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 ...
The natural environment in which we live, is subjected, to a greater or lesser extent, to the pressure of human activity, with water being one of the most sensitive elements. For this reason, aware of this situation, from ...
Crowdsourcing, the art of involving several individuals in the decentralized execution of business activities, is being positioned as the replacement of outsourcing, as it allows organization to reach a capable workforce ...
Current software community players like academy and industry have been changing the traditional paradigms of software engineering towards context-awareness and distributed computing. Nowadays, service-oriented computing ...
Traumatic brain injury (TBI) is a leading cause of disability worldwide. It is the most common cause of death and disability during the first three decades of life and accounts for more productive years of life lost than ...
Dynamical instabilities which lead to spontaneous pattern formation are present in a wide variety of nonlinear dynamical systems, both in nature as well as in technological areas. The instabilities may be saturating, leading ...
Tetragonal polycrystalline zirconia doped with 3 mol% yttria (3Y-TZP) has become one of the most popular dental ceramics. Thanks to its outstanding mechanical properties (including high hardness. Toughness and wear ...
This thesis deals with the surface modification of cellulosic substrates by use of chemo-enzymatic methods. Functionalizing cellulose is intended to adjust its properties for various purposes, but particularly for obtaining ...
Debido a sus excelentes propiedades mecánicas y una excelente biocompatibilidad, el uso de las cerámicas de base de circona en aplicaciones dentales y ortopédicas ha crecido rápidamente durante las últimas décadas. Sin ...
