    Enabling the Automatic Generation of User Interfaces for Remote Laboratories

    Remote laboratories are an important component of blended and dis- tance science and engineering education. By definition, they provide access to a physical lab in a distant location. Many architectures enabling remote laboratory systems exist, the most common of which are Client-Server based. In this con- text, the Server interfaces the physical setup and makes it software-accessible. The Smart Device Specifications revisit a Client-Server architecture, with the main aim of cancelling the dependencies which inherently exist between a Client and a Server. This is done by describing the Server as a set of services, which are exposed as well-defined APIs. If a remote laboratory is built following the Smart Device Specifications, any person with programming skills can create a personalized client application to access the lab. But in practice, teachers rely on the mediated contact with a lab provider to have information about what kind of experiment(s) the lab in question implements. Even though there is a complete description of the available sensors and actuators making up a lab and how to be accessed, it is not clear how they are connected (relationships). In this sense, a list of sensors and actuators are not enough to make a guided selection of compo- nents to create the interface to an experiment. Therefore, the aim of this work is to support teachers in choosing the experiments and creating the respective UI on their own, in a pedagogically oriented scenario and by taking into consideration the target online learning environment. This is done by revisiting the Smart Device Specifications and extending them, in addition to proposing a tool that will automatically generate the user interface of the chosen experiment(s)

    CERN openlab Whitepaper on Future IT Challenges in Scientific Research

    Get PDF
    This whitepaper describes the major IT challenges in scientific research at CERN and several other European and international research laboratories and projects. Each challenge is exemplified through a set of concrete use cases drawn from the requirements of large-scale scientific programs. The paper is based on contributions from many researchers and IT experts of the participating laboratories and also input from the existing CERN openlab industrial sponsors. The views expressed in this document are those of the individual contributors and do not necessarily reflect the view of their organisations and/or affiliates

    Simplifying the OpenFlexure microscope software with the web of things.

    We present the OpenFlexure Microscope software stack which provides computer control of our open source motorised microscope. Our diverse community of users needs both graphical and script-based interfaces. We split the control code into client and server applications interfaced via a web API conforming to the W3C Web of Things standard. A graphical interface is viewed either in a web browser or in our cross-platform Electron application, and gives basic interactive control including common operations such as Z stack acquisition and tiled scanning. Automated control is possible from Python and Matlab, or any language that supports HTTP requests. Network control makes the software stack more robust, allows multiple microscopes to be controlled by one computer, and facilitates sharing of equipment. Graphical and script-based clients can run simultaneously, making it easier to monitor ongoing experiments. We have included an extension mechanism to add functionality, for example controlling additional hardware components or adding automation routines. Using a Web of Things approach has resulted in a user-friendly and extremely versatile software control solution for the OpenFlexure Microscope, and we believe this approach could be generalized in the future to make automated experiments involving several instruments much easier to implement

    CHORUS Deliverable 4.3: Report from CHORUS workshops on national initiatives and metadata

    Minutes of the following Workshops: • National Initiatives on Multimedia Content Description and Retrieval, Geneva, October 10th, 2007. • Metadata in Audio-Visual/Multimedia production and archiving, Munich, IRT, 21st – 22nd November 2007 Workshop in Geneva 10/10/2007 This highly successful workshop was organised in cooperation with the European Commission. The event brought together the technical, administrative and financial representatives of the various national initiatives, which have been established recently in some European countries to support research and technical development in the area of audio-visual content processing, indexing and searching for the next generation Internet using semantic technologies, and which may lead to an internet-based knowledge infrastructure. The objective of this workshop was to provide a platform for mutual information and exchange between these initiatives, the European Commission and the participants. Top speakers were present from each of the national initiatives. There was time for discussions with the audience and amongst the European National Initiatives. The challenges, communalities, difficulties, targeted/expected impact, success criteria, etc. were tackled. This workshop addressed how these national initiatives could work together and benefit from each other. Workshop in Munich 11/21-22/2007 Numerous EU and national research projects are working on the automatic or semi-automatic generation of descriptive and functional metadata derived from analysing audio-visual content. The owners of AV archives and production facilities are eagerly awaiting such methods which would help them to better exploit their assets.Hand in hand with the digitization of analogue archives and the archiving of digital AV material, metadatashould be generated on an as high semantic level as possible, preferably fully automatically. All users of metadata rely on a certain metadata model. All AV/multimedia search engines, developed or under current development, would have to respect some compatibility or compliance with the metadata models in use. The purpose of this workshop is to draw attention to the specific problem of metadata models in the context of (semi)-automatic multimedia search
