Design and Empirical Validation of a LoRaWAN IoT Smart Irrigation System
(MDPI AG, 2020-04-21)
[Abstract]
In some parts of the world, climate change has led to periods of drought that require managing efficiently the scarce water and energy resources. This paper proposes an IoT smart irrigation system specifically ...
Moving to e-Service Learning in Higher Education
(MDPI, 2022)
[Abstract] Service Learning is a methodology in which students achieve academic and transversal competences related to the curriculum of a subject while performing a service for the benefit of the community. With the ...
Design and Experimental Validation of an Augmented Reality System With Wireless Integration for Context Aware Enhanced Show Experience in Auditoriums
(Institute of Electrical and Electronics Engineers, 2020-12-30)
[Abstract]
The development of multiple cultural and social related activities, such as shows related with the performing arts, conferences or presentations rely on facilities such as auditoriums, theatres and conference ...
A cost-effective IoT system for monitoring Indoor radon gas concentration
(M D P I AG, 2018-07-08)
[Abstract] Radon is a noble gas originating from the radioactive decay chain of uranium or thorium. Most radon emanates naturally from the soil and from some building materials, so it can be found in many places around the ...
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 ...
DASBE: Decision-Aided Semi-Blind Equalization for MIMO Systems with Linear Precoding
(Akademie Ved Ceske Republiky * Ustav Informatiky, 2010)
[Abstract] Multiple-Input Multiple-Output (MIMO) digital communications standards usually acquire Channel State Information (CSI) by means of supervised algorithms, which implies a loss of performance since pilot symbols ...
A Novel Hybrid Approach to Improve Performance on Frequency Division Duplex Systems with Linear Precoding
(Springer, 2010)
[Abstrtact] Linear precoding is an attractive technique to combat interference in multiple-input multiple-output systems because it reduces costs and power consumption in the receiver equipment. Most of the frequency ...
Developing the Next Generation of Augmented Reality Games for Pediatric Healthcare: An Open-Source Collaborative Framework Based on ARCore for Implementing Teaching, Training and Monitoring Applications
(MDPI AG, 2021-03-07)
[Abstract]
Augmented Reality (AR) provides an alternative to the traditional forms of interaction between humans and machines, and facilitates the access to certain technologies to groups of people with special needs like ...
Wideband User Grouping for Uplink Multiuser mmWave MIMO Systems With Hybrid Combining
(Institute of Electrical and Electronics Engineers, 2021-03-10)
[Abstract]
Analog-digital hybrid precoding and combining schemes constitute an interesting approach to millimeter-wave (mmWave) multiple-input multiple-output (MIMO) systems due to the low hardware complexity and/or low ...
