Cuadrado Cabello, Agustín (Data de defensa: 2019-03-07)
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 ...
Rivas Becerra, Daniel (Data de defensa: 2017-11-20)
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 ...
López Carreño, Rubén-Daniel (Data de defensa: 2018-07-31)
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 ...
Emadi, Seyyedbehrad (Data de defensa: 2020-12-11)
According to Timoshenko’s beam theory, nodal rotations in beam-like structures are produced by bending and shear effects. On the one hand, bending rotations can be easily calculated by the Euler-Bernoulli stiffness matrix ...
Quintero Perez, Guillermo (Data de defensa: 2019-07-08)
For the production of representative noise maps, a large amount of information is necessary, which includes, among others, on-site measurements of environmental noise. Thus, for noise maps based on measurements, mobile ...
Villota Cadena, Angel Patricio (Data de defensa: 2020-07-09)
The objective of the doctoral thesis is to perform the numerical approximation of the transient convection-diffusion-reaction (CDR) vector equation in 2D with high order finite elements, quadratic, cubic and fourth order, ...
Ferrer Ramos, Núria (Data de defensa: 2019-07-18)
One of the main drivers of the current global change is the climate change characterized by increased number and increased length of drought periods. Another relevant driver that will imply greater pressure on natural ...
Vieira, Mylene de Melo (Data de defensa: 2018-10-19)
High performance steel fibre reinforced cementitious composites (HPSFRCCs) show enhanced structural performance and durability. The improved properties favour its use in agressive conditions (such as marine environment) ...
Obiso, Vincenzo (Data de defensa: 2018-03-07)
In this thesis an assessment of the parameterization of the Aerosol-Radiation Interaction (ARI) in online integrated meteorology-chemistry models has been conducted. The model estimates of ARI radiative effects are still ...
Sanz Lanzas, Claudia (Data de defensa: 2023-05-26)
(English) The circular economy is an emerging concept presented as a solution to counteract the damage caused by the linear economic scheme followed in the past decades. It is based on the principle of "closing the life ...
Santos Rodríguez, Cristian de (Data de defensa: 2015-12-10)
Nowadays, thanks to the increase of computers capability to solve huge and complex problems, and also thanks to the endless effort of the geotechnical community to define better and more sophisticated constitutive models, ...
Guerrero Sánchez, Queralt (Data de defensa: 2019-02-08)
This Thesis conducts the study of bedform development and dynamics in the inner shelf integrating observations at different spatial and temporal scales. An initial assumption is that different scales of sedimentary processes ...
Ubach de Fuentes, Pere-Andreu (Data de defensa: 2020-11-18)
A new thin shell finite element is presented. This new element doesn’ t have rotational degrees of freedom. Instead, in order to overcome the C1 continuity requirement across elements, the author resorts to enhance the ...
Martínez Varela, Alícia (Data de defensa: 2022-04-29)
Increasing quantities of organic pollutants (OP) are being released to the environment, posing a threat to Earth’s life system. In the marine environment, OP pollution caused by oil spill accidents receives a lot of academic ...
Pizarro Loaiza, Carlos Alexander (Data de defensa: 2021-09-30)
Energy for cooking is the most essential energy service for peasants in countries with tropical climates such as Colombia where a large number of families can only access to firewood as energy source. An alternative energy ...
Tilves Matheu, Uxue (Data de defensa: 2019-05-16)
Jellyfish are important components of marine ecosystems, being a key link between lower and higher trophic levels. Jellyfish blooms occur sporadically and unpredictably in coastal areas and often have important socio-economic ...
Acevedo Dudley, Melissa Judith (Data de defensa: 2016-10-24)
Over the last years, the sightings of the cubomedusa Carybdea marsupialis have increased in the Mediterranean Sea and this has been linked to an increase in its abundance. Consequently, this phD thesis addresses some ...
