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 ...
α-bandlimited diffuser in fractional Fourier optics
(SPIE, 2016)
We propose a method for calculating appropriate α-band limited diffusers using the fractional Fourier transform. In order to do this, we implement a method for performing a numerical interpolation in the fractional Fourier ...
Sustainable boat transportation throughout electrification of propulsion systems: Challenges and opportunities
(Institute of Electrical and Electronics Engineers Inc., 2019)
Global use of carbon-based fuels increased by 1.6 % in 2017 and continued increasing in 2018, after managing to maintain emissions flat between 2014-2017. This trend deviates from the emissions trajectory required to fulfill ...
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 ...
Diffuser in Fractional Fourier Optics
(OSA - The Optical Society, 2016)
We propose a method for calculating a bandlimited diffuser with smooth spectrum in the Fresnel domain without any 2p phase ambiguities using the fractional Fourier transform. Such diffusers are necessary to avoid problems ...
A wearable system for biosignal monitoring in weightlifting
(Springer London, 2017)
The use of technological aids in sports has increased in the last years. These tools allow to register the athletes’ movements to evaluate and track their performance over time. With that information, it is possible to ...
Robust adaptive control of a planar 3RRR parallel robot for trajectory-tracking applied to crouch gait cycle in children with cerebral palsy
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper presents the modelling, control and simulation of a 3RRR planar parallel robot, using a robust adaptive control strategy. The objective of this work is to achieve the control over desired trajectory-tracking of ...
