    Mapping the UK research & innovation landscape: Energy & development

    Get PDF
    The UK is already a major player in terms of research and innovation into low carbon transitions within the countries of the developing world. However, there are significant opportunities for the UK to enhance its presence within these markets whilst also making a major contribution to meeting international development targets and climate commitments. At the core of the research analysed in the report is that it reflects disparate, research initiatives funded with different research/innovation targets in mind; much latent strength in UK research for low carbon energy for development therefore is implicit in linkage possibilities enhancing systemic effectiveness, particularly by cross-fertilizing innovations taking place in the private sector. Gaps and weaknesses are reflected as much in the lack of collaborative initiatives and ‘siloization’ as in the absence of actual research/funding. The Low Carbon Energy for Development Network (LCEDN) is currently taking the initiative in one aspect of this through the provision of a programme of capacity building and partnership activities to support the development of DfID’s Transforming Energy Access research initiative. What is required of UK energy for development research for the purposes of building a functional system, however, is that the discrete areas of research outlined in this report be re-assembled as coherent, overall research narratives addressing the apparent contradiction of increasing energy access whilst transitioning to the low-carbon economy. Part of this work involves identifying the state and dynamics of UK research capacity in this sector, facilitating greater integration between research funders active in this area, evaluating gaps and key research needs and mapping potential future directions for research interventions and collaborations that build on, and develop, existing UK research capacity. It is expected that this will lead to a range of UK-led energy innovations developed, tested and scaled across developing countries by 2020. The much-needed harmonization of energy access and low carbon transition as a UK research theme however has ultimately to be created out of rethinking research fields from a combination of existing research, plus demand known to be ‘out there’ but which has yet to enter the field of vision of research-funders. This report presents the first part of this work with an overview of current UK research and innovation capacity in a widely defined ‘Energy and International Development’ research area. It identifies key institutions and research centres, thematic areas of excellence, research funding trends over the last decade, emerging research themes plus an overview of grant funding for innovation on the ground. A number of key areas/questions for potential further development of UK research and innovation capacity have been identified and are up for discussion and consultation. The work has been undertaken by LCEDN in partnership with the Knowledge Transfer Network, Energy 4 Impact and IOD PARC

    CUSTARD (Cranfield University Space Technology Advanced Research Demonstrator) - A Micro-System Technology Demonstrator Nanosatellite. Summary of the Group Design Project MSc in Astronautics and Space Engineering. 1999-2000, Cranfield University

    Get PDF
    CUSTARD (Cranfield University Space Technology And Research Demonstrator) was the group design project for students of the MSc in Astronautics and Space Engineering for the Academic Year 1999/2000 at Cranfield University. The project involved the initial design of a nanosatellite to be used as a technology demonstrator for microsystem technology (MST) in space. The students worked together as one group (organised into several subgroups, e.g. system, mechanical), with each student responsible for a set of work packages. The nanosatellite designed had a mass of 4 kg, lifetime of 3 months in low Earth orbit, coarse 3-axis attitude control (no orbit control), and was capable of carrying up to 1 kg of payload. The electrical power available was 18 W (peak). Assuming a single X-band ground station at RAL (UK), a data rate of up to 1 M bit s-1 for about 3000 s per day is possible. The payloads proposed are a microgravity laboratory and a formation flying experiment. The report summarises the results of the project and includes executive summaries from all team members. Further information and summaries of the full reports are available from the College of Aeronautics, Cranfield University

    A Proposal for the Development of a Program of the Use of Microcomputers in the Red Hill School District

    Get PDF
    In this study the current uses of microcomputers in the classroom were explored through a review of the literature and personal interviews with educators, businessmen, and computer specialists. The current innovations are examined in an effort to anticipate the technical world that students will face in the future. One must anticipate what the future needs will be to develop a program that will help the students to become contributing members of society. This study was specifically conducted to make recommendations for the uses of microcomputers in the Red Hill school district. The report focuses on the different areas of the instructional uses of microcomputers in the classroom. These different areas are: the selection and evaluation of hardware; the selection and evaluation of software; microcomputers and minicomputers; time-sharing and main frame computers; computer literacy; computer programming; drill and practice; tutorial; creative programming; computer-managed instruction; computer-assisted instruction; projected uses in the classroom by subject material; simulations and decision making; games and graphics in the classroom; introduction into the curriculum; telecommunications and their use in education; peripherals that are desirable and necessary; the choice of a supplier; computer equity and students; microcomputer politics and solutions; computer phobia and its solutions; social implications of the microcomputer; are computers cost effective; the hidden costs of microcomputers; the administrator\u27s role in adopting the microcomputer into the curriculum; microcomputers and copyright laws; microcomputers in a rural district; the funding available for microcomputer programs; why computers are not reaching their full potential; new innovations and the future; the resources available at Red Hill; and preventative maintenance and care. From the discussion of these areas, a list of specific recommendations for the instructional use of microcomputers at Red Hill is formed. Following these recommendations, a tentative timetable of adoption is presented

Measuring workers' exposure can facilitate the assessment of the effectiveness of protective and mitigation measures in place. This scoping review aims to give an overview of available methods and those already implemented for airborne virus exposure assessment in different occupational and indoor environments. The results retrieved from the various studies may contribute to the setting of future standards and guidelines to ensure a reliable risk characterization in the occupational environments crucial for the implementation of effective control measures. The search aimed at selecting studies between January 1st, 2010, and June 30th, 2023 in the selected databases. Fifty papers on virus exposure assessment fitted the eligibility criteria and were selected for data extraction. Overall, this study identified gaps in knowledge regarding virus assessment and pinpointed the need for further research. Several discrepancies were found (transport temperatures, elution steps, …), as well as a lack of publication of important data related to the exposure conditions (contextual information). With the available information, it is impossible to compare results between studies employing different methods, and even if the same methods are used, different conclusions/ recommendations based on expert judgment have been reported due to the lack of consensus in the contextual information retrieved and/or data interpretation. Future research on the field targeting sampling methods and in the laboratory regarding the assays to employ should be developed bearing in mind the different goals of the assessment.info:eu-repo/semantics/publishedVersio
