Foreword to LEO Article
As part of the reorganization of the JAIS Journal in 2002 the newly formed editorial team has decided to open the pages of the JAIS journal to the recipients of the Leo awardthe most distinguished award of AIS. The LEO Award was established in 1999 by the Council of the Association for Information Systems and the Executive Committee of the International Conference on Information Systems. Named ...
متن کاملAnalysing the Orbital Movement and Trajectory of LEO (Low Earth Orbit) Satellite Relative to Earth Rotation
Next generation of wireless Internet scenarios include LEOs (Low Earth Orbit Satellites). Lower altitudes of LEO constellations could allow global coverage while offering: low end-to-end propagation delay, low power consumption, and effective frequency usage both for the users and the satellite network. LEOs rotate asynchronously to the earth rotation. Fast movement of LEOs makes it necessary t...
متن کاملBig LEO and Now Through LEO
The advent of low earth orbit (LEO) commercial communication satellites provides an opportunity to dramatically reduce Telemetry, Tracking and Control (TT&C) costs of launch vehicles, Unpiloted Aerial Vehicles (UAVs), Research Balloons and spacecraft by reducing or eliminating ground infrastructure. Personnel from the Goddard Space Flight Center’s Wallops Flight Facility (GSFC\WFF) have success...
متن کاملAuthor's Response to Dr. Leo
Khush Mittal I read the paper by Chi et al. with interest. The authors found a greater hypoxia response gene expression in carcinomas than stromal cells grown in vitro, but were not sure of the underlying explanation (see Discussion in [1]). The underlying explanation may be the difference in mitotic activity and hence metabolic activity between these two cell types, such that hypoxia may be pr...
متن کاملSBF distances to Leo and Virgo using the HST ?
We have used archive HST WFPC2 data for three elliptical galaxies (NGC 3379 in the Leo I group, and NGC 4472 and NGC 4406 in the Virgo cluster) to determine their distances using the Surface Brightness Fluctuation (SBF) method as described by Tonry and Schneider (1988). A comparison of the HST results with the SBF distance moduli of Ciardullo et al (1993) shows significant disagreement and sugg...
