Speckle reduction in echocardiography by temporal compounding and anisotropic diffusion filtering
(SPIE, 2015)
Echocardiography is a medical imaging technique based on ultrasound signals that is used to evaluate heart anatomy and physiology. Echocardiographic images are affected by speckle, a type of multiplicative noise that ...
Design and construction of a wearable wireless electrogoniometer for joint angle measurements in sports
(Springer Verlag, 2017)
Advances in the field of biomedical engineering have allowed the development of biometric devices to evaluate sport performance. This article describes the design and construction of a wearable electrogoniometer to monitor ...
Fetal ECG extraction using independent component analysis by Jade approach
(SPIE, 2017)
Fetal ECG monitoring is a useful method to assess the fetus health and detect abnormal conditions. In this paper we propose an approach to extract fetal ECG from abdomen and chest signals using independent component analysis ...
Region growing segmentation of ultrasound images using gradients and local statistics
(SPIE, 2017)
This paper describes a region growing segmentation algorithm for medical ultrasound images. The algorithm starts with anisotropic diffusion filtering to reduce speckle noise without blurring the edges. Then, region growing ...
Selection of a Stopping Criterion for Anisotropic Diffusion Filtering in Ultrasound Images
(Institute of Electrical and Electronics Engineers Inc., 2019)
Ultrasound imaging is a safe and cost-effective diagnostic tool, but the quality of the images is affected by speckle noise and artifacts. Anisotropic diffusion filters can be used to reduce noise and preserve the edges ...
Renewable energy production and demand dataset for the energy system of Colombia
(Elsevier Inc., 2020)
During the last decades, an increasing number of studies have focused their attention on the development of energy system models in order to facilitate sustainable energy planning strategies and understand the technical ...
Large scale integration of renewable energy sources (RES) in the future Colombian energy system
(Elsevier Ltd, 2019)
The diversification of the energy matrix, including larger shares of Renewable Energy Sources (RES), is a significant part of the Colombian energy strategy towards a sustainable and more secure energy system. Historically, ...
Vortex Search Algorithm for Optimal Sizing of Distributed Generators in AC Distribution Networks with Radial Topology
(Springer, 2019)
This paper proposes a vortex search algorithm (VSA) optimization for optimal dimensioning of distributed generators (DGs), in radial alternating current (AC) distribution networks. The VSA corresponds to a metaheuristic ...
Integration of PV Arrays in DC Power Grids via Unidirectional Boost Converters: A PBC Approach
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper presents a general control design for photovoltaic systems integrated with Direct-Current power grids by using an unidirectional boost converter. Passivity-based control (PBC) theory is used as a control technique ...
Analysis of Power Losses in Electric Distribution System Using a MATLAB-Based Graphical User Interface (GUI)
(Springer, 2019)
This paper describes a graphical user interface (GUI) developed in MATLAB that provides a user-friendly environment for analyzing the power loss behavior in distribution networks with radial configurations. This GUI allows ...
