The radius of the event horizon of a black hole with the mass of the Sun would be about 3 kilometers, about the same size as your city, town or village. If the Earth could be compressed into a black hole, the radius of its event horizon would be 1/330,000 of this, because the mass of the Earth is 1/330,000 times the mass of the Sun. ... 30,000,000 . ... 20,000 . ...

... The ewavelet tasks detects sources using wavelet transforms. ... Figure: Solid line: The mexican hat wavelet function. Dashed line: a gaussian function with the same parameter . ... Since the image is convolved with the MH function the MH acts like a sort of sliding cell: the positive part being the source cell and the negative part being background area. From this it is clear that the wavelet scale should be smaller than the image itself in order to get a well defined image convolution. ...

... Routines for accessing I/O ports are in /usr/include/asm/io.h (or linux/include/asm-i386/io.h in the kernel source distribution). ... Before you access any ports, you must give your program permission to do so. This is done by calling the ioperm() function (declared in unistd.h , and defined in the kernel) somewhere near the start of your program (before any I/O port accesses). ... For example, ioperm(0x300, 5, 1) would give access to ports 0x300 through 0x304 (a total of 5 ports). ...
