In order to survive, maintain advantage, and gain foothold in the market, brand needs innovation, and precedence over the rivals in technology, service and other respects, and it is necessary for the brand to offer, more comprehensive and satisfactory services and meet the customers'higher demands to maintain brand.
Thermoelastic Infrared Image Safe Testing System is a key item of the national science instrument, and passed technique identify in Dec. 29, 2002. The experts uninfected that is an original creativity technique and international precedence level.
John Rawls has fallen over himself for the view that liberty can be confined only for the needs of equality of society cooperate system, but liberty is the precondition of equality, therefore, liberty is precedence .
This paper develops Belozersky's early idea of the precedence of RNA in the origin of life on the Earth.
Problems of solvability and choice of algorithms for decision making by precedence
While a global precedence effect (i.e., faster responses to global than local targets and stronger global-to-local interference than the reverse) was observed, TMS decreased global-to-local interference whereas increased local-to-global interference.
The problem is formulated as a Hybrid Flow Shop Scheduling problem with precedence constraint, setup times and blocking (HFSS-B).
The paper considers four criteria for causality: precedence, coherence with existing knowledge, dose-related liability, and understandability of mechanisms.
BLR(K) grammar is a kind of grammar belonging to the LR family from which a concise Floyd Evans production program can be mechanically generated. In this paper the conditions for the BLR(K) grammar are given which are both necessary and satisfactory. It is also shown that the BLR (K) grammar properly includes the weak precedence grammar.
A large class of precedence grammar——the generalized precedence grammar is defined using a new concept of generalized precedence. If (X,a) is a pair of symbols of any context free grammar, then there is at most one generalized precedence relation between X aad a. Therefore the class of generalized precedence grammar is a superclass of the weak precedence grammar. The new grammar is unambiguous and an efficient parsing algorithm is also given.
A new class of grammar—— the GP grammar is defined. It is a superelass of the generalized precedence grammar defined by Mr. Lu Ru-qian.It is shown that a grammar can be correctly parsed by the matching precedence parsing algorithm if and only if it is a GP grammar.
