    The future Internet is expected to be composed of a mesh of interoperable web services accessible from all over the web. This approach has not yet caught on since global user?service interaction is still an open issue. This paper states one vision with regard to next-generation front-end Web 2.0 technology that will enable integrated access to services, contents and things in the future Internet. In this paper, we illustrate how front-ends that wrap traditional services and resources can be tailored to the needs of end users, converting end users into prosumers (creators and consumers of service-based applications). To do this, we propose an architecture that end users without programming skills can use to create front-ends, consult catalogues of resources tailored to their needs, easily integrate and coordinate front-ends and create composite applications to orchestrate services in their back-end. The paper includes a case study illustrating that current user-centred web development tools are at a very early stage of evolution. We provide statistical data on how the proposed architecture improves these tools. This paper is based on research conducted by the Service Front End (SFE) Open Alliance initiative

    Cost-effective HPC clustering for computer vision applications

    Get PDF
    We will present a cost-effective and flexible realization of high performance computing (HPC) clustering and its potential in solving computationally intensive problems in computer vision. The featured software foundation to support the parallel programming is the GNU parallel Knoppix package with message passing interface (MPI) based Octave, Python and C interface capabilities. The implementation is especially of interest in applications where the main objective is to reuse the existing hardware infrastructure and to maintain the overall budget cost. We will present the benchmark results and compare and contrast the performances of Octave and MATLAB

    Purpose Course reserve module in ILS OPAC and web-scale library discovery services are interconnected to data management and educational resource management systems. Every department and course instructor are designed the course based on the user\u27s requirements. The goal of this article is to analyze the instructional reserves component integrating open source tools Koha and VuFind in order to provide advanced level CMS and LCMS services that satisfy users. . It is also feasible with metadata searching from other repositories, e.g., OCLC WorldCat and Amazon, to increase the web-scale discovery services among the users and library professionals. Methodology Popular level software has been selected based on course reserve requirements such as Koha and VuFind. It needs proper installation and configuration with the help of multiple files and scripts. Design the template and layout based on Koha and VuFind for course-specific reserve and add the barcode to display the items and link in Koha library OPAC easily. This course module will be integrated with the VuFind to provide web-enabled discovery services based on departments, instructors, and course URLs. Findings The whole integrated domain-specific interface is beneficial to the users because they could easily access the course reserve materials developed by different subject experts. As a consequence, both Koha and VuFind just provide capability of delivering the appropriate course module to the correct participants at the perfect time.Library users have access and download their course from this integrated interface to continue their online learning process. This framework will fully enable web-based services for CMS and LCMS regarding the fulfillment of tags clouds, metadata searching, and OCLC WorldCat Local searching. Originality This innovative integrated framework is providing full-text resources using MARC21 tags for the users. The librarians at any academic institution will benefit much from these instructions, stages, and methods. VuFind, which uses a single-window search technique, can also get a course reservation for library users. It is one of the advanced-level web-scale library discovery services for students and instructors to continue their educational activities during the COVID-19 pandemic using the course reserve module of Koha and VuFind

    A review of GIS-based information sharing systems

    GIS-based information sharing systems have been implemented in many of England and Wales' Crime and Disorder Reduction Partnerships (CDRPs). The information sharing role of these systems is seen as being vital to help in the review of crime, disorder and misuse of drugs; to sustain strategic objectives, to monitor interventions and initiatives; and support action plans for service delivery. This evaluation into these systems aimed to identify the lessons learned from existing systems, identify how these systems can be best used to support the business functions of CDRPs, identify common weaknesses across the systems, and produce guidelines on how these systems should be further developed. At present there are in excess of 20 major systems distributed across England and Wales. This evaluation considered a representative sample of ten systems. To date, little documented evidence has been collected by the systems that demonstrate the direct impact they are having in reducing crime and disorder, and the misuse of drugs. All point to how they are contributing to more effective partnership working, but all systems must be encouraged to record how they are contributing to improving community safety. Demonstrating this impact will help them to assure their future role in their CDRPs. By reviewing the systems wholly, several key ingredients were identified that were evident in contributing to the effectiveness of these systems. These included the need for an effective partnership business model within which the system operates, and the generation of good quality multi-agency intelligence products from the system. In helping to determine the future development of GIS-based information sharing systems, four key community safety partnership business service functions have been identified that these systems can most effectively support. These functions support the performance review requirements of CDRPs, operate a problem solving scanning and analysis role, and offer an interface with the public. By following these business service functions as a template will provide for a more effective application of these systems nationally
