The development of the present Ph.D. thesis implied the preparation of PLA and nanoclay reinforced PLA films as well as the application of different thermo-mechanical treatments. Two commercial grade PLA matrices were ...
En esta tesis doctoral se analiza la estructura y morfología inducida en láminas y placas delgadas obtenidas por distintos procesos de transformación. Éstas placas y láminas se prepararon en distintos espesores utilizando ...
Muestras de cobre electrolítico (ETP) y refinado al fuego (FRHC) previamente recocidas durante 30 minutos a una temperatura de 600 ºC, fueron sometidas a presión en canal angular de sección constante (ECAP) a temperatura ...
La tesi presenta una nova teoria i una metodologia per a la verificació formal de propietats de seguretat en sistemes temporitzats. El correcte funcionament d'aquests sistemes no només depèn d'un conjunt de propietats ...
La arquitectura doméstica ofrece un testimonio fundamental para conocer los rasgos que definen una determinada sociedad, ya que la transformación del espacio y el comportamiento desplegado en él, son aspectos estrechamente ...
Glassy phases play an important role in our daily life and in many industries such as the food, pharmaceutical, and construction and are responsible for certain vital mechanisms in living species. Whereas crystals are solid ...
The nature of the glass transition and of the glassy state is a fundamental and still unsolved problem of condensed matter physics. Many liquids can be supercooled below their melting point without crystallizing, that is, ...
La transmisión asistida por relay o transmisión cooperativa es una nueva técnica de diversidad espacial donde aparece un elemento nuevo (un relay o un usuario cooperativo) en la tradicional transmisión punto a punto (fuente ...
The work presented in this dissertation is a compendium of articles based on three main applications of advanced statistical methodologies on real-world complex datasets. The first application concerns wildfire effects ...
As high performance computing (HPC) systems continue to grow, their fault rate increases. Applications running on these systems have to deal with rates on the order of hours or days. Furthermore, some studies for future ...
In this thesis, we have investigated the impact of parametric variations on the behaviour of one performance-critical processor structure - embedded memories. As variations manifest as a spread in power and performance, ...
In the last decades, semiconductor industry has fostered a fast downscale in technology, propelling the large scale integration of CMOS-based systems. The benefits in miniaturization are numerous, highlighting faster ...
Fast and Complex Data Memory systems has become a necessity in modern computational units in today's integrated circuits. These memory systems are integrated in form of large embedded memory for data manipulation and ...
Este trabajo aborda un periodo de la historia moderna de Catalunya centrado en el papel de la arquitectura dentro del campo de las construcciones parroquiales. Se trata de un estudio interdisciplinario que plantea temas ...
In recent years, industries have chosen to invest in technology with the aim of making their processes more efficient and thus offering market products of higher quality. Nowadays it is very common for companies to use ...
Persistent organic pollutants (POPs) constitute an heterogeneous group of chemical substances of great environmental relevance. Its persistence, bioaccumulation, long-range transport potential and negative effects on health ...
(English) The future quantum Internet will allow the transfer of quantum states between remote locations. However, bridging large distances is a challenging task due to losses in optical fibres. A promising approach to ...
(English) Monitoring the atmospheric boundary layer (ABL) is a matter of interest for many applications, such as weather forecasting, pollutant-dispersion models and wind energy. The ABL is the most turbulent part of the ...
The growing concern over environmental pollution in recent decades has placed increasing focus on research into the development of sustainable processes associated with the removal of contaminants in waters. Water is scarcer ...
Una base de datos de 33 km de registros de túnel de EPB en la zona de Barcelona se ha examinado en detalle desde el punto de vista de recambio de herramientas de corte y rendimiento de la excavación mecanizada. La base de ...
