    Get PDF
    The Spaceport Processing Systems Branch at NASA Kennedy Space Center has developed and deployed a software agent to monitor the Space Shuttle's ground processing telemetry stream. The application, the Launch Commit Criteria Monitoring Agent, increases situational awareness for system and hardware engineers during Shuttle launch countdown. The agent provides autonomous monitoring of the telemetry stream, automatically alerts system engineers when predefined criteria have been met, identifies limit warnings and violations of launch commit criteria, aids Shuttle engineers through troubleshooting procedures, and provides additional insight to verify appropriate troubleshooting of problems by contractors. The agent has successfully detected launch commit criteria warnings and violations on a simulated playback data stream. Efficiency and safety are improved through increased automation

    Monitoring Agents for Assisting NASA Engineers with Shuttle Ground Processing

    The Spaceport Processing Systems Branch at NASA Kennedy Space Center has designed, developed, and deployed a rule-based agent to monitor the Space Shuttle's ground processing telemetry stream. The NASA Engineering Shuttle Telemetry Agent increases situational awareness for system and hardware engineers during ground processing of the Shuttle's subsystems. The agent provides autonomous monitoring of the telemetry stream and automatically alerts system engineers when user defined conditions are satisfied. Efficiency and safety are improved through increased automation. Sandia National Labs' Java Expert System Shell is employed as the agent's rule engine. The shell's predicate logic lends itself well to capturing the heuristics and specifying the engineering rules within this domain. The declarative paradigm of the rule-based agent yields a highly modular and scalable design spanning multiple subsystems of the Shuttle. Several hundred monitoring rules have been written thus far with corresponding notifications sent to Shuttle engineers. This chapter discusses the rule-based telemetry agent used for Space Shuttle ground processing. We present the problem domain along with design and development considerations such as information modeling, knowledge capture, and the deployment of the product. We also present ongoing work with other condition monitoring agents

    The Bumpy Road from Paris to Brussels: The European Commission Governance Incentive Tranche

    Get PDF
    The EC recently launched a new aid instrument for the ACP-community: the “governance incentive tranche”, a modality designed to incentivise ACP-governments to carry out governance reforms. In this paper we analyse whether this new initiative incorporates the principles spurred by the aid effectiveness debate and adopted by the Paris declaration (2005). Evidence suggests that in design and practice, the incentive tranche is surprisingly similar to some of the unsuccessful aid modalities of the past. The paper argues that in order to fully grasp the complexity of donor behaviour, the donor’s domestic issues and political arrangements have to be brought into the analysis. The incentive tranche illustrates how the complexity of the European construction makes formulation of a coherent policy exceptionally difficult.

    Shaping Global Partnerships for a Post-2015 World

    As we discuss the post-2015 development agenda, how can we empower global partnerships to achieve the transformational change we need for a better future? This article provides lessons and best practices from six diverse initiatives on applying the collective impact approach on a global scale -- how to develop a common agenda, operate effective shared measurement systems, support and coordinate activities, facilitate communication, and provide strong governance for global collaborative efforts.The report uses a collective impact lens to research and evaluate a range of global partnerships, with a particular emphasis on these six diverse initiatives: Roll Back Malaria Partnership, Global Alliance for Improved Nutrition, Global Road Safety Partnership, the World Economic Forum's New Vision for Agriculture, the Global Partnership for Education, and the World Wide Fund for Nature

    An analysis of Space Shuttle countdown activities: Preliminaries to a computational model of the NASA Test Director

    Get PDF
    Before all systems are go just prior to the launch of a space shuttle, thousands of operations and tests have been performed to ensure that all shuttle and support subsystems are operational and ready for launch. These steps, which range from activating the orbiter's flight computers to removing the launch pad from the itinerary of the NASA tour buses, are carried out by launch team members at various locations and with highly specialized fields of expertise. The liability for coordinating these diverse activities rests with the NASA Test Director (NTD) at NASA-Kennedy. The behavior is being studied of the NTD with the goal of building a detailed computational model of that behavior; the results of that analysis to date are given. The NTD's performance is described in detail, as a team member who must coordinate a complex task through efficient audio communication, as well as an individual taking notes and consulting manuals. A model of the routine cognitive skill used by the NTD to follow the launch countdown procedure manual was implemented using the Soar cognitive architecture. Several examples are given of how such a model could aid in evaluating proposed computer support systems

    Communities of Change, Multi Stakeholder Processes, Lobby & Advocacy : More than 100 years of experience on HBC in Malawi & Zambia!

