查询词典 modeling

The numerical modeling process for SVE remediation is achieved after a steady alternant direction implicit finite difference format is developed. In this paper, as an example, the 60 days remediation under 4 different conditions is simulated, which proves that the clear-up result is mainly governed by soil permeability.

At the same time , we discuss the determinism and nondeterminism of formula-clock automata and the closure propertied under Boolean operation of the language which is accepted by formula-clock automata. We also prove the expressive equivalence between the deterministic formula-clock automata and the nondeterministic formula-clock automata. This means that every nondeterministic formula-clock automata can be transformed to a deterministic formula-clock automata which exactly accept the timed language identified by the fomer.We also extend timed words to infiniteness and define the formula-clock Buchi automata and the formula-clock Muller automata. At last, we show its application in formal verification and modeling of real-time system.
