The new TCC uses one socket per device (e.g. axis controller or mirror); the old TCC allowed multiple axes to be controlled by one LAT stream. ... The new TCC also communicates with hardware controllers via TCP/IP instead of LAT; this has the potential to reduce the use of terminal servers at APO. ... Set and Show ExpTime . ...

We model the spectral chanages of late oxygen-rich Miras observed in different pulsation phases. From a combination of variable near-IR spectra and UKIRT spectrophotometry of the 9.7 \mu m silicate dust emission feature in different phases we study the influence of the changing atmospherical circumstances on the conditions in the circumstellar dust shell. ... A comparision with the modelling results for another long period Mira U Ori is also provided. ...

... This article is part of the LWN Porting Drivers to 2.6 series . This article serves as a sort of final resting place for various small changes in the kernel programming API which do not fit elsewhere. The kdev_t type has been removed from the kernel; everything which works with device numbers should now use the dev_t type. ... Consider using these while fixing your code; the next time the type of i_rdev changes, you will be happier. ... Driver porting: miscellaneous changes, designated inits . ...

Next: The stage and Up: The ESO Red Sky Previous: Artefacts . Fig. 3 shows the distribution of stars. The most striking feature is the rapid steepening of the density gradient towards the Milky Way region at the right and left hand edges of the total field, apparent from the dramatic change in colour in this false colour presentation. Noticable changes in star density across even short distances are indicated by colour changes within individual plates. ... Fig. ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . THE CHANGING UNIVERSE: EVOLUTION HAPPENS! . b) Changes in Stars . One of the great discoveries of modern science is that stars (like people) live only a measurable life-time and then die. Although the lives of the stars are enormously longer than the span of a human life, we can learn about the life story of the stars by studying them at many different stages in their life cycle, from birth to death. ...
