Large scale computing infrastructures need scalable and effi cient resource allocation mechanisms to ful l the requirements of its participants and applications while the whole system is regulated to work e ciently. ...
In this dissertation, I propose a theoretical model to rate enterprises in the context of social, solidarity or popular economics . The model defines a model of three dimensions to classify these organizations, going from ...
Firstly, I reviewed modelling approaches that were used to assess the impact of invasive alien species (IAS) in aquatic ecosystems. According to the review, multispecies/ecosystem mechanistic models dominated the applications, ...
Environmental impacts associated to the unstoppable growth of human population are threatening ecosystems worldwide. Among them, soil ecosystems are becoming increasingly degraded due to their unsustainable use and management, ...
More than one-third of Earths available freshwater is used for anthropogenic purposes, which has led to its contamination by numerous chemical compounds. Their presence in the environment might have negative consequences ...
It is well known the important role that difference equations play in several problems of the engineering or of the science. However, whereas the expression of the solutions when the coefficients of the equations are ...
This thesis focuses on how to optimize the placement of the Edge Computing infrastructure for upcoming 5G networks. To this aim, the core contributions of this research are twofold: 1) a novel heuristic called Hybrid ...
Electromagnetic methods (EM) are an invaluable research tool in geophysics whose relevance has increased rapidly in recent years due to its wide industrial adoption. In particular, the forward modelling of three-dimensional ...
The construction of each building appears with respect to the space between others. These volumes give way to future edifications. Each proposal participates in the inexhaustible character of the urban complex that surrounds ...
Increased wildfire activity over the last years has made fire managers to become more concerned about the effectiveness of current fuel treatment practices to reduce fire risk and severity. Fuel treatments lead to changes ...
El amonio es el catabolito mayoritario en los peces, significando más del 60% de los residuos nitrogenados totales, y siendo la fracción no ionizada (ANI) un compuesto tóxico tanto para el medio de cultivo como para el ...
El aluminio y sus aleaciones son las matrices metálicas más utilizadas para la fabricación de materiales compuestos, debido a su baja densidad, capacidad de endurecimiento por precipitación, buena resistencia a la corrosión ...
La gestió dels residus radioactius d'alta activitat suposen un dels majors reptes tecnològics de la societat actual, considerant-se la disposició en un Magatzem Geològic Profund (MGP) com la única alternativa viable per a ...
The use of bituminous material milled from the pavement (known as Reclaimed Asphalt Pavement, or RAP) in the manufacture of recycled bituminous mixtures is growing day by day due to the economic and environmental benefits ...
El presente trabajo de investigación se enfoca en el estudio del comportamiento a fluencia y ductilidad en caliente de los denominados aceros de construcción y su dependencia con la composición química, concretamente el ...
El agrietamiento transversal en la superficie de los productos de colada continua es un problema que sigue provocando el rechazo de algunos de estos productos con las correspondientes pérdidas energéticas y económicas. A ...
The problem of academic achievement on the basic concepts of mechanical physics in the preparatory course of Introduction to Physics, and attitude of students to the course are the triggers for this study, on the development ...
El tema de investigación de la tesis doctoral surge como consecuencia de una sucesión de investigaciones anteriores, en las cuales se ha construido y utilizado un concepto denominado “probabilidad funcional”, para explicar ...
Asphalt mixtures cracking is one of the most common deterioration mechanisms in flexible pavements. This phenomenon is due to both the application of loads and the degradation of the material as a result of its exposure ...
(English) This thesis is focused on analysing the impact produced by washwater discharges from exhaust gas cleaning systems fitted on ships on the pH level of Barcelona port waters. These systems are being used on board ...
