In the last decades, polymeric biomaterials, due to their advanced physical and mechanical properties, have been used in a vast variety of surgical and pharmaceutical applications. In this thesis, a study on crystallinity, ...
Reinforced concrete members, especially when subjected to concentrated loads, can fail in shear. This is an undesirable and brittle failure mode preventing the structure from deforming and reaching higher load levels. It ...
Network virtualization is recognized as an enabling technology for the future Internet. It aims to overcome the resistance of the current Internet to architectural change and to enable a new business model decoupling the ...
Se establece la metodología, incluyendo la formulación necesaria, para el diseño térmico de subenfriadores criogénicos n2(i)-n2(i), observando en todo momento criterios de optimización para con los diferentes parámetros y ...
The aim of this thesis is to study the hyperinvariant and characteristic subspaces of a matrix, or equivalently, of an endomorphism of a finite dimensional vector space. We restrict ourselves to the case of matrices A with ...
La descripción del flujo de fluidos involucra la solución de las ecuaciones de Navier-Stokes compresible, un problema muy complejo cuya estructura matemática no es del todo comprendida. Por lo tanto, mediante análisis ...
La figura de Subirana ha ido siempre ligada al trio de Arquitectos que formó con Sert y Torres Clavé dentro del GATCPAC. Su nombre ha quedado ligado a obras tan importantes como el conjunto residencial de la Casa Bloc, al ...
El camp d'Experiència d'Usuari consta d'una àmplia gamma d'aspectes diferents sobre la interacció amb productes o serveis. L'experiència d'usuari difereix del paradigma objectiu basat en el rendiment, centrant-se en un ...
Experimental study was conducted to analyze the physical flow turbulence and sediment distribution with submerged vane. The objectives behind the investigation were verified and compare results with the Odgaard theory, ...
This dissertation deals with different subset selection problems in wireless communications systems. These type of problems have a combinatorial nature, which makes them computationally intractable for medium and large-scale ...
This thesis focused on the feasibility of substituting, partially or totally, drinking water treatment plant (DWTP) conventional pre-treatment by membrane based units, in particular by ultrafiltration (UF). For such purpose, ...
Infiltration systems are water treatment technologies where water vertically percolates through porous media while several biogeochemical processes occur. Biofilms are the main responsible for those biogeochemical processes ...
This research deals with rural land treatment in the urban planning of three metropolitan regions of southern Europe from the beginning of the twentieth century to the present day, focusing on how it has contributed to ...
The main motivation of this thesis is the analysis of turbulent flows. Turbulence plays an important role in engineering applications due to the fact that most flows in industrial equipment and surroundings are in turbulent ...
The overall aim of the thesis is to encourage the presence of sunlight into indoor spaces. The specific objective is to show that, from the lighting point of view, a good design can harness the solar reflection on the ...
Es cada día más frecuente la representación de superficies mediante modelos de alambre utilizando ordenador. Una de las dificultades que presentan estos modelos es la obtención de las coordenadas de los puntos de la malla, ...
Tourist attractions are an essential part of urban tourism. It is often thought that attractions are comparable to each other and that their impacts can be limited as if cities could manage their tourist flows as theme ...
La presente tesis estudia el uso que realizan los habitantes de los colectivos minoritarios en los espacios públicos del casco antiguo de Barcelona identificando las principales transformaciones de tipo funcional, significados, ...
The resolution of a conventional fluorescence microscope image is diffraction limited which achieves a spatial resolution of 200nm lateral and 500nm axial. Recently, many superresolution fluorescence microscopy techniques ...
En la darrera dècada, el disseny de sistemes de supervisió per a processos industrials ha rebut força atenció. Aquest fet s'explica per l'augment de la demanda en prestacions, flexibilitat i seguretat causada per la creixent ...
