Metodología sistemática para el diseño innovador de un nuevo modelo de cambio ferroviario basado en TRIZ: cruzamiento y desvío
|
upm |
El objetivo de este trabajo es diseñar un nuevo sistema para reducir el riesgo de descarrilamiento en los cruces, que son puntos críticos en las líneas ferroviarias. Los cruces son un elemento común en las líneas convencionales de los sistemas ferroviarios actuales y son el único punto de la vía donde existe una discontinuidad. Nuestra propuesta se basa en añadir un elemento al cruce que ocupe ... |

upm |
La estratégica y escarpada geografía que ofrece la Parte Alta de Cuenca fue determinante para que los musulmanes decidieran fundar una ciudad que, posteriormente, fue conquistada por los cristianos. Las familias nobles fueron unas de las responsables del auge económico y poblacional, siendo el siglo XVI, su máximo apogeo. A partir del siglo XVII se sucedieron epidemias, crisis económicas y guer... |

Model-Based Input Energy Control for Reproducible AISI 316L Laser Deposited Tracks

upm |
n the Directed Energy Deposition (DED) process, when the mass flow of metal particles is relatively high, the thickness of the layers increases, leading to a more productive process. The higher the mass flow is, the more difficult it becomes to get a stable melt pool. The accumulation of residual heat in the previously consolidated material constitutes a thermal input affecting the balance at t... |

Several gold deposits in the eastern region of Cuba are genetically related to the island arc- and the ophiolitic complex formation. These have been studied and exploited since the time of the Spanish colonization in the mid-sixteenth century. These deposits belong to the Aguas Claras-Guajabales mineral field in the Holguín Province (Cuba) and lie in an elongated zone approximately 15 km in len... |

Soil anisotropy is a property of geomaterials that affects significatively most geotechnical constructions: embankments, retaining walls, tunnels, tailings dams, foundations, etc. Gravity effects, mode of deposition, compaction processes, origin of components of soils, fabric, microstructure or stress paths have an influence on soil anisotropic mechanical behaviour. In all these cases, the avai... |
