However, unlike sed , mod_sed doesn't take data from standard input. Instead, the filter acts on the entity data sent between client and server. mod_sed can be used as an input or output filter. mod_sed is a content filter, which means that it cannot be used to modify client or server http headers. ... mod_sed . ...

Optical Filters . The polarizer quads were also designed to map onto a four-faceted WFC configuration and, consequently, also require a partial filter rotation of -33 degrees to move the filter quadrant 1 (nominal polarization angle 135 degrees ) into WFCs 2 and 3, with some vignetting of both camera fields. Several additional partial rotations have been added to allow observations with different polarization angles on the same CCD. ...

... Animation . Arrow . ... I created the first animation by running Script-Fu / Animators / Fire on the head of an arrow. ... I merged the animation with the background image, and specified a final X offset of -128 (the background is 128 pixels wide). This results in an animation with a nice moving background. Note that you can also use a background that is wider than the image, as long as you specify the width of the background for the final X offset if you want the final animation to loop. ...

... Apache HTTP Server Version 2.2 . ... Filter Types . ... It is important to make the distinction between a protocol and a resource filter. ... If you are writing a filter and you want to know if it is resource or protocol, the correct question to ask is: "Can this filter be removed if the request is redirected to a different resource?" ... So, instead of starting from scratch, we simply point the front of the resource filters for the sub-request to the front of the protocol filters for the old...

Radio Interferometry Principles . Radio Interferometry Signal Processing . ... A radio interferometer consists of a pair of directional antennas that are tuned to receive radio emissions from a source in a desired RF band. ... The antennas are pointed at the radio source of interest and are set up to receive the signal and process it into a form suitable for transmission to the correlator. ... In connected element interferometry, the digital signal goes directly to the correlator. ...
