A GPDA is formally defined as a 6-tuple:

GPDA's and PDA's are equivalent in that if a language is recognized by a PDA, it is also recognized by a GPDA and vice versa.

Computation rules for a GPDA are the same as a PDA except that the a < sub > i + 1 </ sub >' s and b < sub > i + 1 </ sub >' s are now strings instead of symbols.

The GPDA filed an injunction to bar Patrese from participating in the 1978 United States Grand Prix weekend, which was allowed, and Patrese did not take part in anything related to the race weekend.

Several top level names, including Michael Schumacher, Damon Hill, and Gerhard Berger, were instrumental in the setup and running of the GPDA, and they took the decision to install a temporary chicane at the Nissan corner, to attempt to slow the cars down before the La Caixa Hairpin.

Following the tragic accidents during the season the GPDA demanded the FIA improve the safety of Formula 1.

In the aftermath of the Italian Grand Prix 2 weeks previously, the Grand Prix Drivers ' Association ( GPDA ) had a meeting centering around Riccardo Patrese, the driver whom the GPDA blamed for the multiple car pile-up and death of Peterson at Monza.

After lengthy debates and negotiation between the GPDA, FISA and FOCA the dispute was settled in favour of the drivers, and the clause was dropped.

Formally, the set of all context-free languages is identical to the set of languages accepted by pushdown automata ( PDA ).

A personal digital assistant ( PDA ), also known as a palmtop computer, or personal data assistant, is a mobile device that functions as a personal information manager.

When the PDA is repaired or replaced, it can be " re-synced " with the computer, restoring the user's data.

Some users find that data input is quicker on their computer than on their PDA, since text input via a touchscreen or small-scale keyboard is slower than a full-size keyboard.

Transferring data to a PDA via the computer is therefore a lot quicker than having to manually input all data on the handheld device.

Kairos Systems ( KAMPDA ) is a complete audit and surveillance solution ( EDCRS-Electronic Data Capture and Reporting Solution ) allowing the user to record observations and rapidly disemminate feedback to nominated recipients, using the SoMo 650 PDA from Socket Mobile.

Universal design is relevant to PDAs as well as other technology, and a viable solution for many user-access issues, though it has yet to be consistently integrated into the design of popular consumer PDA devices.

In computer science, a pushdown automaton ( PDA ) is

The PDA is used in theories about what can be computed by machines.

A PDA is formally defined as a 7-tuple:

The letter ( epsilon ) denotes the empty string and the component of the transition relation is used to formalize that the PDA can either read a letter from the input, or proceed leaving the input untouched.

The following is the formal description of the PDA which recognizes the language by final state:

Where the grammar generates a terminal symbol, the PDA reads a symbol from input when it is the topmost symbol on the stack ( match ).

Technically, given a context-free grammar, the PDA is constructed as follows.

The converse, finding a grammar for a given PDA, is not that easy.

The trick is to code two states of the PDA into the nonterminals of the grammar.

* SKL is a hand-held PDA that handles, views, stores, and loads SOI, Key, and electronic protection data.

Some of Acorn's former subsidiaries live on today — notably ARM Holdings, which is globally dominant in the mobile phone and PDA microprocessor market.

It is a hardware specification for a handheld-sized computer, personal digital assistant ( PDA ), that runs the Microsoft ' Windows Mobile Classic ' operating system.

It is also possible, but equally doubtful, that he actually shot down the hundreds of men with which his legend credits him.

Let me pass over the trip to Sante Fe with something of the same speed which made Mrs. Roebuck `` wonduh if the wahtahm speed limit '' ( 35 m.p.h. ) `` is still in ee-faket ''.

It is these other differences between North and South -- other, that is, than those which concern discrimination or social welfare -- which I chiefly discuss herein.

It became the sole `` subject '' of `` international law '' ( a term which, it is pertinent to remember, was coined by Bentham ), a body of legal principle which by and large was made up of what Western nations could do in the world arena.

Of greater importance, however, is the content of those programs, which have had and are having enormous consequences for the American people.

Recognizing that the Rule of Law is `` a dynamic concept which should be employed not only to safeguard the civil and political rights of the individual in a free society '', the Congress asserted that it also included the responsibility `` to establish social, economic, educational and cultural conditions under which his legitimate aspirations and dignity may be realized ''.

For better or for worse, we all now live in welfare states, the organizing principle of which is collective responsibility for individual well-being.

That is particularly true of sovereignty when it is applied to democratic societies, in which `` popular '' sovereignty is said to exist, and in federal nations, in which the jobs of government are split.
