In this chapter we will consider two very simple but useful Web agents that I have written on Actor Prolog for my own needs. ... Let us start the Web agent. Fig. ... Start of the Web agent. The Context diagram consists of three blocks: "Logic Programming Sites", "Edit", and "Check". ... Some Web sites that are linked with the logic programming and Prolog are listed in the pulldown list (these addresses are transferred to the "Edit" block from the "Logic Programming Sites" block). ...

... However, while low mass stars are usually found to form in loose groups with densities of a few stars per cubic parsecs, high mass stars are known to form in dense clusters with up to 10000 stars per cubic parsec. ... We have undertaken a survey of a cospicuous number of fields around intermediate mass young stars (Herbig Ae/Be stars, HAeBe) with the aim of detect and characterize the groups of young stars that may have formed together with the HAeBe star. ...

... The technology needed to implement a Distributed Astronomical Data Archive (DADA) is available today (e.g., Fullton 1993). Query interface standards are needed, however, before the DADA information will be discoverable. ... These parameters would be used to index each dataset in each catalog. ... The technology is available today to perform cross-catalog queries, to fetch the data at the click of a mouse, quickly to add new observation catalogs, and to distribute the load across multiple machines. ...

This directory contains prototypes for scripts that may be called by the camera driver. ... The script set_camera_filter should take a filter number as an argument and send a command to a filter wheel. The SBIG filter wheel is supported internally and does not use this script. If you have another filter wheel, then a script such as this would allow you to use XmCCD to control the filter wheel. ... Simply "make" the routine in the ifw directory, and then "make install". ...

A beam of light will travel 9,500,000,000,000 kilometers in one year. This distance is defined as a light year ; the distance light travels in a year. ... This is another example of Bad Astronomy; like a light year, a parsec is a unit of distance, not time (to be specific, it equals 3.26 light years) . ...
