The constant and rapid population growth goes hand in hand with an increased demand for services that governments have the duty to satisfy with the problem of limited financial resources. Transport infrastructure is one ...
Saura Perisé, Jaime (Date of defense: 2022-06-22)
This doctoral thesis has been developed to provide a new point of view and a new approach to the analysis and study of uncontrolled bridge rectifiers. The methodology developed has been generalized to extend the study to ...
Raymond, Yago (Date of defense: 2021-09-13)
Bone grafting is a common medical practice in today’s society, being bone the second most transplanted tissue worldwide after blood. Therefore, it represents a field of major interest for both, biomedical research and the ...
Tabatabaeimehr, Fatemehsadat (Date of defense: 2022-06-02)
Network automation has been long time envisioned. In fact, the Telecommunications Management Network (TMN), defined by the International Telecommunication Union (ITU), is a hierarchy of management layers (network element, ...
Collico, Stefano (Date of defense: 2022-06-13)
The task of geotechnical site characterization includes defining the layout of ground units and establishing their relevant engineering properties. This is an activity in which uncertainties of different nature (inherent, ...
Arocas Pérez, José (Date of defense: 2022-05-18)
Some electrical devices in direct current (DC) networks, under certain operating characteristics, behave as constant power loads (CPLs). This behavior is defined by presenting negative incremental resistance, compromising ...
Valdés Alonzo, Gabriel Rolando (Date of defense: 2022-06-03)
Identifying the constitutive relations of materials is an essential task to understand their behavior. Classical methods like testing can be effective in understanding these relationships, but introducing models can lead ...
Peredo Andrade, Oscar Francisco (Date of defense: 2022-06-09)
Classical geostatistical methods are based on the hypothesis of stationarity, which allows to apply repetitive sampling in different locations of the spatial domain, in order to obtain enough information to infer cumulative ...
Barzegar, Sima (Date of defense: 2022-06-03)
This Ph.D. thesis focuses on the reliable autonomous operation of multilayer optical networks. The first objective focuses on the reliability of the optical network and proposes methods for health analysis related to ...
Torres Garrido, Diego (Date of defense: 2021-10-07)
Titanium (Ti) has been used for decades for bone prostheses due to its mechanical performance and good biocompatibility. However, the stress shielding effect, as a result of the stiffness mismatch between titanium and the ...
