An important statement in Quantitative Feedback Theory(QFT) is that the nominal plant can be chosen arbitrarily whether or not it is a member of the plant set. Based on this statement, a design method for non-minimum phase and unstable plants proposed by Horowitz is to choose the stable minimum phase plant as the nominal plant. This report shows this statement is incorrect by several counterexa...

Within a formal framework, where each object is characterized by a set of predicates as a binary sequence of 0 and 1, a nominal level of measurement is discussed. The nominal scale is reinterpreted as a set of predicates, and nominal measurement as an assignment of binary sequences to the objects. One remarkable character of this formalization is a reciprocal relationship between the objects an...

In this article we explore the syntactic and semantic properties of prepositions in the context of the semantic interpretation of nominal phrases and compounds. We investigate the problem based on cross-linguistic evidence from a set of six languages: English, Spanish, Italian, French, Portuguese, and Romanian. The focus on English and Romance languages is well motivated. Most of the time, Engl...

A method is presented for the approximation quality for sorting rules, which is based on Rough Set Data Analysis. Several types of rules are discussed: The “nominal nominal” case (NN) (the classical Rough Set approach), “nominal ordinal” (NO) rules, and “ordinal ordinal” (OO) rules, and its generalisation to “(nominal, ordinal) ordinal” rules (NO-O). We provide a significance test for the overa...

Often microdata sets contain attributes which are neither numerical nor ordinal, but take nominal values from a taxonomy, ontology or classification (e.g. diagnosis in a medical data set about patients, economic activity in an economic data set, etc.). Such data sets must be anonymized if transferred outside the data collector’s premises (e.g. hospital or national statistical office), say, for ...

Most of existing open domain question answering systems predefine the conceptual category to which answers can belong. So, they cannot generate appropriate answers in every case or must use a strategy that handles exceptions when the concept requested in the question is not prepared in the system. In this paper, we suggest a flexible strategy that can generate the candidate answers which corres...

Large, multivariate datasets from high-throughput instrumentation have become ubiquitous throughout the sciences. Frequently, it is of great interest to characterize the measurements in these datasets by the extent to which they represent ‘nominal’ versus ‘contaminated’ instances. However, often the nature of even the nominal patterns in the data are unknown and potentially quite complex, makin...

This paper investigates a methodology of using FM (FraenkelMostowski) sets, and the ideas of nominal set theory, to adjoin name generation to a semantic theory. By developing a domain theory for concurrency within FM sets the domain theory inherits types and operations for name generation, essentially without disturbing its original higherorder features. The original domain theory had a metalan...

This paper presents recent results of the ongoing project aimed at creating the nominal database of the Hungarian WordNet. We present 9 different automatic methods, developed for linking Hungarian nouns to WN 1.6 synsets. Nominal entries are obtained from two different machine-readable dictionaries, a bilingual EnglishHungarian and an explanatory monolingual (Hungarian). The results are evaluat...
