... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

Next: Piping in a C program Up: Running UNIX Commands from C Previous: wait() . int exit(int status) - terminates the process which calls this function and returns the exit status value. Both UNIX and C (forked) programs can read the status value. By convention, a status of 0 means normal termination any other value indicates an error or unusual occurrence. ... A complete example of forking program is in Appendix and is originally titled fork.c . ... Wed Sep 14 10:06:31 BST 1994 ...

multi-rsh is a perl script which runs the same command on multiple machines, in parallel, and provides reasonable, adjustable timeouts for those machines which fail to answer. Both standard output and standard error are returned through the same channel, and all output has the hostname prepended to each line. Multi-rsh must be run as root (remote jobs can be set to run as any user, see Options below). ... Neither form allows you to directly pass input to the remote programs. ...

... There are compelling reasons for the pulsar community to utilise a standard data storage format. For example, standardisation of file formats significantly decreases the amount of effort required to integrate new instruments into the analysis chain. ... Accordingly, we have defined PSRFITS as a standard FITS-based format for pulsar data files. ... For example, the first line of Processing History HDU contains information about the data acquisition program and the initial structure of the file. ...

... This file is intended to provide a basic functional overview of the EISA Bus, so that hobbyists and amateurs can design their own EISA compatible cards. ... EISA is upwardly compatible, which means that cards originally designed for the 8 bit IBM bus (often referred to as the XT bus) and cards designed for the 16 bit bus (referred to as the AT bus, and also as the ISA bus), will work in an EISA slot. ... This is used by the slave device to inform the bus master that it is capable of 16 bit transfers...

... The pinhole simulation program is a computationally and memory intensive task. ... A parallel version was developed instead, to enable distributed processing on a cluster of workstations. The program makes use of the Message Passing Interface (MPI) standard for parallel processing, implemented as an API (Application Programming Interface) to the Local Area Multicomputer (LAM) programming environment developed at the Ohio Supercomputer Center. ...

... While the original POS1 was doing everything in one programme, the MIDAS version has been split in 3 steps: . read the measurements and standard stars, and compute the transformation parameters (this step is performed by the ASTROM/TRANSFO, possibly called by the nicer interface of ASTROM/AUTO) . edit the standard star table to remove/restore some stars (this step is performed by ASTROM/EDIT, or with the nicer interface of ASTROM/AUTO) . ... Requires MIDAS version 97NOV or newer. ...

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). ...

The two main numerical libraries in Fortran 90 are . NAG Numerical Libraries for Fortran 90 Users . IMSL Fortran 90 MP Library Both of these offer both a modified version of the Fortran 77 library, recompiled for Fortran 90, and a completely new library, using all the new facilities of Fortran 90. ... On the Sun using Sun OS 4.2.1 we also got completely wrong results when using library functions in single precision, since the C system on Sun converted all function calls into double precision. ...

... Although many of the images are used for teacher-driven activities, students do have the opportunity to work with scientists on original research projects. ... The primary goal is to have teachers experience astronomy research and then to bring the research data into their classrooms via the internet. ... They also learn how to process their data, build a solar telescope to take home to their classrooms, and learn background information from astronomers in each of the three research areas. ...

To run a process in the background as a job and carry on working add an (ampersand) at the end of the command line. ... The shell forks a child process to run the command and displays the job number ( [ n ] ) and the PID (Process IDentifier) number. ... If the command is likely to produce error messages you will need to redirect standard error. ... Do not run an interactive command that requires you to type something at the terminal as a background job. ... You will then have to kill its process . ...

... Right: Corresponding scan tracks for the same date ( red ) and previous dates ( blue ), which cover about 2/3 of the map area (the field was completed on June 15). ... The I-GALFA survey area is divided into several fields with different declination ranges. ... By starting each subsequent night at a different position, we can cover the entire map area by ``weaving'' many such tracks together to build up a complete image of the sky brightness at all positions in the field. ...

Optical and UV Spectrophotometric Standard Stars . ... Apache Point expresses its thanks to J. R. Walsh and to ESO for allowing us to place a copy of these pages at Apache Point. ... Access to the standards is either through: . ... The data for the standard stars come from four sources: . ... Data for 23 stars based on IUE and optical spectra and calibrated by the primary WD standards. ... The data from which the plots were produced are also available by ftp access from the standard star pages. ...

The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...
