Inductive loops for traffic control
(2015-09)
Inductive Loop Detectors (ILDs) are the most commonly used sensors in traffic management
systems. This work provides a system capable of obtaining simultaneous inductive
signatures of vehicles traveling on a roadway with ...
Calculation of the Connected Dominating Set Considering Vertex Importance Metrics
(M D P I AG, 2018-01-28)
[Abstract] The computation of a set constituted by few vertices to define a virtual backbone supporting information interchange is a problem that arises in many areas when analysing networks of different natures, like ...
Hybrid Supervised-Unsupervised Channel Estimation Scheme with Dynamic Transmission of Pilots
(Springer, 2011-02)
[Abstract] Multiple-Input Multiple-Output (MIMO) digital communications standards typically include pilot symbols in the definition of the transmit signals with the purpose of acquiring the Channel State Information (CSI) ...
A low-cost decision-aided channel estimation method for Alamouti OSTBC
(Springer, 2013-11)
[Abstract] In wireless communication systems, channel state information (CSI) acquisition is typically performed at the receiver side every time a new frame is received, without taking into account whether it is really ...
A Novel Strategy for Improving the Quality of Embedded Zerotree Wavelet Images Transmitted over Alamouti Coding Systems
(Springer, 2011)
[Abstract] This work deals with the transmission of images, previously coded using the Embedded Zerotree Wavelet (EZW) transform, over wireless systems in which
Space-Time Coding (STC) is used. It is shown how the system ...
Brain-Computer Interfaces for Internet of Things
(M D P I AG, 2018-09-17)
[Abstract] A brain-computer interface for controlling elements commonly used at home is presented in this paper. It includes the electroencephalography device needed to acquire signals associated to the brain activity, the ...
Aplicación web para evaluación y seguimiento del rendimiento de asignaturas y titulaciones universitarias
(Universidade de Vigo, Facultade de Ciencias da Educacion, 2010)
[Summary] The adaptation of the university studies to the current European Higher Education Area (EHEA) requires the set up of mechanisms, which allow performance evaluation of the subjects compounding the new university ...
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 Comparative Study of Low Cost Open Source EEG Devices
(MDPI AG, 2019-08-05)
[Abstract] A comparison of two open source electroencephalography devices designed to acquire signals associated to the brain activity is presented in this work. The experiments are developed considering the task of ...
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 ...
