Abstract The incorporation of expanded polystyrene (EPS) into concrete reduces its density, but also its mechanical properties. Therefore, the concrete with EPS is generally considered as a non-structural material. In this study, destructive and nond

Tomographic Images of Tree Trunks Generated Using Ultrasound and Post-processed Images: Influence of the Number of Measurement Points
Autor: Stella Stopa Assis Palma, Raquel Gonçalves
Publikováno v: BioResources, Vol 17, Iss 4, Pp 6638-6655 (2022)
Tomography is a technique increasingly used in tree inspections. This technique can be performed in two stages: field testing and postimage processing. To feed the tomographic image construction software, it is necessary to adopt a measurement grid c

Tomographic Images Generated from Measurements in Standing Trees Using Ultrasound and Postprocessed Images: Methodological Proposals for Cutting Velocity, Interpolation Algorithm and Confusion Matrix Metrics Focusing on Image Quality
Autor: Mariana Nagle Dos Reis, Stella Stopa Assis Palma, Raquel Gonçalves
Publikováno v: Forests; Volume 13; Issue 11; Pages: 1935
Tomographic images generated by wave propagation are important in tree inspections and can be performed in an economically more accessible way using conventional equipment and postprocessed images, but improvements are necessary to increase image qua

Desenvolvimento de metodologia para obtenção de imagem do contorno de fustes irregulares
Autor: Sergio Silva Rodrigues Junior, Stella Stopa Assis Palma, Danilo Profeta Ziller, Raquel Goncalves
Publikováno v: Revista dos Trabalhos de Iniciação Científica da UNICAMP.
Por se tratar de seres vivos, as árvores podem apresentar irregularidades e ou anormalias, além de serem passíveis de ataques biológicos, que podem levar a sua deterioração e, consequentemente, a redução de sua rigidez, podendo resultar em qu

Interference from Knots, Wave Propagation Direction, and Effect of Juvenile and Reaction Wood on Velocities in Ultrasound Tomography
Autor: Guilherme Alonso Martins, Stella Stopa Assis Palma, Raquel Gonçalves, Candida Pereira Costa, Alex Julio Trinca, Mariana Nagle dos Reis
Publikováno v: BioResources. 13
Acoustic tomography is based on the velocity variation inside the inspected element. However, wood is heterogeneous and anisotropic, which causes natural velocity variations. In wood, the great challenge to apply this technology is to interpret and d
