abstract = {This letter formally introduces the concept of interaction model (IM), which has been used either directly or tangentially in previous works but never defined. Broadly speaking, an IM consists of the use of a mixture of dimensionality reduction (DR) techniques within an interactive data visualization framework. The rationale of creating an IM is the need for simultaneously harnessing the benefit of several DR approaches to reach a data representation being intelligible and/or fitted to any user’s criterion. As a remarkable advantage, an IM naturally provides a generalized framework for designing both interactive DR approaches as well as readily-to-use data visualization interfaces. In addition to a comprehensive overview on basics of data representation and dimensionality reduction, the main contribution of this manuscript is the elegant definition of the concept of IM in mathematical terms.},

abstract = {The Big Data analysis allows to generate knowledge based on mathematical models that surpass human capabilities, and therefore it is necessary to have robust computer systems. In this connection, the dimensionality reduction (DR) allows to perform approximations to make data perceptible in a simple and compact way while also the computational cost is reduced. Additionally, interactive interfaces enable the user to work with algorithms involving complex mathematical and statistical processes typically aimed at providing weighting factors to each RD algorithm to find the best way to represent data at a low dimension. In this study, a bibliographic re-view of the different models of interactive interfaces for the analysis of Big Data using RD is presented, by considering different, existing proposals and approaches on how to display the information. Particularly, those approaches based on mental processes and uses of color along with an intuitive handling are of special interest.},

abstract = {Epilepsy occurs when localized electrical activity of neurons suffer from an imbalance. One of the most adequate methods for diagnosing and monitoring is via the analysis of electroencephalographic (EEG) signals. Despite there is a wide range of alternatives to characterize and classify EEG signals for epilepsy analysis purposes, many key aspects related to accuracy and physiological interpretation are still considered as open issues. In this paper, this work performs an exploratory study in order to identify the most adequate frequently-used methods for characterizing and classifying epileptic seizures. In this regard, a comparative study is carried out on several subsets of features using four representative classifiers: Linear Discriminant Analysis (LDA), Quadratic Discriminant Analysis (QDA), K-Nearest Neighbor (KNN), and Support Vector Machine (SVM). The framework uses a well-known epilepsy dataset and runs several experiments for two and three classification problems. The results suggest that DWT decomposition with SVM is the most suitable combination.},

Según (Piaget & Inhelder, 1997) "El conocimiento no se obtiene de los objetos sino de las acciones que realice sobre los objetos", en consecuencia, la aplicación de métodos lúdicos de enseñanza-aprendizaje mediante el uso de la tecnología, como dispositivos electrónicos y TICs pretende lograr dicha meta.

Abstract 

Motor skills are defined as "the control that the child is able to have on his own body." (Madrona, Jordán, & Barreto, 2008) 

The development of gross motor skills at an early age in children aged 3 to 6 years involves the movement of the long muscles of their body, increases the awareness of their muscular activity such as running, jumping, promotes the development of the vestibular nervous system, as well as their confidence and the control of their space environment. 

Among the methods of teaching and learning for this age range is ludic learning as the methods: Personalized education, Agazzi that focuses on the development of sight, the Fröebeliano contributes to the development for hearing and hearing, while the Montessori it is oriented to postural control and balance, the same ones that have the main characteristic of the game, since it generates in them a better use of their emotions and behaviors, reducing their stress and becoming an incentive to learn. 

According to (Piaget & Inhelder, 1997) "Knowledge is not obtained from the objects but from the actions that are performed on the objects", consequently, the application of playful methods of teaching and learning through the use of technology, such as electronic devices and ICTs aims to achieve that goal. 

In this context, the implementation of electronic devices including electronic prototypes as resources that facilitate ludic learning and teaching, aims to contribute to the significant benefits of traditional teaching. 

This study is descriptive, it covers the main approaches in the aspect of play methods and their application, as well as the results of these proposals, in order to be a base material or reference for future research in the area.},

El presente trabajo destacó la importancia de gestionar, optimizar los recursos y performance de las WLANs unificadas, con el objetivo principal de potenciar el acceso a la información de los diferentes entes del quehacer diario tanto para instituciones de carácter público o privado.

Inicialmente, el estándar que define las WLANs (IEEE 802.11) no consideraba mecanismos de calidad de servicio, pero a raíz de solventar las necesidades aparece la variante 802.11e para dar fin a los inconvenientes presentados en este tipo de infraestructuras debido a la evolución y convergencia de los servicios.

