r&d; is one of the most important and suitable strategies government’s policies for increasing of agricultural production and supply. in this study, in addition of economic evaluation of agricultural r&d; and determination of its rate of return, optimal iran’s agricultural r&d; expenditure is determined. so, in this article, ex-post and ex-ante evaluation by using of mathematical programming ap...

This article intends to estimate the optimal value of investment and human capital in R&D sector of Iranian economy using an augmented endogenous growth model. To do so, two issues have been studied. First, an endogenous growth model has been extended to include investment in R&D as an independent variable. In the framework of this model, in order to determine the optimal value of investment an...

Consider a Bayesian optimal design with many support points which poses the problem of collecting data with a few number of observations at each design point. Under such a scenario the asymptotic property of using Fisher information matrix for approximating the covariance matrix of posterior ML estimators might be doubtful. We suggest to use Bhattcharyya matrix in deriving the information matri...

the objective of the current study was to develop and optimize a sublingual tablet formulation of captopril which is an effective drug in the treatment of hypertension. captopril containing tablets were prepared by direct compression method using different ingredients such as polyvinyl pyrrolidone, starch 1500, sodium starch glycolate and lactose (independent variables) and magnesium stearate, ...

Optimal Stopping under Model Uncertainty Ingrid-Mona Zamfirescu The aim of this paper is to extend the theory of optimal stopping to cases in which there is model-uncertainty. This means that we are given a set of possible models in the form of a family P of probability measures, equivalent to a reference probability measure Q on a given measurable space (Ω,F). We are also given a filtration F ...
