ranking fuzzy numbers plays a very important role in linguistic decision making and other fuzzy application systems. in spite of many ranking methods, no one can rank fuzzy numbers with human intuition consistently in all cases. shortcoming are found in some of the convenient methods for ranking triangular fuzzy numbers such as the coefficient of variation (cv index), distance between fuzzy set...

Evaluation of canine cryopreserved semen has the ultimate goal of determining if an individual frozen ejaculate will have acceptable fertility. This is difficult in that there is no accepted normal fertility for the dog. The fertility of the female also plays a crucial role in estimating the fertility of the male. Poor female fertility can make a fertile male appear less fertile. Variability of...

IMPACT OF ENDOGENOUS SLAVE FERTILITY The fertility of household slaves was not entirely outside the control of the slaveowner. Slaveowners influenced slave fertility using a variety of methods, and it is therefore inappropriate to view slave fertility as an entirely exogenous event. A valid instrument for slave fertility is not readily apparent. Under the assumption that slave fertility is corr...
