... The DAL supports Null Values (both integer and real). For objects (i.e. arrays or columns) containing integer data, it is possible to define a null value. A data value is then is considered null if it is equal to the object's null value. Integer data containing null values may be operated on safely i.e. arithmetic operations. ... Real data containing null values must be treated carefully i.e. testing for nullity before carrying out any further operations. ...

The ion rocket is another means of providing thrust, more gradually but also more efficiently than a conventional rocket. ... As in the nuclear rocket, the energy which propels the xenon jet comes from a different source; here it is electrical energy from solar cells. The reason an ion rocket is much more efficient than ordinary rockets is the way its jet is produced. ... As with solar sails, solar ion engines are mainly practical in the inner solar system, where ample sunlight is available. ...

Proceedings of the 6th IEEE International Specialist Workshop on Nonlinear Dynamics of Electronic Systems, Budapest, Hungary, 16-18 July, 1998 , pp. ... The method for synchronization of drive-response systems on conditions of a large mismatch of parameters is considered on example of the system based on modified Chua's circuit. The approach to information transmission using such method is proposed. ...

The Australia Telescope Online Archive (ATOA) is an online data store that contains the raw (uncalibrated) data files from Compact Array observations taken since 1990. ... To facilitate and encourage greater use of the archive files, the ATNF and the ICT Centre in Canberra have developed a new system that will replace the manual handling of archive data and allow users to directly access the data files via an easy-to-use web interface. ... We plan to release the ATOA in November 2004. ...

Matches any single character . ... When more than one RewriteCond is specified, they must all match for the RewriteRule to be applied. ... The main difference with per-server rewrites is that the path prefix of the directory containing the .htaccess file is stripped before matching in the RewriteRule . ...

Meteors are more than just pretty lights in the sky. Since the majority of meteor-producing meteoroids originate from comets, they contain invaluable information about these objects not otherwise obtainable. ... One such possibility is the planet Mars. ... Taking into account the slower average speed of incoming material at the heliocentric distance of Mars from the Sun, a meteoroid of the same mass entering the martian atmosphere at 30km/sec would produce a meteor +0.5 mag fainter than at Earth. ...
