A Teledentistry system for the second opinion
2014
In this paper we present a Teledentistry system aimed to the Second Opinion task. It make use of a particular camera called intra-oral camera, also called dental camera, in order to perform the photo shooting and real-time video of the inner part of the mouth. The pictures acquired by the Operator with such a device are sent to the Oral Medicine Expert (OME) by means of a current File Transfer Protocol (FTP) service and the real-time video is channeled into a video streaming thanks to the VideoLan client/server (VLC) application. It is composed by a HTML5 web-pages generated by PHP and allows to perform the Second Opinion both when Operator and OME are logged and when one of them is offline.
Teleradiologie nach Röntgenverordnung - beispielhafte Anwendung der Open-Source-Software SecTelMed
2005
Purpose: Establishing a teleradiology connection according to the Rontgenverordnung (RoV) between a peripheral hospital and a university clinic will contribute to improve the radiological emergency treatment on weekends, holidays and at night. It will also better the medical care for patients and help to lower the costs. Materials and Methods: By using the open source software SecTelMed, the radiological picture is transferred via an internet-linked SSH communication server. The integration of the teleradiological data transfer into the actual workflow is attained by using the already existing PACS infrastructure. While its installation is still under construction, it is actually employed f…
The EU-project United4Health: User-centred design of an information system for a Norwegian telemedicine service.
2015
Introduction Organizational changes of health care services in Norway brought to light a need for new clinical pathways. This study presents the design and evaluation of an information system for a new telemedicine service for chronic obstructive pulmonary disease patients after hospital discharge. Methods A user-centred design approach was employed composed of a workshop with end-users, two user tests and a field trial. For data collection, qualitative methods such as observations, semi-structured interviews and a questionnaire were used. Results User workshop’s outcome informed the implementation of the system initial prototype, evaluated by end-users in a usability laboratory. Several us…
Range-based versus automated markerless image-based techniques for rock art documentation
2014
Nowadays there is a huge proliferation of fully automatic image-based solutions producing either three-dimensional (3D) point clouds or 3D models. However, the reliability of the output is not usually reported and clarified. This paper presents a comparison of the 3D modelling results achieved on two rock art shelters at separate archaeological sites using a high-resolution digital camera. The 3D point clouds were produced using automatic image-based photogrammetric and computer vision software running either locally (FOTOGIFLE and VisualSFM) or through a webbased reconstruction service (Autodesk 123D Catch). The first two automatic approaches are compared with a manual bundle block adjustm…
Movie Script Similarity Using Multilayer Network Portrait Divergence
2020
International audience; This paper addresses the question of movie similarity through multilayer graph similarity measures. Recent work has shown how to construct multilayer networks using movie scripts, and how they capture different aspects of the stories. Based on this modeling, we propose to rely on the multilayer structure and compute different similarities, so we may compare movies, not from their visual content, summary, or actors, but actually from their own storyboard. We propose to do so using “portrait divergence”, which has been recently introduced to compute graph distances from summarizing graph characteristics. We illustrate our approach on the series of six Star Wars movies.
How Do Computer Science Students Use Distributed Version Control Systems?
2013
The inclusion of version control systems into computing curricula enables educators to promote competences needed in real-life situations. The use of a version control system also has several potential benefits for the teacher. The teacher might, for instance, use the tool to monitor students’ progress and to give feedback efficiently. This study analyzes how students used the distributed version control system Git in several computing courses. We analyzed students’ commit log data in two advanced programming courses, a second-year introductory software engineering course, and two courses where students developed software products. This enables us to compare Git usage between introductory l…
Evaluation of an Educational Video Production Environment
2019
In this paper, a cloud-based solution for the easy production and meaningful distribution of video-based learning material is presented and evaluated. Using this system, lecturers can produce video material with their own computers anywhere, at any time. The system enables the production of longer lecture videos as well as short videos, each containing only one of the course's topics. The system also handles video sharing for students automatically in a meaningful way through the course's table of contents. An evaluation of the first production version of the video production and distribution system was carried out by collecting qualitative material from the lecturers and students.
An Augmented Campus Design for Context-aware Service Provision
2005
This paper deals with the design of a multi-modal system for pervasive context-aware service provision and human-environment interaction in augmented environments by the use of Personal Digital Assistants (PDA) or SmartPhones. The system enables mobile devices and remote displays to perform as interaction devices with pervasive applications which run on a dynamically composed server network. Visual interaction for service setup and provision are driven by appropriate graphical interfaces and XML-based protocols, which are dynamically composed according to the type of service and to the user current position by means of a mobile agent-based framework. The paper discusses both protocols, hard…
Protocolo técnico para la fotografía de fuentes filológicas primarias
2014
con fines documentales, proyectado para garantizar la máxima fidelidad posible al motivo original representado. Tras una descripción detallada del material necesario, seleccionado específicamente en función de las necesidades particulares de la fotografía de textos manuscritos o impresos, se desarrolla un procedimiento adaptado a las nuevas circunstancias de la fotografía digital, concebido en dos fases: la captación de la imagen en formato RAW, y su posterior edición. En este estudio se trata la primera parte, describiendo sistemáticamente, paso a paso, las decisiones técnicas relativas a los ajustes fotográficos de la toma en diferentes situaciones lumínicas, encaminadas a maximizar la ca…
Los cuentos de los hermanos Grimm en el contexto multimedia del siglo XXI
2014
El análisis de obras cinematográficas y material multimedia se está convirtiendo en una de las herramientas más de moda y útiles en los estudios literarios. Precisamente los Kinder- und Hausmärchen de los hermanos Grimm han sido de los textos que más transformaciones ha sufrido, en especial, gracias a las nuevas tecnologías. Así encontramos no sólo nuevas adaptaciones, versiones y perversiones, tanto literarias como fílmicas, de los más conocidos cuentos populares, sino también experimentos virtuales, interactivos y lingüísticos que obligan a replantear constantemente las fronteras de un género que no deja de evolucionar. El objeto de la presente comunicación será, por lo tanto, mostrar nue…
