In geometry an Archimedean solid is a highly symmetric, semi-regular convex polyhedron composed of two or more types of regular polygons meeting in identical vertices.

Since longer symmetric keys require exponentially more work to brute force search, a sufficiently long symmetric key makes this line of attack impractical.

* The relation " is approximately equal to " between real numbers, even if more precisely defined, is not an equivalence relation, because although reflexive and symmetric, it is not transitive, since multiple small changes can accumulate to become a big change.

The gardens in the 16th and 17th century were symmetric, proportioned and balanced with a more classical appearance.

The nucleus ( upper right ) in helium-4 is in reality spherically symmetric and closely resembles the electron cloud, although for more complicated nuclei this is not always the case.

According to Puglisi, in the post-1960 period the Times displays a more symmetric type of watchdog behaviour, just because during presidential campaigns it also gives more coverage to the typically Republican issue of Defense when the incumbent President is a Democrat, and less so when the incumbent is a Republican.

This is why, unlike symmetric key algorithms, a public key algorithm does not require a secure initial exchange of one ( or more ) secret keys between the sender and receiver.

contributions to DSL was his insight that an asymmetric arrangement offered more than double the bandwidth capacity of symmetric DSL.

This strong, more nearly symmetric response also makes CMOS more resistant to noise.

In computing, symmetric multiprocessing ( SMP ) involves a multiprocessor computer hardware architecture where two or more identical processors are connected to a single shared main memory and are controlled by a single OS instance.

Bilateria ( bilateral animals, including humans ) are more or less symmetric with respect to the sagittal plane.

Breaking a symmetric 256-bit key by brute force requires 2 < sup > 128 </ sup > times more computational power than a 128-bit key.

This can be seen in the more Roman-influenced Federal structure's ornate, colossal Corinthian columns of its façade, which is also embellished by Corinthian pilasters and a symmetric arrangement of sash windows piercing the two stories of the façade.

The symmetric structure of SRAMs also allows for differential signaling, which makes small voltage swings more easily detectable.

The identity relation is the archetype of the more general concept of an equivalence relation on a set: those binary relations which are reflexive, symmetric, and transitive.

The t-distribution is symmetric and bell-shaped, like the normal distribution, but has heavier tails, meaning that it is more prone to producing values that fall far from its mean.

If A has real entries and is symmetric ( or more generally, has complex-valued entries and is Hermitian ) and positive definite, then A can be decomposed as

This feature gives the NAM a more annular ( or zonally symmetric ) structure.

Note that the above method will determine the smallest of the two possible angles — it will never be more than 180 °, as the value of the cosine is symmetric between the upper and lower halves of the unit circle.

Such is the case for non-negative symmetric operators ( or more generally, operators which are bounded below ).

The round design of the structure and the symmetric oval shape of the 4, 100 m² ( 44, 100 ft² ) arena floor results in more rows along the length of the floor.

They crowded him in that threatening way once more, forced him to give in.

Belief in the traditional way of life persists much more in the older states than in the new ones.

Even two decades ago in Go Down, Moses Faulkner was looking to the more urban future with a glimmer of hope that through its youth and its new way of life the South might be reborn and the curse of slavery erased from its soil.

I believe that what I do has some effect on his actions and I have learned, in a way, to commune with drunks, but certainly my actions seem to resemble more nearly the performance of a rain dance than the carrying out of an experiment in physics.

Nothing is more revealing of the way of life and literary aspirations of this group than their attitude toward sex.

When words can be used in a more fresh and primitive way so that they strike with the force of sights and sounds, when tones of sound and colors of paint and the carven shape all strike the sensibilities with an undeniable force of data in and of themselves, compelling the observer into an attitude of attention, all this imitates the way experience itself in its deepest character strikes upon the door of consciousness and clamors for entrance.

And it is clearly argued by Lord Percy of Newcastle, in his remarkable long essay, The Heresy Of Democracy, and in a more general way by Voegelin, in his New Science Of Politics, that this same Rousseauan idea, descending through European democracy, is the source of Marx's theory of the dictatorship of the proletariat.

Whether you experienced the passion of desire I have, of course, no way of knowing, nor indeed have I wished with even the most fleeting fragment of a wish to know, for the fact that one constitutes by one's mere existence so to speak the proof of some sort of passion makes any speculation upon this part of one's parents' experience more immodest, more scandalizing, more deeply unwelcome than an obscenity from a stranger.

I mean something more like Freud's concept of the utility of `` play '' to a small child: he plays `` house '' or `` doctor '' or `` fireman '' as a way of mastering slightly frightening experiences, reliving them imaginatively until they are under control.

Those who do have occasion to deal with the invasions in a more general way, like T.W. Shore and Arthur Wade-Evans, are on the side of a gradual and often peaceful Germanic penetration into Britain.

High school students have more sense of the way to dress than college students.

No, they must look the other way and climb one more painful step up the ladder.

It could continue this way, hitting 106 and more in the Valley, Joe McFeeley knew, into October.

Nevertheless, they made naught of Marx's prophecy that capitalism would never pay the `` workers '' -- to use Marx's word -- more than a subsistence wage, with the consequence that increased productivity must inevitably find its way into the capitalists' pockets with the result, in turn, that the gap between the rich and the poor would irrevocably widen and the misery of the poor increase.

It would be even more valuable because that same aircraft could immediately destroy any targets it discovered -- no need to wait for a missile to come all the way from the United States with the chance that the target, if it were mobile, would be gone.

Or a bored dog because you are more interested in something else -- maybe the way you look, or the date you have after the Class, or you are just doing this to please the parents.

The most effective way to develop more places for more sportsmen to shoot is to encourage properly managed shooting preserves.

The revolution is well under way, but much more remains to be done

and which, more often than all these, conveys a welter of feelings which could in no way be conveyed by any number of words, words which are so unlike this welter in being formed and discrete from one another.
