Las tendencias del mercado han hecho que las empresas cambien su forma de hacer negocios. La Globalización ha permitido a las empresas tener la posibilidad de acceder a distintos proveedores y mercados globalmente dispersos. ...
Conventional lock-based synchronization serializes accesses to critical sections guarded by the same lock. Using multiple locks brings the possibility of a deadlock or a livelock in the program, making parallel programming ...
There are several LPWAN radio technologies providing wireless communication to the billions of connected devices that form the so-called IoT. Among them, LoRa has emerged in recent years as a popular solution for low power ...
In this thesis we study feature subset selection and feature weighting algorithms. Our aim is to make their output more stable and more useful when used to train a classifier. We begin by defining the concept of stability ...
Context: Globalization, increased competition for natural resources, the rise of non-financial performance indicators in decision making, among other new trends have made sustainability more and more relevant and linked ...
Current Supply chain (Se) decision support tools are devoted to the optimization of one objective function from a bias centralized perspective, without considering the coexistence with other participants and their uncertain ...
Programmable Graphics Processing Units (GPUs) have recently become the most pervasitheve massively parallel processors. They have come a long way, from fixed function ASICs designed to accelerate graphics tasks to a ...
(English) This thesis aims to investigate the efficacy and applicability of Wireless Backhaul Network (WBN) in two divergent contexts: ultra-dense urban networks for 5G and connectivity solutions for rural or digitally ...
Current large scale systems show increasing power demands, to the point that it has become a huge strain on facilities and budgets. The increasing restrictions in terms of power consumption of High Performance Computing ...
Recent developments of high performance computing capabilities allow solving modern science problems employing sophisticated computational techniques. However, it is necessary to ensure the efficiency of state of the art ...
(English) The study of the colonic volume has strong relevance in gastroenterology and contributes to the diagnosis and research of lowseverity diseases such as constipation, diarrhea, or Irritable Bowel Syndrome. In the ...
Attosecond science investigates the realm of processes that happen in fleetingly short passages of time. One attosecond to one second, is what one second is to the age of the universe! Advances in lasers and specifically ...
The rare earth elements (REEs) are essential ingredients for the development of modern industry and the transition to a more sustainable economy model. The unique physicochemical features of these elements, such as their ...
This thesis develops a numerical tool (the Virtual Wind Tunnel, VWT) for the resolution of problems involving fluid flow around structures. Due to the limitations that traditional methods may have in this context, the VWT ...
Most of the urban wastewater treatment plants (WWTP), based on conventional activated sludge (CAS) systems, cannot be considered sustainable since the concept of resources (energy and nutrients) recovery is not taken into ...
This thesis aims at contributing to overcome two of the main challenges for the deployment of M2M networks in data collection scenarios for the Internet of Things: the management of massive numbers of end-devices that ...
Field biomonitoring based on molecular biomarkers detects early warning signals of stress suffered by organisms exposed to contamination. The lower part of the Ebro River basin has a long pollution history related to the ...
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 ...
