results of numerical simulation of intra-cloud electrification depend on a mechanism that determines the sign and magnitude of charge transferred to hydrometeors (including graupels and ice crystals), through their collision (mansell et al., 2005). some of the microphysical processes play an important role in the above mechanism. in order to estimate the amount and sign of the transmitted charg...

Considering Rao et al. (2004) and Di Crescenzo and Longobardi (2009) studies, Misagh et al. (2011) proposed a weighted information which is based on the cumulative entropy called Weighted Cumulative Entropy (WCE). The above-mentioned model is a Shiftdependent Uncertainty Measure. In this paper, we examine some of the properties of WCE and obtain some bounds for that. In order to ...

introduction:.color is the first quality attribute of food evaluated by consumers, and is therefore an important quality component of food which influences consumer’s choice and preferences (maguire, 1994). color measurement of food products has been used as an indirect measure of other quality attributes such as flavor and contents of pigments because it is simpler, faster and correlates well ...

introduction: flavor plays a pivotal role in consumer satisfaction and further consumption of foods. most available aroma compounds are synthetic and most of consumers tend to avoid them as they are of the idea that the chemical flavors are toxic or detrimental to their health. recently, the market of flavors from natural sources is shifting its focus on application rather than synthetic flavor...
