... Most of the interesting R being done is in the B-ISDN world, and in the world of applications. ... The set of interoperability standards referred to is called National ISDN . The standardizing of applications is really separate from the ISDN standards themselves, but these applications will be important to the future success of ISDN.

... The algorithm has been successfully applied to both real and simulated astronomical data (Jefferies , 1993; Jefferies 1993) and its ability to accurately preserve photometry in the observed image has been demonstrated. ... In order to investigate the algorithm's performance without the influence of detector and photon noise we took the ``truth'' data set and convolved it with the given PSF to generate a noiseless image. ... The restored object and the two restored PSF's are shown in Fig. ...

... First of all, I should say that you cannot guarantee user-mode processes to have exact control of timing because of the multi-tasking nature of Linux. ... However, for most applications using I/O ports, this does not really matter. To minimise this, you may want to nice your process to a high-priority value (see the nice(2) manual page) or use real-time scheduling (see below). ... Linux 2.x kernels have soft real time support; see the manual page for sched_setscheduler(2) for details. ...

... Previous: A Posteriori Guidance for Astronomical Images . ... We present an original algorithm for the recognition of anomalous events in a CCD frame (i.e., cosmic hits, bad pixels etc.) The algorithm is able to distinguish between these events and real features by comparing the standard deviation and the kurtosis of a synthetic PSF, whose width is given by the user, and the corresponding values in a running window, whose size is chosen by the user, in the actual frame. ...
