With REs, the standard set-notation braces are stripped off, and the set union operator is written as a "+".FA have a textual definition and a graphical counterpart called finite state diagrams. A multitape FA is an FA in which the domain of discourse alphabet is the composition, or ...
有界自动机对应前后文有关语言(CSL),也称为1型语言*PDA-PushdownAutomata,下推自动机,无内存但有堆栈,对应前后文无关语言(CFL),也称为2型语言*DFA-Deterministic FiniteAutomaton,有限状态机是最简单的自动机,无内存,对应正则语言(RL),也称为3型语言。 乔姆斯基在二十世纪五十年代创建了转换-生成语法(Transformation...
In the context of a random hardware failure analysis, a cone of influence (COI) can automatically prune out all faults that are structurally safe without requiring further analysis since anything outside of the cone is by definition classified as a safe fault, shown in Figure 2, below. ...
Questions about a link between the administration of the pediatric measles mumps rubella (MMR) vaccine and subsequent diagnoses of autism have diffused widely through both the professional medical literature as well as through mass-market media publications in recent years.关键词: expert information medi...

KnoBAB showed a new pathway for enhancing temporal queries over customary main memory relational database through the combined provision of both ad hoc relational operators expressing LTLf over relational tables (xtLTLf) and the definition of a query plan represented as a rooted DAG where shared ...
For example, a product construction takes two deterministic finite state automata (DFAs) and generates a single DFA that conceptually runs its two component machines in parallel on the same input string. 2.3. Labeled Transition Systems Definition 1. A labeled transition system (LTS) process, P, ...
As a definition of objective unpredictability, and of objective non-signaling, in quantum mechanics, three types of uncomputability will be considered, all of which are based upon self-referential relations: (i) uncomputability due to the impossibility to know initial conditions with infinite ...
We use this approach to implement a Decision support system that shows the current pandemic situation in Catalonia. Keywords: SEIRD model; COVID-19; SDL; System Dynamics; validation; comparison with other models' validation 1. Introduction The definition of a model that defines the behavior of ...
