Measures of energy inputs to agriculture should include the gross energy, as well as the other inputs embodied in the material/source until it is used on the field. The efficiency of the system should take into account all the inputs of the farmer until the products reach the first...

[1], 641-643) have given a characterization of the Dirichlet distributions based on the properties of independence of various functions of the random variables (X1, X2, ..., Xk) having a joint continuous distribution over the k-dimensional simplex: 0 = x1 = [Sigma] xi = 1. In this paper we...

The problem of unbiased estimation of the mean life and the reliability for an exponential life distribution using time censored sample data are considered. We prove that there does not exist an unbiased estimator of the mean life based on a time censored sample. On the other hand, for...
