Research Software Sustainability: Report on Knowledge Exchange Workshop

The report introduces software sustainability, provides definitions, clearly demonstrates that software is not the same as data and illustrates aspects of sustainability in the software lifecycle. The recommendations state that improving software sustainability requires a number of changes: some technical and others societal, some small and others significant. We must start by raising awareness of researchers’ reliance on software. This goal will become easier if we recognise the valuable contribution that software makes to research – and reward those people who invest their time into developing reliable and reproducible software. The adoption of software has led to significant advances in research. But if we do not change our research practices, the continued rise in software use will be accompanied by a rise in retractions. Ultimately, anyone who is concerned about the reliability and reproducibility of research should be concerned about software sustainability. Beside highlighting the benefits of software sustainability and addressing the societal and technical barriers to software sustainability, the report provides access to expertise in software sustainability and outlines the role of funders. The report concludes with a short landscape of national activities in Europe and outside Europe. As a result of the workshop steps will be explored to establish European coordination and cooperation of national initiatives.

Cine Digital y sus Contenedores. Herramientas de Software libre basadas en las Especificaciones DCI

El Cine Digital es aquel que utiliza la tecnología digital para grabar, distribuir y proyectar películas. En los años 90, el cine comenzó un proceso de transición, del soporte fílmico a la tecnología digital. Pero el salto definitivo se dio con las grandes superproducciones de principios del 2000. Con este cambio de era y debido a la rápida difusión del digital y la proliferación de formatos se creo el DCI (Digital Cinema Initiative), para cambiar el modo en que las personas consumen cine. Trabajando junto con los miembros del comité SMPTE (Organización americana encargada de crear los estándares de la industria audiovisual formada por ingenieros, técnicos y fabricantes) publicó un sistema de especificaciones que han adoptado las mayores productoras estadounidenses. Mediante este acuerdo, aseguraban la calidad técnica de las producciones, la compatibilidad entre sistemas y como no, su hegemonía particular. Entre las especificaciones técnicas que suscribieron que son la base actual del DCI figuran la resolución de fotograma, el espacio de color, la compresión de imagen, la encriptación y el método de empaquetado de archivos. Y hoy en día son un estándar en la masterización, distribución y en la proyección final en las salas de cine. Una de las grandes esperanzas que hay puestas en la tecnología digital es la democratización en el mundo del cine y la supuesta abolición de las barreras económicas a la hora de realizar películas, dado lo barato que puede resultar la grabación digital y la posibilidad de pasar el material a video y editarlo en un ordenador domestico. Independientemente de los sistemas de edición que se utilicen, el formato de archivo o incluso el códec usado, los servidores de cine digital solo aceptan un tipo de archivo llamado DCP (Digital Cinema Package). Hay que aclarar que el DCP es abierto, documentado y que esta basado en los estándares SMPTE. Por lo tanto, existen en el mercado actual herramientas de software libre que permiten crear un DCP válido según las normas del DCI y compatible con los actuales servidores de cine digital. El propósito de este proyecto principalmente es documentar desde un punto de vista técnico la creación de un archivo DCP y analizar las diferentes herramientas existentes en el mercado para poder realizarlo: tanto las de uso comercial, como las de software libre. Como base se partirá de las aplicaciones creadas por la empresa alemana Fraunhofer (EasyDCP Creator, Player) - es el software utilizado en el estudio REC - y de otras herramientas más rudimentarias y escritas en C++ como (asdcplib) de Cinecert.

Reuse of software components orientated to iOS mobile devices

Within the next few pages, I will try to give a wide description of the project that I have been doing for IK4-Ikerlan. For the last six months, I have been working in developing a socket-based application for Apple devices. These devices work under the iOS operative system, which is programmed in Objective-C, a language similar to C. Although I did not have the chance to develop this application for Apple TV, I was able to create an application for iPhone and another one for iPad. The only difference between both applications was the screen resolution, but we decided to make them separately, as it would be really hard to combine both resolutions, and wallpapers, everything in the same workspace. Finally, it is necessary to add that the main goal was not to create a new application for iOS, but to translate an Android application into iOS. To achieve this, it is required to translate Java code into Objective- C, which is the language used to develop applications for all kinds of Apple devices. Fortunately, there is a tool created by Google, which helped us with this exercise. This tool is called j2ObjC, and it is still being developed.

Software de control desarrollado en ROS para teleoperar de manera eficiente el robot Kuka Lightweight mediante el háptico Phantom Omni

La teleoperación o telerobótica es un campo de la robótica que se basa en el control remoto de robots esclavo por parte de un usuario encargado de gobernar, mediante un dispositivo maestro, la fuerza y movimiento del robot. Sobre dicho usuario recaen también las tareas de percepción del entorno, planificación y manipulación compleja. Concretamente se pretende desarrollar el control software necesario para teleoperar un manipulador esclavo, Kuka Lightweigh mediante un dispositivo háptico Phamton Omni, que se comporta como maestro, sin que afecten las diferencias dinámicas y estructurales existentes entre ambos dispositivos, aportando información adicional al operador para facilitar la operación. La principal motivación de la evolución de esta tecnología se debe a la necesidad de realizar trabajos en entornos hostiles, de difícil acceso, o perjudiciales para la salud del usuario.

The lowland dry zone of Sri Lanka: site for study of aquaculture development within farmer-managed irrigation systems and methodology for participatory situation appraisal

The aims of this paper are twofold. Firstly to characterise rural poverty and to give a broad overview of the agro-ecological, climatic and socio-economic conditions in Sri Lanka which shape poverty. Secondly to present the methodology employed to screen suitable field research areas and the techniques subsequently used to carry out Rapid Rural Appraisal in two upper-watersheds villages. Also presented are details of a concurrent stakeholder analysis that aimed to investigate the capacity of secondary stakeholders to promote sustainable aquatic resource development and to invite their participation in the formulation of a participatory research agenda.[PDF contains 58 pages]

The IRYSS-COPD appropriateness study: objectives, methodology, and description of the prospective cohort

Background: Patients with chronic obstructive pulmonary disease (COPD) often experience exacerbations of the disease that require hospitalization. Current guidelines offer little guidance for identifying patients whose clinical situation is appropriate for admission to the hospital, and properly developed and validated severity scores for COPD exacerbations are lacking. To address these important gaps in clinical care, we created the IRYSS-COPD Appropriateness Study. Methods/Design: The RAND/UCLA Appropriateness Methodology was used to identify appropriate and inappropriate scenarios for hospital admission for patients experiencing COPD exacerbations. These scenarios were then applied to a prospective cohort of patients attending the emergency departments (ED) of 16 participating hospitals. Information was recorded during the time the patient was evaluated in the ED, at the time a decision was made to admit the patient to the hospital or discharge home, and during follow-up after admission or discharge home. While complete data were generally available at the time of ED admission, data were often missing at the time of decision making. Predefined assumptions were used to impute much of the missing data. Discussion: The IRYSS-COPD Appropriateness Study will validate the appropriateness criteria developed by the RAND/UCLA Appropriateness Methodology and thus better delineate the requirements for admission or discharge of patients experiencing exacerbations of COPD. The study will also provide a better understanding of the determinants of outcomes of COPD exacerbations, and evaluate the equity and variability in access and outcomes in these patients.
