    Amazon Web Services (AWS) Cloud Platform for Satellite Data Processing

    As part of NOAA’s Environmental Satellite Processing and Distribution System (ESPDS) program, Solers created a cloud platform for satellite data management and processing. It consists of Enterprise Data Management (EDM) and Enterprise Product Generation (EPG) services, hosted in an Amazon Web Services (AWS) cloud environment, leveraging AWS cloud services and existing NOAA product generation algorithms. While this cloud platform was developed in the context of NOAA/NESDIS satellite data management and processing requirements, it also has tremendous applicability and cost effectiveness for small satellite data management and processing needs. An attractive method for ingesting data from small satellites is the AWS Ground Station. This can help small satellite operators save on costs of real estate, hardware/software, and labor to deploy and operate their own ground stations. The data is ingested via AWS-managed antennas, and made available for further processing in the AWS cloud using COTS RF/ baseband over IP transport services. Once this data has been ingested and made available, the flexible REST APIs from the EDM and EPG services in the AWS cloud make it easy and cost-effective for small satellite operators to catalog and process the data into consumable products, and make them available for access to end users

    Net worth and housing equity in retirement

    Get PDF
    This paper documents the trends in the life-cycle profiles of net worth and housing equity between 1983 and 2004. The net worth of older households significantly increased during the housing boom of recent years. However, net worth grew by more than housing equity, in part because other assets also appreciated at the same time. Moreover, the younger elderly offset rising house prices by increasing their housing debt, and used some of the proceeds to invest in other assets. We also consider how much of their housing equity older households can actually tap, using reverse mortgages. This fraction is lower at younger ages, such that young retirees can consume less than half of their housing equity. These results imply that ‘consumable’ net worth is smaller than standard calculations of net worth. JEL Classification: G11, E2

    Interjurisdictional competition and the efficiency of the public sector: The triumph of the market over the state?

    Get PDF
    It has been argued in the literature that, interjurisdictional competition forces the public sector to increase its efficiency and thus helps to tame Leviathan governments. The paper addresses this hypothesis by means of a simple taxcompetition model with a Leviathan state. It is seen that the effects of increased factor mobility on the efficiency of the public sector are ambiguous. A calibration of the model shows that a reduction in public-sector efficiency is possible for parameter constellations which are not unrealistic.

    Visualizations for an Explainable Planning Agent

    In this paper, we report on the visualization capabilities of an Explainable AI Planning (XAIP) agent that can support human in the loop decision making. Imposing transparency and explainability requirements on such agents is especially important in order to establish trust and common ground with the end-to-end automated planning system. Visualizing the agent's internal decision-making processes is a crucial step towards achieving this. This may include externalizing the "brain" of the agent -- starting from its sensory inputs, to progressively higher order decisions made by it in order to drive its planning components. We also show how the planner can bootstrap on the latest techniques in explainable planning to cast plan visualization as a plan explanation problem, and thus provide concise model-based visualization of its plans. We demonstrate these functionalities in the context of the automated planning components of a smart assistant in an instrumented meeting space.Comment: PREVIOUSLY Mr. Jones -- Towards a Proactive Smart Room Orchestrator (appeared in AAAI 2017 Fall Symposium on Human-Agent Groups
