    • A methodology for virtual human animation 

      FRANCISCO ALEJANDRO MADERA RAMIREZ; CARLOS GASPAR HERRERA ZAPATA; FRANCISCO JOSE MOO MENA
      We propose a method to animate a 3D virtual human generating keyframes of the model and interpolating to achieve a realistic animation. The first two steps refer to the human modeling, the rigging and the skinning. The ...

    • Intelligent platform for non intrusive assistance of elderly people 

      MELCHOR EDOARDO LOPEZ MEJIA; JORGE RICARDO GOMEZ MONTALVO; FRANCISCO JOSE MOO MENA; FRANCISCO ALEJANDRO MADERA RAMIREZ
      In this paper we present PIANI, an Intelligent Platform for Non Intrusive Assistance of Elderly People able to do activities in outdoor environments. PIANI allows inferring the risk level of the activity that an elderly ...

    • Operating system simulator to translate assembler code to machine code 

      ENRIQUE AYALA FRANCO; FRANCISCO ALEJANDRO MADERA RAMIREZ; LUIS RAMIRO BASTO DIAZ
      We analysed and implemented an Operating System software simulator to translate assembler code into machine code. The simulator is a computer program of a virtual machine which contains a computer simplified computer ...

    • Particle simulation with GPUs shading languages 

      FRANCISCO ALEJANDRO MADERA RAMIREZ; FRANCISCO JOSE MOO MENA; ENRIQUE AYALA FRANCO; LUIS FERNANDO CURI QUINTAL
      The usage of GPUs (Graphics Processing Units) in graphics is essential due to their parallel feature to perform operations. In this work we implement a particle simulation program using shading languages to improve the ...

    • Self-collision detection in tubular objects approximated by spheres 

      ENRIQUE AYALA FRANCO; FRANCISCO ALEJANDRO MADERA RAMIREZ; FRANCISCO JOSE MOO MENA
      We investigate the performance of an algorithm to detect selfcollisions in a tubular object approximated by spheres. The approach utilizes the Bounding Volume Hierarchy (BVH) to arrange the spheres and it was implemented ...

    • Sphere approximation for non-tubular object 

      FRANCISCO ALEJANDRO MADERA RAMIREZ; FRANCISCO JOSE MOO MENA; ENRIQUE AYALA FRANCO
      We study the problem of approximating a 3D object with a union of overlapping spheres. We employ a disk filled with rays that comes from the center of the disk and points outwards. The disk traverses the object to detect ...

    • Videojuego para el repaso de fracciones: Tséem Took y la princesa de Uxmal Versión 1.1 

      GENNY ROCIO UICAB BALLOTE; FRANCISCO ALEJANDRO MADERA RAMIREZ; LUIS RAMIRO BASTO DIAZ
      Se expone el diseño de un videojuego didáctico conformadode varias actividades, con el propósito de que los estudiantes de primaria, en especial los educandos de sexto grado, refuercen el estudio de la noción de fracción. ...

    • Web service composition using the bidirectional Dijkstra algorithm 

      FRANCISCO JOSE MOO MENA; RAFAEL HERNANDEZ UCAN; VICTOR EMANUEL DE ATOCHA UC CETINA; FRANCISCO ALEJANDRO MADERA RAMIREZ
      Web services are not always able to fulfill customer requirements on their own, so in those cases it can choose to make a composition of web services. However, this is a complex problem since it must take into account the ...
