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 algorithms combine discrete wavelet transform and linear discriminant analysis. We consider different parameters: nine different wavelets and two features extraction strategies. A set of experiments performed in real scenarios allows to compare the performance in order to determine a configuration with high accuracy and short response delay.

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 with the user’s intentions. In this work, we have designed two different approaches based on Electroencephalography (EEG) and Electrooculography (EOG). For both cases, signal acquisition is performed using only one electrode, which makes placement more comfortable compared to multi-channel systems. We have also developed a Graphical User Interface (GUI) that presents objects to the user using two paradigms—one-by-one objects or rows-columns of objects. Both interfaces and paradigms have been compared for several users considering interactions with home elements.

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 some detected difficulties, thus contributing to children’s motor progress and mitigating possible deficiencies such as weak motor coordination. In this work, we present a mobile application (app) that allows physiotherapists to design activities for the evaluation of motor skills. These activities can be adapted to the child’s progress and the corresponding reinforcement needs. We tested the app with children from ages 6 to 12, corresponding to the six primary school grades. The results show that these children did not have notable motor difficulties, although children in lower primary school years showed a higher level of error in movement precision. The results allow us to establish reference values for a future comparison with collectives with motor difficulties.

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 initial impressions from surveys and reflections to know both the students’ expectations and their degree of involvement in the development of a sustainable society. Next, the students design academic projects taking into account the needs of the specific collective to which the Service-Learning activity is oriented. When this design has finished, such projects are developed with the users and the activity is evaluated. During 2019–2020, these projects were done with four entities oriented to people either with Asperger’s syndrome, Down syndrome, Alzheimer’s disease or mental health illnesses. A total of 35 and 10 students, respectively, from the Bachelor’s Degree of Engineering in Industrial Design and Product Development and from the Master’s Degree in Professorship of High School have participated in this experience. We analyze the results from the perspective of the different agents involved, considering both qualitative and quantitative metrics. The results show that both users and staff are satisfied with this collaboration between the university and their entities. Moreover, this experience clearly has contributed to a better personal and professional student’s development.

This work presents a mobile application to complement and reinforce the specific physical activities in children through training prior to such activities and monitoring their progress after it. This experiment has been developed on a healthy population of children from an education centre in the area of A Coruña. The results show increasing errors for lower primary school years, as expected, and also strongly dependent on the motor path type or characteristic. Therefore, this tool will be suitable for use with children affected by motor coordination difficulties.

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 several techniques for the extraction of the features corresponding to the mental states of open and closed eyes and their subsequent classification; (2) Methods: A prototype developed by the authors is used to capture the brain signals. We consider the Discrete Fourier Transform (DFT) and the Discrete Wavelet Transform (DWT) for feature extraction; Linear Discriminant Analysis (LDA) and Support Vector Machine (SVM) for state classification; and Independent Component Analysis (ICA) for preprocessing the data; (3) Results: The results obtained from some subjects show the good performance of the proposed methods; and (4) Conclusion: The combination of several techniques allows us to obtain a high accuracy of eye identification.

In this paper we focus on the issue related to finding the resolving connected dominating sets (RCDSs) of a graph, denoted by G. The connected dominating set (CDS) is a connected subset of vertices of G selected to guarantee that all vertices in the graph are connected to vertices in the CDS. The connected dominating set with minimum cardinality, or minimum CDS (MCDS), is an adequate virtual backbone for information interchange in a network. When distinct vertices of G have also distinct representations with respect to a subset of vertices in the MCDS, it is said that the MCDS includes a resolving set (RS) of G. With this work, we explore different strategies to find the RCDS with minimum cardinality in complex networks where the vertices have different importances.

This work shows a system that appropriately integrates a Brain–Computer Interface and an Internet of Things environment based on eye state identification. The Electroencephalography prototype for brain electrical signal acquisition has been designed by the authors. This prototype uses only one electrode and its size is very small, which facilitates its use for all type of applications. We also design a classifier based on the simple calculation of a threshold ratio between alpha and beta rhythm powers. As shown from some experiment results, this threshold-based classifier shows high accuracies for medium response times, and according to that state identification any smart home environment with those response requirements could correctly act, for example ON–OFF switching room lights.

In this work we present a new method for determining relative positions between one moving object, modelled by a bounding spheroid, and surrounding static objects, modelled by circular hyperboloids of one sheet. The proposed strategy is based on the real-time calculation of the coefficients of degree three polynomial. We propose several algorithms for two real applications of this geometric problem: the first one, oriented to the design of video games, and the second one, devoted to surveillance tasks of a quadcopter in industrial or commercial environments.

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 determining the user eye state i.e., open eyes or closed eyes, applying an algorithm based on computing the sliding Fourier Transform of the captured signals.

During years, professors of higher education focused on the outcome of the assimilation of information through learning (i.e., in the acquisition of knowledge). In a European context, the Bologna Process has accelerated and spread the process of defining explicit learning outcomes for higher education programs, including those in terms of general competences and transferable skills. Our teaching experience in engineering degrees have shown that these students have difficulties for understanding the math basics of some disciplines. For greater effectiveness in knowledge acquisition, we consider as an essential issue the inclusion of laboratory activities based on computer simulations performed using software. For acquiring those general competences and transferable skills, our proposal also includes several projects in which our students must develop skills such as communication, teamwork or problem solving. We have observed that such projects allow students the development of their creativity, an improvement in oral and written communication, and also an optimal training for the B.S. degree project work and even for their future professional life.

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 wireless, brain, or social networks. Recent papers propose obtaining such a set of vertices by computing the connected dominating set (CDS) of a graph. In recent works, the CDS has been obtained by considering that all vertices exhibit similar characteristics. However, that assumption is not valid for complex networks in which their vertices can play different roles. Therefore, we propose finding the CDS by taking into account several metrics which measure the importance of each network vertex e.g., error probability, entropy, or entropy variation (EV).

This work proposes an hybrid precoding method in a Multiple-Input/Multiple-Output Frequency Division Duplex (MIMO FDD) system with the objective of reducing the load associated to transmit side information needed to adapt precoding matrices in both the transmitter and the receiver. The type of precoding is determined at the transmitter by using a simple rule that takes into account a receive Signal–to–Noise Ratio (SNR) estimate. The receiver computes the magnitude of the channel level fluctuations and determines the time instants when long pilot sequences are needed to estimate the precoding matrices. Using a low cost feedback channel, the receiver indicates to the transmitter both the type of precoder and transmit frames to be used.

This paper presents a novel home automation system named HASITE (Home Automation System based on Intelligent Transducer Enablers), which has been specifically designed to identify and configure transducers easily and quickly. These features are especially useful in situations where many transducers are deployed, since their setup becomes a cumbersome task that consumes a significant amount of time and human resources. HASITE simplifies the deployment of a home automation system by using wireless networks and both self-configuration and self-registration protocols. Thanks to the application of these three elements, HASITE is able to add new transducers by just powering them up. According to the tests performed in different realistic scenarios, a transducer is ready to be used in less than 13 s. Moreover, all HASITE functionalities can be accessed through an API, which also allows for the integration of third-party systems. As an example, an Android application based on the API is presented. Remote users can use it to interact with transducers by just using a regular smartphone or a tablet.
