A new method for the classification of the QRS patterns in electrocardiograms (ECGs), which belongs to the category of the syntactic methods, is presented in this paper. This method takes into account structural as well as quanlitative information. Some experimental results obtained by this method are also presented. Key wor~L~" Classification, QRS patterns, ECG waveforms, syntactic methods, st...

Monadic predicates for "good" and "bad" are inserted into structures already containing the dyadic predicate "better". A set of logical properties for "good" and "bad" is proposed, and a complete characterization is given of the pairs of monadic predicates that have these properties. It is argued that "good" and "bad" can indeed be defined in terms of "better", and a definition is given that is...

background and purpose: clinical competence has four essential components: knowledge , physical exam , problem solving and communication skill .the communication skill isn’t an optional extra in medical training but it is a core clinical skill. this study is performed in order to determine whether communication skill training for internal medicine and infectious disease residents improves their...

this paper investigates the nature of absolutive case and the syntactic mechanisms underlying its licensing. to this end, two recent minimalist approaches to the syntactic derivation of ergative structure will be introduced. drawing on evidence from the syntactic derivation of clauses with intransitive complex predicates in kurdish, it will be established that the absolutive case is checked by ...

This paper argues that case and inner aspect are independent syntactic relations. In particular I argue that there is no direct syntactic relation between the appearance of accusative case on the direct object and a telic interpretation of a predicate. I argue that accusative case is an Agree relation with v° and aspect is an Agree relation with Asp°, an aspectual head between vP and VP respons...

Necessary and sufficient conditions on a monoid M are found in order that M be isomorphic to the syntactic monoid of a language L over an alphabet X having one of the following properties. In the first theorem L is a /¿-class and Pw¡¡\ Q PL where PL is the syntactic congruence of L and W(L) is the residue of L . In the second theorem L is an infix code; that is, satisfies u, uvw 6 L implying u ...

Elizabeth Prior claims that dispositional predicates are incomplete in the sense that they have more than one argument place. To back up this claim, she offers a number of arguments that involve such ordinary dispositional predicates as ‘fragile’, ‘soluble’, and so on. In this paper, I will first demonstrate that one of Prior’s arguments that ‘is fragile’ is an incomplete predicate is mistaken....

The syntactic complexity of a regular language is the cardinality of its syntactic semigroup. The syntactic complexity of a subclass of the class of regular languages is the maximal syntactic complexity of languages in that class, taken as a function of the state complexity n of these languages. We study the syntactic complexity of prefix-, suffix-, and bifix-free regular languages. We prove th...

We define new subclasses of the class of irreducible sofic shifts. These classes form an infinite hierarchy where the lowest class is the class of almost finite type shifts introduced by B. Marcus. We give effective characterizations of these classes with the syntactic semigroups of the shifts.
