This makes the DPDA a strictly weaker device than the PDA. For example, the language L p of even-length palindromes on the alphabet of 0 and 1 has the context-free grammar S → 0S0 | 1S1 | ε. If a DPDA for this language exists, and it sees a string 0 n , it must use its stack to memorize the length n , in order to be able to distinguish its ...
Prior to the Prescription Drug User Fee Act (PDUFA), median approval times of New Drug Applications ranged between 21 and 29 months. [2] The Prescription Drug User Fee Act was first passed in 1992 to facilitate the funding of the Food and Drug Administration while ensuring a more predictable timetable for drug approvals. [3]
The FDA estimates that operating costs for the year 2017 will be $878,590,000. The FD&C Act specifies that one-third of the total fee revenue is to be derived from application fees, one-third from establishment fees, and one-third from product fees (see section 736(b)(2) of the FD&C Act).
In most countries, a marketing authorisation is valid for a period of 5 years. After this period, one should apply for renewal of the marketing authorisation, usually by providing minimal data proving that quality, efficacy and safety characteristics are maintained and the risk-benefit ratio of the medicinal product is still favourable.
State fuel taxes have a similar user-fee model, including pilot programs that shift from a per-gallon fee to one based upon distance. [1] In international development, user fees refer to a system fee for basic health care, education, or other services implemented by a developing country to make up for the costs of these services.
The Defense Finance and Accounting Service (DFAS) is an agency of the United States Department of Defense (DOD), headquartered in Indianapolis, Indiana.The DFAS was established in 1991 under the authority, direction, and control of the Under Secretary of Defense (Comptroller)/Chief Financial Officer to strengthen and reduce costs of financial management and operations within the DOD.
The notion of the DCFL is closely related to the deterministic pushdown automaton (DPDA). It is where the language power of pushdown automata is reduced to if we make them deterministic; the pushdown automata become unable to choose between different state-transition alternatives and as a consequence cannot recognize all context-free languages. [1]
A transition without consuming an input symbol is called an ε-transition and is represented in state diagrams by an arrow labeled "ε". ε-transitions provide a convenient way of modeling systems whose current states are not precisely known: i.e., if we are modeling a system and it is not clear whether the current state (after processing some ...
