Rather, rock use remained aperiodic throughout the season despite increases in risk.

No small aperiodic set of Wang cubes has been known.

Because of this, the aperiodic functionality is not used in practice.

A task can be classified as either a periodic or aperiodic process.

Today there is a large amount of literature on aperiodic tilings.

It is the first known example of a single aperiodic tile, or "einstein".

The same approach was later shown to lead to aperiodic sets of 13 tiles, the minimum known.

Light curves can also be aperiodic, that is they are irregular with no pattern.

For such a coloring to exist at all, it is necessary that G be aperiodic.

With a strongly connected and aperiodic network the whole group reaches a consensus.

Aperiodic sound is produced by two different types of disturbance:

Another kind of sound is irregular or aperiodic and so appears to be just random variations in air pressure.

However, for more families of lines this construction produces aperiodic tilings.

Complex and aperiodic sound waves can often be assigned a pitch by this method.

Guideline 13 - Project monitoring includes aperiodic review of climate change data.

The question of whether an aperiodic set exists with only a single prototile is known as the einstein problem.

An aperiodic sequence is one which is not ultimately periodic.

There is no mathematical concept of 'aperiodic tiling' per se.

The second type, icosahedral quasicrystals, are aperiodic in all directions.

They're aperiodic crystal structures in clays-but still, they can reproduce.

However, the tiles shown below, force the chair substitution structure to emerge, and so are themselves aperiodic.

They can be aperiodic or periodic (with arbitrarily large unit cells) in the other direction.

Faraday waves have been observed to form large patches of aperiodic patterns.

It forms an aperiodic pattern known as a quasicrystal.
