Ayats López, Roger (Date of defense: 2022-04-22)
Turbulence is one of the major concerns for most technological problems involving fluid motion. Specially in aeronautics, a turbulent boundary layer results in structural stresses, vibrations and higher aircraft drag, ...
Gao, Chen (Date of defense: 2022-05-18)
Due to the rich dynamic properties of the equilibria of the Restricted Three Body Problem (RTBP), the libration point orbits (LPOs) around them are ideal locations for scientific missions. Fortunately, these invariant ...
Moreno Ramos, Eduardo (Date of defense: 2022-05-30)
Cell motility is important in many biological processes. Some examples relay in epidermal cells moving towards lesions during wound healing, neutrophils cells migrating towards sites of bacterial infection as part of the ...
Tipantuña Tenelema, Christian José (Date of defense: 2022-03-29)
Ever-increasing energy consumption, the depletion of non-renewable resources, the climate impact associated with energy generation, and finite energy-production capacity are important concerns worldwide that drive the ...
Deshmukh, Chetan (Date of defense: 2022-04-29)
Encoding information into quantum mechanical properties of a system can lead to applications many fields, including computing and communication. Devices that will enable these applications could be part of a quantum network ...
Bordalba Llaberia, Ricard (Date of defense: 2021-10-29)
This work proposes a methodology for kinodynamic planning and trajectory control in robots with closed kinematic chains. The ability to plan trajectories is key in a robotic system, as it provides a means to convert ...
Shabani, Arya (Date of defense: 2021-07-05)
The position analysis problem is a fundamental issue that underlies many problems in Robotics such as the inverse kinematics of serial robots, the forward kinematics of parallel robots, the coordinated manipulation of ...
Sarabandi, Soheil (Date of defense: 2021-04-27)
Since the map from quaternions to rotation matrices is a 2-to-1 covering map, this map cannot be smoothly inverted. As a consequence, it is sometimes erroneously assumed that all inversions should necessarily contain ...
Fernández-Pedrera Balsells, Marta (Date of defense: 2022-05-24)
This thesis analyses the relationships between hydrodynamics (and their forcings) and biological variables in Fangar Bay based on in situ observations, numerical models and satellite data. Fangar Bay is a relatively small, ...
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 ...
Rony, Rakibul Islam (Date of defense: 2022-05-13)
Older generations of wireless networks, such as 1G and 2G were deployed using leased line, copper or fibre line as backhaul. Later, in 3G and 4G, microwave wireless links have also worked as backhaul links while the ...
Paz Ortiz, Alejandro Iván (Date of defense: 2022-05-03)
This manuscript explores automatic programming of sound synthesis algorithms within the context of the performative artistic practice known as live coding. Writing source code in an improvised way to create music or visuals ...
Cots Corominas, Carles (Date of defense: 2022-05-06)
This thesis develops a new structural strengthening technique: converting existing reinforced concrete structures to composite sections by inserting connectors after controlled demolition with high-pressure water. The key ...
Elu Etxano, Ugaitz (Date of defense: 2022-05-03)
In the last decades, intense carrier-envelope-phase-stable (CEP-stable) and near-single-cycle, coherent mid-infrared sources have become charming for a variety of applications in physics, chemistry and biology. In particular, ...
Du, Sen (Date of defense: 2022-05-13)
Firstly, an External Model Deformation Decomposition based Persistent Scatters Interferometry (EMDD-PSI) method has been proposed. This method first uses original interferograms to optimize the parameters of the external ...
Amorim, Samuel (Date of defense: 2012-05-14)
Human and economic losses caused by landslides have attracted the interest of the scientific community for the identification of the threatened areas and preventing their consequences. The goal of the landslide susceptibility ...
Aghazadeh Dafsari, Seyed Rasoul (Date of defense: 2022-05-03)
Antenna array systems have a broad range of applications in radio frequency (RF) and ultra-wideband (UWB) communications to receive/transmit electromagnetic waves from/to the sky. They can enhance the amplitude of the input ...
Valle Fraga, Juan José (Date of defense: 2022-04-06)
Today, the most common form of mass-production semiconductor device fabrication is Complementary Metal-Oxide Semiconductor (CMOS) technology. The dedicated Integrated Circuit (IC) interfaces of commercial sensors are ...
Borraz Martínez, Sergio (Date of defense: 2022-05-12)
In the cultivation of fruit trees, the most common is to work with cuttings. In this way, the grafted fruit tree variety offers specific fruit qualities and the rootstock offers certain agronomic and adaptation characteristics. ...
