Bentonite-based materials are being currently considered in several countries as a backfill component in the multi-barrier concept for deep geological disposal of radioactive waste. The bentonite barrier fulfils several ...
This research focusses on an experimental investigation on the hydro-mechanical behaviour of binary ‘all-one’ mixtures. These mixtures –originated from the excavation of selected materials during earthwork constructions– ...
The hydro-mechanical behaviour of MX80 bentonite pellet-based mixture (80% high-density pellets in dry mass and crushed granular powder) has been explored in this thesis within the context of the French ‘Vertical Sealing ...
El propòsit del treball es caracteritzar hidrodinàmicament els tancs més utilitzats en el sector aqüícola, i donar pautes de disseny per millorar-ne l'autoneteja, i optimitzar l'eficiència d'utilització tant de l'espai com ...
(English) Hydrodynamic models are essential for our understanding of the physics of stellar explosions, and specifically, for their potential contribution to the Galactic chemical abundances. In this Work, a one-dimensional ...
Using both observations and modelling tools, it is investigated the main hydrodynamic response mechanisms of a microtidal and shallow bay in the Mediterranean Sea: Alfacs Bay. Main objectives are considered using differenttim ...
The characterization of evaporitic aquifers for a better understanding of hydrodynamics and geochemical processes is of great importance, especially in environments where both the sustainability of unique ecosystems and ...
Hydrogen constitutes a promising alternative to manage our energy supply more efficiently. Hydrogen can be stored and used in fuel cells to produce electricity, where it combines with the oxygen present in the air and ...
The competition for space in urban areas due to an exponential growth of population makes derground engineering plays a crucial role in the development of cities. Urban underground infrastructures deal with variables such ...
This thesis aims to advance the knowledge of the hydrogeological functioning of salt flats in order to achieve a sustainable management of their mineral resources and ecosystems. Salt flats are a major source of Li, B, I, ...
Development of new drug molecule is expensive and time consuming. Improving safety efficacy ratio of “old” drugs has been attempted using different methods such as individualizing drug therapy, dose titration, and therapeutic ...
The optimal exploitation of the information provided by hyperspectral images requires the development of advanced image processing tools. Therefore, under the title Hyperspectral image representation and Processing with ...
Vision loss affects physical, psychological, and emotional wellbeing and social life as well. High life expectancy and health policies are translated into an aging population worldwide, which has higher risk of eye’s ...
El presente trabajo de investigación se centra en la evaluación global de la calidad acústica de los espacios interiores públicos “no acústicos” mediante un índice numérico. En la sociedad contemporánea asistimos a menudo ...
Large cities and urban regions need to be addressed, given their size, in a different scale, from a global and regional approach. This overall look, which creates real "city projects", is the topic chosen as the subject ...
El control i supervisió de processos es basa generalment en la utilització de models. Models que han de ser tan acurats com sigui possible. Processos complexes com les xarxes de distribució d'aigua no escapen d'aquesta ...
Ports serve as a point of entry, exit and storage for wide variety of goods. In order to ensure safety, these activities are subject to strict national and international laws that stipulate the standard safety and operational ...
En esta tesis se desarrolla una metodología general para la identificación de parámetros en problemas geotécnicos. <br/><br/>Dado un problema especifico se supone fijado un modelo (determinista) y se consideran conocidos ...
This thesis addresses new business models that allow firms in emerging economies to be globally competitive through strategic innovations. lt also seeks far the strategic nucleus of these firms in these economies to reflect ...
The work underlying this Thesis, has contributed to the main study and characterization of diffusive systems. The research work has been focused on the analysis of two kind of systems. On the one hand, the dynamics of ...
