This thesis focuses on the long time behaviour of solutions to Fisher-KPP reaction-diffusion equations involving fractional diffusion. This type of equation arises, for example, in spatial propagation or spreading of ...
Composite materials are gaining popularity as an alternative to classical materials in many different applications. Moreover, their design is even more flexible due to the potential of additive ...
Plastic based materials are widely used for packaging applications. However, disposal of such petroleum-based materials e.g. polyethylene (PE) and polypropylene (PP) has become a huge threat to the environment due to its ...
The research area of this doctoral thesis is determined by the interaction between legal and technical disciplines such as the Industrial Property (IP) and the industrial or product design respectively. The area they have ...
Ultrafine grain size Armco iron has been obtained through severe plastic deformation through equal channel angular pressing (ECAP) at room temperature, using a die with interna! angle et> = 90 º, and an angle 4J = 37 º ...
One of the most complex and unsolved problems in physics is the glass transition problem, in which the resulting state, the glass, exhibits unique and anomalous properties. During the transition, a kinetic freezing phenomenon ...
This dissertation describes a novel unconventional self-adaptive hardware architecture with capacity for parallel processing. For scalability issues, this bioinspired architecture is based on a regular array of homogeneous ...
The growing need for wireless connectivity is pushing the massive adoption and usage of Wireless Local Area Networks (WLANs) based on the IEEE 802.11 standard (Wi-Fi), leading to dense deployments of individual, uncoordinated ...
Les expectatives dels usuaris en relació a la quantitat i qualitat del serveis de xarxa estan creixent ràpidament. En canvi, desenvolupar e implantar nous serveis de xarxa (serveis que operen a nivell de xarxa) seguint el ...
The PhD research project is framed within the plan of industrial doctorates of the “Generalitat de Catalunya”. During the investigation, most of the work was carried out at the facilities of the vehicle manufacturer SEAT, ...
This work proposes design energy spectra in terms of an equivalent velocity, intended for regions with design peak acceleration 0.3 g or higher. These spectra have been derived through linear and nonlinear dynamic analyses ...
In applications for generic medicinal products the concept of bioequivalence is fundamental. Two medicinal products, i.e. a test and a reference drugs containing the same active substance are considered bioequivalent if ...
Esta tesis partió de la constatación por parte del autor que todo el contenido técnico de un proyecto de arquitectura se vierte principalmente en su documentación gráfica. Sin embargo esta documentación adolece de muchos ...
The present investigation is about the development of a construction system of vertical residential wall's lining, and it is focused on the rehabilitation of the characteristic features of elements and on the implementation ...
This thesis based on classical models of student satisfaction and their antecedents in the field of higher education aims to deepen and develop a new marketing model for higher education. The antecedents of students' ...
Les ciutats d'avui en dia es caracteritzen per un progressiu creixement de la població dins un territori físic limitat. Aquest creixement comporta problemes diversos, com ara la falta d'autocontenció de la ciutat; la ...
The city is faced, each time in a more urgent way, to aboard the contemporary tendency of think and act on it in the horizon of the sustainability paradigm, fully understood not only under environmental, economic and social ...
In recent years, society has begun to take a new view of its relations with the surrounding environment, and in particular has become aware of the need to ensure the sustainability of the oceans and their biodiversity. ...
Energy input spectra applicable to the seismic design of structures in moderate-to-high seismicity regions such as Colombia are proposed. They are derived from the bilinear envelope of individual spectra obtained for 144 ...
Based on technology and science developments as a way of knowing the world, our way of life and the way we interact with the environment have been transformed, in the last two and a half centuries. These changes imply ...
