In flexible manufacturing systems, fast feedback from simulation solutions is required for effective tool path planning and parameter optimization. In the particular sub-domain of laser heating/cutting of thin rectangular plates, current state-of-the-art methods include frequency-domain (spectral) analytic solutions that greatly reduce the required...

Point-cloud-to-mesh registration estimates a rigid transformation that minimizes the distance between a point sample of a surface and a reference mesh of such a surface, both lying in different coordinate systems. Point-cloud-to-mesh-registration is an ubiquitous problem in medical imaging, CAD CAM CAE, reverse engineering, virtual reality and many...

In geometric modelling and finite element analysis (FEA) of lattice materials, the datasets are usually massive, and thus intractable for even the most basic workpieces. Since slender and thin shapes are involved, the size of traditional 3D finite elements is minute, and thus the model sizes explode. 3D modelling of slender shapes is only accepted...

Nuevos retos en el desarrollo de interfaces plásticas de usuario han emergido debido a las características inherentes a los contextos ubicuos y su creciente diversidad. Los retos son aún mayores cuando se están desarrollando interfaces para plataformas educativas modulares como Moodle, las cuales son un conjunto de módulos independientes, cada uno...

"TAG," in Spanish: Tecnología, Aprendizaje y Gestión (Technology, Learning and Management) is an Ubiquitous Learning model that aims to be a point of reference for higher education institutions in their transformation processes for educational innovation. The model is based on three dimensions: Technology, Learning and Management, which are assesse...

Resumen—TAG es un modelo de aprendizaje ubicuo que pretende convertirse en un referente para las instituciones de educación superior en sus procesos de transformación para la innovación educativa. El modelo está basado en tres dimensiones: Tecnología, Aprendizaje y Gestión, las cuales son valoradas a través de la identificación de categorías y prop...

TAG, in Spanish: Tecnología, Aprendizaje y Gestión (Technology, Learning and Management) is an ubiquitous learning model that aims becoming a point of reference for higher education institutions within their transformation processes in educational innovation. The model is built on three dimensions: Technology, Learning and Management, which are ass...

This article introduces a set of conceptual guidelines for the construction of the model "TAG", in Spanish: Tecnología, Aprendizaje y Gestión (Technology, Learning and Management). The model seeks to determine the levels of ubiquity in higher education institucions. This proposal arises from the review of experiences in the development of strategie...

Different strategies for performing string lookups have been developed and deployed during the evolutionary scientific process. These are the results of both the development of technology and the need for improvement of previously existing solutions. Hence, the string lookup problem has been well studied and the respectful amount of good solutions...

The construction of a concept map consists of enumerating a list of concepts and - a more difficult task - determining the linking phrases that should connect the concepts to form meaningful propositions. Appropriate word selection, both for concepts and linking phrases, is key for an accurate knowledge representation of the user's understanding of...

Triangulations of a connected subset F of parametric surfaces S(u, v) (with continuity C2 or higher) are required because a C0 approximation of such F (called a FACE) is widely required for finite element analysis, rendering, manu- facturing, design, reverse engineering, etc. The triangul ation T is such an approx- imation, when its piecewise linea...

Resumen—El NTP es un protocolo de comunicaciones cuya finalidad es sincronizar el reloj de las diferentes máquinas de una red con la hora universal. Actualmente se reconoce la importancia de la sincronización de los relojes en las investigaciones forenses, pues de esta manera se permite la reconstrucción de los hechos. Sin embargo, no siempre los r...
