Ranking fuzzy numbers is an important tool in decision process. In fuzzy decision analysis, fuzzy quantities are used to describe the performance of alternative in modeling a real-world problem. Most of the ranking procedures proposed so far in literature cannot discriminate fuzzy quantities and some are counterintuitive. As fuzzy numbers are represented by possibility distributions, they may o...

Centroid and spread are commonly used approaches in ranking fuzzy numbers. Some experts rank fuzzy numbers using centroid or spread alone while others tend to integrate them together. Although a lot of methods for ranking fuzzy numbers that are related to both approaches have been presented, there are still limitations whereby the ranking obtained is inconsistent with human intuition. This pape...

The notion of Intuitionistic Fuzzy Numbers (IFNs) has been improved in many decision making problems. Ranking of IFNs is one of the techniques that conceptualize IFNs to illustrate order or preference in decision making. Ranking of IFNs plays a very important role in multicriteria decision making, optimization and in many different fields but ranking of IFNs is not a very easy process. As far a...

A method for ranking fuzzy numbers based on the centroid point is proposed and some of its desirable properties are studied. Many different methods have been proposed to deal with ranking fuzzy numbers. Constructing ranking indexes based on centroides is an important. But some weaknesses are found in these indexes. The purpose of this article is to give a new ranking index to rank various numbe...

The motion of a two-dimensional buoyant vortex patch, i.e. patch with uniform density different from the surrounding fluid, is analyzed in terms evolution equations for its centroid, deformation boundary and strength sheet which essential to enforce pressure continuity across boundary. centroid are derived by linear momentum analysis that applying Euler's on boundary, while studied centroid-fix...

The present study uses the envelope modulation spectrum (EMS) measure to assess the effect of language, speaking style, and age on rhythm. Three experiments using a weighted mean of the EMS called the spectral centroid were conducted. The first examined rhythm in English and Croatian across conversational and clear speaking styles. The second experiment compared rhythmic characteristics of mono...

synthetic aperture radar (sar), which has been widely used for earth remote sensing, provides high resolution, day-and-night and weather-independent images for a multitude of applications. design of sar sensors has had some considerations, associated to sar systems issues (microwave propagation, antenna, orbit design and etc.). altitude and attitude errors of sar sensor have a direct effect on ...

Object contour matching has been prevalently used in pattern recognition and content-based indexing and retrieval of digital images. In this paper, the contour descriptors are extracted from a WTMM (Wavelet Transform Modulus Maxima) image, which is produced by a one level biorthogonal wavelet transform and contains curvature points of the contour. The most important WTMMs are further utilized t...

This paper reconfirms that talker identity can be transmitted across languages. Talker discrimination was examined in the ABX paradigm, where the stimuli A and B were utterances by different talkers in the same language and the stimulus X was an utterance by either of A or B in the different language. The average hit rate of this discrimination task was as high as 0.89. The mutual distance matr...
