Event Segment - Timed Language

Timed Language

The universal timed language over an event set and a time interval, is denoted by, and is defined as the set of all possible event segments. Formally,

$\Omega_{Z,}=\{(z,t)^*| z \in Z \cup \{\epsilon\}, t \in \}$

where denotes a none or multiple concatenation(s) of timed events. Notice that the number of events in an event segment $\omega \in \Omega_{Z,}$ can be one of zero, finite or infinite. Infinitely many events in an event segment $\omega \in \Omega_{Z,[t_l, t_u]}$ implies that, however $t_u - t_l \rightarrow \infty$ does not imply infinite many events in it.

A timed language over an event set and a timed interval is a set of event segments over and $[t_l, t_u]$ . If is a language over and, then $L \subseteq \Omega_{Z, }$ .

Famous quotes containing the words timed and/or language:

“He bends to the order of the seasons, the weather, the soils and crops, as the sails of a ship bend to the wind. He represents continuous hard labor, year in, year out, and small gains. He is a slow person, timed to Nature, and not to city watches. He takes the pace of seasons, plants and chemistry. Nature never hurries: atom by atom, little by little, she achieves her work.”
—Ralph Waldo Emerson (1803–1882)

“The style of an author should be the image of his mind, but the choice and command of language is the fruit of exercise.”
—Edward Gibbon (1737–1794)
