Torre Estévez, Víctor de la (Date of defense: 2023-11-24)
[eng] We study discrete energy minimization problems on two-point homogeneous manifolds. Since finding N-point configurations with optimal energy is highly challenging, recent approaches have involved examining random point ...
Sala Mirabet, Ferran (Date of defense: 1986-01-01)
Se ha desarrollado un modelo galáctico no estacionario con simetria cilíndrica basado en las hipótesis de Chandrasekhar, habiéndose caracterizado las funciones que lo determinan. La forma obtenida para el potencial ha ...
Planas Corbella, José María, 1910-1936 (Date of defense: 1934-06-16)
En una serie de recientes trabajos, donde se estudian a fondo muchos problemas esenciales de la moderna teoría de las funciones de dos variables complejas, F. SEVERI ha establecido las bases de una fundamentación geométrica ...
Campello Román, Víctor Manuel (Date of defense: 2023-12-15)
[eng] The field of Artificial Intelligence (AI) has undergone a revolution in recent years with the advent of more efficient computing hardware and well-documented software for model development. Many fields are being ...
Pezzano, Giuseppe (Date of defense: 2023-07-27)
[eng] During the last few years, AI development in deep learning has been going so fast that even important researchers, politicians, and entrepreneurs are signing petitions to try to slow it down. The newest methods for ...
Rodríguez Soto, Manel (Date of defense: 2023-06-26)
[eng] As autonomous agents become increasingly sophisticated and we allow them to perform more complex tasks, it is of utmost importance to guarantee that they will act in alignment with human values. This problem has ...
Sunyer i Balaguer, Ferran, 1912-1967 (Date of defense: 1962-10-23)
En una serie de Notas y Memorias, el autor de ésta demostró que cuando la serie de Taylor, que representa una función entera u holomorfa en el círculo unidad, es suficiente lagunar, la función toma la totalidad de los ...
Vaquer i Timoner, Josep, 1928-2020 (Date of defense: 2020-01-01)
Según un conocido teorema de Wedderburn, toda álgebra normal y simple es el producto directo (tensorial) de un álgebra total de matrices y un álgebra de división. A partir de aquí R. Brauer divide las álgebras normales y ...
Bertiche Argila, Hugo (Date of defense: 2022-11-17)
[eng] Machine learning has experienced a soar thanks to the proliferation of deep learning based methodologies. 3D vision is one of the many fields that benefited from this trend. Within this domain, I focused my research ...
Selva Castelló, Javier (Date of defense: 2023-12-19)
[eng] With the aim of creating artificial systems capable of mirroring the nuanced understanding and interpretative powers inherent to human cognition, this thesis embarks on an exploration of the intersection between human ...
Martínez Legaz, Juan Enrique (Date of defense: 1981-10-29)
En este trabajo se definen y estudian los conceptos de H-convexidad y H-conjugación, siendo H una familia de funciones reales de variable real cerrada para el supremo puntual de tal manera que coinciden con los clásicos ...
Pascual i Guinovart, Guillem (Date of defense: 2023-02-17)
[eng] Deep Learning (DL) has gained traction in the last years thanks to the exponential increase in compute power. New techniques and methods are published at a daily basis, and records are being set across multiple ...
Salat Moltó, Martí (Date of defense: 2022-11-15)
[eng] Framed within the areas of algebraic geometry and commutative algebra, this thesis contributes to the study of sheaves and vector bundles on toric varieties. From different perspectives, we take advantage of the ...
