Construction of an FA from an RE - We can use Thompson's Construction to find out a Finite Automaton from a Regular Expression. We will reduce the regular expression into smallest regular expressions and converting these to NFA and finally to DFA.
Visualize the Thompson-McNaughton-Yamada construction NFA for a given regular expression. The subset construction algorithm is also applied to the resultant NFA, resulting in a language-equivalent deterministic finite-state automata (DFA).Enter a regular expression: e.g. a*(b|cd)* ...

Suppose the scale of the fuzzy UML model FUML is N = NFC + NFA + NFS + NFR + NFH + NFG + NI, where NFC, NFA, NFS, NFR, NFH, NFG and NI denotes the cardinality of the sets of fuzzy Construction of Fuzzy Ontologies from Fuzzy UML Models classes, fuzzy attributes, fuzzy ...
Deterministic Finite Automaton (DFA) is the basic data structure for regular expression matching. Though DFA satisfies the need of real-time processing of network traffic in on-line systems, the construction of DFA is very time-consuming that prevents it from being applied on large sets of ...
In [2], Antimirov introduced the notion of partial derivative of a regular expression, that lead to another definition and construction of the equation automaton. It is an 𝜖ϵ-free NFA which has in general smaller number of states and transitions than the well-known position automaton [3...
On the one hand, oxygen, as the electron acceptor at the end of the respiratory chain, combines with the paired hydrogen atoms removed from the metabolites during the respiratory chain to form water, and can continuously generate ATP (adenosine triphosphate, which provides direct energy for the ...
