... This means it is the end-user's responsibility to insure that the telescope does not move into a configuration that may damage it, or damage accessories attached to it. ... This driver does take these limits into account, and attempts to keep the telescope away from the pier. ... If you are using this system to control an unattended telescope, I strongly recommend that you add mechanical switches in series with the DC supply on the motor drive. ...

A descriptor , also commonly called a file handle is an object that a program uses to read or write an open file, or open network socket, or a variety of other devices. ... The operating system enforces a limit on the number of descriptors that a program can have open at a time. ... One is a kernel limitation, depending on your operating system you will either be able to tune the number of descriptors available to higher numbers (this is frequently called FD_SETSIZE ). ...

Summary of A. Skop enkov's prop osal This proposal concerns the classical Knotting Problem in topology: classify embeddings of a given space into another given space up to isotopy. ... The Knotting Problem is known to be hard. ... The Knotting Problem is most interesting for manifolds of dimension at most 4, because embeddings of such manifolds often appear in other branches of mathematics and its applications. ... For N not a homology sphere until 2005 no description of the orbits was known. ...

. Arrrrgh, it's hard to find a galaxy (even a Messier galaxy) with the full moon in the sky! . This image was taken May 11.4 UT. Nine 90 sec exposures were stacked (C14/CB245). South is up.

... We present a simple, e#ective technique that allows the con­ temporary spectroscopy of all the objects, up to a limiting magnitude, contained in a # 100 arcmin 2 field. This technique makes possible the immediate and unambiguous identification of peculiar objects included in the field. ... We show that this technique should also be quite useful in emission line and WR star surveys, and illustrate the software procedures devel­ oped to make the wavelength and flux calibration of these spectra. ...

... The data from the X-ray spectrometer RESIK, gamma spectrometer HELICON, flare spectrometer IRIS, amplitude­temporal spectrometer AVS-F, and X-ray spectrometer RPS-1 have been used to analyze the X- and gamma-ray emission from solar flares and for diagnostics of the flaring plasma. The absolute and relative content of various elements (such as potassium, argon, and sulfur) of solar plasma in flares has been determined for the first time with the X-ray spectrometer RESIK. ...

... Spectra obtained with the 6-m telescope of SAO RAS are used along with archival data from Spitzer and several ground-based telescopes to infer a strength of PAH emission, age, properties of the UV radiation field, and metallicity of studied HII complexes. Physical properties (age, radiation field parameters, metallicity) are related to the F 8 /F 24 ratio used as a proxy for the PAH abundance in order to reveal factors that may influence the PAH evolution in HII complexes. ...
