Unmanned Aircraft Systems (UAS) are rapidly gaining attention due to the increasing potential of their applications in the civil domain. UAS can provide great value performing environmental applications, during emergency ...
This work discloses new insights into the formation and evolution of Mg -carbonates as well as carbonation processes of Mg-rich oxides and silicates with the aim of providing a safe and permanent anthropogenic CO2 storage, ...
Formulación espectral de la radiación en coordenadas cartesianas, cilíndricas y esféricas. Aplicación de la formulación a problemas de diagnostico de antenas, análisis del efecto de radomos y transformación campo próximo ...
The intention and purpose of the present thesis is to prepare a series of protective coatings using some conducting polymers (CPs) as corrosion inhibitors. The use of organic paints is the most common method for corrosion ...
Wireless community networks (WCN) are specially vulnerable to routing forwarding failures because of their intrinsic characteristics: use of inexpensive hardware that can be easily accessed; managed in a decentralized way, ...
The image of the city is a collection of shapes and volumes in continuous evolution and transformation. Changes in the visual of the cities are appreciated on the long term, as it shape changes by the construction of new ...
Las antenas son dispositivos esencialmente de banda estrecha; es decir, su comportamiento es altamente dependiente de la frecuencia de operación. La relación entre la longitud de onda de trabajo y el tamaño de la antena ...
(English) In this study, the Weierstrass fractal function was used to model the surface roughness of railway tracks and, subsequently, the static coefficient of friction (COF) for Hertzian rail-wheel contact and cylinder-plane ...
La investigación realizada en esta tesis se ha centrado en la caracterización de la fractura de materiales compuestos por una matriz de polipropileno homopolímero isotáctico y diferentes fracciones de partículas laminares ...
Este trabajo se ubica en una perspectiva marcada por dos fuentes de inspiración y exigencia, que se complementan mutuamente: La primera está relacionada con el campo tecnológico y la segunda viene del ambiente científico. ...
La aleación Ti6Al4V es el biomaterial más utilizado para el reemplazo de tejidos duros, debido a su alta biocompatibilidad y a sus propiedades mecánicas. Sin embargo, al ser bioinerte no se une directamente con el hueso. ...
The main issue of the thesis is to discuss the method of building relationships between architecture and city through analyzing projects by Barcelona architects. There are two hypothesizes of the thesis: fragment and ...
DE LA TESIS<br/><br/>La presente tesis tiene por objetivo retratar parte de la crítica y de la teoría arquitectónica comúnmente llamada Posmoderna, a través del análisis de la IBA - Internationale Bauausstellung - ...
Modern guidelines for design and assessment of reinforced concrete structures under seismic and other extreme loads require nonlinear analysis. The complex structural response can be obtained by means of three-dimensional ...
(English) Cycles in the construction sector and economy disguise what appears to advance in occupational risk prevention when, unfortunately, the AECO sector maintains very high accident rates. The zero accident target is ...
Spatial Big Data is considered an essential trend in future scientific and business applications. Indeed, research instruments, medical devices, and social networks generate hundreds of peta bytes of spatial data per year. ...
In order to create autonomous characters it is necessary to solve the problem of moving agents between two locations, at both the global and local navigation levels. Global navigation has two main components: the path ...
Este estudio se ha centrado en las diversas fases de proyecto y la primera etapa de la construcción del Camp Nou, entre 1954 y 1957. Con la intención de ampliar al máximo la capacidad de localizar variables e indeterminaciones ...
Coffee is the most traded food in the world. The coffee industry has a great economic and social relevance worldwide. The sensory and functional properties of the product are highly important for the consumers, and therefore, ...
