Ocnos : revista de estudios sobre lectura
2014
Este artículo documenta los espacios virtuales que congregan diariamente a cientos de adolescentes y jóvenes entre 13 y 29 años para hablar de libros, lectura y de autores. En estos espacios intercambian lecturas, reseñan sus relatos preferidos en sus blogs, debaten sobre si el narrador es adecuado para la narración o se quejan de cómo se trata la lectura en la escuela. La investigación se ha realizado a partir del estudio de dos casos: los foros de Laura Gallego y la campaña de promoción de venta del libro Delirium, de la Editorial SM, a través de los blogs administrados por los adolescentes y de las redes sociales Twitter y Facebook. Se han analizado 1.466 documentos de 452 sujetos para c…
La mesura de l'ús de les llengües en els mitjans telemàtics
2020
La consolidació de l'entorn digital i totes les seues modalitats de comunicació ha ampliat les possibilitats d'interacció i, per tant, els àmbits d'ús de les llengües. Com a adaptació a aquesta nova realitat, en aquesta aproximació metodològica plantegem la combinació de diferents tècniques no reactives: explotació de fonts secundàries, observació sistemàtica, i mystery shopping. Les fonts d'observació directa ens permeten mesurar de manera efectiva l'ús de les llengües en la comunicació telemàtica. Els autors ho han aplicat específicament en l'administració local i en empreses de serveis. En l'àmbit administratiu, a més, això ens ha servit per a desenvolupar un índex global de presència de…
A Coexistence Analysis of Blockchain, SCADA Systems, and OpenADR for Energy Services Provision
2022
The advent of blockchain technology allows the raise of new business models for the electricity market, opening the way also to end-users and letting them offer regulation services to the power grid. Thanks to the characteristic of being distributed, the blockchain technology could be a solution to balancing problems caused by the penetration of renewable sources, implementing a platform for Demand-Response programs delivery. Demand-Response allows consumers to respond to market signals by increasing or reducing their energy consumption, contributing to greater flexibility and stability of the grid and to a more efficient use of infrastructures and energy resources. Currently, Demand-Respon…
A Novel Approach for Faulty Sensor Detection and Data Correction in Wireless Sensor Network
2013
he main Wireless Sensor Networks purpose is represented by areas of interest monitoring. Even if the Wireless sensor network is properly initialized, errors can occur during its monitoring tasks. The present work describes an approach for detecting faulty sensors in Wireless Sensor Network and for correcting their corrupted data. The approach is based on the assumption that exist a spatio-temporal cross- correlations among sensors. Two sequential mathematical tools are used. The first stage is a probabilistic tools, namely Markov Random Field, for a two-fold sensor classification (working or damaged). The last stage is represented by the Locally Weighted Regression model, a learning techniq…
Relationships Between Social Support, Loneliness, and Internet Addiction in Chinese Postsecondary Students: A Longitudinal Cross-Lagged Analysis
2018
Using the Internet has become one of the most popular leisure activities among postsecondary students in China. Concern about the large number of students using the Internet has led to an increase in research on the influencing factors of Internet addiction and the negative consequences caused by it. This short-term longitudinal study examined the associations among three dimensions of social support [objective support (OS), subjective support (SS), and support utilization (SU)], loneliness, and the four dimensions of Internet addiction (compulsive Internet use [CIU] & withdrawal from Internet addiction [WIA], tolerance of Internet addiction [TIA], time-management problems [TMPs], and i…
Bērnu - vecāku attiecību kvalitāte saistībā ar bērna kompulsīvo interneta lietošanu longitudinālā skatījumā
2020
Maģistra darba mērķis bija noskaidrot bērnu un viņu vecāku savstarpējo attiecību kvalitāti, ņemot vērā vecāku novērtēto emocionālo siltumu kā audzināšanas pieju, un arī bērnu vērtējumu par attiecībām ar saviem vecākiem, kā tas ietekmē bērna kompulsīvo interneta lietošanas simptomu rādītājus pirmā un atkārtotā pētījuma mērījumos. Pētījums veikts pētniecības sadarbības projekta “Skolas vecuma bērnu interneta lietošana saistībā ar viņu socioemocionālo attīstību un vecāku audzināšanas pieejām Latvijā, Lietuvā un Taivānā: Longitudināls pētījums’’ ietvaros. Pētījumā piedalījās 263 otrās un trešās klases skolēni, vecumā no 8 līdz 10 gadiem, kuru vidējais vecums bija 8,6 gadi , un viens no bērna ve…
Performance evaluation of different techniques to estimate subjective quality in live video streaming applications over LTE-Advance mobile networks
2018
Abstract Current mobile service providers are offering Gigabit Internet access over LTE-Advanced networks. Traditional services, such as live video streaming, over wired networks are feasible on these networks. However different aspects should be taken into account due to the fast changing network conditions as well as the constrained resources of the mobile phones, in order to provide a good subjective video quality in terms of Mean Opinion Score (MOS). Our goal is to estimate and predict this subjective metric without information or reference from the original video, known as Non Reference approach. This approach is important for the Service Provider from a practical point of view, becaus…
MIME: A Mixed-Space Collaborative System with Three Immersion Levels and Multiple Users
2018
Shared spaces for remote collaboration are nowadays possible by considering a variety of users, devices, immersion systems, interaction capabilities, navigation paradigms, etc. There is a substantial amount of research done in this line, proposing different solutions. However, still a more general solution that considers the heterogeneity of the involved actors/items is lacking. In this paper, we present MIME, a mixed-space tri-collaborative system. Differently from other mixed-space systems, MIME considers three different types of users (in different locations) according to the level of immersion in the system, who can interact simultaneously – what we call a tri-collaboration. For the thr…
Carbon monoxide detection
2019
Carbon monoxide (CO) is a particularly toxic gas, and the CO poisoning is the leading cause of fatal poisoning in the world. One solution to deal with this dangerous gas is to exploit the advantages given to us by the applications and the technology advances in internet of things (IoT). In this context, we propose to integrate carbon monoxide detection objects to the internet, as part of civil protection intervention applications in case of detection of carbon monoxide to avoid poisoning. To do this, we propose a typical IoT architecture to manage the alerts sent to civil protection in the event of detection of carbon monoxide (CO). The architecture is based on the Message Queue Telemetry T…
Smart River : Towards Efficient Cooperative Autonomous Inland Navigation
2022
In recent years, inland waterway transport has witnessed increasing attention from France and many European countries. However, this mode of transport lacks flexibility, has an aging infrastructure, and the current ships are not adapted to an increase in transport capacity ensuring the safety of vessels and goods as well as reliable and constant delivery times. Therefore, inland transport must go through an organizational and technical renovation specific to its particular environment in order to hope to compete with land transport.In this thesis, we propose developing a smart river ecosystem that focuses on three principal axes: (i) automatic inland infrastructure, (ii) autonomous inland s…
