For every NFA a deterministic finite automaton (DFA) can be found that accepts the same language. Therefore, it is possible to convert an existing NFA into a DFA for the purpose of implementing a (perhaps) simpler machine. This can be performed using the powerset construction, which may lead to an exponential rise in the number of necessary states.
In economics, valuation effects of a country are the changes in the value of assets held abroad, minus the changes in the value of domestic assets held by foreign investors. The traditional balance of payment identity ignores valuation effects, only recognizes that changes in the net foreign assets (NFA) are fully captured by the current account.
Net foreign assets. In economics, the concept of net foreign assets relates to balance of payments identity. The net foreign asset (NFA) position of a country is the value of its net claims on the rest of the world (RoW), i. e. the value of the assets that country owns abroad, minus the value of the domestic assets owned by foreigners: The net ...

Powerset construction. In the theory of computation and automata theory, the powerset construction or subset construction is a standard method for converting a nondeterministic finite automaton (NFA) into a deterministic finite automaton (DFA) which recognizes the same formal language. It is important in theory because it establishes that NFAs ...
Thompson's construction. In computer science, Thompson's construction algorithm, also called the McNaughton–Yamada–Thompson algorithm, [1] is a method of transforming a regular expression into an equivalent nondeterministic finite automaton (NFA). [2] This NFA can be used to match strings against the regular expression.

Generalized nondeterministic finite automaton. In the theory of computation, a generalized nondeterministic finite automaton (GNFA), also known as an expression automaton or a generalized nondeterministic finite state machine, is a variation of a nondeterministic finite automaton (NFA) where each transition is labeled with any regular expression.
