Esta Tesis presenta los resultados de la investigación desarrollada en el marco del proyecto Temperature Buffer Test (TBT). El objetivo general de este proyecto es investigar el desempeño de la bentonita usada en barreras ...
El análisis de problemas Termo-Hidro-Mecánicos (THM) en medios de baja permeabilidad es un problema complejo en el cual confluyen diversos factores. Esta Tesis está orientada principalmente al estudio de procesos THM ...
Los procesos termo-hidro-mecánicos relacionados con el almacenamiento geológico de carbono deben ser entendidos y cuantificados para demostrar a la opinión pública de que la inyección de dióxido de carbono (CO2) es segura. ...
This thesis deals with the numerical simulation of welding processes. The analysis is focused either at global level, considering the full component to be jointed, or locally, studying more in detail the heat affected zone ...
In the last decades, optics has become central in many applications in modern society. Nano-optics, which studies the behavior of light at the nanoscale, holds promise to do the same. However, when using traditional optical ...
Thermodynamics traditionally deals with macroscopic systems at thermal equilibrium. However, since the very beginning of the theory, its range of applicability has only increased, nowadays being applied to virtually every ...
Natural disasters, such as landslides triggered by heavy rains, rock deformations and soil cracking in presence of temperature changes and other phenomena related to climatic actions, show the relevance of investigating ...
(English) The thesis is mainly divided into two parts. In essence, the first one is an extension of the paper [Ter22]. Using the regularized Siege-Weil formula of [GQT14] we obtain an explicit expression for the truncated ...
The first goal of this Thesis is to contribute to the study of principally polarized abelian varieties (ppav), especially to the Schottky and the Torelli problems. Ppav admit a duality theory analogous to that of projective ...
Argillaceous rocks (Stiff sedimentary clays) provide the geological background to many civil engineering projects. In recent years, interest in these types of material has increased, because they are being considered as ...
(English) Deep geological disposal of heat-emitting and long-lived radioactive waste is the solution internationally accepted that offers the most viable and safest way to manage this kind of wastes. Accordingly, the ...
The earliest buildings designad by Thomas Herzog reflect practicas of solar design. Overarching geometric forms as well as efficient structures complimented long, slanted south-facing walls incorporated in the meticulously-crafted ...
Hoy en día, los sistemas de imagen basados en cámaras CCD son ampliamente utilizados en numerosos campos, en particular, en el campo de la imagen científica debido a su alta resolución, alta eficiencia cuántica, amplia ...
Firstly, an External Model Deformation Decomposition based Persistent Scatters Interferometry (EMDD-PSI) method has been proposed. This method first uses original interferograms to optimize the parameters of the external ...
This research project focuses on the analysis and prediction of flow structures and sediment transport process in open channels by using three-dimensional numerical models. The numerical study was performed using the ...
This thesis aims at unifying two distinct branches of work within the Heat Transfer Technological Center (CTTC). On one side, extensive experimental work has been done during the past years by the researchers of the ...
Traditionally, the sea has been considered as the ultimate sink of most pollutions, due to its huge volume and assimilating capacities, and the coastal waters, because of their intermediate position between deep seas and ...
(English) Classical and Recurrent novae are thermonuclear explosions hosted by accreting white dwarfs in stellar binary systems. Material piles up on top of the white dwarf star under mildly degenerate conditions, driving ...
We consider some models of random graphs and directed graphs and investigate their behavior near thresholds for the appearance of certain types of connected components. Firstly, we look at the critical window for the ...
This thesis emanates from the premise that the impact of an architectural project is manifested not only in the organization of space and, by extension, in the social relationships established therein, but mainly in the ...
