Innovation is an essential activity for the competitiveness of firms. It has also contributed positively to increasing the living standards of millions of people. However, it is widely recognized that innovation co-produces ...
The study of the elastic, dielectric and piezoelectric non-linear behavior in PZT-based and KNN-based piezoelectric ceramics represent the main goal of this work. Both systems present a perovskite-like structure. Several ...
In recent years hard coatings have acquired a significant importance in the microstructural and micromechanical design of forming tools. Among the wide range of surface modification techniques, physical and chemical vapour ...
Las estrategias de ahorro de energía en edificios, posibilitan la disminución de los costos de operación y/o mantenimiento de los mismos a lo largo de su vida útil. Sin embargo, el confort térmico de los usuarios se ve en ...
European sea bass (Dicentrarchus labrax) aquaculture is a thriving industry in Spain where it reached about 23,500 t and a market value of approximately 133 million euros. However, most of the sea bass farms produce a high ...

The upper ocean circulation is the area of confluence of two major vertical cells: the large-scale overturning Atlantic Meridional Overturning Circulation (AMOC) and the regional relatively shallow Subtropical Cells (STCs). ...
(English) Marine heterotrophic flagellates (HF) are very small (2-5 µm) unpigmented protists that are dominant bacterial grazers in the ocean, where they link the transfer of carbon from bacterial cells to higher trophic ...
Modern processors use out-of-order processing logic to achieve high performance in Instructions Per Cycle (IPC) but this logic has a serious impact on the achievable frequency. In order to get better performance out of ...
The aluminum alloy AA2024-T3, u sed extensively in the aerospace industry, dueto the heterogeneous microstructures intentionally designed to optím ize the m echanical properties, is very susceptible to localízed corros ...
(English) This thesis presents the Tychonis framework, a solution to the limitations faced by existing software packages used in space missions to identify geometric events. The framework is designed to integrate with ...
La tesis doctoral que se desarrolla a continuación se centra en la réplica de negocio que, en contextos de pobreza, crean valor para la sociedad (en términos de reducción de pobreza) y la empresa. La incorporación de las ...
Many scientific, industrial and medical applications require the measurement of different physical parameters in order to collect information about the spatially distributed status of some process. Very often this information ...
We present a cell-centred model for the simulation of multicellular soft tissues that takes into account the underlying active process at the cytoskeletal level, and allows for active and passive cell-cell reorganisation ...
Roman architect Mario Ridolfi (1904-1984) made a substantial contribution to the transformation of European cities and to collective housing after the Second World War. For a period of twenty years, he used the city of ...
Intensive farming often leads environmental consequences. This is the case of the study area of this thesis: the Empordà, a region with a variety of intensive crops (fruits, cereals, forage,...) and manifest problems of ...
The probabilistic seismic risk assessment in terms of economic losses for building portfolios aims at the estimation of the probability distribution functions of losses. This can be done for a specific seismic event ...
The main goal of the work presented in this thesis is to describe the definition of interoperability mechanisms between rights expression languages and policy languages. Starting from languages interoperability, the intention ...
(English) The historical analysis performed has shown that jet fires have been the origin of a high number of domino effect accidents, both in the process industry and in the transportation of flammable fluids by pipelines ...
