(2022-12-28)
Los debates en torno al futuro del periodismo posibilitaron numerosas investigaciones sobre sus cambios en el nuevo contexto hiperdigitalizado. Sin embargo, se desconoce su impacto en la libertad de prensa, específicamente ...
Professional Autonomy and Structural Influences: Exploring How Homicides, Perceived Insecurity, Aggressions Against Journalists, and Inequalities Affect Perceived Journalistic Autonomy in Colombia
(2020)
Journalistic autonomy has been studied more frequently in countries with secure democracies in terms of journalists’ perceptions of freedom and independence to work in the midst of the controls, pressures, and influences ...
A quadratic convex approximation for optimal operation of battery energy storage systems in DC distribution networks
(2021-11-07)
This paper proposes a quadratic convex model for optimal operation of battery energy storage systems in a direct current (DC) network that approximates the original nonlinear non-convex one. The proposed quadratic convex ...

(2020-12-24)
Metacarpal injuries are a very widespread cause of consultations in emergency hospitals and are related to several types of injuries as well as, partial loss of mobility due to traffic, work or home accidents. After medical ...
Three-dimensional multimodal medical imaging system based on freehand ultrasound and structured light
(2021-05-21)
We propose a three-dimensional (3D) multimodal medical imaging system that combines freehand ultrasound and structured light 3D reconstruction in a single coordinate system without requiring registration. To the best of ...
Detection and removal of dust artifacts in retinal images via sparse-based inpainting
(2021-09-06)
Dust particle artifacts are present in all imaging modalities but have more adverse consequences in
medical images like retinal images. They could be mistaken as small lesions, such as microaneurysms.
We propose a method ...
Method for large-scale structured-light system calibration
(2021-05-24)
We propose a multi-stage calibration method for increasing the overall accuracy of a
large-scale structured light system by leveraging the conventional stereo calibration approach
using a pinhole model. We first calibrate ...
