Advancement of methods for passive acoustic monitoring : a framework for the study of deep-diving cetacean

Solsona Berga, Alba (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 ...

Advances in life cycle assessment of plastics with mineral fillers in packaging applications

Civancik-Uslu, Didem (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 ...

Análisis estructural probabilista orientado a evaluación del daño sísmico con aplicaciones a tipologías constructivas empleadas en Costa Rica

Hidalgo Leiva, Diego (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 ...

Análisis estructural sísmico de edificios de acero : un enfoque probabilista

Díaz Alvarado, Sergio Alberto (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, ...

Análisis THM de la interacción suelo-atmósfera en suelos arcillosos sometidos a desecación

Cuadrado Cabello, Agustín (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 ...

Analyse multi-échelle de l'approche énergétique de la rupture des grains au sein de matériaux granulaires

Salami, Younes (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 ...

Analysis of seismic pounding of moderate-height RC buildings with aligned slabs

Kharazian, Alireza (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 ...

Analysis of the aerosol-radiation-cloud interactions through the use of regional climate/chemistry coupled models

Baró Esteban, Rocío (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 ...

Analysis of the ocean dynamics in a wind-jet region using high-resolution models

Ràfols Bundó, Laura (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 ...

Analysis of underground excavations in argillaceous hard soils : weak rocks

Mánica Malcom, Miguel Ángel (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 ...

An approach for hydrogeological data management, integration and analysis

Criollo Manjarrez, Rotman A. (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 ...

Aplicación de MALDI-TOF Imaging y HPLC-MS/MS al estudio de la degradación del polímero policaprolactonadiol en diferentes medios acuáticos

Rivas Becerra, Daniel (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 ...

Aportaciones al proyecto, construcción y reparación de pavimentos de hormigón

López Carreño, Rubén-Daniel (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 ...

Approach to acoustic mapping through continuous mobile monitoring

Quintero Perez, Guillermo (Date of defense: 08-07-2019)
