Data augmentation via warping transforms for modeling natural variability in the corneal endothelium enhances semi-supervised segmentation
(2024-11-12)
Image segmentation of the corneal endothelium with deep convolutional neural networks (CNN) is challenging due to the scarcity of expert-annotated data. This work proposes a data augmentation technique via warping to enhance ...
La fiducia mercantil como alternativa para los procesos de sucesión por causa de muerte en Colombia
(2024-12)
En Colombia, el derecho de sucesiones se enmarca en una iusteoría formalista que ha llevado a la inaplicación de sus disposiciones desde las prácticas del conglomerado social. Las causas principales son la excesiva limitación ...
Shear stress solutions for curved beams: a structural analysis approach
(2024-12-06)
The shear stress on isotropic curved beams with compact sections and variable thickness is
