(English) Axial forces in columns of moment-resisting frames (MRF) have a paramount role for the seismic performance of these structural systems. Nonetheless, there are significant gaps in the literature entailing the ...
The dynamic response of any structure submerged in water is significantly modified by the effect of added mass. The inertia of the fluid that the body must accelerate during its vibrational motion decreases its natural ...
Coastal areas concentrate very high socio-economic and natural values, which will be highly threatened by climate change, particularly by sea-level rise (SLR). Given the intrinsic characteristics of this zone, appropriate ...
Timber frame structures which constitute an important cultural heritage of many countries, are well known as efficient seismic resistant structures worldwide and are worth to be preserved. Himis is one common traditional ...
El propósito de la presente tesis es estudiar la influencia de la logística inversa en las capacidades de fabricación, refabricación y almacenaje óptimas de un sistema industrial. El interés por la logística inversa ha ...
La utilización de circona tetragonal policristalina estabilizada con 3 % mol de itria (3Y-TZP) para fabricar coronas e implantes ha sufrido una fuerte expansión recientemente debido a las buenas propiedades mecánicas, ...
Nowadays, hydropower plays an essential role in the energy market. With the massive entrance of new renewable sources such as wind or solar power, hydropower is the only renewable generating source that can provide fast ...
Los sistemas de humedales construidos de flujo subsuperficial horizontal (HCFSS) constituyen una tecnología válida para la depuración de aguas residuales urbanas. Uno de los principales objetivos de estos sistemas es ...
Spanish Mediterranean coasts are known as famous tourism destinations and have been under the construction of tourist accommodations and second home developments for several decades. These areas have faced with unsustainability ...
High school teachers face a constant obligation to keep up to date on Information and Communication Technology (ICT). However, no one gives them training or support on how to deal with the problems arising from the use ...
In this thesis, the microstructure and mechanical properties of bulk samples manufactured with nanocrystalline iron powder are analyzed. This iron powder was obtained by a severe plastic deformation process carried in a ...

Knowledge constitutes one of the key intangible assets for organizations. However, the mere possession of knowledge, however valuable it may be, does not necessarily imply obtaining a competitive advantage. It is necessary ...
En esta tesis se han desarrollado microestructuras mediante tratamientos térmicos de 2,5Y-TZP, las cuales con la adición de tensiones residuales de mecanizado, experimentan un aumento de la resistencia y la tenacidad de ...
There is a gap between the potential of ICT incorporated into classrooms and limited renewal of the educational process and thechnology is nothing without pedagogical innovation. ICT/TAC have been incorporated in our univers ...
The Monocentric model of urban structure, characterized by a clear dominance of the CBD (central business district) in terms of concentration of employment and activity, flourished the main theories of the urban economy, ...
(English) Diffractive multifocal intraocular lens typically uses a hybrid refractive-diffractive design that consist of a high-power refractive base lens and a low-power diffractive profile engraved on one of its surfaces. ...
La interacció dels organismes bentònics amb el sediment es relaciona, bàsicament, amb els processos de bioturbació i els de rugositat de fons. Els principals factors implicats en la mobilització de sediment a la plataforma ...
Debido a los actuales niveles de integración que permite la tecnología de fabricación de circuitos integrados, las interconexiones juegan cada vez un papel más importante en el comportamiento de dichos circuitos introduciendo ...
Son bastante conocidas las relaciones entre la pintura de Piet Mondrian y la arquitectura moderna; desde Theo Van Doesburg a John Hejduk, la influencia de su poética ha sido manifiesta. Menos estudiadas han sido las ...
