Nowadays large part of the time needed to perform a numerical simulation is spent in preprocessing, especially in the geometry cleaning operations and mesh generation. Furthermore, these operations are not easy to automatize ...
The present thesis aims at the analysis of the fragmentation of rockfalls. The fragmentation is a complex phenomenon poorly understood with a lack of tools to reproduce it on rockfall simulators. The effect of fragmentation ...
Retail is changing as technology is growing. The traditional way of shopping has evolved thanks to mobile devices, and retailers are struggling to avoid customers’ attrition. Customers are immersed in a seamless omnichannel ...
The global environmental change affects rural communities in an unprecedented way and brings transformations in the livelihoods in rural households. Rural households have a growing vulnerability to climate and non-climate ...
This thesis aims to assess the effects of the complex mixture of organic pollutants on the Prochlorococcus photosynthetic capability, in field, and at sublethal level, in the multifactorial context of the global change. ...
The most widely accepted option for the long-term management of radioactive waste materials considers their disposal in deep underground facilities (examples are Finland, Belgium, France, Sweden, etc.). Such installations ...
In recent years transport policy at an European Level has been focused on reducing the share of road transportation and promote alternative transportation means in order to reduce road congestion and carbon footprint. One ...
La luz comprimida (squeezed light) es uno de los componentes importantes de los experimentos de memorias cuánticas. Un almacenamiento eficiente<br/>de la luz comprimida en una colectividad de átomos exige que la luz ...
High Performance Computing (HPC) systems have become widely used tools in many industry areas and research fields. Research to produce more powerful and efficient systems has grown in par with their popularity. As a ...
Los temas de investigación sobre multithreading han ganado mucho interés en la arquitectura de computadores con la aparición de procesadores multihilo y multinucleo. Los procesadores SMT (Simultaneous Multithreading) son ...
All major semiconductor companies are now shipping multi-cores. Phones, PCs, laptops, and mobile internet devices will all require software that can make effective use of these cores. Writing high-performance parallel ...
In the middle of the 2000s a fundamental change of course occurred in computer architecture because techniques such as frequency scaling and instruction level parallelism were providing rapidly diminishing returns. Since ...
Following Moore's Law, the number of transistors on chip has been increasing exponentially, which has led to the increasing complexity of modern processors. As a result, the efficient programming of such systems has become ...
(English) Although robotic platforms have been used for a wide range of purposes, recent advances in robot autonomy raise the opportunity of bringing them closer to humans. This implies that, under any circumstance, robots ...
Chemical plants and other industrial installations process and store hazardous materials, which represent a certain risk to people, equipment and the environment. Overpressure is one of the most common upsets in process ...
Distributed Generators (DGs) are sensible to voltage sags, so the protection devices must trip fast to disconnect the faulted part of the grid. The DG disconnection will not be desirable in the near future with a large ...
The potential capacity of fertilization of surface oceans by atmospheric deposition is of scientific interest. This is especially true in the oligotrophic Mediterranean Sea. Its surface waters are extremely poor in nutrients ...
Considerando la gran importancia que tuvo la Iglesia Católica en el proceso de configuración de los núcleos urbanos coloniales brasileños, lo que se propone en este trabajo es estudiar el papel de la Orden Religiosa de los ...
This research investigates the qualitative effects of foreign direct investments of the clothing industry in a developing country like Albania. The clothing industry is often regarded as the first step of industrialization ...
En aquesta tesi s'estudia el problema d'estimació cega de segon ordre en comunicacions digitals. En aquest camp, els símbols transmesos esdevenen paràmetres no desitjats (nuisance parameters) d'estadística no gaussiana que ...
