    The Technical Publications staff assists DFRC authors in the preparation of research publications by advising on NASA policy concerning scientific and technical publications, recommending editorial practices and presentation of material, ensuring technical and editorial quality of manuscripts, and coordinating the typesetting and printing support. NASA research priorities are defined by the Mission Directorates (Aeronautics Research, Human Exploration & Operations, Science, and Space Technology), and NASA’s ten Centers. Each Mission Directorate and Center covers a major area of the Agency’s echnology research and t development efforts. Research Priorities for the NASA Centers.

    The Lewis Incubator helps the startup and growth of technology-based businesses with the potential to incorporate technology from the NASA Glenn Research Center. During the grant period, LIFT began operation, met or exceeded all key performance measures, and continues its operation through a new cooperative agreement with NASA Glenn and also. NASA Multi-Center Group Completes 3D LIDAR Scan for Ames Research Center and Park Researchers from NASA’s Ames Research and Armstrong Flight Research Centers conducted a physical survey of NASA Ames using a jeep roof-mounted LIght Detection And Ranging (LIDAR) system during the week.

    - Public Invited to Explore During NASA Lewis Open House The entrance gates will be wide open as well as the doors to laboratories and research facilities as NASA Lewis Research Center hosts an Open House celebrating NASA's 40th Anniversary. This free event will be held Saturday and Sunday, October 10 from 9 a.m. to 6 p.m. A study is presented on applications of computational intelligence (CI) techniques for monitoring and prognostics of machinery conditions. The machine condition is assessed through an energy-based feature, termed as “energy index,” extracted from the vibration by: 8.
