The concept of comfort is an important one for nursing, but because of its complexity, it has not been analyzed, operationalized or structured for nursing science. In this paper, three technical senses of the term are derived from: (a) contemporary and archaic lexical entries; (b) analysis of how the concept is used in contemporary and historical nursing literature; and (c) theoretical support ...

We describe ARACHNE, a concept formation system that, uses explicit constraints on tree structure and local restructuring operators to produce well-formed probabilistic concept trees. We also present a quantitative measure of tree quality and compare the system's performance in artificial and natural domains to that of COBWEB, a well-known concept formation algorithm. The results suggest that A...

Learning accuracy depends on concept variation. The accuracy of six learning systems (C4.5, Grove, Greedy, Fringe, LFC and MRP) is compared using a set of forty test concepts. The selection of these concepts was guided by the existence of structured concepts that appear in diicult real-world domains (such as protein folding). Such concepts often have embedded, implicit structure , which may be ...

We apply formal concept analysis to the understanding, analysis, and code inspection of individual JAVA classes. A concept is a maximal set of methods and fields such that each field is used by every method and each method uses every field. A real life case study shows that the mathematical lattice of concepts is a valuable means in studying the interface of a large class, understanding and dis...

By contrasting Hippocratic and nineteenth century theories of disease, this paper describes important conceptual changes that have taken place in the history of medicine. Disease concepts are presented as causal networks that represent the relations among the symptoms, causes, and treatment of a disease. The transition to the germ theory of disease produced dramatic conceptual changes as the re...

This paper promotes the use of a mathematical concept lattice based upon the binary relation of accesses between methods and fields as a novel visualization of individual JAVA classes. We demonstrate in a detailed reallife case study that such a lattice is valuable for reverseengineering purposes, in that it helps reason about the interface and structure of the class and find errors in the abse...

The purpose of this paper is to review computational methods in structure-soil-structure interaction. As a result of globalization, buildings are located close to each other. This issue happens especially in big cities, making the study of structure-soil-structure interaction as an essential part of structural design process. The effect of soil medium, on which the building structure stands, es...

the global culture concept is one of the importance and the most debatable global concepts which has not been known exactly attend to topics sequence and different views in this theme, nature and aspects related to it. this paper after glance look to the global phenomenon's and express different features try to classification of different social views in global culture concept remove some ...
