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 ...
Manifestaciones clínicas de la Insensibilidad congénita al dolor con anhidrosis
(2019-02-03)
La insensibilidad congénita al dolor con anhidrosis (HSAN-IV o CIPA) es una enfermedad rara con sintomatología multisistémica, que impacta el funcionamiento cognitivo, afectando negativamente la calidad de vida los pacientes ...
La participación política como resistencia: el caso de la Agencia de Derechos Humanos en Montes de María, Colombia
(2019-05)
La participación significa para las víctimas del conflicto armado en Colombia una apuesta por la agencia creativa para la reparación de los derechos vulnerados por el conflicto. Este trabajo presenta los resultados del ...
IMMAN: free software for information theory-based chemometric analysis
(Kluwer Academic Publishers, 2015)
Abstract: The features and theoretical background of a new and free computational program for chemometric analysis denominated IMMAN (acronym for Information theory-based CheMoMetrics ANalysis) are presented. This is ...
On the illumination compensation of retinal images by means of the bidimensional empirical mode decomposition
(SPIE, 2015)
Retinal images are used for diagnostic purposes by ophthalmologists. However, despite controlled conditions in acquisition retinal images often suffer from non-uniform illumination which hinder their clinical use. In this ...
Power flow approximation for DC networks with constant power loads via logarithmic transform of voltage magnitudes
(Elsevier Ltd, 2019)
This paper proposes a logarithmic transformation of voltages (LTVM) for the power flow in DC grids. This problem is non-linear due to the presence of constant power loads (CPLs), which also introduce a negative resistance ...
Programmable diffractive optical elements for extending the depth of focus in ophthalmic optics
(SPIE, 2015)
The depth of focus (DOF) defines the axial range of high lateral resolution in the image space for object position. Optical devices with a traditional lens system typically have a limited DOF. However, there are applications ...
