... I am developing an Informed Prefetching and Caching system as part of the kernel in which it is very important that the memory assigned to hold the data does not get swapped to disk. Without any thought to swapping I used vmalloc() to assign memory to the data structures of the Informed prefetching system. ... I later realized that most probably the pages assigned using vmalloc() were getting swapped to the disk and when I referenced them, they were brought from the disk rather than memory. ...

. The image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges in the near infrared. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: F105W (Y) blue; F125W (J) green; F160W (H) red. NASA/ESA/G. Illingworth/R.

From sembach@stsci.edu Sat Feb 16 13:56:28 2013 Date: Sat, 16 Feb 2013 13:56:27 -0500 From: Ken Sembach <sembach@stsci.edu> To: opm <opm@stsci.edu> Subject: Fwd: SADE-2R Slew Test Briefing and On-Orbit Test Results [ The following text is in the "Windows-1252" character set. ... Following verification the plan is to perform a slew under SADE-2 control to 83 degrees (a -7 degree slew) the return to 90 (a plus 7 degree slew) and verify the proper profile. ...

... The choice of which type of electricity is called "positive" and which "negative" was made around 1750 by Ben Franklin, early American scientist and man of many talents (the stamp on the left commemorates his role as first US postmaster--and colonial postmaster before that). ... Franklin knew of two types of electric charge, depending on the material one rubbed. ... Later, when electric batteries were discovered, scientists naturally assigned the direction of the flow of current to be from (+) to (-...

... BBSYN is used to set the frequency for the BBC or digital filter assigned to each baseband channel (subband channel in EVLA terminology). ... All baseband channels assigned to the same physical BBC should be assigned the same frequency. ... For the VLBA DAR and MkIV systems, the baseband frequency must be set on even 10 kHz frequencies. ... The PFB personality of the RDBE, ( DBE = RDBE_PFB ) has rather rigid baseband frequency options. ... Argument: Up to 16 frequencies in MHz. ...

... They were determined as a result of orbit improving on the base of all kinds of optical observations available in the catalog of observations of the Minor Planet Center on March 16, 2014 (radar observations have not been used at this stage). ... As the MPC orbits do not all were improved simultaneously with EMP orbits, only 383866 sets of elements were used for data comparison (for selected sets of elements process of improvement had started with the use of the same observations). ...

Describes how spatial region boundaries are handled. The golden rule for spatial region filtering was first enunciated by Leon VanSpeybroeck in 1986: . ... With this in mind, the rules for determining whether a boundary image pixel or table row are assigned to a region are defined below. For image filtering, pixels whose center is inside the boundary are included. ... That is, an row is inside the boundary without regard to its integerized pixel value. ...

Next: Flat Field Correction Up: Wavelength Calibration Previous: Identification loop . The extracted orders in the pixel domain can be resampled into wavelengths with the command REBIN/ECHELLE . Several quality checks are provided by the command IDENT/ECH . ... A method to verify the wavelength calibration consists of extracting and resampling the wavelength calibration frame and displaying the resampled image with a large scaling factor on the Y-axis. ...

... There are four independent correlator boards available in the correlator spectrometer. Each board can be assigned any available bandwidth, center frequency, sampling level, polarization, and number of channels. ... Sampling level: Your data can be sampled with either 3-level, 3-level interleaved, or 9-level sampling. 9-level operation achieves 98% of the signal-to-noise of analog correlation, whereas 3-level sampling achieves 81%. ... You cannot use 9-level sampling with a 50-MHz bandpass. ...

... ClassX is a project aimed at creating an automated system to classify X-ray sources and is envisaged as a prototype of the Virtual Observatory. ... The most fundamental are: (a) classification methods and algorithms, (b) selection and definition of classes (object types), and (c) identification of source counterparts across multi-wavelength data. ... Using different sets of training parameters (attributes), we get different classifiers for the same list of class names (e.g., Figure 1). ...
