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, ...
Transactional memory (TM) is a new optimistic synchronization technique which has the potential of making shared memory parallel programming easier compared to locks without giving up from the performance. This thesis ...
(English) Cardiovascular diseases are the most common cause of death in the world. The heart has a very limited regeneration capacity. Thus, following tissue damage – e.g., myocardial infarction –, heart transplantation ...
L'objectiu d'aquesta tesi és aprofondir en l'estudi d'una certa família de dígrafs, els dígrafs de prefix-cicle, donant nous detalls sobre la seva estructura, noves maneres d'enfocar el seu estudi, i dissenyant bons esquemes ...
Els materials nanoestructats periòdics han ofert, en les dues darreres dècades, un nou marc per a l'estudi de la interacció entre la radiació electromagnètica i la matèria. Aquestes estructures permeten modelar les propietats ...
El trabajo se enmarca dentro del estudio de ciertas propiedades ópticas con vistas a su inclusión en el diseño de dispositivos de conmutación de señales ópticas. En particular se ha prestado atención a los medios que exhiben ...
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 ...
