Open Apps: Opening Teaching Experiences and Applications

The Universitat Oberta de Catalunya (Open University of Catalonia, UOC) is an online university that makes extensive use of information and communication technologies to provide education. Ever since its establishment in 1995, the UOC has developed and tested methodologies and technological support services to meet the educational challenges posed by its student community and its teaching and management staff. The know-how it has acquired in doing so is the basis on which it has created the Open Apps platform, which is designed to provide access to open source technical applications, information on successful learning and teaching experiences, resources and other solutions, all in a single environment. Open Apps is an open, online catalogue, the content of which is available to all students for learning purposes, all IT professionals for downloading and all teachers for reusing. To contribute to the transfer of knowledge, experience and technology, each of the platform¿s apps comes with full documentation, plus information on cases in which it has been used and related tools. It is hoped that such transfer will lead to the growth of an external partner network, and that this, in turn, will result in improvements to the applications and teaching/learning practices, and in greater scope for collaboration. Open Apps is a strategic project that has arisen from the UOC's commitment to the open access movement and to giving knowledge and technology back to society, as well as its firm belief that sustainability depends on communities of interest.La Universitat Oberta de Catalunya (UOC) es una universidad en línea que realiza un uso intensivo de las tecnologías de la información y la comunicación para proporcionar una educación y aprendizaje a lo largo de la vida. Des de sus inicios la universidad ha desarrollado y testeado metodologías y tecnologías con el objetivo de proporcionar soluciones a los retos de aprendizaje y docentes ofrecidos por la comunidad de estudiantes, académicos y personal de gestión. Fundamentado en este saber hacer, nace la plataforma OpenApps con la finalidad principal de poner a disposición de la comunidad la experiencia acumulada en la UOC durante más de 15 años en docencia, aprendizaje y gestión para que pueda ser aplicado, adaptado o evolucionado por terceros. En este artículo se presentan las características esenciales para que una innovación pueda formar parte de esta plataforma institucional, las especificaciones y usuarios de la plataforma, la finalidad del servicio y las futuras líneas de trabajo.La universitat Oberta de Catalunya (UOC) és una universitat en línia que fa un ús intensiu de les tecnologies de la informació i la comunicació per proporcionar una educació i aprenentatge al llarg de la vida.

ParaFPGA 2011 : high performance computing with multiple FPGAs : design, methodology and applications

ParaFPGA 2011 marks the third mini-symposium devoted to the methodology, design and implementation of parallel applications using FPGAs. The focus of the contributions is mainly on organizing parallel applications in multiple FPGAs. This includes experiences from building a supercomputer with FPGAs, automatic and dedicated balancing of different tasks on heterogeneous FPGA constellations and designing optimal interconnects between collaborating FPGAs

Experiences in porting mini-applications to OpenACC and OpenMP on heterogeneous systems

This article studies mini-applications—Minisweep, GenASiS, GPP, and FF—that use computational methods commonly encountered in HPC. We have ported these applications to develop OpenACC and OpenMP versions, and evaluated their performance on Titan (Cray XK7 with K20x GPUs), Cori (Cray XC40 with Intel KNL), Summit (IBM AC922 with Volta GPUs), and Cori-GPU (Cray CS-Storm 500NX with Intel Skylake and Volta GPUs). Our goals are for these new ports to be useful to both application and compiler developers, to document and describe the lessons learned and the methodology to create optimized OpenMP and OpenACC versions, and to provide a description of possible migration paths between the two specifications. Cases where specific directives or code patterns result in improved performance for a given architecture are highlighted. We also include discussions of the functionality and maturity of the latest compilers available on the above platforms with respect to OpenACC or OpenMP implementations

Description and Experience of the Clinical Testbeds

This deliverable describes the up-to-date technical environment at three clinical testbed demonstrator sites of the 6WINIT Project, including the adapted clinical applications, project components and network transition technologies in use at these sites after 18 months of the Project. It also provides an interim description of early experiences with deployment and usage of these applications, components and technologies, and their clinical service impact

Implementing congestion control in the real world

It is well known that congestion control is a key issue for the safe deployment of multimedia applications over IP. We describe our initial experiences implementing TCP-friendly congestion control in a system designed to deliver HDTV content over IP networks. In particular we discuss the effects of packet reordering on the calculated throughput, and highlight the problems this can pose for high-rate applications

Auditing the ICT experiences of teacher education undergraduates

The importance of teacher education graduates having appropriate information and communication technology OCT) for learning competencies and experiences is well documented. However, without well developed processes for auditing the ICT experiences of undergraduates it should not be assumed that teachers enter their profession with the required ICT competencies to support their students' learning. This paper reports on the first phase of a project to audit the ICT experiences of teacher education undergraduates. It finds that the individual experiences of undergraduates can vary considerably depending on their choice of majors, electives or specialist teaching areas. It further finds that high percentages of students perceive themselves to have no competency with a range of ICT applications that would support the more motivational and interesting aspects of ICT integration for student learning

NASTRAN thermal analyzer status, experience, and new developments

TOBE: Tangible Out-of-Body Experience

We propose a toolkit for creating Tangible Out-of-Body Experiences: exposing the inner states of users using physiological signals such as heart rate or brain activity. Tobe can take the form of a tangible avatar displaying live physiological readings to reflect on ourselves and others. Such a toolkit could be used by researchers and designers to create a multitude of potential tangible applications, including (but not limited to) educational tools about Science Technologies Engineering and Mathematics (STEM) and cognitive science, medical applications or entertainment and social experiences with one or several users or Tobes involved. Through a co-design approach, we investigated how everyday people picture their physiology and we validated the acceptability of Tobe in a scientific museum. We also give a practical example where two users relax together, with insights on how Tobe helped them to synchronize their signals and share a moment
