Parallel programming is used to partition a computational problem among multiple processing units and to define how they interact (communicate and synchronize) in order to guarantee the correct result. The performance that ...
Persistent high levels of NO2 have severe health effects on population. These are often found in large urban conurbations with high vehicle densities. In Barcelona, with one of the highest vehicle densities in Europe, the ...
Since the emergence of Lean Manufacturing, many organizations strived to implement it. Nonetheless, sustainable Lean transformation is not as easy as to be simply achieved. Severa!aspects need to be taken into account ...
(English) The 20th-century introduction of the Haber-Bosch nitrogen fixation process significantly disrupted the nitrogen cycle in ecosystems, contributing to environmental issues and nutrient loss. The heavy reliance on ...
Phosphate and ammonium removal from waste water by adsorption using inorganic natural sorbents has been identified as a promising technology. The advantages of this methodology are associated with its availability and ...
It is questionable whether DRAM will continue to scale and will meet the needs of next-generation systems. Therefore, significant effort is invested in research and development of novel memory technologies. One of the ...
The combined use of thermal-hydraulics system with sub-channel codes (TH-TH coupling) in transient analysis provides an integrated tool with the capability of modelling in detail both the core thermal-hydraulic conditions ...
In recent decades, the use of High Performance Concrete (HPC) has grown vastly, being used in multiple applications with high requirements. However, the use of recycled aggregates (RA) has been mostly limited to conventional ...
(English) The Future Circular Hadron Collider (FCC-hh) is a proposal for a 100-kilometre-long particle accelerator with collision energy substantially higher than previous colliders to expand the Large Hadron Collider (LHC) ...
(English) Event-based cameras are novel sensors with a bio-inspired design that exhibit a high dynamic range and extremely low latency. They sensing principle is different than the one of conventional cameras. These novel ...
In the wake of the great economic crisis of 1973, the migratory movement undergone through the previous twenty years in the metropolitan area of Barcelona comes to an end and urban growth slows down heavily. The end of ...
The thesis that is presented turned up from a shaping work with the original models of the second version of the naves, designed by Gaudi for the Temple of the Sagrada Familia, and that were destroyed during the civil ...
Las transformaciones que se han venido produciendo en el sistema productivo, a lo largo de los últimos cincuenta años en España, con la pérdida de peso de la actividad propiamente manufacturera en beneficio de los servicios, ...
El tema de esta investigación surgió al observar la "irrupción" que, durante el siglo XX, presentó el hormigón armado en la restauración de edificios históricos. A partir de los años cincuenta se generalizó el uso de esta ...
The development and population prosperity in the transition zone between the Sahara desert in the north and the tropical humid savannah in the south, known as Sahel, depends to a great extent on the rainfall regime. The ...
Manabí es la tercera provincia del país, por el número de población y la cantidad de rentas que aporta, sólo superada por Pichincha y Guayas. (...) En materia de arquitectura viviendística ha desarrollado muestras de ...
In this thesis we develop a multi-scale model of the evolutionary dynamics of a population of cells, which accounts for the mapping between genotype and phenotype as determined by a model of the gene regulatory network. ...
One of the main purposes of National Statistical Agencies (NSAs) is to provide citizens or researchers with a large amount of trustful and high quality statistical information. NSAs must guarantee that no confidential ...
Cuando se ha de compartir un recurso entre demandas (de productos, clientes, tareas, etc.) competitivas que requieren una atención regular, es importante programar el derecho al acceso del recurso de alguna forma justa de ...
Turbulence is one of the major concerns for most technological problems involving fluid motion. Specially in aeronautics, a turbulent boundary layer results in structural stresses, vibrations and higher aircraft drag, ...
