Streaming era digital media piracy : an integration of three theoretical perspectives
2018
Consumer digital piracy in media contexts is one of the most publicized adverse developments brought on by the Internet and digitization of data. Since the turn of the millennium, it has irrevocably changed the business environment for the creative industries. The sharp decrease of recorded music sales, especially in the physical album format, is perhaps the best example of the negative effects digital piracy. However, the growth of legal services in digital music and video is balancing this trend, as consumers have found that piracy is no longer the obvious solution to acquiring music and video content. This also calls for new approaches to piracy research. We sought them by integrating th…
¿Pueden los juegos mejorar la habilidad lectora?
2017
Investigaciones recientes han mostrado que las habilidades lectoras pueden ser moduladas mediante el entrenamiento en juegos/videojuegos. Dado que un déficit en atención visual puede ser causante de la dislexia, el entrenamiento en videojuegos puede mejorar la atención visual, lo cual puede ayudar al tratamiento de la dislexia. Pero también un juego de mesa como es el Scrabble puede mejorar las habilidades lectoras: los jugadores expertos de Scrabble tienen unas destrezas ortográfico-léxicas más eficientes que los no expertos. Trabajos futuros han de centrarse en examinar qué beneficios aporta el entrenamiento mediante juegos/videojuegos en la mejora del aprendizaje lector.
A Dataset of Annotated Omnidirectional Videos for Distancing Applications
2021
Omnidirectional (or 360°) cameras are acquisition devices that, in the next few years, could have a big impact on video surveillance applications, research, and industry, as they can record a spherical view of a whole environment from every perspective. This paper presents two new contributions to the research community: the CVIP360 dataset, an annotated dataset of 360° videos for distancing applications, and a new method to estimate the distances of objects in a scene from a single 360° image. The CVIP360 dataset includes 16 videos acquired outdoors and indoors, annotated by adding information about the pedestrians in the scene (bounding boxes) and the distances to the camera of some point…
Clinical evaluation of automated capillary refill time estimation in dogs and cats
2019
In this study, we clinically evaluated a pulse oximeter-based device for automated capillary refill time (CRT) estimation in dogs and cats. CRT can reveal conditions like shock or anemia in dogs and cats. However, visual CRT estimation has low repeatability, and the available optical systems for automated estimation are not suitable for pets. We evaluated a custom-made portable CRT measuring device on various measurement sites of 12 dogs and 11 cats with parallel visual CRT estimation on the gum by treating veterinarian. The capillary refill was also recorded by a video camera for reference. The visual and video procedures were moderately correlated with the coefficient of 0.61; visual CRT …
Attēlu semantiskā segmentācija izmantojot dziļuma kartes
2019
Šī maģistra darba mērķis ir izpētīt esošos attēlu semantiskās segmentācijas risinājumus un izpētīt dziļuma karšu ietekmi uz attēla semantisko segmentāciju. Darbā ir aprakstīti veidi kā iegūt dziļuma kartes gan no sensoriem, gan arī no pieejamām RGB attēlu kamerām, no kurām var dabūt augstas izšķirtspējas attēlus un līdz ar to arī augstas izšķirtspējas dziļuma kartes. Apskatītas ir arī semantiskās segmentācijas populārākās metodes un principi labākai segmentācijai. Kā arī kvalitātes mēri, lai novērtētu segmentācijas efektivitāti.

Metodologies competencials en la formació literària de mestres: experiències didàctiques per fomentar el pensament reflexiu: Competence-based methodo…
2023
L’objectiu d’aquest article és descriure i analitzar alguns projectes d’educació literària realitzats durant els últims vuit anys en el marc de la formació de docents per tal de reflexionar sobre la importància de l’ús de metodologies actives i competencials per l’ensenyament de la literatura al context universitari. Aquests projectes conformen experiències didàctiques com ara tallers d’escriptura, rutes literàries i l’ús dels videojocs per al foment lector. Presentem un comentari qualitatiu dels resultats d’aprenentatge més significatius i de la valoració dels estudiants a partir de la tria de diverses mostres. Finalment, arribem a la conclusió que aquestes experiències promouen no només l…
Models of the population playing the Rock-Paper-Scissors game
2018
We consider discrete dynamical systems coming from the models of evolution of populations playing rock - paper - scissors game . Asymptotic behaviour of trajectories of these systems is described, occurrence of the Neimark-Sacker bifurcation and nonexistence of time averages are proved.
Population and Query Interface for a Content-Based Video Database
2002
In this paper we describe the first full implementation of a content-based indexing and retrieval system for MPEG-2 and MPEG-4 videos. We consider a video as a collection of spatiotemporal segments called video objects; each video object is a sequence of video object planes. A set of representative video object planes is used to index each video object. During the database population, the operator, using a semi-automatic outlining tool we developed, manually selects video objects and insert some semantical information. Low-level visual features like color, texture, motion and geometry are automatically computed. The system has been implemented on a commercial relational DBMS and is based on…
Autism spectrum disorders and anxiety: measurement and treatment
2021
Abstract Autism spectrum disorders (ASDs) are a group of neurodevelopmental disorders that have, in common, deficits in communication and social interaction and present repetitive behaviors and restricted interests. There is a great variability of symptoms associated with ASD. Among them, anxiety disorders are perhaps one of the most frequent and most developmentally disruptive in children, youths, and adults, which generate alterations in family life also. The treatments based on cognitive–behavioral therapy (CBT) have the highest scientific evidence. In a population with ASD, both program adaptations and specific programs have been developed. Due to its characteristics, the most studied p…
