Cáceres León, Richard Humberto (Date of defense: 2018-11-08)
El propósito de esta investigación es maximizar el impacto de la asimilación de datos radar sobre el pronóstico de precipitación a muy corto plazo usando el modelo Weather Research and Forecasting (WRF), de tal manera que ...
Català i Castro, Frederic (Date of defense: 2018-12-18)
Mechanics is the branch of physics that studies movement and force, and plays an evident role in life. The swimming dynamics of bacteria in search of nutrients, organelle transport by molecular motors or sensing different ...
Mas Soler, Josep (Date of defense: 2017-01-09)
Optical Tweezers (OT) are a light-based non-invasive tool that has played an important role during the last decades in the field of biophotonics, together with the advances in optical microscopy techniques. Optical trapping ...
Florian Baron, Camilo (Date of defense: 2016-07-26)
Digital manufacturing constitutes a real industrial revolution that is transforming the production processes from the early stages of research and development to mass production and marketing. The biggest difference in ...
Kuntman, Ertan (Date of defense: 2019-12-19)
Jones matrix and nondepolarizing Mueller matrix are the basic elements of the calculus of polarization optics. In this thesis we discus other forms that can be used to represent optical properties of deterministic systems. ...
Caballero Lorenzo, Álvaro (Date of defense: 2016-06-23)
The main objective of this work is to study and optimize the amorphous silicon deposited in a PECVD reactor of recent acquisition, making it suitable for thin film and c-Si based solar cells. Optimization of intrinsic ...
González Herrero, Sergi (Date of defense: 2019-07-11)
L’orografia té un impacte molt important en la circulació del vent i en la precipitació a totes les escales, des de la microescala fins a la macroescala. La complexitat i la singularitat de les interaccions entre el relleu ...
Padullés Rulló, Ramon (Date of defense: 2017-06-22)
In 2009, the Spanish Ministry of Science and Innovation approved a proposal to modify the Global Positioning System (GPS) receiver and to allocate a Polarimetric (Pol) Radio Occultation (RO) antenna in the Spanish PAZ ...
Casellas Masana, Enric (Date of defense: 2022-05-20)
Precipitation phase discrimination at ground level constitutes a fundamental variable in many meteorological and hydrological applications, including avalanche hazards, winter road safety, and flooding from rain on snow ...
Altube Vázquez, Patricia (Date of defense: 2016-12-21)
Weather radar data and its downstream products are essential elements in weather surveillance and key parameters in the initialisation and validation of hydrological and meteorological models, among other downstream ...
del Moral Méndez, Anna (Date of defense: 2020-07-20)
Natural disasters of hydro-meteorological origin are the biggest risk worldwide. In Catalonia (NE of the Iberian Peninsula), severe weather and flash floods occur each year, resulting in major damage to property, losses ...
Tom, Thomas (Date of defense: 2023-07-13)
[eng] Global energy use has increased, causing a rapid shift in the climate. Renewable energy sources such as solar energy must replace fossil fuels to slow down this trend. In order to achieve this, the amount of power ...
Montornès Torrecillas, Alex (Date of defense: 2017-02-09)
The radiative transfer cannot be explicitly resolved in the atmospheric models for two reasons: i) a full treatment of the radiative transfer equation (RTE) requires a high amount of computational resources and ii) the ...
Rodríguez i Ballester, Oriol (Date of defense: 2021-05-06)
Tornadoes are the meteorological phenomenon which can produce the strongest surface wind on Earth, causing damage, injuries and fatalities. Several studies show that severe storm environments could be more frequent due to ...
Caballero Lucas, Francesc (Date of defense: 2019-10-15)
The use of femtosecond lasers has recently gained attention as a result of the recognition to Gérard Mourou and Donna Strickland with the award of the Nobel Prize in Physics 2018 "for their method of generating high-intensity, ...