Abstract: 

 

This paper highlights the importance of managing, optimizing the resources and performance of unified WLANs. The main objective is related with the access to information of the different entities of the daily task both public or private institutions. Thereby, the current mobility and capacity needs of users require special attention for the strengthening of the wireless infrastructure and network resources translated into a provision of better quality services that can be enhanced through the analysis and implementation of WLAN QoS mechanisms, without leaving aside the consideration of design, planning and robust technology which are able to satisfy the current demand of critical applications in real time. 

 

Initially, the standard that defines the WLANs (IEEE 802.11) did not consider quality of service mechanisms, but as a result of solving the needs, the 802.11e variant appears to put an end to the inconveniences presented in this type of infrastructure due to the evolution and convergence of services. That is why this study aims to publicize the fundamental guidelines and recommendations for the deployment of Quality of Service in local area wireless networks.},

abstract = {Dimensionality reduction (DR) methods are able to produce low-dimensional representations of an input data sets which may become intelligible for human perception. Nonetheless, most existing DR approaches lack the ability to naturally provide the users with the faculty of controlability and interactivity. In this connection, data visualization (DataVis) results in an ideal complement. This work presents an integration of DR and DataVis through a new approach for data visualization based on a mixture of DR resultant representations while using visualization principle. Particularly, the mixture is done through a weighted sum, whose weighting factors are defined by the user through a novel interface. The interface's concept relies on the combination of the color-based and geometrical perception in a circular framework so that the users may have a at hand several indicators (shape, color, surface size) to make a decision on a specific data representation. Besides, pairwise similarities are plotted as a non-weighted graph to include a graphic notion of the structure of input data. Therefore, the proposed visualization approach enables the user to interactively combine DR methods, while providing information about the structure of original data, making then the selection of a DR scheme more intuitive.},

abstract = {The present work presents an analysis of the neighborhood criterion for the prototype selection (PS) in supervised machine learning classification algorithms. To do this, we use the condensed neighbor algorithm CNN to eliminate redundant data with the normalization of the distance to the centroid of each data subset criterion. This is done, in order to obtain the training matrix of the most optimal model. A selection of neighborhood criterion has been created from the quantification of the balance between the performance of the classification and the reduction of data set (CER). As proof of the test, we performed: (i) CER and (ii) real-time tests with the implementation of the algorithm within the WSN. The result is a data reduction of up to 88 % and a performance of the kNN classifier of 75%. It is concluded that the criterion of neighborhood with normalized distance must be less than or equal to 0.2 and the implementation of kNN with k = 1 obtains the best CER.},

abstract = {In the present investigation an electronic safety system is developed for babies in the stage of crawling, in order to alert a possible accident to the people who are in charge of their care in areas considered risky. The intelligent textile is integrated in a garment type harness that is connected to a crawling knee pads containing Magnetic Reed sensors, these are responsible for detecting the magnetic tapes previously placed in sites considered dangerous. These areas are chosen by quantifying the distance of the baby relative to its crawling speed; if the infant is in a possible accident zone, the system sends alert messages via an IoT platform. As a result of the system there is an average reaction time of 7.6 seconds with an average current consumption of 90 mA every approximately 12 seconds.},

abstract = {This work explores novel alternatives to conventional linear homotopy to enhance the quality of resulting transitions from object deformation applications. Studied/introduced approaches extend the linear mapping to other representations that provides smooth transitions when deforming objects while homotopy conditions are fulfilled. Such homotopy approaches are based on transcendental functions (TFH) in both simple and parametric versions. As well, we propose a variant of an existing quality indicator based on the ratio between the coefficients curve of resultant homotopy and that of a less-realistic, reference homotopy. Experimental results depict the effect of proposed TFH approaches regarding its usability and benefit for interpolating images formed by homotopic objects with smooth changes.},

abstract = {This work presents a comparative study of prototype selection (PS) algorithms. Such a study is done over data-from-sensor acquired by an embedded system. Particularly, five flexometers are used as sensors, which are located inside a glove aimed to read sign language. Measures were taken to quantify the balance between classification performance and reduction training set data (QCR) with k neighbors equal to 3 and 1 to force the classifier (kNN) to the maximum. Two tests were used: (a)the QCR performance and (b) the embedded system decision in real proves. As result the Random Mutation Hill Climbing (RMHC) algorithm is considered the best option to choose in this data type with removed instances at 87% and classification performance at 82% in software tests, also the classifier kNN must be with k=3 to improve the classification performance. In a real situation, with the algorithm implemented. The system makes correct decisions at 81% with 5 persons doing sign language in real time.},
