Video Viewing Patterns Using Different Teaching Treatments: A Case Study Using YouTube Analytics
2019
Aquest estudi explora els patrons de visualització de 17 vídeos en un context tradicional daprenentatge i en un context de classe invertida per 723 estudiants de negocis cursant un mòdul relacionat amb . Mentre recerques anteriors s?han centrat principalment en resultats (per exemple, satisfacció/resultats dels alumnes), en aquest estudi l?enfocament recau en com la natura de les interaccions del estudiants amb el vídeos por determinar-se mitjançant un anàlisi profund de les dades analítiques. Els nostres resultats mostren menys interacció amb els vídeos en el context de la classe invertida que en el de la classe tradicional. De la mateixa manera, mostren un ús més elevat dels vídeos com a …
Distributed Clustering Algorithm for Spatial Field Reconstruction in Wireless Sensor Networks
2015
En este trabajo, consideramos el problema de la estimación espacial distribuida para la reconstrucción del campo radio en redes de sensores inalámbricos. Para estimar el campo, se utiliza una técnica geoestadística llamada kriging. La estimación espacial centralizada con un gran número de sensores conllevan un elevado coste computacional y gasto de energía. Presentamos un novedoso algoritmo de clustering distribuido para estimar mapas de interferencia espacial, que son esenciales para las operaciones y la gestión de las futuras redes inalámbricas. En este algoritmo, los clústeres de sensores se forman de forma adaptativa mediante la minimización de la varianza de kriging. El cálculo del sem…
Comparative Analysis of Machine Learning Methods to Predict Growth of F. sporotrichioides and Production of T-2 and HT-2 Toxins in Treatments with Et…
2021
The efficacy of ethylene-vinyl alcohol copolymer films (EVOH) incorporating the essential oil components cinnamaldehyde (CINHO), citral (CIT), isoeugenol (IEG), or linalool (LIN) to control growth rate (GR) and production of T-2 and HT-2 toxins by Fusarium sporotrichioides cultured on oat grains under different temperature (28, 20, and 15 °C) and water activity (aw) (0.99 and 0.96) regimes was assayed. GR in controls/treatments usually increased with increasing temperature, regardless of aw, but no significant differences concerning aw were found. Toxin production decreased with increasing temperature. The effectiveness of films to control fungal GR and toxin production was as follows: EVOH…
A naive approach to compose aerial images in a mosaic fashion
2002
There is growing interest in multiple sequence image analysis to represent those data in a new landscape, for instance reconstruction of old films, mosaicing of images. This paper focuses attention on the mosaic problem; it introduces a naive method to link together images where a common part of the scene is present among two images. An application has been developed to test the method on aerial sequences of images. Given the long distance of aircraft from the scene, the method assumes images without distortions and without problems of prospective. Moreover, the application does not need any additional parameters coming from human experience and for this reason it can be thought of as a ful…
Integrating the Real and Virtual World for Academic Language Education in Second Life
2013
This chapter focuses on a Second Language Acquisition (SLA) study conducted in virtual worlds that could help teachers in terms of knowledge about acquisition processes, in which technology is integration between formal and non formal education. The research comprises of two studies strongly focused on the development of Italian oral language proficiency. It was held within Second Life® (SL™)1 in order to explore the affordances of public spaces to enhance Intercultural Communicative Competence (ICC)2 and to stimulate the oral production through learner’s engagement. Since 2007, a new pilot project, Café Italia, was developed by Carmela Dell’Aria (aka Misy Ferraris) in Second Life®. Startin…
gNOMO: a multi-omics pipeline for integrated host and microbiome analysis of non-model organisms
2020
The study of bacterial symbioses has grown exponentially in the recent past. However, existing bioinformatic workflows of microbiome data analysis do commonly not integrate multiple meta-omics levels and are mainly geared toward human microbiomes. Microbiota are better understood when analyzed in their biological context; that is together with their host or environment. Nevertheless, this is a limitation when studying non-model organisms mainly due to the lack of well-annotated sequence references. Here, we present gNOMO, a bioinformatic pipeline that is specifically designed to process and analyze non-model organism samples of up to three meta-omics levels: metagenomics, metatranscriptomic…
Museos para todos: la traducción e interpretación para entornos multimodales como herramienta de accesibilidad universal
2012
This article is the English version of “Museos para todos. La traducción e interpretación para entornos multimodales como herramienta de accesibilidad universal” by Catalina Jiménez Hurtado, Claudia Seibel & Silvia Soler Gallego. It was not published on the print version of MonTI for reasons of space. The online version of MonTI does not suffer from these limitations, and this is our way of promoting plurilingualism. Audiovisual Translation (AVT) has a scientific responsibility to develop analytical methodologies for the textual phenomenon of multimodality, and for the translation strategies associated with it. At the same time, it should aim to provide studies of universal accessibility wi…
Subjective Evaluation of Video on Demand Systems Using Different Network Connections
2009
Nowadays, society makes use of new technologies as they appear. Due to this boom, the use of resources via web is increasing notably. In of training and education cases, companies such as universities are offering tele-learning platforms to complement and facilitate the learning process. Some of these called e-learning platforms can have explanatory videos as a resource for training. For the codification of these videos, we have to use parameters which provide a trade-off between the video sizes to be transmitted that optimize bandwidth and video and audio quality. This paper presents a subjective study of the video quality on transmission depending on the types of users’ network access to …
Cloud-based eHealth video encoding system for real time thermographic streaming: Performance evaluation
2017
Recent studies about the use of cloud platforms indicate that more than three-fourths of healthcare institutions apply these technologies in their daily lives. However, in most cases the cloud is based on “Infrastructure as a Service”, instead of developing new applications using the benefits that can bring us this type of technology. For these reasons, this paper shows a private cloud-based system to provide a new application based on thermographic video streaming. In this case, the cloud architecture is divided into three zones. The first zone is where the patient is under medical supervision through body temperature analysis using a global thermal camera. The second zone is the cloud its…
Phone-Controlled Delivery of NGN Services into Residential Environments
2008
The horizontally layered architecture of the IMS/NGN standards family enables the delivery of services independent of access network and requesting device. In this article, the authors propose a further separation of service control and delivery, allowing the requesting device - in particular a user's mobile phone - to invite other devices (we will focus on DLNA appliances) into the service delivery, enhancing both user experience and service design flexibility. The proposed solution builds on exploiting proximity technologies (e.g. barcodes, NFC) for pairing the control device with a remote environment. Motivated by scenarios, the architecture concepts are explained and a prototype that wa…
