In this paper we propose the extension of some aggregation or arithmetic operations between discrete fuzzy numbers to discrete fuzzy number-valued multisets such as the addition, the union and the intersection and, even, the order. For this reason, we prove or recall some properties of discrete fuzzy numbers and we undertake their study on multisets.

This study examined the effects of prior domain knowledge and learning sequences on learning with concept mapping and hypertext. Participants either made a concept map in a first step and then read the hypertext’s contents combined with concept mapping (high activating condition), or they read the hypertext’s contents first and then made a concept map and re-read the hypertext’s contents (low a...

This study was to investigate the stability of self-concept in nonchronic, nonparanoid schizophrenics. Self-Concept, Health-Concept, and Food-Preference questionnaires were administered to 84 Ss. Schizophrenics and controls were divided into failure and nonfailure groups (N = 21 per group). Test-retest method with failure or neutral condition immediately preceding the 2nd testing showed schizop...

Identification of a real time of a change in a process, when an out-of-control signal is present is significant. This may reduce costs of defective products as well as the time of exploring and fixing the cause of defects. Another popular topic in the Statistical Process Control (SPC) is profile monitoring, where knowing the distribution of one or more quality characteristics may not be appropr...

Political Islam in Iran, which initially formed in the guise of Sultāni order, experiences its second form after 1979 Revolution, named popular order. While in both forms, the authority of religion has been accepted in political life, these types of order demonstrate two different experiences of political Islam in Iran. Thus, the comprehension of this new experience of political Islam after the...

We studied the Cauchy problem of fuzzy di erential equations on the basis of introducing the concept of di erentiation which is a generalization of the de nition of H-di erentiability due to Puri and Ralescu (1983), for fuzzy set-valued mappings of real variables whose values are in the fuzzy number space (E; D). The existence and uniqueness theorem is obtained for the Cauchy problem x′=f(t; x)...

Page In the knowing approach, rather than study knowledge as something that people have, the authors focus the process of knowing regarded as something that people do. The social dimension of knowing, enhanced the tacitness of collective knowledge instead of individual mastery within communities of practices and communities of knowing. The assumption of a coherent research perspective based on ...

In this paper, the concept of incidence domination number of graphs  is introduced and the incidence dominating set and  the incidence domination number  of some particular graphs such as  paths, cycles, wheels, complete graphs and stars are studied.
