Quality changes in fundus images of pseudophakic eyes
(Sociedad Espanola de Optica, 2018)
We consider the changes produced in the quality of eye fundus images of patients before and after cataract surgery with intraocular lens implantation and propose a measure to quantitatively assess those changes. Several ...
Desarrollo e implementación de un perfilómetro óptico por triangulación láser
(2020-12-24)
Profilometers are instruments commonly used in surface metrology tasks. These instruments play a key role in the industry, such as in manufacturing and quality assurance. However, conventional profilometry techniques require ...
What is the best triangulation approach for a structured light system?
(2020-05-18)
It has become customary to calibrate a camera-projector pair in a structured light (SL) system as a stereo-vision setup. The 3D reconstruction is carried out by triangulation from the detected point at the camera sensor ...
SPUD: Simultaneous phase unwrapping and denoising algorithm for phase imaging
(2020-05-01)
Recent methods for phase unwrapping in the presence of noise include denoising algorithms to filter out noise as a preprocessing stage. However, including a denoising stage increases the overall computational complexity ...

Active and reactive power conditioning using SMES devices with PMW-CSC: A feedback nonlinear control approach
(Ain Shams University, 2019)
The active and reactive power conditioning using superconducting magnetic energy storage (SMES) systems for low-voltage distribution networks via feedback nonlinear control is proposed in this paper. The SMES system is ...
On the nonlinear control of a single-phase current source converter for sinusoidal voltage generation
(2020)
Colombian power system is being transformed for the large-scale integration of renewable energy resources and energy storage systems; all of these are integrated by power electronic converters controlled by voltage and ...
Toward an adaptive protection scheme in active distribution networks: Intelligent approach fault detector
(2021-01)
Conventional protection schemes have proven insufficient for the protection of Active Distribution Networks (ADN). Novel protection schemes with an adaptive approach should be developed to guarantee the protection of ADN ...
Soft-computing approaches for rescheluding problems in a manufacturing industry
(2020-03-02)
Flexible manufacturing systems as technological and automated structures have a high complexity for scheduling. The decision-making process is made difficult with interruptions that may occur in the system and these problems ...
A chronological literature review of electric vehicle interactions with power distribution systems
(2020-06-11)
In the last decade, the deployment of electric vehicles (EVs) has been largely promoted. This development has increased challenges in the power systems in the context of planning and operation due to the massive amount of ...
