data obtained in association with many real-life random experiments from different fields cannot be perfectly/exactly quantified.hspace{.1cm}often the underlying imprecision can be suitably described in terms of fuzzy numbers/values. for these random experiments, the scale of fuzzy numbers/values enables to capture more variability and subjectivity than that of categorical data, and more accura...

in this paper, by using a new approach on distance between two fuzzy numbers, we construct a new ranking system for fuzzy number which is very realistic and also matching our intuition as the crisp ranking system on r.

Mathematicians have been fascinated for centuries by the properties and patterns of numbers. They noticed that some numbers are equal to sum all their factors (not including number itself). Such called perfect Thus a positive integer is if it its proper divisors. The search began in ancient times. four 6, 28, 496, 8128 seem known from In this paper, we will investigate important We give easy si...

introduction: both initiation and maintenance of spermatogenesis are hormonally regulated by fsh and testosterone. in this study, the effects of fsh and testosterone on the in vitro maturation of fresh and frozen- thawed round spermatids were determind. material and methods: cell suspension was isolated from testis of nmri male mice (8-10 weaks old) and divided into two groups .the first part w...

the purpose of this paper is to study the fuzzy fractional differentialequations. we prove that fuzzy fractional differential equation isequivalent to the fuzzy integral equation and then using this equivalenceexistence and uniqueness result is establish. fuzzy derivative is considerin the goetschel-voxman sense and fractional derivative is consider in theriemann liouville sense. at the end, we...

the plaque forming unit (pfu) and tissue culture infectious dose50 (tcid 50 ) methods are used for evaluation of vaccine heat stability and effect of various stabilizers on thermal stability of vaccines. the aim of present study is using real-time pcrtechniquefor estimation of vaccine degradation rate and thermal stability of measles vaccines. lyophilized measles vaccines containing three vario...
