Analysis and classification of lung and muscular tissues in ultrasound images using 2D wavelet transform and machine learning
(2020-11-03)
Ultrasound has been considered a safe and accurate alternative to radiography and computerized tomography to diagnose lung diseases such as pneumonia. However, speckle noise, artifacts or certain conditions can difficult ...
LoRAWAN network coverage testing design using open-source low-cost hardware
(2020-12-01)
The Internet of Things (IoT) is considered to be one of the most radical technological advances of the century. The increasing amount of applications and devices, requires the deployment of a large network infrastructure ...
Optimal Charging Scheduling of Electric Vehicles based on Principal Component Analysis and Convex Optimization
(2020-07-30)
The widespread presence of plug-in Electric Vehicles (PEVs) in distribution power grids brings significant concerns regarding their energy demand and peak power requirements. In order to reduce the PEV load impact on power ...
Predictive power control for electric vehicle charging applications
(2020-12-01)
This paper presents a direct predictive power control (DPPC) design for vehicle charging applications. The proposed control design allows working in the Park's reference frame avoiding the usage of the phase-lock loops, ...
Implementation of a two-tank multivariable process for control education
(2020)
In many industrial processes there are multivariable systems which have more than one controlled variable and more than one manipulated variable. For the proper control of this type of process, the influence of one control ...
Who Participates in Popular Feasts and Festivals? An Empirical Approach from Cultural Economics Applied to the Carnival of Barranquilla (Colombia)
(2021-12-02)
The empirical analysis of individual participation in local and popular feasts and festivals is a field little explored by cultural economists. This article proposes a methodological scheme to analyse the profile of the ...
Narrativas para la emergencia del perdón, la reparación y la reconciliación en víctimas del conflicto armado en Colombia
(2020-01-01)
En los procesos de construcción de paz en Colombia, perdonar, reconciliarse y buscar la reparación de las víctimas se vuelven condiciones necesarias y decisivas. Estudios precedentes indican que cuando no son abordados ...
Substituted heterocycles as new candidates for liquid organic hydrogen carriers: In silico design from DFT calculations
(2021-02-24)
A new set of compounds based on N- and S-heterocycles were investigated through Density Functional Theory (DFT) for their use as liquid organic hydrogen carriers (LOHCs). The hydrogenated forms of these compounds could ...
Physico-Chemical and structural interpretation of discrete derivative indices on N-tuples atoms
(MDPI AG, 2016)
This report examines the interpretation of the Graph Derivative Indices (GDIs) from three different perspectives (i.e., in structural, steric and electronic terms). It is found that the individual vertex frequencies may ...
State-of-the-art active optical techniques for three-dimensional surface metrology: a review [Invited]
(2020)
This paper reviews recent developments of non-contact three-dimensional (3D) surface metrology using an active structured optical probe. We focus primarily on those active non-contact 3D surface measurement techniques that ...
