LRemoving Dust Artifacts in Retinal Images via Dictionary Learning and Sparse-Based Inpainting
(Institute of Electrical and Electronics Engineers Inc., 2019)
In the field of ophthalmology, retinal images are essential for the diagnosis of many diseases. These images are acquired with a device called the retinal camera. However, often small dust particles in the sensor produce ...
Validation of instruments as a guarantee of credibility in scientific research
(Editorial Ciencias Medicas, 2019)
Instrument validation is considered, for the scope of its scientific rigor, a type of study with its characteristics and procedures. The purpose of this work is to propose a methodology for the validation of a scientific ...
Direct power control for VSC-HVDC systems: An application of the global tracking passivity-based PI approach
(Elsevier Ltd, 2019)
This paper proposes a direct power control (DPC) for a high-voltage direct-current system using voltage source converters (VSC-HVDC) by applying passivity-based control theory. This system allows doing an efficient and ...
Evaluating Features Selection on NSL-KDD Data-Set to Train a Support Vector Machine-Based Intrusion Detection System
(Institute of Electrical and Electronics Engineers Inc., 2019)
The integrity of information and services is one of the more evident concerns in the world of global information security, due to the fact that it has economic repercussions on the digital industry. For this reason, big ...
A Structure-from-Motion Pipeline for Generating Digital Elevation Models for Surface-Runoff Analysis
(Institute of Physics Publishing, 2019)
Digital Elevation Models (DEMs) are used to derive information from the morphology of a land. The topographic attributes obtained from the DEM data allow the construction of watershed delineation useful for predicting the ...
Optimal power flow solution in direct current grids using Sine-Cosine algorithm
(Institute of Physics Publishing, 2019)
In the next years, Colombian power system will have the connection of distributed generators and constant power loads; Therefore, it is necessary to propose the analysis methods that allow establishing the minimum requirements ...
Optimal power flow studies in direct current grids: An application of the bio-inspired elephant swarm water search algorithm
(Institute of Physics Publishing, 2019)
Colombian power system is experienced important changes due to the large scale integration of renewable power generation based on solar and wind power; added to the fact that direct current networks have taken important ...
Alternative power flow method for direct current resistive grids with constant power loads: A truncated Taylor-based method
(Institute of Physics Publishing, 2019)
The power flow in electrical system permits analyzing and studying the steady-state behavior of any grid. Additionally, the power flow helps with the proper planning and management of the system. Therefore, it is increasingly ...
Developing a Robust Acquisition System for Fringe Projection Profilometry
(Institute of Physics Publishing, 2019)
Since Fringe Projection Profilometry (FPP) is an intensity-based coding strategy, it is prone to improper optical setup arrangement, surface texture and reflectance, uneven illumination distribution, among others. These ...
