FDD Channel Estimation Via Covariance Estimation in Wideband Massive MIMO Systems
(M D P I AG, 2020-02-10)
[Abstract] A method for channel estimation in wideband massive Multiple-Input Multiple-Output systems using hybrid digital analog architectures is developed. The proposed method is useful for Frequency-Division Duplex at ...
A Prototype of EEG System for IoT
(World Scientific Publishing Co. Pte. Ltd., 2020-05-04)
[Abstract] In this work, we develop open source hardware and software for eye state classification and integrate it with a protocol for the Internet of Things (IoT). We design and build the hardware using a reduced number ...

(MDPI AG, 2020-08-31)
[Abstract]
A comparison of different machine learning techniques for eye state identification through Electroencephalography (EEG) signals is presented in this paper. (1) Background: We extend our previous work by studying ...
Service-Learning Projects in University Degrees Based on Sustainable Development Goals: Proposals and Results
(MDPI AG, 2020-09-25)
[Abstract]
We present several Service-Learning projects developed considering Sustainable Development Goals to provide the students skills for the support of a sustainable society. This project begins with collecting ...
Eye State Identification Based on Discrete Wavelet Transforms
(MDPI, 2021)
[Abstract]: We present a prototype to identify eye states from electroencephalography signals captured from one or two channels. The hardware is based on the integration of low-cost components, while the signal processing ...
Proposals and Comparisons from One-Sensor EEG and EOG Human-Machine Interfaces
(MDPI AG, 2021-03-22)
[Abstract]
Human-Machine Interfaces (HMI) allow users to interact with different devices such as computers or home elements. A key part in HMI is the design of simple non-invasive interfaces to capture the signals associated ...
PICTOTEMPO: An App for Personal Organization in Autism Spectrum Disorders
(MDPI, 2021)
[Abstract] In this work, we develop a mobile application which allows to create digital schedules for children with autism spectrum disorder. These schedules comprise a sorted sequence of tasks or activities which facilitates ...
Development of Dual Activities with Micro:Bit for Interventions in People with Cerebral Palsy
(MDPI, 2021-10-12)
[Abstract] Several studies have shown that video games help to motivate users in different kinds of therapies. Therefore, in this work we developed a tool that includes dual activities for therapy, as well as a data system ...
PreLectO: An App for Cognitive Stimulation through Games in Early Childhood
(MDPI, 2021)
[Abstract] The goal of this work was to develop a mobile application for Android devices, with the objective of stimulating the cognitive skills of children from 0 to 6 years old who are suffering from learning disabilities, ...
Utilization of a Mobile Application for Motor Skill Evaluation in Children
(MDPI AG, 2021-01-12)
[Abstract]
The detection of needs in educational reinforcement must be done in the early stages of childhood during primary education to improve the acquisition of motor skills. An adequate early intervention can solve ...
