The ever-increasing growth of the wireless application and services affirms the importance of the effective usage of the limited radio spectrum. Existing spectrum management policies have led to significant spectrum ...
The last decades, we have witnessed different phenomenology in the telecommunications sector. One of them is the widespread use of the Internet, which has brought a sharp increase in traffic, forcing suppliers to continuously ...
Network interference of nearby jobs has been recently identified as the dominant reason for the high performance variability of parallel applications running on High Performance Computing (HPC) systems. Typically, HPC ...
his dissertation proposes novel techniques for assigning resources of wireless networks by considering that the coverage radii are small, implying that some power consumption sinks not considered so far shouldnow be ...
This thesis is a result of contributions to optimize or improve resource allocation in Passive Optical Networks (PON). The contributions are related with resource allocation during PON operation and with the upgrade process ...
Upon the demanding requirements brought by next-generation services, current network infrastructures are required to evolve in the way they manage different types of resources at the data layer. To this end, a set of novel ...
(English) As one of our most successful theories, quantum theory has greatly strengthened our understanding of nature and significantly advanced technologies. Specifically, quantum effects provide advantages in a broad ...
Distributed Real-Time Media Processing refers to classes of highly distributed, delay no-tolerant applications that account for the majority of the data traffic generated in the world today. Real-Time audio/video conferencing ...
Innovation is an essential activity for the competitiveness of firms. It has also contributed positively to increasing the living standards of millions of people. However, it is widely recognized that innovation co-produces ...
The study of the elastic, dielectric and piezoelectric non-linear behavior in PZT-based and KNN-based piezoelectric ceramics represent the main goal of this work. Both systems present a perovskite-like structure. Several ...
In recent years hard coatings have acquired a significant importance in the microstructural and micromechanical design of forming tools. Among the wide range of surface modification techniques, physical and chemical vapour ...
Las estrategias de ahorro de energía en edificios, posibilitan la disminución de los costos de operación y/o mantenimiento de los mismos a lo largo de su vida útil. Sin embargo, el confort térmico de los usuarios se ve en ...
European sea bass (Dicentrarchus labrax) aquaculture is a thriving industry in Spain where it reached about 23,500 t and a market value of approximately 133 million euros. However, most of the sea bass farms produce a high ...

La Educación Superior constituye un imperativo estratégico para los países, impactando a la sociedad como un todo, siendo la formación de capital humano avanzado uno de los factores que permite un mayor bienestar de las ...
The upper ocean circulation is the area of confluence of two major vertical cells: the large-scale overturning Atlantic Meridional Overturning Circulation (AMOC) and the regional relatively shallow Subtropical Cells (STCs). ...
(English) Marine heterotrophic flagellates (HF) are very small (2-5 µm) unpigmented protists that are dominant bacterial grazers in the ocean, where they link the transfer of carbon from bacterial cells to higher trophic ...
Modern processors use out-of-order processing logic to achieve high performance in Instructions Per Cycle (IPC) but this logic has a serious impact on the achievable frequency. In order to get better performance out of ...
The aluminum alloy AA2024-T3, u sed extensively in the aerospace industry, dueto the heterogeneous microstructures intentionally designed to optím ize the m echanical properties, is very susceptible to localízed corros ...
(English) This thesis presents the Tychonis framework, a solution to the limitations faced by existing software packages used in space missions to identify geometric events. The framework is designed to integrate with ...
