Hölder continuous maps on the interval with positive metric mean dimension
(2023-11)
Fix a compact metric space X with finite topological dimension. Let C0(X) be the space of continuous maps on X and Hα(X) the space of α-Hölder continuous maps on X, for α ∈ (0, 1]. Let H1(X) be the space of Lipschitz ...
Self-supervised Deep-Learning Segmentation of Corneal Endothelium Specular Microscopy Images
(2023)
Computerized medical evaluation of the corneal endothelium is challenging because it requires costly equipment and specialized personnel, not to mention that conventional techniques require manual annotations that are ...
Density of the level sets of the metric mean dimension for homeomorphisms
(2023-12-10)
Let N be an n-dimensional compact riemannian manifold, with n ≥ 2. In this paper, we prove that for any α ∈ [0, n], the set consisting of homeomorphisms on N with lower and upper metric mean dimensions equal to α is dense ...

Improving Pump Characteristics through Double Curvature Impellers: Experimental Measurements and 3D CFD Analysis
(2023-07-27)
The outlet angle and shape of impeller blades are important parameters in centrifugal pump
design. There is a lack of detailed studies related to double curvature impellers in centrifugal pumps
in the current literature; ...
A machine learning model to predict standardized tests in engineering programs in Colombia
(2023-08)
This research develops a model to predict the results of Colombia’s national standardized test for Engineering programs. The research made it possible to forecast each student’s results and thus make decisions on reinforcement ...
