• Improving approximate nearest neighbor search in HNSW graphs with data clustering 

  Vieira, Marco Antônio Athayde de Aguiar (2025) [Dissertação]

  Exhaustive strategies for search and information retrieval tasks over vector databases do not meet the runtime efficiency expectations of modern applications. Approximate Near- est Neighbor Search (ANNS) algorithms use ...
• Recursive filtering techniques for edge-aware filter analysis and implementation 

  Ferreira, Hermes Hofmeister (2025) [Tese]

  In this work, we aim to develop a formal mathematical method of analyzing edgeaware digital filters similar to how Fourier analysis can be used to understand linear filters. We believe there is a need for such a theory, ...
• Zero-shot human attribute classification using pretrained VLMs 

  Ceschini, Lucas Mayer (2025) [Dissertação]

  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 

  Freitas, Rodrigo Flores de (2025) [Tese]

  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 

  Gonçalves, Hygor Benati (2025) [Dissertação]

  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 

  Azeredo, Lucas Felipe Santos de (2025) [Tese]

  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 

  Silva, Gabriel Sant'Ana da (2025) [Tese]

  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 

  Gimenez, João Gabriel Galli (2025) [Dissertação]

  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 

  Silva, Rodrigo Fraga da (2025) [Dissertação]

  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 

  Matte, Lívia Pugens (2024) [Tese]

  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 ...
