Els objectius principals d'aquesta tesis són l'avaluació del rendiment a nivell d'enllaç i l'estudi de l'abstracció de l'enllaç pel LTE/LTE-Advanced DL. S’ha desenvolupat un simulador del nivell d'enllaç E-UTRA DL basat ...
The first chapter introduces an approach to machine learning (ML) were data is understood as a network of connected entities. This strategy seeks inter-entity information for knowledge discovery, in contrast with traditional ...
This thesis analyses the relationships between hydrodynamics (and their forcings) and biological variables in Fangar Bay based on in situ observations, numerical models and satellite data. Fangar Bay is a relatively small, ...
Both experimental and numerical studies on Liquid Crystal (LC) infiltrated woodpile Photonic Crystal (PhC) are implemented in this thesis. The most well-known optical phenomenon of PhC is photonic bandgap (PBG). It is ...
The thesis proposes an analysis of the relationship between literature and architecture at the turn of 19th to 20th century. From the verification of the importance of literature and reading in the period previous to ...
This thesis addresses the Ecuadorian cacao value chain through three interrelated chapters. Small producers linked to this chain face significant trade-offs between the two main available varieties for planting: the fine ...
Nurseries growing potted ornamental plants carry an important activity in the overall agricultural production in Catalonia. As a result of the activity developed and agricultural practices adopted by nursery growers ...
Within the paradigm of sustainability, this thesis aims to provide complementary views to the conventional engineering in order to put forward tools that facilitate, on the one hand the search of solutions to improve the ...
Architecture and environment are strongly linked. In Mediterranean countries, the control of radiation is one ofthe most important environmental aspects to take into account, because of the high radiation levels reached ...
Due to the large volume of the processed medium in pilot or industrial cultivation systems, it is difficult to illuminate the entire layer of the culture medium, which results in the formation of dark zones. Due to ...
This dissertation analyses Louis Kahn’s independent work until 1957 period in which he designed the Richards Medical Research Laboratories at the University of Pennsylvania. The Richards Medical Research Laboratories marks ...
Nowadays, it would be very difficult to deny the need to prioritize sustainable development through energy efficiency at all consumption levels. In this context, an energy management system (EMS) is a suitable option for ...
Monitoring and mining real-time network data streams are crucial operations for managing and operating data networks. The information that network operators desire to extract from the network traffic is of different size, ...
In the first part, we formally study the phenomenon of the so-called big bang bifurcations, both for one and two-dimensional piecewise-smooth maps with a single switching boundary. These are a special type of organizing ...
In the context of distributed generation growth, local grids could face operational issues. In that sense, smart grid deployment will give information to local grid operators about grid status at medium and low voltage ...
In order to increase the performance of particle colliders, it is crucial to make the beam sizes at the collision points as small as possible. This causes an increase of the beam size in the region surrounding the collision ...
Many materials of scientific interest show a disordered phase, with their molecules presenting positional disorder, orientational disorder or both. Processes of interest to life also occur in these kind of phases as it is ...
This thesis aims at improving the convergence of iterative solvers, used for algebraic systems coming from the discretization of partial differential equations (PDE), in the context of large scale simulations and high ...
Air pollution is an important topic with a great social impact; it is related with public health, environment and ecology, and climate change. Scientists have developed several models in the last thirty years, and regional ...
Quantum Mechanics was established as the theory of the microscopic world, which allowed to understand processes in atoms and molecules. Its emergence led to a new scientific paradigm that quickly spread to different research ...
