Zero-shot human attribute classification using pretrained VLMs
(2025) [Dissertation]Gender and ethnicity recognition is a key computer vision task in biometrics, surveil- lance, and demographic studies. Contrastive Language-Image Pre-training (CLIP) is a Vision-Language Model with promising zero-shot ... -
Uncovering the baryon cycle in the dwarf galaxy regime : a view from cosmological hydrodynamical simulations
(2025) [Thesis]Dwarf galaxies (stellar mass ≲ 109 M⊙) stand out as the most numerous galaxies across all cosmic time. While many studies primarily focus on the assembly of high-mass ga- laxies, the role of interactions, mergers, and AGN ... -
Revelando a estrutura central de quasares via ZTF/LSST
(2025) [Dissertation]Os quasares estão entre os objetos mais luminosos do Universo, compreendendo a extremidade de alta luminosidade dos Núcleos Ativos de Galáxias (AGN) onde um Buraco Negro Supermassivo (SMBH) central acreta matéria através ... -
Colapso do eixo duro de magnetização e recoil-curve overshoot em função da irradiação iônica e da temperatura
(2025) [Thesis]Diversos filmes policristalinos ferromagnéticos exibem picos centrados a 90◦ da posição do eixo de fácil magnetização nos gráficos de variações angulares da magnetização remanente após a saturação, MRS, e coercividade dos ... -
Superconductivity and anomalous electrical transport in bismuth-nickel systems
(2025) [Thesis]The Bismuth–Nickel (Bi–Ni) system has attracted significant attention due to the interplay of superconductivity, magnetism, topology, and spin–orbit coupling. Its richness lies in two distinct material realizations: the ... -
Effects of the generalized uncertainty principle on neutron stars
(2025) [Dissertation]Quantum Hadrodynamics type-I (QHD-1) is an effective relativistic field theory that describes nuclear matter through meson–nucleon interactions in the mean-field approximation. In the present work, this model is deformed ... -
The modified Friedmann equations in non-commutative space-time
(2025) [Dissertation]This work explores the implications of spacetime non-commutativity in modern cosmology using the Generalized Uncertainty Principle (GUP) proposed by Sastry. The study derives modified Friedmann equations from thermodynamic ... -
Unraveling the hydrogen storage mechanism in NixPd100-x (0 ≤ x ≤ 100) nanostructures
(2024) [Thesis]The increase in the world’s energy consumption and the use of non-renewable energy sources contribute to the energy and climate crisis. Thus, it is urgent to change the world’s energy matrix to a more sustainable and ... -
Distribuição de riqueza em modelos de trocas binárias em redes dinâmicas
(2025) [Thesis]Modelos matemáticos e técnicas computacionais originadas da física tem demonstrado grande aplicabilidade em diversas áreas, entre as quais destacamos a economia. A interação entre essas diferentes formas de conhecimento ... -
Holonomy observables for the Turaev–Viro model
(2025) [Thesis]This paper presents a study of holonomy observables for the Turaev–Viro model, a finite model of three-dimensional loop quantum gravity with a positive cosmological constant. A concise review of central aspects of loop ...
