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.

In practical terms, the ampere is a measure of the amount of electric charge passing a point in an electric circuit per unit time with 6. 241 × 10 < sup > 18 </ sup > electrons, or one coulomb per second constituting one ampere.

Antimony is stable in air at room temperature, but reacts with oxygen if heated to form antimony trioxide, Sb < sub > 2 </ sub > O < sub > 3 </ sub >.

Antimony exists as two stable isotopes, < sup > 121 </ sup > Sb with a natural abundance of 57. 36 % and < sup > 123 </ sup > Sb with a natural abundance of 42. 64 %.

Several unusual applications, such as a nuclear battery or fuel for space ships with nuclear propulsion, have been proposed for the isotope < sup > 242m </ sup > Am, but they are as yet hindered by the scarcity and high price of this nuclear isomer.

These states are labeled by a set of quantum numbers summarized in the term symbol and usually associated with particular electron configurations, i. e., by occupation schemes of atomic orbitals ( e. g., 1s < sup > 2 </ sup > 2s < sup > 2 </ sup > 2p < sup > 6 </ sup > for the ground state of neon -- term symbol: < sup > 1 </ sup > S < sub > 0 </ sub >).

In German, words starting with sch-( constituting the German phoneme ) would be intercalated between words with initial sca-and sci-( all incidentally loanwords ) instead of this graphic cluster appearing after the letter s, as though it were a single letter — a lexicographical policy which would be de rigueur in a dictionary of Albanian, i. e. dh -, ë -, gj -, ll -, rr -, th -, xh-and zh-( all representing phonemes and considered separate single letters ) would follow the letters d, e, g, l, n, r, t, x and z respectively.

: Precise instructions ( in language understood by " the computer ") for a fast, efficient, " good " process that specifies the " moves " of " the computer " ( machine or human, equipped with the necessary internally contained information and capabilities ) to find, decode, and then process arbitrary input integers / symbols m and n, symbols + and =

The algorithm can be extended to handle unequal sample weights, replacing the simple counter n with the sum of weights seen so far.

Each orbital is defined by a different set of quantum numbers ( n, l, and m ), and contains a maximum of two electrons each with their own spin quantum number.

In modern quantum mechanics however, n determines the mean distance of the electron from the nucleus ; all electrons with the same value of n lie at the same average distance.

For this reason, orbitals with the same value of n are said to comprise a " shell ".

Orbitals with the same value of n and also the same value of l are even more closely related, and are said to comprise a " subshell ".

Each atom has, in general, many orbitals associated with each value of n ; these orbitals together are sometimes called electron shells.

If denotes the quantum state of a particle ( n ) with momentum p, spin J whose component in the z-direction is σ, then one has

N-ary associativity is a string of length n +( n-1 ) with any n adjacent elements bracketed.

The program tries every string, starting with the shortest, until it finds a string with complexity at least n ( if there is one ), then returns that string ( or goes into an infinite loop if there is no such string ).

Clearly there is always at least one such string for any n, as otherwise all possible strings ( infinitely many ) could be generated by the ( finitely many ) programs with lower complexity, so GenerateComplexString must always return.

Therefore, given any positive integer n, it produces a string with Kolmogorov complexity at least as great as n. The program itself has a fixed length U. The input to the program GenerateComplexString is an integer n. Here, the size of n is measured by the number of bits required to represent n, which is log < sub > 2 </ sub >( n ).

AVL trees are often compared with red-black trees because they support the same set of operations and because red-black trees also take O ( log n ) time for the basic operations.

Another advantage of the use of virtual circuits comes with the ability to use them as a multiplexing layer, allowing different services ( such as voice, Frame Relay, n * 64 channels, IP ).

A slightly larger count ( but still better than split radix for N ≥ 256 ) was shown to be provably optimal for N ≤ 512 under additional restrictions on the possible algorithms ( split-radix-like flowgraphs with unit-modulus multiplicative factors ), by reduction to a Satisfiability Modulo Theories problem solvable by brute force ( Haynal & Haynal, 2011 ).

For any information rate R < C and coding error ε > 0, for large enough N, there exists a code of length N and rate ≥ R and a decoding algorithm, such that the maximal probability of block error is ≤ ε ; that is, it is always possible to transmit with arbitrarily small block error.

If an equation can be put into the form f ( x ) = x, and a solution x is an attractive fixed point of the function f, then one may begin with a point x < sub > 1 </ sub > in the basin of attraction of x, and let x < sub > n + 1 </ sub > = f ( x < sub > n </ sub >) for n ≥ 1, and the sequence

Denoted, it is a linear operator of a function f ( t ) with a real argument t ( t ≥ 0 ) that transforms it to a function F ( s ) with a complex argument s. This transformation is essentially bijective for the majority of practical uses ; the respective pairs of f ( t ) and F ( s ) are matched in tables.

In certain areas of computer science, a modified base-k positional system is used, called bijective numeration, with digits 1, 2, ..., k ( k ≥ 1 ), and zero being represented by an empty string.
