(Date of defense: 12-12-2016)Sprayed concrete is widely used as structural support for the stabilization of tunnel walls and underground constructions. The performance of sprayed cementitious matrices containing accelerators is strongly related to ...
-
(Date of defense: 17-10-2016)During the oil recovery a hole is drilled, the sandstone is left unsupported next to the cavity and disloged sand grains can enter the oil recovery system. This process is called sand production and several problems may ...
-
(Date of defense: 15-12-2017)This thesis investigates numerical methods that approximate the solution of compressible flow equations. The first part of the thesis is committed to studying the Variational Multi-Scale (VMS) finite element approximation ...
-
(Date of defense: 09-06-2017)Under severe seismic excitation, structural behavior of buildings and other constructions is highly complex. It involves, among other issues, soil-structure interaction, large strains and displacements, damage, plasticity, ...
-
(Date of defense: 02-09-2019)Simulation Based Engineering Science (SBES) has brought major improvements in optimization, control and inverse analysis, all leading to a deeper understanding in many processes occuring in the real world. These noticeable ...
-
(Date of defense: 30-01-2019)Marine mammals face numerous anthropogenic threats, including fisheries interactions, ocean noise, ship strikes, and marine debris. Monitoring the negative impact on marine mammals through the assessment of population ...
-
(Date of defense: 16-05-2019)Mineral masterbatches, in other words mineral fillers, are concentrates of calcium carbonate or talc in a polymer base. In addition to their optimal cost, their use improves mechanical properties of materials and reduce ...
-
(Date of defense: 20-01-2020)This thesis explores the potential of models based on the discrete element method (DEM) to study dynamic probing of granular materials, considering realistic particle-scale properties. The virtual calibration chamber ...
-
(Date of defense: 30-01-2017)The damage assessment of structures under seismic actions, must seek the implementation of new theories, tools and procedures that reduce the uncertainty associated to the expected structural response of a building. This ...
-
(Date of defense: 18-09-2017)The main objective of this thesis is the probabilistic assessment of the expected seismic damage in steel buildings located in Mexico City. Although a deterministic analysis is performed both, seismic actions and buildings, ...
-
(Date of defense: 07-03-2019)Coupled processes between the soil and the atmosphere control soil water evaporation in its first stage, which leads to soil shrinkage and cracking by drying. However, soil-atmosphere interaction has received little attention ...
-
(Date of defense: 11-01-2017)Au cours des dernières années, les analyses multi-échelles en mécanique des sols granulaires deviennent de plus en plus répandues. L’avantage de ce type d’approches réside dans leur capacité à établir un lien entre les ...
-
(Date of defense: 23-11-2017)Collision between adjoining buildings is relevant, since the huge impact forces significantly modify the buildings dynamic behaviour. The separation required by the regulations avoids pounding; however, even in recent ...
-
(Date of defense: 23-06-2017)The response of the climate systems to aerosols and their effect on the radiative budget of the Earth is the most uncertain climate feedback and one of the key topics in climate change mitigation. Air quality-climate studies ...
-
(Date of defense: 19-09-2019)Increasing amounts of organic synthetic chemicals are currently emitted to the environment by human activities. The more recalcitrant fraction of this pollutant mixture reaches marine ecosystems mainly through rivers, ...
-
(Date of defense: 13-09-2018)The water currents and the wave field at the Catalan coast (in the Northwestern Mediterranean Sea) are investigated. However, the main research is focused at the northern margin of the Ebro Shelf, where there is a relatively ...
-
(Date of defense: 11-10-2018)Materiales arcillosos rígidos, que se encuentran en la zona de transición entre suelos duros y rocas blandas, están siendo considerados actualmente en varios países como la roca huésped para el almacenamiento geológico ...
-
(Date of defense: 08-03-2019)The conceptualisation of a groundwater system involves continuous monitoring and evaluation of a large number of parameters (e.g., hydraulic parameters). Regarding hydraulic properties of the aquifers, their quantification ...
-
(Date of defense: 20-11-2017)Water is essential for life, human activities and ecosystems. The global climate change together the population increase causes an imbalance between the demand of water and the available water resources.. All these factors ...
-
(Date of defense: 31-07-2018)The construction and conservation of road networks represent a major part of public expenditure. For instance, the EU-28 countries annually spend approximately EUR 20.000 million on roadway preservation. These figures ...
