Silva, Higor Luis (author), Machado Guimarães, Thiago Augusto (author), Castro, Saullo G.P. (author)Modular structures come with the promise of efficient manufacturing and reduced maintenance costs. The amount of modularization is usually limited by weight efficiency, meaning that the minimum weight always lies on the most customized design, where all the structural elements are allowed to be different across the structural domain. This work...conference paper 2023

(author), Silva, Julio Daniel Machado (author), Judice, Sicilia (author)We use a method combining experimental design, sketch-based reservoir modelling, and flow diagnostics to rapidly screen the impact of sedimentological heterogeneities on CO2 migration and storage by stratigraphic trapping. Experimental design allows efficient exploration of a wide parameter space, sketch-based modelling enables rapid...conference paper 2022

(author), Silva, Julio Daniel Machado (author), Judice, Sicilia (author), Rahman, Fazilatur (author), Sousa, Mario Costa (author)Production of subsurface heat from geothermal sources and subsurface storage of heat (and cool) are important for energy transition. Doublets for geothermal and warm- and cold wells for aquifer thermal energy storage (ATES) depend on circulation of fluids and heat. Estimating the potential and feasibility of such systems requires a careful...conference paper 2022

Silva, André (author), Nogueira, Rita (author), Bogas, J. Alexandre (author), Rodrigues, Miguel (author)Concrete is the most widely material used in the construction industry. However, it has a great environmental impact, mainly because of cement manufacture and the inherent CO2 emissions into the atmosphere. This research intends to contribute to the reduction of the environmental impact of the concrete industry through the uptake of CO2 during...conference paper 2021

de Azambuja, Carolina M. (author), Silva, Eugênia F. (author), Capuzzo, Valdirene M.S. (author)The High Strength Concretes (HSC) provided significant advances in civil construction, due its superior strength, efficiency and durability. Due to the high content of cement, low water/cement ratio and mineral additions, it is essential to avoid the emergence of tensile stresses generated autogenous shrinkage and consequently the cracking of...conference paper 2021

Van Egmond, R. (author), De Ridder, H. (author), Pappas, T.N. (author), Silva, P.M. (author)We investigate the effect of contrast enhancement on the subjective roughness of visual textures. Our analysis is based on subjective experiments with seventeen images from the CUReT database in three variants: original, synthesized textures, and contrast-enhanced synthesized textures. In Experiment 1, participants were asked to adjust the...conference paper 2014
