In recent years, zirconia ceramics have been used in many applications. Some of them include tool forming due to its high strength and fracture toughness, thermal barrier coatings on turbines engines due to its low thermal ...
CATALA <br/> <br/>La contaminació de les aigües superficials i subterrànies representa el problema mediambiental més greu a què s'ha d'enfrontar la indústria minera, a causa de les denominades aigües àcides de mina (AAM), ...
L'urani es troba present en el medi a baixes concentracions en roques, sòls i aigua, però l'activitat industrial i el desenvolupament de la tecnologia nuclear ha suposat la generació de grans quantitats de residus i zones ...
In this Thesis we present an argument-based model – ProCLAIM – intended to provide a setting for heterogeneous agents to deliberate on whether a proposed action is safe. That is, whether or not a proposed action is expected ...
Due to the problems associated with the generation and storage of hydrogen in portable applications, the use of ammonia fer the on-site production of hydrogen through its catalytic decomposition has been proposed. This ...
El modelo actual del consumo energético basado en la utilización de combustibles fósiles requiere un replanteamiento debido al agotamiento de éstos y a las emisiones de gases contaminantes que generan. La obtención de ...
Access to drinking water is one of the challenges of the 21st century for an increasing number of countries in the world. In Spain, a desalination plant providing between 20% and 30% of Barcelona¿s drinking water has ...
The depletion of fossil fuels and increase of global warming lead to a high demand for alternative energy sources that should be cheap and renewable to fulfill the future energy demand. The photocatalytic generation of H2 ...
Discrete Mathematics, and in particular Graph Theory, has gained a lot of popularity during the last 7 decades. Among the many branches in Graph Theory, graph labelings has experimented a fast development, in particular ...
Cyanobacteria are prokaryotic aerobic photosynthetic microorganisms with the capacity to remove nutrients from wastewater and synthesize a large variety of bioactive compounds and valuable byproducts. Among those valuable ...
In this PhD. Thesis the results of eleven studies about the presence, distribution, and effects of personal care products (PCPs) in the environment are presented with the intention of giving a consolidated vision and to ...
La tesis propone dar una visión de la larga duración en los procesos urbanos de reconversiones implicados en la redefinición del frente marítimo de las ciudades portuarias e investigar las razones de los cambios estructurales ...
Wind turbines components are subject to considerable stresses and fatigue due to extreme environmental conditions to which they are exposed, especially those located offshore. Also, the most common faults present in wind ...
In this dissertation it is solved a problem of optimization in automated systems of production based on robotic cells where the time of completion of parts Cmax is minimized and where there are buffers between pairs of ...
The dynamic behavior of the traffic demand, due to the advent of technologies such as cloud services or Internet of Things (IoT), is increasing. In fact, heterogeneous connections with different characteristics (bandwidth ...
The last decade has witnessed unprecedented changes in parallel and distributed infrastructures. Due to the diminished gains in processor performance from increasing clock frequency, manufacturers have moved from uniprocessor ...
This thesis contributes from the perspective of task-based programming models to the efforts of optimizing I/O intensive applications. Throughout this thesis, we propose programming model abstractions and mechanisms that ...
There is a clear trend nowadays to use heterogeneous high-performance computers, as they offer considerably greater computing power than homogeneous CPU systems. Extending traditional CPU systems with specialized units ...
For the last decade, mobile devices have grown in popularity and became the best-selling computing devices. Despite their high capabilities for user interactions and network connectivity, the computing power of mobile ...
Data Science workflows have become a must to progress in many scientific areas such as life, health, and earth sciences. In contrast to traditional HPC workflows, they are more heterogeneous; combining binary executions, ...