    Get PDF
    This training of four days focussed on two areas of capacity development of the home-based care (HBC) alliance in Malawi and Zambia: 1. Communities of Change (CoC) concept and practice linked to the Multi Stakeholder Process (MSP), and 2. Lobby & Advocacy (L&A). Since June 2010 Cordaid started together with the Centre of Development Innovation (CDI) a learning and development process on the Communities of Change concept and practice linked to the Multi Stakeholder Process with around 75 persons of her staff. In order to share and deepen the development of the COC & MSP concepts and practice further with the partners in the field, Cordaid organised this training. An effective working Alliance/CoC is a condition for effective lobby and advocacy. Therefore the CoC - MSP part of the training was directly linked to the part on lobby and advocacy. The lobby and advocacy trajectory had been started already three years ago with an initial training (also in Malawi) specifically on lobby and advocacy for home based care representatives of eight countries in Africa, amongst other Malawi and Zambia. The current training on lobby and advocacy is therefore also part of the follow up of that process

    Deepening Democracy in Buffalo by Honoring Prior Commitments (And a Legacy)

    Get PDF
    The waning years of the 2010s and the opening weeks of the 2020s have been rife with headlines, editorials, academic articles, lectures, and book titles lamenting a “crisis of democracy”. Among other things, the concerned authors and observers participating in the discourse cite foreign election interference; the global rise of populist authoritarians; the exorbitant financial costs of electoral politics and the attendant subordination of policy to wealth and corporate interests; increasing social and cultural cleavages and polarization; sharply rising inequality; the ongoing erosion of public trust; and a host of other factors as both causes and consequences of the present weakened state of democracy in and beyond the United States. Not surprisingly, in light of these trends, strengthening democratic institutions and expanding democratic participation are among the highest priorities included in proposals to combat intersecting social, economic, and ecological problems from local gentrification to global climate change. With that in mind, this policy memo highlights two opportunities for the City of Buffalo, New York to answer these urgent calls to deepen democracy. Both opportunities—promoting worker cooperatives and the use of participatory budgeting—have already been experimented with in Buffalo, and have received meaningful resource commitments from the City in the recent past. Earlier progress on those fronts is part of the legacy of former Delaware District Council Member Michael J. LoCurto, who championed both causes through legislation and advocacy. Honoring that legacy means renewing prior commitments to these causes and ensuring that they become lasting fixtures of local governance

    Mission safety evaluation report for STS-37, postflight edition

    Get PDF
    STS-37/Atlantis was launched on April 5, 1991 from Kennedy Space Center launch complex 39B at 9:23 a.m. Eastern Standard Time (EST). Launch was delayed 4 minutes 45 seconds because of safety concerns about the low cloud ceiling and the wind direction in the potential blast area. Based on the limited number and type of inflight anomalies encountered, the Space Shuttle operated satisfactorily throughout the STS-37 mission. A contingency EVA was performed by the crew on Flight Day (FD) 3 to free a sticky Gamma Ray Observatory (GRO) high gain antenna, after which the GRO primary payload was successfully deployed by the Orbiter's Remote Manipulator System. The GRO, which weighed just over 35,000 lbs, was the heaviest NASA science satellite ever deployed by the Space Shuttle into low Earth orbit. The scheduled entry/landing on FD 6 was waved off for one day due to high wind conditions at Edwards Air Force Base. Atlantis landed on FD 7, 11 April 1991 on Edwards AFB lakebed runway 33 at 9:55 a.m. Eastern Daylight Time
