We skip the computer scientist’s view of a grammar for the moment and proceed immediately to that of the formal-linguist. His view is at the same time very ab- stract and quite similar to the layman’s: a grammar is any exact, finite-size, complete description of the langua[r]
The practitioner of formal linguistics, henceforth called the formal-linguist (to distinguish him from the “formal linguist”, the specification of whom is left to the imagination of the reader) again takes an abstracted view of this. A language is a “set” of sentences, and each s[r]
Hyprotech Technical Support Knowledge Base Article 7 • Adiabatic Mode can be used to model the gas blowdown of pressure vessels or piping. No external heat is applied so no parameters need to be entered in this section. Heat flux between the vessel wall and the fluid is modelled as t[r]

Few good-quality studies have compared the frequency of AS among the various ICS formulations. In a Cochrane review comparing beclomethasone, budeso- nide and fluticasone, investigators were unable to make any conclusions regarding the comparative safety of these agents given the lack[r]
The output signals usually correspond to industry standard RS-485 or RS-232 requirements for serial communications. RS-232 is used for single instruments and short cable distances from the computer or DCS. RS-485 is designed for cable runs of up to 4000 feet, and can support multiple i[r]
Therefore, op-amps normally only operate at their maximum open-loop gain up to a few hertz (1 Hz to 10 Hz is typical). Thereafter, the open-loop gain of the amplifier drops off at, usually, about 20 dB per decade. The frequency at which the gain becomes 1 (i.e., unity) can be found from the g[r]
If you are really serious about getting your microengineered device into the market, and have the money to set up a fabrication facility (fab), one of your best options is probably to work with a company (or organization) that has its own facility and is willing to work w[r]
Communication is more about the traffic than the media. Good communication is clear, largely predictable, and systematic, both internally and externally. Although everyone knows this, it’s frightening how many of us forget it. Just because everyone speaks English, don’t assume that e[r]
