In the coming decades, global warming will affect the biogeochemical cycles evolution, particularly the carbon cycle. In this context, it is necessary to gain knowledge on the Earth natural mechanisms to relieve the ...
Numerical methods aid significantly the engineering efforts towards the conservation of existing masonry structures and the design of new ones. Among them, macro-mechanical finite element methods based on the smeared crack ...
The growth in world population has led to a significant increase in the generation of wastes (solid, liquid and gaseous). Waste gas is probably the major issue in the case of waste treatment, due to the fact that once the ...
This thesis deals with uncertainty in radar-based precipitation estimation and nowcasting in two ways: its quantification in a probabilistic manner, and its reduction in the precipitation estimates. A straightforward way ...
L'objectiu bàsic del present treball és, el de, partint de l'estudi de Martínez-Quintanilla, plantejar un sistema informatitzat per al traçat de la perspectiva curvilínia de pantalla cilíndrica, capaç de poder representar, ...
The increasing amount of data and the number of nodes in large-scale environments require new techniques for information management. Examples of such environments are the decentralized infrastructures of Computational ...
The growth in user demand for higher mobile data rates is driving Mobile Network Operators (MNOs) and network infrastructure vendors towards the adoption of innovative solutions in areas that span from physical layer ...
Due to the rapid growth of mobile data traffic, future mobile networks are expected to support at least 1000 times more capacity than 4G systems. This trend leads to an increasing energy demand from mobile networks which ...
Data traffic has emerged as a big challenge for the standardization of traffic management mechanisms in ATM networks. In April 1996 the ATM Forum published the first version of the Available Bit Rate Service Category (ABR) ...
The rise of third-party content providers and the introduction of numerous applications has been driving the growth of mobile data traffic in the past few years. In order to tackle this challenge, Mobile Network Operators ...
The growth in air traffic has led to a continuously growing environmental sensitivity in aviation, encouraging the research into methods for achieving a greener air transportation. In this context, continuous descent ...
This research aims to improve engineering education in sustainability (EESD) through transdisciplinarity (td) learning approaches. The research comprised 3 phases. The first consisted of the analysis of how sustainability ...
La evaluación preliminar de los resultados de la Reforma Ferroviaria Europea muestra la lentitud de su implementación y la existencia de insuficiencias en el nivel de competencia introducido en el mercado y en la consecución ...
The knowledge transfer in traditional enterprises has been deeply studied, although there are no articles to be treated within the university spin-off companies, which often operate in dynamic environments. In this paper ...
Human-machine interaction in teleoperation, through the adequate user interface, allows achieving the level of intelligence necessary to execute complex tasks that cannot be executed by machines or robots alone neither ...
La tesis presenta un modelo no recursivo de sistemas no lineales (SNLS) basado en las series de fourier, estableciendo una comparación con el modelo de volterra en términos de coste computacional y diseño. <br/><br/>Del ...
In the present thesis a theoretical and empirical study of the relationship between transformational leadership (TL) styles and organizational commitment (OC) is performed. These two concepts are examined as multidimensional ...
This Thesis studies different cellular and cell population processes driven by non-linear and stochastic dynamics. The problems addressed here gravitate around the concepts of transient dynamics and relaxation from a ...
The atmospheric boundary layer is the part of the troposphere influenced by the presence of the surface, and where most weather phenomena occur. During the day, with fair weather conditions, a convective boundary layer ...
Several clinical studies for non-invasive estimation of tissue hemodynamics by the combination of two diffuse optical techniques, time-resolved and diffuse correlation spectroscopy, were carried out in collaboration with ...
