vidaur, Fernando (2017-01-29)
    Article
