Aquest treball vol ser una aportació positiva a la teoria general del Manteniment Industrial. <br/>La teoria del Manteniment Industrial és un camp de la coneixença tècnica que encara ha de ser desbrossat d'influències que ...
(English) In 2018, following a theoretical prediction from 2011, it was found that stacking two layers of graphene with a relative twist angle of 1.1° between them leads to multiple new properties. At this so-called magic ...
Esta tesis describe el diseño, la fabricación y la caracterización óptica de sistemas plasmónicos resonantes capaces de confinar y aumentar campos de luz en la escala manométrica. En primer lugar, se utilizaron modelos ...
En este trabajo se ha desarrollado un cálculo vectorial sobre estructuras discretas, análogo al de los modelos continuos. Para ello se ha considerado como espacio subyacente un multigrafo finito o variedad discreta y se ...
Esta tesis se divide en dos partes. La primera parte contiene el estudio de tres pesos o profundidades, asociados a conjuntos finitos de puntos en el plano: el peso definido por las capas convexas, convex depth (introducido ...
Considering the importance of shipping in world trade, the proficient and competent seafarers employed in the maritime industry play a key role in ensuring the international transport of goods by sea. The safety of the ...
Electrification hybrid systems (wind-photovoltaic systems) are a suitable option to supply electricity independently in isolated communities. To design these systems, there are recent mathematical models that provide the ...
The research is conducted for single-family social housing in the city of Saltillo, Coahuila, Mexico, taking into account different general or simplified procedures applied at the energy certification of new housing, ...
El problema tratado, conocido como “Hoist Scheduling Problem”, pretende determinar la programación de una grúa, y ocasionalmente la secuencia de elementos en una línea de producción. En este caso, los objetos se desplazan ...
Las líneas de fabricación de productos mixtos, muy frecuentes en los entornos JIT (Just-in-Time) y DS (Douki Seisan), permiten tratar diversas variantes de uno o más productos. Esta flexibilidad condiciona el orden en que ...
Esta tesis cubre un conjunto de objetivos de investigación relacionados con la adquisición, la medida, la representación y el procesado de la información de color contenida en la imagen digital. La caracterización de los ...
Twinning induced plasticity (TWIP) steels possess both, very high tensile strength and large elongation together with high formability and an outstanding high strain hardening. The unique combination of its distinctive ...
La investigación de los materiales constitutivos de obras de arte, en la que se encuadra esta tesis, es una de las aplicaciones de la espectroscopía Raman que ha ido creciendo en importancia en las últimas décadas. El ...
(English) In this thesis, the mechanical behavior of parts manufactured by Material Extrusion Modeling (MEX) has been evaluated, using a copolimer of polylactic acid (PLA) and polyhydroxybutyrate (PHB), commercially known ...
The thesis is located in two (2) key areas of knowledge: The Software Process Improvement (SPI Software Process Improvement) and Process Change (PDC) at Process Software (PDS) r.Aethods of .Analysis and Cost-Efficiency ...
The starting point of this dissertation is the realization of two facts. On one side, the need of methodologies to develop the research around social aspects of Sustainable Development (SD). Social aspects have been ...
(English) This doctoral thesis investigates the causes that induce (micro)seismicity as a result of hydraulic stimulation in fractured low-permeability rock. Understanding such phenomenon is of paramount importance to ...
Waters from mines (acid mine drainage-AMD), contain elevated concentrations of SO-24, Fe and other contaminant metals, which can persist in the environment during centuries. The purpose of AMD treatments is to retain metals ...
