    Flow Analysis Tool Whitepaper

    Faster networks are continually being built to accommodate larger data transfers. While it is intuitive to think that implementing faster networks will result in higher throughput rates, this is often not the case. There are many elements involved in data transfer, many of which are beyond the scope of the...

    Fault Tolerance in ZigBee Wireless Sensor Networks

    Wireless Sensor Networks (WSN) based on the IEEE 802.15.4 Personal Area Network standard are finding increasing use in the home automation and emerging smart energy markets. The network and application layers, based on the ZigBee 2007 PRO Standard, provide a convenient framework for component-based software that supports customer solutions from...

    Case Study for Running HPC Applications in Public Clouds

    Cloud computing is emerging as an alternative computing platform to bridge the gap between scientists' growing computational demands and their computing capabilities. A scientist who wants to run HPC applications can obtain massive computing resources 'in the cloud' quickly (in minutes), as opposed to days or weeks it normally takes...

    NASA Nebula Cloud Computing Platform

    Nebula is an open-source cloud computing platform that was developed to provide an easily quantifiable and improved alternative to building additional expensive data centers and to provide an easier way for NASA scientists and researchers to share large, complex data sets with external partners and the public. Nebula is currently...

    An Operational Local Data Integration System (LDIS) at WFO Melbourne

    A Local Data Integration System (LDIS) has been implemented at the National Weather Service (NWS) office in Melbourne, Florida (Case and Manobianco 2001). The LDIS was configured with the assistance of the NASA Applied Meteorology Unit (AMU, Ernst and Merceret 1995). This effort was undertaken to integrate the various data...

    Assessment of the 802.11g Wireless Protocol for Lunar Surface Communications

    Future lunar surface missions supporting the NASA Vision for Space Exploration will rely on wireless networks to transmit voice and data. The ad hoc network architecture is of particular interest since it does not require a complex infrastructure. This paper looks at data performance over an ad hoc network with...

    Coordinating Government Funding of File System and I/O Research Through the High End Computing University Research Activity

    In 2003, the High End Computing Revitalization Task Force designated file systems and I/O as an area in need of national focus. The purpose of the High End Computing Interagency Working Group (HECIWG) is to coordinate government spending on File Systems and I/O (FSIO) R&D by all the government agencies...

    Human Systems Integration (HSI) Case Studies From the NASA Constellation Program

    The National Aeronautics and Space Administration (NASA) Constellation Program is responsible for planning and implementing those programs necessary to send human explorers back to the moon, onward to Mars and other destinations in the solar systems, and to support missions to the International Space Station. The Constellation Program has the...

    Living Color Frame System: PC Graphics Tool for Data Visualization

    Living Color Frame System (LCFS) is a personal computer software tool for generating real-time graphics applications. It is highly applicable for a wide range of data visualization in virtual environment applications. Engineers often use computer graphics to enhance the interpretation of data under observation. These graphics become more complicated when...

    Rethinking Crew Error: Overview of a Panel Session

    This paper discusses that to improve aviation safety one must stop thinking of pilot errors as the prime cause of accidents, but rather think of errors as the consequence of many factors that combine to create the conditions for accidents. It is easy in hindsight to identify ways any given...
