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 ...
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 ...
