In this paper, cluster analysis based on fuzzy relations is investigated. Tamura’s max-min n-step procedure is extended to all types of max-t compositions. A max-t similarity-relation matrix is obtained by beginning with a proximity-relation matrix based on the proposed max-t n-step procedure. Then a clustering algorithm is created for the max-t similarityrelation matrix. Three critical max-t c...

We give a detailed account of the one-way quantum computer, a scheme of quantum computation that consists entirely of one-qubit measurements on a particular class of entangled states, the cluster states. We prove its universality, describe why its underlying computational model is different from the network model of quantum computation and relate quantum algorithms to mathematical graphs. Furth...

In many surveys, characteristic of interest is sparsely distributed but highly aggregated; in such situations the adaptive cluster sampling is very useful. Examples of such populations can be found in fisheries, mineral investigations (unevenly distributed ore concentrations), animal and plant populations (rare and endangered species), pollution concentrations and hot spot investigations, and e...

Body area networks is one of the types of wireless area networks which has been created to optimize utilizing hospital resources and for earlier diagnosis of medical symptoms, and ultimately to reduce the cost of medical care. This network like most of the wireless networks is without infrastructure and the embedded sensor nodes in the body have limited energy. Hence, the early power completion...

This paper introduces a text-based chat system designed to support conversations anchored to specific locations of shared images and reports our experience in operating it at WISS2004. Our system is unique in that it focuses on supporting communications scattered around among multiple images, while other systems for anchored conversations are designed for deeper discussions within a single docu...

this research, applied as a survey approach aimed at investigating farmers’ tendency and attitudes toward agricultural water management styles (wmss). therefore, using cochran’s formula and simple random sampling, 244 farmers were selected in doroudzan region, iran. the data were acquired by face-to-face structural interviews and as well through a questionnaire that consisted of closed and open...

the main objective of this study was to investigate how months cluster in any thermal regions based on temperature. for this purpose, the mean of daily temperature data have been provided using 620 synoptic and climatology stations. then, mean temperature was converted for any station, based on solar calendar, and maps of mean daily temperature have been interpolated using kriging method. spati...
