... We describe a parallel code for 3-D structure detection and morphological analysis. The method is based on a multiscale technique, the wavelet transform and on segmentation analysis. ... This paper presents a new parallel code, that allows a rapid structure detection and morphological analysis in a 3-D set of data points. ... Segmentation analysis. ... Our code is based on the programming paradigm MASTER/SLAVE . ... Finally, the morphological analysis is executed by the master. ...

... Omdetect uses two different algorithms for source-detection - one is optimised for detecting point-like sources, and the second is optimised for detecting extended sources. ... Two separate lists are used mainly because the detection algorithms for point and extended sources are different, and also because the photometry of the two types is done differently. ... The number of pixels that an extended source contains. ... Point-source detection algorithm . ... Extended-source detection Algorithm . ...

... 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. ...

Astronomical Data Analysis Software and Systems VII ASP Conference Series, Vol. ... A Wavelet Parallel Code for Structure Detection A. Pagliaro Istituto di Astronomia dell'Universit‘a di Catania U. Becciani, V.Antonuccio and M.Gambera Osservatorio Astrofisico di Catania Abstract. We describe a parallel code for 3­D structure detection and morphological analysis.

... 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 (-...

. 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.
