Active learning in digital communications with low-cost software defined radio

2021

Las comunicaciones digitales se enseñan tradicionalmente en sesiones de laboratorio desde un punto de vista teórico, utilizando plataformas de simulación. Sin embargo, el sistema de Acreditación Académica incluye la dimensión de "lo que se espera que los estudiantes sean capaces de hacer", lo que plantea la necesidad de disminuir la brecha entre las sesiones de laboratorio simuladas y un enfoque más práctico y realista. En este trabajo, proponemos una metodología para mejorar el aprendizaje de los aspectos prácticos relacionados con los cursos de Comunicaciones Digitales, así como para aumentar la motivación de los estudiantes, mediante el uso de dispositivos de radio definida por software …

Smart Assistance for Students and People Living in a Campus

2019

Being part of one of the fastest growing area in Artificial Intelligence (AI), virtual assistants are nowadays part of everyone's life being integrated in almost every smart device. Alexa, Siri, Google Assistant, and Cortana are just few examples of the most famous ones. Beyond these off-the-shelf solutions, different technologies which allow to create custom assistants are available. IBM Watson, for instance, is one of the most widely-adopted question-answering framework both because of its simplicity and accessibility through public APIs. In this work, we present a virtual assistant that exploits the Watson technology to support students and staff of a smart campus at the University of Pa…

Analysis of contextual information sharing during table tennis matches: An empirical study on coordination in sports

2009

Abstract This study examined contextual information sharing between table tennis players during competitive interaction (two opponents during singles) and cooperative interaction (two partners during doubles) in a study based on the notion of shared context (Salembier & Zouinar, 2000) and conducted within the semiological framework of the course‐of‐action (Theureau, 2003). Matches were videotaped and players’ verbalizations as they viewed the tapes were collected a posteriori. The analysis and comparison of their courses of action served to characterize the nature and content of the contextual information that was shared between the players during singles and doubles matches. The results re…

Does Navigation Always Predict Performance? Effects of Navigation on Digital Reading are Moderated by Comprehension Skills

2016

<p align="left">This study investigated interactive effects of navigation and offline comprehension skill on digital reading performance. As indicators of navigation relevant page selection and irrelevant page selection were considered. In 533 Spanish high school students aged 11-17 positive effects of offline comprehension skill and relevant page selection on digital reading performance were found, while irrelevant page selection had a negative effect. In addition, an interaction between relevant page selection and offline comprehension skill was found. While the effect of relevant page selection was strong in good offline comprehenders, it was significantly reduced in weak offline c…

Interactive Uses of Journalism: Crossing Between Technological Potential and Young People’s News-Using Practices

2004

The article examines the interactive uses of journalism, focusing on the changes brought by new communication technology in the everyday news media uses of young Finns. The study is based on a survey and in-depth interviews. The results indicate that even though young Finns have easy access to new communication technology, journalism is still predominantly used via television and printed newspapers. While nearly all subjects followed news regularly, a fifth of the respondents had taken advantage of participatory activities offered by the news media. Consequently, technology alone does not seem to alter news practices. The interactive usage of journalism thus seems to be individualized ente…

Les jeux vidéo comme instruments de techno-transe

2016

International audience; This article aims to reopen the genealogy of video games, studying the similarities they share with what the author calls ‘techno-trance devices’. These devices, which are contemporary to the first video games in the early 1960s, rely on the creative hijacking of laboratory instruments. They share numerous technical and media properties with video games. Moreover, there are some records of these techno-trance devices being used during religious practices at the time, which might lead to speculation of a latent trance influence in video games as apparatuses. These shared properties between video games and these devices, derived from counterculture, are thus studied th…

Organizing a sonic space through vocal imitations

2016

A two-dimensional space is proposed for exploration and interactive design in the sonic space of a sound model. A number of reference items, positioned as landmarks in the space, contain both a synthetic sound and its vocal imitation, and the space is geometrically arranged based on the acoustic features of these imitations. The designer may specify new points in the space either by geometric interpolation or by direct vocalization. In order to understand how the vast and complex space of the human voice could be organized in two dimensions, we collected a database of short excerpts of vocal imitations. By clustering the sound samples on a space whose dimensionality has been reduced to the …

On the relevance of script writing basics in audiovisual translation practice and training

2012

Audiovisual texts possess characteristics that clearly differentiate audiovisual translation from both oral and written translation, and prospective screen translators are usually taught about the issues that typically arise in audiovisual translation. This article argues for the development of an interdisciplinary approach that brings together Translation Studies and Film Studies, which would prepare future audiovisual translators to work with the nature and structure of a script in mind, in addition to the study of common and diverse translational aspects. Focusing on film, the article briefly discusses the nature and structure of scripts, and identifies key points in the development and …
