Microwave radiometry field has been increasing its performance with higher accuracy measurements, leading to a more presence in the remote sensing field. Several space-borne, air-borne and ground-based radiometers have ...
The thesis focuses on the provision of cellular vehicle-to-everything (V2X) communications, which have attracted great interest for 5G due to the potential of improving traffic safety and enabling new services related to ...
The new era of mobile communications is dictated by the user demand for robust and high speed connections, data hungry applications and seamless connectivity. Operators and researchers all over the world are challenged to ...
As numerous mobile applications and over-the-top (OTT) services emerge and mobile Internet connectivity becomes ubiquitous, the provision of high quality of service (QoS) is more challenging for mobile network operators ...
The number of transistors on an integrated circuit keeps doubling every two years. This increasing number of transistors is used to integrate more processing cores on the same chip. However, due to power density and ILP ...
(English) The exquisite control available in atomic ultracold quantum gases experiments makes them an ideal candidate for quantum simulation of diverse topics ranging from high energy physics and analogue quantum gravity ...
En aquesta tesi s'estudien diferents problemes en el camp de la combinatòria i la teoria de grafs, utilitzant el mètode probabilístic. Aquesta tècnica, introduïda per Erdős , ha esdevingut una eina molt potent per tal de ...
Solutions to high-dimensional parameter-dependent problems are in great demand in the contemporary applied science and engineering. The standard approximation methods for parametric equations can require computational ...
En la última década, la cooperación entre usuarios ha generado un gran interés por la posibilidad de mejorar la velocidad de transmisión en las redes de comunicaciones inalámbricas. El objetivo es formar un array con las ...
Nowadays, rare earth elements (REEs) have gained importance due to their indispensable and critical use in many high-tech industries like hybrid cars, fluorescent lamps, flat screen televisions, mobile phones, disc drives ...
This thesis explores one of the essential arithmetical and diophantine properties of Shimura curves and their Atkin-Lehner quotients: the existence of rational points on these families of curves over both number fields and ...
(English) Cancer is the second leading cause of death globally, only behind cardiovascular diseases, being a major public health issue. Cancer comprises a wide group of diseases characterized by abnormal cell growth, which ...
A significant part of the pathologies found in concrete dams is related with the presence of unsound aggregates that react with the cement paste. Such reactions may lead to expansions, causing damage and compromising the ...
El problema en el presente trabajo ha sido abordado desde distintos ángulos. En primer lugar con relación a la repercusión de la construcción masiva de viviendas en la expansión de la ciudad y en el elevado consumo energético. ...
Artificial recharge of aquifers through infiltration basins (AR) improves water quality and in- creases groundwater resources, which make of it an appropriate technique for the renaturalization of waters affected directly ...
En general, el control de procesos es muy eficiente cuando el punto de operación deseado ha sido determinado a priori y el sistema tiene capacidad suficiente para responder a las perturbaciones. Mientras el control de ...
Nowadays, optical access networks provide high capacity to end users with growing availability of multimedia contents that can be streamed to fixed or mobile devices. In this regard, one of the most flexible and low-cost ...
The real-time control systems industry is moving towards the consolidation of multiple computing systems into fewer and more powerful ones, aiming for a reduction in size, weight, and power. The increasing demand for higher ...
Several socioeconomic factors are leading governments to encourage electric powered vehicles. Currently, the bottleneck for electric vehicles mass production lies in the high voltage battery technology. One of the main ...
This thesis concerns the specific field of visualization of medical models using commodity and mobile devices. Mechanisms for medical imaging acquisition such as MRI, CT, and micro-CT scanners are continuously evolving, ...
