. Unix allows you to link two or more commands together using a pipe. The pipe takes the standard output from one command and uses it as the standard input to another command. command1 | command2 | command3 . The | (vertical bar) character is used to represent the pipeline connecting the commands. With practise you can use pipes to create complex commands by combining several simpler commands together.

This diagram shows how the 'vertical-align' properties on cells combine to determine the height of the row containing the cells. The diagram also illustrates the meaning of some values of 'vertical-align' that apply to table cells: baseline, top, bottom, and middle. The diagram shows a row of five (labeled) table cells of varying heights and alignments. ... The first cell is aligned with the row baseline and extends to just below the row top. ...

We have designed the laboratory model of static Fourier spectrometer for onboard usage for spectral study of atmosphere and ionosphere. The gain of model is to simulate onboard FS which will not have any moving elements (all its optical elements will be mounted at fused quartz monolithic construction), to compare experimental results with theoretical estimations and to measure MTF of CCD array. ... This fact connected with low frequency response of CCD array due to small format of it. ...
