An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . ... a) Changes in the Solar System - Continued . The Cratered Face of the Moon Impact craters on the Earth, Moon, and other worlds are formed by the bombardment of chunks of rock and ice from space. ... So we conclude that the solar system experienced many more impacts in the distant past than today. ...

Changes in the WFPC2 observation scheduling system were introduced early in 1999 primarily in order to increase the scheduling efficiency of HST observations starting with Cycle 8. First, the South Atlantic Anomaly (SAA) contours used to limit WFPC2 observations have been modified slightly. ... This change results in a 3% increase in designated SAA-free orbits, which allows better scheduling efficiency, and is expected to impact negatively less than 0.1% of WFPC2 science observations. ...

... This article is part of the LWN Porting Drivers to 2.6 series . One of the more significant changes in the 2.5 development series is the creation of the integrated device model. The device model was originally intended to make power management tasks easier through the maintenance of a representation of the host system's hardware structure. ... Which devices exist in the system, what power state they are in, what bus they are attached to, and which driver is responsible for them. ...

The input signals must be band limited to between m*fn and (m+1)*fn, where fn is the Nyquist frequency for the sampling and m is an integer 0, 1, 2 , 3 .. ... Ideally, the bandpass should be level within +/- 1 db across 90% of the band, but differences of up to 10 db are OK provided data calibration is done carefully. ...

... STScI previously used Microsoft Word and Microsoft Access, a Sybase ODBC driver, and the Adobe Acrobat PDF writer, along with a substantial amount of Visual Basic, to generate a variety of documents for the internal Space Telescope Grants Administration System (STGMS). ... To create a document, the internal STGMS application invoked a VB program which launched Microsoft Word and Microsoft Access, Access extracted the required data from a Sybase database using ODBC into an Access table. ...

A.I.Neishtadt . Probability phenomena in perturbed dynamical systems . ... If in a deterministic dynamical system a small variation of initial conditions produces a significant change of motion, then the behavior of such a system is practically non-distinguishable from a random one. ... Such quasi-random behavior exists also in systems which differ by an arbitrary small perturbation from systems with a very simple (periodic or quasi-periodic) dynamics. ...
