Prediction of motorcyclist traffic crashes in Cartagena (Colombia): development of a safety performance function
(2021-04-05)
Motorcyclists account for more than 380 000 deaths annually worldwide from road tra c accidents. Motorcyclists are the most vulnerable road users worldwide to road safety (28% of global fatalities), together with cyclists ...
Conventional and advanced exergoeconomic indicators of a nitric acid production plant concerning the cooling temperature in compression Train’s intermediate stages
(2021-07-30)
In the refining and petrochemical industrial sector, large amounts of energy are used, so using the concept of exergy allows a rational use of this resource. In the different exergy and exergoeconomics studies applied in ...
2D CFD Modeling of Rapid Water Filling with Air Valves Using OpenFOAM
(2021-11-04)
The rapid filling process in pressurized pipelines has been extensively studied using mathematical models. On the other hand, the application of computational fluid dynamics models has emerged during the last decade, which ...
Assessment of Steady and Unsteady Friction Models in the Draining Processes of Hydraulic Installations
(2021-07-08)
The study of draining processes without admitting air has been conducted using only steady friction formulations in the implementation of governing equations. However, this hydraulic event involves transitions from laminar ...
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 ...
Difusión digital de objetos: expresiones culturales y turísticas en Colombia
(2021-08-09)
Los objetos y expresiones culturales hacen parte del turismo representativo de las regiones, por eso, este artículo tiene como propósito demostrar la visibilización de las mismas digitalmente ...
Smart UTB: An IoT platform for Smart Campus
(2021-09-29)
The Internet of Things (IoT) aims to create applications to improve people’s quality of life using novel protocols, sensor networks, cloud computing, middlewares and other technologies. These applications can be used in ...
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 ...
