The purpose of this paper is to introduce the concept of soft double fuzzy semi-topogenous order. Firstly, we give the definition of soft double fuzzy semi-topogenous order. Secondly, we induce a soft double fuzzy topology from a given soft double fuzzy semi-topogenous order by using soft double fuzzy interior operator.

This paper offers a state-of-the-art working definition for the concept of Critical Thinking (CT hereafter) in an attempt to provide a framework for the development of an operational definition for this complex concept. Having studied various definitions and models, proposed for CT by major figures in the field, the key defining features of this rich concept were identified and classified. Base...

This paper first improves Chen and Hsieh’s definition of generalized fuzzy numbers, which makes it the generalization of definition of fuzzy numbers. Secondly, in terms of the generalized fuzzy numbers set, we introduce two different kinds of orders and arithmetic operations and metrics based on the λ-cutting sets or generalized λ-cutting sets, so that the generalized fuzzy numbers are integrat...

Studies of the structure of atoms and ions (ultracold to relativistic included) as well as their twobody interactions with photons, electrons and other particles require accurate methods for the description of such objects. In order to obtain accurate values of atomic quantities it is necessary to account for relativistic and correlation effects. Relativistic effects may be taken into account a...

The report outlines the derived syntax provided within the HP-SL specification language to enable the definition ofrecord and union types. It describes the notation at two levels. First it describes the requirements for such a not.ation by way of an example the informally defines the derived short-hand notation. Secondly it provides a det.ailed definition by way of axiom schemas of the translat...

This paper proposes an ontological definition of services. Such a definition is one of the fundamentals of service research. The understanding of essentialities of the notion of services as its definition, which differentiates services from the other notions, contributes proper modeling and conceptualization of services in services design and knowledge management of services. The existing defin...
