Badia Rodriguez, Hugo (Date of defense: 2016-12-19)
This thesis discusses which transit network structure is the best option to serve urban mobility. As a consequence of the evolution of urban form, cities have undergone a dispersion process of their activities. This fact ...
Lanko, Iryna (Date of defense: 2022-01-27)
Anaerobic digestion (AD) is currently spread all over the world for sewage sludge stabilisation, volume reduction and green energy production. Its implementation contributes to turn a wastewater treatment plant (WWTP) into ...
Tsiolakis, Vasileios (Date of defense: 2020-01-31)
The present thesis explores the viability of the proper generalised decomposition (PGD) as a tool for parametric studies in a daily industrial environment. Starting from the equations modelling incompressible flows, the ...
Weber, Rodrigo Carreira (Date of defense: 2019-12-13)
This thesis analyzes the hydro-mechanical behavior under a generalized stress state of a compacted mixture of sand (30%) and clayey (70%) at a low density. The experimental study focuses on the analysis of shear strength ...
Alvarado de Menéndez, Clara Elena (Date of defense: 2017-05-18)
Rockfill is a coarse material widely used in geotechnical works such as earth-fill dams (shoulders and toe drains), as well as in embankments and well-graded quarry materials for railway infrastructures. These structures ...
Lu, Xufei (Date of defense: 2022-07-15)
The objectives of this thesis are (i) to understand the thermal, metallurgical and mechanical behavior during AM, (ii) to shed light on the generation of residual stresses and the stress-induced deformations and cracks, ...
Petracca, Massimo (Date of defense: 2016-04-13)
Masonry is an ancient building material that has been used throughout the history, and it is still used nowadays. Masonry constitutes the main building technique adopted in historical constructions, and a deep understanding ...
Caicedo Silva, Manuel Alejandro (Date of defense: 2017-02-24)
This thesis focuses on the numerical modeling of fracture and its propagation in heterogeneous materials by means of hierarchical multiscale models based on the FE2 method, addressing at the same time, the problem of the ...
Garikapati, Hasini (Date of defense: 2020-03-28)
Uncertainty quantification is important in assessing and predicting the performance of complex engineering systems and processes, especially in the absence of adequate experimental or real-world data. With the increase ...
Belda Ferrín, Guillem (Date of defense: 2022-10-28)
[English] In n-dimensional adaptive applications, conformal simplicial meshes must be lo cally modified. One systematic local modification is to bisect the prescribed simplices while surrounding simplices are bisected ...
Cruz Romero, Janill Marie de la (Date of defense: 2020-07-27)
The use of the fibre reinforced concrete (FRC) as a construction material has expanded beyond the traditional applications since the publication of design codes and structural guidelines. Fibre reinforced concrete for ...
Corbella Vidal, Clara (Date of defense: 2017-11-10)
Horizontal Subsurface Flow Constructed Wetlands (HSSF CWs) are natural wastewater treatment systems showing a marked redox gradient between the surface of the system and the bottom zone of the treatment bed. Therefore, ...
Flores Rosell, Laura (Date of defense: 2021-10-01)
The wine industry generates large volumes of wastewater originating from various processes and operations carried out during wine production. Winery wastewater (WWW) is characterized by highly variable flows and loadings. ...
Hartl, Marco (Date of defense: 2020-07-03)
The objective of this work was the improvement and control of wastewater treatment using constructed wetlands operated as Microbial Fuel Cells (CW-MFCs) and Microbial Electrolysis Cells (CW-MECs). For this purpose, eight ...
Madrid Argomedo, Manuel Ricardo (Date of defense: 2021-07-21)
The design and construction of vertical caisson breakwaters on soft soils represents a significant challenge for the engineering of marine structures. Past experience reveals that this type of structures is sometimes prone ...
Aznar Alemany, Òscar (Date of defense: 2017-11-20)
During the last couple of decades the demand for good quality water in sufficient quantity has increased. The administration is now aware that water is not a commercial product; that hydrological management needs to be ...
Martín Cañizares, María del Pilar (Date of defense: 2015-11-16)
Building a high-speed line requires significant investment and its design strongly influences the operation, with the aggravating circumstance that subsequent modifications not initially planned are not always feasible at ...
Tejedor Herrán, Blanca (Date of defense: 2019-01-24)
Within the European framework, most of residential buildings do not satisfy the minimum thermal specifications. In fact, the renovation rate across the EU is estimated at 1% per year. To fulfil with the goals stated by ...
Lomelí Quintero, Víctor Manuel (Date of defense: 2023-10-13)
(English) Climate change is a major issue that is having a significant impact on coastal areas globally. This phenomenon is generating processes of erosion, flooding and sea level rise, which is of great concern. These ...
Maso Sotomayor, Miguel (Date of defense: 2022-09-29)
(English) This thesis investigates numerical methods for the simulation of surface water flows, focusing on the interaction between the large scale and the local scale and its application to natural hazards. Several families ...
