Ergonomic and biomechanical evaluation of the use of computers, tablets and smart phones by children. A pilot study
(Springer Verlag, 2017)
The use of technological devices has widespread around the world. It is known that inappropriate or prolonged use of electronic devices can cause musculoskeletal discomfort or even illness. However, there are not many ...
Analysis of sEMG signals using discrete wavelet transform for muscle fatigue detection
(SPIE, 2017)
The purpose of the present article is to characterize sEMG signals to determine muscular fatigue levels. To do this, the signal is decomposed using the discrete wavelet transform, which offers noise filtering features, ...
Design of an electrogoniometer based on accelerometers for the evaluation of sports gesture in weight lifting
(Institute of Electrical and Electronics Engineers Inc., 2014)
This article describes the design and implementation of an electrogoniometer to measure joint angles during the execution of weight lifting exercises. The electrogoniometer consists of four microelectromechanical accelerometers ...
Ultrasound image enhancement: A review
(2012)
Medical ultrasound imaging uses pulsed acoustic waves that are transmitted and received by a hand-held transducer. This is a mature technology that it is widely used around the world. Among its advantages are that it is ...
A model for the development of programming courses to promote the participation of young women in STEM
(2021-10-26)
There is a gender gap in science, technology, engineering, and mathematics (STEM), and this is a global problem that affects society. However, it is worth pointing out that the gap is not uniform in all STEM fields. Women’s ...
Biomechanical Analysis of Common Postures during Mobile Phone Use
(2020-12-24)
The use of mobile phones for long periods of time has been associated with musculoskeletal and vision symptoms. This work uses simplified biomechanical models of the head, neck, back, and forearms to estimate the forces ...
On the compensation of uneven illumination in retinal images for restoration by means of blind deconvolution
(Institute of Electrical and Electronics Engineers Inc., 2016)
Retinal eye fundus images are used for diagnostic purposes, but despite controlled conditions in acquisition they often suffer from uneven illumination and blur. In this work, we propose the use of multi-channel blind ...
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 ...
