In the < tt > SubBytes </ tt > step, each byte in the state is replaced with its entry in a fixed 8-bit lookup table, S ; b < sub > ij </ sub > = S ( a < sub > ij </ sub >).

In the < tt > SubBytes </ tt > step, each byte in the state matrix is replaced with a < tt > SubByte </ tt > using an 8-bit substitution box, the Rijndael S-box.

The International Time Bureau ( BIH ) began a time scale, T < sub > m </ sub > or AM, in July 1955, using both local caesium clocks and comparisons to distant clocks using the phase of VLF radio signals.

Algeria has always been a source of inspiration for different painters who tried to immortalize the prodigious diversity of the sites it offers and the profusion of the facets that passes its population, which offers for Orientalists between the 19 < sup > th </ sup > century and the 20 < sup > th </ sup > century, a striking inspiration for a very rich artistic creation like Eugène Delacroix with his famous painting women of Algiers in their apartment or Etienne Dinet or other painters of world fame like Pablo Picasso with his painting women of Algiers, or painters issued from the Algiers school.

All 128 ASCII characters, including non-printable characters ( represented by their abbreviations ). The 95 ASCII graphic characters are numbered from 20 < sub > hexadecimal | hex </ sub > to 7E < sub > hexadecimal | hex </ sub > ( decimal 32 to 126 ).

The " space " character had to come before graphics to make sorting easier, so it became position 20 < sub > hex </ sub >; for the same reason, many special signs commonly used as separators were placed before digits.

To keep options available for lower case letters and other graphics, the special and numeric codes were arranged before the letters, and the letter " A " was placed in position 41 < sub > hex </ sub > to match the draft of the corresponding British standard.

The @ symbol was not used in continental Europe and the committee expected it would be replaced by an accented À in the French variation, so the @ was placed in position 40 < sub > hex </ sub > next to the letter A.

Because the clocks had been on average well above sea level, this meant that TAI slowed down, by about 10 < sup >− 12 </ sup >.

* If it is required to use a single number X as an estimate for the value of numbers, then the arithmetic mean does this best, in the sense of minimizing the sum of squares ( x < sub > i </ sub > − X )< sup > 2 </ sup > of the residuals.

He also offers a conversion table ( see Cohen, 1988, p. 283 ) for eta squared ( η < sup > 2 </ sup >) where 0. 0099 constitutes a small effect, 0. 0588 a medium effect and 0. 1379 a large effect.

When there are only two means to compare, the t-test and the ANOVA F-test are equivalent ; the relation between ANOVA and t is given by F = t < sup > 2 </ sup >.

With the formula C < sub > n </ sub > H < sub > 2n + 2 </ sub >, Alkanes belong to a homologous series of organic compounds in which the members differ by a constant relative molecular mass of 14.

The number of carbon atoms is used to define the size of the alkane ( e. g., C < sub > 2 </ sub >- alkane ).

The simplest possible alkane ( the parent molecule ) is methane, CH < sub > 4 </ sub >.

The species that gains the electron pair is the Lewis acid ; for example, the oxygen atom in H < sub > 3 </ sub > O < sup >+</ sup > gains a pair of electrons when one of the H — O bonds is broken and the electrons shared in the bond become localized on oxygen.

The 21st chapter was omitted from the editions published in the United States prior to 1986 .< ref > Burgess, Anthony ( 1986 ) A Clockwork Orange Resucked in < u > A Clockwork Orange </ u >, W. W.

S. audiences would never go for the final chapter, in which Alex sees the error of his ways, decides he has lost all energy for and thrill from violence and resolves to turn his life around ( a slow-ripening but classic moment of metanoia — the moment at which one's protagonist realises that everything he thought he knew was wrong ).

Under Ambrose's major influence, emperors Gratian, Valentinian II and Theodosius I carried on a persecution of Paganism .< ref name = " MacMullen1984p100 "> MacMullen ( 1984 ) p. 100: ‘ The law of June 391, issued by Theodosius [...] was issued from Milan and represented the will of its bishop, Ambrose ; for Theodosius — recently excommunicated by Ambrose, penitent, and very much under his influence < sup > 43 </ sup > — was no natural zealot.

The H — OH or H < sub > 2 </ sub > O is then released as a molecule of water, hence the term dehydration.

One is an amino group, — NH < sub > 2 </ sub >, and one is a carboxylic acid group, — COOH ( although these exist as — NH < sub > 3 </ sub >< sup >+</ sup > and — COO < sup >−</ sup > under physiologic conditions ).

The word " cipher " in former times meant " zero " and had the same origin: Middle French as < span lang =" fr "> cifre </ span > and Medieval Latin as cifra, from the Arabic صفر ṣifr = zero ( see Zero — Etymology ).

It has been estimated that about half of the Earth's mature tropical forests — between 7. 5 million and 8 million km < sup > 2 </ sup > ( 2. 9 million to 3 million sq mi ) of the original 15 million to 16 million km < sup > 2 </ sup > ( 5. 8 million to 6. 2 million sq mi ) that until 1947 covered the planet — have now been destroyed.

In 1999, objects large enough to be seen under an electron microscope — buckyball molecules ( diameter about 0. 7 nm, nearly half a million times larger than a proton ) — were found to exhibit wave-like interference .< ref > Nature: Wave – particle duality of C < sub > 60 </ sub > molecules, 14 October 1999.

Among some of the changes made in the Sherlock file format is the separation of the automatic update element ( which formed part of the < search > element ) and the icon ( provided in a separate file in Mozilla and part of the resource fork in Sherlock ).

At API level, these changes must be done between running < tt > fork </ tt > and < tt > exec </ tt >.

Unlike locks created by < tt > fcntl </ tt >, those created by < tt > flock </ tt > are preserved across < tt > fork </ tt > s, making them useful in forking servers.

It is therefore possible for more than one process to hold an exclusive lock on the same file, provided these processes share a filial relationship and the exclusive lock was initially created in a single process before being duplicated across a < tt > fork </ tt >.
