    Based on the UK open access life cycle, in the centre circle, we have used the 7 stages of the publishing process as described by Neil Jacobs (Jisc), this is followed by institutional processes – of course not all institutions will have all of these processes up and running, e.g. we don’t all have a CRIS. We then included publisher services that directly impact upon the work of the open access team. We then went on to map above campus services to the life cycle. Finally, we added the 6 sections of OAWAL showing where we think that fits with the life cycle

    Open Access/Open Research/Open Government: The Full Cycle of Access to Government Information

    Stephanie Braunstein, Head Government Documents Librarian at Louisiana State University, and Maggie Kauffman, Senior Librarian and Housing Resource Coordinator at the California Department of Housing and Community Development, will describe the who, what, why, and how of current initiatives that promote the sharing of government-funded research--at both the federal and state levels. Emphasis will be placed on recent legislative efforts (such as the Fair Access to Science and Technology Research Act [FASTR]) and on the recommendations of various professional library organizations that support academic research (such as the Association of Research Libraries [ARL]). While much of the current discussion surrounding this issue takes place at the federal level, open access to information at the state level is vital in order to insure an educated and informed local population. After the informational portion of the presentation, the presenters will open up the floor for discussion with the intention of sharing a variety of perspectives on the government\u27s funding of research and how best to provide fair and equitable access to it

    Assessment of disk MHD generators for a base load powerplant

    Results from a study of the disk MHD generator are presented. Both open and closed cycle disk systems were investigated. Costing of the open cycle disk components (nozzle, channel, diffuser, radiant boiler, magnet and power management) was done. However, no detailed costing was done for the closed cycle systems. Preliminary plant design for the open cycle systems was also completed. Based on the system study results, an economic assessment of the open cycle systems is presented. Costs of the open cycle disk conponents are less than comparable linear generator components. Also, costs of electricity for the open cycle disk systems are competitive with comparable linear systems. Advantages of the disk design simplicity are considered. Improvements in the channel availability or a reduction in the channel lifetime requirement are possible as a result of the disk design

    Energy Conversion Alternatives Study (ECAS), General Electric Phase 1. Volume 2: Advanced energy conversion systems. Part 1: Open-cycle gas turbines

    Get PDF
    Ten energy conversion systems are defined and analyzed in terms of efficiency. These include: open-cycle gas turbine recuperative; open-cycle gas turbine; closed-cycle gas turbine; supercritical CO2 cycle; advanced steam cycle; liquid metal topping cycle; open-cycle MHD; closed-cycle inert gas MHD; closed-cycle liquid metal MHD; and fuel cells. Results are presented

    Role of coronal mass ejections in the heliospheric Hale cycle

    [1] The 11-year solar cycle variation in the heliospheric magnetic field strength can be explained by the temporary buildup of closed flux released by coronal mass ejections (CMEs). If this explanation is correct, and the total open magnetic flux is conserved, then the interplanetary-CME closed flux must eventually open via reconnection with open flux close to the Sun. In this case each CME will move the reconnected open flux by at least the CME footpoint separation distance. Since the polarity of CME footpoints tends to follow a pattern similar to the Hale cycle of sunspot polarity, repeated CME eruption and subsequent reconnection will naturally result in latitudinal transport of open solar flux. We demonstrate how this process can reverse the coronal and heliospheric fields, and we calculate that the amount of flux involved is sufficient to accomplish the reversal within the 11 years of the solar cycle

    In the centre circle, we have used the 7 stages of the publishing process as described by Neil Jacobs (Jisc), this is followed by institutional processes – of course not all institutions will have all of these processes up and running, e.g. we don’t all have a CRIS. We then included publisher services that directly impact upon the work of the open access team and also Jisc OA services. We then went on to map Jisc OA and above campus services to the life cycle – doing this we immediately found an issue with Publication Router, which is why we have included it twice, once where it currently affects the life cycle and once where we think it should sit – at point of acceptance. Finally, we added the 6 sections of OAWAL showing where we think that fits with the life cycle

    Energy Conversion Alternatives Study (ECAS), Westinghouse phase 1. Volume 4: Open recuperated and bottomed gas turbine cycles

    Get PDF
    Open-cycle recuperated gas turbine plant with inlet temperatures of 1255 to 1644 K (1800 to 2500 F) and recuperators with effectiveness values of 0, 70, 80 and 90% are considered. A 1644 K (2500 F) gas turbine would have a 33.5% plant efficiency in a simple cycle, 37.6% in a recuperated cycle and 47.6% when combined with a sulfur dioxide bottomer. The distillate burning recuperated plant was calculated to produce electricity at a cost of 8.19 mills/MJ (29.5 mills/kWh). Due to their low capital cost 170to200170 to 200 /kW, the open cycle gas turbine plant should see duty for peaking and intermediate load duty
