Thirdly, CRC is a linear function with a property that CRC ( X XOR Y ) = CRC ( X ) XOR CRC ( Y ); as a result, even if the CRC is encrypted with a stream cipher ( or mode of block cipher which effectively turns it into stream cipher, such as OFB or CFB ), both message and associated CRC can be manipulated without knowledge of encryption key ; this was one of the well-known design flaws of the Wired Equivalent Privacy ( WEP ) protocol.

where Y is a matrix with series of multivariate measurements, X is a matrix that might be a design matrix, B is a matrix containing parameters that are usually to be estimated and U is a matrix containing errors or noise.

In multivariate tests the columns of Y are tested together, whereas in univariate tests the columns of Y are tested independently, i. e., as multiple univariate tests with the same design matrix.

There was only one way to accomplish this: by design, by drawing diagrams and sketches in which he probed the remotest corner of his mind for creative ideas to carry his concept.

Bicycle gear-sets he had once used as the basis of the design for the Camden Cycly Company plant hung on a rope in one corner, and over his desk, next to several old and dusty hats, was a clean pair of roller skates which he occasionally used up and down in front of his house.

Like many others, he had to work hard, long hours in a struggling family business which, though it was allied to art of a kind -- the design and production of engraved seals -- bore no relation to the painting of pictures.

With greater investments in plant facilities, with automation growing, you can't switch around, either in volume or in product design, as much as was formerly possible -- or at least not as economically.

); its design was planned by the government of the day ; and it places individual letters in syllable clusters with equal dimensions, in the same way as Chinese characters, to allow for mixed-script writing ( one syllable always takes up one type-space no matter how many letters get stacked into building that one sound-block ).
