... 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 (-...

... 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. ...

Next: PyFITS, a FITS Module for Python . ... Pirzkal, N. & Hook, R. N. 1999, in ASP Conf. ... Python is a powerful, object-oriented scripting language that is easy to extend, free, and available for most computer platforms. Python, together with its Numerical module, and with the pFitsio module that is being developed by one of the authors, provides an attractive alternative to other languages such as Perl, IDL, and the IRAF CL, which are already widely used by the community. ...

Next: A Preliminary Investigation Up: Spatial Corrections of ROSAT Previous: Introduction . ... These tasks bin a time sorted photon event list based on an assigned phase that corresponds to the 402 second period of the wobble. ... The fundamental limitation of this method is how many source counts you have for centroiding each binned image section. ... Once the phase binned qpoes have been shifted in x,y so as to align the source centroid, they are restacked using 'qpappend_ftsi'. ...

... Although many of the images are used for teacher-driven activities, students do have the opportunity to work with scientists on original research projects. ... The primary goal is to have teachers experience astronomy research and then to bring the research data into their classrooms via the internet. ... They also learn how to process their data, build a solar telescope to take home to their classrooms, and learn background information from astronomers in each of the three research areas. ...
