... INSTITUTE OF RADIOENGINEERING AND ELECTRONICS . ... The use of such a division is shown to open wide possibilities for application of chaos in modern communication systems and computer networks. Novel quality of the systems and networks can be achieved by means of not only designing new technological hardware, but also by modification of certain equipment modules and corresponding software. Examples of using chaotic encoding for computer networks are considered. ...

... It uses the transformation parameters computed by the command ASTROMET/TRANSFORM . ... ASTROMET/COMPUTE computes the RA,Dec coordinates from X,Y coordinates directly from the transformation parameters, while it obtains X,Y from the RA,Dec ones in an iterative manner. Also note that the equinox of the computed coordinates is the same as the standard star catalogue (which is NOT necessarily the same as its epoch) and is 2000.0 in case the PPM catalogue is used. ...

ON THE IMPACT OF THE GALACTIC ABERRATION ON VLBI-DERIVED PRECESSION MODEL Z.M. MALKIN Pulkovo Observatory Pulkovskoe Ch. ... Corrections to adopted precession rate are usually computed from the linear trends in long-term time series of celestial pole offset (CPO), which are the differences between the measured and the theoretical coordinates of the celestial pole. ... CONCLUSIONS We have estimated the impact of GA on parameters of precession-nutation model derived from VLBI observations. ...

SAS home . SAS Watchout items . ... OM data processing from A to Z is performed by two "chains": omichain and omfchain , for image and fast mode data respectively. ... OM fast mode data are fully processed by the XMM-SAS Pipeline: for each exposure of a given observation all necessary corrections are applied to the data files. Then a pseudo-image is built from the corrected event list and a source detection algorithm is used to find the source (or sources) present in the fast window. ...

... It is kept running by a periodic timer interrupt generated by PC hardware. If the system has too many processes running, it may take too long to service the timer interrupt, and the software clock starts slipping behind. ... If you boot your computer often (as is the case for most systems that aren't servers), it will usually keep fairly accurate time. ... By running one these commands regularly, your computer will keep as accurate time as the remote computer. ...

The aim of this section of the course is to enable you to use simple computer programs to solve a variety of common astronomical tasks. ... I have (somewhat arbitrarily) decided to use Python for this course, because it seems to be gaining popularity fast for astronomical data handling, and because some of you will have encountered it at the ATNF course. ...
